Abstract:
A low profile lighting module. Devices according to this disclosure can produce a uniform light intensity output profile, limiting the perceived appearance of individual point sources, from direct lighting modules comprising several light emitting diodes. Individual lighting device components are disclosed that can contribute to this uniform profile, including: primary optics, secondary optics, and contoured housing elements. These components can interact with and control emitted light, thus adjusting its pattern. These components can alter the direction of emitted light, providing a more uniform light intensity over a wider range of viewing angle.
