Analysis: Observation of LED lighting opportunities from LIGHTING JAPAN

FINETECHJAPAN display exhibition organized by the ReedExhibitionsJapan in April, 15~17 was in Tokyo in the Ming, together also held a new generation of lighting technology exhibition - LIGHTINGJAPAN (with first LED/OLEDLightingTechnologyExpo title), held in April 15th of a new generation of lighting keynote speech, attracted more than 1000 people in the audience, visible a new attraction the generation of lighting manufacturers, this event has over 4, 5 years ago the FPD exhibition or number of audience last year some important solar photovoltaic exhibition development, which is also representative of Japan and many overseas manufacturers much more emphasis on the market.

A new generation of lighting is a part of Japan's national development strategy

What exactly is the new generation of lighting? Is it so positive about its future trends and market opportunities? In fact, we can analyze the overall development of Japan's national strategy, you can know that can attract a lot of attention is not without reason.

Japan is already the amount of energy used throughout the world in countries with the lowest /GDP value, far below the emerging countries of India; the average consumption of American households was 2.4 times the Japanese family, but Japan is not satisfied with Japan in the future if the low cost of mass production and the development of Chinese field world competition, it is hopeless. So the development of the "environment" of related industries, is a Japanese entrepreneur consensus direction.

Time to stand on LED/OLED lighting

According to the Japanese Ministry of economy plan, hope before 2030, at least let LED/OLED bulb replacement incandescent bulbs of more than 60%, although the main home lighting - fluorescent lamp has high luminous efficiency and economic benefits of better advantages, but fluorescent technology growth has peaked, and the luminous efficiency of LED/OLED is still a continuation of every 10 years the output growth of 20 times, but the cost is reduced by 90% every 10 years the estimated trajectory, this trend at least until 2016, therefore, the luminous efficiency of LED/OLED lighting is expected to increase continuously in the future (the application will be more extensive and more power), and the price will be reduced to reasonable stage.

Japan and the United States, Europe and other LED light source manufacturers believe that the current general commercial LED lighting luminous efficiency is 80 LM / W, but high efficiency LED lamp 3, 120~150 lumens / watt within 4 years will be commercialized, then the entire product life cycle total cost (cost plus fee electric bulb), will be below the LED lamp bulbs (CompactFluorescentlamp; CFL). Manufacturers predict the future of LED lights to reach 200~300 lumens / watt will be around 2020 to reach the target.

According to the Japan Federation of machinery industry forecast, 2030, LED/OLED lighting rate will reach 30% in the popularity of Japanese indoor lighting, electricity accounted for 20% of the total lighting, in energy saving and carbon reduction benefits, will save 18 billion 700 million kWh (kilowatt hours) the power of the year, or 7 million tons of carbon dioxide emissions.

OLED lighting will be a potential competitive technology for LED lighting

Optimistic about the development prospects of LED lighting, but can not be ignored a new generation of lighting technology, that is OLED lighting, OLED organic light emitting diode, is regarded as a new generation of display technology, continuous TFTLCD TFTLCD but more development more light, more power, and OLED is not absolute difference significantly. The application of OLED in display products, or to establish early market profit as the supreme principle, the profit model and market consolidation, profit of nature can attract more enterprises to participate in the investment, so as to accelerate alternative opportunities for TFTLCD.

OLED is a surface light source, so the effect will be more lighting point light source LED in visual effect is more comfortable, OLED is more thin, should be a new generation of lighting technology is superior, but the development of OLED lighting late, the luminous efficiency of the backward LED about 3 years or so, the cost should be reduced to LED with the same level. According to the forecast by the U.S. Department of energy in 2008, low-end products until about 2018~2020 years, high-end products may be more, so the future of a new generation of lighting can be divided into two levels, one is the high-end OLED lighting market, the other is widely used in LED lighting market street and general applications.

OSRAM and other manufacturers also develop OLED lighting

In the current LIGHTINGJAPAN, OSRAM (OSRAM) said OLED lighting efficiency can reach 100 lumens per watt in 2012, and LED lighting of the 130 lumens / watt gap is limited. However, there are still practical problems to be solved. Such as the current OLED lighting in the commercialization of the lamp, luminous efficiency is also more than the laboratory data in half, this is the future of commercialization to be overcome.

Japanese manufacturers in the exhibition Lumiotec ultra-thin OLED light source, attracting the attention of many people, but the observation of the exhibition situation, in general, this is still the majority of the LED lighting fair. South Korea's KMW company is also a dragonfly shaped LED street lamps as the theme of the exhibition, the street lamp with a small crime prevention device and mobile communication antenna, the Seoul municipal government consider. In addition, the Japanese Mitsubishi LED light source can be displayed as the traditional incandescent lamp as 360 degree radiation LED lamp, the product has been commercialized, the estimated annual is about 1500 yen, incandescent electricity, and the service life is 20 times of incandescent lamp is about 40 thousand hours.

In 2008 the world lighting market size has exceeded $110 billion, accounting for about 7 of lamps, lighting accounted for 3, while the market is in each region each regional companies dominate the market, unlike the IT products are all situations, but in the past 1 years is still attracting a large number of parts manufacturers invest,
