[Source: High- tech LED " LED Good Products" magazine September issue reporter / Zhu Chunwei] Road lighting is closely related to people's production and life. With the acceleration of urbanization in China, LED street lights have directional illumination, low power consumption and good drive characteristics. The advantages of fast response, high seismic capacity, long service life, and environmental protection have gradually entered people's field of vision and become the world's new generation of energy-saving light source that has the advantage of replacing traditional light sources.
According to statistics from GLII, GLII statistics show that in 2012, China's LED street lamp shipments were 1.35 million baht, up 98% year-on-year; of which exports were 350,000 baht, accounting for 26%, a year-on-year increase. 132%. GLII expects shipments of LED street lamps in China to reach 2.31 million baht in 2013, a year-on-year increase of 72%.
In terms of actual installation volume, the installed capacity of LED street lamps in mainland China reached 1 million baht in 2012, an increase of 89% year-on-year. As of the end of 2012, the number of LED street lights installed in mainland China reached 1.95 million.
The demand for LED power drivers in such a huge market is also huge, and many companies are eyeing this big cake. Due to the harsh environment in which street lamps are used, their requirements for power supplies are also strict. According to statistics, 80% of the LED lights in the early damage are caused by the driving power. The life of the power supply is directly related to the use of LED street lights.
With the advancement of power technology, the current LED power supply at the theoretical level can fully adapt to outdoor street lights. However, from the problem of LED street lights that are constantly exposed everywhere, there is still much room for improvement in the design of power drive structures.
"What we are doing now is to improve the LED power supply drive structure to achieve high life expectancy and low cost, and promote the popularization of LED street lights." Shenzhen Antoshan Technology Co., Ltd. (hereinafter referred to as "Antoshan Technology") executive vice president Liu Qiang said, “It is our goal to give customers peace of mind, peace of mind and peace of mind.”
Traditional LED street light power supply
The traditional LED street lamp power supply adopts the AC power supply grid. On the one hand, it is greatly affected by the power grid. For example, the EMC impact of the power grid on the luminaire and the lightning strike caused by the power grid; on the other hand, each LED luminaire needs EMC, rectification, and power factor. Correction, filtering, power drive, inverter buck, steady voltage output or re-stable output to the LED source. The luminaire control device has complex circuits, many components, and high lamp cost. And relatively speaking, the safety and EMC problems are more prominent, which makes the reliability of LED lamps low and affects the life.
