We wish to cooperate with every partner to contribute for promoting green lightings. In the current world, gradually resource exhaustion and environment labefaction brought great challenge to human being survival. The semi-conductor (LED) is known as the most energy-saving and environment conservative green light-source in the 21st Century. China and many countries have successively announced policies and regulations for promoting the new light-source. A revolution in the lighting field is spreading in the world. We have invested abundant human resource and material resource for developing the new generation LED semi-conductive lighting products. At present, these products finally come out. They only consume 20% electric power of the traditional light-source, but they can produce 80LM/W. They are 10 times brighter than the traditional light-source, with over 50,000 hours' ultra-long service life. Now, everything comes true through our great effort.
