Quantum efficiency is not high, that is, in electrons and holes compound tense, 100% photon can not be all generated, commonly referred to as by " electric current is let out
The recombination rate of the leakage " area Er Shi PN carrier reduces.Leakage current multiplied by voltage is exactly the power of this part, that is, is converted into heat
Can, but this part does not account for main component, because internal photon efficiency is already close to 90% now.The photon that inside generates can not be complete
Portion injects to chip exterior and is finally translated into heat, this part is main, because this at present be known as external quantum efficiency
Only 30% or so, be largely converted to heat (although the light efficiency of incandescent lamp is very low, only 151m/W or so, it
All electric energy are almost converted to luminous energy and are radiate, because most radiation energy is infrared ray, light efficiency is very
It is low, but the problem of eliminate heat dissipation).If the heat generated that shines is removed not in time, will be generated in the fluorescent tube short time
High temperature, fluorescent tube will be burned out, so important considerations when heat dissipation is such tube design.Meanwhile such as in general smooth chlorine
Change reaction in, optical chlorinating reaction temperature between 60 DEG C -110 DEG C, this be to the use of LED light it is unfavorable, LED light can be shortened
