"Make the LED lighting system more convenient" to visit the LED power module

Set the example LED lighting on the rise, the market is expected to expand. New LED lighting business involved in a lot of companies, with the expansion of the scope of the manufacturers involved in the hope that the demand for simple design of LED lighting devices continue to increase. GmbH (RECOM Electronic) engaged in the power module business to meet this demand is stepping up the expansion of LED driver module product line. In addition to the LED lighting power supply with small DC-DC converter LED driver module, the company also launched in the second half of 2010 can be directly used commercial AC power to light LED lighting AC-DC converter LED driver module. The day before, the reporter on the company's product features and development goals, interviewed Li Kang Asia Pte Ltd (RECOM Asia Pte Ltd.) Greater China, Hongkong, Taiwan and Japan sales director Harry Gu, and RECOM Distribution & Logistics GmbH Karsten M. Bier group managing director.

This module is only connected to the power supply line and the LED module. 20W output products on the left side of the 12W output products, the lower side of the 60W output products.

What are the features of the LED driver module? Li Kang: we have been for industrial equipment, such as the use of high reliability requirements to provide power modules. LED lighting is a promising market in the future, so we started about 3 years ago for LED lighting in the product line to increase the drive module for the LED light. Although the first is from the DC input LED driver module began, but with the hope that the AC input to light up the voice of LED is increasing, we will put the market into the AC input LED driver module.

It can be said that both the DC input of the product, or AC input products, our products are able to light up the various manufacturers of the LED concept. We and the United States Bridgelux (BridgeLux), CREE (Cree), Taiwan (Everlight), photoelectron billion Germany OSRAM Opto Semiconductors (OSRAM Opto Semiconductors), PHILPS (Philips Lumileds), and lumen (Seoul Semiconductor) Seoul semiconductor has a partnership, they adopted the company's LED in the reference design driver module.

- talk about the timing of the LED drive's ease of use. Kang: for example, the DC input of the LED driver has only 6 terminals. 2 for the input power, the 2 for the output power to the LED, and the other for the dimming of the PWM input uses for. Can achieve 0 ~ 100% dimming. While other companies of similar products only 10 ~ 100%. In the case of lighting designers, sometimes 10% is too bright.

By extending the dimming range, the design of LED lighting fixtures can be extended. LED progress with each passing day, there will be a variety of luminous efficiency and brightness of 1 years to improve the LED new products unveiled. Every time a new LED, it will be necessary to re design of LED lighting. And through the use of dimming function, it can reduce the trouble of re design.

- please talk about the requirements of the AC lighting LED to enhance the background. Kang Kang: it can be said that the use of incandescent bulbs and other light sources have been designed for the design of lighting devices, there are a lot of people until about 2 years ago, do not know the need to drive the light LED. Although there is no such thing, but can not say who are good at power design. Use the DC input LED driver module can be easily lit LED, but to drive module input AC power to the LED, also need to prepare for the AC-DC converter, so that the power design of the lighting fixture design staff is a troublesome work.

To save this trouble, the simple assembly of LED lighting system is the AC input LED driver module. The power supply line of the commercial power supply is connected with the power connector of the LED driving module, and the output of the LED driving module is connected with the LED module, and the system can be used for lighting. The efficiency of the input connector is more than 90%, and the power factor of the power factor correction (PFC) circuit is as high as 0.95. Judging from the thickness of the module, the output of the 12W product is only 18mm, 20W output products only 22mm, so it can be easily set up in a limited space.

Provide 5 year warranty for reliability. Our company has been engaged in the power supply module of industrial equipment, so we have the know-how to obtain high reliability. In LED lighting appliances, the power supply circuit determines the life of the product. Once the power circuit is damaged, even if the LED has a longer life, it can not play its expertise.

Our AC input LED driver module does not yet support dimming function, but has plans to launch in 2011 to support the market dimming products. Intends to launch the first output power of 12 ~ 20W varieties.

Sales of AC input in Japan, the first to comply with the requirements of the Japanese Electrical Products Safety Act (PSE) requirements. Are they certified? Li Kang: we are ready to apply for PSE certification of written materials, has been submitted to the relevant certification bodies. Is expected to be adopted in the mid 2011. In addition, the company also received the UL standard LED lighting as the object of the safety standard UL8750 certification.
