LED light source color temperature control device manufacturing method

A LED light source color temperature control device

technical field

1. The utility model relates to the technical field of LED light sources, in particular to a color temperature control device for LED light sources.

Background technique:

2. LED color temperature is to change the proportion of different lights. Increase the red light, the color temperature becomes warmer, and increase the blue light, the color temperature becomes colder. Adjust the brightness, change the current flowing through the led, the larger the current, the brighter it will be. Otherwise, it's darker. The adjustment of the current is realized by changing the pwm.

3. When the LED light source controls the color temperature, the controller will generate heat. If the heat cannot be discharged in time, the heat will cause loss to the control device, thereby reducing the service life of the control device.
