LED lighting Outlook: price and efficiency trend? What is the problem?

Concern LED lighting in the future will be how to develop? In October 28, 2009, and is held in the Pacific Yokohama Exhibition Center "Green Device 2009" exhibition and seminar "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.

The first stage of the 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. Under the warning that the current regulations and standards related to LED is 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 to pay attention to. This is because there is no alternative fluorescent lamp for fluorescent tube type LED lamp standards, manufacturers in terms of brightness, power consumption, light and other standards and performance differences. In his speech, the performance of current under fluorescent lamp type LED lamp, the U.S. Department of energy disclosed below the fluorescent lamp, not as a substitute for the report, and on some industrial lighting products in Japan known as low input power products of fluorescent lamp, lamp brightness is lower than some more than 500g are instruments of the hidden danger of falling off report. 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.

In addition, the following also lists the consumers in the procurement of so-called fluorescent lamp energy saving LED lighting should pay attention to the problem. That is to confirm the purchase of fluorescent lamps is the latest Hf, or the original copper and iron ballast. At present, the overall efficiency of lighting appliances, Hf is about 100lm/W, copper and iron ballast for 60lm/W, the two big gap, LED lighting centered, 80lm/W.

The efficiency of white LED increased significantly from 1 to 2 years

Then the stage is Matsushita Electric lighting business department of the LED component development center of the Ministry of foufe Lee grew up. Lee said that the use of LED lighting white LED luminous efficiency is very obvious, the recent 1 ~ 2 years of progress is particularly significant. Although the value is close to 100lm/W, but still not exceed Hf fluorescent lamps on LED lighting appliances. 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%.

Luminous efficiency will continue to improve in the future, 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 efficient 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.

Benefits also talked about the prospects for organic EL lighting. Organic EL lighting has the advantages of light source, suitable for the main lighting such as dome light. There is a complementary relationship with the point light source LED. Although the development of more than LED 3 to 5 years later (big profit), but the big profit forecast, by 2020 to 2015, the efficiency of organic EL lighting will be equal to or higher than the Hf fluorescent lamp. If the cost is not higher than LED, then the opportunity for organic EL as the main lighting will be equal to or even more than LED. Thus speculated that the benefits, LED lighting will be the first application of the main lighting, but with the development of organic EL lighting, from around 2020, the use of organic EL lighting will gradually increase.

The company also issued a forecast on the potential of lighting power reduction technology before and after 2020. If the current Japanese lighting power consumption as 100, then all of the most efficient use of the current lighting appliances can reduce power consumption to 70. By 2020, with the expansion of more efficient LED lighting and organic EL lighting applications, as well as lighting configuration optimization and implementation of light control, power consumption is also expected to be reduced to 50.

What is the recommended retail price for LED lighting appliances in 2015?

The last stage is Toshiba lighting technology LED Department LED planning minister Misaki Sato Koji. Misaki Sato introduced the company's LED lighting appliance price forecasts and its October 2009 listing of the industry's highest efficiency known as LED bulbs.

Misaki Sato said, LED lighting published in June 2009 the unit brightness suggested retail price of 20 yen, about /lm, about 4 times for the use of Hf type fluorescent lamp lighting apparatus, 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 Hf type fluorescent lamp. By then, consumers will increase the willingness to use LED lighting. But even so, the price of Hf fluorescent lighting appliances is still lower than LED lighting appliances, therefore, Hf type fluorescent lamp appliances will not disappear from the market.

About LED bulbs, Misaki Sato said, 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 LED lights
