Prospect of LED energy-saving lighting

It is estimated that Japan's LED lighting market will reach its peak by 2015, according to Ishida Kiyoshi, executive director and LED business minister of Japan's Alice Oyama company. The author is surprised by this because it means that the LED lighting market, which has been expected as a growth field, will begin to shrink soon next year. Although this is the first special case in Japan to introduce LED lighting, Japan seems to have been introducing LED lighting at an unimaginable speed. The memory prediction that evokes the Author 2 years ago was released at the press conference jointly held by Alice Oyama and Philips Electronics Japan on January 30, 2014. The two companies announced at the press conference that they have signed an agreement to cooperate in the sales of outdoor lighting and industrial lighting (Figure 1). On the cooperation Philips Lighting business department responsible for emerging market countries business of christophschell ( President of Philips Electronics Singapore lighting development market) Emphasis: We have a sense of crisis as the Japanese market is about to begin to shrink. However, we will seek growth by providing the value of lighting, not just supplying LED devices and bulbs. The word value evokes the memory of the Author 2 years ago. At that time, the author heard such a sentence in Frankfurt, Germany: light has the power to make people move. This sentence words from Philips lighting the company responsible for commercial lighting business of marcdejong ( At that time, he served as executive vice president of Philips Lighting and CEO of professional lighting solutions business group) The mouth is in the large-scale lighting and construction technology exhibition Light Building2012 ( FRANKFURT, Germany, April 15, 2012 ~ 20th)Said in an interview with the author. Jong particularly emphasizes that people's mood and behavior can be changed by changing the brightness and color of lighting. Four atmospheres can be created. In fact, Light Building2012 has proposed several intelligent lighting schemes that make full use of the power of Light to improve production efficiency and comfort. Although it was a bit outdated information 2 years ago, the author still wants to introduce Philips's display content at that time. Representative displays of high value-added lighting are conference rooms and restaurants (Figure 2). By changing the color and brightness of lighting, four atmospheres can be created. For example, if you want to concentrate on the discussion in a limited time, turn the lighting into a bright high color temperature and cold color system. On the contrary, if you want to discuss slowly in a harmonious atmosphere, turn the lighting into a slightly dark warm color. By changing the brightness and color of the lighting from hundreds of LED bulbs hanging down from the ceiling and the LED lighting panel on the wall, not only can the switch be switched, but also the brightness can be slightly adjusted. The full-length mirror equipped with dimming and color mixing functions for clothing stores is also a good example (Figure 3). By reproducing the color of the actual clothing, customers can buy more assured. We have prepared light for specific scenes such as evening parties, meetings in conference rooms, and sunny outdoors. In the field of outdoor lighting and industrial lighting, which will cooperate with Alice ouyama, Philips's street lamps that can adjust brightness according to traffic flow are eye-catching (Figure 4). Internet-based control technology has been adopted on street lamps that are promoting LED. The number of street lamps lit and the intensity of light can be controlled according to the traffic flow, time, activities and weather of the road through the central monitoring system. The sales volume of the lighting business of Philips in 2013 was 8. 4 billion euros, and the sales volume of the lighting business of Philips with the main axis of providing value was 8. 4 billion euros in 2013. The company has about 4. With 60 thousand employees, 5 of the sales are invested in research and development every year. Schell stressed that lighting will accelerate the transition from analog to digital in the future. We will carry out various research and development to promote the digital revolution of lighting. He also said that the cooperation with Alice ouyama is not limited to LED, but will also introduce organic EL lighting if necessary. Japan's lighting market will take the lead in changing. The challenge of leading lighting companies with sales of more than 8. 4 billion euros will become the touchstone for predicting the future trend of the lighting market.
