Tue, 12/01/2009 - 4:10am

Cree, Inc (Nasdaq: CREE), a market leader in LED lighting, and Ningbo Liaoyuan Lighting Co., hosted the 2009 LED Lighting Fixture Promotion Conference last week in Guangzhou, China. The conference featured government officials and leaders from city street lamp management offices.

Liaoyuan Lighting and Cree jointly exhibited several lighting products based on Cree's LED technology, including street lamps featuring Cree's brightest and most efficient XLamp® XP-G LED components. This is the first time that

Liaoyuan Lighting used Cree XLamp XP-G LEDs in a light fixture. The XLamp XP-G LED delivers up to 132 lumens per Watt component efficiency, and enabled Liaoyuan Lighting to create a street lamp system efficacy of 98.3 lumens per Watt in a 150-Watt product. Liaoyuan Lighting is planning volume production of these 150-Watt street lamps to address the lighting needs of more Chinese cities.

Liaoyuan Lighting also demonstrated a 300-Watt street lamp that uses Cree XLamp XP-E LEDs. These lights are installed on Southern Guangzhou Avenue, a key 10-lane thoroughfare in downtown Guangzhou. The Liaoyuan streetlights demonstrate increased luminance and uniformity compared to the prior high-pressure sodium lights. Additionally, Guangzhou is reporting energy savings of more than 40 percent over the old high-pressure sodium lights, as well as better light quality.

Lin Zhengang, engineer of the Guangzhou Streetlamp Management Office said, "Energy-saving products are becoming increasingly popular in the current economy. The LED street lamps we installed enable us to not only enjoy beautiful light, but help us better meet our energy-efficiency and environmental protection goals. With the government's ever-growing demands for energy-efficiency and clean technology, we expect that such products will be widely used in our urban facilities."

Shao Yunwei, general manager of Liaoyuan Lighting said, "We are very happy to see a growing market demand for high-efficiency street lamps. Working with Cree, we plan to continue our efforts to produce more environmentally-friendly and more efficient LED lighting products."

Tang Guoqing, general manager for Cree China Sales, explained, "We are very happy to see Liaoyuan Lighting announce such remarkable achievements using Cree LED technology. We anticipate more and more energy-saving and environmental lighting products will be installed on streets throughout China. Cree has long made efforts to push the development of LED lighting, and continues to bring its latest products and technological advancements to the citizens of China."
