Approximately 57% weight reduction from our conventional LED tunnel lighting, miniaturizing the product to reduce labor in construction work and decrease load on civil structures.
NETIS (New Technology Information Provision System) Registration Number: TH-150008-A Comparison of Equipment Weight ○ Our LED tunnel lighting: Conventional type 13.8 Kg → Approximately 57% weight reduction: New type 6.0 Kg This leads to labor-saving in construction work and a reduction in load on civil engineering structures. Recommended not only for newly constructed tunnels but also for aging countermeasures in existing tunnels. Significantly improves safety, as the lighting cover is integrated into the main body, reducing the risk of cover detachment. Features ○ Adoption of aluminum alloy body for lightweight and compact design. ○ Reduction of corrosion-prone components by employing a hinge and latch-less structure. ○ Conducted the "Neutral Salt Spray Test" as per JIS Z 2371 and confirmed no rust occurrence (test duration: 1,500 hours). ○ Capable of supporting AC 265V and 415V/460V without a down transformer.

basic information
We have achieved a reduction in weight and size for LED tunnel lighting. Until now, the installation work for tunnel lighting has been challenging, but this product weighs approximately 6.0 kg, making it lightweight and allowing it to be lifted with one hand. This reduces labor in construction work and shortens installation time, leading to a reduction in installation project duration. Additionally, by reducing weight and size, we decrease the load on civil engineering structures. Once installed, the LED tunnel lighting is intended for long-term use. By choosing a lighter product, we contribute to reducing the load on civil engineering structures within the tunnel. The product lineup includes basic lighting types, basic lighting with pro-beam distribution types, and entrance lighting options. Adoption for newly constructed tunnels, including highways and general roads, as well as replacement of existing tunnel lighting, is also progressing. We hope you will consider it.

Company information
Hoshia Electric has established itself as a top manufacturer in various fields, including information display systems such as road information boards, industrial lighting known for its waterproof and explosion-proof features under the name "Water Pearl," tunnel lighting that began with the full-scale installation in the Kanmon Tunnel, and resin products represented by "Cutting Duct." As a new business, we started an electromagnetic noise countermeasure (EMC) product business in 1997 to address electromagnetic noise issues arising from digital devices. In the LED business, we successfully developed a blue light-emitting diode in April 2002 and a white light-emitting diode in December of the same year. Based on these technologies, we are actively expanding our business in the field of LED lighting fixtures, ranging from roads and tunnels to industrial lighting. On March 9, 2018, Hoshia Electric Co., Ltd. was listed on the Tokyo Stock Exchange First Section. In April 2022, we transitioned to the Tokyo Stock Exchange Standard Market. Moving forward, we will continue to leverage our creative thinking and technological capabilities cultivated thus far to develop even more innovative products and strive for business expansion.
