LED lighting industry will welcome the era of "modularization"

Guangming Net Energy News (Zhang Yan) At present, LED lighting technology is facing a new revolution. Especially in recent years, the LED lighting industry has developed rapidly with the strong support of the state. The modular technology known for its low cost and convenient operation has gradually become the mainstream development trend of the LED lighting industry in the future.

With the gradual maturity of LED modularization, the cost-reduced LED lighting industry will undoubtedly have a great impact on the current lighting system. Modularization will promote the LED lighting industry to reduce costs in the scale, and finally promote LED lighting products to enter "thousands of households", which will greatly promote the global lighting industry to enter the LED era.

LED modularization will become the general trend

Xiao Hongqing, Ph.D. of the Institute of Electrical Engineering, National Taiwan University of Science and Technology, believes that the direction of LED lighting in the future should be: correctly understand its illuminance and luminance-oriented application characteristics, provide a reasonable light distribution curve, reduce glare, and improve the diversification of color rendering and color temperature And solve the heat dissipation of the LED drive circuit, realize modularization, standardization and standardization. Coincidentally, Liu Muqing, vice chairman of the Shanghai Lighting Society and professor of the Electric Light Source Research Institute of Fudan University, also emphasized that LEDs should achieve product compatibility and interchangeability in functional lighting applications, and realize modularization, standardization and standardization.

At present, some LED high-tech enterprises represented by Changyuntong Optoelectronics focus on R&D and sales of LED modules. It is reported that the LED module is to standardize the work of LED lighting R&D and manufacturing, and integrate the light source, heat dissipation components, and driving power into a unified module. Lighting companies only need to purchase modules, and then add some simple parts and styling designs to manufacture. Out of the LED lights.

LED modularization has broken the manufacturing mode of LED lamps in the past, so that the rules of the LED lighting game are no longer in the hands of a few players. Many small and medium-sized enterprises and even individuals can participate. Once they are aggregated, they will form a powerful force. The subversive power of LED lighting will really usher in explosive growth by then.

Engineers who do power supply do not understand optical design, and engineers who do optical design do not understand power supply. This is a problem faced by many LED lighting manufacturers. As the drafter and participating unit of the Level 2 standard of the Guangdong Provincial Standard Optical Component Project, Changyuntong Optoelectronics integrates power supply and optical design to provide simple and easy-to-use LED surface light source modules for lighting factories. It is reported that the LED surface light source module mounts multiple LED chips on an aluminum substrate, encapsulates them with silica gel and adds phosphors, and at the same time encapsulates the constant current driver IC on the aluminum substrate. Adopting this structure can effectively reduce thermal resistance and facilitate heat dissipation, thereby reducing the probability of LED light decay.

Modular design seizes market opportunities

Modularization can greatly reduce costs under the premise of ensuring product quality, and terminal products manufactured through modularization usually have obvious price advantages. After LED modularization, lighting manufacturers only need to consider the appearance design based on the module, which not only greatly reduces the research and development costs of lighting manufacturers, but also shortens the time to market for new products to seize opportunities.

According to relevant personnel from Changyuntong, in the packaging process, due to the high cost of individualized manufacturing, if industrialized production is carried out and standardized, the entire cost can be reduced by 1/3. At present, Changyuntong mainly provides modules to customers. Compared with providing complete lights, modularization has a unified standard to follow, so everything is carried out according to the standard. The operating efficiency of this mode of Changyuntong is much higher than that of directly providing LED lights, which saves a lot of links.

The modular development model of LED lighting will greatly promote the rapid development of the domestic LED industry and lighting industry, and the maturity of the industry will also come earlier. This new mode of industrial division of labor is the redistribution of the original market power, and the most discourse power is undoubtedly the companies and individuals scattered in the terminal with keen tentacles, which will ultimately determine the direction of the LED lighting business model. When the module becomes the standard adopted by most lighting companies, it will not be far from the era of popularization of LED lamps.

At present, my country's LED industry has initially formed a relatively complete industrial chain including the production of epitaxial wafers, the preparation and packaging of chips, and the application of LED products. It can be seen that the application of LED light-emitting products is attracting the attention of the world. As a new type of green light source product, LED must be the trend of future development, bringing broad market prospects and new opportunities to the green lighting production industry. Modularization will bring more cost advantages and convenient experience to users, and will surely become the mainstream trend of LED lighting systems in the future.
