Currently, Taiwan’s LED lamp makers take an active part in contracting with 7-Eleven of Japan’s plan to offer LED lamps instead of traditional lamps at all of its stores in the districts that connect to electrical grids run by the Tokyo Electrical PowerCo.

The chain which estimates the LED lighting project to save around a quarter of electricity spending in the quarter from July this year will cost about 10 billion yen to outfit 5,000 of its stores.

Taiwan’s LED-lamp makers including Ledtech Electronics Co., Ltd., Genesis Photonics Inc., and Unity Opto Technology Co., Ltd. are seen to be contracted to supply the lamps. Up to now, Ledtech has succeeded in tapping supply.

It’s estimated that around 28 million convenience stores are projected to use LED-lit freezers in four years beginning 2010, up from 16 million convenience stores in 2009 around the world.

Since Japan earthquake, Unity Opto has received an increased number of LED-lamp orders. As a result, it will help promote the company’ sales for this month and next. And according to Genesis Chairman K.R. Chung, his company began partnering with JFE Engineering Corp. of Japan last year. Office buildings, factory buildings, roads and transportation stations provided by enterprises and government are mostly targeted by the two companies this year.
