How many glory is added to the light engine when it is in place

[Text / high-tech LED Xiong Yuheng] For the LED industry, the light engine is no longer a new thing. Since 2010, in order to simplify the process and reduce production costs, the concept of a light engine has been proposed in the LED industry. By integrating the LED light source lamp bead and the driving chip on the aluminum substrate or the ceramic substrate, the optical engine prototype in which the LED light source panel and the LED power source are combined is realized.

With the concept of “de-powering” being hot, the voice of the light engine is getting higher and higher. In general, the advantages of the light engine are many, such as the linear cost can be lower than the non-isolated power supply, and flat with the RC. At the same time, the linear solution is simple to produce, low cost, easy to automate production; high reliability, easy to over EMI The advantages of intelligent dimming are obvious and so on.

"The high-voltage LED lamp bead and the high-voltage linear drive IC are effectively integrated, and the surface is attached to the aluminum substrate. The AC110/220V power supply can work, which greatly reduces the processing cost and labor cost, and shortens the production cycle." Manager He Gang believes that the light engine is only one radiator shell away from the finished lamp, and it takes only half a minute to complete the assembly of a single LED lamp.

At the same time, in order to make finished lamps, traditional LED lamp manufacturers often purchase components such as lamp beads, driving power supplies and aluminum substrates, which are not only expensive to manufacture, but also have low compatibility and stability. The light engine integrates the lamp bead, the aluminum substrate and the driving power source into a module, and once the batch supply is realized, the above problem can be effectively solved.

Today, there are not many companies that do light engines in China, including Xinli Light Source, Jingke Electronics, Hongli Optoelectronics, Zhonghao Optoelectronics, Smect, Meiya Optoelectronics, Optoelectronics, and Liyang Optoelectronics. However, despite the numerous advantages, the development of the light engine is not smooth. Throughout the domestic lighting market, the penetration rate of the light engine is negligible.

"The light engine will cause serious power drift due to voltage fluctuations, so the stability of the voltage is high. At present, related companies have not solved this problem. If the cost of making full voltage will rise, now everyone uses multi-section voltage. Distribution to control costs, resulting in light engine performance and price advantage is not large." Gao Shengcai Research Institute LED Research Institute (GGII) senior analyst Li Shengfa mentioned.

Secondly, in terms of market acceptance, the light engine will have an advantage in high-power lamps. "The domestic LED lighting market is very large, and the light engine will not have a subversive impact on the industry. The light engine will have an advantage in the indoor lighting field of 7 watts or more. After all, the traditional power supply of 7 watts or more is costly and is expected to be light. The engine was replaced," said Yang Dong, general manager of Deming Micro.

Domestic companies are also trying to solve the problem of heat dissipation that always exists in light engines. For example, Xinyue Optoelectronics adopts the method of module splicing. The light source part and the power part are divided into two modules. Each module uses different material substrates: the superconducting aluminum and copper plates are used for the light-emitting part, and the insulating plate is used for the driving part. Thermal resistance to solve heat dissipation problems.

In the production process, New Thinking Optoelectronics uses cold forging to produce modules, and then combines glue and respirator to do high voltage, which can effectively solve the problem of moisture and heat dissipation.

However, similar to CSP, although the process is bumpy, the light engine will become a future trend. "The LED industry chain is developing towards integration. In the future, if we can enable the light engine to integrate more systematic information, including intelligence, sensing, dimming and other functions, to achieve a new leap in technology, the light engine has great potential. Digging." Zhang Qiang, president of Xinli Light Source, said.
