China's LED market is still a hot spot in the global industrial chain, especially in the past year, for the development of the domestic LED lighting market, once again set off a climax of LED industry construction. In order to further understand the development of China's LED lighting technology at this stage, we specially interviewed Li Jiahao, Director of China Business Division of Everlight Industries Co., Ltd., and asked him to talk about the current development of China's LED lighting industry and Yiguang Electronics. The latest trends in lighting packaging technology and product development. As a leading LED packaging company in Taiwan, Everlight Electronics continues to maintain its technological innovation. In recent years, many products have achieved outstanding results in the industry evaluation. From their sharing, they can also clearly show the industry. The latest developments are pulsating.
COB integrated packaging technology into the mainstream With the gradual maturity of the LED application market, users are increasingly demanding product stability and reliability, especially under the same conditions, requiring products to achieve better energy efficiency indicators and lower power. Consumption, and more competitive product prices. Based on this, compared with the traditional LEDSMD chip package and high power package, COB (ChipOnBoard) integrated package technology directly encapsulates multiple LED chips on the metal-based printed circuit board MCPCB, as a lighting module directly radiates heat through the substrate. Not only can reduce the manufacturing process and cost of the bracket, but also has the advantage of reducing the thermal resistance of the heat dissipation, so it has become a kind of LED lighting module packaging technology that many large manufacturers are currently pushing.
LED lighting industry integrated packaging technology into the mainstream For example, at the American Lighting Show in May this year, Everlight Electronics exhibited a new generation of high CRI and high efficiency C52COBLED series products, which use 3.7W ceramic polycrystalline package with high heat dissipation effect. The performance (Rth1.8C/W) and the performance of more than 100lm per watt and color rendering (CRI) over 80 at a color temperature of 3000K can be directly locked on the heat dissipation module, thus saving the SMT steps and providing more The cooling space is easier to assemble on the luminaire, creating a lower cost structure (a dollar is more than 400 lumens (400 lm / $)).
Li Jiahao, Director of China Business Division of Everlight Electronics (Hong Kong) Co., Ltd. said: The competition in the LED industry is becoming increasingly fierce. This requires manufacturers to continuously improve their core competitiveness to expand market influence. Ever since, Everlight Electronics has continued to maintain its technological innovation. The investment is expected to establish a symbolic product line in the LED lighting components industry. For example, we use our self-developed COB integrated light source packaging technology to help customers achieve maximum light efficiency in a certain unit area, saving customers a lot of manufacturing costs. In addition, with years of experience in the backlight market, Everlight also plans to introduce the know-how technology (such as heat dissipation technology, chip selection, etc.) in the backlight design into the development of LED lighting products, and will soon launch more Small package size, medium and high power LED products (such as: 0.5W), meet the requirements of spotlights and bulb manufacturers to achieve greater illumination brightness in a smaller package area.
LED lighting applications tend to be subdivided and diversified. The application of LED lighting in the domestic market is mainly concentrated in hot areas such as road lighting and architectural landscape lighting. At the same time, another phenomenon worthy of attention is that the lighting application field is getting finer and thinner. Points require manufacturers to provide alternative lighting solutions for different application environments.
For example, at the just-concluded Guangzhou exhibition, Yiguang Electronics brought visitors a real application experience by simulating multiple actual scenes. In addition to typical commercial and home lighting applications, Yiguang Electronics also demonstrated industrial and warehousing. , LED growth applications such as plant growth, they launched a series of low color temperature light source technology, high efficiency LED warm light street lights and industrial lamps, including the shell of the Yafu street light series, tunnel lights, floodlights and warm Light patio lamps, etc., provide LED lamps with the same low energy consumption and high brightness for lighting areas that require warm light color.
It is particularly worth mentioning that in plant cultivation applications, LED plant lighting products developed by Everlight Electronics can not only adjust the ratio of the wavelength of the light source required by plants, but also accelerate the growth rate without affecting the original quality of the plants. It can reduce the power consumption and growth period during planting, making it an ideal light source choice for plant factories. For example, plant lighting products launched by Everlight Electronics can promote the development of plant roots by increasing blue light; or accelerate the growth of leaves by increasing red light; by increasing the ratio of 9:0:1 of photosynthetic area to 8:0 to promote plant growth rate: 2 ratio; or enhance the taste, increase the brittleness of 8:1:1 ratio, etc., can meet the requirements of the plant growth stage light source. In addition, Everlight Electronics has launched a large plant lighting GL-Chauntea to meet a wide range of plant lighting.
Li Jiahao said: Yiguang Electronics is a leading manufacturer of LED packaging industry in Taiwan, and has a full range of product lines including HighPowerLEDs, Lamps, SMDLEDs, Display, Infrared and lightingmodule, etc. Currently, the company's business is still dominated by LED components, and in China. The mainland has established two production bases (Zhongshan Xiaolan and Suzhou Wujiang), and the business revenue generated in China has accounted for more than half of the total turnover. In the future, China will remain one of the key markets for Yiguang Electronics' key development. We will actively promote the impact of our own brand Everlight LED lighting products on the mainland market based on the existing product sales channels. force.
Looking forward to the next stage of LED lighting packaging industry development, smaller package specifications, lower manufacturing costs, and higher energy efficiency indicators are the general direction of the overall technology, around this topic, COB integrated packaging technology and more The diversified LED lighting product solutions will further promote the in-depth development of the application market.
