  • Patent number: 10750598
    Abstract: Lighting systems and methods for lighting fixture location mapping, for example, using a combination of photosensing readings and/or other sensors to identify a correct mapping. These systems and methods may be used to resolve ambiguities that could not be resolved using other processes, such an auto-commissioning method that identifies more than one possible mapping of the lighting fixtures to spatial locations. Such ambiguities are typically found in floor plans that are symmetrical. The systems and methods of the present invention record and utilize environmental profiles, such as ambient lighting levels and occupancy patterns, to match lighting fixtures to their respective spatial locations and provide resolution to ambiguities in an auto-commissioning method that identifies more than one possible mapping of the lighting fixtures to spatial locations.

  • Patent number: 10736195
    Abstract: An electronic device comprising a matched filter to drive a LED module is disclosed. The matched filter receives an incoming rectangular pulse and outputs a modulated driving signal to drive the LED module. The optical output from the LED is captured by an optical sensor and converted to electrical signal for analysis. A decimation filter couples to the optical sensor in an effort of reducing sampling rate and quantization noise of the converted electrical signal. The modulated driving signal output from the matched filter keeps the LED current, thus LED light, matching the time-mirrored impulse response of the decimation filter to obtain or approach a theoretical maximum signal-to-noise (SNR) at a fixed amount of power.

  • 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.
