Description

【Technical Field】 【0001】 The present invention relates to an indicator light for indicating 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 switchboard. 【Background Art】 【0002】 As an example of an indicator light, for example, in Patent Document 1 (Design Registration No. 1460558), "an annular indicator light body made of a translucent member colored red and having a substantially rectangular opening for attaching a transmitter in the central portion, an annular attachment member detachably screwed to the indicator light body for attaching the indicator light body to a fire hydrant storage box or the like, and an annular substrate sandwiched and fixed between the indicator light body and the attachment member and having 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 periphery" (description of the article according to the design in Patent Document 1) is disclosed. 【0003】 In the above indicator light, visibility can be improved by emitting light annularly, and since a 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. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Design Registration No. 1460558 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 The indicator light disclosed in Patent Document 1 attempts to improve visibility by arranging a large number of light-emitting diodes at equal intervals to illuminate a ring-shaped light-emitting display section. Conventional indicator lights, including the one disclosed in Patent Document 1, primarily focus on increasing the brightness (luminance) of the light-emitting display section by increasing the number of light-emitting diodes in order to improve visibility. However, in the case of indicator lights with a thin, ring-shaped light-emitting display section, such as the one described in Patent Document 1, simply increasing the brightness does not necessarily improve visibility. Furthermore, because fire safety equipment has many terminals connected, there is a limit to the available current, and it is currently difficult to increase the current flowing through the equipment. Due to these limitations, increasing the number of light-emitting diodes in an indicator light only reduces the brightness of each LED, and does not improve visibility. 【0006】 This invention was made to solve the aforementioned problems, and aims to provide an indicator light that can improve visibility without increasing the number or brightness of light sources, in a circular light-emitting display unit. [Means for solving the problem] 【0007】 (1-2) The indicator light according to the present invention is mounted on a mounting surface to indicate the location of disaster prevention equipment, The device comprises a main body that houses a circuit board equipped with a light source and a transmitter housing that houses a transmitter having a push button, a push button storage section, and a transmitter body, and a light-emitting display section that emits light through the light source and is located on the outer circumference of the transmitter housed in the transmitter housing, The light source is positioned on the rear side of the transmitter mounting surface in the transmitter housing section so as to be hidden by the transmitter mounting surface, and the light-emitting display section is configured to receive indirect light from the light source. (1-1) The indicator light according to the present invention is an indicator light that is mounted on a mounting surface to indicate the location of disaster prevention equipment, It has a main body that houses a substrate equipped with a light source, and a light-emitting display section that transmits the light emitted by the light source, The light-emitting display unit is formed in a ring shape, and in a front view, the inner circumference of the ring-shaped light-emitting display unit has a transmitter housing unit that houses a transmitter having a push button, a push button storage unit, and a transmitter body. Furthermore, the present invention is characterized in that a translucent filler material is filled into the space on the back side of the light-emitting display section in which the substrate is housed, and a reflector is attached to cover the transmitter mounting surface in the transmitter housing section. (1) The indicator light according to the present invention is an indicator light that is mounted on a mounting surface to indicate the location of disaster prevention equipment, and comprises a main body that houses a substrate equipped with a light source, and a light-emitting display section that transmits light emitted by the light source, wherein the light-emitting display section is formed in a ring shape, and a transmitter having a push button, a push button storage section, and a transmitter body is housed on the inner circumference side of the ring-shaped light-emitting display section in a front view, Furthermore, the present invention is characterized in that a translucent filler material is filled into the space on the back side of the light-emitting display unit in which the substrate is housed, so as to fill the space. 【0008】 (2) Furthermore, in the case described in (1) above, the front part of the transmitter is located further back than the light-emitting display part. 【0009】 (3) Furthermore, in the case described in (1) or (2) above, the outer peripheral wall forming the space in which the filler material is filled is made opaque. 【0010】 (4) In addition, in any of the above (1) to (3), the light-emitting display unit is characterized in that the arrangement of the light source and / or brightness are set such that the sides of the ring shine brighter than the top and bottom. 【0011】 (5) In addition, in any of the above (1) to (4), the light sources arranged on both sides are characterized in that they are positioned closest to the light-emitting display section than the other light sources. [Effects 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. Further, a semi-transparent filler is filled in the space on the back side of the light-emitting display portion that houses the substrate on which the light source is mounted so as to fill the space. Due to the light-guiding action of the semi-transparent filler, the light of the light source can be efficiently guided to the light-emitting display portion to cause the light-emitting display portion to emit light, and the visibility can be improved without increasing the number or brightness of the light sources. 【Brief Description of the Drawings】 【0013】 [Figure 1] It is an exploded perspective view of a display lamp according to an embodiment of the present invention.

And hereinafter, first, each component of the indicating lamp 1 will be described in detail with reference to FIGS. 1 to 5 as appropriate while referring to other drawings, and then the transmitter 3 housed in the indicating lamp 1 will be described. In the following description, with the indicating lamp 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】 [Indicating Lamp] As shown in FIG. 1, the indicating lamp 1 includes an outer peripheral wall portion 7 formed of a substantially cylindrical body, a mounting portion 9 formed in a flange shape that projects 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 mounting portion 9 is for attaching the indicator light 1 to the wall surface 5, and as described above, it is formed in the shape of a roughly square flange that protrudes outward from the outer peripheral surface on the front end side of the outer peripheral wall portion 7. As shown in Figures 1 and 2, screw holes 9a are provided at the four corners of the mounting portion 9 for attaching the indicator light 1 to the wall surface 5. The mounting portion 9 is provided with a ring-shaped vertical piece 9b that borders the outer circumference of the light-emitting display portion 11. In other words, the ring-shaped vertical piece 9b is provided on the outer edge of the ring-shaped inclined surface that is the light-emitting display portion 11. When the indicator light 1 is mounted on the wall surface 5, the vertical piece 9b abuts against the edge of the opening provided in the wall surface 5 from the inside (see Figure 3), and has the function of positioning (aligning) the indicator light 1. 【0018】 <Light-emitting display section> As shown in Figures 1 to 3, the light-emitting display unit 11 is formed in a ring shape that slopes inward and toward the back from the inner peripheral edge of the mounting unit 9. In Figure 2, the light-emitting display unit 11 is colored to clearly show it. As shown in Figure 3, the light-emitting display unit 11 does not protrude significantly beyond the wall surface 5 when the indicator light 1 is installed, so that it is not susceptible to damage from objects hitting it from the side, unlike conventional bulging-type indicator lights. The light-emitting display unit 11 is made of, for example, a red translucent material and is designed to emit bright light by allowing light from the light-emitting element 15 (see Figure 3) housed in the space 14 to pass through. The arrangement of the light-emitting display unit 11 and the light-emitting element 15 will be described later. 【0019】 <Transmitter housing> As shown in Figures 1 and 3, the transmitter housing section 13 is formed in a stepped shape on the inner and rearward side from the inner circumference of the light-emitting display section 11, and the bottom of the step is the transmitter mounting surface section 21 (see Figures 1 and 2) for attaching the transmitter 3. 【0020】 The transmitter mounting surface 21 is made of a translucent material and has a flat surface with an opening in the center, and screw holes 21a for attaching the transmitter 3 are provided on both sides. A reflector 25 is attached to the transmitter mounting surface 21 so as to cover the entire surface of the transmitter mounting surface 21. By attaching the reflector 25, the light from the light-emitting element 15 is reflected by the reflector 25 and further diffusely reflected by the surface of the substrate 17, etc., and emitted to the outside from the light-emitting display unit 11 as indirect light. In this way, by attaching the reflector 25, the light-emitting display unit 11 can be illuminated with indirect light, and the light-emitting display unit 11 can be illuminated brightly overall. 【0021】 This point will be explained with examples, based on Figures 4 and 5. Figure 4 shows the state in which the light-emitting element 15 is illuminated without the reflector 25 attached, and Figure 5 shows the state in which the reflector 25 is attached to the same structure as in Figure 4. In Figure 4, the area where the light-emitting element 15 is located is shown in white. As shown in Figure 4, since the light-emitting element 15 is positioned on the back side of the transmitter mounting surface 21, if the reflector 25 is not attached to the transmitter mounting surface 21, the light from the light-emitting element 15 will pass through the transmitter mounting surface 21 without being reflected and will not contribute to illuminating the light-emitting display unit 11. On the other hand, when the reflector 25 is attached, as shown in Figure 5, the light reflected by the reflector 25 enters the light-emitting display unit 11 as indirect light, causing the light-emitting display unit 11 to light up brightly overall and improving visibility. As a result, the necessary visibility can be ensured even with a small number of light-emitting elements 15, thus achieving power saving effects. 【0022】 <Circuit board> As shown in Figure 1, the substrate 17 is formed by a circular disc with an open center, and multiple light-emitting elements 15 are arranged on the front side of the substrate 17 to serve as light sources. As shown in Figure 3, the circuit board 17 is mounted so that its front side faces the transmitter mounting surface 21. With the substrate 17 attached in this manner, the light-emitting element 15 is positioned within the space 14 so as to face the transmitter mounting surface 21 (see Figure 2). 【0023】 Figure 2 is a front view of the indicator light 1 with the circuit board 17 attached, and the light-emitting element 15 on the circuit board 17 is shown by a dashed line. The light-emitting elements 15 are arranged on the outer periphery of the substrate 17 such that the light-emitting elements 15 closest to the left and right ends are closest to the light-emitting display unit 11 than the other light-emitting elements 15 (see Figure 2). In the example in Figure 2, the light-emitting elements 15 at both the left and right ends are arranged so that a portion of them overlaps the light-emitting display unit 11 when viewed from the front. With the light-emitting elements 15 arranged in this manner, the sides of the light-emitting display unit 11 shine brighter than the top and bottom. This difference in brightness between the sides and the top and bottom improves visibility compared to when the light-emitting display unit illuminates at a uniform brightness. Furthermore, stating that the sides of the light-emitting display section 11 are brighter than the top and bottom means that the sides are relatively brighter than the top and bottom, and does not mean that the sides are absolutely brighter. Also, the term "sides" is a concept used to distinguish them from the top and bottom, and does not refer to a strictly defined area. 【0024】 The transmitter 3 is to be installed at a certain height (80-150 cm from the floor), and the indicator light 1, which is installed integrally with the transmitter 3, is also installed at the same height. In other words, the indicator light 1 is installed at a position close to a person's eye level. When the indicator light 1 is viewed from near the wall where it is installed at such a height, that is, at a shallow angle, the front side of the light-emitting display unit 11 is not visible, but the back side is always visible (see Figure 7). Therefore, by illuminating both sides of the light-emitting display unit 11 brightly, the indicator light 1 can be reliably seen even when the indicator light 1 is mounted on the wall 5 and viewed from an oblique angle along the wall 5. Furthermore, because both sides of the light-emitting display unit 11 light up brightly, the areas above and below the light-emitting display unit 11 become relatively darker, resulting in a change in the way the light-emitting display unit 11 illuminates, which also improves visibility. 【0025】 [Transmitter] Next, the transmitter 3 housed in the transmitter housing section 13 of the indicator light 1 described above will be explained below with reference to Figures 6 and 7. As shown in Figure 6, the transmitter 3 includes a push button 31 that emits a fire signal when pressed, a disc-shaped push button storage section 33, and a transmitter body section 35 formed on the back side of the push button storage section 33. 【0026】 The push-button storage section 33 is provided with a telephone jack window door 33a that can be opened and closed to cover a telephone jack (not shown) located inside the push-button storage section 33 to which a handset is connected. The transmitter unit 35 is box-shaped and houses switches (not shown) that are linked to the push button 31. 【0027】 As shown in Figure 7, when the transmitter 3 is housed in the transmitter housing 13 of the indicator light 1, it is positioned so as to be surrounded by the light-emitting display unit 11 and so as to be substantially flush with the inner periphery of the light-emitting display unit 11. In this state, the position of the transmitter 3 is indicated when the light-emitting display unit 11 of the indicator light 1 lights up. 【0028】 The effects of the indicator light 1 in the configuration described above (with the transmitter 3 housed and the light-emitting display unit 11 illuminated) will be explained with reference to Figure 8. As shown in Figure 8, the light-emitting display unit 11 of the indicator light 1 is normally brightly lit and indicates the location of the transmitter 3 (disaster prevention equipment). 【0029】 As mentioned above, the sides of the light-emitting display unit 11 shine brighter than the top and bottom, so the indicator light 1 can be clearly seen even when viewed from an oblique angle along the wall surface 5. In addition, since the sides of the light-emitting display unit 11 are brighter than the top and bottom, and the way the ring-shaped light-emitting display unit 11 shines changes, when a person looks at the indicator light 1 while moving, the angle at which they view the indicator light 1 changes as their line of sight changes, and consequently, the visible area of ​​both sides and the top and bottom surfaces of the light-emitting display unit 11 changes. As a result, the appearance of the indicator light 1 changes, and its visibility is further improved. 【0030】 Furthermore, since the light-emitting display section 11 has a sloping surface toward the center, it offers excellent visibility from the front, as shown in Figure 2, and also excellent visibility from the side, as shown in Figure 7. Furthermore, in this example, the transmitter 3 is installed inside the ring of the ring-shaped light-emitting display unit 11, and because of the inclined surface as described above, the light-emitting display unit 11 can illuminate the push button 31 of the transmitter 3, making it easy to operate the transmitter 3 and connect the handset to the telephone jack even in the dark. Furthermore, the indicator light 1 does not have any parts that protrude significantly from the wall surface 5, so it is not susceptible to damage from objects hitting it from the side, unlike conventional, typical bulging indicator lights 1. 【0031】 In the above explanation, an example was shown in which the light-emitting element 15 is positioned facing the front of the indicator light 1, as shown in Figure 3. However, the positioning of the light-emitting element 15 is not limited to this. For example, as shown in Figure 9, the light-emitting element 15 may be positioned facing the center of the indicator light 1. By positioning it in this way, the visibility of the indicator light 1 from the side can be increased. In Figure 9, the same reference numerals are used for components that are the same as those in Figure 3. Alternatively, the arrangement may include a mix of light-emitting elements 15 facing forward and those facing towards the center of the indicator light 1. However, in either case, as in the case shown in Figure 3, the light-emitting elements 15 on both sides are arranged to be closest to the light-emitting display unit 11 than the other light-emitting elements 15. 【0032】 Furthermore, in the above explanation, an example was shown in which the light-emitting elements 15 placed on both sides are positioned closest to the light-emitting display unit 11 than the other light-emitting elements 15 in order to make both sides of the light-emitting display unit 11 light up brighter than the top and bottom. However, as another method for making both sides of the light-emitting display unit 11 light up brighter than the top and bottom, for example, the distance of 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 sides may be set higher than that of the top and bottom. Alternatively, both the arrangement and brightness of the light-emitting elements 15 may be adjusted. Furthermore, the light-emitting elements 15 may not be placed at the top and bottom so that the upper and lower parts of the light-emitting display unit 11 become relatively darker. Furthermore, a reflective material may be attached to the outer surface of the outer wall portion 7 so as to reflect light towards the inner side. By doing so, the light emitted from the light-emitting element 15 and the light reflected by the reflective material will not pass through the outer wall portion 7 and escape to the back side of the wall surface 5, allowing the light-emitting display portion 11 to emit light efficiently. Furthermore, by attaching reflective material to the upper and lower surfaces of the light-emitting display unit 11, the light from the light-emitting element 15 directed towards the upper and lower surfaces is also diffusely reflected, so that the upper and lower surfaces do not light up, and only the sides light up more brightly. 【0033】 Furthermore, although a circular ring was shown as an example for the light-emitting display unit 11, the light-emitting display unit 11 of the present invention is not limited to a circular ring and can be any ring shape, such as a rectangular ring or a polygonal ring. 【0034】 The translucent material constituting the light-emitting display unit 11 is not limited to red. The light-emitting display unit 11 may be made of a colorless, transparent translucent material. In this case, by using a red LED for the light-emitting element 15, the light-emitting display unit 11 will display in red. 【0035】 Furthermore, although the above description shows an example in which the transmitter 3 is housed in a transmitter housing 13 inside the ring of the light-emitting display unit 11, the transmitter 3 may be provided outside the indicator light 1. In this case, instead of the transmitter 3, a red disc that covers the inside of the ring of the light-emitting display unit 11 may be provided inside the ring of the light-emitting display unit 11. Thus, the indicator light of the present invention can be configured as an indicator light 1 integrated with the transmitter 3, or as a separate indicator light from the transmitter 3, and these can be appropriately selected depending on the situation. 【0036】 [Embodiment 2] Figures 10 and 11 are explanatory diagrams of the indicator light 37 of Embodiment 2 of the present invention, and the same parts as in Embodiment 1 are denoted by the same reference numerals. The indicator light 37 according to this embodiment, similar to Embodiment 1, has a main body 38 that houses a substrate 17 on which a light-emitting element 15 is mounted as a light source, and a light-emitting display section 11 that shines by allowing light emitted from the light source to pass through. The light-emitting display section 11 is formed in a ring shape, and the transmitter 3 is positioned in the area surrounded by the ring-shaped light-emitting display section 11 (i.e., on the inner circumference side of the light-emitting display section 11 in a front view). 【0037】 Furthermore, the space 14 (see Figure 11) in which the substrate 17 on the back side of the light-emitting display unit 11 is housed is filled with a translucent filler material 39 to fill the space 14 (see Figure 10). 【0038】 For example, polyurethane or silicone can be used as the filler material 39. The functions of the filler material 39 include waterproofing the substrate 17, acting as a light guide to direct the light from the light-emitting element 15 to the light-emitting display unit 11, and allowing light to spread throughout the filler material 39 as it passes through, resulting in indirect lighting. In order to exhibit such light diffusion functions, the filler material 39 needs to be semi-transparent, and for example, an opaque white material is preferred. Furthermore, by covering the heat-generating light-emitting element 15, etc., with the filler 39, the heat generated is conducted to the filler 39, so the filler 39 also has a heat dissipation effect. 【0039】 Furthermore, as shown in Figure 10, the front of the transmitter 3 (the surface of the push-button storage section 33) is positioned behind the light-emitting display section 11. When the light-emitting element 15 lights up, the light-emitting display section 11, which is in front of the transmitter 3, lights up. Therefore, even when viewing the indicator light 37 from an oblique angle, the light-emitting display section 11 can be seen without being obstructed by the transmitter 3, ensuring that the light-emitting display section 11 is clearly visible. Furthermore, when the indicator light 37 is viewed from an angle while installed on the wall 5, the light-emitting display unit 11 on the opposite side from the viewer can be seen. In this respect, the appearance differs from that of the device described in Patent Document 1 (Design Registration No. 1460558), where the front of the transmitter, which is positioned inside the ring, protrudes more than the ring-shaped indicator light body, so only the side on the viewer's side is visible. 【0040】 By filling with the filler material 39, the light from the light-emitting element 15 spreads throughout the filler material 39. Therefore, the arrangement of the light-emitting element 15 does not necessarily have to be the same as in Embodiment 1. However, by arranging it in the same way as in Embodiment 1, as shown in Embodiment 1, when a person looks at the indicator light 37 while moving, the appearance of the indicator light 37 changes, resulting in improved visibility. 【0041】 Furthermore, the light-emitting display unit 11 may not be an inclined surface as in Embodiment 1, but rather a hanging surface that slopes downward toward the back, as shown in Figure 12. Even if the light-emitting display unit 11 has a non-sloping downward surface, as shown in Figure 12, by setting the depth of the downward surface to be greater than the thickness of the push-button storage section 33 of the transmitter 3 when the transmitter 3 is housed, the front of the push-button storage section 33 of the transmitter 3 is positioned further back than the light-emitting display unit 11, and the upper part of the downward surface is exposed. As a result, when the light-emitting element 15 lights up, the downward surface illuminates, and the light-emitting display unit 11 can be seen without being obstructed by the transmitter 3 even when the indicator light 37 is viewed from an angle, ensuring that the light-emitting display unit 11 is clearly visible. Furthermore, by making the light-emitting display section 11 a hanging surface that hangs down towards the back, the ring-shaped light-emitting display section 11 does not spread outward in the ring diameter direction, which has the effect of making the overall shape more compact. 【0042】 As explained in Embodiment 1, the outer surface of the outer wall portion 7 may be made opaque by, for example, attaching a reflective material to it, thereby reflecting light to the inner side. This prevents the light emitted from the light-emitting element 15 from passing through the outer wall portion 7 to the back of the wall surface 5, allowing the light-emitting display portion 11 to emit light efficiently. In addition to attaching a reflective material, the outer perimeter wall 7 may also be covered with a cover that is opaque and highly reflective. This cover may be made of, for example, a white resin.
