The next generation of lighting technology show: where is LED/OLED going?

Once a year the global display exhibition FINETECH JAPAN 2009 and the next generation of LED/OLED lighting exhibition has recently in Japan Tokyo Ming International Exhibition Center held successfully, the next generation of lighting technology by the visitors attention, as with the case last year, for 1000 people in the hall to participate in the seminar includes a number of All seats are occupied., lighting is also very enthusiastic the exhibition, and the crowd in a continuous line.

Next generation forum topics

The first forum invited the next generation of lighting issues to Matsushita (Panasonic ELectric Works), OSRAM (OSRAM), General Electric (General Electric Company) and PHILPS lighting (Philips Lighting) and other global leader, about the next generation of lighting world strategy, including Matsushita "next generation lighting" business strategy, OSRAM about the future of lighting solid-state lighting (SSL) third revolution trend and prospect, lighting industry, and open up new future for the next generation of lighting and other issues, the comprehensive explanation is as follows.

What are the benefits and reasons for the development of the next generation of lighting products?

Japan's Matsushita Electric lighting industry minister Matsu Kunishiaki from the environmental aspects of the importance of developing the next generation of lighting technology. According to the Kyoto Protocol, which was issued in 1997, Japan's greenhouse gas emissions must be reduced by 6% in 2012 compared with a year earlier in the year of 1990, but in fact it is still higher than in the past few years by the year of 1990. To meet the Kyoto Protocol, Japan must cut 12.2% (about $1.56) of CO2 emissions by 2012. The data show that in recent years, commercial and household emissions generated by the highest CO2, compared with 90 years, respectively, an increase of 42% and 30%, indicating a substantial improvement in commercial and household electricity space. Lighting business and household electricity, lighting accounted for a considerable proportion. In 2005, the total cost of lighting power consumption in Japan was 135 billion 500 million kWh/ years, accounting for about of the total electricity consumption. The CO2 emission was about 52 million 850 thousand tons, accounting for about CO2 of the total annual emissions of Japan (100 million tons) in. So if we can significantly improve the lighting equipment, to reduce emissions of CO2 is quite helpful.

In addition, because LED itself has many advantages, so in terms of the common consumer electronic products such as mobile phone, notebook computer, LCD TV (LCD TV), or in the automotive industry, potential deep residential and public facilities, this will lead to another wave of global industrial development the economy will also help. According to the survey report of Yano economic research, in 2008 the global white LED market size for 40 billion 200 million yen, in 2013 after 5 years, is expected to scale up to 413 billion yen, an increase of more than 10 times; but after 2018 the scale is expected to reach 708 billion yen.

At present, the difficulty of LED lighting in there? How to break through?

LED is currently experiencing the biggest problem is the price is too high, and the reliability of high power products. On the price issue, Matsushita Shoin Akira state minister pointed out that the price of about 0.2-0.3 40W incandescent lamp and fluorescent lamp lumens / yen, the yen / 1~20.2-0.3 in lumens, white LED in the 4~10 yen / LM, is expected in 2012 LED price can be close to the fluorescent lamp, as shown in figure 1.

Enhance LED luminous efficiency and life (good thermal management design and enhance reliability) is the best rule. LED in addition to the chip (Chip) to improve the luminous efficiency, but also to reduce the efficiency of the lamp made to reduce the current from the chip to the final lighting module, luminous efficiency will be reduced by 30-50%. Also through the promotion of government policy will make LED more smoothly into the lighting market, OSRAM Opto Semiconductors Asia president and Mr. Felder CEO cite a few examples, including (1) the South Korean government in the "LED lighting 1530" program, will allow LED to Lamp in 2015 accounted for 30% of the lighting market in the country; (2) Japan Kyoto targets of LED lighting to replace the fluorescent lamp is 8.8% and 13.7% in 2010 before the LED incandescent bulb, so as to reduce the CO2 emissions of 3 million 400 thousand tons; (3) Ireland and Australia government declared a ban on incandescent light bulbs respectively in 2009 and 2010 sales territory; (4) China government since 2000 has funded more than $17 million in the solid state lighting plan.

(3) LED lighting market compared to other lighting opportunities and its application in the future?

OSRAM Felder pointed out that in recent years the LED significantly enhance the luminous efficiency, the LED has been compared in the market to enter the Market Entry and Transition to Volume conversion to the production process, OLED is still under development and R & D Market Entry, while the traditional light source in the Volume "With" Business stage). As shown in Figure 2, LED is in the high slope of the S curve, indicating that there will be a high growth opportunities in the future. In contrast, OLED also need to overcome some technical bottlenecks, in order to look forward to good development.

In LED lighting applications market, OSRAM pointed out 6 major application areas, as shown in Figure 3, including (1) building lighting, building lighting (such as Building facades (Wall wash), wall lighting, wall lamp), light (Flood lights), the slot (Cove lighting) lighting and landscape lighting (Landscape); (2) billboard (Channel letters), Channel letters, such as advertising (contour lighting), contour lighting gas station; (3) portable consumer market (Consumer portable) (Flashlights), such as a flashlight, headlight lamp (Headlights), (Bicycle Light); (4) retail display (Retail Display), such as Display case lighting, General merchandize lighting department store
