The color temperature adjustable led bulb light profile

     The color temperature adjustable led bulb light including a plurality of LED devices and controls the LED drive control device module. LED devices are LED devices with different color temperature, and based on the color temperature of the LED devices were divided into several groups. The drive control module controls the LED device of each group, one or more sets of the light-emitting light.
     The drive control module of the color temperature adjustable led bulb light includes LED dimming control circuit, where there are multiple color temperature control switch, each color temperature control switch connected to a set of LED devices group, used to control the current on-off of LED device group.
     This LED bulb driver circuit further comprises a power supply control module and a first micro-processing unit. A first output terminal of the power supply circuit is connected to LED dimming control circuit input terminal by the power control switch. A second output terminal of the power supply circuit is connected to the input terminal of the first micro-processing unit. The first PWM control signal micro processing unit connected to the output terminal of the power supply control switch for controlling the on-off state of the power control switch. The color temperature control signal output terminal of the first micro-processing unit circuit is connected to LED dimming control signal input terminal circuit are connected, used to control the color temperature control switch on-off.
