An optical axis of the light emitted from each LED is orthogonal to the wiring board. The lens has a light emitting surface that controls distribution of the light emitted from each LED.

Abstract: A luminaire can comprise a housing that comprises a flat surface or platform. The platform can comprise one or more apertures. One or more light modules can be disposed in the aperture or apertures, so that each light module is set into the platform, for example. Each light module can be rotated within its aperture. Each light module can emit a pattern of illumination that is biased relative to its axis of light module rotation, for example. Accordingly, the illumination emitted by each light module can be aimed in various directions by rotating the light module. Adjusting the rotational orientation of each light module can thus control where the luminaire directs the illumination pattern.
