Driven by policies and the long-life effect of LED lamps, LED lighting entered an outbreak year in 2013, and what will come after the outbreak is bound to be a gradual decline in the market, according to the lighting market share report of HISResearch, a market research organization, the sales volume of lamp sources has declined year by year since 2015. According to a report released by IMSReserch on April 2012, the price of LED lights will often go down by US $30 in 2009 and will exceed the US $5 mark around 2017. The popularization process of LED lamps depends on the decline rate of their prices, and the 40 cost of LED lamps is spent on driving control circuits, so the cost reduction of control circuits including LED driving IC is crucial. With this relative should be of IS drive control circuit cost will be in 2013 to 2015 between is expected to reduce 36. Although the LED driving power supply has made some breakthroughs in technology, the cost has been maintained at about 200 yuan. If the sales price is less than 400 yuan, it is basically in a loss State, however, foreign manufacturers such as Philips can achieve about 180 yuan at low sales prices. With the increase of labor cost, rent, marketing and office cost, it is quite difficult to reduce the price of LED drive power supply, and many enterprises have to fill the cost pressure from technology and design. To simplify the topology and reduce the price, we must optimize the structural design while continuously upgrading the technology and greatly reduce the number of IC components. In the 9th LED general lighting drive technology seminar held in November 25, guo Chunming from PI pointed out that to reduce the cost of LED bulbs, it is necessary to change the LED driver technology. In the report, Guo Chunming pointed out that with the progress of LED drive technology, the conversion from two-pole driver to single-stage driver technology can reduce the cost demand of drivers, however, in the selection of available topologies for currently available LED drivers, non-isolated drivers are more likely to be used. He also mentioned that the buck converter used in the topology is small in size and uses low drain- The source voltage stress and the number of filter elements used are small, so it has the advantages of high efficiency and good EMI performance, compared with the topology of flyback and unipolar PFC combined with constant current flyback, its cost is low. Guo Chunming also listed the relevant requirements for low-cost bulb drivers, such as the use of possibly small heat sinks to achieve high efficiency, input high voltage and low voltage, it is necessary to meet the consumer lighting requirements of the European Commission's environmental protection setting directive and energy star, and to use step-down and step-down methods- The boost topology and EMI filter circuit are as simple as possible to achieve a small number of components, use a small number of LEDs to meet the low brightness standard and reduce the temperature stress of the heat sink to ensure in the production process. output constant current. Reducing the cost of LED drivers through topology is only an optimization in design for enterprises. Strict control of specifications and parameters is the key factor to ensure product quality. High-efficiency drivers can be realized through simple setting, and the set specifications need to be accurately grasped. Excessive specification design will lead to an increase in product cost; In terms of saving assembly costs, functions can be integrated as much as possible to reduce circuit board space; The use of good design can meet the needs of consumers with a small safety margin. High voltage linear constant current technology, high voltage linear constant current power supply has no magnetic devices such as transformer and electrolytic capacitor, which can save 1/3 of the cost of general switching constant current power supply. Due to the simple structure of the system, only a few peripheral components are needed, which is suitable for systems with volume and cost requirements. With the emergence of HVLED lamp bead technology, non-isolated high voltage linear constant current LED driving power supply technology has become a new hot spot for LED light source driving. Professor Yan Chongguang of Shanghai Microelectronics Research Institute of Peking University also showed the integrated photoelectric engine driven by HVLEDs high voltage linear constant current at the LED general lighting drive technology seminar: the driving power chip and LEDs lamp beads are placed on the same side of the copper-aluminum substrate, which facilitates the automatic production of SMT. The power supply has no transformer and electrolytic capacitor, and the production cost is low. In the high-voltage linear constant current scheme displayed on site, there are no magnetic components, no EMI filtering and built-in high-voltage power tubes, which can be used to design and produce integrated photoelectric engines. However, this technology also has its limitations, and has not yet been able to solve the problems of stroboscopic, PF, voltage regulation rate and so on, which need to be improved and solved.

Now the use of LED lights have been gradually becomes widespread, more and more people are using the LED street light, LED light source in many people's eyes became the symbol of energy conservation and environmental protection, in the later use process need to be more optimization of such products, convenient people's life! LED lights use the advantage is to have a lot of, in the northern places can show more, in the north in winter, for example, in many places due to the problem of lamplight, interfere with the driver's line of sight, a lot of accidents, and here, the LED street lamp manufacturer to tell you that snow, LED street lamp is the most should be used. LED lighting lamps system design with the appropriate level and light screen brightness, can provide excellent in snow conditions for the driver object detection and contrast, reflection of light scattering in the snow-covered road performance can increase the brightness and light up the road. So the question comes, with the LED not snow melt and so the LED street lamp is the ideal choice for traffic and street lamp? LED street lamps and lanterns is usually horizontal orientation of the optical system, the ice and snow, if the lighting design is reasonable, the interference almost won't be a problem for more industry information or ask price, can call advisory

Explosion-proof lamp light source first choose is energy-saving lamps or incandescent lamps, this also is to the best of the current development of the light source adopts, and on the degree of understanding and mastering the led is relatively low, but now with the development of led technology and familiar with the manufacturer of led, led lamp went into people's horizons, just like that. Use led lamp, light source, such as the reliability of the protection. Explosion-proof lamp shell, is now mainly adopts aluminum alloy shell, through die casting molding. Because be explosion-proof led lights, so the structure is to meet the requirements of the national standard. Led lamp driver is the key elements affecting the service life of lamps and lanterns of the whole lamp, now on the market there are a lot of drive manufacturers have, known as the 5 years, 10 years, the actual use of the internal electronic components, the design scheme is the same, plus some production manufacturer lax, ultimately deceive users. Our lighting is to choose the brand of the led driver, joint the user's requirements, choose different materials, different warranty time, different scheme of the led driver.

In 2014, Shenzhen Jiawei Photovoltaic Lighting Co. , Ltd. (Hereinafter referred to as Jiawei shares) Its LED lighting brand, maixing lighting, has returned to China and has quickly become a dazzling new star, attracting extensive attention from all walks of life. So what will happen in the future? For this reason, we interviewed the president of Jiawei shares, maixing lighting (MAXIMUS)Brand founder Mr. Li Wei. Taking advantage of the mobile Internet and seizing the opportunity of development, China's lighting brand-free seems to have become an insurmountable barrier for domestic LED lighting. Because of this barrier, many domestic lighting companies are blocked from entering foreign markets. The outside world believes that China's lighting has no brand, to a certain extent, it also shows that China's LED lighting market products are seriously homogeneous and innovative technology is not strong. I don't agree with this statement. China's lighting is not without a brand, but without an international brand. For example, some Chinese lighting brands such as NVC and Opal have done very well in establishing industry brands, which are worth learning from many LED manufacturers in China. In recent years, one of the best LED lighting brands in China has been expanding overseas markets, but their products have not completely gone abroad and have not yet formed a certain influence on overseas markets. In this regard, Li Wei expressed different views. After domestic enterprises go abroad, how to compete with international enterprises, the establishment of brands is very important. President Li Wei pointed out that the brand must be rooted in the main products or services of the company. Whether it is a company that provides products or a service company, customers will form an understanding and cognition of the brand in the process of using the product. Brand construction needs time accumulation and needs to be truly implemented in specific products or services. At the same time, in the process of operation, LED enterprises must fully present the value contained in the products and do it so as to accumulate brand value and brand reputation. build up customers' trust in the brand. In the process of brand promotion, LED enterprises can speed up the establishment of brand awareness by means of promotion skills on the basis of ensuring products and services. At present, LED technology reform has brought different attributes and characteristics to the development of traditional lighting industry and the operation of enterprises. LED lighting products have strong electronic properties. From the perspective of product development and marketing, lighting enterprises should learn from the development experience of the electronic industry to help enterprises achieve leap-forward development. In addition, the Internet and mobile Internet have had a profound impact on people's lives. For practitioners in the lighting industry, they should pay attention to the development trend of the internet and find the key points that can be combined with the Internet. using the characteristics and attributes of the Internet to develop LED products, business operations, product sales, etc. In the lighting era, technological changes are rapid. LED lighting products have strong electronic product attributes, which is one of the prominent features of current LED lighting products. In addition, the mobile Internet has had a profound impact on the lighting industry. Lighting enterprises should conform to the changes, take advantage of the industry development trend, start the brand, and realize the leapfrog development of enterprises by seizing the development opportunities. Li Wei said so.
