[Patent Document 1] Japanese Design Patent Registration No. 1460558

The display lamp disclosed in Patent Document 1 is configured by arranging a plurality of light-emitting diodes at equal intervals to make the ring-shaped light-emitting display section emit light to improve visual recognition. Including those disclosed in Patent Document 1, in order to improve the visibility of conventional display lamps, the emphasis is on increasing the number of light-emitting diodes and enhancing the brightness (brightness) of the light-emitting display portion.

However, as in the display lamp described in Patent Document 1, in the case where the light-emitting display portion is a thin circular ring shape, merely increasing the brightness does not necessarily improve the visibility. In addition, since there are many terminal devices connected to the fire fighting equipment, there is a situation where it is difficult to increase the current flowing to the equipment due to the limitation of the usable current. Due to the above limitations, even if the number of light-emitting diodes of the display lamp is increased, the brightness of each LED is only reduced, and visual recognition cannot be improved.

The present invention was developed to solve this problem, and its purpose is to achieve a visual recognition ability that does not increase the number of light sources or the brightness of the light-emitting display portion in the shape of a ring Indicator.

The inventor is not just about increasing the brightness but about whether or not The visual recognition can be improved for review. In the case of, for example, a lamp flickering, the visual recognition is improved, and the light-emitting display portion is given a change. In other words, the visual appearance is considered to be changed by giving a change to the appearance of the light-emitting display portion. Increased recognition.

The present invention has been completed based on this knowledge, and specifically has the following structure.

(1) The display lamp of the present invention is a display lamp mounted on an installation surface and showing the position of a disaster prevention device, and has a body portion that houses a light-emitting source, and a light-emitting display portion that transmits light emitted by the light-emitting source and emits light. The light-emitting display portion is formed in a ring shape, and the arrangement of the light-emitting source and/or the brightness setting are performed so that both side portions emit light brighter than the upper and lower portions.

(2) Furthermore, in the one described in (1) above, the light-emitting sources arranged on both sides are arranged closer to the light-emitting display section than other light-emitting sources.

(3) Furthermore, in the one described in (1) or (2) above, the light-emitting display unit is configured so that light is incident between the light-emitting sources.

(4) Furthermore, in the one described in (1) or (2) above, the light-emitting display unit includes an inclined surface inclined toward the inner side of the ring and the back side, and the inclined surface in the light-emitting display unit is provided It will not protrude from the aforementioned mounting surface.

(5) Furthermore, in the person described in (3) above, the aforementioned light emission The display unit includes an inclined surface inclined toward the inner side of the ring and the back side. The inclined surface in the light-emitting display unit is provided so as not to protrude from the mounting surface.

According to the present invention, the light-emitting display portion is formed in a ring shape, and the arrangement of the light-emitting source and/or the brightness setting are performed in such a manner that both side portions emit light brighter than the upper and lower portions, thereby also along the mounting surface When viewing the display light on the inclined surface, the display light can be reliably visually recognized. In addition, since the light-emitting display unit emits light more brightly on both sides than above and below, the light-emitting mode of the ring-shaped light-emitting display unit changes, so when a person looks at the display lamp while moving, the position of the line of sight changes, causing the viewing The angle of the display lamp changes. Along with this, the areas on both sides and the top and bottom of the light-recognizable light-emitting display part will change. Therefore, the viewing method of the display lamp will change, which will improve the visual recognition.

In the present embodiment, a series of display lamps 1 mounted on a wall surface 5 of a frame or the like of a hydrant device as an installation surface, and accommodating a transmitter 3 (refer to FIGS. 6 and 7) are included.

In the following, first, each configuration of the indicator lamp 1 will be described in detail based on FIGS. 1 to 5 with appropriate reference to other figures, and then the transmitter 3 housed in the indicator lamp 1 will be described.

In the following description, in the state where the indicator lamp 1 is mounted on the wall surface 5, the front side of the wall surface 5 is referred to as the front side, and the back side of the wall surface 5 is referred to as the back side and the back side.

[Indicator]

As shown in FIG. 1, the indicator lamp 1 has an outer peripheral wall portion 7 composed of a substantially cylindrical body, and a flange-shaped mounting portion protruding outward from the outer peripheral surface of the front end side of the outer peripheral wall portion 7 toward the outside 9; in front of the outer peripheral wall 7 The inner side is formed into a ring-shaped light-emitting display portion 11; and the transmitter housing portion 13 connected to the light-emitting display portion 11 and formed inside the outer peripheral wall 7.

Furthermore, as shown in FIG. 3, a space portion 14 is formed between the outer peripheral wall portion 7 and the peripheral wall of the light-emitting display portion 11 and the transmitter housing portion 13 formed inside thereof, and the space portion 14 is usefully provided To mount the substrate 17 of the light emitting element 15.

In addition, the outer peripheral wall portion 7, the light-emitting display portion 11, and the transmitter accommodating portion 13 correspond to the body portion of the present invention.

<Peripheral wall section>

The outer peripheral wall portion 7 is formed into a substantially short cylindrical shape by a light-transmitting resin member.

<installation department>

The attachment portion 9 is for attaching the indicator lamp 1 to the wall surface 5 and, as described above, is formed into a substantially square flange shape protruding outward from the outer circumferential surface on the front end side of the outer circumferential wall portion 7.

As shown in FIGS. 1 and 2, the four corners of the mounting portion 9 are provided with screw holes 9 a for mounting the display lamp 1 on the wall surface 5.

<Light-emitting display section>

As shown in FIGS. 1 to 3, the light-emitting display portion 11 is formed in a ring shape inclined from the inner peripheral edge of the mounting portion 9 toward the inside and the back side. In addition, in FIG. 2, the light-emitting display unit 11 is colored to clearly show it.

As shown in FIG. 3, the light-emitting display portion 11 is formed so as not to protrude greatly from the wall surface 5 in the installed state of the display lamp 1, and is not to be sideways by an article like a conventional bulging type display lamp Damaged by collision.

The light-emitting display portion 11 is composed of, for example, a red translucent member, and transmits light from the light-emitting element 15 (refer to FIG. 3) accommodated in the space portion 14 to transmit light brightly. The arrangement relationship between the light-emitting display unit 11 and the light-emitting element 15 will be described later.

<Transmitter Storage Department>

As shown in FIGS. 1 to 3, the transmitter accommodating portion 13 is formed in a segment shape from the inner circumference to the inner side and the back side of the light-emitting display portion 11, and the bottom of the segment becomes a transmitter for mounting the transmitter 3 The letter mounting face 21 (refer to FIG. 1 and FIG. 2).

The transmitter mounting surface 21 is composed of a translucent member and a flat surface with an opening in the center, and screw holes 21a for mounting the transmitter 3 are provided on both sides.

The face 21 is attached to the transmitter, and the reflector 25 is attached so as to cover the entire surface of the face 21 where the transmitter is installed. By attaching the reflective plate 25, the light of the light-emitting element 15 is reflected by the reflective plate 25 and diffused by the surface of the substrate 17, etc., and is emitted as indirect light from the light-emitting display portion 11 to the outside. In this way, by attaching the reflective plate 25, the light-emitting display portion 11 can emit light with indirect light, and the whole light-emitting display portion 11 can emit light brightly.

Regarding this point, the series gives an example, which will be explained based on Fig. 4 and Fig. 5. FIG. 4 shows the state in which the light-emitting element 15 emits light when the reflective plate 25 is not attached, and FIG. 5 shows the state in which the reflective plate 25 is attached as shown in FIG. 4. In addition, in FIG. 4, the portion having the light-emitting element 15 is displayed in white.

As shown in Figure 4, the light-emitting element 15 is arranged on the mounting surface of the transmitter The back side of 21, so when the reflector mounting surface 21 is not attached with the reflective plate 25, the light of the light emitting element 15 will not be reflected, but will penetrate the transmitter mounting surface 21, which is not helpful to make the light shine The display unit 11 emits light.

On the other hand, when the reflective plate 25 is attached, as shown in FIG. 5, the light reflected by the reflective plate 25 enters the light-emitting display portion 11 as indirect light, so that the light-emitting display portion 11 as a whole is bright Glow to enhance visual recognition. Thereby, even if the number of the light-emitting elements 15 is reduced, the necessary visual recognition can be ensured, so that the power saving effect can also be obtained.

<substrate>

As shown in FIG. 1, the substrate 17 is formed by a circular plate with a central opening, and a light-emitting element 15 as a light-emitting source is arranged on the front surface side of the substrate 17.

As shown in FIG. 3, the substrate 17 is mounted so that the front side faces the transmitter mounting surface 21.

In this manner, by mounting the substrate 17, the light-emitting element 15 is arranged to face the transmitter mounting surface 21 in the space 14 (refer to FIG. 2 ).

FIG. 2 is a front view of the display lamp 1 with the substrate 17 mounted, and the light-emitting element 15 on the substrate 17 is shown in broken lines.

The light-emitting element 15 is arranged such that the light-emitting element 15 located closest to the left and right ends of the substrate 17 is closer to the light-emitting display portion 11 than the other light-emitting elements 15, that is, on the outer peripheral side (see FIG. 2 ). In the example of FIG. 2, a part of the light emitting elements 15 at the left and right ends are arranged so as to be engaged with the light emitting display portion 11 when viewed from the front.

In this way, by arranging the light emitting element 15, both sides of the light emitting display section 11 The department glows brighter than the upper and lower parts. In addition, by making the difference in brightness between the two sides and the upper and lower parts, compared with the case where the light-emitting display section is lit with uniform brightness, visual recognition is improved.

In addition, making both sides of the light-emitting display section 11 emit light brighter than the upper and lower parts means that both sides are relatively brighter than the upper and lower parts, and does not mean that both sides are absolutely bright. Furthermore, the two sides refer to the concept used to distinguish it from the upper and lower parts, and do not strictly specify a certain area.

The transmitter 3 is set at a certain height (80 to 150 cm from the ground), and the display lamp 1 integrated with the transmitter 3 is also set at the same height. That is, the indicator lamp 1 is provided at a position close to the line of sight of a person. When the display lamp 1 is viewed at a small angle from the vicinity of the wall surface provided with the display lamp 1 set at the above-mentioned height, the light-emitting display portion 11 cannot see the side on the front side thereof, and the side on the back side is Must be visually recognizable (see Figure 7). Therefore, by making both sides of the light-emitting display portion 11 emit light brightly, there is an effect that when the display lamp 1 is mounted on the wall surface 5 and the display lamp 1 is viewed at an inclination along the wall surface 5, it can be sure地VISUALLY RECOGNIZE DISPLAY LIGHT 1.

Furthermore, since both sides of the light-emitting display portion 11 emit light brightly, the upper and lower sides of the light-emitting display portion 11 are relatively darkened, so that the light-emitting mode of the light-emitting display portion 11 is changed, thereby improving visual recognition.

[Transmitter]

Next, the transmitter 3 accommodated in the transmitter accommodating portion 13 of the display lamp 1 described above will be described based on FIGS. 6 and 7.

The transmitter 3 is shown in Figure 6 and has the following: when pressed, it sends a fire The signal button 31; the button storage portion 33 formed of a circular plate shape; and the transmitter body portion 35 formed on the back side of the button storage portion 33.

The key storage portion 33 is provided with a window door 33a for a telephone socket, which is provided inside the key storage portion 33 and covers the telephone socket (not shown) to which the microphone is connected so as to open and close freely.

The transmitter body 35 is formed in a box shape, and a switch and the like (not shown) linked to the key 31 are housed inside.

As shown in FIG. 7, when the transmitter 3 is accommodated in the transmitter accommodating portion 13 of the display lamp 1, it is arranged to be surrounded by the light-emitting display portion 11 and substantially flush with the inner periphery of the light-emitting display portion 11. In this state, since the light-emitting display portion 11 of the display lamp 1 emits light, the position of the transmitter 3 can be displayed.

The effect of the use state (state in which the transmitter 3 is accommodated and the light-emitting display unit 11 emits light) of the display lamp 1 configured as above will be described based on FIG. 8.

As shown in FIG. 8, the light-emitting display portion 11 of the indicator lamp 1 normally emits brightly and displays the position of the transmitter 3 (disaster prevention equipment).

As described above, both sides of the light-emitting display portion 11 emit light more brightly than the upper and lower portions. Therefore, when the display lamp 1 is viewed from the slope along the wall surface 5, the display lamp 1 can be reliably visually recognized. Furthermore, both sides of the light-emitting display unit 11 are brighter than the top and bottom, and the light-emitting mode of the ring-shaped light-emitting display unit 11 may change. Therefore, when a person looks at the display lamp 1 while moving, the position of the line of sight will change, so the angle of viewing the display lamp 1 will also change With this, the areas of both sides and upper and lower surfaces of the light-emitting display portion 11 that can be visually recognized change. In this way, the viewing mode of the display lamp 1 will change, and the visual recognition will be further improved.

In addition, the light-emitting display portion 11 is formed with an inclined surface toward the center, as shown in FIG. 2, the visibility from the front side is good, and as shown in FIG. 7, the visibility from the side is also good.

In addition, in this example, the transmitter 3 is provided in the ring of the ring-shaped light-emitting display portion 11 and the above-mentioned inclined surface is formed, so the light-emitting display portion 11 can illuminate the key 31 of the transmitter 3, Even in a dark place, the operation of the transmitter 3 and the connection between the receiver and the telephone jack can be easily performed.

In addition, the display lamp 1 does not have a portion that protrudes greatly from the wall surface 5, and there is no case where the display lamp 1 of the bulging type as usual is hit by an object from the side and is damaged.

In addition, in the above description, as shown in FIG. 3, an example is shown in which the arrangement is directed toward the front of the display lamp 1, but the arrangement of the light-emitting elements 15 is not limited to this. As shown in FIG. 9, the light-emitting element 15 may also be arranged toward the center of the display lamp 1. By arranging in the above manner, the visibility of the display lamp 1 from the side can be increased. In addition, in FIG. 9, the same device symbols as those in FIG. 3 are indicated.

Alternatively, a configuration in which a portion where the light-emitting element 15 is disposed toward the front side and a portion where the light-emitting element 15 is disposed toward the center of the display lamp 1 may be mixed. However, in any case, as in the case shown in FIG. 3, the light-emitting elements 15 arranged on both sides are arranged closest to the light-emitting display portion 11 than the other light-emitting elements 15.

In addition, in the above description, in order to make both sides of the light-emitting display section 11 emit brighter than the top and bottom, the example in which the light-emitting elements 15 arranged on both sides are arranged closest to the light-emitting display section 11 than the other light-emitting elements 15 is illustrated. For other methods for making both sides of the light-emitting display portion 11 emit brighter than the top and bottom, for example, the distance to the light-emitting display portion 11 of each light-emitting element 15 may be equalized, and the two side portions The brightness of the light-emitting element 15 is set to be higher than the brightness of the upper and lower parts. Alternatively, both the arrangement and brightness of the light emitting element 15 may be adjusted.

Furthermore, the light emitting elements 15 may not be arranged up and down, and the upper and lower portions of the light emitting display portion 11 may be relatively darkened.

In addition, a reflective material may be attached to the outer peripheral surface of the outer peripheral wall portion 7 to reflect the light on the inner peripheral side. In this way, the light emitted from the light-emitting element 15 or the light reflected to the reflective material does not pass through the outer peripheral wall portion 7 and passes through the back side of the wall surface 5, and the light-emitting display portion 11 can emit light efficiently.

In addition, by attaching the reflective material to the upper and lower surfaces of the light-emitting display portion 11, the light from the light-emitting element 15 toward the upper and lower surfaces can also be diffused, so that the upper and lower surfaces do not emit light, and only the two sides are stronger Glowingly.

In addition, although the example of a circular ring is taken as the light-emitting display portion 11, the light-emitting display portion 11 of the present invention is ring-shaped and is not limited to a circular ring, but for example, it may be a rectangular ring shape or a polygonal shape ring.

The translucent member constituting the light-emitting display section 11 is not limited to red. The light-emitting display portion 11 may be composed of a colorless and transparent translucent member. At this time, by making the light-emitting element 15 a red LED, the light-emitting display portion 11 displays red.

In addition, in the above description, although the transmitter accommodating portion 13 is provided inside the ring of the light-emitting display portion 11 and the transmitter 3 is accommodated, the transmitter 3 may be provided outside the display lamp 1. At this time, a red circular plate for covering the inside of the ring of the light-emitting display section 11 may be provided inside the ring of the light-emitting display section 11 instead of the transmitter 3.

In this way, the display lamp of the present invention may be configured as the display lamp 1 integrally formed with the transmitter 3, or may be configured as a display lamp of a different body type from the transmitter 3, and can be appropriately selected according to the situation.
