The present invention will be more clearly understood from the following description, in comparison with the prior art, with reference to the accompanying drawings.

2 is a plan view of a mobile phone battery that can be used as a flashlight according to the present invention. Figure 2a shows the front attached to the mobile phone in the state that the battery coupled to the mobile phone is coupled to Figure 2b shows the back of the mobile phone battery. Referring to FIGS. 2A and 2B, a battery 10 coupled to a mobile phone and receiving electricity from a charger to charge electric charges, a first light emitting diode 11 and a second light emitting diode attached to the battery to emit light (12), a switch 13 for controlling the flow of current supplied to the second light emitting diode, a terminal 14 for receiving electricity from the outside, and a terminal 15 for supplying electricity to the mobile phone.

The battery 10 according to the present invention is supplied with electricity by a terminal 14 which receives an electric input from the outside, and the charged electric charge is transferred to the mobile phone through the terminal 15 for supplying electricity to the mobile phone. The front surface of the battery 10 has a first light emitting diode 11 is installed on the top of the battery so that the battery is well visible in the state that the battery is plugged into the charger, the battery terminal (14) on the back of the battery (10) The second light emitting diode 12 is installed where there is a part. In addition, a switch 13 is provided on the side of the battery 10 to control the flow of current through the second light emitting diode 12 so that the second light emitting diode 12 emits light by the operation of the switch 13. To help.

Therefore, when the battery is charged, the first light emitting diode 11 emits light during power failure so that the battery can be easily found by the light of the first light emitting diode 11 in a dark space. In addition, the battery 10 may be used as a flashlight through a switch operation to allow a current to flow in the second light emitting diode 12.

In addition, a separate additional terminal 16 is provided at the bottom of the rear side of the battery 10 in which the terminal 14 receiving the electricity from the charger is formed.

Figure 3 shows an equivalent circuit diagram of a mobile phone battery and a charger for charging the battery that can be used as a flashlight according to the present invention. Referring to Figure 3 as follows.

The charger 20 according to the present invention has an AC / DC converter 21 for converting an AC input into a direct current and a first +/- terminal 24 for receiving a direct current output from the AC / DC converter 21 and outputting it to the outside. And an AC input sensing device 22 and an AC input sensing device 22 for monitoring a first additional terminal 26 electrically connected to the + terminal and an AC input input from the outside and generating a constant signal when the AC input is disconnected. It consists of a first switch 23 to be connected or disconnected between the + terminal and the additional terminal 26 by the signal of. The first switch 23 is to be in the open state in the normal state.

And, the battery 10 according to the present invention is to be charged by applying a DC power to the battery cell 17 and the battery cell 17 to charge the charge and connected to the first + /-terminal 24 of the charger 20 Second +/- terminal 14 to receive the DC power output from the charger 20, the second additional terminal 16, the second additional terminal to be connected to the first additional terminal 26 of the charger It is connected to the first light-emitting diode 11 and the battery cell 17 is connected between the terminal 16 and the-terminal of the second + /-terminal 14 and connected between the second additional terminal 16 and the-terminal The second light emitting diode 12 and the second light emitting diode 12 is composed of a second switch 13 to block the flow of current. Like the first switch 23, the second switch 13 is also in the open state in a general state. In addition, the first light emitting diodes 11 and the second light emitting diodes 12 are connected to the resistors, respectively, so that a constant voltage drop occurs in the resistors, so that the charges charged in the battery 10 are stored in the first light emitting diodes 11 and the first light emitting diodes 11 and 12. 2 allows the light emitting diodes 12 to flow.

Referring to the flow of current in accordance with the circuit diagram, the charger 20 generally receives an AC input so that the battery 10 plugged into the charger 20 is charged. However, when the AC input is interrupted by the power failure, the AC input sensing device 22 of the charger 20 determines that the AC input is blocked and transmits a certain signal. Then, the first switch 23 provided between the + terminal and the first additional terminal 26 is brought into a short state by using the signal of the AC input sensing device 22.

When the first switch 23 is short-circuited, the first + /-terminal 24, the first switch 23, the first additional terminal 26, the first light emitting diode 11 and the battery 17 The closed loop is formed to flow through the closed loop in which the charge charged in the battery cell 17 is formed, thereby emitting light from the first light emitting diode.

Therefore, in case of power failure, the battery 10 plugged into the charger 20 can be easily found in a dark state, and measures for power failure can be performed. In this case, when the battery 10 is disconnected from the charger 20, the battery and the charger are not electrically connected, and a closed loop is not formed in the battery 10 and the charger 20, and the battery 10 is charged in the battery 10. Since no charge flows, the first light emitting diode 11 cannot emit light.

Then, when the second switch 13 of the battery 10 is pressed while the battery 10 is separated from the charger 20, the battery cell 17, the second light emitting diode 12, and the second switch 13 The closed loop is formed to allow the second light emitting diode 12 to emit light. The second switch 13 may be short-circuited or open by human operation to control the light emitted from the second light emitting diode 12.

In addition, the second switch 13 can be operated even when the battery 10 is in contact with the mobile phone so that the battery 10 can be used as a flashlight in the contact state with the mobile phone. Thus, it can be effectively used in the dark night.

The AC power monitoring device 22 used in the present invention can be simply configured using a port coupler, etc., and the first switch 23 can use a relay or a semiconductor switch.

Mobile phone battery and mobile phone battery charger that can be used as a flashlight according to the present invention is to connect the light emitting diode to the battery attached to the mobile phone in an emergency so that the light emitting diode is lit by the charging charge charged in the battery.

In particular, the battery and the light emitting diodes are connected to each other through a switch external to the battery, and when the switch is turned on, the light emitting diodes emit light so that the battery can be used as a flashlight. In addition, if the AC power input to the battery charging terminal of the charger is cut off while charging the battery using the charger, the charging charge in the battery flows to the light emitting diodes to emit light from the light emitting diodes.

Therefore, since the AC power input to the charging terminal is cut off in an emergency such as a power failure, when the battery is plugged into the charger, the light emitting diode emits light, so that the battery can be easily found in the dark as well as measures for power failure. By using the switch on the battery, the light emitting diode of the battery keeps emitting light so that the battery can be used like a flashlight when a flashlight is needed.
