YUJI LED PHOSPHOR MATERIALS

WHITE LIGHT AS CHEMISTRY

Phosphors are a crucial material in the manufacture of white LEDs. Phosphor chemistry and composition largely determine an LED's efficiency, light quality and stability. At our subsidiary Nakamura Yuji, a joint venture with investment from Mitsubishi Chemical Corporation, we understand phosphor technology at a fundamental chemical level, allowing us to pursue the best chemical formulations and manufacturing processes that result in the highest quality possible.

HIGH BRIGHTNESS, HIGH STABILITY

Despite a seemingly ubiquitous LED market, high brightness and stability are difficult to come by, particularly for high CRI LED products. Our consistent focus on improving the brightness and stability of red nitride phosphors has allowed us to become an industry leader in providing high CRI LEDs at efficiency levels and stability in line with standard CRI level LEDs on the market.

VERTICAL INTEGRATION

Our ability to work across LED phosphor, packaging, PCB & assembly facilities allows us to work provide highly customized products that meet your exact needs. Typical projects range from custom spectrums or color points (white & non-white), CRI/CCT combinations and PCB/fixture integration.
