Sharp high power white LED wavelength range is close to natural color


Among the high-power white LEDs for lighting released on June 26, 2007, the products with higher color derivation "GW5BNC15L00" and "GW5BNC15L10" use green and red fluorescent materials. The reporter learned at the company's technical briefing in Tokyo that both green and red fluorescent materials have a wide range of wavelengths. The average color derivability index (Ra) is around 80. While other companies have introduced products with Ra up to 90 or more, the company believes that products with a wide wavelength range are closer to natural colors.
"GW5BNC15L00" is a product with a color temperature of 5000K, and "GW5BNC15L10" is a product with a color temperature of 6500K. In addition, the ordinary white LED product "GW5BWC15L00" uses a yellow fluorescent material, and the incandescent light color "GW5DWC15L00" uses yellow and red fluorescent materials.
