Abstract
A color temperature fusion lighting apparatus includes a first light source with a first color temperature, a second light source with a second color temperature, and a driver circuit. The driver circuit operates the lighting apparatus in two modes. In the first mode, the driver circuit operates the lighting apparatus in a first linear combination of the first light source and the second light source, resulting in a first operating color temperature for the lighting apparatus. In the second mode, the driver circuit operates the lighting apparatus in a second linear combination of the first light source and the second light source, resulting in a second operating color temperature. Moreover, the driver circuit is configured to alternate the operation of the lighting apparatus between the first mode and the second mode at a frequency F between 35 to 45 Hz, resulting in a blended color temperature of the first operating color temperature and the second operating color temperature for the lighting apparatus.
