Tunnel lighting of Hoshi and Denki.

LED tunnel lighting (with initial luminous flux correction function) conforms to the LED road and tunnel lighting introduction guidelines (draft) and improves the fixture luminous flux.

The tunnel lighting from Hoshi and Denki adopts long-lasting, high-efficiency white LEDs as the light source, and by incorporating an initial luminous flux correction function, it achieves low maintenance and energy-saving capabilities. ○ It can reduce power consumption and CO2 emissions. ○ Maintenance work that involves traffic regulation can be minimized. Maintenance tasks that require traffic regulation, such as lamp replacement, can be reduced. 1. Long lifespan: 20 years; only one replacement of LED and control device; lifespan of 90,000 hours. The lifespan of the LED module is 90,000 hours, allowing for over 10 years of maintenance-free operation with 24-hour daily lighting. By coordinating the lifespan of the LED module and control device, only one replacement of both will be needed during the 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 accommodates 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: Two-stage dimming capability.

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.

This spring, we will be launching a new job site specifically for craftsmen and construction sites in the construction industry, called "CIC Craftsman Job." In advance of this release, we have prepared two special benefits exclusively for companies that pre-register. Benefit 1) You can advertise for free for three months from the release of the job site. Benefit 2) We will regularly send you information about job seekers (construction management engineers) via email. *You can unsubscribe if you do not wish to receive this. Companies facing challenges with labor shortages are encouraged to register during this opportunity.

Here is a case study of the production of a cross folding screen for Mr. F in the Kyushu area. This screen maintains the beauty of traditional folding screens while offering a custom feel with the freedom to choose surface materials. You can select from a wide variety of vinyl fabrics for both the front and back surfaces. It can be freely styled to suit the interior of the space and its purpose, ranging from Japanese modern to contemporary settings. Equipped with a "true tailoring" structure, it features durable stainless steel fittings and undercut baseboards. Weighing approximately 24 kg, it is solidly constructed to elegantly divide spaces. It supports the creation of ideal environments, regardless of whether they are Japanese or Western styles. ■━━━━━━━━□ ┃ Case Overview ┃ □━━━━━━━━■ ■ Year of Production: 2025 ■ Delivery Location: Kyushu Area ■ Materials: Vinyl fabric Colored mulberry edge True tailoring specification Undercut baseboard Stainless steel cover fittings

The seismic sensor device "HK-2" detects strong tremors equivalent to a seismic intensity of 5 or higher, transmits a signal to the control room, and emergency stops the facility equipment. 【Installation Location】 Automotive parts factory 【Challenges】 Due to the maintenance and replacement of the factory equipment control devices, we considered updating the existing seismic sensors as well, but since production had already ended, we were looking for alternatives. 【Effects After Installation】 The HK-2 has the function to emergency stop equipment during an earthquake, and since its functionality is the same as the existing device, it was introduced as a replacement. Its compact size also allowed it to fit within the existing control panel being used. ★See more examples of the seismic sensor device "HK-2" https://www.hotron.co.jp/recommend/HK-2_lp.html#anchor_a04 ◎For more details, please download the materials or contact us.

An article about our resident business has been published in the Daily Timber News (Housing Edition). In light of the enforcement of last year's amendments to the Energy Conservation Law for Buildings and the Building Standards Act, as well as the heightened interest in earthquake countermeasures for the Nankai Trough, the "wallstat verification," which is effective for visualizing seismic performance in line with current conditions, is introduced. Our company supports housing businesses nationwide through our construction business support service "Ken-Sapo," including wallstat, so we hope you will take a look.

On October 22, 2025, we would like to announce that Yuta Tawaki, our company representative, spoke at the "PPP/PFI University (22nd Term) First Session," hosted by the Development Bank of Japan (hereinafter referred to as "DBJ"). At this event, we introduced specific initiatives utilizing our physical and cognitive function visualization system "AYUMI Scan" to address the challenges of labor shortages and safety management faced by local industries, as well as the potential for collaboration with local governments and businesses. We exchanged opinions with participants on the new value created through collaboration between local communities and startups. ■ Presentation Content In the first part, our representative Yuta Tawaki delivered a lecture on the theme "Workers in a Super-Aging Society Protected by AI: Safety Management Supporting Corporate Growth." The lecture focused on the senior generation, who are skilled employees supporting the workplace, and introduced initiatives to enhance safety management using physical and cognitive function data while balancing productivity improvement. Additionally, through a roundtable discussion with our partner companies, Skylark Holdings and Tokyu Community, we exchanged opinions on practical case studies and the effects of implementation in actual workplaces.
