With the rapidly development of LED light source, fixture manufactories begin to use LED as the new generation of light source. The range of application refers to outdoor, industrial and indoor lighting. Due to LED’s technical advantage, it has gradually replaced traditional light source, including metal halide, incandescent, etc. As the increasingly mature of LED chip technology, the color of LED changes frequently with higher luminance, especially saving power, long lifetime and environmental protection. All these features make LED lights become the focus of lighting market.
At present, there are more than 100 LED fixtures’ manufacturing plants, mainly private enterprises. Most of fixtures are export sales with consideration to sale in domestic market because of the low consumption ability. Even so, the development of LED fixture market is still optimistic. However, many factories’ technology is not mature and the direction of product design is not right, so there are many price wars in the fixture market. In order to save cost, some manufactories use inferior materials and do shoddy work, and finally the quality of different fixtures varies. As a result, there are many problems in the quality and stability of products, besides, fixtures and manufactories leave customers bad impression. In order to find the best fixtures in the market, it’s necessary to learn some technological process of LED production. Let’s focus on the process of led high bay .
Firstly, LED light chip.
LED is a complete set of industrial chain. The cutting and production of chip and epitaxial slice are in the upstream, which is the most technical content link of LED industry. Epitaxial slice is mainly supported by Japan, Korea and German and chip comes from Taiwan. In addition, it’s worthy to point out that the packaging technique of Taiwan is also a leading position in the world.
Secondly, the packaging technique of LED High Bay
In terms of packaging form, it includes the following series, dual inline-pin 3mm, mm, 8mm, 10mm, super flux, surface mount device 0805, 0603, 1206, current 1210（3528）, 5050, and so one. Therefore, LED light has gradually developed from dual inline-pin to 0805, 0603, 1206 and the most popular 5050 in the market. It needs to pay attention that the luminance of LED High Bay is directly related to chip.
