High power COB LED, or High Power Chip on Board LED, has become a significant trend in the lighting industry. This innovative technology combines the advantages of traditional LED and COB technology, offering higher brightness, lower power consumption, and longer lifespan. In this article, we will explore the concept, development, and application of high power COB LED in the industry.

Introduction to High Power COB LED

High power COB LED is a type of LED that integrates a large number of high-power chips onto a single substrate. This technology is characterized by its compact size, high luminous efficiency, and excellent heat dissipation. Compared with traditional LED, high power COB LED has a higher luminous intensity and can achieve a higher brightness with the same power consumption. It is widely used in various fields, such as automotive lighting, outdoor lighting, and commercial lighting.

Development of High Power COB LED

The development of high power COB LED technology can be traced back to the late 1990s. At that time, with the continuous improvement of LED chip technology, the luminous efficiency of LED products began to exceed that of traditional lighting sources. In order to further improve the brightness and luminous efficiency of LED products, researchers began to explore the integration of multiple chips on a single substrate, which led to the birth of COB technology. In the early stage of COB technology development, the main challenge was the heat dissipation problem. Due to the high density of chips and the compact structure, the heat generated by the chips could not be effectively dissipated, which would affect the performance and lifespan of the product. With the continuous improvement of heat dissipation materials and technologies, the heat dissipation problem of high power COB LED has been gradually solved. In recent years, with the continuous optimization of the chip structure and packaging process, the luminous efficiency and lifespan of high power COB LED have been significantly improved. At the same time, the cost of high power COB LED has also been reduced, making it more competitive in the market.
