As the core component of lighting products, light source has always been the focus of attention in the industry, and the performance of these light source product manufacturers is always the object of attention of the industry. In recent years, with the global economic recovery, production costs and prices have risen, and market profits have gradually become thinner. These have brought a lot of confusion to light source enterprises. Old-fashioned enterprises are facing the impact of new forces, and small and medium-sized enterprises are facing strong momentum. The brand reshuffle, the industry brand has evolved from a mixed period to a high standard, high quality, high demand brand era. In this process, energy-saving lamps have successfully entered the rural market, LED technology innovation needs to be solved urgently, the bracket light source fluorescent tube has entered the high-end brand cultivation period, and the new generation of electrodeless lamps shines in an efficient and energy-saving manner. This seemingly astounding market In the process, the breakout work of enterprises facing dilemmas is different. In this issue, we plan to focus on what challenges and opportunities the light source enterprises face in the new round of economic wave. How will they highlight the encirclement? And win the city
Light source theme energy saving and environmental protection
In recent years, with the rapid development of China's economy, the Chinese light source market has also grown rapidly. At present, a new industrial pattern represented by energy-saving lamps, LEDs, T4/T5 fluorescent tubes, and electrodeless lamps has been formed. These products have an obvious common feature, that is, energy saving and environmental protection. The formation of a new pattern of the four major product lines has made outstanding contributions to alleviating the global energy shortage. With the promotion of the “energy saving and consumption reduction†work, energy conservation and environmental protection are still important trends in future product development.
From the field of energy-saving lamps, 90% of the world's energy-saving lamp products are from China. At present, there are nearly 2,000 energy-saving lamp manufacturers in China, and the large-scale energy-saving lamp manufacturers are mainly distributed in Guangdong, Zhejiang, Shanghai, Fujian and Shandong. And other areas. Since 1996, a number of strong energy-saving lamps have emerged in the domestic light source market. Among them, the old-fashioned enterprises represented by Zhejiang Sunshine and Foshan Lighting have transformed themselves into new brand image and influence, and they have been in the early stage of this newspaper. It is clear from the survey results of the top 500 dealers that these brands have a good performance in the market. Secondly, the “emerging faction†represented by “small ghosts†quickly “surrounded the city by the countryside†and developed rapidly, pushing the first-line brands and even successfully compiling the first-line brands. Furthermore, the Shanghai energy-saving lamp company represented by Shanghai Luyuan has performed well in Shanghai's domestic market, but it is not active in other provinces in China. From the development situation in recent years, although it has changed, it needs further Work hard. In addition, Xiamen energy-saving lamps enterprises represented by Donglin Electronics are mostly export-oriented. In recent years, despite the serious impact of EU anti-dumping, they have actively carried out reforms. In addition to building production bases overseas, they have fought in the Americas. Outside the Australian and Southeastern markets, it has responded positively to EU anti-dumping and has also achieved good results. In addition, these export-oriented light source companies have also begun to stop at the domestic market, often represented by the foreign brand of TCP. In recent years, despite the embarrassing situation of “unacceptable water and soilâ€, its influence on the domestic market is not allowed by its strong brand advantage. Small vision.
From the perspective of LED field, China's LED lighting industry started in 2003. Up to now, it has formed four major regions in the Pearl River Delta, Yangtze River Delta, Southeast China, Beijing and Dalian. Each region has basically formed a relatively complete Industry chain. Up to now, there are more than a thousand LED companies in China, of which there are about 25 extension and chip manufacturers in the upper and middle reaches, and more than 1,500 downstream packaging enterprises and application enterprises, but the scale is generally more concentrated than the application of LED in the lighting industry. In the application of decorative lighting fixtures such as display screens, advertising light boxes, signal lights and guardrail tubes, the role of point light source and auxiliary lighting is more played, and there is almost no application in general lighting. This has been called "21". The social voice of "new century light source" and "promising to replace ordinary lighting" is quite different.
In the past two years, many LED companies have begun to invest in the research and development and production of LED lighting sources and lamps, such as Hong Kong Zhen Mingli, Shenzhen Lianchuang Jianhe Optoelectronics, Zhongshan Weilai, Fuchenglong Lighting, etc. . In addition, Jiangxi Jingneng Optoelectronics has carried out two rounds of financing of 50 million US dollars, which will be mainly used for the research and development of epitaxial wafer materials for semiconductor lighting. In this way, Jingneng Optoelectronics will become one of the few growth gallium nitride on silicon in the world ( One of the companies of LED epitaxial wafer materials, it is easier to avoid the patent encirclement of many companies such as Nichia and CREE, which has become a new way to improve the efficiency of electro-optical conversion and reduce costs in China. Moreover, Jingneng Optoelectronics uses silicon as the LED substrate, and the cost is only one-tenth of the cost of mainstream LED companies in the US and Japan. Such competitiveness will make its application products more easily popularized. At present, the companies involved in semiconductor energy-saving LED chips in China are Lianchuang, Fangda, Dalian Luming and so on. These core enterprises strive to form a complete industrial chain on their own technology and achieve a certain scale of production.
From the perspective of the fluorescent tube field, in recent years, the fluorescent tube brand has presented four forces. One is the “old tree sproutingâ€, and some established companies and brands have transformed themselves and transformed their brand image and influence, such as Buddha Photo and Nine. The second is “awesome after the birthâ€, some emerging companies are developing rapidly, and they are forced to become first-line brands and even successfully squeeze the first-line brands, such as Sidon, etc.; the third is “by specializationâ€, and some professional brands that are refined in the industry are becoming the leading brands. Afterwards, it gradually integrated into the development of comprehensive branding in the industry, such as the commercial brand leading brand NVC, the home leading brand Oup, etc. They all extended their development reach to multiple segments, integrating resources to build a comprehensive brand; fourth, “export to domestic sales†"A lot of companies that have done a good job in overseas markets have gradually turned to the domestic market to create a brand-divided domestic cake. Chenhui Guangbao is a fourth force.
From the field of induction lamps, the electrodeless lamp is a new type of light source product, which has broad market prospects such as high efficiency, energy saving, shockproof, long life, environmental protection and energy saving, no stroboscopic, good color rendering, no need for preheating and other remarkable features. More and more attention is paid to domestic light sources. Up to now, according to the characteristics of the electrodeless lamp, it can be divided into two types: high frequency electrodeless lamp and low frequency electrodeless lamp. Among them, high-frequency induction lamps are represented by Shanghai Hongyuan, while low-frequency induction lamps are Guangzhou Shichang? Danda and Shenzhen Greene. Due to its high-density technology content and unique patented technology, the electrodeless lamp must have certain scientific research capabilities. Compared with the production of energy-saving lamps and LEDs and fluorescent tubes, it has high barriers to entry and is difficult to imitate and product. The problem of homogenization. Moreover, as far as the current electrodeless lamp products are concerned, the products produced by various manufacturers are also different in terms of technology. Of course, the patented technology and high efficiency, longevity and other characteristics also bring high market profits for the development and production of induction lamps.

Micro inverter is a small inverter used in solar power generation systems, its main function is to convert the direct current generated by a single Solar Panel into alternating current. Unlike traditional centralized inverters, microinverters are usually equipped with one per solar panel, that is, each solar panel has an independent microinverter.
Main effect:
1. Individual control: The microinverter provides independent conversion control for each solar panel, which means that each solar panel can optimize its power output individually. This maximizes the power generation efficiency of the solar panels since shading or other influences only affect the power generation efficiency of individual panels, not the entire array.
2. Reliability: Since each solar panel is equipped with a micro-inverter, even if one of the inverters fails, the other panels can still work normally, thereby improving the reliability of the entire system.
3. Flexible installation: Micro-inverters are usually small and can be installed near solar panels without being concentrated in one location, so installation is more flexible and convenient.
Differences from other inverters:
1. Individual control: Compared with traditional centralized inverters, microinverters provide independent conversion control for each solar panel, enabling each panel to reach its maximum power output.
2. Fault isolation: The micro-inverter has the function of fault isolation. Even if one of the inverters fails, other panels can continue to work without affecting the operation of the entire system.
3. Installation method: The micro-inverter can be flexibly installed near the solar panel, and does not need to be concentrated in one location, so the installation is more flexible and convenient.
4. Applicable scale: micro-inverters are usually used in small-scale solar power generation systems, while traditional centralized inverters are suitable for larger-scale photovoltaic power plants.
Overall, the main role of microinverters is to individually control and optimize the power generation efficiency of solar panels and improve the reliability of the system. Compared with traditional centralized inverters, it has some advantages in terms of flexibility, fault isolation and applicable scale.
