Abstract:

An LED downlight provides a more evenly distributed light output. The LED downlight includes an LED light source, such as one or more LEDs, LED die packages, or LED chip on board modules, an upper reflector, a lower reflector disposed below the upper reflector, and a lens disposed between the upper reflector and the lower reflector. The lens includes several features that help disperse light emitted by the LED light source. The lens includes a diffusion element, such as a pigment, bulk scattering, prismatic, inlays, or another method for diffusing light through a lens. The lens is curved in a concave manner when viewed from the light source. The curve of the lens can be tangent to the physical cutoff of the lower reflector to more evenly distribute light emitted by the LED light source and to improve the visual effect of an evenly luminous lens.
