半导体材料有一个非常有趣的特性,就是所谓的载子;载子分为两类:一类为电子,带负电;另一类为电洞,带正电。济南发光字的发光原理是利用两种载子在某些条件下可以结合,释放出的能量以光子的形式释出而发光。它会依材料的不同,电子和电洞所占有的能阶不同,也就是说电子和电洞的相对能接高度差即是决定两载子所结合发出能量的高低,便可以产生具有不同能量的光子,藉此可以控制LED所发出光的波长,也就是光谱或颜色。
Semiconductor materials have a very interesting characteristics, is the so-called carrier; carrier is divided into two categories: a class for electronic, negatively charged; the other for electric hole, positively charged. Jinan luminous characters of the light-emitting principle is using two carrier under certain conditions can be combined, release energy in the form of photon release and glow. It will depend on the material, electrons and holes to different order, that is to say, the electrons and holes relative to height difference is decided to carry two sub combination emit energy level, they can generate photons with different energies, thereby can control the LED emits light of wavelength, is or color spectrum.
济南发光字所使用的材料是以3A-5A元素化合物半导体为主(如GaP , GaAs , GaN , AlInGaP 等等)。而至于它为什么会发出不同颜色的光,就得是LED他本身的材料而定,例如:红光就用AlInGa(鉮化铝镓)、绿光就用GaP(磷化镓)、蓝光就用ZnS(硫化锌)或GaInN(氮化镓铟)?等等。
The material used in Ji'nan light emitting word is based on the 3A-5A element compound (e.g. GaP, GaAs, GaN, AlInGaP, etc.). And as to why it will emit light of different colors, material is led his own set, such as red light is used AlInGa (arsonium AlGaAs), green with gap, blue with ZnS (zinc sulfide) or GaInN (indium gallium nitride)? And so on.
济南发光字 http://www.kangmingda.com/ 依其发光波长来区分,可大致分为可见光二极管与红外线发光二极管。其发光原理是利用半导体中电子与电洞结合时,将释放的能量以光子的形式释出而发光,而发光二极管所使用的材料以3A、5A族元素的化合物半导体为主,如:GaAs,GaP,AlGaP,AlInGaP等等,其发光波长和亮度会因所使用的材料而有所差异。
Ji'nan light emitting word according to its luminous wavelength to distinguish, can be broadly divided into visible light emitting diode and infrared light emitting diode. The light-emitting principle is combined with the use of semiconductor electrons and holes, will release the energy to photon release of luminescence, and the light-emitting diode materials to 3a, 5A group elements in a compound semiconductor, such as GaAs, gap, AlGaP, the AlInGaP and so on, the emission wavelength and intensity will vary depending on the materials used.
二、济南发光字优点
Two, Ji'nan luminous character advantages
1. 属于冷性发光:不是藉由加热或放电发光。
1 belong to the cold light: not by heating or discharging luminescence.
2. 寿命长:可达十万小时以上(几乎可有十年不坏的寿命)。
2 long life: up to one hundred thousand hours (almost ten years not bad life).
3. 消耗电力小:约是传统钨丝灯泡得十分之一,因为氧化电位低驱动电压相对就低。
3: small power consumption is about 1/10 traditional incandescent light bulbs, because the oxidation potential of low driving voltage is relatively low.
4. 污染低。
4 low pollution.
5. 体积小。
5 small volume.
6. 反应速度很快。
6 reaction speed is quick.
