Technical background of LED laser pointer
The LED lamp is an energy-saving and efficient light source. When electrons pass through a semiconductor chip encapsulated in epoxy resin, the negatively charged electrons and the positively charged holes on the chip recombine and disappear while generating photons. The traditional car repair industry usually uses incandescent and fluorescent lamps. Incandescent lamps and fluorescent lamps are fragile, large in appearance, inconvenient to use and carry, and low waterproof level, so they cannot be used outdoors.The bottom of the pen body is also fixedly provided with a DC socket, and the DC socket is used to connect an external power source to charge the battery through the charging circuit of the control circuit board.

Because of its many advantages such as energy saving, environmental protection, light control, solidification, and long life, LED lights have been widely used in urban public lighting, office, indoor and outdoor lighting and other fields. The traditional Laser pointer has a single function and a single use scene. The traditional laser lighting equipment in the prior art is either large in size and difficult to carry, or has a short use time. The pen body is also provided with a battery, 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 through a constant current drive circuit Work; the control circuit board controls the work of the laser module through a laser drive circuit;
Further, the pen body is also provided with a COB light source key switch and a laser key switch, the COB light source key switch is used to control the on or off of the integrated COB light source through the control circuit board, the laser key switch It is used to control the opening or closing of the laser module through the control circuit board.
