Guangzhou International Lighting Exhibition 2009 — Chinese Manufacturers

GVO
Golden Valley Optoelectronics Co., Ltd (GVO) is a Sino-US joint venture based in Hebei, China. At the exhibition this year, the company showcased its multiaspect LED bulb which was awarded first prize in the illuminants category of China’s Electrical Lighting Product Prize.

The prizewinning product has 5 to 10 1W/3W LEDs packaged in a ring of light emitting source in the bulb to achieve 360-degree tridimensional lighting angle. The candle-type 1W bulb, for example, has a power of 1.7W and a luminous flux of around 90lm, with the illumination range approaching 4π, and the expected lifespan of 35 thousand hours. The main application of the product is to replace incandescent bulbs as well as crystal lamps in exhibition halls. However, with the evolution of LED technology, the competitiveness of the cost structure of this product remains a key focus.

Foshan Lighting
The traditional lighting manufacturer, Foshan Electrical & Lighting Co., Ltd was founded in 1958, and has been listed on Shenzhen Stock Market (000541). At the event this year, to comply with the energy-saving policies of Chinese government, the company introduced its LED-relevant lights as well as its traditional lights with high luminous efficacy, showing its resolution of stepping into the solid state lighting field.

Though OSRAM is its largest share holder, Foshan’s LED lights are completely different to that of OSRAM. Unlike the technology of OSRAM, Foshan uses low-power LEDs in its packaging. The LED bar exhibited at the show had 120 low power LED chips sealed into one package, intended to replace traditional T8 tubes, with lifespan said to reach 30 thousand hours (L60).

Luminglight
Luming Science & Technology Group was founded in October, 1994. Currently, the group owns four affiliated companies, including Dalian Luming Optoelectronics Engineering Co., Ltd, Dalian Luminglight Co., Ltd, Dalian Lumei Optoelectronics Science and Technology Co., Ltd. and Dalian Photonics Industry Park Development Co., Ltd.

Dalian Luminglight Co. Ltd attended the event this year. The company mainly sells phosphor and lighting products. However, besides phosphor, very few lighting products were seen at the company’s booth at the exhibition.

 

Jingri Lighting
