Tunnel Lighting LED Basic Lighting Ceiling Mount (CL) Type
LED tunnel lighting (with initial luminous flux correction function) has been improved to comply with the LED road and tunnel lighting introduction guidelines (draft).
LED Tunnel Lighting By adopting long-life, high-efficiency white LEDs as the light source and incorporating an initial luminous flux correction function, we achieve low maintenance and energy-saving features. 1. Long Life: 20 years, with only one replacement of the LED and control device; lifespan of 90,000 hours. The LED module has a long lifespan of 90,000 hours, allowing for maintenance-free operation for over 10 years with continuous lighting of 24 hours a day. By coordinating the lifespan of the LED module and control device, only one replacement of both will be needed during 20 years of operation. 2. Lineup: Two types of light distribution and four types of light source capacities. With two types of light distribution and four types of light source capacities, it can accommodate a wide range of design speed conditions (40-80 km/h). ■ Ceiling-mounted wide span (CL) … two types: LED 50W, 80W ■ Side wall-mounted wide span (BL) … four types: LED 40W, 50W, 80W, 100W 3. Supports special dimming: A function made possible by LEDs; two-stage dimming is possible. 4. Initial luminous flux correction function (our unique feature). 5. Standard equipped with luminous flux reduction alarm function (our unique feature). 6. Modularization of component parts.
basic information
By adopting a 65% dimming capability, brightness can be reduced even under conditions where dimming was previously impossible, achieving energy savings. An illumination sensor is used for initial luminous flux correction. This not only corrects the initial excessive luminous flux but also suppresses fluctuations in luminous flux at low temperatures, further enhancing energy savings. The initial luminous flux correction unit is equipped with an alarm lamp, which flashes (using a red high-brightness LED) when the luminous flux (maintenance rate) of the LED module falls below 80%. The alarm function allows for easy identification of when the LED module needs to be replaced, improving maintainability and safety. By integrating the LED module and LED module control device into a unit, labor-saving in replacement work is achieved. A disconnection switch for turning off the main power supply is standard equipment, allowing work to be carried out without circuit power outages.

Lightweight, compact LED tunnel lighting from Seiwa Electric.
Lightweight and compact LED tunnel lighting from Seiwa Electric TALEDA Series NETIS (New Technology Information System) Registration Number TH-150008-A Comparison of Fixture Weight ○ Our LED tunnel lighting Conventional Type 13.8Kg → Approximately 57% weight reduction New Type 6.0Kg Installation work for tunnel lighting fixtures has been challenging until now, but this product is lightweight at approximately 6.0Kg, allowing it to be lifted with one hand. This reduces labor in construction work and shortens installation time, leading to a reduction in installation construction duration. Additionally, by being lightweight and compact, it reduces the load on civil engineering structures. Once installed, the LED tunnel lighting is intended for long-term use. By choosing a product that is even slightly lighter, we contribute to reducing the load on civil engineering structures within tunnels. The product lineup includes basic lighting type, basic lighting with pro-beam distribution type, and entrance lighting. Adoption for newly constructed tunnels, including highways and general roads, as well as replacement of existing tunnel lighting, is progressing. We hope you will consider it.
