ひかり屋根 List of Products and Services

"The Hikari Roof Atokara II" is a skylight designed to improve existing skylights that allow direct sunlight and ultraviolet rays to enter, worsening the working environment, and to be used as lighting. It diffuses only a portion of sunlight and directs it indoors, significantly reducing power consumption. Please feel free to contact us when you need assistance. 【Features】 ■ High light-blocking performance ■ Insulation performance (heat protection) ■ UV cut ■ High color rendering natural diffused light *For more details, please refer to the PDF materials or feel free to contact us.

Technology under patent application. PCT/JP2021/042371 (May 27, 2022) The installation work of equipment such as skylights and roof fans mounted on corrugated roofs requires workers to lean their heads into the opening from the roof and tighten nuts using tools directed from the bottom to the top. This type of work is quite difficult, leading to longer working hours and making it challenging to ensure safety. This product is designed so that a single worker can perform the installation work more safely, easily, and quickly, allowing them to use nut-tightening tools like wrenches from the top side of the roof. *For more details, please feel free to contact us using the inquiry information below.

• Reinforcement and repair materials

We would like to introduce an application example in the health field using "Hikari no Oasis®," which our company is currently developing and researching. Improvement of myopia issues in children through ICT electronic textbooks is realized in the "Hikari no Kyoshitsu" utilizing diffused light. High-intensity light therapy using diffused light eliminates power consumption. 【Classroom Illumination Examples】 ■ Minimum value: 300–750 lx ■ On sunny days, diffused light of 1,000–1,500 lx can be obtained for several hours. *For more details, please refer to the PDF document or feel free to contact us.

• Solar Goods Solar Lighting

The "Hikari no Oasis (R) Solar Sharing System" is a technology developed around 2011, inspired by various hints during its development. Perovskite and other materials are used in the solar panels. By utilizing diffuse light technology, it is possible to increase both crop yields and power generation. 【Features】 ■ Uses perovskite and other materials in solar panels ■ Utilizes diffuse light technology ■ Increases crop yields *For more details, please refer to the PDF materials or feel free to contact us.

• Solar System Solar Module

"Hikari Yane Tsunagu" is a hybrid lighting control system that combines natural light and artificial lighting. It predicts indoor illumination based on the output of solar panels and adjusts the lighting fixtures without the need for light sensors, maximizing the use of natural light (diffused light) from the sun. This significantly reduces the time that daytime lighting is on (and consequently, power consumption). 【Features】 ■ Maximizes the use of natural light (diffused light) from the sun ■ Significantly reduces power consumption ■ Achieves over 60% energy savings annually *For more details, please refer to the PDF materials or feel free to contact us.

• Photovoltaic power generation system (solar system, energy-saving housing, electricity sales business)

The "W470" is a safe and secure eco skylight (light-diffusing skylight). Considering the weaknesses of skylights, such as strong light ingress, damage during storms, and leakage issues, as well as improving workability, it can utilize sunlight as lighting. Please consult our company when you need assistance. 【Features】 ■ New leak prevention system ■ UV cut ■ High light-blocking performance ■ Insulation performance (heat countermeasures) ■ High color rendering natural diffused light *For more details, please refer to the PDF materials or feel free to contact us.
