Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a device for mounting a battery charge monitor in a lighting fixture with a built-in battery.

[Conventional technology]

Among lighting equipment with a built-in battery, if we take emergency lighting equipment as an example, if the regular power supply is cut off, it must be switched to the built-in battery to ensure safety lighting.
It is necessary to constantly check the state of charge of the built-in battery.

For this reason, the emergency lighting equipment is provided with a charging monitor, and the state of light emitted by the charging monitor is observed with the naked eye to confirm that the emergency lighting equipment can operate in a normal state. Since the charging monitor uses a light-emitting diode (LED), which consumes very little power, the charging monitor is usually installed on the exterior surface of the emergency lighting equipment, and the lighting status of the charging monitor can be visually checked. can be easily observed. However, in the case of a recessed emergency lighting fixture, as shown in FIG.
3, and the frame 2 is removable, and the cross-section inside the frame is extremely small, so it is impossible to install a charging monitor, so it is unavoidable to install the charging monitor inside the recessed lighting fixture. 3 was installed, and the light emitting state of the charge monitor 3 was checked through the transparent cover 13.

[Problem that the invention seeks to solve]

In the above conventional technology, the charging monitor of the embedded emergency lighting equipment must be observed through the transparent cover, so depending on the type of the transparent cover, it is extremely difficult to check the light emitting state of the charging monitor. . That is, the light-transmitting cover is not necessarily colorless and transparent, but is often milky white or amber, and amber has particularly low light transmittance, making it difficult to distinguish the small light emitting state of the LED. Further, even if the light-transmitting cover is colorless and transparent, if it has a minute uneven pattern, light will be diffused by the pattern, making it difficult to check the light emitting state of the charging monitor. As mentioned above, in emergency lighting equipment, it is difficult to check the lighting status of the charging monitor.

The charging monitor is installed as close as possible to the light-transmitting cover, but there are many types of light-transmitting covers, and they are generally interchangeable, so it is necessary that they do not get in the way when replacing lamps, etc. Therefore, it has been difficult to mount the charging monitor in a position where it can be easily checked visually.

An object of the present invention is to provide a device for attaching a charging monitor that makes it easy to check the state of light emission in a battery built-in lighting device such as a built-in emergency lighting device, regardless of the type of transparent cover.

[Means for solving problems]

The above object is achieved by guiding the light emitted from the charging monitor installed inside the battery built-in lighting device to the ms hole provided in a part of the surface of the device.

[Effect]

An example of a lighting fixture with a built-in battery is explained using the above-mentioned recessed emergency lighting equipment. Most of the internal volume of the above-mentioned recessed emergency lighting equipment is occupied by a charging device and a built-in battery. As the LED has an extremely small shape and the optical fiber is extremely thin, even if these parts are placed inside the emergency lighting equipment, there will be no problem in terms of the space it occupies. . The charging monitor installation device of the present invention is a part of the body of the emergency lighting device in which the light emitted from the LED installed at an arbitrary position is made to enter the optical fiber, and the optical fiber is exposed along the inner wall of the emergency lighting equipment. The optical fiber is guided to the frame, and the output light of the optical fiber is observed through the confirmation hole provided in the frame. Since the gap between the frame section and the main body of the emergency lighting equipment is narrow, almost no light reaches the inside of the frame even when the emergency lighting is on, and only a small amount of light reaches the inside of the frame through the optical fiber. It is possible to easily check the light emitting state of the LED.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view showing an embodiment of a device for mounting a charge monitor according to the present invention, and FIG. 2 is an enlarged cross-sectional view of a frame portion in the above embodiment. FIG. 1 shows a device for installing a charging monitor in a built-in emergency lighting device. 1 is the main body of the built-in emergency lighting device, and 2 is a translucent cover 13 that covers the end of the device main body 1. A frame for placing and holding, 9 a built-in battery, 10 a charging device, and an L provided in the charging device 10.
For the ED installation, an LED 3 is attached to the tip of the stand 4 to form a charging monitor. 11 is an emergency lamp, and 12 is an inspection switch. The input end 6 of the optical fiber 5 is installed so that the light emitted from the charging monitor ED 3 can be properly received at a position slightly away from the LED 3, and the optical fiber 5 is connected to the inner wall of the device main body 1 and built-in. The output end 7 of the optical fiber 5 is guided to the frame 2 through a gap with the battery 9, and is located near the confirmation hole 8 provided in the frame 2, so as to face the confirmation hole 8 as shown in FIG. It is installed in

In this embodiment configured as described above, the charging monitor L
Light emitted from the ED 3 enters the optical fiber 5 from the input end 6, propagates within the optical fiber 5 and exits from the output end 7 regardless of the curvature of the optical path of the optical fiber. Above output end 7
Since the frame 2 is provided with a confirmation hole 8 opposite to the frame 2, the light emission state of the LED 3 can be confirmed through the confirmation hole 8. Unlike in the case of optical communication, it is not necessary to use a high-grade optical fiber 5 because there is no need to transport optical signals over long distances with little attenuation.

Note that although the above embodiments have been described with respect to recessed emergency lighting equipment, regardless of the form of the recessed lighting equipment,
Further, the present invention is not limited to emergency lighting equipment, and can be widely applied to any lighting equipment equipped with a built-in battery, such as a guide light equipment, for example.
