  • Patent number: 11291089
    Abstract: According to one embodiment, a lighting apparatus includes light sources, each light source emitting a different electromagnetic radiation having a different color temperature when turned ON. A controller turns ON and OFF each light source such that each electromagnetic radiation of each light source comprises a series of pulses. The controller alternate between turning ON each of the light sources with a speed sufficient to cause a perception of mixing the electromagnetic radiations of the light sources, thereby causing an appearance of a perceived light having a perceived color temperature different from the color temperatures of the light sources. To ensure that only one of the light sources is ON at a time, the controller waits a predetermined time between turning OFF a light source and turning ON a subsequent light source. The predetermined time is based on both a time for a light source of the plurality of light sources to turn OFF and a variable buffer time.

  • Patent number: 10728976
    Abstract: A lighting apparatus may include light sources. Each light source may emit a different electromagnetic radiation having a different color temperature when turned ON. The lighting apparatus may include a voltage source providing power to the light sources and a controller. The controller may turn ON and OFF each light source such that each electromagnetic radiation of each light source comprises a series of pulses. The controller may alternate between turning ON each of the light sources with a speed sufficient to cause a perception of mixing the electromagnetic radiations of the light sources, thereby causing an appearance of a perceived light having a perceived color temperature different from the color temperatures of the light sources. To ensure that only one of the light sources is ON at a time, the controller may wait a predetermined time between turning OFF a light source and turning ON a subsequent light source.
