Description

  The present invention relates to a structure for installing a lighting fixture in a room maintained in a special environment.

  In various laboratories, animal breeding rooms, plant cultivation rooms, etc., the indoor environment may be maintained under special conditions such as high temperature and high humidity. Standard lighting equipment should be installed in such special rooms. Since stable operation and longevity are not guaranteed, early failure and frequent maintenance are inevitable, and therefore special lighting fixtures such as high-temperature specifications and waterproof specifications are usually installed to deal with special environments.

Moreover, since it is preferable to install the lighting fixture in such a special room in a concealed state as much as possible rather than in an exposed state that is easily exposed to a special environment, for example, when installing in the upper part of the room Is generally embedded in the ceiling rather than being directly attached to the ceiling surface, and such an embedded lighting device as shown in Patent Document 1 or Patent Document 2 is known as such an embedded lighting device. It has been.
This is a structure in which a housing containing a light source is embedded in the ceiling, the lower opening thereof is closed with a lid, and a light guide light-emitting plate is attached to the lid. It is installed in a concealed state inside, and the illumination light is guided by the light guide light emitting plate by the illumination light from the light source so that the entire light guide light emitting plate emits light indoors to obtain an illumination effect. .

However, special lighting fixtures are not only relatively expensive compared to standard lighting fixtures, but often require special maintenance, even if they are special, and if exposed to a special environment for a long time. Problems remain in durability and maintainability.
In addition, although the surface illumination devices as shown in Patent Documents 1 and 2 are concealed in the back of the ceiling, the light source and the case are concealed in the interior, but the cover attached to the case is exposed indoors, Therefore, a sufficient concealing effect cannot be expected, and the durability and maintainability are still difficult. Moreover, since it is assumed that the influence of heat generated by the light source reaches the room, it is difficult to apply when strict temperature control is performed.

  In view of the above circumstances, an object of the present invention is to provide an effective and appropriate structure capable of installing a standard luminaire without any trouble in a special room.

  The present invention is directed to a special room, which is formed by partitioning from the surroundings with a partition plate to maintain the indoor environment under special conditions such as high temperature and high humidity. The lighting fixture includes a fixture main body in which a light source lamp is accommodated in a casing, and a light guide light emitter mounted on the fixture main body, and is formed at the bottom of the casing. When the base of the light guide light emitter is attached to the slit, the illumination light from the light source lamp is guided through the light guide light emitter, and the light guide light emitter itself emits light in a special room, The instrument body is disposed outside the partition plate, the bottom of the housing is brought into close contact with the outer surface of the partition plate, and the partition plate is cut off at the position of the slit formed in the housing to guide the guide. Insert a light emitter A slit-shaped opening is formed, and from the inside of the special chamber, the base of the light guide light emitter is placed in the instrument body through the opening formed in the partition plate and the slit formed in the housing. The gap between the light guide light-emitting body and the opening is sealed with a sealing material.

  The light guide light emitter is a resin molded plate having translucency such as a thick transparent acrylic plate, and a notch portion for scattering the guided illumination light on a desired surface of the light guide light emitter. What formed is suitably employable.

According to the present invention, it is possible to obtain a sufficient illumination effect by guiding the illumination light from the light source lamp by the light guide light emitter and causing it to emit light in the special room. Since the gap between the openings formed in the partition plate for sealing the light guide light-emitting body to be inserted outside is sealed with a sealing material, the adverse effect of the special environment maintained in the special room will affect the instrument body There is no room for it, and therefore, a general standard specification is sufficient for the main body of the instrument, and the cost can be sufficiently reduced as compared with the case of using a special specification, and maintenance can be reduced.
Moreover, various illumination effects can be obtained by forming a notch for scattering the illumination light in the light guide light emitter at an arbitrary position and in an arbitrary shape.

An embodiment of the present invention will be described with reference to FIGS.
This embodiment is an application example to a room for cultivating moss, for example, and its indoor environment is maintained at high temperature and high humidity, and in particular, the indoor relative humidity is always maintained at 100%.
As described above, installing a standard lighting device in a room with such a special environment does not guarantee normal operation, and a special lighting device that can ensure a high degree of moisture resistance is expensive. Therefore, in this embodiment, the lighting fixture similar to the surface illumination device as shown in Patent Documents 1 and 2 is installed with the following structure.

  In the figure, reference numeral 1 denotes a special room, and 2 denotes a partition plate that partitions the ceiling. Although only the partition plate 2 corresponding to the ceiling of the special room 1 is shown in the figure, the special room 1 is naturally divided not only into the ceiling but also into the wall surface and the floor surface. It is isolated from the environment (usually normal temperature and humidity) and can be maintained in the special environment as described above.

The lighting fixture 3 in the present embodiment includes a fixture main body 4 installed outside the partition plate 2 and a light guide light emitter 5 installed in a state of being inserted through the partition plate 2 and attached to the fixture main body 4.
The instrument main body 4 is configured by housing a light source lamp 6 made of a fluorescent lamp in a long casing 7 having a rectangular cross section. One side of the casing 7 can be opened and closed as an inspection port 8. A slit 9 for mounting the light guide light emitting body 5 is formed in advance at the bottom of the body 7.
The light guide light-emitting body 5 functions in the same manner as the light guide light-emitting plate in the surface illumination devices shown in Patent Documents 1 and 2, and its base portion (upper edge portion in the illustrated example) extends from the slit 9 described above. By being inserted into the housing 7 and guiding the illumination light from the light source lamp 6, the light guide light emitter 5 itself emits light in the special chamber 1 to obtain an illumination effect.
In the present embodiment, a resin molded plate such as a thick transparent acrylic plate is used as the material of the light guide light emitter 5. Further, the width dimension of the light guide light emitter 5 in the illustrated example corresponds to the length of the fluorescent lamp as the light source lamp 6, and light is emitted downward from the entire front end surface (lower end surface) of the light guide light emitter 5. However, light is also emitted obliquely from the triangular cutout 10 formed on one side of the light guide light emitter 5.

In order to install the lighting fixture 3 having the above configuration on the partition plate 2, as shown in FIG. 2A, a slit shape for cutting the partition plate 2 and inserting the light guide light emitting body 5 at the installation position is provided. The opening 11 is formed in advance, the instrument body 4 is arranged outside thereof, the bottom surface of the housing 7 is brought into close contact with the outer surface of the partition plate 2, and the slit 9 and the opening 11 are matched. At that time, by opening the inspection port 8 on the side of the housing 7, the work inside the housing 7 can be performed without any trouble.
Then, from the inside of the partition plate 2 (that is, from the inside of the special chamber 1), the base of the light guide luminous body 5 is inserted into the housing 7 through the opening 11 and the slit 9, and is appropriately connected and fixed to the housing 7. After that, as shown in FIG. 2B, the gap between the opening 11 and the light guide light emitter 5 is sealed with an appropriate sealing material 12 so as to be able to maintain water tightness and air tightness. Become.

If the lighting fixture 3 is installed in the partition plate 2 by the above structure, the illumination light from the light source lamp 6 is guided by the light guide light emitter 5 and emitted in the special chamber 1 to obtain a sufficient illumination effect. Of course, the entire instrument body 4 is completely disposed outside the partition plate 2, and the gap between the openings 11 formed in the partition plate 2 for the light guide light-emitting body 5 to be inserted is sealed by the sealing material 12. Therefore, the instrument body 4 is installed outside the special room 1 in a state of being completely concealed.
Therefore, there is no room for the adverse effect of the special environment such as high temperature and high humidity maintained in the special chamber 1 to reach the instrument body 4. Of course, although the light guide illuminant 5 is installed in the special chamber 1 in an exposed state, it is made of a simple resin molded plate, so there is no concern that it will have any adverse effect on it.
Therefore, the lighting fixture 3 of this embodiment, in particular, the fixture main body 4 does not have to have any special specification, and a standard specification similar to a general lighting fixture is sufficient, and construction for installing this is also possible. However, it is not particularly troublesome as compared with the conventional installation of lighting equipment.

From the above, by installing the lighting fixture 3 with the above-described structure, the initial cost and the running cost can be sufficiently reduced as compared with the case of using a lighting fixture of a special specification as in the past. Further, as compared with a case where a surface illumination device as shown in Patent Documents 1 and 2 is installed in a semi-concealed state, its operation and life can be guaranteed more reliably, and maintenance can be reduced.
Moreover, since the instrument body 4 is installed in a completely concealed state and is completely isolated from the special room 1, even if the instrument body 4 generates heat, the influence does not reach the special room 1. Therefore, this is particularly effective when the temperature in the special room 1 is strictly controlled.

Although one embodiment of the present invention has been described above, the above embodiment is merely a preferred example, and the present invention is for installing the instrument body 4 outside the special chamber 1 and passing the light guide light emitter 5 therethrough. As long as the opening portion 11 is formed in the partition plate 2 and the gap between the opening portions 11 is sealed with the sealing material 12, the specific configuration of the other details is arbitrary. For example, the following design changes And can be applied.
In the above embodiment, the case where the lighting fixture 3 is installed on the partition plate 2 that forms the ceiling of the special room 1 has been described. However, the partition plate 2 that forms the wall surface of the special room 1 or if necessary. Needless to say, the lighting fixture 3 can be installed with the same structure on the partition plate 2 forming the floor.
Further, the lighting fixture 3 in the above embodiment has the light source lamp 6 as a fluorescent lamp, and thus the light guide light emitter 5 is a flat plate having a width corresponding to the length of the fluorescent lamp. Various types of lamps can be used, not limited to fluorescent lamps, and the shape of the light guide light emitter 5 can be appropriately set, for example, in the form of a rod or a block.
In addition, the light guide light emitter 5 is not simply a flat plate or a straight rod, but can be bent into a desired curved shape or curved shape, for example, so that the illumination light from the light guide light emitter 5 can be bent. It is also possible to emit light in a desired direction.
Furthermore, in the said embodiment, although the triangular-shaped notch part 10 for scattering illumination light was provided in the single side | surface of the light guide light-emitting body 5, the cross-sectional shape and formation of the notch part 10 are also included including abbreviate | omitting it. The position is arbitrary, and various lighting effects can be obtained by forming the notch 10 having a desired shape at a desired position.

It is a perspective view which shows the installation structure of the lighting fixture which is embodiment of this invention. It is a side view which shows a construction procedure same as the above.
