At the same time, the air moves so that the inside of the body 1 is always kept dry.

4 to 7, the charging and charging detecting circuit 50 for detecting the state of charging or charging the battery BT1 is described in detail with reference to FIG. 4. When the AC power supply AC220V flows into the lead line, it is stepped down to the voltage required for charging by the step-down transformer T1, and the stepped down AC power is onion rectified by the rectifying diodes D3 and D4. Is converted into a DC voltage.

The rectified voltage is checked whether the commercial power is introduced through the AC power lamp LD1 and is stored in the storage battery BT1 through the backflow prevention diode D6 and the resistor R2 for controlling the charging current.

The resistor R2 is designed to adjust the resistance value to a current of 1 / 20C to trickle charge the battery BT1, and the fuse F2 protects the charging and charging sensing circuit 50 from overcurrent.

When the battery BT1 or the fuse F2 is disconnected and cannot be charged, the voltage of the point A of FIG. 4 and the point B of FIG. 4 is applied to the base of the transistor Q2 with a pulse current of 120 kV in the circuit, and the transistor turns to 120 kV. On-off will be repeated.

The point C voltage of FIG. 4 is a square wave voltage of 120 kV, and the second display part LD2 is repeatedly turned on and off, and the naked eye is identified to check whether the battery BT1 or charging is abnormal.

When the battery BT1 is not charged or there is a defect in the cell of the battery BT1 and the rated voltage is not reached, the voltage of the point A of FIG. 4 is lowered and the pressure of the point B of FIG. 4 that is negatively pressured by the resistors R4 and R5. Since the voltage is also lowered, the base voltage of the transistor Q2 is lowered so that the transistor Q2 is in the cut-off state, and thus the voltage at the point C of FIG. 4 is increased, so that the second display portion LD2 is turned on. Inform.

When the battery BT1 and the circuit are normally operated and charged, the voltage at the point A of FIG. 4 is increased due to the voltage of the battery, and the voltage at the point B of FIG. 4 is also generated above the operating voltage of the transistor Q2, thereby causing the transistor Q2 to be charged. ) Is turned on (TURN0-ON) is lowered the voltage point C in Figure 4, so that the second display (LD2) is turned off to indicate that there is no abnormality.

When the AC power is interrupted or the battery BT1 discharges to make an emergency light, the diode D6 keeps the voltage of the AC power light LD1 off, and the diode D7 is connected to the battery BT1. When disconnection is detected, the voltage charged by the flat capacitor C2 is blocked from entering the point A of FIG. 4, and the voltage of the point A of FIG. 4 is maintained at 120 kV.

The flat capacitor C2 smoothes the power of the display portion LD2 so that the display portion LD2 has a brighter brightness, and the resistor R3 maintains the operating currents of the display portion LD2 and the transistor Q2 appropriately. Use as a resistor to

The AC power supply side fuse F1 is for overcurrent blocking, and the switch SW1 uses an automatic return type to check the storage battery BT1 and the emergency lighting circuit by cutting off the AC power.

In the emergency power lighting circuit 60 shown in FIG. 5, when the commercial power is cut off, the voltage at the point A of FIG. 5 is lowered and the transistor Q1 is turned on so that the voltage of the battery is led through the transistor Q1. ) Is applied to turn on the power LED (41).

When AC power flows into the primary side of the power transformer T1, AC voltage is maintained at pins 6, 7, and 8, and rectified by the diodes D3 and D4, through the diode D5 to the transistor Q1. Since it is blocked by the reverse bias introduced to the point A, which is the base of the charging voltage or the voltage of the battery (BT1) does not flow to the LED module (40). The LED module 40 operates only with the voltage of the commercial power supply lighting circuit 70.

The flat capacitor C1 smoothes the voltage at point A so that the base voltage of the transistor Q1 is always kept high during commercial power supply, and the resistor R6 maintains the operating current of the transistor Q1 during emergency lighting. By adjusting the brightness of the power LED 41 installed in the LED module 40 at the time of emergency lighting.

Referring to the commercial power lighting circuit as shown in Figure 6, when commercial power (AC power) flows in, the secondary voltages 1 and 2 of the power supply transformer T1 depressurize the alternating voltage as necessary for lighting. The voltage of the rectified diode D2 is rectified by the smoothing capacitor C3 and supplied to the power LED 41 installed in the LED module 40 through the resistor R7.

On the other hand, the rectified voltage is applied to the base of the transistor Q3 through pins 4 and 3 of the resistor R8 and the photocoupler U1A to turn on the transistor Q3, thereby providing power installed in the LED module 40. The LED 41 is turned on.

The resistor R7 determines the brightness by adjusting the current of the power LED 41 installed in the LED module 40, and the resistor R8 is used as a bias of the porter puller U1A.

In addition, the emergency exit induction lamp of the present invention can turn off the power LED 41 in a commercial power state in order to save power, and provide a dedicated lighting line (not shown) for only charging the storage battery BT1 to perform remote control. To help.

When supplying the charging power of the battery BT1 to the commercial power supply, supply the charging voltage of the battery and the commercial power lighting voltage to the commercial power lighting circuit 70 by the power transformer T1, and control the on / off of the commercial power. do.

When AC power flows in, it rectifies to bridge rectifier diode (D1), and is supplied to pins 1 and 2 of porter puller (U1A) with current controlled by resistor (R10) to turn on pins 3 and 4 do.

Accordingly, power is supplied to the base of the transistor Q3 (point A in FIG. 7), and the transistor Q3 is operated to turn on the power LED 41 installed in the LED module 40.

When the switch SW1 is cut off, pins 3 and 4 of the porter puller U1A are cut off to lower the voltage at the point A of FIG. 7, so that the transistor Q3 is cut off to the LED module 40. The installed power LED 41 is turned off, and the capacitor C4 of FIG. 7 keeps the voltage of the porter puller U1A constant.

As shown in FIG. 2B, the reflector 16 of the upper case 10 is formed in a polygonal shape so that the light source irradiated through the power LED 41 is diffusely reflected and dispersed, and evenly illuminates the entire back side of the display panel 30. Therefore, even if one or a few power LEDs 41 are used, they are brighter than those using a plurality of LEDs (low brightness LEDs).

In addition, since the power LED 41 installed in the LED module 40 has a brightness of 1000 candela or more, a plurality of LEDs may be installed to display the LED brighter than the display panel 30.

The effect of the emergency exit induction lamp according to the present invention is to apply one power LED to the emergency staircase, emergency door, underground parking lot, train platform, etc. by irradiating the induction lamp display board with the reflected light and the direct light of an appropriate reflector so that a high-brightness light source can be expressed. It is effective to evacuate people quickly in case of emergency.

In addition, since the light source of one power LED is reflected by the reflector and the evacuation direction pattern is expressed clearly, there is an effect of inducing people to the evacuation direction in an emergency.

In addition, by using a power LED (Led) can be used semi-permanently without having to replace when in use, and as the structure inside the body of the induction lamp is simplified, there is an effect of preventing the size of the box larger than necessary.

In addition, since a small storage battery is used, there is an effect of preventing the entire volume from increasing when installed inside the body.

In addition, the use of semi-permanent power LEDs eliminates the problem of frequent replacement of the light source, and at the same time reduces the factors that can cause the failure to minimize the problem of repair and management due to the failure. .
