What is an led flashlight?
One of the most important factors that distinguishes led flashlights from other types of flashlights comes from its light source, that is, light emitting diodes. It is because of the light-emitting diode that it becomes a high-brightness flashlight. Led flashlights are not only more energy-saving than other flashlights, but also waterproof and anticorrosive. Even after several years of use, the brightness is very strong. This flashlight is often used in fire fighting and public security systems, and can also be used for emergency lighting in chemical industry and coal mines.
Luminous Principle of Strong Light led Flashlight
Compared with other flashlights, the light-emitting principle of light-emitting diodes is more complicated. The injected electrons and valence band holes directly combine to emit light. In another case, the injected electrons are first supplemented by the luminescence center and then combined with holes to emit light. In addition to this composite luminescence, the luminescence principle of led flashlight can not be separated from other released energy. The greater the proportion of non-luminous compounds in flashlight, the higher the efficiency of light quantum.
Advantages of strong light led flashlight
High energy saving: This is a pollution-free led flashlight with relatively low power consumption.
Long life: This kind of led light source is also called "long life lamp". In the solid-state cold light source, the lamp body is not easy to loosen.
Variety: Don't think that led flashlights must have white light, and there are different lights of red, green and blue light, and they can even be mixed with each other to form different light and color combinations.
Hi-tech tip: this is a low-voltage microelectronic product, which combines many high-tech technologies such as image processing technology and network communication technology.
Having said that, you should know that all the above introductions are useless if you don't grasp the key points of led flashlight purchase. Therefore, Bian Xiao finally suggested that you must identify qualified enterprises when purchasing, so as to have an led flashlight with long service life.
