| 摘要 |
The invention relates to an optical system for lighting applications, fundamentally formed by a light source and a reflector, essentially with axial symmetry, the inner face thereof containing a complex surface formed by a plurality of microstructures with the particularity of being arranged in a specific distribution, according to a concrete parameterisation, and with a particular division of the surface space (tessellated), which allows a suitable destruction of the image projected from the actual light source, and provides a uniform and well-defined pattern of the projected light. The reflector can have an edge-free inner surface at the join between adjacent micro-structures, such that it reduces the optical losses and the light dispersion. There can also be a local regulation of the form and orientation between adjacent micro-structures by means of deformation, translation and/or rotation, which allows better control of the projected light and enables light patterns without axial symmetry. The invention also relates to a novel method for the construction of the complex inner surface of the reflector, allowing the novel technical characteristics mentioned, such that it extends and improves some current limitations. |
