  • LED
  •  

  • Nighttime view of Chuo-Dori, where LEDioc ROAD street lights provide a pleasant lighting environment.

  • Nighttime view to the front of Shiraoka Station, where the lighting installations have been updated to LED, contributing towards energy savings and reductions in CO₂ emissions.

  • LEDioc ROAD street lights provide both increased brightness and energy savings in the vicinity of Shiyakusho-Dori.

  • LEDioc AREA TOLICA-L pole lights and LEDioc APPROACH TOLICA-L approach lights provide a secure and pleasant lighting environment at night for the much loved Ikoi-no-mori Park.

  • Nighttime view of Fureai-no-mori Park, a family friendly site equipped with facilities including an all-purpose field, walking courses, and barbecue area, which can be found next to Shiraoka City Hall. Retaining and reusing the existing lighting columns, the installations have been updated with LEDioc ROAD street lights.

  • With its wide open areas, Takaiwa Park is appreciated by many; it now also enjoys a heightened air of security by night thanks to the introduction of LEDioc AREA TOLICA-L pole lights to update the park lighting, providing ample illuminance at ground level whilst restricting vertical light spillage.

  • Shibayamanuma is the second largest natural wetland area in Saitama Prefecture, and the pedestrian routes around it are illuminated by LEDioc AREA TOLICA-L luminaires, whose design blends smoothly with its environment.

  • Utilized across a variety of uses, the sports hall of Shiraoka East Elementary School enjoys highly uniform lighting under LEDioc HIGH-BAY Γ high bay luminaires.

  • The Shiraoka City Workers' Sports Center is facility widely used by people of the area, who are able to enjoy a variety of sports there including basketball, volleyball and table tennis. Updating the high bay luminaires to LEDioc HIGH-BAY Γ is delivering energy savings whilst maintaining illuminance levels.

  • Compact and lightweight LEDioc TUNNEL KAEN Series luminaires safely illuminate the Takaiwa Tunnel.

Location

Aiming to reduce the costs it incurs from the installation and maintenance of lighting infrastructure, whilst at the same time also contributing towards combatting global warming through reducing consumption and CO₂ emissions, the City of Shiraoka has entered into an ESCO agreement which in January 2023 saw the whole replacement with LED of 3300 units of lighting across security lighting, street lighting, park lighting, sports facility lighting and school sports hall lighting under its management. Iwasaki Electric Co., Ltd. has taken on the management and maintenance of the scheme under the terms of a ten year agreement.

The incorporation of smart lighting capabilities to cover the street and parks lighting has enabled ON/OFF switching remotely, dimming their output levels, and verifying their operational status, all via a central management system (CMS); using the CMS to continually optimize the lighting environment throughout its operation and maintenance, the scheme is able to make yet further contributions towards energy savings. It is forecast that through the implementation of this ESCO project, the City of Shiraoka can expect a 70% reduction in CO₂ emissions and 60% reduction in energy consumption, resulting in savings of around 170 million Yen.

* Energy Service Company (abbr. ESCO) is a scheme that implements projects to reduce energy costs, covering the costs of the renovation works from within the savings achieved.
