JLEDS modify the general lighting with white LED development blueprint, luminous efficiency in 2015 will reach 150lm/W

Japan LED lighting oadg (JLEDS) discloses a lighting apparatus with high power LED technology development blueprint, put forward respectively white ordinary products (high efficiency type), high color products and lighting color products (lamp color type) by the end of 2020 the luminous efficiency targets. According to the target, before and after 2015 luminous efficiency is expected to reach 150lm/W. In general, the luminous efficiency of high efficiency products in fluorescent lamp is about 100lm/W, the efficiency of white LED products in 2008 will reach about 100lm/W, high color type will be more than 80lm/W, the bulb color type will reach about 70lm/W. 2010 is expected to reach about 130lm/W, 120lm/W and above 90lm/W, in 2015 is expected to reach more than 160lm/W, 140lm/W and above 130lm/W.

JLEDS is to promote the popularity of LED lighting system in the domestic industry groups. The group in September 2005 has also released a white light LED technology development blueprint, the technical development blueprint for the revised version. JLEDS joined the company to carry out a questionnaire survey and statistics, and on this basis to develop the blueprint for the development of.

With regard to the popularity of LED lighting, the technology development blueprint, said the luminous efficiency of more than 100lm/W in 2010 around the commercial facilities as the center for universal. In the light (white light emitted from the LED light toning etc.) improved after 2015, LED lighting will be popularized in the office and residential areas. LED lighting is expected in Japan's domestic market size in 2010 will reach about 400 billion yen, in 2015 will reach about 800 billion yen.

The technology development program also addresses the challenges of promoting universal access. It is pointed out that the biggest subject of popularization is cost. The cost of LED lighting fixtures is 5 to 10 times that of fluorescent lamps and HID appliances. This is because the price of the unit brightness of the light source (yen /lm), the white LED to be higher than two digits, but also the need for heat sink, power and lenses, etc.. JLEDS believes that not only to reduce the cost of light source, reduce the cost of peripheral components is also very important. In addition, attaches great importance to indoor lighting color temperature and color rendering, so it is also necessary to improve the quality.
