Mid-power LEDs performance in 2013 has been stellar. Mid-power LED has become the mainstream for interior lighting, including retrofit bulbs, remarked Sean Zhou, Asia Regional Marketing Director, Philips Lumileds during the LEDforum Taipei 2013. Large volume of mid-powered LED are applied in downlights and panels.. Indoor lighting applications for downlights and panels is hoped to turn to mid-powered LEDs in the future. The Philips Lumileds flip-chip high voltage currents and small sized packaging can achieve better luminosity (lm/w) and price/performance ratio (lm/$) through. The company plans to introduce flip-chip technology into the mid-power LED market in the future.

It is evident that mid-powered LED product line is drawing most attention from the market this year. Zhou pointed out mid-powered LEDs have become mainstream for interior lighting and is already largely applied in retrofit bulbs, downlights, and panels. Mid-powered LEDs can even be seen applied in outdoor lighting, there are cases of the product being used in street lights now. It is still unclear as to whether mid-power LEDs or high-powered LEDs will become the mainstream because different lighting fields require support from different power products.

Philips Lumileds plans to introduceflip-chip technology to mid-powered LEDs in the future. The first chip-scale-package product LUXEON flip-chip by Philips Lumileds made the package size nearly equal to the size of the chip. Reducing the size of the package is conducive towards increasing flexibility of application designs, and can reach a better luminosity (lm/w) and price/performance ratio (lm/$) performance through high voltage currents and small sized packaging.

The company’s LUXEON flip-chip use of inverted CSP technology can omit the wiring process. This not only allows the product to achieve high voltage and at the same time reduces package size, while increasing package density. Philips Lumileds is optimistic about the flip-chip’s advantages in luminosity efficacy, lm/$, and package size. The company plans to use flip-chip technology in mid-powered LEDs.
