  • Patent number: 11259377
    Abstract: Certain aspects involve a lighting fixture including multiple de-saturated color LED groups and in which the color temperature and intensity of the generated light can be selectively modified. The lighting fixture is driven by a multi-channel driver that independently controls the multiple de-saturated color LED groups. In one example, the de-saturated color LED groups are made with the same Indium gallium nitride (InGaN) LED, as to maintain all electrical/thermal characteristics. The color temperature and intensity of the lighting fixture are adjusted by managing the intensity of each of the de-saturated color LED groups according to a lookup table or a formula describing the relationship between the intensities of the de-saturated color LED groups and the color temperature and intensity of the lighting fixture. Because de-saturated color LEDs are used in the lighting fixture, dynamic dimming or “warm dim” can be achieved to replicate the effect of an incandescent lamp.
