Abstract
A lighting apparatus includes a first light source with a first color temperature, a second light source with a second color temperature, and a control module. The control module operates the lighting apparatus in two modes. In the first mode, the control module operates the lighting apparatus in a first linear combination of two light sources, resulting in a first operating color temperature for the lighting apparatus. In the second mode, the control module operates the lighting apparatus in a second linear combination of two light sources, resulting in a second operating color temperature. The control module is configured to alternate the operation of the lighting apparatus between the first mode and the second mode at a frequency between 35 to 45 Hz, resulting in a blended color. Additional technical features a are introduced to minimize the light output difference of the first light source and the second light source.
