Description

  The present invention relates to an illuminating device such as an emergency light or a guide light attached to a wall surface, and relates to an illuminating device that distributes light from a light source in a maximum of three external directions.

  An illuminating device such as an emergency light / guide light includes, for example, a straight tube lamp as an emergency light source, and is configured to distribute light of the light source at least in front of the outside, and further above and / or below the outside. There are also light distributions (for example, see Patent Document 1).

  In emergency lights, the use of combustible materials within a range of 50 mm or less around the emergency light source is prohibited. For this reason, when light is emitted from the light source not only to the front and lower sides of the outside but also to the upper side, the glass having translucency is held on the upper surface of the cover that covers the light source. It is necessary to form a frame part. On the other hand, when the light from the light source is distributed only to the front and the outside, the entire upper surface of the cover can be made of a light-shielding metal or the like.

Japanese Patent Laid-Open No. 10-289613

  As described above, in the conventional lighting device, it is necessary to prepare two types of designs having different appearances and different shapes of the upper surface of the cover covering the light source depending on whether or not the light from the light source is distributed upward. As a result, the manufacturing cost increases. Further, it is not possible to give a sense of unity in design to a place where two types of lighting devices having different upward light distribution states are used together.

  The object of the present invention is to deal with both the case where light from the light source is distributed upward and the case where the light is not distributed upward in a single appearance, which can realize a reduction in manufacturing cost and upward. An object of the present invention is to provide an illuminating device capable of giving a design unity to a place where two types of illuminating devices having different light distribution states are used together.

  The lighting fixture of this invention is provided with a light source, a cover, and first and second incombustible members. The cover includes a first surface facing the front surface of the light source with a predetermined interval and a second surface facing the upper surface of the light source using a translucent resin plate as a material. The first incombustible member is a light shielding plate material. The second incombustible member is a glass plate. The first and second incombustible members are alternatively disposed between the light source and the second surface of the cover.

  Regardless of whether or not the light from the light source is distributed upward, the front and top surfaces of the external appearance of the apparatus are constituted by the cover. A light source is positioned inside the cover that constitutes the appearance, and light from the light source is distributed to the outside front via the first surface of the cover. When the first incombustible member is used, light upward from the light source is shielded by the first incombustible member and is not distributed outside from the second surface of the cover. When the second incombustible member is used, the light upward from the light source is distributed to the outside through the second incombustible member and the second surface of the cover. When this configuration is used for an emergency light, the predetermined distance between the first surface of the cover and the light source needs to be the distance defined in the emergency light technical standard JIL5501, but the second surface of the cover and the light source Since the 1st or 2nd incombustible member is located between, the space | interval of both is not restrict | limited.

  In this configuration, it is preferable that the first and second incombustible members are joined to the second surface of the cover. The vertical size can be minimized.

  Moreover, it is preferable to provide the side plate which coat | covers the side surface of a light source and a cover, and fixes a cover and a 1st or 2nd nonflammable member via a side plate. The structure can be simplified.

  According to the present invention, it is possible to cope with both the case where the light of the light source is distributed upward and the case where the light is not distributed upward with a single appearance design, which can realize a reduction in manufacturing cost and Design uniformity can be given to a place where two types of lighting devices having different light distribution states are used together.

It is an assembly drawing of the illuminating device which concerns on embodiment of this invention. It is an assembly drawing of the cover 3 of the illumination device. (A) And (B) is side sectional drawing of the same illuminating device.

  Hereinafter, an illumination device according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the illuminating device 10 which concerns on embodiment of this invention is equipped with the emergency light source 1, the main body 2, the cover 3, the side plate 4, and the sensor 5, and is used as an emergency light.

  The emergency light source 1 is a straight tube lamp as an example, and is held on the front side of the main body 2 with the longitudinal direction horizontal. The emergency light source 1 does not necessarily have to be a straight tube lamp, and may be constituted by, for example, a long LED lamp or a plurality of spherical lamps. As an example, the main body 2 is formed by forming a metal plate material into a strip-like body longer than the emergency light source 1 by press working, and includes attachment portions 21 in which screw holes 21A are formed on both side ends. The main body 2 includes a reflector 22 on the front surface, and includes circuit components (not shown) between the reflector 22 and the main body 2.

  The sensor 5 senses the proximity of the human body by emitting radio waves and outputs a detection signal. The illuminating device 10 drives the emergency light source 1 when a detection signal is output from the sensor 5. The sensor 5 is fixed to the tip of a fixture 51 that extends forward from the center of the lower end of the main body 2.

  The cover 3 is formed in a uniform L-shaped cross section over a length comparable to the main body 2 using a single translucent resin plate as a material. The cover 3 is configured by bending a single translucent resin plate, but may be configured by joining a plurality of translucent resin plates. The cover 3 includes a first surface 31 that is a vertical surface as an example, and a second surface 32 that is a horizontal surface as an example. A notch 33 is formed at the center of the lower end of the first surface.

  As an example, the side plate 4 is formed into a three-sided housing shape that covers the side end portion of the cover 3 from the outside by pressing a metal plate material. A through hole 41 is formed in the side plate 4 at a position facing the screw hole 21 </ b> A of the attachment portion 21.

  When the emergency light source 1 is held on the main body 2 and the side plates 4 are attached to both ends of the cover 3, the cover 3 is put on the main body 2 from above, so that the first surface 31 of the cover 3 is attached to the emergency light source 1. The second surface 32 of the cover 3 faces the upper surface side of the emergency light source 1. Further, the sensor 5 is fitted into the notch 33 of the cover 3.

  By forming the cover 3 with a translucent resin plate, a notch having an arbitrary shape for arranging the sensor 5 at an arbitrary position on the front surface of the lighting device 10 can be formed, and the side plate 4 is used as in the case of using a glass plate. There is no need to place a sensor in The sensor 5 can be omitted, and in this case, it is not necessary to form a notch in the cover 3.

  The covering state of the main body 2 by the cover 3 is maintained by screwing the fixing screw 7 penetrating the through hole 41 of the side plate 4 into the screw hole 21 </ b> A of the main body 2. As a result, the front side and the top side in the appearance of the lighting device 10 are integrally configured by the cover 3. The bottom surface of the lighting device 10 is open.

  In the cover 3, the first surface 31 and the second surface 32 are not necessarily orthogonal to each other on the condition that the first surface 31 and the second surface 32 face the front surface side and the upper surface side of the emergency light source 1, respectively. Not a thing.

  As shown in FIG. 2, screw holes 32 </ b> A are formed on both ends of the second surface 32 of the cover 3. The incombustible member 6 is formed in the same shape as the second surface 32 of the cover 3, and screw holes 61A are formed at both ends. After the nonflammable member 6 is joined to the inner surface of the second surface 32 of the cover 3, the side plates 4 are screwed to both ends via the through holes 42 and the screw holes 32 </ b> A and 61 </ b> A. The incombustible member 6 is integrally fixed to the side plate 4 and the cover 3 and the incombustible member 6. The incombustible member 6 can also be disposed with a gap between the second surface 32, but by joining to the inner surface of the second surface 32, the height of the lighting device 10 can be minimized, The structure can be simplified most.

  The fixing of the side plate 4 and the incombustible member 6 to the cover 3 is not limited to screwing. Further, the incombustible member 6 can be attached to the inner surface of the cover 3 via an adhesive or the like.

  As shown in FIGS. 3A and 3B, a predetermined distance D <b> 1 is formed between the inner surface of the first surface 31 and the emergency light source 1 in a state where the cover 3 is placed on the main body 2. The distance D1 is 50 mm defined in the emergency light technical standard JIL5501. On the other hand, the incombustible member 6 is disposed between the second surface 32 and the emergency light source 1. For this reason, even if the distance D2 between the inner surface of the second surface 32 and the emergency light source 1 is less than 50 mm and the overall height of the lighting device 10 is reduced, the emergency light technical standard can be satisfied.

  As the incombustible member 6, either the light-shielding plate 6A that is the first incombustible member or the glass plate 6B that is the second incombustible member is alternatively used.

  As shown in FIG. 3A, when the light shielding plate 6 </ b> A is used, the light from the emergency light source 1 is forward of the lighting device 10 below the lighting device 10 and through the first surface 31 of the cover 3. Light distribution. The light shielding plate 6A is, for example, a metal plate.

  As shown in FIG. 3B, when the glass plate 6B is used, the light of the emergency light source 1 is illuminated through the glass plate 6B and the second surface 32 in addition to the lower side and the front side of the lighting device 10. The light is also distributed above the device 10.

  Since both the light shielding plate 6 </ b> A and the glass plate 6 </ b> B are arranged inside the second surface 32 of the cover 3, the appearance of the lighting device 10 is not affected. Further, even when the light of the emergency light source 1 is distributed above the lighting device 10, it is not necessary to have a configuration such as a frame for exposing and providing the glass plate 6B on the upper surface of the member constituting the outer surface. .

  Therefore, the lighting device 10 can be configured with a single translucent resin plate to form the upper surface and the front surface of the appearance regardless of whether or not the light from the emergency light source 1 is distributed upward. it can. Further, even when the lighting device 10 that distributes the light of the emergency light source 1 above and the lighting device 10 that does not distribute the light of the emergency light source 1 above are installed in the same place, the sense of unity in design is impaired. There is no.
