As a kind of conductor solid light emitting device, LED has a longer working life than other light emitting devices, and its luminance half-life is usually up to 100,000 hours.
Long time working LED light decay causes aging, especially for high-power LED, light decay problem is more serious. When measuring the life of LED, it is far from enough to only take the damage of lamp as the end of the life of LED. It is more meaningful to define the life of LED by the percentage of light decay, such as 35%. The luminescent apparatus has a longer working life, and its luminance half-life is usually up to 100,000 hours.

Overview of PC lamp shade materials for LED lighting

led lighting is a new type of efficient solid light source using LED as light source [1,4]. It is called semiconductor lighting in China and solid-state lighting in the world. Its power consumption is only 1/10 of that of incandescent lamps and its service life is 100 times longer than that of incandescent lamps. It does not contain heavy metal mercury, so it has the characteristics of energy saving, long life, environmental protection, maintenance free and easy control. Therefore, led lighting is recognized as one of the most promising high-tech fields in the 21st century. PC lamp shade led unit area luminous intensity is too high, direct vision is very dazzling, glare, visual discomfort. For this, led lighting is needed


Application and characteristics of ABS pipe

High working pressure: at room temperature 2OC, the pressure is 1.ompa.


Why can PC lampshade crack

Many LED fluorescent lamp manufacturers in the production process, and fluorescent lamp aging in the process of use there will be cracks. Now I will analyze the cause of this crack. For your reference. PC material originally for polymer, its toughness is often good, in the normal range of material characteristics, the proportion of PC molecule cracking is less, that is to say, the cracking phenomenon of PC material is smaller. So why now the PC lampshade will appear to have cracking? The main reason is that the structure of PC molecular chain is damaged and the molecular chain is disconnected. Resulting in product cracking or surface cracks. Factors affecting the structure of molecular chains
