LED flashlight referred to as semiconductor light-emitting diodes, LED Bags Lights the current white LED on the market mainly for the blue chip to produce yellow phosphor made of white light, the wavelength is mainly around 460nm, are blue, very little UV components. LED is called the fourth generation of lighting, green lighting, LED Bags Lights the new house over time I intend to switch to LED lighting, LED Bags Lights although the current luminous efficiency is lower than the fluorescent point, but the same as incandescent no flash.
As for some of the argument that the flashlight put the box for 3 years no bad, is normal, but usually we usually mention the life of the LED, in general, LED Bags Lights there are 50,000 hours, not to mention you are placed in the box. Sometimes we are on the road to see some of the LED traffic lights do die lights phenomenon, LED Bags Lights this time most of the external electronic components are broken, rather than the LED itself.
Another advantage is that LED is fast response, especially for the car after the combination of lights, can significantly reduce the incidence of car accidents, do not underestimate these milliseconds, and sometimes can help.
Also mentioned that "white LED used in the flashlight are more bluish, look for a long time not very comfortable," I want to say is that the Chinese people like blue, LED Bags Lights foreigners like yellow. In fact, the color temperature can be adjusted, the current technology, 2500K to 10000K can be achieved, 2500K on the reddish, 10000K on the blue, the market is a lot of flashlight tube is a small number of domestic processing, Money one, LED Bags Lights and made after the flashlight is very expensive to sell, the profit is still very high. LED Bags Lights Warm color fluorescent light that we usually see the yellow fluorescent light, look carefully at its box will see a 2700, which is its color temperature, and white will be written 6500, which is the white fluorescent color temperature, relatively speaking, LED Bags Lights White brightness is higher. Is the color coordinates of 0.33 0.33, a lot of LED made after the finished color coordinates 0.29,0.29 can not blue?
Said so many words, LED flashlight despite the use, than the incandescent flashlight power, and no damage to the eyes, of course, you do not eyes, strong eyes on the eyes or have a certain burn.
Added: see someone say: "LED light intensity is relatively high, the intensity of the human eye can withstand the ability to burn the eyes to make it blind. It can be used as a laser source." Always add: laser for the LD, LED is LED, it seems that he is wrong.
