Abstract

PURPOSE: To improve a maintenance rate and lessen the number of times of cleaning, by using a gap formed by adjacent end edges of lateral faces of divisional reflectors covering fluorescent lamps, as an air circulation hole for air conditioning. CONSTITUTION: Reflectors 5 respectively having a single reflective surface are mounted to two fluorescent lamps, and a gap is formed between the adjacent reflectors 5 to use as an air circulation hole for air inlet port. And both sides aperture edges of the reflectors 5 covering the fluorescent lamps 7 are positioned below the bottom ends of the fluorescent lamps 7. Therefore, the air for the air conditioning does not flow on the surfaces of the fluorescent lamps 7 and the reflectors 5, even when the gap is used as an inlet port or a blow outlet. Thereby, dust does not attach to the fluorescent lamps 7 and reflective surfaces of the reflectors 5, thus a high maintenance rate can be kept.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system ceiling lighting fixture that also has an air conditioning function.

[Conventional technology]

A system ceiling is constructed by extending a large number of beams in parallel along the ceiling surface, and mounting ceiling plates and lighting fixtures on the beams. The above-mentioned system ceiling lighting equipment is composed of a mounting leg for mounting the main unit on the beam, a main body to which a lamp socket, etc. is attached, a separator that covers the lamp socket, a ballast tube, a reflector plate, etc. However, as shown in Fig. 4, the air conditioning system used in combination with the system ceiling lighting equipment has conventionally used a double-beam (double-bar one-way type) air outlet and a differential user 8 to blow out the air. Or, make it a single bar type and attach the anemo to the equipment plate mounted on the ceiling board. Further, for the suction, in the case of the double-bar one type, one of the bars is used as a return slit, or as in the case of the single-bar one type, an air circulation port is provided in the reflector plate 5 to serve as the suction port.

[Problem that the invention seeks to solve]

Each of the above conventional techniques has the following problems.

(1) When the reflector is provided with air flow holes, indoor dust and the like adhere to the reflective surface of the reflector and the lamp, reducing lighting efficiency and causing insufficient illuminance, as well as increasing cleaning costs.

(2) As the number of equipment such as fire detectors, sprinklers, and broadcasting equipment increases, the single bar system does not have enough space to store anemones, resulting in a capacity shortage. Further, although the above-mentioned problem does not occur in the double bar type, there is a problem in that the equipment cost increases.

(3) High-quality glare-cut lighting is important for the indoor environment, but with conventional methods, the lamp must be placed high, which requires a deep reflector and increases the cost of lighting equipment. .

It was necessary to secure a hole in the space behind the attic. However, with a deep reflector, the mounting pitch of the lighting equipment is generally as wide as 3 m to 3.2 m, which poses a problem of poor symmetry.

SUMMARY OF THE INVENTION An object of the present invention is to obtain a ceiling lighting fixture for an air conditioning system that solves the above-mentioned problems, has a high maintenance rate and fixture efficiency, and is low cost.

Means for Solving Problem c] The above object is to divide the reflector plate into each lamp, use the gap between the divided reflector plates as an air flow hole, and place the air flow hole below the lower end of the lamp. This is achieved by providing

[Effect]

The divided reflectors cover the lamps and are fixed to the fixture body with screws, but the lower ends of each of the reflectors are located below the lower end of the lamp to form an air flow opening, so the air flow is limited. Since the air blown out or sucked in from the mouth does not pass through the lamp or reflective surface, these lamps and reflective surfaces are not contaminated with dust or the like.

Furthermore, since the reflector has an independent shape for each lamp, the height of the lamp required for glare reduction can be reduced. In addition, since each lamp has a reflective surface covering both sides, the efficiency of the ceiling lighting system can be improved.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view showing one embodiment of the air-conditioning system ceiling lighting fixture according to the present invention, FIG. 2 is a perspective view showing another embodiment of the above-mentioned system ceiling lighting fixture, and FIG. FIG. 4 is a sectional view showing still another embodiment of the system ceiling lighting fixture. In Figures 1 and 2, the appliance body 2 is mounted via mounting legs 3 on two beams (T-bars) 1 placed parallel to each other along the ceiling surface, and has lamps at both ends. A separator 6 connects the two T-bars by covering the lamp sockets, and a ballast box 4 is attached to the upper part of the main body 2.6 In the embodiment shown in FIG. A reflecting plate 5 having a single reflective surface is attached to each of the fluorescent lamps, and a gap is provided between the adjacent reflecting plates 5, and the gap is used as an air circulation port and an intake port. Also,
In other embodiments shown in FIGS. 2 and 3, a differential user 8 is attached along the longitudinal direction of the gap and used as an air outlet. However, in any of the above embodiments, the opening edges on both sides of the reflecting plate 5 covering the fluorescent lamp 7 are configured to be located below the lower end of the fluorescent lamp 7. Therefore, regardless of whether the gap is used as an inlet or an outlet, the flow of air conditioning air does not use the fluorescent lamp 7 or the surface of the reflector S as a flow path.
Dust does not adhere to the fluorescent lamp 7 or the reflective surface of the reflective plate 5, and a high maintenance rate can be maintained.

Further, since the reflecting plate 5 forms an independent reflecting surface for each fluorescent lamp 7, it is possible to obtain high equipment efficiency. In addition, having an independent reflector 5 for each fluorescent lamp 7 makes it possible to lower the position of the fluorescent lamp 7, making it easier to cut glare and create a system ceiling lighting fixture with a shallow embedding depth. is obtained.

Still another embodiment shown in FIG. 4 is an example in which the shape of the reflecting plate 5 is formed asymmetrically with respect to the fluorescent lamp 7, thereby giving directionality to the light distribution of the lighting equipment. You can get good symmetry even when installing.

〔Effect of the invention〕

As described above, the ceiling lighting fixture for an air-conditioning system according to the present invention is a reflection light fixture installed in one segment in the ceiling lighting fixture for an air-conditioning system that is mounted on a beam stretched parallel to the ceiling surface. By using the gap formed by the adjacent edges of the side surface of the plate that covers the fluorescent lamp as an air flow opening for air conditioning, the following effects are achieved.

(1) The reflective surfaces of fluorescent lamps and reflectors are resistant to dirt.
The maintenance rate is improved and the number of cleanings is reduced, so running costs can be reduced.

(2) Since the single bar type can be used for both blowing and suction, it is possible to reduce the initial cost compared to the double bar type.

(3) Since the reflector forms a unique shape for each fluorescent lamp, the efficiency of the fixture is improved and the uniformity of illumination can be improved.

(4) To cut glare, the fluorescent lamps can be kept low and the lighting fixtures can be embedded shallowly, reducing the cost of the lighting fixtures and reducing the required depth behind the ceiling. It is possible.
