Japan's interior LED lighting is promising

At present, American households have twice the power consumption of Japanese households and four times as many instruments and meters. Japan has become the country with the lowest energy use/GDP value in the world. However, Japan is not satisfied with this view. Japan will be low-cost in the future. It is arguable that there is no chance of winning the competition with many developing countries in the world. Therefore, the development of “environment”-related industries is the direction that Japanese entrepreneurs have agreed.

LED/OLED lighting looks promising
According to the plan of the Ministry of Economy, Industry and Technology of Japan, it is hoped that before 2030, LED/OLED bulbs will replace at least 60% of incandescent bulbs. Of course, the most important home lighting fluorescent lamp is still occupying the high luminous efficacy and economic advantages. The room for growth of fluorescent lamps has peaked, but the luminous efficiency of LEDs/OLEDs is still 20 times that of light output every 10 years, but the trajectory of cost decline is 90% every 10 years. It is estimated that this trend can be continuous at least. As of 2016, the luminous efficacy of LED/OLED lighting sources is expected to increase in the future (thereby making it more versatile and energy-efficient), and the price will drop to an appropriate level.

Japan and the United States, Europe and other LED light source manufacturers believe that at present, although the luminous efficiency of individual commercial LED lighting is only 80 lumens / watt, but in 3 or 4 years 120 ~ 150 lumens / watt high efficiency LED lights will be commercialized, then all products applied life. The total application cost of the cycle (light bulb usage plus electricity bill) will be lower than the LED light bulb. Manufacturers speculated that the future LED light to reach 200 ~ 300 lumens / watt will be able to reach the goal of around 2020.

According to the speculation of Japan's machinery industry association, by 2030, the coverage rate of LED/OLED lighting in Japan's interior lighting will reach 30%, accounting for 20% of the total amount of electricity used in lighting, and it will be possible to save energy and reduce carbon emissions. 18.7 billion kwh (kilowatt-hours) of annual electricity, or 7 million tons of carbon dioxide emissions.

OLED lighting will be LED lighting potential competition
LED lighting vision is promising, but can not overlook the development of another new generation of lighting technology, discrete components, that is, OLED lighting, OLED organic light-emitting diodes, is considered to be a new generation of display technology to connect tftlcd, but the more developed tftlcd Thin and light, more power, IGBT, and OLED difference is not relatively obvious, photosensitive resistance, so the use of OLED display products, or to establish profitable market as the highest criteria, after the profit model and market sturdiness, there are After profitability, it may naturally attract more companies to participate in and invest in such talents to accelerate the replacement of tftlcd opportunities.
