There has been a lot of novice consult how to DIY a best led flashlight, many beginners want to try DIY flashlight, because you will learn a lot in the process of assembly, after the success of the assembly, your heart will have the joy of success and pride. And you can also enhance the internal structure and working principle of the power to know your opponent, it can bring a lot of convenience for the future use and play. When you encounter some minor problems, and you will be able to solve.
Small led flashlight has hidden learning. Now I said about the composition of the flashlight, a flashlight is made by the shell, cup light or lens, lens, LED or light bulb, the circuit (light bulb without circuit), switches and other components. Subdivided into: O-ring, LED insulation pads, wires, circuit touch spring-loaded contacts, thermal grease or silicone lubricating grease and so on. The performance of the more advanced HID flashlight have used ballast.
To illustrate the use a variety of accessories:
1, LED luminous body, it is the key to determining the performance of a flashlight, LED advantage is that luminous efficiency (power saving) and a long life (theory 5-10 hours), power consumption is more powerful bulb type flashlight. But color is the best.
2, The circuit: the circuit is also very important, it is the premise of the LED can work smoothly, of course, LED also can work without circuit, but that would be unstable, and prone to damage. I do not consider the premise of the battery circuit and the 12 volt LED lights is the determining factor of the innate brightness of a flashlight.
3, Optical glass and lenses: optical glass is the convergence of the role of light divided into the two kinds of smooth and orange face. Smooth cup long-range, the orange Mianfan light better. It is more likely to be the perfect spot than smooth cup. The lenses serve to protect the optical glass and LED to prevent the entry of dust and water vapor and other debris. At the same time the quality of the lens will affect the light transmittance. Of optical glass and lenses are the determinants of the brightness of the flashlight the day after tomorrow. In addition to the lens a flashlight, can focus the focusing surefire the TIRClass lens;
4, Switch: it will not need to explain, it is the platform of the man-machine dialogue. Took part in the key switch, rotary switch and electronic switch. The key switch is the most used DIY flashlight, it is divided into forward and reverse switch. The so-called forward switch is to tap the burst, in the end to hear the long bright lock snapped switch, also known as a tactical switch. Tap is not bright, in the end lock after the bright reverse switch, the present reverse switch is the most widely used; there is still magnetic dimming switch is more popular, it is more difficult for the DIY flashlight .
5, O-ring, as the name suggests is to play a waterproof function.
6, LED insulation spacer: is placed between the LED and the optical glass to prevent light cup down to the LED wire and short circuit. Of optical glass with high-power flashlight is aluminum, it will be conductive, plastic will not.
7, Thermal grease silicone: the LED heat to help the smooth conduction of the contact surface of the LED circuit warehouse. Silicone sticky can be used to fix the LED, grease-free sticky but good thermal conductivity.
8, The positive and negative spring or contact: conductive function, the most widely used internal resistance the smaller the better is the gold-plated spring. There is also an important role in shock absorption, to prevent the impact of the battery and circuit vibration, which can prevent the poor contact and downshift. Spring stretching characteristics.
9, Lubricating grease: the threads of the flashlights casing, played the role of lubrication, but also to help waterproof. Grease quality is better, whether it will corrode the O-ring.
10, Wires: the role of conductive, high temperature and low-resistance is better. The high temperature silver-plated wire is commonly used.
I will continue to collect more DIY Flashlights.
