High voltage LED with new trend in LED lighting industry1

2013 Since LED industry boom began to pick up a few years ago 5W of LED lights price is same brightness energy-saving lamps of 3- 4 times, however, in recent years, the price of upstream chips has dropped at a rate of about 30 per year, and the cost has generally dropped. By 2013, the price of LED terminal products will basically be the same as that of energy-saving lamps. LED industry is expected to enter the stage of fully replacing traditional lighting products. In recent years, with the awareness of energy conservation and the increasing demand for smart product displays, the prosperity of the LED industry has continued to rise. The industry generally expects that the LED market demand is expected to maintain rapid growth within three years. With the, China for LED lighting of related policies have been introduced many to export-oriented of enterprise will start moved to, China local market traditional lighting Enterprise also will have transformation LED lighting. The development of the industry is also accompanied by the continuous emergence of new technologies, among which high-voltage LED has become the focus of attention, and even some people think that it will make today's low-voltage LED fade out of the future LED general lighting market. the high-voltage LED will dominate the future LED general lighting. Mr. Zhang Lei, director of research and development of Jingtai photoelectric lighting, said: the generation of high-voltage LED originated from the idea of people going to the power adapter, allowing LED to work directly under alternating current. At present, high-voltage LED is divided into ACHVLED and DCHVLED. The former has no power supply and needs to be driven by mains supply. Under AC drive, it can integrate current control IC with stable electrical performance. The latter has the characteristics of high voltage and low current, which can effectively reduce the cost of power supply and improve the efficiency of power supply. It is suitable for high PF power supply driving scheme. However, PCT material is superior to the existing PPA in high temperature bearing capacity, reflectivity and UV irradiation. It can be used in large-scale outdoor LED display screen production and has good environmental adaptability. Dr. Shao Pengrui, director of photovoltaic technology at Jingtai, said: LED packaging technology will develop towards four directions, namely multi-chip integration, miniaturization, intelligence and standardization. High-voltage LED will be the future development trend of the industry, which can make LED work directly under alternating current. PCT high-voltage LED has brought brand-new choices to application manufacturers due to its advantages of sharp reduction in light source cost, simple design of driving power supply, low cost and easy heat dissipation treatment. in the future, the general lighting market will occupy an important place.
