<P>PROBLEM TO BE SOLVED: To provide a lighting system with a low insect-inducing property using an LED light source, which can lessen an inducible property of flying insects at low cost without spoiling a color tone of irradiating light. <P>SOLUTION: The lighting system has an LED section having an LED element for emitting light with a blue peak wavelength on a purple/blue wavelength band, and a phosphor for converting the wavelength of light emitted from the LED element. The phosphor has a plurality of wavelength conversion elements containing an yellow phosphor and a band interruption filter, the emitted light from the LED elements becomes white light based on blue light and yellow light, and the spectrum of the emitted light is formed so as to cause its light-emitting intensity at a wavelength band of 480-520 nm to substantially become zero. Thus, the lighting system can lessen the insect-inducing property of flying insects at low cost without spoiling the color tone of the white irradiating light and adding another LED element since the LED section can cause the light-emitting intensity of the emitted light to substantially become zero at the wavelength band of 480-520 nm contained in a visible light zone for inducing insects and having fewer contribution to white light. <P>COPYRIGHT: (C)2012,JPO&INPIT |
