LED light engine rapid growth in the next two years, stroboscopic high pressure problem remains to be solved

According to the statistics of the High-tech Research Institute LED Research Institute (GGII), the scale of China's LED light engine market grew rapidly to 218 million yuan in 2015. GGII expects that the growth rate of the light engine market will remain above 100% in the next two years. By 2017, the scale of China's light engine market will reach 2.832 billion yuan.

The light engine was first launched by international lighting companies such as Philips and Osram, and was established in 2010 by the Zhaga International Alliance, an LED industry cooperation organization. It aims to promote the standardization of lighting products and realize the interchangeability of LED light source products from different manufacturers. .

As we all know, before 2015, there are not many applications of light engines, and more are still in the small-scale application stage. For many LED lighting companies, the light engine is a "new thing", no matter the product performance or technical understanding is not particularly accurate. Many companies look at the light engine with a more cautious attitude.

"The light engine itself has many advantages. Everyone needs to be familiar with it. It needs a process of adjusting the understanding. Although the market has not formed so quickly, the trend has gradually formed." Zhao Kun, vice president of Xinli Light Source, said.

After entering 2015, more manufacturers began to enter the field of light engines and formed certain sales. Although the absolute value of sales is not large, it has been greatly improved compared with the previous period, and it has also paved the way for the official opening of the market.

It is understood that the current light engines produced by domestic LED companies are mainly used in the field of indoor lighting such as LED downlights, spotlights, and ceiling lamps. In addition, there are a small number of applications in the field of outdoor lighting. With the growth of the indoor LED lighting market, the application of LED light engine products will also become popular.

“The light engine has always been the focus of the new light source. Currently, it is used in many fields such as street lamps, mining lamps, floodlights, downlights, panel lights, etc., especially on street lamps and mining lamps, 2015 The application of the year accounted for more than 60% of the total, and has formed an upward trend. It is expected that there will be several times of growth in 2016.” Zhao Kun told Gaogong LED.

More than Xinli Light Source, the sales of light engines in the packaging companies such as Smect and Zhonghao Optoelectronics in 2015 are also considerable.

“Relying on several existing stable lighting customers, the sales of LED light engines reached 800W in 2015. At the end of the first quarter of 2016, sales were at 200W, up 20% from last year.” Marketing Director of Smale Zhang Luhua said.

In fact, Smect has a clear positioning on the LED light engine in 2016. In the early stage, it will continue to improve the application of the optoelectronic integrated LED light engine in the high-end lighting market, and will also utilize existing packaging equipment and technology. Resources and other advantages to develop LED light engine in the form of AC-COB.

Wang Mengyuan, general manager of Zhonghao Optoelectronics Co., Ltd. also said, “Since last year, Zhonghao Optoelectronics has been continuously optimizing product performance and laying a solid foundation for improving the competitiveness of the product market. At the end of the first quarter, sales of light engines have turned 2% last year. - 3 times. It is expected that the light engine will occupy 20% - 30% of the company's overall products in 2016, and may even be even higher."

There are also many people in the industry who believe that the penetration rate of light engines is not high in the domestic lighting market, and the market is not mature.

Zhang Luhua believes that the domestic LED light engine market is still immature. The ordinary light engine can not fully meet the safety specifications and meet the electrical performance requirements. Therefore, most enterprises use multi-section voltage distribution to control the cost, which leads to the performance of the light engine. And the price advantage is not obvious.

However, not every enterprise can solve the problems of stroboscopic, overheating and unstable voltage instability of the light engine. This is a technical threshold and a stumbling block that hinders the light engine to increase market penetration.

Zhao Kun said that accepting a new thing requires a process. It is not just technologically advanced that it can immediately form orders and market penetration. It also needs to undergo a series of processes such as commercial promotion, market research, product development, information feedback, and product adjustment.

In fact, Xinli Light Source is also doing this process. For the stroboscopic problem of the light engine, the afterglow controllable rare earth phosphor and the AC LED chip are used together to solve the problem; for the photothermal problem, the material use, the heat dissipation management, the heat sink design and matching, and the use of the heat dissipation channel are all influencing factors; For the problem of high voltage instability, Xinli's driver chip can also be well solved to ensure the stability of output power and luminous flux under a relatively wide voltage.
