Acriche Semiconductor Light Running From Your Home’s AC Power

Brightness Improved by 50%, Price Lowered by 40%

(PresseBox) (Korea, ) Seoul Semiconductor (KOSDAQ; 046890), the eighth-largest LED manufacturer in the world, announced today that it simultaneously has released a new package type of Acriche, the semiconductor light with brightness of 200 lm all over the world such as in the US, Europe, and Japan. The brightness is 200 lumens at 3.3 Watt, nearly 60 lm/W, improved by 50%, compared to the previous version released last November, while the price is lowered by40% thanks to high production capability and its advanced high-yield device fabrication methods.

Acriche is the world-first semiconductor light, directly plugged in general homes and offices’ AC power for 110 or 220 volts without an AC-DC converter. Acriche is Seoul Semiconductor’s own patented product discriminated from other conventional LEDs and its patents were registered in the major countries for LED such as in Korea, the US, and Japan. Seoul Semiconductor is cooperating for Acriche with Nitride Semiconductor in Japan. Acriche is better than glow and halogen lamps in terms of power efficiency and brightness, and outpaces fluorescent lamps in terms of life span, power usage and convenience and it can replace these lamps. This release will make a great change from conventional light such as fluorescent and glow lamps into semiconductor light.

Also, it is expected to be rapidly commercialized for the general lighting applications such as downlight and MR 16, broadly used for architectural interior, as only one Acriche package can be used in 4-watt level of high power. Besides, it can be used at 100~110 or 220~230 Volts, and the demand in the countries using 220-Volt level of voltages, such as Korea, EU, China, India, the UK seems to be increased.

Seoul Semiconductor sells this Acriche’s new version as a single emitter. That is to say, Acriche sells as an emitter without a heatsink PCB, and this will broaden the range of application for Acriche even more as lighting fixture companies will be able to make the PCB type they need and array emitters on the PCB.

“Lifespan of Acriche, which will replace conventional LEDs, is much longer than conventional LEDs. It doesn’t need an AC-DC converter, which costs 5 dollars for 5W in general, and can save cost and space. What is more important is that Acriche can directly replace them, while DC LEDs can’t directly replace lighting fixtures for the architecture and machinery lights running from AC power. Acriche’s share of the conventional lighting market has the potential to reach tens of billions of dollars,” said Do Hyung Kim, head of the Acriche unit at Seoul Semiconductor.

Seoul Semiconductor is planning to increase Acriche's brightness from the current 60 lm/W to 80 lm/W with the package of 250 lumens by the fourth quarter of 2007; and to 120 lm/w with the package of 400 lumens before the end of 2008. It is expected to replace about $100 billion of the lighting market all over the world.

On the other hand, the power usage of Acriche lighting is much less than conventional lighting and, Acriche has a great effect of environmental protection. If replacing incandescent and fluorescent lamps used in Korea with Acriche, it is expected to reduce approximately 5.3-billion dollar annual electricity of 5 plants of million kilo-watts and 0.8 million tons of CO2 emission of 5 power plants. This is in line with global movements to reduce CO2 emission generated in power plants, the countries like US, Australia, New Zealand, and Cuba proposed or passed legislations to replace incandescent lamps with better efficient lights. Acriche doesn’t include hazardous materials and its brightness efficiency reached the level of fluorescent lamps, it is expected to be in attention as a green product compliant with the global trend of environmental protection.
