Generally speaking, commercial places have high requirements for the display, illumination, color temperature and light efficiency of lighting products, because high-quality lighting effects can improve the quality of products and stimulate consumers' desire to purchase. LED lighting, especially the rise of COB light sources, has rapidly set off lighting applications in the commercial field, becoming the dominant light source for each window. Compared with the ordinary LED light source, the first one is that the COB light source can evenly solve the spot problem, and the secondary optical matching is effectively carried out, which is more suitable for the key lighting application requirements of commercial places; the second is that the heat dissipation performance of the COB light source has obvious advantages and can meet the long commercial position. The lighting requirements of time; third, the COB light source can change the light-emitting area and external dimensions to meet the diversified and personalized appearance requirements of lighting products in commercial places. Therefore, in the past two years, COB has become a must for all LED packaging companies. International manufacturers are also trying to use the high-quality and high-efficiency COB products to open up the gap with domestic enterprises and seize a large share of the market. The domestic flip-chip technology leader Jingke Electronics has applied the mature flip-chip non-gold wire packaging technology to develop COB light source products with high reliability, low thermal resistance, high current use, uniform light color and other technical advantages for business. The field brings unprecedented light quality enjoyment and is highly competitive in the market. It is understood that Jingke has launched COB products in the past two years, but it is only used in conventional lighting products such as commercial lighting and hotel lighting. This year, it will launch a series of products with small luminous surface and large luminous flux output. 5050 and 7070, specifically in the low power or 12W COB products will go in two directions. The 5050 and 7070 products are mainly for customers in domestic channels; the products with small luminous surface and high luminous flux are exported to the market, and they are mostly concentrated in the North American market. Although the product has just launched the market soon, but the market response is more enthusiastic, Jingke Electronic Products Director District Wei Neng revealed that the current COB line has reached 5KK / month of production capacity, after all, the difference between low power and high power capacity. In addition, it is also good in customer feedback, the feedback points are mainly concentrated in two aspects: First, compared with the traditional light source, can achieve a smaller volume; Second, it is used to replace the metal halide lamp, halogen lamp and other light sources, in the life There will be obvious advantages in terms of aspects. In fact, in the early stage of research and development, Jingke Electronics also encountered some thorny problems. Because COB is used in the field of spotlights, it needs to solve the optical angle, reflective cup and other supporting problems. In order to achieve better lighting effect, we are in this aspect. Development takes more time. District Wei can say frankly. He further added that since customers are accustomed to the light color of traditional metal halide lamps in application, the lighting effect of LED color light is different from that of metal halide lamps, and Jingke will focus on light quality, light color, etc. in the future. In terms of improvement, we will also make some customized products in line with customer optimization. Because the application product has special characteristics, and the user's preference for light beam and light color is different, there are different requirements in the product. At the same time, Jingke also pays close attention to the close contact with customers, and further improves the products through customer feedback to meet the needs of the market and users. After LEDs enter the field of lighting, general-purpose products such as bulbs, flat lamps, and lamps have reached a stage where technology is relatively mature, but COB is still increasing the proportion of applications. Its market growth will be in the next two years. There is a clear increase. Significantly different from small and medium power LEDs, LEDs will be standardized, while COB will be the opposite, will go to a customized, personalized market, the overall market usage will gradually increase. Weixin is optimistic about the future prospects of COB products.
