LED laser pen lamp

Abstract

The invention relates to an LED laser pen lamp which comprises a pen body. A laser module is fixedly arranged in the pen body. A lamp cap is fixedly arranged at the position of an opening of the top of the pen body. A control circuit board is arranged in the pen body. An integrated COB light source is fixedly arranged on one side of the control circuit board. A light transmitting area is arrangedat the position, corresponding to the COB light source, of the pen body, and a transparent lampshade is further fixedly arranged at the position, corresponding to the light transmitting area, of the pen body. A battery is further arranged in the pen body, the battery supplies power to the integrated COB light source and the laser module through the control circuit board, and the control circuit board controls the integrated COB light source to work through a constant-current driving circuit. The control circuit board controls the laser module to work through a laser driving circuit. A DC socket is further fixedly arranged at the bottom of the pen body, the DC socket is used for being connected with an external power source, and the battery is charged through a charging circuit of the control circuit board.

Description

technical field [0001] The invention relates to a laser pen light, in particular to an LED laser pen light. Background technique [0002] LED lamp is an energy-saving and high-efficiency light source. When electrons pass through a semiconductor chip encapsulated in epoxy resin, negatively charged electrons and positively charged holes on the chip recombine and disappear while generating photons. The traditional auto repair industry usually uses incandescent and fluorescent lamps. Incandescent lamps and fluorescent lamps are fragile, large in shape, inconvenient to use and carry, and low in waterproof level, so they cannot be used outdoors. [0003] Due to many advantages such as energy saving, environmental protection, light control, solidification, and long life, LED lights have been widely used in various fields such as urban public lighting, office and indoor and outdoor lighting. Traditional laser pointers have single functions and single use scenarios. Traditional las...
