It’s reported that the residential development of more than 200 houses in Azabu no Oka, Japan will use only LED fixtures for all its outdoor lighting. That means the areas will be lit entirely by LEDs. The development is being built by Toyota Smile Life Inc and has been dubbed Toyota “LED Town.”

The LED lights being installed at the development, located in Miyoshicho, Aichi Prefecture, Japan, will illuminate public areas including streets, sidewalks and parks as well as private areas such as the gate, porch and walls of each house. A total of 204 houses will be built, and more than 20 have already been completed. Each of the houses has four to five LED exterior lamps that light the roads and pathways as well as exterior walls of each house. The LED street lamps are installed only at the intersections of main roads inside the subdivision. It will take four years to build all the houses.

When completed, Azabu no Oka will have a total of about 1,000 LED lights with each house having four or five lights. To create relaxing and warm atmosphere, all the LED lights in the area are white LEDs that emit light similar to that of light bulbs and have a color temperature of slightly less than 3,000K.

In addition, only LED lights with high luminance efficiency were used to illuminate only the minimum necessary areas. Furthermore, the irradiating areas of LEDs were widened so that people can see wider illuminated areas and feel more brightness than the actual value. Through these methods, power consumption was reduced by about 75% compared with normal light sources.

The LED fixtures are being supplied by Japan Outdoor Lighting Mfg Co Ltd. Each light incorporates white LED modules manufactured by Toyoda Gosei Co Ltd. About five types of LED modules were used to make the LED lights, according to the fixture maker.
