Compared with the traditional lamp, the COB LEB lamp advantage is continuous improvement COB package technology is getting more and more recognition. Because of the COB LED lamp has some feature such as: low heat resistance. high flux density，less glare, light uniformity, so the LED COB has widely application in the LED market. such as: Lamp, bulb, fluorescent tubes, street lamps and mining lamp。In here we will description of COB LED lamp relatively advantage than the traditional LED package. Follow we will be put forward the five advantage: LOW heat resistance,Light quality, application advantage, cost advantage. The produce efficiency and produce flow is same basically，but COB LED is high efficiency than traditional smd led on Dispensing, separation, splitting, packaging. The SMD report states that 10 percent of the materiel cost to the laborage and produce cost. If use the COB LED to replace traditional SMD lamp, the worker ‘wage and produce cost will be save to 5 percent. The COB LED is low resistance package(surface light source),widely visual angle and adjust easily, reduce loss of light refraction, application advantage：forenamed the COB LED was quite wide of the market application. such as LED Light Tube ,high strip.At the sight of the data and note above, we can be knows that the save-cost range from 19% to 32% when with the COB LED to replace traditional SMD lamp, so The produce cost reduced their led market demands. The business rivals To become diminished.
