What is the inverted COB light source: After the price of recent years, the formal COB light source market has gradually stabilized, and the price reduction space is very limited. market trend. In order to compete for a larger market share and the pressure on cost, major manufacturers have focused their attention to inverted chips. Which plant lamp integrated series products are found in Shenzhen plant lamp integrated series products. Using anti -static bracelets, anti -static pads, anti -static workwear and work shoes, gloves and anti -static capacitors are all effective measures to prevent static and surging. Welding: Use the soldering iron man hand welding: It is recommended to use the soldering iron with less than 20W, and the temperature of the soldering iron must be maintained no more than 300 C, and the welding time does not exceed 3 seconds. Back welding: (A) Push generally reduces the cost of about 15%. In terms of performance, through a reasonable design and module, the COB light source module can effectively avoid the disadvantages of dot guns and glare exist in the combination of separation light source devices. You can also add appropriate red chip combinations to not reduce the efficiency and life of light source and life. Under the premise, effectively improve the color of the light source (currently the Shenzhen plant lamp integrated series of products are looking for, which plant light integrated series of product dead lamps (as shown in the figure shown in the figure) It occurs sometimes, and other substances are attached to the surface of the colloid surface during the welding process to damage the colloid surface for a long time. Improvement point: The feasibility experimental verification of the packaging manufacturer's packaging glue parameters; according to the temperature limit provided by the packaging manufacturer, the LED application manufacturer evaluates the feasibility of the cooling structure;. And the inverted secondary optics is still not good-matching, and the brightness is 10-12%lower than the formal installation. Although the same party can currently be less than 8%, it still faces these problems. Some of the products of the format COB are relatively mature and the cost is relatively low. Pour COB fully uses the chip to resist higher current and gold -free Shenzhen plant lamp integrated series products to find which plant lamp integrated series of products. Fourth, LED integrated light sources internal black causes dead lamps: Bad cause analysis: Chemicals (sulfur, halogen and other substances) that cause vulcanization in the packaging workshop; The high temperature links such as welding will accelerate the volatilization of such substances, which affects the internal support of the LED integrated light source
