“The growth momentum of our Ronda Electronics is mainly from LED lighting products, and from the first quarter of the product performance, the AC Direct DriveDOB directly driven by the high voltage package (HVLED) will become the lighting component of this year. Highlights of the product." Long Bo electronic finance vice president Zhang Boyi said.
From the development trend of the light engine market in recent years, the adoption of high-voltage LED modules (HVLEDs) has gradually become the mainstream route of current light engine technology. .jpg)
In this regard, Professor Yan Chongguang, a part-time researcher at the Shanghai Institute of Microelectronics, Peking University, pointed out that "due to the rise of HVLED technology and high-voltage linear constant current driver chips, LED lamp beads can be combined into a multi-string application mode and can use electroless capacitors. , DC power supply without transformer and inductor."
It is understood that high-voltage LED modules (HVLEDs) are high-voltage (DC45-280V), low-current (10-60mA) light source board applications. Among them, the biggest advantage of HVLEDs is the uniform distribution technology of HVLED and small current drive, which can effectively reduce the heating problem of LED light source.
"At the same time, the application circuit of the high-voltage linear constant current driving power chip does not need electrolytic capacitors, transformers, inductors, so that the high-voltage linear constant current power supply can be designed on the light source board to form a 'photoelectric engine', and the constant current driving power source is integrated in the LED. On the light source board, the high-voltage linear constant current chip, the rectifier bridge stack and the high-voltage LED lamp bead can be attached to the same board through the automatic placement machine to realize automatic production of the machine, thereby greatly saving labor and improving productivity.†.
Foreign markets are frequently exerted, and domestic companies are naturally not far behind. As early as last April, the new Xinli Light Source, which started the light engine earlier in China, held the “2014 New Force Light Source AC LED Light Engine New Product Launch Conference†in Zhongshan Guzhen, and officially launched the light effect at 90lm/W or above with a power factor of 0.9. Above, the products meet the requirements of CE, RoHS and other circular light engines, square light engines, strip light engines, ring light engines and other standard products.
“Xinli Light Source applies phosphor materials science to AC LED modules, and eliminates DC drive power and light source and drive integrated compact design through circuit optimization. It belongs to the independent research and development of the world's first AC LED light engine.†Zhao Kun, vice president of research and development of Xinli Light Source, told reporter.
At the same time, Zhao Kun also mentioned that more than 95% of the LED lighting products currently on the market are DC drive technology, and AC LED technology, which can be reduced to reduce cost and enhance product reliability, has not seen large-scale application. The reason is the strobo problem that is difficult to solve.
However, the AC LED light engine launched by Xinli is the biggest selling point of AC LED products compared with other companies. The company has successfully solved the stroboscopic problem of AC LED by combining its own patented phosphor technology. This is the technology of Xinli Light Source for ten years. The concentrated expression of the research.
Compared with the traditional switching power supply (AC/DC), the main focus of the green integration in the field of LED light engines is focused on the research of segmented linear constant current chips. According to the reporter, this program is a drive solution for electroless capacitors and inductors.
"As we all know, most of the current LED drivers use the traditional AC / DC power supply scheme, not only the circuit is complicated, but also the use of various components such as inductors and transformers, resulting in excessive volume, not easy to mass production and installation, and it is difficult to meet the design of LED lamp components. Request." Chen Heng, general manager of the green integration of the disc, mentioned.
Chen Hengyu introduced that the current green integration of Suipan has successfully developed the fourth generation of high-order piecewise linear constant current driver chip--SDS3108 series, which combines the "high-order segmentation", "dynamic configuration" and "automatic" of independent innovation. Based on the inherent advantages of the segmented linear constant current chip, the patents of “Filling Valley†have raised the power supply specifications to the level of the switching power supply and successfully overcome the stroboscopic problem, especially the high-order piecewise linear constant current drive. Close to the current sine wave, greatly improving work efficiency.
However, according to the research data of the High-tech Research Institute LED Research Institute (GLII), the market size of China's LED light engine in 2014 is still less than 100 million yuan. According to the GLII sample survey, among the mainstream LED lighting manufacturers in China, about 80% of the mainstream LED lighting companies have not used LED light engine products, and about 20% of enterprises are only using some products.
GLII believes that the current market acceptance of LED light engine is low and the market size is small. The main reason is that product stability is poor, and product performance needs to be further improved. Its specific performance is: 1, narrow voltage problem: most enterprises still have not effectively solved this problem, voltage fluctuations cause serious power drift; 2, product efficiency is low: most enterprises LED light engine product conversion efficiency is only 70-80%; 3. Some products have severe strobe.
"In the next two or three years, more companies will participate in the LED light engine market. At that time, the performance of light engine products is expected to accelerate. In addition, benefiting from the continued rapid development of the LED lighting market, the LED light engine market will have A good imagination space." Zhu Yuan, deputy director of the High-tech Research Institute LED Research Institute.
