LED is short for lighting emitting diode; it was first invented by Russian scientist Oleg Vladimirovich Losev in 1920s. The advantages of LED are solid lighting, shock resistant, improved robustness, high brightness, low energy consumption, small size and fast switch, long lifetime, widely use range, and non-toxic to environment. Also LED has the disadvantage: relatively expensive, required precise current and heat management.
The world famous LED corporation are Cree(USA), The key to Cree’s market advantage is unrivaled materials expertise in silicon carbide(Sic) with gallium nitride(GaN) to deliver chips and packaged devices that can handle more power in a smaller space while producing less heat than other available technologies, materials and products. Cree’s product families include blue and green LED chips, lighting LEDs, LEDs for backlighting, power-switching devices and radio-frequency/wireless devices. Nichia(Japan), a Japanese chemical manufacturing company that is most widely known for producing phosphors, including light-emitting diodes, it is famous because it invented the first high brightness blue-light LED, which was based on gallium nitride in the world. The famous European LED manufacturer is Osram. In Asia, except Japanese LED corporations, Seoul Semiconductor and Epistar are familiar to people.
I am working in a LED factory in Shenzhen where is the most developed area in China, I am familiar with LED diode, LED rope light and LED light tube. Our factory’s customers usually are international trade importers and distributors, we supply them LED products with low price and proper quality. Our factory’s quality management system is ISO 90001:2000 and the environment management system is ISO 14001. Our factory’s diode, bulb and rope light have competitive price, because the CCP and government force the wage very low on purpose, that’s why the entire world blame Chinese product’s dumping, but if you want to spend less money, sometimes Chinese goods is a good choice.
The LED mainly has two type of package: cylindrical LED and SMD LED, to cylindrical LED, SMD LED is smaller, brighter and more high-power, both of them are widely used in decoration, illumination, indication, communication. The LED tube usually using with cylindrical LED, but more and more LED tubes choose SMD LED as the lighting source not the cylindrical LED. The rope light is almost using with SMD LED. If you are rich and pay attention to greenism, nowadays, LED maybe the best choice for decoration and illumination. If you are interested in LED likes me, welcome to share LED information with me, thanks.
