Abstract

The present invention discloses an LED automatic dimming system. A controller module is electrically connected to the LED constant current driving module, and the other end is electrically connected to an A / D converter. The LED constant current driving module is electrically connected to a car LED headlamp. The A / D converter is electrically connected to a signal amplifier. A distance sensor is electrically connected to the signal amplifier, and an ambient light sensor is electrically connected to the signal amplifier. The LED automatic dimming system is based on a distance sensor, a disadvantage based on a light intensity sensor in the prior art can be effectively improved, and the visual interference of the car headlamp can be effectively reduced regardless of whether the headlamp of a car in front of a driven car is opened or not or regardless of pedestrians.

Description

technical field [0001] The invention relates to the field of LED dimming systems, in particular to an LED automatic dimming system. Background technique [0002] Along with more and more traffic accidents that occur because of the unreasonable setting of automobile headlights, people pay more and more attention to the dimming technology of automobile headlights. Existing patent CN203618181U provides a kind of automatic dimming system of automobile headlights, including automobile headlights, light intensity sensor module, controller module, dimming drive module; the light intensity signal detected by light intensity sensor module is input to Controller module; the controller module analyzes and processes the input light intensity signal, and then inputs the control signal to the dimming drive module, and the dimming drive module controls the brightness of the automobile headlight. This technology can avoid visual disturbance caused by two cars turning on their headlights at...
