Received the "Lighting Promotion Award" from the Illuminating Engineering Society for Seiwa Electric's DC-powered tunnel LED lighting system.

Technologies registered in the New Technology Information System (NETIS) have adopted both the direct current power supply method (CG-170008) and (TH-15008).

The newly developed tunnel LED lighting system, the first of its kind in Japan, has achieved miniaturization and weight reduction of the fixtures by installing the power supply unit inside the electrical room and supplying power to the lighting fixtures in the tunnel with direct current. Conventional products had the power supply unit within the fixture itself, but this product does not have a power supply unit inside the fixture, allowing for miniaturization and significantly reducing installation work. Additionally, by consolidating the power supply unit in the electrical room, maintenance has been simplified. The direct current-powered tunnel LED lighting system reduces construction costs by making the lighting fixtures ultra-compact and lightweight and using a connector system for power wiring, while installing the power supply unit in the electrical room enhances maintenance ease and safety. The direct current-powered tunnel LED lighting incorporates technologies registered with the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System (NETIS) (CG-170008) and the technology for compact and lightweight LED tunnel lighting fixtures (TH-150008). Recently, we have supplied the tunnel LED lighting system for the Kyuuzan Tunnel (downhill L=1,704m) on National Route 185, under the jurisdiction of the Hiroshima National Highway Office, Chugoku Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism.

We have delivered sign lighting using tunnel lighting fixtures, the first of their kind in Japan, to the Shin-Meishin Expressway (from Takatsuki JCT/IC to Kobe JCT).

Sign lighting refers to tunnel lighting that shines white. In the event of a vehicle fire, it flashes red, and in the case of accidents, falling objects, or breakdowns, it flashes yellow to alert drivers. This allows drivers to drive their vehicles with peace of mind.

We have delivered pace maker lights using tunnel lighting fixtures, the first of their kind in Japan, to the Shin-Meishin Expressway (from Takatsuki JCT/IC to Kobe JCT).

The Pace Maker Light is a tunnel lighting system that shines white and has green lights that illuminate in the direction of travel, creating a flow of light that drivers instinctively try to catch up with, helping to restore speed and alleviate traffic congestion. Conversely, when drivers exceed the green light, the Pace Maker Light employs technology to assist in speed regulation.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
