The compact and lightweight LED tunnel lighting "STAR LED'S TUNNEL" has been registered in the NETIS (New Technology Information System).

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 13.8Kg → Approximately 57% weight reduction New type 6.0Kg 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, and since the lighting cover is integrated into the main body, it reduces the risk of cover detachment. Features ○ Adopts an aluminum alloy body, achieving lightweight and compact design ○ Reduces corrosion-prone components by adopting a hinge-less 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.

Dear Sir/Madam, I would like to express my congratulations on the continued prosperity of your company. Thank you very much for your exceptional support. We would like to inform you that our company will be closed for winter holidays during the following period. We apologize for any inconvenience this may cause and kindly ask for your understanding. 1. Winter Holiday Period From Thursday, December 28, 2023, to Thursday, January 4, 2024. 2. Business Operations After the Winter Holiday Period We will resume normal operations from Friday, January 5, 2024.

● 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. Please feel free to contact us for more information!

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

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 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 you require a detailed technical explanation, please contact us.
