Abstract

The invention discloses an LED illumination control method and device applied to a lantern including an LED and a microcontroller. The method in the embodiment of the present application comprises obtaining the brightness level of the LED and the color change minimum unit in a full color wheel; controlling the brightness of the LED according to the brightness level; and adjusting the duty ratio ofa PWM signal for controlling three colors RGB in the LED according to the color change minimum unit to control the color change speed of the LED and achieve a dimming and speed regulation purpose.

Description

technical field [0001] The invention relates to the field of lighting control, in particular to a method and device for controlling light emission of a light emitting diode. Background technique [0002] The application of lighting is very extensive. In homes, shopping malls, stages, and even many public places, there are all kinds of lighting, and the forms of display are also diversified. In most cases, the colorful lights used as ambient lights also play an indispensable role, and most of the colored lights are composed of RGB LEDs, which originate from the principle of three primary color mixing of visible light in nature, and can be controlled by PWM through MCU. To achieve different ratios of RGB mixed with each other to get the required color. [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the above related technologies: at present, most RGB LED products can display multiple static col...
