However, many of the conventional speaker-integrated warning lights, such as the rotation warning light disclosed in Patent Document 1, have a speaker provided at a lower portion of the main body. For this reason, the generation direction of the speaker provided in the lower part of the main body is limited, and it has not been possible to efficiently raise the notification sound to the front (normal line) side of the mounting surface.
On the other hand, when a horizontally long globe is used as in the warning light disclosed in Patent Document 2, the shape of the globe makes it impossible to efficiently spread the notification light from the surrounding area. As shown in Design Registration No. 1390864, even though a speaker may be mounted on the top of a horizontally long glove, many of its forms are incorporated by separating the horizontally long glove into right and left. Was. For this reason, it is difficult to efficiently spread the notification sound to the front (normal line) side of the mounting surface or its surroundings and efficiently spread the notification light from the surroundings due to the arrangement of the speaker and the light emitting unit. Met.

  In addition, if the speaker is to be integrally mounted on the center of the globe in the globe informing light of Patent Literature 1 that gives a rotation warning to the surroundings, if a speaker is to be integrally mounted, a speaker hole is provided in the speaker mounting portion for increasing the notification sound. It needs to be provided. For this reason, when installed outdoors, there was a problem that the light emitting part would break down due to flooding into the glove through this hole.

  In view of the above, the present invention has a compact configuration in which a speaker and a notification lamp are integrated at the upper part, so that the notification sound can be efficiently amplified to the front (normal line) side of the mounting surface or around the mounting surface, and the notification light can be emitted. It is an object of the present invention to provide an information lamp that can efficiently spread light from its surroundings and that is excellent in water stoppage.

  In view of the above problems, the present invention takes the following measures. However, in the following, the numerals and alphabets described following the names of the components are reference numerals for convenience of understanding of the drawings, and do not limit the concept, shape, or structure of the components.

(1) The notification light according to the present invention is:
A main body 1 comprising a short cylindrical body having a lower surface as a mounting surface, and a light emitting device including a prism light emitting body 13 and a light emitting element on an upper portion thereof;
A dome-shaped glove 2 attached over the upper part of the main body 1;
A lid-shaped loudspeaker plate 3 attached over a central hole 20 formed at the center of the top of the glove 2;
A waterproof speaker 4 that is attached to the inside of the globe 2 so as to cover below the central hole 20 of the globe 2,
The waterproof speaker 4 has, in a continuous waterproof structure, a cylindrical frame opened upward and a diaphragm attached so as to cover the inside of the column from around the upper part of the frame, and has an annular stopper around the upper part of the frame. Water material 4G is locked,
An annular water-stopping material 4G around the upper part of the frame is pressed against the center hole 20 of the globe 2 to form a water-stopping structure.

  That is, by combining the loudspeaker plate, the packing as the water-stopping material, and the waterproof speaker in close contact with the central top of the dome-shaped globe, an information lamp having a compact overall shape and excellent in water stoppage can be formed.

(2) In the notification lamp, the waterproof speaker 4 has a flange-shaped overhang formed integrally around the upper part of the frame, and has a connection portion at a part of the lower surface of the overhang. It is preferable to further include a short annular fixing tool 5 which is in contact with the overhanging portion and is pressure-fixed to the inner surface of the top of the glove.
According to the above structure, the waterproof speaker is hung in a press-fit state on the inner surface of the glove by closing the center hole of the glove, and the waterproof material 4G is interposed between the upper surface of the overhang portion and the inner surface of the glove. Makes a reliable waterproof structure. Further, the speaker is connected to the lower surface of the overhang portion, and the connection portion is crimped with the fixture 5, so that disconnection can be prevented while keeping the connection portion waterproof.

  (3) In the alarm lamp, the loudspeaker plate 3 is formed of a circular plate or a polygonal plate having a plurality of upstanding legs, has a concave depression 30 in the center of the plate, and has many small holes in the depression 30. Preferably, a hole 3H is formed. The notification sound is efficiently loudspeaked by the upper surface depression and the perforated hole of the central loudspeaker plate.

Further, a rectangular second recess 301 whose upper surface is further recessed is formed in the central portion of the recess 30 of the sound enhancement plate 3, and a side opening opened laterally between the plurality of standing legs. 320 are formed.
A part of the central hollow portion 30 of the loudspeaker plate 3 is formed by a thin plate by the rectangular second hollow 301, and the notification sound from the central hole 20 of the globe 2 can be diffusely reflected at the thin plate portion. In addition, by generating the irregularly reflected notification sound from the plurality of side openings 320 to the outside, the notification sound can be emitted in a state where the notification sound is amplified around the dome shape. Moreover, the glove 2 is provided with a heat radiating function by the plurality of small holes 3H and the side openings 320. In the case where the loudspeaker plate 3 is made of a conductive material such as aluminum metal, the loudspeaker plate 3 further has a heat dissipation function.

  That is, since the sound-enhancing plate 3 is formed of a circular plate or a polygonal plate having a plurality of upright legs and a concave recess 30 at the center of the plate, not only the waterproofing of the central hole but also the central hole 20 is achieved. It will be a signal light with a sound release and heat dissipation function.

  (4) In the notification lamp, the main body 1 has a notification light emitting substrate 12 provided with a diffusion prism and a light emitting element on an upper portion of the short cylinder, and emits light of the light emitting element inside the short cylinder. It is preferable to have a control board 11 for controlling the notification sound of the waterproof speaker, and to constitute a light emitting device which is double separated from the light emitting board and the control board.

  The control substrate 11 which does not heat is accommodated in the short cylinder below the light emitting substrate 12 which becomes relatively hot during operation, so that the light emitting device is constituted by vertically separated double separated substrates. By providing a heat-generating substrate at the upper part that is open inside the glove and separating it from the non-heat-generating substrate, the upper part has a structure in which heat is easily discharged to the glove side during operation and is less likely to be flooded inside. On the upper surface of the light-emitting substrate 12, a plurality of light-emitting elements wired to each other are arranged at a distance around the center of the board, and a transparent triangular prism body is radially combined so as to cover the light-emitting element. A diffusion prism 13 composed of an upwardly convex solid body is attached. Thus, even if the light emitting substrate 12 is flooded, it is possible to suppress further downward flooding. In other words, even if the light-emitting portion is flooded, the diffusion prism 13 covers most of the upper surface of the light-emitting substrate 12, so that flooding below the substrate can be prevented. On the other hand, the triangular prism of the diffusion prism 13 can provide a prism diffusion effect of diffusing light of the light emitting element around a predetermined direction in the globe.

(5) In the notification lamp, the main body 1 is provided with three- or four-sided fitting frames 161 and 162 in the lower frame 15 at the lower portion of the short cylindrical body, and a box-like shape fitted into the fitting frame. It is preferable to have a mounting structure including a fixing screw 62B for fixing the mounting plate fitted into the fitting frame.
In this mounting structure, a lower space 150 is formed between the periphery of the mounting plate 6 and the lower frame 15. Furthermore, it is preferable that a part of the mounting plate or the fitting frame is provided with a locking structure for locking corresponding portions of the fitted mounting plate or the fitting frame to each other.

  That is, the mounting structure in which the mounting plate 6 which is slightly smaller than the bottom shape of the lower frame 15 of the main body 1 is fitted does not have an angle part for mounting or a member which protrudes or protrudes from a wall surface or a ceiling surface. For this reason, the integrated information light of the present invention can be mounted in a good shape along the mounting surface. Also, instead of the mounting plate 6 being provided entirely in the lower frame, a plurality of lower spaces 150 each formed of a partial circle surrounded by a chord and an arc are formed between the lower frame and the mounting plate 6. By the formation of the lower frame 15 and the lower space 150, a space for preventing water or infiltration is secured between the lower frame 15 and the mounting surface, and the mounting surface has an excellent waterproof function.

  According to the present invention, by taking the above-mentioned means, the speaker and the notification lamp are integrated into a compact structure at the upper part, so that the notification sound can be efficiently propagated to the front (normal) side of the mounting surface or the periphery thereof. In addition, the notification light can be efficiently spread from its surroundings. Further, it is possible to form an information lamp which is excellent in water stoppage while having a compact configuration in which the speaker and the notification lamp are integrated at the upper part.
