Background technology

Light-emittingdiode (English: Light-EmittingDiode, to be called for short LED) is a kind of semiconductor element.Multiplex as indicator lamp, display board etc. at the beginning; Along with the appearance of white light emitting diode, be also used as illumination.

It is the new type light source of 21 century, has the advantage that the conventional light source such as efficiency is high, life-span length, not cracky cannot compare with it.When adding forward voltage, light-emitting diodes physical efficiency sends monochrome, discontinuous light, and this is the one of electroluminescent effect.Change the chemical composition of the semi-conducting material adopted, light-emittingdiode can be made to be emitted near ultraviolet ray, visible ray or ultrared light.

Due to LED operating voltage low (only 1.5-3V), can active illuminating and have certain brightness, brightness can use again voltage (or electric current) to regulate, shock-resistant, anti-vibration again itself, life-span are long, therefore increasing application is served in display field, especially utilize in fluorescent lamp field, there is the technological merit that brightness is high, the life-span is long.

But, current fluorescent lamp body is all generally adopt PC tubular construction, when normal work, temperature on light source board is generally at about 60 DEG C, especially bulb lamp, because its heat gathered is not easy heat radiation, easily cause the caloric value of LED equipment high especially, thus it break down than being easier to.
