"Three noes" LED incoming LED lighting enterprises how to meet (two)

LED high temperature burns is the direct cause of occurrence of depreciation, shorten the service life of the lamp, lamp and related electronic equipment is also a source of instability, has become a major bottleneck for the development of the industry. To solve the problem of heat dissipation lamps, LED production costs will increase the number of disguised.

In order to ensure the normal operation of the LED and the life of the premise, improve the efficiency of light and reduce the cost of heating devices due to the increase has become the focus of the lighting factory.

The heat dissipation of the LED includes two processes, the internal chip to the heat conduction part of the substrate and the cooling part of the substrate to the external radiating device. "Internal heat conduction is not resolved, the other is on paper. Jian Yucang said that the latest research and development of their company's hot separation technology to improve the performance of COB packaging has improved significantly, but also greatly reduce the production costs, but can not completely remove the heat. Now LED thermal conversion of about 30% or so, the future when the LED chip and packaging technology has been greatly improved, all the energy can be converted into light, it is really no heat of the era!

No power, LED real revolution

LED lighting is known as energy saving, intelligent, long life, but these are basically to rely on a good driving power to achieve. The industry has been in the "100 LED lamp is broken, the 99 is the driving power of the problem", see the importance of LED driving power, which also makes it occupy an important position in the whole production cost in LED.

The LED lamp to the price, in the driving power supply is used to There is much fineness in the power supply in recent years is widely mentioned, even some people call it a revolutionary change LED.

Currently the main design ideas to power supply AC-LED and HV-LED. AC-LED because of its rectifier bridge is part of the LED combination design, part of the bridge is also part of the lighting, its advantage is that the volume can be designed very small. The new generation of special topology AC-LED light source can be directly driven by the alternating current (AC), which is becoming more and more mature, and will create a new era of LED lighting technology.
