[0003]

[Problems to be solved by the device]

 The above-mentioned conventional flashlight is a lighting means that can be easily used in a dark place or in a dark place.However, since the conventional flashlight does not have a means to inform the user of its position, a flashlight can be used during a power failure at night. Often it is difficult to find the light itself. In such a case, the entire interior of the building will be completely unlit, dark and invisible, which is extremely dangerous in an emergency such as an earthquake. Further, in the conventional flashlight, there is a possibility that a dry battery is exhausted or a rechargeable battery is neglected, so that it cannot be actually used as an illumination means in an emergency. The present invention has been made in order to solve such a problem.

That is, the battery is maintained in a state in which it can be used at all times, and the position of the emergency light can be constantly confirmed by the auxiliary light-emitting body even at night. When the ON-OFF switch is turned ON and the plug is inserted into the AC power outlet, if the AC power is not connected to the input terminal of the electric circuit due to power failure, etc. The main illuminator lights up and illuminates the inside of the building. In this case, even if the plug is pulled out from the AC power supply, the state in which the AC power supply is not connected to the input terminal of the electric circuit remains unchanged. It can be used as a portable lighting means in the same way as a conventional flashlight. At this time, ON-OFF of the main light-emitting body is controlled by an ON-OFF switch like a conventional flashlight.

[0006]

[Embodiment of device]

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 is a case of an emergency lighting. As shown in FIG. 2, an electric circuit 5 is arranged on a substrate 3 in the case 1, and in the electric circuit 5, a main light emitting body 7 as a lighting means, an auxiliary issuer 9 as an auxiliary lighting means, The ON-OFF switch 11, the rechargeable battery 15, and the plug 17 are connected. The main light emitter 7, the auxiliary issuer 9, the ON-OFF switch 11, the rechargeable battery 15, and the plug 17 are arranged at predetermined positions in the case 1. The main light emitter 7 is covered with a cover 19 made of transparent plastic or the like. The rechargeable battery 15 is, for example, an alkaline storage battery such as a nickel cadmium battery. For example, a small light bulb is used as the main light-emitting body 7 as the illumination means and the auxiliary issuer 9 as the auxiliary illumination means. In the present invention, when the AC power supply 25 is not connected to the input terminal of the electric circuit 5, ON-OFF of the main light emitter 7 is selected by the ON-OF F switch 11, and the AC power supply 25 is input to the input terminal of the electric circuit 5. When is connected, the battery 15 is charged, the auxiliary light emitter 9 is turned on, and the main light emitter 7 is turned off. Also, as shown in FIGS. 4 and 5, the plug 17 has a plug 17 so that the AC power supply 25 distributed to the AC power supply 25 can be used even when the plug 17 is inserted into the outlet 23 of the AC power supply 25. It is desirable to connect the outlet 21 in parallel with the plug 17. Reference numeral 27 is another plug corresponding to the outlet 21, and reference numeral 29 is its code.

Next, two usage states of the emergency light according to the present invention will be described as an example together with the electric circuit 5 shown in FIG.

(1) When the plug of the emergency lighting is plugged into the outlet of the AC power source The emergency lighting according to the present invention, as shown in FIG. 4, always has the ON-OFF switch 11 turned ON. Insert the plug 17 into the outlet 23 of the AC power supply 25. The input terminals A-A 'of the electric circuit 5 are connected to the AC power supply 25, and the rechargeable battery 15 is charged via the power supply circuit 31. The auxiliary light-emitting body 9 as an auxiliary illuminating device is turned on by using the AC power supply 25 as a power source regardless of the ON / OFF state of the ON-OFF switch 11. Further, while the rechargeable battery 15 is being charged, the main light emitting body 7 as an illumination means does not light even if the ON-OFF switch 11 is turned ON. This is because the resistance R1 is set so that the voltage between the base and the emitter of the transistor 33 in the electric circuit 5 rises to the voltage VF or less, so that the transistor 33 does not conduct (no collector current flows). At the time of a power failure, the input terminals AA ′ of the electric circuit 5 are not connected to the AC power supply 25, so the electric circuit 5 becomes the bias circuit shown in FIG. 8, while the ON-OFF switch 11 is in the ON state. Since it is in the state, the main light emitting body 7 is automatically turned on as a lighting means.

(2) When the plug of the emergency lighting is pulled out from the outlet of the AC power source and the emergency lighting is used as a portable lighting means In this case, the input of the electric circuit 5 is performed as in the case of the above power failure. Since the terminals AA 'are not connected to the AC power supply 25, the electric circuit 5 becomes the bias circuit shown in FIG. Therefore, as shown in FIG. 3, when the ON-OFF switch 11 is turned ON, the main light emitting body 7 as the lighting means is turned on, and when the ON-OFF switch 11 is turned off, the main light emitting body 7 as the lighting means is turned off. . In this case, the collector direct current IC flows due to the base direct current IB flowing. The reference numeral 13 in FIG. 3 indicates the hand of the person who holds the emergency light.

[Effect of device]

 As described above, in the emergency light according to the present invention, if the ON-OFF switch is turned ON and the plug is inserted into the outlet of the AC power supply, the AC power supply is connected to the input terminal of the electric circuit. When connected, the rechargeable battery is automatically charged, the auxiliary light emitter is turned on, and the main light emitter is turned off. That is, the battery is maintained in a state in which it can be used at all times, and the position of the emergency light can be always confirmed by the auxiliary light-emitting body even at night. In this case, when the AC power supply is not connected to the input terminal of the electric circuit due to a power failure or the like, the main light emitter lights up to illuminate the inside of the building. In other words, the emergency light according to the present invention functions as a so-called emergency light. On the other hand, the emergency light according to the present invention can be used as a portable lighting means in the same manner as a conventional flashlight by pulling out the plug from the AC power outlet. At this time, ON-OFF of the main light emitter is controlled by an ON-OFF switch as in the conventional flashlight.
