Japan's full use of LED lighting new office building power consumption reduced by 40%

Otsuka LED lighting used in all the "Chamber of Commerce Chamber of Commerce Yokohama Otsuka building completed.

The chamber of Commerce Building for Yokohama Otsuka 8 on the ground floor, 1 floor attic, a total area of 8197m2, using a total of 6201 LED lighting apparatus. LED lighting into the chamber of Commerce headquarters for Otsuka volume 1919, the company responsible for the import of the hotel for 2486 (a total of 4 hotels), takashimadaira logistics center is 2563, compared with more than the amount of imports, import more attention. According to Otsuka estimation compared with the chamber of Commerce, the existing fluorescent lamp light source, the power consumption can be reduced by about 40%, the 790kW can save power every day. Otsuka chamber of Commerce said, in addition to the use of LED lighting appliance, high luminous efficiency, but also according to the specific use of the environment, to adjust the brightness of the light.

The chamber of Commerce Building Yokohama Otsuka LED lighting compared with lighting apparatus using existing light source, a large number of lighting equipment.

The ceiling lights in the office use Fawoo's LED lighting device "LumiDas-H" in the input power of 22W products (color temperature of 5300K). The lighting apparatus is not directly installed on the ceiling, but the first two square appliances in the configuration of 22W in 600mm * 600mm, and then in the whole apparatus is covered on the inhibition of LED glare on the cover layer.

At present, the degree of dimming can be selected from the pre-set options. However, according to Otsuka chamber of commerce can also enable the sensor linkage lighting control, for example, the use of automatic external light illumination sensor according to the brightness control, using sensor open only someone in the position of the lighting device etc.. The company will take this kind of sensor linkage lighting control as the next direction of development. In addition, the roof is equipped with light projector, where the use of LED lighting equipment. LED lighting products using Fawoo company's input power of 80W, compared with the use of halogen lamps, power consumption can be reduced to about 1/5.
