光技研 Company Profile

The large surface-emitting module provides a gentle light with rich color reproduction, even though it uses LEDs.

Kougiken Co., Ltd. is engaged in the development, manufacturing, and sales of special large-area light-emitting modules for high-power LED lighting. Conventional high-power LED lighting mostly consists of point light beams, which inevitably create areas of glare. To address these issues, we have focused on developing large-area light-emitting sources and have spent many years working on achieving a Ra (color rendering index: color reproduction) of 92 or higher, which is considered difficult for LEDs. By successfully developing a special light-emitting agent that includes special diffusion agents and light-emitting particles, we have succeeded in creating a large-area light-emitting module. Additionally, we have completed the development of a special module that controls blue light from LEDs to the greatest extent possible, ensuring that our products also address the blue light issue. Moving forward, we will continue to prioritize the improvement of Ra (color rendering) and consistently challenge ourselves with cutting-edge technology development.
