LED flashlight is led as a light source of a new type of flashlight, then, you know the advantages and disadvantages of LED flashlight what? LED flashlight has the advantage of cold light, low fever, will not damage the lamp holder high security, reaction speed, collision-resistant, small size, easy to quantify and so on. How to buy LED flashlight? First of all, the head of the LED flashlight should be moderate, household generally not more than 12 head. Second, the LED flashlight welding to the prison.
LED flashlight is led (light-emitting diode) as a light source of a new type of flashlight. Because led has high brightness, low power consumption, long life, small size and so on, LED Flashlight it is the ideal choice for the portable lighting.
The advantages of LED flashlight:
1, led super long service life, generally can reach more than 50,000 hours than traditional tungsten life $number times higher than.
2, cold light, low fever, will not damage the safety of the Lampholders high.
3, fast response, collision resistance, small size, LED Flashlight easy to small lightweight and so on.
4, save electricity, energy saving, new environmental protection bulb.
5, fast reaction speed as long as 1us (microseconds), LED Flashlight no need to warm the lamp to improve safety.
6. Low voltage drive safety.
8 points to buy LED flashlight
1, head number, the head number should be moderate. Household generally do not exceed 12, the use of batteries in the $number section for good, and then a little wave, LED Flashlight for other special needs can be determined by their own needs. Of course, high-power LED flashlight generally can not reach 12 of the number.
2, welding, welding to prison. Each of the two polar body is connected by welding on the circuit board, if there is no contact with the virtual welding is not good, it may cause beads not bright or affect the overall use.
3, batteries, there are ordinary batteries and lithium, LED Flashlight although lithium battery rechargeable batteries, but low life, about 2 years, led life of about 10 years, can be selected according to the actual situation
4, brightness, good LED flashlight high brightness, attenuation speed is slow.
5, the light bulb, the light bulb out of the case, the naked eye is difficult to distinguish between its good and bad, can be lit in the case of light bulb consistency.
6, waterproof, good LED flashlight with waterproof function, good seismic performance, that is, resistance to fall. Because it belongs to electronic products, flashlight front part of a circuit board, LED Flashlight once the water is easy to short-circuit, causing damage.
7, the aperture, good LED flashlight aperture is a circle evenly, the difference LED flashlight spot divides into the yellow blue two color uneven distribution. Beads concentrate as much as possible. This kind of flashlight is not like ordinary flashlight can adjust focal length, LED Flashlight buy should pay attention to do not have astigmatism phenomenon.
8, appearance, can choose aluminum alloy shell, beautiful and generous.
