Abstract
Systems, software, and methods are provided for efficient, dynamic lighting control. In an embodiment, a two-channel LED lighting system is dynamically controlled to emulate dimming of an incandescent fixture. In an example, a lighting fixture may include red, green, blue, and white emitting LED modules. The lighting fixture may be controlled such that it produces generally white light from about 2150K candle light color to 5500K daylight white color with only 4 LEDs. Furthermore, the white LED may be controlled such that the white LED CRI is approximately 95 to ensure optimal results when mixed with red and green. In another embodiment, a dynamic two-channel LED lighting system is controlled to emulate dimming of an incandescent fixture. Specific dimming protocol can allow for efficient dimming which helps minimize the height of a linear light fixture and maintain diffusion with multiple colored point sources at minimal pitch.
