济南发光字寿命长的原因

白炽灯的发光机理是电能将发光钨丝进行加热而发光的,通过相当长期的加热,钨丝就会老化乃至烧断,至此,白炽灯泡的寿数也就此告终了,而济南发光字发光机理是由其特别的构成构造决议的。
Incandescent lamp luminescence mechanism is electrical energy of a tungsten filament is heated and glowing, by long time heating, tungsten wire will be aging and burnt out, so far, incandescent light bulb life also ended the Jinan luminous characters luminescence mechanism is by its special structure and structural resolution of.
二极管主要由PN结芯片、电极和光学系统组成,当在电极上加上正向偏压之后,使电子和空穴分别注入P区和N区,当非均衡少数载流子和多数载流子复合时,就会以辐射光子的方式将多余的能量转化为光能。其发光过程包括三个局部:正向偏压下的载流子注入、复合辐射和光能传输。
The diode is mainly composed of PN junction chip, electrodes and optical system, when the electrode with forward bias, electrons and holes are injected into the P and the N region, when the non-equilibrium minority carrier and majority carrier composite, the will to photon radiation excess energy conversion to light energy. The luminescence process includes three parts: carrier injection, composite radiation and light energy transfer under forward bias.
由此可见济南发光字主要是靠载流子的不时挪动而发光的,不存在老化和烧断的现象,其特殊的发光机理决议了它的发光寿命长达5-10万个小时。
This shows that the Ji'nan LED is mainly rely on the carrier's moving from time to time, there is no aging and burn off phenomenon, its special luminescence mechanism of the resolution of its light emitting life of up to 5-10 million hours.
