Patent number: 10113714
Abstract: Apparatus and methods are described herein for lighting control. A lighting unit (100, 200, 300, 400, 500) may include a base (104, 204, 304, 404) adapted to be inserted into a socket (106, 206, 306) of a luminaire/lighting fixture. The lighting unit may include one or more light sources (108, 208, 308, 408, 508) to emit light at least in a first direction and one or more reflective elements (110, 210, 310, 410, 510, 610) arranged to define an aperture (112, 212, 312, 412, 512, 612) through which a first spatial portion (114, 214, 314, 414, 514) of the emitted light continues in the first direction, prevent a second spatial portion (116, 216, 316, 416, 516) of the emitted light from continuing in the first direction, and reflect at least part of the second spatial portion of the light in a second direction different than the first direction.
