The person in charge of the participating companies said that every time Gaogong’s strategic meeting to Zhongshan is based on the integration of cost-effective lighting sources and key components and accessories manufacturers in mainland China and overseas, the quality upgrade strategy further optimizes Zhongshan Lighting. Lighting raw materials procurement channels, in order to change the bad reputation of Zhongshan LED lighting products in the past "low price and inferior quality" as the starting point, to enhance the value added of local LED lighting companies.
Zhongshan LED faces industry "turning point"
According to statistics from the High-tech LED Industry Research Institute (GLII), in 2012, Zhongshan LED industry reached 27.6 billion yuan, second only to Shenzhen, becoming China's second largest LED industry base. In the past three years, the development speed of Zhongshan LED industry is much higher than the national average development speed. However, more than 95% of the local lighting companies are transforming LEDs. The number of newly established LED companies is very small. It is characterized by traditional lighting companies, LED output value has risen rapidly, and individual companies have all transformed LEDs.
Dr. Zhang Xiaofei, director of the High-tech LED Industry Research Institute, analyzed that 2013 was a key year for LED lighting, especially for indoor lighting. The price of LED products quickly approached the traditional lighting level, prompting the rapid application of LED lighting products in commercial lighting. This is precisely the strength of Zhongshan's finished products. However, Zhongshan faces a lot of problems.
The main problems are: the government has no actual planning, synonymous with "low price and inferior quality", pursues low-end products "price-performance ratio", small influence of corporate brand, weak strategic awareness in long-term development, weak technology, plagiarism and assembly, light research and development, quick success The profitability is low. Most of them are LEDs that have been transformed in the past three years. Most of them are small in scale, and there are less than 15 enterprises with an annual output value of over 100 million yuan. There is also the lack of a good supplier, the positioning of the company is not clear, and so on.
"Only focusing on the integration, optimization and upgrading of the entire industry chain is the foundation for helping the Zhongshan industrial base to take off." Zhang Xiaofei concluded.
Senior Industrial and Industrial Research President Gao Gong LED CEO Zhang Xiaofei Zhongshan LED industry should go where to go
We know that there are currently three major distribution centers in China's traditional lighting market: Zhongshan Guzhen, Linyi and Zou District. Under the impact of LED lighting, if we do not have clear positioning and scientific planning, if we do not transform well, we may lose our original status. It can be said that the pattern of traditional lighting will be greatly changed. What is the desire of Zhongshan LED? LED base? Accessories base? Manufacturing base? Export base? Still a low-cost product base?
In the future, if Zhongshan still does not change its market policy with low prices, a major crisis will occur and the national market share will decrease. LED lighting products have higher quality and technical requirements than traditional lighting products.
I believe that the Zhongshan LED industry must be upgraded from three levels. The first is the enhancement of the company's own strength, including positioning, strategy, management, products, capital, etc.; then the re-architecting and strengthening of the channel, while paying attention to the supplement of network channels, including quality, channel, and technology; The low-end brand image forms a three-tiered brand of high, medium and low, which is to achieve brand breakthrough.
Philips Lumileds Asian Marketing Director Zhou Xuejun chooses the lamp beads in multiple ways
The photoelectric parameters of the LED lamp bead mainly include light effect, luminous flux, color temperature, color coordinate, color rendering index, voltage and the like.
Since LED is a relatively new product, China's national standards lag, but the country provides product qualification tests. LEDs with international safety certifications (such as GS, CE, UL, etc.) and national product quality certificates are expensive because they are reliable in safety design.
According to incomplete statistics, more than 200 manufacturers of LED lamp beads (packaging equipment are better) are packaged in the Pearl River Delta. In addition, Taiwan, Europe, America and other places, LED packaging manufacturers are numerous, some LED lamp beads well-known brands, research and development The experience is relatively rich, the raw materials used, process control, and reliability are relatively guaranteed, but the price is high. However, the price of LED lamp beads of different brands varies greatly, and some prices even differ several times, but the quality is difficult to evaluate. If the quality is evaluated based on price alone, it is obviously unable to meet the reliability guarantee.
The cost of LED lamp beads using different chip packages is also different, and different brands of chips can not be separated by the naked eye. LED package manufacturers may appear to use small brand chips to pretend to be well-known brand chips. For LED lamp manufacturers, they need to be packaged. The manufacturer establishes a good cooperative relationship and examines the process of using the chip to ensure that the LED lamp bead of the chip package specified in the contract is purchased.
More importantly, during the test, the parameters of the lamp bead are detected by a relatively optimized standard.
Hongli Optoelectronics Engineering and Technology Center executive deputy director Wu Gan COB packaging is a major trend
I believe that the COB integrated light source has become the mainstream direction of high-power packaging. The COB integrated light source is similar to the LED point light source becoming a line light source or a surface light source. A single LED is made into a fluorescent tube light strip or integrated surface. When the light comes out, it passes. The matte mask is subjected to secondary optical processing to make the light more uniform. The COB light source can improve the glare problem. As an application end, the assembly is more convenient, but at the same time, the light efficiency and luminous flux of the device are also lost.
Of course, it is still necessary to distinguish from the market application. Incandescent lamps above 100 watts are about to be banned. With the increasing demand for high lumens light source applications, there is no way to cross the SMD package. This is because one is The area of ​​lighting fixtures is limited. The lumens that can be achieved with low power is limited. COB can meet the requirements of high power and higher lumens. The cost of the two COB packages is much lower than that of SMD packages. Because it not only has an advantage in heat dissipation, but also has a good performance in terms of price.
However, COB light sources still have many problems to be solved: First, the integrated package will reduce the light efficiency and light transmittance, and the wafer light efficiency and luminous flux can hardly reach a certain height. Second, whether the substrate technology can better solve the heat dissipation and heat conduction problems. Third, the packaging process, that is, the combination of the wafer and the substrate has a better thermal conduction process. Fourth, whether the epitaxial wafer is resistant to large currents, temperature, and quality is well done.
Li Zhaohua, deputy general manager of Ming Microelectronics, has three key points for optimal power drive configuration.
I think the best power supply design for LEDs must first consider the basic needs of customers, such as the type of lamp bead, power and application, performance requirements, including accuracy, efficiency, lumens, PF, etc.
Meeting these basic needs is only the first step, and more importantly, meeting the quality needs of customers. For example, whether it meets the relevant certification ------ certification will increase the cost; whether the reliability of the power supply product is up to standard ---- electroless, high integration, abnormal protection; whether the product temperature characteristics are suitable ----- -The temperature rises and the current decreases
Protect the luminaire system, work safer and last longer!
There is also the ability to achieve optimal cost, such as device selection ------ temperature characteristics, consistency; topology ------ inductance, transformer requirements; and production costs --- --- Batch, labor cost considerations.
Finally, I want to say that the best performance solution is not necessarily the best solution for customer needs; the best cost-effective solution for mass production - the best power supply design.
Industrial Energy Storage System
The main function of the Industrial Energy Storage System is to store energy in the industrial field to meet the energy demand in the industrial production process. It is an energy storage solution for improving energy efficiency and power supply stability in industrial production systems.
Main effect:
Energy peak shaving: Industrial energy storage systems can store energy and release energy at the peak of energy demand to meet the high energy consumption demand in the industrial production process. This helps to achieve a balanced deployment of energy and avoid energy waste or power outages caused by imbalances in energy supply and demand.
Reserve power supply: When the power supply of the power grid is unstable or there is a power outage, the industrial energy storage system can be used as a backup power supply to continue to supply the power required by industrial equipment and ensure the continuous operation of industrial production.
Energy saving and emission reduction: Through rational use of energy storage, industrial energy storage systems can optimize energy consumption and reduce energy waste, thereby achieving the goal of energy saving and emission reduction, and reducing the impact of industrial production on the environment.
Differences from other energy storage systems:
Scale and capacity: Industrial energy storage systems usually have large scale and energy storage capacity to meet the high energy demand in industrial production. Home energy storage systems, on the other hand, are usually smaller and are mainly used in home photovoltaic power generation systems.
Application scenarios: Industrial energy storage systems are mainly used in the industrial field to meet the energy demand in the industrial production process. The Home Energy Storage System is used in the home photovoltaic power generation system to improve the energy self-sufficiency of the home.
Control and management: Due to the large scale of industrial energy storage systems, their control and management require more complex and precise technical means to achieve efficient energy utilization and stable supply. Home energy storage systems are usually relatively simple and easier to automate and manage.
Generally speaking, the main function of industrial energy storage systems is to meet the energy demand in the process of industrial production, realize the balanced deployment of energy, and the stability of the power supply. Compared with home energy storage systems, it is different in terms of scale, capacity, application scenarios, and technical complexity. The application of industrial energy storage systems helps to improve the energy utilization efficiency of industrial production, optimize energy management, and promote sustainable development and green production.
