Abstract
An LED luminaire cover light diffuser and a use thereof are provided. The LED luminaire cover light diffuser is used for an illumination cover of an LED luminaire that illuminates a target object to enable the target object to be seen. The LED luminaire cover light diffuser includes base resin; light diffusing agent; and a coloring matter that at least partially absorbs light in a wavelength range from 500 to 600 nm. The LED luminaire cover light diffuser achieves a relative value of spectral radiance at a wavelength of 450 nm within a range from 1.60 to 15 with the spectral radiance at the wavelength of 550 nm defined as 1, when the spectral radiance is measured with a specific white LED used as a measurement light source and with the LED luminaire cover light diffuser provided to cover the white LED.
