At the meeting, Dr. Zhang Xiaofei, CEO of Gaogong LED, Zhou Xuejun, Sales Director of Philips Asia, Wu Gan, Executive Deputy Director of Hongli Optoelectronics Engineering Technology Center, Li Zhaohua, Deputy General Manager of Mingwei Electronics, Guo Jun, Director of Sanxi Aurora Marketing, Zhang Chao, Director of Mulinsen Region Zhou Shuiming, general manager of Jiamei Times, and Jian Yucang, general manager of Confucian Electronics, gave a major speech respectively, and discussed the transformation and development of the traditional lighting supply chain together with the guests, and also brought high-quality, cost-effective components and accessories. The main quality of Zhongshan LED lighting products is rapidly upgraded.
　　 During the interview, a number of LED lighting industry chain companies said in an interview that the international market has improved since the beginning of the year, and the current order situation is relatively optimistic.
At the time of the outbreak or in the middle of the year
"In January, it was not a good time to see the spring sleep. In February, it was already Xiao He's sharp point." Zhang Xiaofei, president of the industry research institute Gaogong LED, described the recovery of the LED lighting market at the beginning of the year.
In fact, the recovery of LED midstream and downstream industries has long been recognized by the capital market. Since the beginning of this year, the A-share LED sector has been among the top gainers. The logic behind the rise in stock prices is that the performance of listed companies has stabilized and rebounded.
According to the statistics of the High-Tech LED Research Institute (GLII), 25 key listed companies in Shanghai and Shenzhen have a total operating income of 48.409 billion yuan in 2012, a year-on-year increase of 9%, and a total net profit of 3.933 billion yuan, down 18% year-on-year; In the first quarter of this year, the total revenue of these 25 companies was 9.888 billion yuan, a year-on-year increase of 12%, and the total net profit was 719 million yuan, down 3% year-on-year. The scale of the industry continued to grow and the downward trend in earnings slowed down.
Specifically, the net profit performance of midstream packaging and downstream application companies is better than that of upstream chip companies, mainly due to factors such as severe overcapacity of upstream chips and low operating rate of enterprises.
A research report by a securities company showed that both the chip and the packaging factory were in full load. The order visibility was 1~3 months, which was much better than the normal level, and some companies even took the initiative to give up the order.
“Before the industry expects the market to break out in 2015, I feel that it is conservative and it is necessary to advance to 2013.†Zhang Chao, director of the lighting division of Mulinsen Co., Ltd., is optimistic about the development of the LED lighting market.
In this regard, Zhang Xiaofei also agreed. He believes that from the beginning of February this year, the signs of the LED lighting market are already very obvious. It is expected that there will be a full-scale outbreak in the second and third quarters of this year.
Philips Lumileds, who is in the middle of the industry, has a steady stream of orders this year. Zhou Xuejun, director of the company's Asian market, said that the second plant in Penang, Malaysia, had started construction last year, but the orders on hand are still too busy.
Referring to the overseas market, Zhou Xuejun said: "The demand is strong, very hot."
Lighting market penetration will exceed 10%
For the reasons for the market recovery, Zhang Xiaofei believes that on the one hand, the global market has increased the acceptance of LED lighting, and the demand for export has shown rapid growth; on the other hand, the domestic commercial lighting market has begun to apply LED lighting products, while the public lighting market continues. promote.
"This year, the domestic LED lighting market penetration rate will exceed 10%. In 2015, this data will reach 35%. These data may be too conservative." Zhang Xiaofei said. Zhou Xuejun believes that the market penetration rate can not be generalized, depending on the market segment. At present, the market prospects in the field of public lighting and commercial lighting are relatively large. The penetration rate in 2013 may be more than 10%, and the civil lighting may be relatively weak. “However, this is enough to support the recovery of the entire market. Public lighting and commercial lighting account for about 70% of the total market.â€
Some local government bidding efforts are increasing. Recently, the website of the Guangdong Provincial Department of Science and Technology released the tender for street lamps in the first quarter of 2013. In the first quarter of this year, the number of street lamps and tunnel lights in Guangdong Province has reached 76,000, which has exceeded the total amount of 75,000 in 2012. Hey.

A hybrid inverter is an inverter that combines the functions of an inverter and a charge controller. Its main function is to simultaneously process the direct current generated by solar panels and the electric energy of the battery energy storage system in a photovoltaic power generation system. It converts the direct current generated by the solar panels into alternating current for power and stores the excess power in the battery so that it can continue to supply power when needed.
Main effect:
Solar power generation: Hybrid inverters convert the direct current generated by solar panels into alternating current for home, commercial, or industrial electricity needs.
Battery energy storage: The hybrid inverter is equipped with a battery energy storage system that can store excess solar power. When the Solar Panel cannot generate enough electricity, the electricity stored in the battery can continue to supply electricity to achieve a continuous power supply.
Grid-connected function: Some hybrid inverters also have grid-connected functions, that is, the excess electric energy is integrated into the grid for use by other users. This allows them to interact with the grid, be self-sufficient, and export electricity to the grid.
Differences from other inverters:
Charging control function: The hybrid inverter combines the functions of an inverter and a charge controller, and can simultaneously process the DC power of the solar panel and the DC power of the battery energy storage system, realizing the hybrid application of solar power generation and battery energy storage.
Standalone operation: Unlike microinverters, hybrid inverters can operate independently and do not require an inverter for each solar panel, so it may be more economical and convenient when the system is larger.
Applicable scenarios: Hybrid inverters are widely used in home, commercial, and industrial photovoltaic power generation systems, especially in hybrid application scenarios that require photovoltaic power generation and battery energy storage.
In general, the main function of the hybrid inverter is to convert the direct current of the solar panel and the battery energy storage system into alternating current, so as to realize the hybrid application of photovoltaic power generation and battery energy storage. Compared with other inverters, it has higher flexibility and reliability in energy management and power supply stability.
