Abstract

The invention discloses an LED head lamp capable of automatically adjusting illumination. The LED head lamp comprises a base, an LED head lamp body, a bridle, a battery, a photosensitive sensor, a pulse width modulator and a switch. The LED head lamp body is connected with the battery and fixed to the base. The two ends of the bridle are connected with the base and the battery respectively. The battery is located right behind the LED head lamp body. The photosensitive sensor is fixed to the middle of the bridle and connected with the pulse width modulator. The pulse width modulator is embedded into the base and connected with the LED head lamp body. The switch is arranged on the battery. In this way, according to the LED head lamp capable of automatically adjusting illumination, the illumination can be enhanced based on environment illumination so as to highlight a target, meanwhile, the illumination of the black environment can be supplemented based on environment light so as to control luminous flux, the illumination can be sensitively controlled with no operation, and the LED head lamp is flexible and convenient to use, intelligent and practical.

Description

technical field [0001] The invention relates to the field of lamp manufacturing, in particular to an automatic dimming LED headlamp. Background technique [0002] Headlights are lighting tools commonly used by field workers, miners and other special industry personnel. They are convenient and flexible to use, but the brightness of the light source cannot be automatically controlled or even quantitatively controlled manually, which affects work efficiency and causes secondary problems under special environmental conditions. . Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an automatic dimming LED headlight, which can enhance the illuminance based on the ambient light brightness to achieve the purpose of protruding the target object, and can also use the ambient light as a benchmark to supplement the illuminance in a dark environment to achieve For the purpose of controlling luminous flux, illuminance control is...
