The LED luminance regulating device comprises an environment luminance self-detection module (2) and an LED drive module (3), wherein the environment luminance self-detection module (2) is used for detecting a luminance grade of an LED lamp bar module (1), a signal output end of the environment luminance self-detection module (2) is connected with a signal input end of the LED drive module (3), and a signal output end of the LED drive module (3) is connected with a signal input end of the LED lamp bar module (1). According to the LED luminance regulating device and the regulating method based on the LED self-sensing detection, self-property change of an LED lamp bar in an LED lamp bead working process is used for measuring an environment luminance change value, an external sensor is not required, and the fact that the lighting luminance of the LED lamp bar can be automatically regulated according to environment luminance is achieved. The LED luminance regulating device and the regulating method based on the LED self-sensing detection are good in real-time property, high in property cost ratio, high in stability, convenient to use and practical.

Description

technical field [0001] The invention is an LED brightness adjustment device and adjustment method based on LED self-sensing detection, which belongs to the innovative technology of the LED brightness adjustment device and adjustment method based on LED self-sensing detection. Background technique [0002] LED (Lighting Emitting Diode) lighting is LED lamp bead lighting, which is a semiconductor solid light emitting device. It uses a solid semiconductor chip as a light-emitting material. In the semiconductor, the excess energy is released through the recombination of carriers to cause photon emission, and directly emits red, yellow, blue, and green light. On this basis, using the principle of three primary colors, Adding fluorescent powder can emit light of any color such as red, yellow, blue, green, blue, orange, purple, white, etc. LED lighting products are lighting appliances manufactured using LEDs as light sources. [0003] Under the background of rising global energy ...
