Claim of US Patent No. 10,893,587

1. An LED lighting device or LED lamp comprising:a plurality of first LED packages each configured to emit light having a first configurable light quality;
a plurality of second LED packages each configured to emit light having a second configurable light quality;
at least one driver circuit configured to condition an electrical current provided to at least one of (a) a first group of the plurality of first LED packages or (b) a second group of the plurality of second LED packages; and
a control unit configured to operate the first group of the plurality of first LED packages, via the at least one driver circuit, and the second group of the plurality of second LED packages, via the at least one driver circuit, the first group of the plurality of first LED packages and the second group of the plurality of second LED packages operated independently of one another, the control unit being: (a) in communication with a sensor located in a space, the LED lighting device or LED lamp also being located in the space, and (b) configured to:
determine whether the LED lighting device or LED lamp is in a sensor adjustment mode or in a non-adjustment mode,
when the LED lighting device or LED lamp is in the non-adjustment mode, not adjust the operation of the plurality of first LED packages and the plurality of second LED packages in response to receiving a sensor signal from the sensor, and
when the LED lighting device or lamp is in the sensor adjustment mode, (i) receive a sensor signal from the sensor, (ii) process the sensor signal, (iii) determine an adjustment to the operating light qualities of the LED lighting device or LED lamp based on the processing of the sensor signal and one or more goal light qualities corresponding to the space, and (iv) adjust the operation of the plurality of first LED packages and the plurality of second LED packages in accordance with the determined adjustment such that a combination of (a) light emitted by the plurality of first LED packages and the plurality of second LED packages and (b) ambient light in the space provides lighting in accordance with the goal light qualities, wherein the adjustment comprises modifying (a) a number of the plurality of first LED packages in the first group, or (b) a number of the plurality of second LED packages in the second group to adjust one or more light qualities of light emitted by the LED lighting device or LED lamp.
