Light diffuser for LED lighting cover, LED lighting cover and LED lighting device

摘要

To provide a light diffuser for LED lighting covers, which effectively transmits light in a wide wavelength range including red light and brings about a superior diurnal pest control effect, and to provide an LED lighting cover and LED lighting device.SOLUTION: A light diffuser for LED lighting covers is provided, containing a base material resin and a light diffusing agent. The light diffuser for LED lighting covers is characterized in that, when spectral irradiance of transmitted light is measured using a white LED as a measurement light source, proportions of integrated values of spectral irradiance in different wavelength ranges to a total integrated value of spectral irradiance in a wavelength range of 360-780 nm are: 80% or greater in a wavelength range of 550-750 nm; 15% or grater in a wavelength range of 550-600 nm; and 10% or greater in a wavelength range of 650-700 nm.SELECTED DRAWING: Figure 1
