LED lighting applications: opportunities and challenges

These are the lighting requirements for green buildings. Policy benefits in the development and Reform Commission [2013] [Department] [188] semiconductor lighting energy saving industry planning, the text mentioned: gradually increase financial subsidies to promote LED lighting products. In commercial lighting, industrial lighting, public lighting and office areas, focus on the development of LED lamp, lamp etc. application demonstration and promotion of indoor lighting products and systems.

With the progress of urbanization, is expected to "12th Five-Year" at the end of the urbanization rate will be more than half of the new construction area reached 40~50 million square meters, and more than 20% of new buildings will reach the standard of green building, and a large energy saving green building requirements for lighting and electrical.

China's LED lighting industry can seize this opportunity, LED lighting can be any combination of light, flexible control, color rich and realistic features, combined with intelligent control to play a more effective energy saving LED.

These are the lighting requirements for green buildings.

Policy benefits in the development and Reform Commission [2013] [Department] [188] semiconductor lighting energy saving industry planning, the text mentioned: gradually increase financial subsidies to promote LED lighting products.

In commercial lighting, industrial lighting, public lighting and office areas, focus on the development of LED lamp, lamp etc. application demonstration and promotion of indoor lighting products and systems.

Timely access to the field of home lighting.

In the field of outdoor lighting, focusing on the development and application of LED tunnel lights, street lamps and other products and systems.

In the construction of No. [2012]72 "" 12th Five-Year "building energy planning" is mentioned, and actively implement the green lighting project demonstration, to encourage the local use of renewable energy such as solar and wind energy to provide lighting for city public areas of electricity, solar photovoltaic, expand scenery complementary scale lighting applications.

Comply with the requirements of the three ministries and commissions of the State Council in 2012 last year organized a semiconductor lighting products to promote financial subsidies project bidding. Standards for the development of the industry requires not only the market's desire, but also in the product has a standard specification.

At present, "architectural lighting design standards" B50034, "semiconductor lighting application of energy-saving evaluation technical requirements (2012 Edition)" has been completed, "LED indoor lighting applications technical requirements", "LED road lighting application technical requirements" has started preparing, and the new version of the "standard" architectural lighting design B50034 add LED product application in the indoor technology, including the selection of color difference between the same source should be lower than 5SDCM; room or place long-term work or stay, not to the temperature above 4000K; chromaticity coordinates and initial LED value in the life period of the deviation in CIE1976 chromaticity diagram, should not exceed 0.

007; LED lamp chromaticity coordinates in more than 10% of the peak intensity in different regions within the direction of the expected weighted product than the mean deviation in the CIE1976 diagram, should not exceed 0.004.

The performance index of LED lighting has a good prospect in indoor lighting applications, which is a prerequisite to comply with the relevant performance indicators in LED lighting products, LED application and indoor should meet the following conditions: the color index of not less than 80; less glare (to ensure that meet the requirements of glare must limit the surface brightness of the lamp); the temperature is not too high (standard the provisions of color temperature not higher than 4000K); to limit the color tolerance (standard color tolerance should be lower than 5SDCM), such as the United States DOE solid state lighting manufacturing research and development of new roadmap requirements by 2015 from 7SDCM to 4SDCM.

The best use of light, low light, Gao Guangtong, uniform light source.

Of course, the most important thing is to ensure a stable, consistent and acceptable performance.

LED lighting enterprises should seize the opportunity, we need to know that innovation is fundamental to the development of LED lighting, imitation of traditional lighting products can not play the advantages of LED.

Good and stable performance to meet the needs of lighting, and meet the needs of the user acceptance of a reasonable price.

Open up the LED interior lighting product development ideas, seize product innovation, design innovation, to avoid blind imitation, quick success and instant benefit, in order to promote the healthy development of the industry.
