Embodiment Construction
[0010] The present invention will be further described below in conjunction with the drawings and specific implementations:
[0011] See figure 1 , The present invention relates to an LED lighting adjustment device, and its preferred embodiment includes a controller with a number of PWM output terminals, a number of digital-to-analog converters, and a number of LED analog drivers. Among them, the PWM output, the digital-to-analog converter and the LED analog The drives have a one-to-one correspondence.
[0012] The controller is used to output several PWM control signals through several PWM output terminals; each digital-analog converter is used to convert the corresponding one PWM control signal into a linear analog control signal; each LED analog driver according to the corresponding linear analog control signal Control LED lights.
[0013] In this way, the present invention controls the LED lamp by converting the PWM control signal into an analog signal, which can simultaneously...
