Cree, Inc. 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.
