Description

Technical Field

[0001] The present disclosure relates to an indicator light used to notify the position of disaster prevention equipment.

Background Art

[0002] As one of the disaster prevention facilities that are operated during a fire and contribute to fire extinguishing activities, there is a transmitter installed in a fire monitoring area that manually notifies a fire. In addition, as disaster prevention equipment used to notify the position of disaster prevention equipment, there is an indicator light.

[0003] A transmitter with a ring-shaped indicator light in which the transmitter and the indicator light are integrated is widely recognized (see, for example, Non-Patent Document 1). According to the transmitter with a ring-shaped indicator light described in Non-Patent Document 1, by making the indicator light ring-shaped and integrating it with the transmitter, a compact design is realized while maintaining the functions of the transmitter and the indicator light respectively.

[0004] By using such a transmitter with a ring-shaped indicator light, it is possible to achieve harmony with the space design, which is not conspicuous during normal times and blends into the space, while providing visibility that clearly indicates the installation location of the transmitter when necessary, and a disaster prevention system can be constructed.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Indicator lights play an important role in disaster prevention systems by indicating the location of disaster prevention equipment. When the disaster prevention equipment is a transmitter, this role can be effectively fulfilled by integrating the transmitter and indicator light, as disclosed in Non-Patent Document 1.

[0007] On the other hand, indicator lights are sometimes installed as standalone units near transmitters, and when indicating the location of disaster prevention equipment other than transmitters, it is common to install standalone indicator lights near the disaster prevention equipment.

[0008] Indicator lights are designed to illuminate at a certain brightness to ensure visibility under specific conditions. However, the indicator light color must be red, which, for example, results in insufficient light output for use as a lighting fixture. Furthermore, red indicators tend to appear dim despite their light output.

[0009] Therefore, especially when using indicator lights as standalone units, it is expected that their value can be enhanced by providing additional display functions in addition to their primary function of indicating the location of disaster prevention equipment.

[0010] This disclosure is made to solve the above-mentioned problems and aims to provide an indicator light that can be used for purposes other than its original purpose of indicating the location of disaster prevention equipment. [Means for solving the problem]

[0011] The indicator light relating to this disclosure is equipped with a main light source for displaying red for disaster prevention purposes, and is an indicator light used in a disaster prevention system, further equipped with a secondary light source for displaying for purposes other than disaster prevention. [Effects of the Invention]

[0012] According to this disclosure, it is possible to obtain an indicator light that can be used for purposes other than its original purpose of indicating the location of disaster prevention equipment. [Brief explanation of the drawing]

[0013] [Figure 1] This is a functional block diagram of an indicator light according to Embodiment 1 of the present disclosure. [Figure 2] This is a top-down cross-sectional view of the indicator light according to Embodiment 1 of the present disclosure installed on a mounting surface. [Figure 3] This is an explanatory diagram showing a cover provided on the outside of the indicator light according to Embodiment 1 of the present disclosure, which allows the main light emitted by the main light source and the secondary light emitted by the secondary light source to pass through. [Figure 4] This is an explanatory diagram showing the display state using the main light source and secondary light source of the indicator light according to Embodiment 1 of this disclosure. [Figure 5] This is an explanatory diagram showing the display state by a secondary light source when a thin indicator light is used as the indicator light according to Embodiment 1 of this disclosure. [Modes for carrying out the invention]

[0014] Hereinafter, preferred embodiments of this disclosure will be described with reference to the drawings. The indicator light described herein is technically characterized by its additional display function, which, in addition to its original red display function for indicating the location of disaster prevention equipment, can also be used for other purposes, such as as illumination during power outages.

[0015] By incorporating these technical features, it is possible to create an indicator light that can illuminate the area where it is installed as needed, ensuring sufficient light output for use beyond its original purpose.

[0016] Embodiment 1. Figure 1 is a functional block diagram of an indicator light according to Embodiment 1 of the present disclosure. The indicator light 20 shown in Figure 1 is a device used in a disaster prevention system and is configured to include a main light source 21 and a sub-light source 22.

[0017] The main light source 21 is a light source that outputs the main light emission to display red for disaster prevention purposes and to fulfill its original role as an indicator light 20.

[0018] On the other hand, the sub-light source 22 is a light source added to realize a display function that can be used as illumination light during a power outage or the like, and outputs secondary light emission for performing display for purposes different from disaster prevention use. As the sub-light source 22, a light source that performs display with a color other than red can be adopted.

[0019] FIG. 2 is a view seen from above of the state where the display lamp 20 according to Embodiment 1 of the present disclosure is installed on the mounting surface 1. As shown in FIG. 2, in terms of specifications, it is necessary to be able to visually recognize that the display lamp 20 emits red light at an angle of 15° or more from the mounting surface 1 in its left-right direction.

[0020] If the region less than 15° from the mounting surface 1 in FIG. 2 is defined as region S1, in this region S1, it becomes possible to incorporate a configuration for performing secondary light emission by the sub-light source 22 without disturbing the range of red display according to the specifications.

[0021] FIG. 3 is an explanatory view showing a cover 23 provided outside the display lamp 20 according to Embodiment 1 of the present disclosure for transmitting the main light emission by the main light source 21 and the secondary light emission by the sub-light source 22. The cover 23 transmits the main light emission by the main light source 21 and the secondary light emission by the sub-light source 22.

[0022] Specifically, as shown in FIG. 3, the cover 23 is formed to include a first cover 23a for displaying the main light emission in a region other than region S1 and a second cover 23b for displaying the secondary light emission in region S1.

[0023] The first cover 23a is configured with red so that the main light emission can be visually recognized as red display. On the other hand, the second cover 23b can be configured with a color for displaying the secondary light emission in a desired color. For example, by using a transparent cover, white display can be performed. Hereinafter, the case of performing white display by secondary light emission will be described as a specific example.

[0024] Figure 4 is an explanatory diagram showing the display state using the main light source 21 and sub-light source 22 of the indicator light 20 according to Embodiment 1 of this disclosure. In Figure 4, the display state when the indicator light 20 is mounted on the mounting surface 1 is shown as a front view.

[0025] In the specific example shown in Figure 4, when viewed from the front of the indicator light 20, the main light source 21 is installed approximately in the center inside the indicator light 20, and the secondary light sources 22 are installed in four locations inside the indicator light 20: top, bottom, left, and right.

[0026] The main light source 21 outputs its main light so that it passes through the first cover 23a shown in Figure 3, allowing red light to be perceived at an angle of 15° or more from the mounting surface 1. On the other hand, the secondary light source 22 outputs its secondary light so that it passes through the second cover 23b shown in Figure 3, allowing white light to be perceived in region S1 at an angle of less than 15° from the mounting surface 1.

[0027] In particular, by arranging the sub-light source 22 and the second cover 23b so that the mounting surface 1 can also be illuminated by the sub-emitting light output from the sub-light source 22, the mounting surface 1 within the area S2 shown in Figure 4 will be illuminated in white. As a result, the function of the sub-light source 22 enables a display function that can be used as illumination light in the event of a power outage.

[0028] In addition, a slim indicator light 20A may be used instead of the indicator light 20 shown in Figures 2 and 3. Therefore, a specific configuration for incorporating secondary light emission from a secondary light source 22 into the slim indicator light 20A will be described next.

[0029] Figure 5 is an explanatory diagram showing the display state by the sub-light source 22 when a thin indicator light 20A is used as the indicator light 20 according to Embodiment 1 of this disclosure. In Figure 5, the positional relationships of the components of the thin indicator light 20A, namely the sub-light source 22, cover 23, resin 24, substrate 25, light guide 26, and installation guide section 27, are shown as partial cross-sectional views. Note that the main light source 21 is not shown in Figure 5.

[0030] The secondary light source 22 is mounted on a substrate 25 located below the resin 24 and outputs secondary light towards the top, which is the direction of the resin 24. The cover 23 consists of a first cover 23a for displaying red light using the primary light source 21 (not shown) and a second cover 23b for displaying white light using the secondary light source 22.

[0031] The light guide 26 is configured to reflect the secondary light emitted upward from the secondary light source 22 located at the bottom of the resin 24 in a direction along the surface of the resin 24, and to illuminate the outside through the second cover 23b.

[0032] The installation guide section 27, when combined with the cover 23, constitutes the housing for the slim indicator light 20A. Furthermore, the installation guide section 27, when inserted into the opening of the mounting surface 1, serves to install the slim indicator light 20A in the fire monitoring area.

[0033] The resin 24 is installed on the installation guide section 27 and has an opening 24a for fixing the light guide 26. The light guide 26 and the second cover 23b are positioned such that they can output secondary light in an area less than 15° from the mounting surface 1.

[0034] In Figure 5, the sub-light source 22 and light guide 26 are shown as one set. However, by using, for example, four sets of sub-light sources 22 and light guides 26, it is possible to illuminate the area S2 in four directions, as shown in Figure 4.

[0035] Therefore, even when using a thin indicator light 20A as the indicator light 20, by applying the configuration shown in Figure 5, the auxiliary light source 22 enables a display function that can also be used for other purposes as illumination light in the event of a power outage.

[0036] As described above, according to Embodiment 1, the indicator light is configured to have a primary light source for displaying red in disaster prevention applications, as well as a secondary light source for displaying in applications other than disaster prevention. In other words, in addition to its original function of displaying red to indicate the location of disaster prevention equipment, the indicator light is further equipped with a display function that can be used for other purposes, such as illumination during power outages.

[0037] As a result, the indicator light can illuminate the area where it is installed as needed, and can be used as an indicator light with sufficient light output for purposes other than its original intended use.

[0038] Furthermore, the indicator light according to this disclosure can be seen as a red light when viewed from a direction of 15° or more from the mounting surface, and can also emit secondary light in a portion that does not obstruct the range in which the red color can be seen.

[0039] For example, by making the section through which the secondary light passes through a clear structure and arranging a white LED as a secondary light source, the white LED can be turned on as needed, thus enabling it to function as an illumination light source.

[0040] In particular, by adopting a configuration that allows power to be supplied from the fire alarm receiver even during a power outage, indicator lights can be effectively used as illumination during a power outage.

[0041] Furthermore, the fire alarm receiver can be configured to illuminate the white LED only during a power outage, and also to prevent the red LED from illuminating during a power outage. In other words, by controlling the illumination using the fire alarm receiver, it is possible to illuminate either the original red indicator function or the indicator function that can be used as illumination during a power outage, or both, at a desired timing depending on the installation environment.
