The annual global display exhibition FINETECH JAPAN 2009 and the first LED/OLED next-generation lighting exhibition have been successfully held at the Tokyo Ariake International Exhibition Center in Japan recently. The next-generation lighting technology has received a lot of attention from visitors, as it was last year. The 1000-person lecture hall was packed, including the number of people attending the lighting seminar, and the crowds on the exhibition floor were also in full swing.
Next generation forum topics
The first next-generation lighting forum invites global leaders such as Panasonic Electric Works, OSRAM, General Electric Company and Philips Lighting to talk about the world strategy for next-generation lighting, including Panasonic. The electrician's next-generation lighting business strategy, OSRAM's talk about the future of solid-state lighting (SSL) and the future of lighting, the third revolution in the lighting industry, and the next-generation lighting to open up a new future are now comprehensively described below.
What are the motives and reasons for developing the next generation of lighting product technology?
Matsuyoshi Katsuhisa, Minister of the Panasonic Electrician Lighting Business, talked about the importance of developing next-generation lighting products technology from the environmental perspective. According to the signing of the Kyoto Protocol issued in 1997, Japan’s greenhouse gas emissions must be reduced by 6% compared to 1990 before 2012, but in fact these years are still higher than 1990 emissions. To reach the Kyoto Protocol, Japan must cut 12.2% (about 156 million tons) of CO2 emissions by 2012. The data show that the CO2 emissions generated by businesses and households have increased the most in recent years, with an increase of 42% and 30% respectively compared with 90 years, indicating a significant improvement in commercial and household electricity. In the lighting business and household electricity, lighting accounts for a considerable proportion. In 2005, Japan’s lighting power consumption was 135.5 billion kWh/year, accounting for 15% of all electricity consumption. The CO2 emissions generated were 52.85 million tons, accounting for the total CO2 emissions in Japan (1.36 billion tons). 4%. Therefore, if the lighting equipment can be greatly improved, it will be quite helpful to reduce CO2 emissions.
In addition, LEDs have many advantages, so they are deep in residential electronics and public facilities such as mobile phones, notebook computers, LCD TVs, or in the automotive industry. With application potential, this will drive another wave of industry development and will also help the global economy. According to a survey by Yano Economic Research Institute, the global white LED market in 2008 was 40.2 billion yen. In 2013, five years later, the scale is expected to reach 413 billion yen, an increase of more than 10 times. The scale after 2018 It is expected to reach 708 billion yen.
At present, the difficulty of LED lighting is there? How to break through?
The biggest problem LEDs are currently experiencing is the high price and reliability of high-power products. On the price issue, Matsushita Electrician Song Yinbang Zhang pointed out that the price of 40W incandescent lamp is about 0.2-0.3 yen/lumen, while the fluorescent lamp is 1~20.2-0.3 yen/lumen, and the white LED falls at 4~10 yen/lumen. It is expected that the price of LEDs in 2012 will be close to fluorescent lamps, as shown in Figure 1.

It is the only rule to improve LED luminous efficiency and longevity (to do thermal management design and improve reliability). In addition to the improvement of the luminous efficiency of the chip, the LED also needs to reduce the efficiency of the lamp after the lamp is reduced. At present, the luminous efficiency is reduced by 30-50% from the chip to the final lighting module. In addition, through government policy promotion, LED will enter the lighting market more smoothly. Mr. Felder, President and CEO of OSRAM Opto Semiconductors Asia, will give a few examples, including (1) the Korean government in the LED lighting 1530 program, which will be in 2015. Let LED Lamp account for 30% of the country's lighting market; (2) Japan's Kyoto Protocol's goal for LED lighting is to replace LEDs with 8.8% fluorescent lamps and 13.7% of incandescent bulbs by 2010, thus reducing 3.4 million tons. CO2 emissions; (3) The Irish and Australian governments announced that they would ban the sale of incandescent bulbs in 2009 and 2010 respectively; (4) The Chinese government has funded more than $17 million in solid-state lighting projects since 2000.
