It is configured to be convertible to use or select 220V.

The down transformer unit 23 is a means for down-translating an AC power value of a predetermined size supplied from the AC power supply unit 21 by receiving a signal from the switch exchange unit 22 to an AC power value of another size. When the applied AC power of 110V / 220V is applied to the primary coil of the down transformer unit 23 by the operation of the switch exchange unit, the secondary coil induces an AC voltage stepped down to a predetermined voltage and is used for a plurality of full wave rectification.

In general, the battery 11 has a discharge end voltage. In the case of a nickel-cadmium battery, when the battery is discharged at a voltage lower than or equal to a certain voltage, the battery 11 may be damaged and may not be fully functional at the next charge. At the time of operation, it is set to prevent operation.

The charging voltage comparing unit 26 compares the amount of power charged by the down-transformer 23 with the maximum charging power amount (reference voltage) of the battery 11 to confirm the charging progress or completion of charging. If the voltage being charged is less than the maximum charging power of the battery 11, the charging indicator 27a is made to emit light, and the charging voltage reaches an approximation of the maximum charging power amount.

The battery 11 is mounted inside the emergency safety light 10 and charged as the power supply source source for supplying basic power to each part of the emergency safety light 10 after being charged by the charging device unit 20a. As a means of use, it is common to use two rechargeable Ni-Cd (nickel-cadmium) batteries in series.

The nickel-cadmium battery has a smaller power than ordinary batteries (manganese dioxide, alkaline), but is mainly used in portable devices such as an emergency safety lamp (10) of the present invention. The reference voltage of the nickel-cadmium battery is approximately About 1.2V, when charging a nickel-cadmium battery, about 0.2 to 0.25V per cell; when fully charged, about 1.2 to 1.45V; when two batteries are connected in series, about 2.75 ~ A power of about 2.9V is obtained, and the buffered power supply voltage is used as a reference voltage for charging and completing the battery 11 of the emergency safety light 10.

The micro-switch part 12 connects / disconnects the battery 11 and the charging device unit 20a as the emergency safety light 10 is contacted / detached from the cradle, thereby operating a current to operate the emergency safety light 10. Means for connecting or blocking the charge of the, is connected to the (-) terminal of the connection spring 13 connected to the battery 11 and the (+) electrode of the light emitting lamp 15, the emergency safety lamp (10) In the stand-by state where the micro switch unit 12 is pressed by the holder, the micro switch unit 12 is connected to the negative terminal spring, so that the battery 11 is kept in a charged state. When the lamp 10 is detached from the holder and the micro switch 12 is separated from the main body of the emergency safety lamp 10, the micro switch 12 is connected to the negative electrode of the battery 11. ) Is shorted and at the same time negative (-) toward battery 11 Current flows to emit the lamp.

The unstable multi-circuit unit 14 is connected to the positive electrode of the battery 11, and turns on / off two transistors Q1 and Q2 alternately to generate a waveform whose phase is inverted from each collector terminal. As shown in FIG. 3, the base terminal B2 of the transistor Q2 is connected to the collector terminal C1 of the transistor Q1 as shown in FIG. 3. The base terminal B12 of the transistor Q1 is connected to the collector terminal C2 of the transistor Q2, and the base terminal B1 of the transistor Q1 and the collector terminal of the transistor Q2 are connected. A capacitor C1 is connected between C2) and a buzzer is connected to the base terminal B1 of the transistor Q1.

When connected and powered on, one of the transistors Q1 and Q2 operates first due to a small difference in operating characteristics of the transistor.

If the transistor Q1 is ON and the transistor Q2 is OFF and the transistor Q1 is operated first, a reverse bias is applied to the base terminal B2 of the transistor Q2 by the charge of the capacitor C1. The base voltage drops and the transistor Q2 turns off, but the transistor Q1 keeps turning on the base current and finally generates buzzing sound from the buzzer 16.

However, when the transistor Q1 is ON and the transistor Q2 is OFF, the electric charge charged in the capacitor C1 is completely discharged and zero potential is applied to the base terminal B1, thereby making the transistor Q1 shut off. When the power is turned off and the capacitor C1 is charged again, power is applied to the base terminal B1, so that the transistor Q1 is energized and the buzzer is turned on, so that the transistor Q1 and the transistor Q2 are energized alternately. By repeating the over and off state, the oscillation continues.

The light emitting lamp 15 is a means to be turned on / off according to the operating state of the micro switch 12, the micro switch 12 if the micro switch 12 is pressed to the cradle by the emergency safety light (10). ) Is connected to the (-) terminal of the connection spring, so that it is turned off by maintaining the charging and standby state, and when the user escapes from the holder 20 to carry and use the emergency safety light 10 in case of emergency or fire, Since the switch 12 is connected to the negative electrode of the battery 11, current flows due to the positive electrode of the battery 11 that is energized together, and thus the light emitting lamp 15 automatically operates without an external switch operation. It turns on and can emit light.

The buzzer 16 is a means that is turned on / off according to the conduction state of the transistors Q1 and Q2 according to the operation of the unstable multi-circuit unit 14, the emergency safety lamp 10 from the cradle 20 When the microswitch 12 is separated from the battery, the micro switch 12 is connected to the (-) electrode of the battery and is energized. The battery is connected to the (+) electrode of the battery. Is turned on and transistor Q2 is turned off so that transistor Q1 operates first, the base terminal of transistor Q2 is reversely biased by the charge of capacitor C1, and the base voltage falls and transistor Q2 Is turned OFF, but the base current continues to flow through the transistor Q1 to maintain ON, and finally, the buzzer sound is generated from the buzzer 16, but the capacitor Q1 is turned ON and the capacitor Q2 is turned OFF. To (C1) The charged electric charge is completely discharged and the zero potential is applied to the base terminal B1, which causes the transistor Q1 to be cut off, the buzzer 16 is turned off, and the electric charge is charged to the capacitor C1 again. The transistor Q1 is energized and the buzzer 16 is turned on again. The transistor Q1 and the transistor Q2 are alternately turned on and off, and the buzzer 16 is also turned on. / OFF is repeated continuously.
