Tunnel lighting LED basic lighting ceiling mount (CL) type
Tunnel Lighting LED Basic Lighting KWLED08010CL-SS-V2
LED tunnel lighting (with initial luminous flux correction function) has been improved to comply with the LED road and tunnel lighting introduction guidelines (draft) and enhance the fixture luminous flux.
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 lifespan of the LED module is 90,000 hours, allowing for maintenance-free operation for over 10 years with 24-hour daily use. The control device for the LED module is also designed to have a coordinated lifespan, resulting in only one replacement of the LED module and control device 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 feature made possible by LEDs, with two-step dimming capability. 4. Initial luminous flux correction function (our proprietary feature). 5. Standard equipped with luminous flux reduction alarm function (our proprietary 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 ambient light sensor is used for initial luminous flux correction. This corrects the initial excessive luminous flux while also compensating (suppressing) fluctuations in luminous flux at low temperatures, further enhancing energy savings. The initial luminous flux correction unit is equipped with an alarm lamp, which blinks (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 the LED module control device into a unit, labor-saving in replacement work is achieved. During replacement work, a disconnection switch for the main power supply is standardly equipped to allow work to be done without circuit power interruption.

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. Back to the roots of manufacturing "From the Kyoto to the world"
