How to increase the duration of high-power LED driver

 

Essential as power devices, electrolytic capacitors must be able to long-term work in high temperature environment, this test is very grim. General-purpose aluminum electrolytic capacitor life span of only 4000 hours to 5000 hours, half life, and at high temperatures is far from meeting the requirements of the long life of LED lighting, and thus the aluminum electrolytic capacitor has become the bottleneck of the high-power LED driver. The structural design of aluminum electrolytic capacitors, the advanced nature of the manufacturing process to determine its service life. Aluminum electrolytic capacitors for LED lighting special emphasis on long life, high temperature and small.

 

The high-voltage driver chip may be one of the better solution HVLEDs constant current drive power. Some chips are ideal, but is too expensive to buy in China, used to produce general-purpose high-power LED driver costs are high. In recent years, China’s domestic integrated circuit design level rising, but there is a very good price and market competitiveness, to downstream manufacturers for the production of technical solutions and technical support in place.

 

In addition, the LED light source lamp bead is a major breakthrough. The rising star of the LED family of high-voltage LEDs (HV LEDs) have sprung up everywhere, the VF high voltage, the IF current working conditions completely subverts the traditional low-voltage (LV LED) LED VF low voltage, the IF current requirements. Led high bay lighting due to the HV LEDs SOP may reduce the shape of the heating, lighting structure may tend to be more to save cooling materials, greater than 270 degrees light-emitting, low-cost, light weight.
