Japan launched the life of up to 100 thousand hours of LED power supply

Japan's Kaga Components Co Ltd (Kaga Components Co Ltd) on the day before the LED/OLED held in Tokyo Lighting Technology Expo exhibition, showing the power supply equipment of LED lighting, the life more than 100 thousand hours. The device is still under development and the first appearance in the exhibition. As the electrolytic capacitor is removed from the circuit, the life span is longer than 100 thousand hours, and at the same time, the circuit size of the power supply can be reduced.

LED lighting is expected to grow rapidly in the near future, because people are increasingly concerned about environmental issues. But even as the main parts of LED lighting LED life of 30 thousand to 40 thousand hours, the existing power supply equipment of life is only 10 thousand hours, Kaga Components spokesman said, the main reason lies in the electrolytic capacitor has a lifespan of 10 thousand hours.

"We can not disclose the details of the circuit configuration, because the patent is still under review, but we remove the electrolytic capacitor to improve the switching power supply circuit configuration. "Kaga Component representation. With this improvement, the circuit size of the power supply can be reduced. The appearance of this power supply device is 43 x 29 x 8 mm.

The power supply device can be used in one to five series connected LED (one to five LEDs), the input power of 100V and series-connected (200V). The maximum output power is 20V DC 300mA, which is equipped with on / off control function and output short circuit protection function.

The company offers two types of output / input types: independent and non independent. The price of this product "depends on the size of the demand, about 500 to 600 yen, almost equal to the price of existing products. "According to Kaga Component representation.
