How to achieve energy-saving lighting in Japan

Japan's environmental Province in order to popularize low-power lighting, identified 12 energy-saving lighting model business". These 12 businesses in the retail center as the center of the energy saving lighting program for the design of energy-efficient lighting to grant assistance, and announced the implementation of the method and practical results. This will be able to explore the introduction of energy-saving lighting enterprises prompted reference data to promote the popularity of energy-saving lighting.

This practice for the first time in Japan, the candidates for energy-saving lighting what kind of expectations? What are the problems of energy saving lighting? Funded by the government of 12 companies, Nakajima Ichiro ran the cafe and bar of Pronto company on behalf of the executive directors Takemura Norihiko and engaged in residential construction Sumitomo forestry residential business headquarters, commodity development minister accepted the reporter's interview with the station. As we all know, the food industry has been the implementation of a variety of shops in the operation of the cost reduction measures. Lighting measures?

Takemura: because we use the day for the cafe, the bar for the evening business model, so according to different periods of lighting. Bar hours, by weakening the lighting to create an atmosphere, but also reduce the power consumption. Specific practices for the use of indirect lighting with a spotlight on the table of food, create atmosphere.

The energy-saving lighting using 50W halogen lamp as a spotlight, indirect lighting is the use of LED lighting. As a result, the power consumption is reduced by about 40% when compared to the maximum output power.

Not only is the direct reduction of lighting electricity consumption, but also by improving the efficiency of air conditioning to reduce the cost of air conditioning in summer. Due to the weakening of the convection caused by the heat dissipation, the operation rate of the air conditioner and the exhaust fan can be reduced.

The new store will be opened in the future will introduce the concept of energy-saving lighting. - the design of energy-efficient lighting, which problems have surfaced? Takemura: through this improvement, found that there were a lot of waste in lighting. The original shop lighting to create an atmosphere to set up too many lamps. The full consideration of the role of each lamp, according to the purpose of reducing the number of lights. - how do you get LED and halogen lights on? Takemura: LED high illumination but poor color rendering. As a result, it can be used as indirect illumination for illuminating walls. To properly represent the pillars of the material to create an atmosphere. Lighting equipment used by Japanese manufacturers, LED is used by Chinese manufacturers of products. The reason is that the Chinese manufacturer of LED light-emitting larger. Due to the Japanese manufacturer of LED light-emitting surface is small, there is a problem in the central light after the light scattering. The Chinese manufacturers of LED products are not inferior to the same intensity of halogen lamps. Power consumption decreased from 50W to 4W, to achieve a substantial reduction. Japanese manufacturers in the past 1 years to start the introduction of illumination can be adjusted LED. The product is worth looking forward to. - what is the need for universal energy-saving lighting? Takemura: designers are extremely important to the awareness of energy-saving lighting. Lighting manufacturers are difficult to achieve energy-saving lighting. Because they want to set up a large number of lighting equipment. The design and construction of large developers must be responsible for the design point of view from the perspective of energy-efficient lighting, so that even if there is no lighting and other lighting knowledge of users, but also to achieve energy-saving lighting. In short, like seismic design as to energy-saving lighting. The popularity of energy-saving lighting outside the food industry is easier than imagined. Japan is only about 25 ~ 50 famous designers. Most of them to design western restaurant, etc.. As long as the well-known designers take the lead in the use of energy-saving lighting, energy-saving lighting can quickly spread. The price of LED lighting appliances used in residential buildings is still high, the model business of Sumitomo forestry is in line with the model room. There are a lot of LED schemes in the approved model business, but why not use LED? In the business model: Nakajima's goal is the overall power consumption will be reduced by 3, with high efficiency fluorescent lamp, the lamp number reduction to about half the original, can reach the expected goal. Only at the entrance and reception using LED. Our main business is to achieve energy-efficient residential lighting, is for ordinary consumers. Also considered if the LED price is low, then the full use of LED, but the cost of LED is still high. Although LED can reduce power consumption by about 4 and has a long service life, but the price is also a fluorescent lamp 5 times. The current situation is that for the hall and other lighting appliances to replace the more difficult, the use of life of 10 ~ 20 LED is more effective. Easy to advertise its value. LED specifications, in the past, the lower the color of the product is now a high performance color products listed, we are also very concerned about. In 2015, the blueprint for the development of luminous efficiency over fluorescent lamps has also been made public. - at this stage of residential, how to do energy-efficient lighting is effective? In the host: according to the scenes of life changing lighting, both low power and comfort is very important. It is necessary to re recognize by scanning a chandelier (Ceiling Light) design of uniform illumination in every corner of the room "in a room.". For example, the basic lighting can be achieved through 3 lamps, each table lamp using the power of 15W fluorescent lamp. Because the use of indirect lighting to illuminate the wall can set off a bright. Now the Japanese room has the problem which the illumination is too bright. However, no matter how consumers say, "indoor
