摘要：
A method for producing a luminaire housing (100) on an additive manufacturing system includes selecting a luminaire housing (100) base shape from which a data file of a first convex polyhedral model is built, rescaling the first convex polyhedral model into a larger convex polyhedral model, filling the larger convex polyhedral model with multiple versions of the first convex polyhedral model, separating larger convex polyhedral shape (710) model into structural unit shape, and providing the data file containing the structural unit shapes to the additive manufacturing system. In some implementations an interior volume of the larger convex polyhedral shape (710) model can be cleared of portions of first convex polyhedral model. The method includes the additive manufacturing system producing one or more structural units (200,300) based on the structural unit shapes described in the electronic data file. A non-transitory computer readable medium, and a luminaire housing (100) including a light source (500,520) are described.
技术问题语段：
The patent text is about additive manufacturing, also known as 3D printing, which is a process to create 3D objects using computer control. The process involves creating a digital file of the object using geometrical data, and then slicing it into thin layers to build up the object using various materials like thermoplastics, rubbers, clays, ceramic, polycarbonate, photopolymer, and metal alloys. The technical problem addressed by the patent is how to use additive manufacturing to produce complex 3D objects using these technologies and materials.
技术功效语段：
The patent describes a method for creating a luminaire housing using additive manufacturing technology. This technology allows for the creation of complex objects that cannot be produced using conventional manufacturing methods. The process involves creating parts using a computer program and then combining them to create the final housing. The design of the housing is based on a digital file that describes its surface geometries. The process can be time-consuming, but it allows for the creation of objects that would be difficult or impossible to produce using other methods. The patent also describes the use of different materials and technologies for additive manufacturing, such as thermoplastics, rubbers, clays, ceramic, and metal alloys.
权利要求：
1. A method for producing a luminaire housing (100) on an additive manufacturing system, the method comprising: selecting a base element (705) for the shape of the luminaire housing; building, in an electronic data file, a first model of a convex polyhedral shape (710) using the base element as a building block; rescaling the first convex polyhedral shape model into a second model of a convex polyhedral shape (715), the second convex polyhedral shape model being larger than the first convex polyhedral shape model; filling the second convex polyhedral shape model with multiple versions of the first convex polyhedral shape model; separating the second convex polyhedral shape model into structural unit shapes; and providing the electronic data file containing the structural unit shapes to the additive manufacturing system.
2. The method of claim 1, including producing by the additive manufacturing system one or more structural units (200, 300) based on the structural unit shapes described in the electronic data file.
3. The method of claim 2, including assembling the structural units to form the luminaire housing.
4. The method of any preceding claim, including the steps of: analyzing the filled second convex polyhedral shape model to determine an interior volume of the model that is to be cleared of a predefined center shape (720); and removing from the second convex polyhedral shape portions of the multiple versions of the first convex polyhedral shape model that occupy the same volume as the predefined center shape.
5. The method of claim 3, including positioning a light source (500) within an interior volume of the luminaire housing.
6. The method of claim 3, including positioning a light emitting diode light source along a sidewall of one or more of the structural units.
7. The method of claim 4, including selecting the center shape size based on a predetermined thickness of the luminaire housing.
8. The method of any preceding claim, wherein the convex polyhedral shape is a truncated icosahedron shape.
