调节可调光LED照明系统中的色温
摘要：
本申请公开了一种可以模拟白炽灯泡的表现的LED照明系统，例如可调光的LED灯。不同颜色的LED串可以被连接到调节LED照明系统所产生的光的总体强度的单个LED驱动器的输出。LED照明系统的颜色可以由电路控制，例如一个或多个开关，该电路在LED串之间分配电流以在光强度变化时改变LED照明系统发出的光的色温。
摘要（英）：

A LED lighting system, such as a dimmable LED lamp, that may simulate the performance of an incandescent bulb. LED strings of different colors are connected to the output of a single LED driver that regulates an overall intensity of light produced by the LED lighting system. The color of the LED lighting system is controlled by circuitry, such as one or more switches, that allocates current between the LED strings to change the color temperature of light emitted by the LED lighting system as the light intensity changes.
