In some embodiments, mounting plate 215 may be attached to bottom-portion 201 and/or to LED chip holder 213. In some embodiments, mounting plate 215 may be attached to the (top) closed end of bottom-portion 201 via one or more fasteners 241. In some embodiments, mounting plate 215 may be attached to LED chip holder 213 via one or more fasteners 241.
[0108]Continuing discussing FIG. 2A, FIG. 2B, and FIG. 2C, in some embodiments, LED chip 211 may be configured to emit light when appropriately energized from a connected electrical power source. In some embodiments, LED chip 211 may be operatively connected to an electrical power source (e.g., via electric power cable 161). In some embodiments, LED chip 211 may comprise one or more LEDs as well as additional circuitry. In some embodiments, LED chip 211 may be an off the shelf component. In some embodiments, light emitted by LED chip 211 may of a predetermined characteristic, such as, but not limited to, brightness, softness, wavelength, color, temperature, duration, portions thereof, combinations thereof, and/or the like. In some embodiments, LED chip 211 may be configured (e.g., positioned) to emit light downwards and through fixed (and closest) lens 221 and through telescopic lens 151. In some embodiments, LED chip 211 may be closer to fixed lens 221 than to telescopic lens 151. In some embodiments, a distance between LED chip 211 and fixed lens 221 may be fixed; whereas, a distance between LED chip 211 and telescopic lens 151 may vary within a predetermined range. In some embodiments, LED chip 211 may be attached to LED chip holder 213. In some embodiments fixed lens 221 and LED chip 211 may be disposed on different sides/surfaces of LED chip holder 213. In some embodiments fixed lens 221 and LED chip 211 may be attached to different/opposing sides/surfaces of LED chip holder 213.
[0109]Continuing discussing FIG. 2A, FIG. 2B, and FIG. 2C, in some embodiments, LED chip holder 213 may be attached to one or more of: LED chip 211, fixed lens 221, and/or mounting plate 215. In some embodiments, LED chip holder 213 may be mostly (substantially) disc like with a relatively large central hole to accommodate at least portion of LED chip 211 that has one or more LEDs. In some embodiments, LED chip holder 213 may have additional smaller hole(s) disposed around the relatively large central hole configured for receiving one or more fastener(s) 241. In some embodiments, disposed on opposite sides of the relatively large central hole may be two regions of rectangular cutouts.
[0110]Continuing discussing FIG. 2A, FIG. 2B, and FIG. 2C, in some embodiments, fixed lens 221 may be attached to a bottom side of LED chip holder 213. In some embodiments, fixed lens 221 may be attached to a bottom side of LED chip holder 213, via a snap fit, a friction fit, an interference fit, fastener 241, portions thereof, combinations thereof, and/or the like. In some embodiments, a bottom of fixed lens 221 may be convex (e.g., bulging downwards). In some embodiments, fixed lens 221 may be mostly (substantially) optically transparent (translucent) so as to permit passage of most of the light emitted from LED chip 211 through fixed lens 221. In some embodiments, when downlight module with extendable lens 100 may be in its assembled configuration, fixed lens 221 may have a fixed, static, non-variable, and/or non-moving relationship with LED chip holder 213, LED chip 211, mounting plate 215, heat sink module 101 (and all of its parts/regions), top (inner) cylinder 231, telescopic holder 121, and/or fastener(s) 241. In some embodiments, when downlight module with extendable lens 100 may be in its assembled configuration, fixed lens 221 may have a dynamic, variable, and/or moving/movable relationship with telescopic lens 151 and/or bottom (outer) telescopic cylinder 141 (within a predetermined range of motion). In some embodiments, fixed lens 221 may be mostly or partially located within internal cavity 203 of bottom-portion 201 and entirely located within bottom (outer) telescopic cylinder 141. In some embodiments, a bottom most portion of fixed lens 201 may extend down and beyond where internal cavity 203 ends (see e.g., FIG. 2C).
[0111]Continuing discussing FIG. 2A, FIG. 2B, and FIG. 2C, in some embodiments, top (inner) cylinder 231 may be substantially (mostly) hollow cylindrical member, that may be substantially (mostly) open at both axial terminal ends. In some embodiments, top (inner) cylinder 231 may be fixedly attached to bottom-portion 201. In some embodiments, outside threading on top (inner) cylinder 231 may be attached to inside threading of bottom-portion 201. In some embodiments, top (inner) cylinder 231 towards its top end may comprise a top flange 233. In some embodiments, top flange 233, around its outside periphery, may comprise outside threading. In some embodiments, this outside threading of top flange 233 may be complimentary attach to inside threading of bottom-portion 201. In some e
