Kyushu optoelectronics to participate in the trial of the Hongkong Metro LED lighting project

Hong Kong Railway Corporation Limited (MTR: Mass Transit Railway) is preparing high brightness LED lamp installation of environmentally friendly and energy-saving in the subway train and the platform, expand the scope of the trial of high brightness LED lamp, as part of its commitment to environmental sustainability and good environment.

Hong Kong Railway Corporation Limited operating engineering director Jacob Kam said, "these new LED lamps in addition has the characteristics of environmental protection and energy conservation, they have other advantages", "the LED light and natural light, and can provide a comfortable environment for passengers, especially those passengers who read books and newspapers."

2006 high brightness LED lamps for the first time in the subway train trial. Despite positive feedback from passengers, there is room for improvement in light efficiency, reliability and light color. Jacob Kam also said, with the progress of science and technology, high brightness LED lamps light efficiency and reliability should also be able to meet our service needs."

Therefore, Hong Kong Railway Corporation Limited and through a joint venture, experts in industrial lighting electronic Co. Ltd (Kyushu, Kyushu Electric Group), high brightness LED application of Hongkong subway train has been further improved, and Kyushu optoelectronics Co. Ltd. was obtained from the Hong Kong University Science & Technology (HKUST) technical inputs. Improved technology to enhance the reliability of LED lamps and light quality characteristics, making the color of LED closer to the natural light color.

Each lighting device is made up of 64 separate high brightness LED chips, which are installed on the three MTR trains. The first train starts running at Line Wan (Tsuen). Another two trains will run in June 2009.

Jiuzhou optoelectronics Co. Ltd. undertakes most of the project work, including detailed project plan, thermal and optical design, LED design, lighting device, anti vibration design of LED driving circuit design, including the installation of LED device on the train.

In addition, Kyushu optoelectronics Co., Ltd. will also be the first time the use of high brightness LED lamps test site. In the MTR Rainbow Station (Choi Hung Station) test, the lighting technology has been able to achieve daily lighting. Installation work is expected to be completed in August 2009.

It is estimated that, compared with the traditional fluorescent lamp, the new high brightness LED lamp consumes less than 30%, and the service life of up to 50000 hours, is the traditional fluorescent lamp 3 times, thus reducing the waste. In addition, when a high brightness LED chip problems, can be replaced individually, thus reducing the more waste.
