Abstract (en)
[origin: CN108361652A] A lighting device (DE) comprises at least one light source (SL) capable of generating photons and a mask (M) able to let the photons generated to pass through at predefined locations. The mask (M) comprises a front face (FV), facing outwards and provided with three-dimensional elements (ET) participating together in a predefined photometric function and each having a general shape diamond tip defined by at least two contiguous opaque facets (FOj) and at least two contiguous opaque facets (FTj). The at least two opaque facets are inclined relativley to each other. Each of the two transparent facets (FTj) allows one of the opaque facets (FOj) to extend to the contiguous three-dimensional elements (ET) in an inclined manner at one of the predefined locations.
