LED lighting concern, the future development will be how?

LED lighting in the future will be how to develop? The day before, in Japan's "Green Device 2009 Forum, Matsushita Electric, Toshiba lighting technology lighting appliance manufacturers, the industry group LED lighting oadg (JLEDS) respectively. The expression of their views.

JLEDS operation planning committee chairman Shimode Sumio stressed that the current LED lighting and LED lighting to the strength of the gap, to promote the popularity of LED lighting must solve the problem in the premise of recognizing the gap between the. And warned that the current regulations and standards related to LED is still not perfect, there is a potential risk of quality safety products into the market. Among them, the replacement of the "household hanging fluorescent lamp appliances", "incandescent lamps and discharge lamps appliances" and other existing light source LED lighting equipment in particular need attention. This is because there is no alternative fluorescent lamp fluorescent tube type LED lamp standards, manufacturers in terms of brightness, power consumption, light distribution and other standards and performance differences. Under the expected, Japan will be in the next 2 to 3 years to complete the formulation of laws and regulations. Prior to the improvement of the regulations, JLEDS will urge companies to join the community to comply with social consensus and relevant laws and regulations.

White LED efficiency increased significantly Matsushita Electric lighting business department of the LED component development center of the Ministry of foufe said Lee grew up, the use of LED lighting white LED luminous efficiency is very obvious, from 1 to 2 years is particularly significant progress recently. Although the figure is close to 100lm/W, it is still beyond the Hf fluorescent lamp for LED lighting. Because of the use of white LED lighting assembly, a power supply circuit of the power conversion loss, temperature and input current caused by the decrease of luminous efficiency in appliances, optical loss under the influence of the efficiency of lighting the overall (comprehensive efficiency) about the luminous efficiency of white LED from 50 to 70%, even using the latest white LED can only reach about 80%. In the future, the luminous efficiency will continue to improve, Lee predicted that the overall efficiency of the Hf fluorescent lamp beyond the LED lighting appliances will be 2010 to 2015 years, "by then, LED will really become the efficiency of No.1 lighting". For the cost is still expensive, Lee said that the brightness of the white LED unit costs less than 1 yen /lm from 2011 to 2012, the price of LED lighting will be more moderate. A large number of white LED LCD panel backlight used in the formation of a strong source of cost reduction pressure will be the driving force of the decline in the cost of white LED.

On LED lighting the suggested retail price of Toshiba lighting technology LED LED planning minister Misaki Sato Koji introduced the company's LED lighting appliance price forecast and listed in October 2009 known as the industry's highest efficiency LED lighting. Misaki Sato said, LED lighting published in June 2009 the unit brightness suggested retail price of 20 yen, about /lm, about lighting apparatus using Hf type fluorescent lamp 4 times, the price gap is large, but after 2015, the price will be reduced to slightly higher than the Hf type fluorescent lamp level, comprehensive efficiency will reach 120 to 130lm/W, significantly exceeded the type Hf fluorescent lamp. By then, consumers will increase the willingness to use LED lighting. Even so, the price of the Hf fluorescent lamp is still lower than that of the LED lighting device, so the Hf type fluorescent lamp is not going to disappear from the market. Misaki Sato said that the efficiency of the LED bulb has been rapid development. Toshiba lighting technology published in 2006 when the LED bulbs, LED bulbs overall luminous efficiency of only 18lm/W, only to replace decorative bulbs. After that, the efficiency of LED lighting gradually increased to 45lm/W in 2007, 68lm/W in 2008, already can be used as lighting with light bulbs, 82lm/W in 2009 and 93lm/W in October is to replace the ordinary lamp bulb for lighting level. In addition, Misaki Sato also demonstrated the use of LED lighting electricity saving effect. If all of the existing lighting is replaced by LED lighting, lighting power consumption is expected to reduce by about half.
