JPH10162614A - Air-handling luminaire - Google Patents

Abstract

PROBLEM TO BE SOLVED: To adjust the air quantity with a simple structure, control light distribution, and reduce the infiltration of dust into the inside and noises by arranging adjusting plates made vertically movable along the open ports for air-handling provided on both side walls in the longitudinal direction of a long luminaire body opened with the lower face and formed into reflecting faces on the surface. SOLUTION: Open ports 13 for air-handling are provided at both ends except for a part on both side walls in the longitudinal direction of a long reflector 12 stored in a long luminaire body 11, and they are located above a light source. The air quantities passing through the open ports 13 are adjusted by adjusting plates 14 vertically moved in the reflector 12 along the open ports 13 and having bent pieces at the upper end sections. The inner surfaces of the adjusting plates 14 are formed into reflecting faces by white coating or aluminum mirrors, and light distribution is controlled. The height of the adjusting plates 14 is adjusted to reduce noises in response to the quantity and speed of the air cooling the light source. The luminaire body 11 is supported in the ceiling by support metals 16.

There is a drawback that the work of attaching and detaching the reflector requires time and effort. Further, if the distance between the lighting fixture body and the auxiliary reflector is small, there is a disadvantage that noise is generated when air passes through the same part. Further, if an opening is provided in the upper wall in the longitudinal direction of the lighting fixture body, there is a disadvantage that dust behind the ceiling enters the interior of the lighting fixture.
