Gaogong LED, with its excellent suppliers of components and accessories at home and abroad, helps Hangzhou LED lighting companies to further optimize the procurement channels of raw materials for lighting enterprises through on-site display and communication, and through screening and introduction of high-quality, cost-effective upstream yuan. Equipment and lighting accessories resources, in order to improve the quality of LED lighting products, while reducing product costs, to create favorable conditions for the export of Hangzhou LED lamps overseas.
Zhang Zhennan, R&D Manager of Jingtai Optoelectronics, introduced the newly launched PCT material lamp beads at Hangzhou Station. He said that at present, the entire LED packaging industry is still in the stage of driving new materials and new processes.
"The main function of the package is to protect and improve the reliability of the chip, so the choice of packaging materials is particularly important." Zhang Zhennan said, "The most important thing in packaging materials is glue, phosphors and brackets, especially the brackets that solve the heat dissipation of the chip. material."
He said that compared with EMC, PCT 1W products are not lost to EMC 1W products in various performance indicators, and the cost performance is relatively higher. At present, PCT materials are superior to existing conventional PPA materials in high temperature endurance, high temperature long-term yellowing, reflectivity, and UV irradiation, and can be tested by LM-80.
He revealed that some manufacturers have applied PCT materials to TV backlights, high-power lighting SMD LEDs, etc.
Next, the development trend of LED will continue to develop along the direction of high current and high power. The existing materials will still face bottlenecks such as high temperature resistance, long time high temperature operation, yellowing, UV, etc., so the rapid introduction of new materials has become a packaging enterprise. The next step in application development is the direction.
Wood Burning Stove is a direct combustion of dead leaves eliminated in the natural environment, leaving almost no residue after burning, only a small amount of white ashes, the planet of our existence has played a maximum of care.The actual use of metal skin in the ordinary home firewood stove wall adds a layer of air duct (convenient, then cut steel pipe can be used instead) around the bottom of the flame for oxygen supplemental combustion, the key is to use the thick hearth furnace production, the thicker The better, so that the top of the flame heat will be able to spread to the bottom of the bottom of the gasification of the decomposition of combustible gas, which is the same principle with the gasifier, because it is dependent on iron heat transfer, solid from top to bottom Iron hearth temperature is gradually decreased, so the firewood will burn down from the top.
