この考案は、空調設備を有する室内に設置する
螢光ランプの照度低下防止照明器具に関するもの
である。[Detailed Description of the Invention] Industrial Field of Use This invention relates to a lighting fixture that prevents a decrease in illuminance of a fluorescent lamp installed in a room equipped with air conditioning equipment.

明器具が用いられていた。BACKGROUND TECHNOLOGY Conventionally, a ceiling-embedded lighting device installed in a room equipped with an air conditioner has a fluorescent cover/reflector plate 15 with an open lower part 14 that covers the top surface 12 and side surface 13 of a fluorescent lamp 11, as shown in FIG. A lighting fixture was used in which a suction hole 16 was formed in the upper surface 12 above the light lamp 11.

照度が低下する問題点があつた。Problems to be Solved by the Invention In the above-mentioned conventional lighting equipment, a suction hole is provided on the top surface of the fluorescent lamp, so indoor air is drawn from the suction hole into the fluorescent lamp by the disposal device of the air conditioning equipment, as shown by the arrow. The problem is that the air is sucked along the surface of the lamp, and the fluorescent lamp is cooled by this flow of air, resulting in a reduction in illuminance, particularly during cooling, in which the illuminance decreases by about 10% to 15%.

止照明器具からなるものである。Means for Solving the Problems The means of this invention for solving the above problems is that the lower surface 7 is open and the cover/reflector plate 5 covering the upper surface 3 and the side surfaces 4 is provided with a cover/reflector plate 5 that extends along the length of the straight tube fluorescent lamp 2. This is a lighting fixture that prevents a decrease in illuminance and has an air suction hole 8 that is always open on the side surface 4 diagonally below the side of the direction.

れている。 Reference numeral 1 denotes a ceiling plate, and a cover/reflection plate 5 is installed inside the ceiling plate to cover the upper surface 3 and side surface 4 of the ceiling straight tube fluorescent lamp 2. 6 is a stabilizer. The cover/reflection plate 5 has an open lower surface 7 and is provided with an air suction hole 8 that is always open on the side surface 4 diagonally below the longitudinal side of the straight tube fluorescent lamp 2.

が得られた。 When the exhaust device (not shown) of the air conditioner is activated, air from the room 9 is sucked into the ceiling 10. At this time, the air in the room 9 flows from below toward the suction hole 8 so as not to hit the straight tube fluorescent lamp 2, as shown by the arrow, so that the cooling of the straight tube fluorescent lamp 2 is hardly affected. It has no effect. As a result, the 700 lux directly under the straight tube fluorescent lamp when the air conditioner was not operating was now 700 lux when cooling.
However, according to this example, it was possible to obtain 690 lux, which was almost the same as when the air conditioner was not operating.

ができる。Effects of the invention This invention eliminates the fact that the straight tube fluorescent lamp is not cooled by the exhaust air when the air conditioner is activated, which reduces the 10% to 15% that occurs due to low temperatures as in the past.
There is no decrease in illuminance of about 10%, and the maximum efficiency of a straight tube fluorescent lamp can be maintained even during cooling.
