LED tunnel lighting (aluminum housing) for the Ministry of Land, Infrastructure, Transport and Tourism and local governments.
Compact and lightweight LED tunnel lighting fixtures with excellent workability and safety. Achieves higher uniformity compared to our conventional products, featuring a uniform and low-variation light distribution design.

○ Long Lifespan The lifespan ensures 90,000 hours for both basic and entrance lighting. Basic lighting is maintenance-free for over 10 years with 24-hour operation per day (24 hours × 365 days × 10 years = 87,600 hours ≤ 90,000 hours). Entrance lighting is maintenance-free for over 20 years with 12-hour operation per day (12 hours × 365 days × 20 years = 87,600 hours ≤ 90,000 hours). ○ Lightweight and Compact, Improved Installability ● The body uses aluminum alloy, achieving industry-leading lightweight and compact design. It excels in installability and safety. ● The smaller size allows for installation in narrow cross-section tunnels that were previously difficult to install. ● The number of anchor bolts required has been reduced from four to two (the fixture can be mounted using two points on either side of the center of the mounting hole). Safety Measures ● The front cover is secured with a hinge-less latch structure, reducing corrosive materials and minimizing the risk of the front cover falling due to aging deterioration. ● A drop prevention structure is adopted for safety measures.

It excels in installability and safety. ● The compact design allows for installation with ample space against outer lines and architectural limits. ● The number of anchor bolts required has been reduced from four to two (the fixture can be mounted using two points on either side of the central mounting hole). Safety Measures ● The front cover is secured with a hinge-less latch structure, reducing corrosive materials and minimizing the risk of the front cover falling due to aging deterioration. ● As a double safety measure (to prevent falling due to corrosion of the lighting fixture), support metal is provided at the left and right positions on the top surface of the lighting fixture to implement fall prevention safety measures.
