Let [Constitution] In a display lamp lighting device in which a solar power source and a storage battery are used together to constantly light an indicator lamp, an auxiliary power source, an alarm means, and an alarm means simultaneously with switching to the auxiliary power source when the output of the storage battery drops. With storage battery monitoring. As a result, when the storage battery is insufficiently charged or its function deteriorates, it immediately switches to the auxiliary power source, blinks the indicator light, sounds an alarm buzzer, actively prompts replacement or inspection of the storage battery, and even when an unexpected abnormal situation occurs, fire extinguishing equipment It is possible to promptly take out items and to promptly guide the evacuation, thus improving safety.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power supply device for lighting an indicator light used to notify the presence of a fire extinguishing facility installation location, an emergency exit, etc. The purpose is to prevent the expansion of.

[0002]

[Prior Art]

 Fire extinguishing equipment installed in various places such as street corners, department stores, and factories is usually equipped with a red indicator light to clearly indicate its existence, and it is lit day and night. In addition to using general AC power supplies, these indicators have recently been equipped with solar power supplies using solar batteries for convenience of electrical wiring, convenience of movement, and power saving.

[0003]

[Problems to be solved by the device]

 In the solar power supply, the indicator light is usually turned on by a power source that is concentrated and electrified by a solar battery during the daytime, and reserve power is stored in a storage battery, which is used as a power source at night to turn on the indicator light. The indicator light may not be fully lit due to insufficient charging due to weather conditions or the life of the storage battery. In such a case, it becomes extremely difficult to find the location of the fire extinguishing equipment or to properly guide the evacuation due to the unknown emergency exit, especially when an emergency disaster occurs at night.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, the above-mentioned indicator lamp lighting device is improved so that it can be reliably turned on day and night, and in the case of the life of the storage battery, the abnormality is promptly notified to facilitate replacement. In this way, the safety is further enhanced.Specifically, in the case where a solar power supply and a storage battery are used together and the indicator lamp is constantly turned on, an auxiliary power supply, The present invention relates to a power supply device for lighting an indicator lamp, which comprises an alarm means and a storage battery monitoring means for activating the alarm means at the same time as switching to the auxiliary power source means when the output of the storage battery decreases.

[0005]

[Action]

 In the daytime, the indicator light is turned on by the solar power source and the storage battery is charged at the same time, and the indicator light is turned on by the output from the storage battery at night, but sufficient output can be obtained due to the life of the storage battery and insufficient charging. If there is no battery, the power source is automatically switched to the auxiliary power source by the storage battery monitoring means, and when the indicator lamp is switched from lighting to blinking, the alarm means that sounds the buzzer is activated at the same time to prompt an alarm.

[0006]

【Example】

 The specific contents of the present invention will be described below with reference to the embodiment of FIG. 1. 1 is a solar power source, 2 is a storage battery for storing the power generated by a solar battery, 3 is an indicator light, 4 is an alarm buzzer, 5 Is an auxiliary power supply, and 6 is a storage battery monitoring and power supply switching circuit.

The solar power source 1 is mounted on a surface of various devices to be displayed, such as fire extinguishing equipment, where sunlight is often exposed, and the output voltage thereof is 3.7 V and the output current is about 705 mA. It is preferable that the storage battery 2 has a rated voltage of 2.4 V and a rated capacity of about 4000 mAh and has a secondary battery charging function.

The indicator light 3 is preferably a miniature electric bulb of about 1.5 to 2.6 V or a high brightness light emitting diode (LED). As the alarm means, the above-mentioned indicator lamp 3 itself is made to blink, or the alarm buzzer 4 is made to sound intermittently, or the blinking of the indicator lamp 3 and the alarm buzzer are used together. Furthermore, as the auxiliary power source 5, a lithium battery, which is less likely to deteriorate in performance over a long period of time, is optimal, but the auxiliary power source 5 is not limited to this, and a general-purpose dry battery may be used. It should be noted that blinking the indicator light as the alarm means and making the alarm buzzer intermittent sound means an alarm, and at the same time, it has the effect of reducing the electricity usage of the auxiliary power supply 5 and prolonging the alarm time. 0. If the alarm buzzer is sounded at the same time that the indicator lamp is turned on by energizing for 1 second and not energizing for 1.9 seconds, the alarm time can be extended 20 times with the same auxiliary power supply.

The power supply switching circuit 6 disconnects the storage battery 2 and the indicator lamp 3 from each other and disconnects the auxiliary power source 5 and the indicator lamp 3 when the output voltage of the storage battery 2 drops below a certain value. It is something that can be made. However, this switching shall be performed by the storage battery monitoring and power supply switching circuit 6, and the output voltage of the storage battery 2 is constantly monitored, and when the voltage drops below a certain value, the power supply switching circuit 6 is automatically activated. The storage battery 2 and the indicator light 3 are disconnected and the auxiliary power source 5, the indicator light 3 and the alarm buzzer 4 are connected and activated.

In this case, for example, two Ni-Cad batteries having a rated voltage of 1.2V are connected in series and charged to make a total rated output voltage of about 2.4V, and one of the Ni-Cad batteries has a lifetime. If it becomes unusable due to, the total output will drop to about 1.2V. Therefore, when the total output becomes 1.5 V or less, the storage battery may be monitored and the operation of the power supply switching circuit 6 may be started.

When the power source is switched to the auxiliary power source 5 by monitoring the storage battery and switching the power source by the power source switching circuit 6, the auxiliary power source 5 causes the indicator lamp 3 to blink and light, or an audio alarm such as an alarm buzzer. The above-mentioned solar storage battery 2 is positively urged to be replaced or inspected by an alarm means 4 such as activating the container or simultaneously using both of them.

[0012]

[Effect of the device]

 As described above, the present invention uses a solar power source and a storage battery in combination to illuminate an indicator lamp at all times, and at the same time, switches to an auxiliary power source, an alarm means, and an auxiliary power source when the output of the storage battery drops. Since it is equipped with monitoring of the storage battery that activates the alarm means, if the storage battery is insufficiently charged or its function deteriorates due to its life, it is backed up immediately by the auxiliary power supply and the indicator light is kept on. At the same time, since the replacement or inspection can be actively displayed, even if an unexpected abnormal situation occurs, there is a delay in finding the location of the fire extinguishing equipment, especially when an emergency disaster occurs at night, or evacuation guidance due to unknown emergency exits. There is no delay, and no risky condition.
