LENSES FOR COSINE CUBED, TYPICAL BATWING, FLAT BATWING DISTRIBUTIONS |
摘要 |
A lighting apparatus with uniform illumination distribution, according to various embodiments, can include a lens for area lighting. In one embodiment, the lens comprises a plurality of cross-sections identified by a thickness ratio defined at different angles. The thickness ratio is determined relative to the thickness of the cross-section defined at a center angle of the lens. In another embodiment, the lighting apparatus with uniform illumination distribution includes a lens having an inner surface and an outer surface. A profile of the inner surface and the outer surface is composed of a plurality of piecewise circular arcs defined with radii and circle centers. The lens is formed as a complex curve lens by joining the piecewise circular arcs of the inner surface and the outer surface. |
