Abstract

The invention relates to a control device of a light-control LED automobile headlamp. The control device comprises a voltage stabilization circuit, a pulse signal circuit and a constant-current driving circuit, wherein an input end of the voltage stabilization circuit is connected with a DC voltage source, an output end of the voltage stabilization circuit is connected with an input end of the pulse signal generation circuit, an output end of the pulse signal generation circuit is connected with an input end of the constant-current driving circuit, and an output end of the constant-current driving circuit is connected with the automobile headlamp. By the device, the luminous intensity of the automobile headlamp is controlled to be automatically adjusted with ambient illumination intensity, and an energy source is favorably saved. The device can also be applied to other lighting occasions such as road / plaza lighting if the device is changed slightly, and has a wide application prospect.

Description

technical field [0001] The invention relates to lighting, electronic technology, and electrical control devices, in particular to a light-controlled LED automotive headlight control device that automatically adjusts luminous intensity with changes in ambient light intensity. Background technique [0002] With the maturity of LED technology, it is the general trend for LED lighting fixtures to replace traditional lighting fixtures, and the same is true for LED lighting fixtures used as automotive lighting fixtures. In the early stage, LED lamps were only used as small lights for cars. For example, European legislation stipulates that all models on sale must be equipped with LED width indicators for driving safety. In recent years, there are more and more car models that use LED lamps as lighting fixtures including headlights, including famous models such as Mercedes-Benz and Audi. [0003] The headlights (including the high beam and the low beam) on the current automobiles a...
