Description

Technical Field

[0001] The present invention relates to an indicator light for displaying the position of a disaster prevention device such as a transmitter attached to an equipment storage box such as a fire hydrant box or a main control panel.

Background Art

[0002] As an example of an indicator light, for example, Patent Document 1 (Design Registration No. 1460558) discloses "an annular indicator light body made of a translucent member colored red and having a substantially rectangular opening for attaching a transmitter at the center, an annular attachment member that is detachably screwed to the indicator light body and is used to attach the indicator light body to a fire hydrant storage box or the like, and an annular substrate that is sandwiched and fixed between the indicator light body and the attachment member and has light-emitting diodes (LED lamps) attached at equal angles, and the light of the light-emitting diodes arranged in the annular space of the indicator light body is radiated annularly to the front and the surroundings" (description of the article related to the design in Patent Document 1).

[0003] In the above indicator light, the visibility can be improved by emitting light annularly, and since the transmitter can be attached to the central portion thereof, the area required for installation can be reduced as compared with a case where the indicator light and the transmitter are installed at separate positions.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The indicator lamp disclosed in Patent Document 1 attempts to improve visibility by arranging a large number of light-emitting diodes at equal intervals and causing an annular light-emitting display section to emit light. In conventional indicator lamps, including those disclosed in Patent Document 1, the main focus is on increasing the number of light-emitting diodes to increase the brightness (luminance) of the light-emitting display section in order to improve visibility. However, in the case of an indicator lamp with a thin annular light-emitting display section like the one described in Patent Document 1, simply increasing the luminance does not necessarily improve visibility. Also, since a large number of terminals are connected to fire protection equipment, there is a limit to the available current, and there is a current situation where it is difficult to increase the current flowing through the equipment. Due to such limitations, even if the number of light-emitting diodes in the indicator lamp is increased, the brightness of each LED only decreases, and visibility is not improved.

[0006] The present invention has been made to solve such problems, and an object thereof is to obtain an indicator lamp that can improve visibility without increasing the number or luminance of light sources in an indicator lamp with an annular light-emitting display section.

Means for Solving the Problems

[0007] (1-2) The indicator lamp according to the present invention is attached to a mounting surface and displays the position of disaster prevention equipment, It includes a main body portion having a transmitter housing portion that houses a substrate mounted with a light source and houses a transmitter having a push button, a push button storage portion, and a transmitter main body portion, and a light-emitting display portion that transmits the light emitted by the light source and is disposed on the outer peripheral side of the transmitter housed in the transmitter housing portion. The light source is disposed on the back side of the transmitter mounting surface portion in the transmitter housing portion so as to be hidden by the transmitter mounting surface portion, and the light-emitting display portion is configured such that indirect light of the light source is incident thereon. (1-1) The indicator lamp according to the present invention is an indicator lamp attached to a mounting surface and displays the position of disaster prevention equipment, It includes a main body portion that houses a substrate mounted with a light source and a light-emitting display portion that transmits the light emitted by the light source. The light-emitting display unit is formed in a ring shape, and has a transceiver housing unit that houses a transceiver having a push button, a push button storage unit, and a transceiver main body unit on the inner peripheral side of the ring-shaped light-emitting display unit when viewed from the front. In addition, a semi-transparent filler is filled in the space on the back side of the light-emitting display unit that houses the substrate so as to fill the space, and a reflector is attached so as to cover the transceiver attachment surface portion in the transceiver housing unit. (1) The indicating lamp according to the present invention is an indicating lamp that is attached to an attachment surface and indicates the position of a disaster prevention device, and has a main body unit that houses a substrate on which a light-emitting source is mounted, and a light-emitting display unit that transmits light emitted by the light-emitting source. The light-emitting display unit is formed in a ring shape, and a transceiver having a push button, a push button storage unit, and a transceiver main body unit is housed on the inner peripheral side of the ring-shaped light-emitting display unit when viewed from the front.

[0008] (2) Further, in the one described in (1) above, the front surface portion of the transceiver is positioned deeper than the light-emitting display unit.

[0009] (3) Further, in the one described in (1) or (2) above, the outer peripheral wall that forms the space for filling the filler is made light-tight.

[0010] (4) Further, in the one described in any one of (1) to (3) above, the arrangement and / or brightness of the light-emitting sources are set such that both side portions of the ring-shaped light-emitting display unit emit light brighter than the upper and lower portions.

[0011] (5) Further, in the one described in any one of (1) to (4) above, the light-emitting sources arranged on both sides are arranged closest to the light-emitting display unit among other light-emitting sources.

Advantages of the Invention

[0012] In the present invention, the light-emitting display portion is formed in a ring shape, and a transmitter is disposed on the inner peripheral side of the ring-shaped light-emitting display portion in a front view, and a substrate on which a light source is mounted is accommodated in a space on the back side of the light-emitting display portion. By filling the space with a translucent filler so as to fill the space, the light of the light source can be efficiently guided to the light-emitting display portion by the light guiding action of the translucent filler, causing the light-emitting display portion to emit light, and the visibility can be improved without increasing the number or brightness of the light sources.

Mode for Carrying Out the Invention

[0014] [Embodiment 1] In the present embodiment, an indicator light 1 that is attached to a wall surface 5 such as a housing of a fire hydrant facility as an attachment surface and houses a transmitter 3 (see FIGS. 6 and 7) will be taken as an example. And hereinafter, first, each configuration of the indicator light 1 will be described in detail with reference to FIGS. 1 to 5 and appropriately referring to other drawings, and then the transmitter 3 housed in the indicator light 1 will be described. In the following description, with the indicator light 1 attached to the wall surface 5, the front side of the wall surface 5 is referred to as the front, and the back side of the wall surface 5 is referred to as the back and the rear.

[0015] [Indicator Light] As shown in FIG. 1, the indicator light 1 includes an outer peripheral wall portion 7 formed of a substantially cylindrical body, a mounting portion 9 formed in a flange shape protruding outward from the outer peripheral surface on the front end side of the outer peripheral wall portion 7, a light-emitting display portion 11 formed in a ring shape inside the front end side of the outer peripheral wall portion 7, and a transmitter housing portion 13 formed inside the outer peripheral wall 7 continuously with the light-emitting display portion 11. And as shown in FIG. 3, a space portion 14 is formed between the outer peripheral wall portion 7 and the peripheral walls of the light-emitting display portion 11 and the transmitter housing portion 13 formed inside thereof, and a substrate 17 on which a light-emitting element 15 is mounted is installed in this space portion 14. Note that the outer peripheral wall portion 7, the light-emitting display portion 11, and the transmitter housing portion 13 in the present embodiment correspond to the main body portion of the present invention. Conversely, the main body portion of the present invention does not necessarily need to include all of these, and the shape is not limited as long as it has a function of housing a light source.

[0016] [Outer Peripheral Wall Portion] The outer peripheral wall portion 7 is formed in a substantially short cylindrical shape by a resin member having translucency.

[0017] [Mounting Portion] The attachment portion 9 is for attaching the display lamp 1 to the wall surface 5, and as described above, it is formed in a substantially square flange shape that projects outward from the outer peripheral surface on the front end side of the outer peripheral wall portion 7. As shown in FIGS. 1 and 2, screw holes 9a for attaching the display lamp 1 to the wall surface 5 are provided at the four corners of the attachment portion 9. The attachment portion 9 is provided with a ring-shaped standing piece portion 9b that frames the outer periphery of the light-emitting display portion 11. That is, a ring-shaped standing piece portion 9b is provided at the outer peripheral edge of the ring-shaped inclined surface that is the light-emitting display portion 11. When the display lamp 1 is attached to the wall surface 5, the standing piece portion 9b abuts against the edge of the opening provided in the wall surface 5 from the inside (see FIG. 3), and has a function of positioning (aligning) the display lamp 1.

[0018] <Light-emitting display portion> As shown in FIGS. 1 to 3, the light-emitting display portion 11 is formed in a ring shape that inclines inward and toward the back from the inner peripheral edge of the attachment portion 9. In FIG. 2, the light-emitting display portion 11 is colored for clarity. As shown in FIG. 3, the light-emitting display portion 11 does not protrude more than the wall surface 5 in the installed state of the display lamp 1, and it will not be damaged by an object hitting it from the side like a conventional general bulging type display lamp. The light-emitting display portion 11 is made of, for example, a red translucent member, and transmits the light from the light-emitting element 15 (see FIG. 3) housed in the space portion 14 to shine brightly. The arrangement relationship between the light-emitting display portion 11 and the light-emitting element 15 will be described later.

[0019] <Transmitter housing portion> As shown in FIGS. 1 and 3, the transmitter housing portion 13 is formed in a stepped shape inward and toward the back from the inner periphery of the light-emitting display portion 11, and the bottom of the step is the transmitter attachment surface portion 21 (see FIGS. 1 and 2) for attaching the transmitter 3.

[0020] The transmitter attachment surface portion 21 is composed of a flat surface made of a translucent member with a central opening, and screw holes 21a for attaching the transmitter 3 are provided on both sides. On the transmitter mounting surface portion 21, a reflector 25 is attached so as to cover the entire surface of the transmitter mounting surface portion 21. By attaching the reflector 25, the light of the light-emitting element 15 is reflected by the reflector 25 and further diffusely reflected by the surface of the substrate 17 or the like, and is emitted to the outside from the light-emitting display portion 11 as indirect light. In this way, by attaching the reflector 25, the light-emitting display portion 11 can be made to emit light with indirect light, and the light-emitting display portion 11 can be made to emit light brightly as a whole.

[0021] An example will be given for this point and will be described with reference to FIGS. 4 and 5. FIG. 4 shows a state in which the light-emitting element 15 is emitting light without attaching the reflector 25, and FIG. 5 shows a state in which the reflector 25 is attached to the one shown in FIG. 4. In FIG. 4, a portion where the light-emitting element 15 is located is shown in white. As shown in FIG. 4, since the light-emitting element 15 is disposed on the back side of the transmitter mounting surface portion 21, when the reflector 25 is not attached to the transmitter mounting surface portion 21, the light of the light-emitting element 15 passes through the transmitter mounting surface portion 21 without being reflected, and does not contribute to making the light-emitting display portion 11 emit light. On the other hand, when the reflector 25 is attached, as shown in FIG. 5, the light reflected by the reflector 25 enters the light-emitting display portion 11 as indirect light, and the light-emitting display portion 11 emits light brightly as a whole and the visibility is improved. As a result, even if the number of light-emitting elements 15 is small, the necessary visibility is ensured, and thus a power-saving effect is also obtained.

[0022] <Substrate> As shown in FIG. 1, the substrate 17 is formed by a disk with a central opening, and a plurality of light-emitting elements 15 as light sources are arranged on the front side of the substrate 17. As shown in FIG. 3, the substrate 17 is attached so that the front side faces the transmitter mounting surface portion 21. By attaching the substrate 17 in this way, the light-emitting element 15 is arranged so as to face the transmitter mounting surface portion 21 within the space portion 14 (see FIG. 2).

[0023] FIG. 2 is a front view of the indicator lamp 1 in a state where the substrate 17 is attached, and the light-emitting elements 15 on the substrate 17 are shown by dashed lines. The light-emitting elements 15 are arranged on the outer peripheral side, that is, the light-emitting elements 15 located at the positions closest to both the left and right ends of the substrate 17 are closer to the light-emitting display unit 11 than the other light-emitting elements 15 (see Fig. 2). In the example of Fig. 2, a part of the light-emitting elements 15 at both the left and right ends are arranged so as to cover the light-emitting display unit 11 in a front view. By arranging the light-emitting elements 15 in this way, both side portions of the light-emitting display unit 11 emit light more brightly than the upper and lower portions. And by creating a brightness difference between both side portions and the upper and lower portions, the visibility is enhanced compared to the case where the light-emitting display unit lights up with uniform brightness. Note that making both side portions of the light-emitting display unit 11 emit light more brightly than the upper and lower portions means that both side portions are relatively brighter than the upper and lower portions, and does not mean that both side portions are absolutely bright. Also, both side portions are a concept for distinguishing from the upper and lower portions and are not strictly defined in terms of area.

[0024] The transmitter 3 is to be provided at a certain height (80 to 150 cm from the floor surface), and the indicator lamp 1 provided integrally with the transmitter 3 is also provided at the same height. That is, the indicator lamp 1 is provided at a position close to the eye level of a person. When viewed from near the wall surface where the indicator lamp 1 is installed at such a height, that is, at a shallow angle, the light-emitting display unit 11 cannot be seen on the front side, but the back side can always be visually recognized (see Fig. 7). Therefore, by making both sides of the light-emitting display unit 11 emit light brightly, even when the indicator lamp 1 is viewed obliquely along the wall surface 5 with the indicator lamp 1 attached to the wall surface 5, there is an effect that the indicator lamp 1 can be surely visually recognized. Also, since both sides of the light-emitting display unit 11 emit light brightly, the upper and lower portions of the light-emitting display unit 11 become relatively dark, causing a change in the way the light-emitting display unit 11 emits light, which also improves the visibility.

[0025] 〔Transmitter〕 Next, the transmitter 3 housed in the transmitter housing portion 13 of the indicator lamp 1 described above will be described below with reference to Figs. 6 and 7. As shown in FIG. 6, the transmitter 3 has a push button 31 that transmits a fire signal when pressed, a push button storage portion 33 having a disk shape, and a transmitter main body portion 35 formed on the back side of the push button storage portion 33.

[0026] The push button storage portion 33 is provided with a telephone jack window door 33a that openably and closably covers a telephone jack (not shown) provided inside the push button storage portion 33 to which a handset is connected. The transmitter main body portion 35 has a box shape and stores a switch or the like (not shown) that interlocks with the push button 31 inside.

[0027] As shown in FIG. 7, when the transmitter 3 is housed in the transmitter housing portion 13 of the display lamp 1, it is arranged so as to be surrounded by the light emitting display portion 11 and to be substantially flush with the inner peripheral edge of the light emitting display portion 11. In this state, when the light emitting display portion 11 of the display lamp 1 lights up, the position of the transmitter 3 is displayed.

[0028] The effect in the usage state of the display lamp 1 configured as described above (the state in which the transmitter 3 is housed and the light emitting display portion 11 is lit) will be described with reference to FIG. 8. As shown in FIG. 8, the light emitting display portion 11 of the display lamp 1 normally shines brightly and displays the position of the transmitter 3 (disaster prevention device).

[0029] As described above, since both side portions of the light emitting display portion 11 shine brighter than the upper and lower portions, the display lamp 1 can be surely visually recognized even when viewed obliquely along the wall surface 5. Also, both sides of the light emitting display portion 11 are brighter than the upper and lower sides, and there is a change in the way the ring-shaped light emitting display portion 11 lights up. Therefore, when a person views the display lamp 1 while moving, as the position of the line of sight changes, the viewing angle of the display lamp 1 changes, and accordingly, the areas of both sides and the upper and lower surfaces of the light emitting display portion 11 that can be visually recognized change. As a result, the appearance of the display lamp 1 changes, and the visibility is further enhanced.

[0030] In addition, since the light-emitting display unit 11 has an inclined surface that faces the central portion, as shown in FIG. 2, it has excellent visibility from the front side and, as shown in FIG. 7, also has excellent visibility from the side. In addition, in this example, the transmitter 3 is installed inside the ring of the ring-shaped light-emitting display unit 11, and since it has the inclined surface as described above, the light-emitting display unit 11 can illuminate the push button 31 of the transmitter 3, and even in a dark place, the operation of the transmitter 3 and the connection work of the handset to the telephone jack are easy. In addition, the indicator light 1 does not have a large protruding portion from the wall surface 5, and it will not be damaged by being hit from the side like a conventional general bulging type indicator light 1.

[0031] In the above description, an example in which the light-emitting element 15 is arranged facing the front of the indicator light 1 as shown in FIG. 3 was shown, but the arrangement of the light-emitting element 15 is not limited to this. For example, as shown in FIG. 9, the light-emitting element 15 may be arranged facing the center of the indicator light 1, and by arranging it in this way, the visibility of the indicator light 1 from the side can be increased. In FIG. 9, the same components as those in FIG. 3 are denoted by the same reference numerals. Alternatively, an arrangement may be adopted in which a portion where the light-emitting element 15 is arranged facing the front side and a portion where the light-emitting element 15 is arranged facing the center of the indicator light 1 are mixed. However, in any case, as in the case shown in FIG. 3, the light-emitting elements 15 arranged on both sides are arranged so as to be closest to the light-emitting display unit 11 among the other light-emitting elements 15.

[0032] In the above description, an example in which the light-emitting elements 15 arranged on both sides are arranged so as to be closest to the light-emitting display unit 11 among the other light-emitting elements 15 in order to make both sides of the light-emitting display unit 11 glow brighter than the top and bottom was shown. However, as another method for making both sides of the light-emitting display unit 11 glow brighter than the top and bottom, for example, the distances from each light-emitting element 15 to the light-emitting display unit 11 may be made equal, and the brightness of the light-emitting elements 15 on both side portions may be set higher than those on the top and bottom portions. Alternatively, both the arrangement and the brightness of the light-emitting elements 15 may be adjusted. Furthermore, the light-emitting elements 15 may not be arranged vertically so that the upper and lower portions of the light-emitting display unit 11 become relatively dark. Further, a reflective material may be attached to the outer peripheral surface of the outer peripheral wall portion 7 so as to reflect light toward the inner periphery. By doing so, the light emitted from the light emitting element 15 and the light reflected by the reflective material do not pass through the outer peripheral wall portion 7 and escape to the back side of the wall surface 5, and the light emitting display portion 11 can emit light efficiently. Also, by attaching a reflective material to the upper and lower surfaces of the light emitting display portion 11, the light from the light emitting element 15 coming toward the upper and lower surfaces is also diffusely reflected, the upper and lower surfaces are not illuminated, and only both sides can be illuminated more strongly.

[0033] In addition, although an example of a circular ring is shown as the light emitting display portion 11, the light emitting display portion 11 of the present invention only needs to be ring-shaped and is not limited to a circular ring. For example, it may be rectangular ring-shaped or polygonal ring-shaped.

[0034] The light transmissive member constituting the light emitting display portion 11 is not limited to red. The light emitting display portion 11 may be composed of a colorless and transparent light transmissive member. In this case, by using a red LED as the light emitting element 15, the light emitting display portion 11 will be displayed in red.

[0035] In the above description, an example is shown in which the transmitter housing portion 13 is provided inside the ring of the light emitting display portion 11 and the transmitter 3 is housed. However, the transmitter 3 may be provided outside the indicator light 1. In this case, instead of the transmitter 3, a red disc covering the inside of the ring of the light emitting display portion 11 may be provided inside the ring of the light emitting display portion 11. As described above, the indicator light of the present invention can be configured as an indicator light 1 integrated with the transmitter 3, or can be configured as an indicator light separate from the transmitter 3, and these can be appropriately selected according to the situation.

[0036] [Embodiment 2] FIGS. 10 and 11 are explanatory views of an indicator light 37 according to Embodiment 2 of the present invention, and the same parts as those in Embodiment 1 are denoted by the same reference numerals. The indicating lamp 37 according to this embodiment has a main body 38 that houses a substrate 17 equipped with a light-emitting element 15 as a light source, and a light-emitting display section 11 that transmits and emits the light emitted by the light source, similar to the first embodiment. The light-emitting display section 11 is formed in a ring shape, and a transmitter 3 is arranged at a position surrounded by the ring-shaped light-emitting display section 11 (that is, on the inner peripheral side of the light-emitting display section 11 in a front view).

[0037] And in a space section 14 (refer to FIG. 11) where the substrate 17 on the back side of the light-emitting display section 11 is housed, a translucent filler 39 is filled so as to fill the space section 14 (refer to FIG. 10).

[0038] As the filler 39, for example, polyurethane, silicon, or the like can be used. In addition, the functions of the filler 39 include a waterproofing effect on the substrate 17, a function as a light guide that guides the light of the light-emitting element 15 to the light-emitting display section 11, and further, when light passes through the filler 39, the light spreads throughout the filler 39 and becomes like indirect light. In order to exhibit such a light diffusion function, the filler 39 needs to be translucent, and for example, a milky white one is preferable. Also, by covering the heat-generating light-emitting element 15 and the like with the filler 39, the heat generated is conducted to the filler 39, so the filler 39 also has a heat dissipation function.

[0039] Note that, as shown in FIG. 10, the front part of the transmitter 3 (the surface of the push button storage section 33) is located on the back side of the light-emitting display section 11. When the light-emitting element 15 is lit, the light-emitting display section 11 on the front side of the transmitter 3 lights up. Therefore, even when the indicating lamp 37 is viewed obliquely, the light-emitting display section 11 can be visually recognized without being blocked by the transmitter 3, and the light-emitting display section 11 can be reliably visually recognized. Also, when the indicating lamp 37 is viewed obliquely in a state where it is installed on the wall surface 5, the light-emitting display section 11 on the side opposite to the side where the viewer is located can be visually recognized. In this regard, in the device of Patent Document 1 (Design Registration No. 1460558), since the front surface of the transmitter arranged inside the ring-shaped indicating lamp main body protrudes, the visible appearance is different from that where only the side surface on the side where the viewer is located can be seen.

[0040] By filling the filler 39, the light of the light-emitting element 15 spreads throughout the filler 39. Therefore, the arrangement of the light-emitting element 15 does not necessarily have to be the same as that in the first embodiment. However, by adopting the same arrangement as in the first embodiment, as shown in the first embodiment, when a person views the display lamp 37 while moving, the appearance of the display lamp 37 changes, and the visibility can be improved.

[0041] Note that the light-emitting display unit 11 may be a vertical surface that hangs downward toward the back side instead of an inclined surface as in the first embodiment, as shown in FIG. 12. Even if the light-emitting display unit 11 is a vertical surface that is not inclined, as shown in FIG. 12, with the transmitter 3 housed, the depth of the vertical surface is set to be deeper than the thickness of the push-button storage unit 33 of the transmitter 3, so that the front surface of the push-button storage unit 33 of the transmitter 3 is arranged on the back side of the light-emitting display unit 11 and the upper part of the vertical surface is exposed. Therefore, when the light-emitting element 15 is lit, the vertical surface emits light, and the light-emitting display unit 11 can be visually recognized without being blocked by the transmitter 3 even when the display lamp 37 is viewed obliquely, and the light-emitting display unit 11 can be reliably visually recognized. In addition, by making the light-emitting display unit 11 a vertical surface that hangs downward toward the back side, there is also an effect that the ring-shaped light-emitting display unit 11 does not spread radially outward of the ring diameter, and the overall shape can be made compact.

[0042] As described in the first embodiment, for example, a reflective material may be attached to the outer peripheral surface of the outer peripheral wall portion 7 to make the outer peripheral wall portion 7 light-tight, so that the light is reflected to the inner peripheral side. Thereby, the light emitted from the light-emitting element 15 does not pass through the outer peripheral wall portion 7 and escape to the back side of the wall surface 5, and the light-emitting display unit 11 can emit light efficiently. Note that, as a means for making the outer peripheral wall portion 7 light-tight, in addition to attaching a reflective material, the outer peripheral wall portion 7 may be covered with a light-tight and highly reflective cover body. The cover body is formed of, for example, white resin.
