Description

[Detailed description of the invention] This invention relates to indicator lights such as guide lights.

Conventional guide lights are shown in FIGS. 1 to 3. That is, this device has a lamp socket 3 attached to the top plate 2 of a device box 1 with an open front, and a lamp 4 positioned in the center, and a bottom plate 5 equipped with a ballast 6, an electric block 7 incorporating inverter circuit parts, and a storage battery. Install 8. On the other hand, locking claws 10 are cut and raised on the inner surface of the frame 9 that is press-fitted into the front opening of the instrument box 1, and the display plate 11 is caulked thereto.
The frame 9 is fitted into the opening of the box 1.

However, this device has the following problems. That is, (1) Since the display board 11 is illuminated by direct light from the lamp 4, a certain distance must be maintained between the lamp 4 and the display board 11 in order to make the brightness distribution of the display board 11 uniform. There is a need. As a result, the depth dimension of the instrument box 1 increases, increasing the occupied space. Guidance lights are usually installed near aisles or floor exits, but if the depth dimension is large, they give an intimidating or foreign object feel.

(2) When installing the ballast 6, storage battery 8, etc. on the bottom plate 5, the opening of the instrument box 1 is unidirectional, making it difficult to use a screwdriver and resulting in poor workability and assembly.

(3) Since the display board 11 is caulked by a large number of locking claws 10 formed on the frame body 9, workability is poor, the locking claws 10 may break, and the display board 11 may wobble due to impact, etc. There is a risk that it will stick and come off, and it is difficult to remove, making maintenance difficult.

(4) When replacing the lamp 4 or storage battery 8, the frame 9
There is the trouble of having to remove it from the instrument box body 1.

(5) When installing guide lights on the ceiling or wall, it is difficult to install because it is necessary to procure special equipment and also remove the display board and lamp to install it on the top or back board. This also becomes a problem when the evacuation route changes due to rearrangement of rooms, etc., or when it is necessary to remove or change the direction. Furthermore, if mounting holes are formed in the top plate and the back plate, there are problems of light leakage and dust intrusion through the mounting holes that are not used.

(6) When installing the storage battery 8 in the appliance box 1, it is necessary to provide a heat radiation hole in the appliance box 1 in order to suppress the temperature rise of the storage battery 8 due to lamp light heat, but light leakage and dust intrusion may occur through this radiation hole. .

Therefore, the purpose of this invention is to provide a display board that solves the problems (1) and (3).

An embodiment of this invention is shown in FIGS. 4 to 14. In other words, this guide light is as shown in Figure 6.
The front surface 12a and the rear surface 12b of the lamp body 12 are integrally formed in a U-shape with the bottom surface 12c as a middle piece, and the front surface 12a has a display opening 12d, the bottom surface 12c has a transparent opening 12e, and the upper edge portions 12f of the front surface 12a and the rear surface 12b. , 12g are each formed with an inwardly bent portion.

As shown in FIG. 6, a light-transmitting panel 23 is installed and covered over the light-transmitting opening 12e of the bottom surface 12c of the lamp body 12.

An inclined reflection plate 24 close to the lower end of the front surface 12a of the main body 12 is slid and fitted into the gap 21 through the side opening of the main body 12 of the lamp. The reflector plate 24 is made of a material with high regular reflectivity such as mirror-finished aluminum, and is bent so that the upper end 24a and the lower end 24b are parallel to each other, as shown in FIGS. 7 and 8. At the same time, a folded line 24c having a length corresponding to the opening width (longitudinal direction) of the light-transmitting opening 12e is formed in the horizontal direction at the central portion, and the cut-and-raised piece 2
4d and a transparent opening 24e. By press-fitting the upper end 24a into the gap 21 from the side opening, the lower end 24b forms a certain gap 25 with respect to the lower end of the front surface 12a. In addition, the lower end of the cut and raised piece 24d contacts and is supported by the lower end of the rear surface 12b. Note that the lower end portion 24b of the reflecting plate 24 may be formed by bending a folded piece 24f so as to form the gap 25 as shown in FIG. 9, and the folded piece 24f may be supported in contact with the lower end portion of the front surface 12a. good.

The display plate 26 is press-fitted between the gaps 22 and 25 through the side opening of the lamp body 12, and positioned above the display opening 12d.

Furthermore, caps 27 and 28 molded from a resin material with low thermal conductivity are provided at both side openings of the lamp body 12.
to wear a crown. As shown in FIG. 10, the cap 28 has a battery storage recess 29 recessed on its outer surface.
It has an opening 29a at its upper end that communicates with the inside,
Further, a cover 30 for closing the recess 29 is removably locked in the opening 29a by a hook 30a at its upper end and supported by a lower end protrusion 30b.
This cover 30 has a support carrying plate 32 that supports the battery 31 inside. Further, the connector 33 is passed into the lamp body 12 through the opening 29a and connected to the connector 17.

On the other hand, in the center of the support plate 13, there are
As shown in the figures and FIG. 11, a cylindrical body 34 with a flange through which an electric wire can be inserted is erected, and an elastic ring 35 is fitted on the outer surface of the cylindrical body 34. The fixture body 36 for this is a U-shaped plate with an upper piece 36a and a middle piece 36b.
A wire insertion hole 36c and a mounting hole 36d are formed in the lower piece 36e, and a semi-circular notch 36f is formed in the lower piece 36e, and a retaining protrusion 36g is formed on the edge of the notch. It is attached to the wall by the middle piece 36b. Lower piece 36
The elastic ring 35 of the cylindrical body 34 is press-fitted into the notch 36f of e, and engaged by the collar 34a. In this case, the elastic ring 35 is caught on the protrusion 36g to prevent it from coming off. Further, the opening of the fixture body 36 is covered with a U-shaped cover 36' that fits into the opening.

With this configuration, this guide light has the following effects. That is, (1) the lamp 20 is arranged on the upper part of the lamp body 12, and the display board 26 is illuminated by reflection from the obliquely installed reflective plate 24, so that the display board 26 can be uniformly illuminated; Uniform brightness can be provided. As a result, it is possible to reduce the depth of the lamp body 12, occupying a smaller space, and eliminate the feeling of intimidation and foreign body when installed in an evacuation route. In this case, the light shielding plate 18a
This blocks direct light from the upper part of the display panel 26, further reducing uneven brightness. On the other hand, the lamp reflected light and the secondary reflected light from the display board 26 are transmitted through the opening 24e formed by the cut and raised piece 24d to illuminate the lower part of the guide light. Note that the lamp 20 may be provided on the side or bottom of the main body 12.

(2) Since the ballast 14 and lighting block 16 are attached to the support plate 13, the ballast 14 etc. can be assembled before attaching the support plate 13 to the lamp body 12, making it convenient to use a screwdriver etc. The ease of assembly is improved compared to the conventional method.

(3) A gap 21 is formed between the support plate 13 corresponding to the top plate and the upper edges 12f and 12g of the front surface 12a and rear surface 12b of the lamp body 12, respectively.
22, and by passing the upper end of the reflector 24 through this gap 21 from the side, a gap 2 is created between the lower end of the reflector 24 and the front surface 12a.
5 is formed and the display plate 26 is passed between the gaps 22 and 25. Therefore, compared to conventional caulking means, the display plate 26 can be easily and securely installed, and can be easily attached and detached, making maintenance easier. It becomes easier.

(4) By removing the cap 27 or 28 and pulling the display plate 26, the lamp can be easily replaced through the front opening 12d.

(5) Mounting holes 36c on top piece 36a and middle piece 36b
The cylindrical body 34 with a flange attached to the upper surface of the support plate 13 can be mounted on both a ceiling and a wall by the mounting main body 36 formed with a shape of 1. It can be easily installed by press-fitting in the horizontal direction as shown in Figures 12 to 14, and
Since it can be removed via the elastic ring 35 and rotated in a desired direction, it is easier to construct than conventional methods and can easily accommodate changes in the evacuation route. As a result, there is no need to form mounting holes in advance on the back of the main body, and problems such as light leakage due to these holes do not occur.

(6) Forming a battery storage recess 29 in the cap 28,
Since the battery 31 is housed in this and covered with the cover 30, it is extremely easy to replace the battery by attaching and detaching the cover 30, and it is also possible to prevent the influence of direct light from the lamp light, and furthermore, a heat dissipation hole is formed in the lamp body 12. There's no need. In particular, if the inner surface of the recess 29 is made of a heat insulating material, thermal effects on the battery 31 can be reliably prevented.

As described above, the indicator light of this invention has a reflector mounted on the top of the lamp by sliding it from the side and installing it diagonally, and also slides the display plate from the side and attaching it to the front of the reflector and the lamp. As a result, the depth of the lamp body can be reduced, and the display board can be mounted more easily and reliably than in the past, and can be easily attached and detached.
