Description

technical field [0001] The invention relates to the technical field of LED driving, in particular to a Bluetooth color temperature LED driving power supply. Background technique [0002] With the development of new semiconductor light-emitting materials and the continuous improvement of manufacturing processes and the continuous improvement of high-power LED integrated driver chips, high-brightness and high-power light-emitting diode lighting sources have gradually entered daily life due to their advantages of high efficiency, energy saving, and environmental protection. Gradually replace incandescent lamps, fluorescent lamps, etc. as new light sources in the field of general lighting. In lighting, the correlated color temperature is generally used to measure the dyeability of white light, and it is measured by the Kelvin scale (K). The color temperature range of warm white light such as incandescent lamps and warm white fluorescent lamps is 2000-4100K, and the color tempera...
