Taiwan LED standard lamp efficiency, the requirements difficult to achieve

LED energy saving applications push the trend to accelerate expansion. Not only the screen | display devices and lighting applications demand growth potential of high-profile product applications consumer goods such as toys, stationery, general lighting, etc, so the long-term development of LED industry, space and dynamics. That lighting LEDs and traditional light sources due to the difference in cost is still high, the expected popularity of LED lighting in general have 2-3 years of preparation, but the lighting of public works, such as LED lamps, energy savings in the policy advocate, has the first opening. Taiwan's "Ministry Economic Affairs Bureau of Standards of proof "has also recently completed the development of LED lights, but the measurement time required for reach 4.000 hours, expect the list of qualified suppliers will be the fastest in the oven the first quarter of 2009.
China launched in 2008 between the various energy saving projects LED lighting show, the potential business opportunities for LED brightness. "Taiwan Ministry of the Office of Economic Affairs Testing standards "to allow public and private procurement of LED lights in shape, but with special reference to the Office of Energy research model set of specifications for LED lighting products, technical office ruled the LED lighting standards and quality of plan research and development of integration applications announced by the five types of industry standards, and guidelines regarding the technical data, industry, government, academia, research co-operation from all walks of life, in early December 2008, officially announced rules CNS15233 LED lighting of the road.
Although some manufacturers of LED lamps, said the "Bureau of Standards," established standards, requirements on the effectiveness of LED lights is harder to achieve between. LED lamps light after the completion of dry-based (1,000 hours), as normal continuous light at 3000 hours, the beam to maintain the rate of not less than 92% and luminous efficiency not less than "Bureau of Standards, the standard value. The characteristics of the LEDs, which produce light with time and temperature decrease, and therefore, how the LED lights up 4000 hours, still maintain a certain luminous efficiency, is where the difficulties.
On the other hand, companies that glows in the durability test, the product must at 50 ° C ± 2 ° C environment for 360 hours of continuous operation, after the end of the experiment to measure the luminous flux value. In the high temperature reliability testing LED street lamp, and is also a great challenge for manufacturers.
However, despite the manufacturers in product standards, there are many to be exceed, government agencies have the lead in promoting energy conservation projects, energy saving LED lighting applications for these opportunities to get to the foreground. Manufacturers with a clear business, manufacturers to improve their products will accelerate R & D, equivalent to learning by doing amendment to promote the use of LED street lighting is to overcome obstacles and accelerate the product increase the spread.
Among them, the Taipei City Government selected the 228 parks and 52 roads around all LED lamps will replace the original 250 watt mercury vapor lamps of 125 watts of engineering LED lamp has been completed by mid December 2008. The device LED lamp specifications produced by the Industrial Technology Research Institute and assistance manufacturers, and its brightness, lighting and standards are in conformity with the regulations. Is expected to be as high as 52% energy efficiency, cost about 250 million New Taiwan dollars. In addition, the Taipei City Government in 2009 replaced the light of great parks and 200, an LED light switch is expected to pass NT six million yuan. About the Author
