<P>PROBLEM TO BE SOLVED: To provide a luminaire attracting no insect even if it is lighted, by turning all of emission light emitted to the outside into one having low insect attracting properties while maintaining heat radiating performance. <P>SOLUTION: This luminaire is provided with a light source 11, a luminaire enclosure 12 for storing the light source 11, an opening part 13 for emitting emission light to the outside, a direct emission preventing section 15 for preventing the emission light from being directly emitted to the outside from the light source 11, and a selectively cutting section 16 for removing short wavelength light having insect attracting properties and a wavelength of not more than 410 nm. The selectively cutting section 16 is provided so as to reflect the emission light at least once before the emission light is emitted from the opening part 13, and the emission light going toward a light projecting opening 13a is projected after the short wavelength light is removed by a light transmitting panel 16a forming the selectively cutting section 16. In addition, the short wavelength light is removed from the emission light emitted from a heat radiating hole 13b by the selectively cutting section 16 provided on the inner surface of the luminaire enclosure 12. Since the emission light having low insect attracting properties is emitted from all opening parts 13, this luminaire attracts no insect. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
