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.

YUJI LED PHOSPHOR SELECTIONS



YAG LED Phosphors
Yttrium Aluminum Garnet LED phosphors are high efficiency phosphors suitable for coating LEDs with high CCT. Absorption peaks at 450 nm, and dominant emission wavelengths range from 540 - 560 nm.
LuAG LED Phosphors
Lutetium Aluminum Garnet LED phosphors offer comparable performance to YAG phosphors. We offer LuAG phosphors with dominant emission wavelengths ranging from 520 - 540 nm. Often used in conjunction with red phosphors for high CRI full spectrum coverage.
Nitride LED Phosphors
Nitride LED phosphors are crucial for high CRI and low CCT white LEDs. Dominant emission wavelengths range from 615 nm - 660 nm. They can also be applied in grow light LEDs where wide & stable red spectrum coverage is required.
Oxynitride LED Phosphors
LED Oxynitride phosphors can be used to package high CRI LEDs which require full spectrum coverage. Dominant emission wavelengths range from 500 nm to 650 nm.
