Cree and Liaoyuan demo 98.3lm/W LED street light

At last week’s 2009 LED Lighting Fixture Promotion Conference in Guangzhou, China (featuring government officials and leaders from city street lamp management offices), co-hosts Cree Inc of Durham, NC, USA and Ningbo Liaoyuan Lighting Co Ltd of Zhejiang Province, China 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 has used Cree XLamp XP-G LEDs in a light fixture.

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

Liaoyuan Lighting also demonstrated a 300W 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 street lights are said to demonstrate increased luminance and uniformity compared with the previous high-pressure sodium lights. Guangzhou is also reporting energy savings of more than 40% over the old high-pressure sodium lights, as well as better light quality.

“Energy-saving products are becoming increasingly popular in the current economy. The LED street lamps we installed help us better meet our energy-efficiency and environmental protection goals,” says Lin Zhengang, engineer of the Guangzhou Streetlamp Management Office. “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,” he adds.

“Working with Cree, we plan to continue our efforts to produce more environmentally friendly and more efficient LED lighting products,” says Liaoyuan Lighting’s general manager Shao Yunwei. “We anticipate more and more energy-saving and environmental lighting products will be installed on streets throughout China,” comments Tang Guoqing, general manager for Cree China sales.
