Use of high-power light emitting side case: Chongqing Railway Station box, using our high-power light-emitting side lights, one meter 20 lights, reducing energy consumption, attractive appearance. The need for thermal management of high-power LED, which greatly increases the cost of the LED. In the design process, double-sided light boxes side-emitting light strip, is the most expensive additions fins. Fins may be made from a variety of metal materials that include both relatively inexpensive aluminum, but also more expensive but better conductivity material (such as copper and silver). These expensive materials may lead to increased cost of high-power product of $ 1 to 10, while the standard LED device can be avoided that the cost increases. Similarly, the need to use high-power LED MCPCB as another passive cooling techniques to control junction temperature. Because MCPCB material has better thermal conductivity side-emitting light bar prices, so compared to the standard LED used cheaper FR4 PCB, higher thermal efficiency of these boards. However, the costs are as much as five times the cost of FR4 PCB. Use cheaper FR4 PCB, to eradicate the need for expensive heat sinks, as well as simplify the design considerations, it can save costs up to 60%. 1. High-power LED spotlights structure, high power LED spotlight includes a housing, LED, PCB board, driver and base five parts. Shell is mainly responsible for the heat and protect the LED and the role of forming. High-power LED spotlights shell material in general are aluminum, good heat dissipation first side scrolling light-emitting lights, followed by quality lighter than other metals. Some housing LED lights for aesthetic side, but also on chrome and nickel-plated metal. High-power high-power spotlights, people often use the copper shell. Shell design is generally used on the sides fan design, which is around the housing body some blade extension installed, the main purpose is to increase the cooling area, to improve the cooling efficiency. High-power LED spotlights on the market with only two, namely 1W and 3W are two, there are fewer manufacturers use 5W and 100W to do, but because of the heat can not be solved, basically there is not much market. PCB board is used to power LED cloth placed side by side, while playing the insulation between the LED and the housing and the heat conduction to the shell effect. There are two PCB board on the market, one is for general power LED PCB, the other is suitable for high-power CREE LED PCB board. Side-emitting light boxes shelters, far illumination (certification), from the far side of the light lamps provide lighting Technology Limited. Far Lighting Technology Co., Ltd.
