And a time constant circuit portion 511 composed of a variable capacitor C2, a resistor R1, and a variable resistor VR1, and a high voltage oscillation transformer T.

The power supply control unit 523 selectively supplies the circuit 51.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the apparatus of the present invention can be largely divided into single-sided light emission and double-sided light emission. In the case of single-sided light emission, as shown in FIGS. 2 and 5 (b), the planar light source 2 is formed at the center of the disc-shaped main body 1 having a central opening. ), And then, a light-transmitting hole 3 having a predetermined shape carved, printed, and powder-coated is installed at one side of the opening of the main body 1, and connected to a planar light source 2 at the other opening of the main body 1. What is necessary is just to install the reflecting plate 4 provided with the wire through groove 41 to be carried out, in this case, the wire passing groove 41 of the reflecting plate 4 is sealed and the floodlight 3 and the reflecting plate 4 are strong. Fix it on the main body 1 using an adhesive or the like to achieve complete waterproof.

In the case of the single-sided light emitting device as described above, the double-sided tape 42 may be installed on the rear surface of the reflecting plate 4 so as to be attached to a predetermined portion.

On the other hand, in the case of double-sided light emission, as shown in Figs. 1 and 5 (a), at the bottom of the main body 1, a fixture 11 having a wire passage groove 12 connected to the planar light source 2 is integrally integrated. In addition, another light emitting hole 3 is installed in the other opening in which the reflecting plate 4 is installed at the end of light emission, so that the light emitted from the planar light source 2 can be emitted from the light emitting holes 3 on both sides. It can be irradiated through, in this case also the fixture (11) wire passing groove 12 is subjected to the sealing and the floodlight (3) and the reflecting plate (4) is fixed on the body (1) using a strong adhesive, etc. It can be made completely waterproof.

Of course, a desired shape 32 is engraved intaglio on the inner surface of the floodlight 3 so that silver or opaque powder is coated or printed on the flat part 31 and powder coated in gold on the intaglio portion of the sculpture 32. Since the light is transmitted only through the engraving 32 of the intaglio, only the corresponding sculpture appears on the light transmission port.

At this time, the flash light of the planar light source 2 is a high voltage conversion circuit 51 for generating a high frequency AC high voltage by using a direct current or an alternating voltage and an auto-lighting circuit 52 for controlling a power supply voltage in response to ambient brightness. Is made by the control unit 5 having a).

FIG. 6 shows an AC high voltage generation circuit 51 for generating a high frequency DC power supply, which uses a high frequency oscillation transformer T and oscillation having time constants due to charging and discharging of a capacitor. It is a converter circuit diagram for converting a real current voltage into a high frequency AC voltage.

In this circuit operation, when the DC power switch SW is turned on, a voltage is applied to the base of the transistor Q1 through the resistor R1 and the variable resistor VR1, and the transistor Q1 is energized. In this way, when the transistor Q1 is operated, the current increases in the collector and the current increases in the primary coil of the transformer T. When the magnetic flux increases by this current, a high alternating voltage (0 V ~ 200 V) is induced in the secondary coil. In this case, the emitter voltage of the transistor Q1 and the connection point voltage level of the resistor R1 and the variable resistor VR1 and the capacitor C1 become equal, so that the transistor Q1 is normally cut off, The emitter voltage becomes higher than the connection point voltages of the resistor R1, the variable resistor VR1, and the capacitor C1 by the voltage induced on the secondary coil side of (T), so that the transistor Q1 remains turned on.

However, the transistor Q1 is turned off because the emitter voltage becomes lower than the connection point voltage between the resistor R1 and the variable resistor VR1 and the capacitor C1 due to the discharge of the capacitor C1 which continues after a certain time. .

After that, the transistor Q1 is delayed by the time constant of the resistor and the capacitor to become energized again, that is, when the capacitor is charged again after the transistor Q1 remains blocked until the capacitor is charged, the emitter voltage is increased. The transistor Q1 is switched to the energized state by being higher than the connection point voltage of the resistor R1, the variable resistor VR1, and the capacitor C1.

By repeating the above operation, a high frequency AC voltage can be obtained at the secondary coil side of the transformer T. If the values of the variable capacitor C2 and the variable resistor VR1 are properly changed, the secondary of the different frequency can be obtained. Voltage can be obtained, and the secondary coil voltage, current, and oscillation frequency of the transformer T can be determined so that the luminance of the planar light source 2 is usually determined between 0 cd / m and 200 cd / m.

In addition, the coil capacity of the transformer T can be appropriately changed according to the size of the planar light source 2, that is, the load size. The frequency changes when the values of the variable capacitor C2 and the variable resistor VR1 are changed. The color can be easily selected according to the change of 50Hz ~ 1,000Hz).

The AC high voltage generation circuit 51 is a circuit capable of generating a specific pulse waveform without applying an input signal from the outside, but there are many such circuits. The vibrator method is adopted.

FIG. 7 shows a single-sided, double-sided light emitting device by adding a rectifier 531, a base via voltage setting unit 532, and a constant voltage output unit 533 to the front end of the high frequency generation AC high voltage generation circuit 51 for DC power. The high frequency generation AC high voltage conversion circuit 51 for AC power supply for driving is comprised.

The operation of this circuit is that the AC power is rectified without ripple through the rectifying portion 531 composed of the diode D1, the resistor R2 and the capacitor C3, and the resistor R3 is the transistor Q2. It suppresses (Q3) within allowable power and protects against output short circuit.

In addition, the resistors R4 and R5 supply a bias voltage to the base of the transistor Q2, and when the transistor Q2 is driven, power is also supplied to the base of the transistor Q3, so that these two transistors Q2 and Q3 are provided. ) Constitutes an emitter follower circuit.

On the other hand, the resistor R6 and the zener diode ZD can compensate for the AC input fluctuations to obtain the required voltage, and the diode D2 has a forward current only when an AC voltage of 95 V or more is input. Flows, thereby preventing the current of the battery 6, which is operated at the time of power failure, from flowing backward.

At this time, the battery should use a rechargeable battery. When more than 95 volts is applied from the circuit, the circuit operates with an AC power source and continues to charge the battery.

However, when the AC power is cut off or the power failure is a basic circuit diagram in which power is supplied to the planar light source 2 by the batteries 6 connected in parallel so that the single-sided and double-sided light emitting devices continue to operate.

8 shows an auto-illumination circuit 52 for turning on / off a control target according to the brightness of light, and is a circuit in which cds whose resistance value changes according to the brightness of light is applied.

That is, when light is applied to the light sensing device Cds, the resistance value is lowered, so that the output voltage of the light sensing unit 521 is increased. In this case, the comparator U in the power supply control unit 523 is configured as the light sensing unit (Cds). When the output voltage of the light detector 521 is higher than the reference voltage, a high signal is output when the output voltage of the light detector 521 is higher than the reference voltage, and a low signal is output when the output voltage of the light detector 521 is higher than the reference voltage. ) Control the driving.

Therefore, the relay RL connected between the contact switch S1 between the battery 6 and the input terminal of the high voltage conversion circuit 51 is 'off' when the light is bright and 'on' when the light is less than the predetermined brightness so that the planar light source 2 Can be controlled ON / OFF.

The relationship is as shown in FIG.

That is, in the case of the double-sided transmission type light emitting device, it is possible to mount it on the front hood of various vehicles by using the fasteners 11 formed on the main body 1, and when the main body 1 is directly fixed on the hood, the appearance or fixing force Because of this deterioration, it was possible to fix it through the adapter 7 separately manufactured to have a structure that can be attached on the hood through the double-sided tape 71, which is almost the same as the configuration of the membrane installed in the existing vehicle.

In addition, in the case of the single-sided light emitting device, the double-sided tape 42 is simply attached and fixed to the trunk of the rear side, and then connected to the controller 5 through the connector 8.

On the other hand, the apparatus of the present invention can be installed on the front or rear of the vehicle by applying it to a membrane or a manufacturer's mark installed as an accessory of the vehicle, but as shown in Figs. Not only can it be applied, but it can also be applied to statues, sculptures, religious marks, etc. required by each religion, or can be applied as a dimming or a halo to a table or a frame.
