A plan to comfortably light one of Japan's prominently spacious new campuses / Fukuoka City, Fukuoka Prefecture
Kyushu University is a National University that was established with the incorporation in 1949 of the old Kyushu University, which was founded in 1911 as Japan's fourth Imperial University. Since 2005, Kyushu University has been proceeding with a gradual partial relocation to its Ito Campus, located on the naturally blessed Itoshima Peninsula and boasting the largest acreage of 2,700,000m². The relocation of 3 undergraduate schools, 11 postgraduate schools / academic centers / engineering institutions, and 4 affiliated facilities has now been completed, and the spacious campus with its full range of leading-edge facilities is broadly divided into three zones: the West Zone, Center Zone, and East Zone. The West Zone's baseball ground was established as a facility principally for the university's extracurricular activities (rubber-ball baseball practice and competitions), and comes fully equipped with night-time lighting equipment. The brightness has been set at the general level for rubber-ball baseball (300lux for the outfield, and 500lux for the infield), with power saving high-output 830W LEDioc FLOOD DUELL LED floodlights installed to create a bright and comfortable lighting environment for night-time games. Light-bleed into the neighboring residential areas has been taken into consideration, and sufficient countermeasures against light pollution have been put in place, including angle adjustment and the installation of louvers for the outfield. Separate vehicle and bicycle lanes and a pedestrian pathway have been established in the 1.2km of space between the south gate and the West Zone in an effort to improve safety. Custom-specification LEDioc AREA ALIVIO LED streetlights have been installed as the lighting fittings lighting this route.Test cultivation fields for the university's Faculty of Agriculture are on both sides of the route, so light-pollution countermeasures are in place that take this into account, including rear reflecting panels and adjusted angles for the fittings. The 88 units of the custom-specification lights have been arranged in a staggered formation. They are dimmed to 50% during late-night periods and also shine with an original Kyushu University color as they safely light the roads with environmentally considerate light. Location appropriate lighting fittings have also been used for the area to the south of the Engineering Research Laboratory in the Engineering District, the parking areas, and passageways, with the installation of Kyushu University custom-made lighting equipment as streetlights to light the area around the south side of the laboratory. Light with superior color rendering and having a general color rendering index of Ra95 has been used to create relaxing nighttime scenery. Similar custom-made LED parking-area lighting fixtures have been used for the parking-area lighting, while LEDioc CEILINGⅡLED ceiling lights have been have been arranged in the passages within the Engineering Research Laboratory (in the Engineering District) for a combination of reduced power consumption and a pleasant lighting environment. At Kyushu University, based on the Public Design Guidelines for new campus design, in addition to functional lighting including crime-prevention and safety for the light environment, concepts include the establishment of image through lighting providing effects that are "newsworthy" an"landmark-esque," as well as consideration to avoid artificial light-bleed into surrounding areas in order to protect the natural environment and plant ecosystems.
The baseball ground is used for rubber-ball baseball practice and competitions. Each of its lighting poles has 15 LEDioc FLOOD DUELL high-output LED floodlights, which are environmentally friendly and contribute to power and maintenance savings.
The streetlights installed along the road leading from the south gate to the West Zone are LEDioc AREA ALIVIO custom-specification LED streetlights that have also been painted in an original Kyushu University hue.
Separate vehicle and bicycle lanes and a pedestrian pathway have been established and contribute to fewer accidents. They are safely lit by LEDioc AREA ALIVIO custom-specification LED streetlights that can be dimmed by 50% .
The main pedestrian walkway from the main entrance to the West Zone to the buildings at night. The pathway is lit using Kyushu University custom-made lighting equipment, creating an effect of rich night-time scenery.
The area around the Engineering Research Laboratory (Engineering District) at night. A pleasant lighting environment has been created with light with excellent color rendering that comes from Kyushu University custom-made lighting equipment.
The Engineering Research Laboratory (Engineering District) parking area is lit using Kyushu University custom-made LED lighting equipment, increasing safety at night.
The area around the Engineering Research Laboratory (Engineering District) during the day. The lighting fixtures are Kyushu University custommade lighting equipment compliant with high colorrendering (Ra95) CERALUX lamps.
The light lighting the passages inside the Engineering Research Laboratory (Engineering District) comes from LEDioc CEILINGⅡ LED ceiling lights, which contribute to maintenance savings with a long operating life of 60000 hours.
