[0004]When caring for another person, turning on a light may allow a caregiver to inspect and assess needs of the other person more accurately, but runs a risk of awakening the other person, by the light and/or because of the sound when turning the light on. Alternatively, if the caregiver does not turn on the light, the other person is less likely to wake up, but the caregiver is less able to inspect and assess the other person in the darkness.
[0005]Additionally, certain wavelengths of light are more likely to cause a wakeful response to those exposed to them. Many physiological parameters including body temperature, blood pressure, liver function, muscle strength, mood, alertness, and many hormones, including the sleep hormone melatonin, exhibit daily oscillations with a periodicity of about a day (Latin: ‘circa′=about, ‘diem′=a day). Circadian rhythms are “entrained” by so-called zeitgebers to a particular phase to promote alignment of the inner clock with the outside world. The main zeitgeber is ˜480 nm blue light. Exposure to this wavelength, which is present in daylight as well as most electrical lighting, triggers activation of the light receptor melanopsin in the ipRGCs, a special non-vision-forming cell type in the retina. The light signal is transmitted from the eyes to the suprachiasmatic nucleus, a dedicated brain area which regulates most circadian processes in the body and is therefore considered the body's “master clock.”
[0006]Certain wavelengths of light (e.g., wavelengths near 480 nm) can disrupt the circadian clock, suppresses the sleep hormone melatonin, and is therefore a powerful modulator of our sleep/wake cycles. After sunset, melatonin can rise, and sleep is promoted. Research shows that electrical lighting in our homes and light emitted from screens including e-readers and smartphones is highly effective in disrupting circadian rhythms, suppressing melatonin production in the evening, and causing sleep loss in both adults and children, creating a link between the high prevalence of insomnia and electrical lighting. On the other hand, indoor lighting is typically not strong enough to elicit the positive physiological effects of light during the day.
[0007]Given light's therapeutic properties, including impact on circadian rhythms, light interventions have been studied as a tool to improve sleep and increase human health and well-being. Bright light therapy for insomnia as well as other health conditions including depression has been proven effective in clinical trials, and the effect of circadian lighting-increasing the aspect of 480 nm-enriched (melanopic) light during the day and decreasing melanopic light exposure in the evening and during the night—has been shown to help office and shift workers, travelers, students and adolescents, NICU babies, nursing home residents, Alzheimer patients, cancer patients and new mothers to improve sleep, reduce inflammation, improve alertness, memory, cognition and mood, reduce jetlag, feel better and be more productive reduce fatigue, and enhance effectiveness of some pharmacological substances.
[0008]While circadian lighting has a number of health benefits, it is not readily available for the general public. Accordingly, there is a need for a circadian lighting solution that is gentle enough to not awaken a sleeping person or to alter the circadian rhythms of the caregiver, and that is quiet enough to not disrupt a sleeping person when turned on or otherwise actuated. There is additional need for active circadian devices in therapeutic, clinical, and/or hospital settings.
BRIEF OVERVIEW
[0009]This brief overview is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This brief overview is not intended to identify key features or essential features of the claimed subject matter. Nor is this brief overview intended to be used to limit the claimed subject matter's scope.
[0010]One type of an environment sensing and/or altering device, also known as a sleep lamp, may be a self-contained device that emits light in a spectrum designed not to impact a sleep cycle of those exposed to the light. In some embodiments, the sleep lamp may optionally be included as a part of a distributed system, such as a therapeutic lighting and digital health system, as an edge device. The sleep lamp may be used at least for emitting light and/or sound to alter an environment within a room, and/or for sensing environmental conditions (e.g., light, sound, temperature, humidity, etc.) in a room.
[0011]In some embodiments, the sleep lamp may be a capacitive touch lamp. The sleep lamp may initially be in an “off” state (e.g., unpowered), and an activation may advance an illumination of the lamp to a dim setting. One or more subsequent activations of the sleep lamp may increase the brightness. Further activation of the sleep lamp may return the lamp to the off state.
[0012]In some embodiments, the sleep lamp may optionally include an audio pickup or sensor. The audio sensor may be used to identify noises associated with wakefulness in a room. For example, the sensor may determine that a baby is crying in the room. In some embodiments, the determination may include local and/or remote machine learning processes for identifying and categorizing sounds as either sounds indicating wakefulness (e.g., crying, talking etc.) or sounds indicating sleep (e.g., snoring). In embodiments, the audio sensor may use an audio level threshold determination. Detection of the sound threshold or classified sounds indicating wakefulness may be used to trigger automatic dim illumination. This may allow a parent or other caretaker to audit the room without even being close to the lamp.
[0013]In some embodiments, the sleep lamp may include a noise generator for emitting sounds (e.g., a white noise generator or other audio generator such as gentle tones, rain sounds, etc.). The noise generator may optionally be configured to automatically activate upon detection of the sound threshold or classified sounds indicating wakefulness. The automatic activation of light and/or audio output in response to the audio input trigger may enhance the use of the lamp and as illumination and safety device by the parent or caretaker. A volume of the noise generator may be controlled via activation of the sleep lamp, in a manner similar to control of the lamp (e.g., with soft->medium->loud->off controls). In embodiments, the noise generator and the lamp may be controlled independently. The sleep lamp may detect activation patterns and may interpret the detected patterns as signals, allowing patterns to be more complex than a single touch or activation, and allowing more controls.
[0014]In another embodiment the sleep lamp may communicate at least a portion of (e.g., all) detection and control events to a digital health platform, such as a circadian data platform. The platform may analyze behavior based on the received data, including changes or improvement in sleep pattern reinforcement, and parent or caretaker control behavior for sleep training purposes. Data trends such as time of day and length of sleep may be transmitted and analyzed for augmented lamp usage. Sleep lamp responses (e.g., altering audio volume or light level) may be initiated automatically to help soothe a user (e.g., a baby) back to restful sleep when the user begins to stir at undesired times.
[0015]Both the foregoing brief overview and the following detailed description provide examples and are explanatory only. Accordingly, the foregoing brief overview and the following detailed description should not be considered to be restrictive. Further, features or variations may be provided in addition to those set forth herein. For example, embodiments may be directed to various feature combinations and sub-combinations described in the detailed description.

I. Overview
[0035]This overview is provided to introduce a selection of concepts in a simplified form that are further described below. This overview is not intended to identify key features or essential features of the claimed subject matter. Nor is this overview intended to be used to limit the claimed subject matter's scope.
[0036]A sleep lamp may be used independently or, optionally, as part of a therapeutic lighting, sensing, and software system. In some embodiments, the sleep lamp may include one or more sensors for gathering information about conditions in the area surrounding the sleep lamp, and/or for gathering information regarding one or more touches of a designated area of the lamp. In some embodiments, the sleep lamp may communicate with a digital health platform including a backend computing device. For example, the sleep lamp may provide data gathered from the one or more sensors to the backend computing device. In some embodiments, the sleep lamp may optionally receive one or more commands from the backend computing system to control the lamp. Additionally or alternatively, the sleep lamp may include a processor for analysis of the data gathered by the one or more sensors.
[0037]The sleep lamp may be a device used to administer therapeutic light to a user, such as light in a spectrum designed not to reset the circadian rhythms of the user. In some embodiments, the sleep lamp may also be used for additional purposes, such as generating sounds for a user, sensing ambient light conditions in the vicinity of a user, sensing noise conditions in the vicinity of the user, and receiving commands from a user.
[0038]Both the foregoing overview and the following detailed description provide examples and are explanatory only. Accordingly, the foregoing overview and the following detailed description should not be considered to be restrictive. Further, features or variations may be provided in addition to those set forth herein. For example, embodiments may be directed to various feature combinations and sub-combinations described in the detailed description.
II. System Configuration
[0039]One possible embodiment of the present disclosure provides a software and hardware platform comprised of a set of components. For example, the components may be divided into a set of structural components, and a set of electrical components. The components may include, but are not limited to:
A. Housing
[0040]FIG. 1 illustrates a perspective view of a sleep lamp 100 (e.g., a therapeutic light emitting device) consistent with an embodiment of the disclosure. As shown in FIG. 1, the sleep lamp 100 includes a housing 102 that substantially encloses the lamp. In embodiments, the housing 102 may include frame members 104, one or more leaf members 106, a diffuser 108, a cup support member 110, a base 112, and a set of feet 114. The housing 102 may be formed from durable materials, such as wood, metal, and/or various plastics. In some embodiments, the housing is preferably formed from a sound dampening material or a material designed not to emit sound when contacted (e.g., by a user). In particular, wood and plastic may provide sound dampening characteristics in addition to their durability. In some embodiments, various portions of the housing may be formed from and/or may include different materials. Alternatively, all portions of the housing may be formed from or include the same material. As a particular example, all members of the housing may be formed from or may include wood.
[0041]The housing 102 may include one or more frame members 104. As shown in FIG. 1, the housing 102 may include a pair of frame members 104. The one or more frame members 104 may generally describe a shape of the sleep lamp 100. For example, as shown in FIG. 1, the frame members 104 describe a generally oval shape, and the sleep lamp 100 is shaped as an oval prism. In some embodiments, each frame member 104 may define a side of the sleep lamp 100, and may make up of a body volume of the sleep lamp.
[0042]The housing 102 may include one or more leaf members 106. In embodiments, each leaf member 106 may have a shape relatively similar to that of the frame members 104. In some embodiments, each leaf member 106 may be formed from a non-conductive material, such as wood or plastic. The leaf member 106 may be designed to help minimize noise created by actuation of the lamp 100 by a user. In some embodiments, the leaf member 106 is formed from a sound dampening material or a material designed not to emit sound when contacted (e.g., by a user). The non-conductive material may have a capacitive electrode 107 embedded therein. The conducting portion of the capacitive electrode 107 may be formed from a conductive material (e.g., a metal such as copper, aluminum, or silver; a conductive ceramic such as Titanium Dichloride; other conductive materials such as Indium Tin Oxide; etc.). Various conductive materials may be used to form the capacitive electrode 107. In embodiments, the capacitive electrode 107 may be formed as an embedded disc, an embedded mesh, or any other shape useful for allowing conduction through the non-conductive leaf member 106.
[0043]In some embodiments, the capacitive electrode 107 may be formed by depositing the conductive material on a polymer thread, such as a nylon thread. Such deposition may be achieved by Chemical Vapor Deposition (CVD) and/or similar deposition processes. The polymer thread having the conductive material deposited thereon may be woven into a conductive cloth.
[0044]In other embodiments, the capacitive electrode 107 may be formed as a metal covering, such as a woven metal wire, metal screen, or perforated metal foil. Metal structures such as these are useful, but may have drawbacks. In particular, the metal covering may be relatively thick and heavy when compared to the conductive cloth, and may not adhere well to the leaf member 106 due to its non-porous nature. Additionally, the metal covering may not create a high enough projected surface area to be able to act as a good capacitive touch electrode 107.
[0045]To form the leaf member 106, the capacitive electrode 107 may be formed or cut to a size that is slightly smaller than the overall size of the leaf member. The capacitive electrode 107 may be glued, adhered, or otherwise positioned between two layers of the non-conductive material to form the leaf member 106. The outer layer of the non-conductive material may be relatively thin, while the inner layer of the non-conductive material may be relatively thick. In the case of the sleep lamp 100, the relatively thin outer layer allows the leaf member 106 to be used as a capacitive touch plate, and the relatively thick inner layer may provide for mechanical mounting and structural stability. However, in some embodiments where structural stability is of less concern, the inner layer may also be formed from, in whole or in part, from a relatively thin layer, allowing for use as a capacitive touch plate from either side.
[0046]When forming the leaf member 106, the capacitive electrode 107 is positioned between the two layers of non-conducting material, becoming encased. In some embodiments, the capacitive electrode 107 is sized smaller than the non-conducting material layers, allowing an outer margin of the leaf member 106 to be a pure joint of the non-conducting material, which is virtually invisible once finished. In an alternate embodiment, the capacitive electrode 107 may be larger than the non-conductive layers, allowing the conductive material to overhang the edges of the non-conductive layers. The conductive material may be trimmed flush with the edges of the non-conductive layers after adhesion is complete.
[0047]The non-conductive material may be any material that does not conduct electricity, such as wood, plastic, ceramic, or other non-conductive materials. In particular, the non-conductive material is preferably a sound dampening material or a material designed not to emit sound when contacted (e.g., by a user). In particular, wood and plastic may provide sound dampening characteristics in addition to their non-conductive properties. A thickness of the outer non-conductive layer of the leaf member 106 may be set such that the non-conductive touch layer is thin enough to provide capacitive coupling between the conductive layer (e.g., the capacitive electrode 107) and a human body in physical contact with the outer layer.
[0048]An adhesive may be used to glue the thin, outer non-conductive layer to the inner non-conductive layer. In some embodiments, the adhesive may be used to adhere the outer layer to the inner layer through the porous fabric, cloth, mesh, foil, or metalized plastic sheet (such as, but not limited to, aluminized mylar). In addition to the conductive layer, one or more conductive connection parts may be disposed between the non-conductive layers. The conductive connection parts may include, for example, wire, metal coated thread, conductive fabric, conductive epoxy traces, metal pins, metal plates, Indium-Tin-Oxide coated plastic parts, or any other mechanism to contact the conductive electrode layer and/or to bring the connection points to a more mechanically stable portion of the electrode, for connection to an electronic device, such as a capacitive touch controller or microcontroller, discussed in greater detail below.
[0049]In some embodiments, The entire sandwich of materials that make up the leaf member 106 may be glued together under compression. Gluing the assembly under compression may help to promote homogeneous flow of the adhesive to more completely adhere the porous fabric to the non-conducting layers. Alternatively or additionally, the compression may help to deflect the wood around thicker areas, such as the contact points, where the thickness of the entrapped objects may be greater than the thickness at areas where only the fabric is present.
[0050]In embodiments, there may be multiple contacts within each leaf member 106, in order to allow for robustness if some contacts fail to produce low enough electrical resistance. Additionally, multiple contact points allow for the electrical testing between all combinations of points, allowing for a mapping of resistances across those distances, which may serve as a quality control measure.
[0051]The specific combination of a thin dielectric or non-conductive layer (e.g., wood veneer), a porous fabric of high density but thin overall thickness, an adhesive (e.g., wood glue), and a process to glue under compression, allows for a reliable capacitive electrode 107 encased in a non-conductive material, which may be an aesthetic and organic material such as wood. Other materials such as paper, fiberglass, plastic, and even other fabrics may be used in this method.
[0052]The housing 102 may include a diffuser 108. The diffuser 108 may be a thin layer that allows light to escape the lamp 100. The diffuser 108 may be retained by the frame members 104. In embodiments, the diffuser 108 may be formed from a thin material that allows at least some light to pass through (e.g., a translucent or transparent material). In some embodiments, the diffuser 108 may be formed from a wood veneer material that allows light to pass through the veneer. The diffuser 108 may optionally include one or more backing layers. Each backing layer may provide added structural support and/or additional optical properties. The diffuser 108 may optionally include one or more splines to support the diffuser.
[0053]The diffuser 108 may have various optical properties. In some embodiments, the diffuser 108 may serve as a filter, helping to limit light escaping from the sleep lamp 100. For example, the diffuser 108 may help to prevent light having certain wavelengths from being emitted by the sleep lamp. As a particular example, the diffuser 108 may help to prevent light having a wavelength in the range of about 480-490 nm from being emitted by the sleep lamp. As another particular example, the diffuser 108 may help to prevent all light from being emitted by the sleep lamp, with the exception of light having wavelengths in the range of 620-650 nm or greater (e.g., all light having a wavelength greater than 620 nm). Light having these wavelengths does not promote wakefulness during normal sleep time, but provides sufficient illumination to see the area surrounding the sleep lamp 100.
[0054]In some embodiments, the light created (e.g., emitted) by the sleep lamp 100 may be uncollimated light as an illumination device. Accordingly, the diffuser may be illuminated in a substantially even manner. Alternatively, the sleep lamp 100 may emit collimated light (e.g., using one or more lasers and/or focused light emitting diodes). In cases where the sleep lamp produces collimated light, the diffuser 108 may be illuminated by the collimated light to create vector images in the diffuser, or take a projected, focused pixel array to act as a screen for producing an image.
[0055]In some embodiments, the diffuser 108 may optionally be used as a sound amplifying surface (e.g., a speaker) in addition to a light diffuser. In particular, a small piezoelectric transducer may be attached to the diffuser 108. When driven with an audio signal, the vibration of the piezoelectric transducer causes the diffuser 108 to vibrate. The diffuser 108 may vibrate along its length, amplifying the audio signal from the piezoelectric transducer. Unlike a conventional speaker cone, which is designed to project sound primarily in one direction, with expanding scope, the diffuser 108 may project sound outward in directions normal to the flat surface of the diffuser and in a directional manner, such that volume of the audio signal is considerably lower in the side-ward directions than in directions substantially normal to at least a portion of the diffuser 108.
[0056]The housing 102 may include a cup support member 110. The cup support member may provide a support for the frame members 104. The cup support member 110 may be formed such that the sleep lamp 100 remains stable when a user interacts with (e.g., touches) the lamp. The cup support member 110 is preferably formed from a material similar to that used to form the frame members 104.
[0057]The housing 102 may include a base 112. In embodiments, the base 112 may be configured to receive one on more cables (e.g., one or more power cables for providing power to the sleep lamp 100, one or more data transfer cables, etc.). The housing 102 may include a set of feet 114 that protrude from the base 112 to contact a surface on which the sleep lamp rests. The feet 114 may be rubberized to help prevent the sleep lamp from sliding on the surface when interacted with (e.g., touched) by the user, and to help absorb shock in response to a user interacting with (e.g., touching) the lamp 100, thereby damping sound produced by the sleep lamp or interaction therewith by the user. The feet 114 may be designed to help damp vibrations and/or minimize noise created by actuation of the lamp 100 by a user.
B. Electrical Components
[0058]In embodiments, a sleep lamp may include electrical components for operation. In a first form, the sleep lamp may serve as a light emitting device, providing illumination that does not activate the melanopic response in users. In a secondary, more complex form, the sleep lamp may include some advanced features, beyond those included in the first form, as described below.
[0059]FIG. 2A illustrates a schematic view of first sleep lamp configuration 200. The sleep lamp 200 may include a control module 202, a lamp 204, and a control point 206. In embodiments, the control module 202 and the lamp 204 may be connected to one another, and to the control point 206, by electrically conductive wires.
[0060]The sleep lamp 200 may include a control module 202. In embodiments, the control module 202 may be electrically connected to the control point 206 (e.g., the leaf members 106 of FIG. 1) on a housing of the edge device. The control module 202 may enable operation of the sleep lamp 200 as a capacitive touch lamp. For example, the control module 202 may initially cause the lamp 204 to be in an “off” or unpowered state. Actuation of the control point 206 may cause the controller 202 to power the lamp 204 in a “dim” operating state; a first subsequent actuation of the capacitive touch control may cause the controller to power the lamp in a “brighter” operating state; and a second subsequent actuation of the capacitive touch control may cause the controller to power the lamp in a “brightest” operating state. Thereafter, a third subsequent actuation of the capacitive touch control may cause the controller 202 to return the lamp 204 to the “off” operating state. In this way, the controller 202 may serve as a brightness control for the lamp 204. While the above description illustrates a controller 202 configured to provide three brightness settings (in addition to an “off” setting), those of skill in the art will recognize that more or fewer brightness settings are possible without departing from the scope of the invention.
[0061]The sleep lamp 200 may include a lamp 204. In some embodiments, the lamp 204 may take the form of one or more light emitting diodes, one or more laser emitters, and/or any other source of collimated light. Additionally or alternatively, the lamp 204, may include a base socket for receiving a bulb, such as an incandescent light bulb, fluorescent light bulb, LED light bulb, and/or any other source of uncollimated light. In some embodiments, the lamp 204 may include a standard Edison screw base for receiving a bulb, and a bulb sized to mate with the selected base. As a particular example, the lamp 204 may include a 12-millimeter Edison screw base (e.g., an E12 base) to accept a candelabra bulb such as a C7 incandescent bulb or C35 LED bulb (or any E12 socketed bulb that fits the base). As another particular example, the lamp 204 may include an E26.E27 socket to accept an alternate type of bulb such as a T45 bulb (or any such bulb that fits). Other socket types are possible, with the corresponding bulb type.
[0062]FIG. 2B shows a schematic view of second sleep lamp configuration 250. The digital operating edge device 250 may include a microphone 252, one or more sensors 254, a processor 256, a memory 258, a time reference device 260, a transceiver 262, a light 264, and/or an audio amplifier 266. In embodiments the second edge device 250 is an advanced edge device that may be configured to send data to and/or receive data from a centralized server.
[0063]The sleep lamp 250 may include a microphone 252. The microphone 252 may be used to receive sound and/or measure sound intensity in the environment surrounding the sleep lamp 250. The microphone 252 may be, for example, a MEMS microphone, a piezoelectric microphone, an electret condenser microphone, or any other transducer capable of converting sound waves to an electrical impulse.
[0064]The sleep lamp 250 may include one or more sensors 254 instead of or in addition to the microphone 252. In embodiments, the one or more sensors 254 may collect ambient environmental data relating to the environment surrounding the user. As particular examples, the one or more sensors 254 may include a camera, a temperature sensor, an air pressure sensor, and/or a lux meter (e.g., one or more photodiodes). Various sensors 254 may be used to measure ambient environmental data that may affect user health or behavior.
[0065]The second edge device 250 may include a processor 256 connected to the microphone 252 and/or the one or more sensors 254. The processor 256 may be capable of analyzing the data received from the microphone 252 and/or the one or more sensors 254. In some embodiments, the analysis may optionally include using machine learning to analyze the data. That is, the inputs may be provided to a trained machine learning model capable of categorizing the received data. The machine learning model may be stored locally, at the sleep lamp 250, and/or at a server in communication with the sleep lamp. Alternatively or additionally, the analysis may include a threshold analysis and/or an algorithmic analysis instead of or in addition to the machine learning. The processor 256 may produce, as output, a signal for controlling the lamp 264 and/or the audio amplifier 266 based on the processed input signals from the microphone 252 and/or the sensors 254.
[0066]As an example, the processor 256 may analyze data from the microphone 252 to determine whether sounds in the room are indicative of sleep (e.g., snoring) or wakeful activities (e.g., talking, crying etc.). As another example, the processor 256 may analyze data from a camera among the sensors 254 to determine if there is movement in the vicinity of the sleep lamp 250. In some embodiments, the processor 256 may produce, as output, a signal for activating the lamp 264 based on the processed input sensor signals to illuminate the area so that a caretaker can see to check on a crying baby. In some embodiments, the processor 256 may produce, as output, a signal for activating the audio amplifier 266 based on the processed input sensor signals to produce soothing sounds in an effort to put a user to sleep.
[0067]The second edge device 250 may include a memory 258. The memory 258 may be a random-access memory (RAM) device, such as a flash memory. The memory 258 may be accessible by the microphone 252, the one or more sensors 254, the processor 256, the transceiver 262, and/or any other component of the sleep lamp 250.
[0068]The sleep lamp 250 may include a time reference device 260. In some embodiments, the time reference device 260 may include a real time clock (RTC). The time reference device 260 allows the sleep lamp 250 to determine a current time of day and a current date. Based on the date, the sleep lamp may also determine a current season. Determining both time of day and season may be important for circadian rhythms and improving sleep health. In other embodiments (e.g., where no RTC is present), the time reference device 260 may be a remote time source, or may correspond to a user input setting the time and date, wherein the processor 256 may serve as the time reference device 260 by counting clock cycles. In embodiments, the time reference device 260 may serve as an input to the processor 256 for use in calculating one or more output signals.
[0069]The sleep lamp 250 may include a transceiver 262 for communication with other devices. The transceiver 262 may be configured to send and receive signals. The signals may include wireless signals, such as radio frequency (RF) signals (including sub-gigahertz signals) and/or Internet of Things (IoT) radio frequencies (e.g., those set aside for industrial, scientific and medical (ISM) purposes), signals compliant with the International Electrical and Electronics Engineers (IEEE) 802.11 standards, signals compliant with Bluetooth (e.g., IEEE 802.15.1) standards, signals compliant with ZigBee (IEEE 802.15.4) standards, or any other wireless signals useful for communicating data between devices. Additionally or alternatively, the signals may include data communication signal suitable for wired communication (e.g., via IEEE 802.3 communication standards). In embodiments, the transceiver 262 may facilitate transmission of data (e.g., data received from the microphone 252 and/or the one or more sensors 254) to a server. In some embodiments, the transceiver 262 may be in communication with an external time source as part of the time reference device 260.
[0070]The second edge device 250 may include a light (or lamp) 264 for illuminating an area surrounding the second edge device. The lamp 264 may comprise one or more light emitting diodes (LEDs), such as one or more surface mounted device (SMD) LEDs. The lamp 264 may emit light having wavelengths of more than 580 nm. For example, the lamp 264 may emit light at least having wavelengths in the range of 620-650 nm, or light having wavelengths greater than 620 nm. Light having these wavelengths does not promote wakefulness during normal sleep time, but provides sufficient illumination to see the area surrounding the second edge device 250. In some embodiments, the lamp 264 may emit light having a broad spectrum of wavelengths (e.g., white light). In some embodiments, the lamp 264 may take the form of one or more light emitting diodes, one or more laser emitters, and/or any other source of collimated light. Additionally or alternatively, the lamp 264, may include a base socket for receiving a bulb, such as an incandescent light bulb, fluorescent light bulb, LED light bulb, and/or any other source of uncollimated light. In some embodiments, the lamp 264 may include a standard Edison screw base for receiving a bulb, and a bulb sized to mate with the selected base. As a particular example, the lamp 264 may include a 12-millimeter Edison screw base (e.g., an E12 base) to accept a candelabra bulb such as
