Electronic information

771 developed in the efficiency of aircraft up to 95% of the power LED driver

In Electronic Infomation Category: R | on April   27, 2011

Recently, the China Aerospace Science and IRF520 datasheet and Technology Corporation Hospital 771 Nine Power Division to drive the circuit as a breakthrough, high-reliability design is complete constant current power supply, and IRF520 price and achieved significant results stage. Although the life span of LED lighting is generally more than 5 million hours, but with matching drive power is only 10,000 hours life around, unable to match the LEDs life, becoming one of the bottlenecks restricting LED lighting. Section Xiaofei

to the project team for the responsible person for driving power through a single wizard, is subjected to high peak current characteristics, combined with its turn-on threshold voltage and IRF520 suppliers and V / I curve, designed a new LED driver circuit, all the semiconductor devices and resistors. Life of the drive circuit and the LED to match the efficiency up to 95%, much higher than the existing 85% LED drive efficiency, and the circuit power factor greater than 0.97, better than the 0.9 target industry requirements. In size, because the technology is not required for transformers, inductors, electrolytic capacitors and other large device size and weight, the same drive circuit power is only one-tenth the volume of conventional circuit about drive and light easy to implement integrated design.

Currently, 771 Power Division has been completed using this technology to develop energy-saving fluorescent lamp T8 series of two models, developed integrated optical completed the 30W light source for light, 90W integrated photovoltaic street light, LED lighting applications field has made a breakthrough.
