J goodtech

The productization of high-intensity LED lightings that have a high color rendering , low power consumption and long life time.

We are involved in designing, developing, manufacturing, and selling LED lighting. Our Lightning J series high-intensity LED lighting can freely controll light wavelengths and color temperatures. Compared to HID lamps (mercury lamps, etc.), feature of these LED lighting are low power consumption , longer life time (60,000 hours), and high color rendering (Ra75 to Ra90). In 2012, our business was certified as a new industry cultivation project by the Japan Finance Corporation. We have also received awards from the Kyushu Bureau of Economy, Trade and Industry and from economic groups.

  • Business Outline

    We have done the LED lighting business (development / design, manufacturing, sales), consigned development/design business, consigned production business. For LED lighting, we develop / design, manufacture and sell a high intensity LED lighting. “Lightning J” series 80W-800W that possess large integrated single planar LED light-emitting source, color LED lighting, LED fishing light, sunlight controlling LED products.

  • Product Strength

    Using our unique heat-off technology (highly efficient heat diffusion and exhaustion structure), we have successfully developed large integrated single planar light-emitting LEDs in which light sources are concentrated at a single point. Previous issues such as "no light is reached","light does not spread","light is not even" were solved. By solving these problems, uniform light now extends widely and has a sufficient reach. Compared to HID lamps (mercury lamps, etc.), our lamp feature of these LED lighting are low power, longer life time (60,000 hours), and the world’s highest-level color rendering (Ra75 to Ra90).

  • Company Strength

    We can provide the high-intensity LED lighting products that have LED sources using our independently developed large integrated single planar light-emitting method. By incorporating the production processes of LED device manufacturers, we have established an integrated production system from LED light sources (modules) to compleated products. We have also developed the best mixture of phosphor and sealing conditions. We now have an advantage of manufacturing products with the ability to freely control the optical wavelength, color temperature, and average color-rendering index.

  • Company Structure

    Inquiries from large / foreign enterprises will be addressed by our business promotion/management team. Technical questions will be answered by our technical team and will visit client sites as required. Our CEO will lead management and we will address our clients faithfully.

Message from President
Satoshi Fujii

We have operated as a support group for development of electronic manufacturers. In 2009, we have put our long-accumulated knowledge of technology into action to start an large LED lighting business and have started selling from June 2011, when we had our LED output of 80W-480W products completed. Our large integrated single planar LED light-emitting source method has become known and sales are increasing yearly. We will continue to challenge technical development while maintain a stable production to produce high performing and high quality products to domestic and international markets.Through the LED lighting, so we will continue to provide products that benefit society.
