Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting fixture with an air blower installed on the ceiling side, such as by being directly attached to the ceiling or suspended from the ceiling.

[Conventional technology]

Conventionally, all lighting fixtures provided for general household use are only for illumination, and there are no lighting fixtures that include a blower device. Therefore, in order to improve the indoor environment by dealing with cigarette smoke and unpleasant smells, for example, wall-mounted or indoor-installed air purifiers are purchased and installed separately from lighting equipment. In addition to general household lighting equipment, commercial lighting equipment that lights offices in buildings is provided with lighting equipment that is suitable for use in combination with central air conditioning equipment for buildings. This commercial lighting fixture is a ceiling-embedded type, with a cover provided on the outside of the reflector that covers the lamp from above. The suction space and the outlet space that are formed are connected to air conditioning ducts installed on the ceiling side of the building, respectively, and air conditioning y!
2) The system is configured so that indoor air is sucked in, removed from the room, air-conditioned, and then discharged back into the room to condition the air in the room.

[Problem that the invention seeks to solve]

However, if you purchase and install an air purifier separately from the lighting equipment as in the former case, the equipment costs will increase and the indoor space will become cluttered as these equipments are placed separately. There was a problem that it was easy to get wet. Also,
The ceiling-embedded commercial lighting fixtures mentioned above not only have large vertical dimensions, but also have the problem of being extremely expensive in terms of equipment, as they must be combined with air conditioning equipment. Because of the TIJ bottom, it was impossible to repurpose such lighting equipment for general household use as is.

[Means for Solving the Problems] The present invention provides a wind guide plate on a device body, and connects the device body with the guide plate as a boundary, and a lighting device portion whose lower surface forms a light projection surface. It is divided into a blowing section which is integrally adjacent to the side of the fixture section and has an inlet and an outlet on the bottom and side surfaces, and the lighting fixture section incorporates a lamp and its lighting parts, and the blowing section. has a built-in fan motor, and among the lighting parts mentioned above, the parts that generate heat are
It is characterized in that it is disposed on the wind guide plate on the side of the air blowing part in a thermal conductive manner.

[Effect]

The lighting fixture with a blower device of the present invention is used by being attached directly to the ceiling of a general household, or by being attached to the ceiling by being suspended from the ceiling. This lighting fixture with a blower ff1Hffi has a structure in which the blower part is integrally adjacent to the side of the lighting fixture part, so it does not become thicker vertically. When the fan motor is operated in this lighting fixture, indoor air is sucked in through the intake port of the blower and blown out from the outlet, allowing indoor air to be circulated starting from the lighting fixture with the blower device. . Therefore, there is no need to install an air purifier or the like indoors, and there is no longer a restriction that it must be used in conjunction with an air conditioning system that has an air conditioning duct installed in the ceiling. It can be used as

Of course, the indoor air circulation effect described above can equalize the indoor temperature, and if a deodorizing filter or the like is built into the blower, it can eliminate cigarette odors and improve the indoor environment. The III guide plate, which is provided to partition the lighting equipment section and the air blower section, guides the air passing through the air blower section when the fan motor is operating, so this air guide plate is made thermally conductive and placed in the lighting equipment section. The heat of the heat-generating lighting component can be quickly radiated from the wind guide plate to the wind passing through the blowing section, thereby reducing the temperature rise of the heat-generating lighting component.

Thereby, it is possible to promote downsizing and increase in illuminance of the lighting fixture, and it can be made suitable as a fixture for general household use.

(Example〕 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is the instrument body made of sheet metal, and 2 is an auxiliary plate made of sheet metal etc. that is removably attached to a part of the instrument body 1, and this is flush with the outer surface of the instrument body 1. It is provided.

A wind guide plate 3 made of sheet metal is installed inside the appliance main body 1 and also serves as a partition. I! The I guide plate 3 divides the fixture body 1 into a lighting fixture part 4 whose lower surface forms a light projection surface 4a, and a ventilation part 5 integrally adjacent to the side of the lighting fixture part 4. It's in charge. In addition, in this embodiment, since a pair of left and right lighting equipment parts 4 are provided, two wind guide plates 3 are used, and these are arranged so as to face each other in the center of the equipment main body 1. A case is shown in which a blower section 5 is formed between the plates 3, and the outer surface of the blower section 5 is formed by the auxiliary plate 2 of the instrument main body.

Each lighting fixture section 4 incorporates a lamp 6 and its lighting components (only the ballast 7 is shown).

As the lamp 6, for example, a U-shaped fluorescent lamp, etc., which is small and capable of high-level illumination, is used. In addition, among the lighting parts, parts that dissipate heat, such as the ballast 7, are placed closer to the air blower 5 side and are arranged so as to be thermally conductive to the air guide plate 3. In the case of the embodiment, the case is shown in which it is attached directly to the wind guide plate 3 to achieve the most efficient heat conduction, but it may also be attached to a support plate, which will be described later.

Moreover, in this first example, in order to simplify the attachment and detachment of the lamp 6 and to eliminate the need to secure a space for attaching and detaching the lamp 6 in the length direction of the lighting fixture section 4,
The following structure is adopted. In other words, a support plate 8 bent into a substantially rectangular shape is rotatably attached to the lighting equipment section 4 on the side of the ventilation section 5 via a pivot shaft 9 that engages near the bent portion of the support plate 8. The lamp 6 is removably attached to the vertically arranged portion of the lamp via a lamp socket 10. The lamp 6 can be attached or detached by rotating the support plate 8, as shown in FIG.

In the figure, reference numeral 11 denotes a plate-shaped light control body, one end of which is connected to a clamping plate 12 that is screwed to a portion placed next to the support plate 8.
The plate-like light control body 11 is connected and supported by the light-emitting device 4, and the plate-like light control body 11 is arranged to be completely housed in the light projection surface 4a of the lighting fixture section 4. At the same time, the plate-shaped light control body 11 passes through the tip thereof and attaches to the screw receiver 13 attached to the end plate 4b of the lighting equipment section 4.
A decorative screw 14 screwed into the projection surface 4a allows the projection surface 4a to maintain its position within the projection surface 4a. The illustrated plate-shaped light control body 11 is an integrally molded product made of a milky-white synthetic resin in the form of a lattice. It is also possible to omit the light body 11.

The blowing section 5 is provided with an inlet 15 on the lower surface of the auxiliary plate 2 forming the outer shape of the device body, and is also provided with an outlet 16 on at least one side surface. Note that the suction port 15 and the blowout port 16 may be arranged in reverse.

Furthermore, the fan motor 17 is built into the blower section 5 and includes a motor 17a and a fan 17b connected to its rotating shaft. Further, the wind guide plate 3 is formed with a through hole 18 that communicates between the upstream side of the fan motor 17 in the ventilation section 5 and the interior of the lighting fixture 14 . Moreover, although it is not necessarily required, in this embodiment, the air blowing section 5
A removable air filter 19 and a deodorizing filter 20 are housed downstream of the through hole 18 .

Note that 21 in FIG. 1 indicates a filter support plate.

Sending the above configuration! 1′! The A-mounted lighting fixture is located, for example, approximately in the center of a room in a general household, and is used by being attached directly to the ceiling, or by being attached to the ceiling by being suspended from the ceiling.

This send! Since the lighting fixture with the L device has a structure in which the blowing part 5 is integrally adjacent to the lighting fixture part 4 not on the upper side or the lower side thereof but on the side thereof, it does not become thicker vertically.

When the fan motor 17 is operated in this lighting fixture, indoor air is sucked in from the suction port 15 of the ventilation section 5 and the fan of the fan motor 17 is operated, as shown by the solid arrow in FIGS. 1 and 2. Pass through 17b, air outlet 1
Since the air is blown into the room from 6, the indoor air can be circulated starting from the lighting fixture with the blower installed in the center of the ceiling side channel in the room.

Therefore, there is no need to install an air purifier or the like in the room separately from the lighting fixture with the feeding device, and the equipment can be simplified and the room will not be cluttered. Moreover, it must be used in conjunction with air conditioning equipment that has air conditioning ducts installed in the ceiling!
There is no need for i11, and it can be installed inside the cylinder on the ceiling side of ordinary homes.

Of course, the indoor air circulation effect as described above can equalize the indoor temperature, and in this embodiment, the air blower 5
Since it has one built-in air filter and a deodorizing filter 20, it is possible to eliminate or collect cigarette odors etc. by circulating indoor air. This can improve the indoor environment.

The wind guide tfj3, which is provided to partition the lighting equipment section 4 and the air blowing section 5, is configured to separate the lighting equipment section 4 and the air blowing section 5 when the fan motor 7 is operated.
guide the air through. Therefore, the wind guide plate 3 is made to be thermally conductive so that the heat from the heat-generating lighting components (ballast 7, etc.) arranged in the lighting equipment section 4 is transferred from the wind guide plate 3 to the wind passing through the blower section 5. Heat is quickly dissipated, and the temperature rise of the lighting heat generating component 7 can be reduced. Thereby, it is possible to promote downsizing and increase in illuminance of the lighting fixture, and it can be made suitable as a fixture for general household use.

Moreover, in this embodiment, since the air guide plate 3 is provided with the through hole 18, the fan motor 17 sucks air not only from the suction port 15 but also from inside the lighting fixture section 4 through the through hole 18. That is, as shown by the dotted line arrow in FIG. 18 and is sucked into the blower section 5. Therefore, the heat-generating lighting component 7 can be air-cooled by such an air flow, and its temperature rise can be further reduced.

Although the above-described embodiment is configured as described above, in the present invention, the filter may be omitted, and either one of the lighting equipment sections may be omitted. In addition, in carrying out the present invention.

Unless it goes against the gist of the invention, the specific structure of the appliance body, guide plate, lighting fixture section, light projection surface, ventilation section, suction port, air outlet, lamp, lighting parts, fan motor, through hole, etc. It goes without saying that the shape, position, material, etc., are not limited to the above-mentioned examples, and can be implemented in various configurations (different configurations).
