摘要

The wavelengths of dual-wavelength light-emitting diodes (LEDs) are near ultraviolet (UV) at approximately 409 and 459 nm for blue when driven at 20 mA. The near-UV emission intensity of LEDs is stronger than the blue emission intensity with a 20 mA driven current. The green and red emission intensities of the phosphor are almost the same as, but less than, the blue emission intensity of the dual-wavelength LED with a 20mA driven current. The CIE color coordinates are x = 0.32 and y = 0.35, while the dual-wavelength LED with a green and red phosphor LED lamp is driven at 20mA.
