Taisei Denshi Seisakusho Co., Ltd.

Manufacturing of surface-emitting LED parts using semiconductor manufacturing technology

We apply semiconductor manufacturing technology to the manufacturing of surface-emitting LED parts. We mount LED bare chips directly to substrates, and develop and manufacture LED plates having a thickness of approximately 3 mm by wiring with gold wire without using solder. Our products are used in LED stands and building materials in which LEDs are embedded. We blend phosphors in house, which determine the LED emission colors, and so can handle various customizations (color temperatures). We provide LEDs for applications ranging from signs to high color-rendering LEDs for displaying products.

[Company strength]
We blend phosphors in house, which determine LED emission colors, and so can offer customization (color temperature) for customers, thereby providing LEDs for applications ranging from signs through high color-rendering LEDs for displaying products.

[Business description]

[Industry]
Manufacturing

[Strength of products/technologies]
The color rendering value of LEDs currently developed in our company is Ra96, but we aim to develop a true color LED with Ra100.

[Representative's message]
The LED market is currently saturated and suffering price competition, and it is difficult to differentiate similar products. Accordingly, we aim to help manufacturing products not existing in the market and value-added products.

[Company structure for market development/overseas expansion]
We try to manufacture innovative products not offered by other major manufacturers. We have acquired a domain name for our company, and recently launched a website to expand sales channels. We also would like to effectively use IT, including registering with J-GoodTech, and try to make our technology well known, leading to meetings with new customers.
