Now take out the laser pointer module that you purchased earlier, leave its head and back part, remove the lens and spring of the laser module head, replace the original diode with the laser diode just removed, pay attention to the plus and minus of the laser diode The poles should correspond to the positive and negative poles of the socket. After fixing the diode, install the lens and spring back to the laser module head as it is.
Unscrew the lamp cover of the flashlight, remove the bulb from the flashlight, and replace the laser module head just removed. If the flashlight's lens is plastic, it must also be removed to avoid melting by high-power lasers.
Note! The green laser pointer emitted by the laser diode of the DVD burning drive is powerful, it can light cigarettes, light candles, burn through film, so we should be careful in daily use, otherwise it will easily cause some accidents. Laser flashlights should not be exposed to flammable and explosive items, such as alcohol and firecrackers. Of course, they should not be exposed to the human body, especially the eyes, otherwise it will burn through the retina and cause permanent blindness.
