Dva faktory vedenie do svetlo rozpad
At prítomný, the white light led in the market may be one of the first problems to the civil illumination. What causes the LEDs to fade? Generally speaking, there are two major factors in light attenuation for LEDs:
First, the quality of LED products:
1, the use of LED chip poor physique, brightness attenuation faster.
2, the production process has defects, LED chips cooling can not be good from the pin to export, resulting in high temperature led chip to boost the chip útlm.
II. Podmienky z Použitie:
1, led for konštantný prúd pohon, niektoré led by použitie of napäťovo riadené príčiny of LED útlm.
2. Šoférovanie aktuálny je väčší ako the rated jazda stav.
In fakt, LED výrobky príčina a veľa z svetlo zlyha, the most important vec je teplo, hoci veľa výrobcov in sekundárnych výrobkov do not pay special attention to the problem of heat, ale tieto sekundárne led produkty v the long-term use, the degree of light decay will be higher than the heat-focused LED products. The LED čip sám odpor, the vplyv z the striebro lepidlo, the teplo rozptyl efekt z the substrát, as well as the koloid a the Gold Line are tiež súvisiaci k na the light rozpad.
