The present invention relates to a circuit diagram of a digital strobe of a device that generates a high pressure when taking photographs of impressions and commercial photographs to discharge a strobe flash tube (FLASH TUBE) to use instant flash.

That is, a circuit diagram that can control the amount of light of the instantaneous flash by the method of determining the appropriate exposure since the picture is only taken when the exposure is appropriate to the camera film according to the surrounding environment or the subject when taking a picture. to be.

The conventional strobe has little variation in the amount of light, so it is impossible to replace the main light with an overexposure of the light by using the auxiliary light or the auxiliary light by BACK light according to the surrounding environment or subject, and it is placed depending on the position when taking a picture. There are inconveniences of using the STROBO separately for daylight supplementary backs or by adjusting the distance to the subject.

In the circuit configuration, the positive DC charging voltage control circuit is composed of a resistor and a relay triac, and the negative DC charging voltage is charged according to the positive DC voltage. The voltage is different and the amount of light is not constant. When the triac defect occurs, the battery continues to be charged, but there is no overvoltage charge prevention circuit, which is a very dangerous device, due to explosion of the photo denial capacitor (PHOTO CAPACITOR).

These days, natural expressions and expressions are pursued as photographic arts. Therefore, capturing moments is important for restlessly moving facial expressions such as children's photographs in commercial photography. However, conventional stroboscopic is not suitable for fast shooting due to the long charging time. However, there is no device for visually checking the strobe charging completion indicator so that the photographer can keep an eye on the subject and concentrate on the task.

The most important part of STROBO is the discharge tube (FLASH TUBE), which has different characteristics depending on the product and needs to be removable to replace according to the taste of the photographer. Even though it should be well managed, it is impossible for the conventional product to be fixed so that general users can follow up.

The control part of the product is made of variable resistor and switch, so the variable width of the charging voltage is different even in the same product.

The effect of the picture varies depending on the texture of the subject or the surrounding environment, so if you can see the effect of the strobe light or the light hitting the subject by movement, you will be able to improve your work efficiency.

Referring to the effect of the present invention as described above is as follows.

When AC power (AC / 110V-220V) is applied, power is supplied to the 110V / 220V automatic switching circuit 5 by the resistor R47 through the power switch PS2 and the fuse F1. The transistor Q9 does not operate due to the insufficient voltage applied to the gate divided by the resistors R46 and R65, and the escal SCR2 is operated by the voltage divided by the resistors R66 and R67 to activate the relay K2. ) Is switched and connected to the terminal 2 of the power transformer TR1 to apply power to the primary side, and the relays K2-S1, K2-S2, and K2-S3 are also switched together to be positive (-). The triple back pressure rectifying circuit 6 is operated to switch to the resistance R79 of the modeling lamp unit 10.

In the AC power supply 220V, the transistor Q9 is operated by the voltage of the gate divided by the resistors R46 and R65 to dissipate the divided voltages of the resistors R66 and R67 so that the escal SCR2 does not operate. The relay K2 is not switched and is connected to the terminal 3 of the power transformer TR1 so that the relays K2-S1, K2-S2, and K2-S3 are not switched and are positive. The double back rectifier circuit 7 is operated and is converted to the resistor R78 of the modeling lamp unit 10. In this way, the stroboscope devised an automatic switching circuit according to the input power supply (AC 100V / 220V) to automatically select the input power supply, and to automatically select the modeling lamp (LP1) and the positive and negative voltage rectifying parts (6, 7). In the circuit, in order to have 100% charging efficiency, the triple back voltage rectifier circuit is selected at 110V, and the double back voltage rectifier circuit is automatically selected at 220V, regardless of AC input power.

The AC power induced on the secondary side of the power transformer TR1 is applied to the bridge diode BD1 to form the constant voltage (8V) in the configuration of the smoothing condensation (C7) and the zener diode (ZD2). The non-inverting terminal (+) of the comparator (OP9) is separated to the HI level by the resistors R50 and R34, and the LO level is caused by the condensation (C14) when instantaneous glare is applied to the phototransistor (PT1). When the voltage is lower than the divided voltage of the inverting terminal (-) by the resistors R51 and R48, the output of the comparator OP9 becomes the LO level, so that the photocoupler PT2 connected to the select side through the transistor Q9 is connected. Wireless tuning is achieved by controlling, and it is composed of diodes D20 and D21 and condense C21 and C22 to perform wired tuning through the connector JP1, which is an external connection terminal, and the switch S1 can perform test tuning. .

The wired / wireless tuning signal is input to the end gate U3C through the photo coupler PT2, and another input terminal of the end gate U3C is the positive DC charging voltage sense of the comparator OP2 and the comparator OP8. When the negative DC charging voltage detection signal is input to the end gate (U3A) and fully charged, the output becomes HI level and is input to the end gate (U3C), so that the end gate (U3C) is fully charged. Only when the wired / wireless tuning signal comes in, it becomes HI level, is inverted by invert U1B and input to timer U2, and is always constant by the time constant of timer U2 and resistor R38 condense C11. The pulse signal is output and transmitted to the high voltage generator 9 and inverted by the invert U1E and input to the end gates U3B and U3D, respectively.

In this way, when taking pictures using multiple strobes, if you synchronize with one Taiwan wire, the light is synchronized at the same time.

The inverting terminal (-) of the comparator OP1 is input from the charging reference voltage generator 11 and the positive charging voltage (PTCAP + V) is divided into the resistors R1 and R36 at the non-inverting terminal (+).

The DC voltage charging is paused to prevent afterimages in the discharge tube X1.

When the charge signal reaches the HI level, the transistor Q1 is turned on, and the light emitting diode LED1 on the collector side can be confirmed that the eye is charging. The triac T1 is turned on through the photocoupler PT2 to supply AC power. In the case of AC110V, the contact (ac) of relay (K2-S2) is connected and positively connected to photocondensation (PTC1-PTC3) from a triple voltage rectifier circuit composed of current limiting cement resistors R74 and R75. When the positive DC voltage is charged and the AC power is AC220V, the contact (ab) of the relay (K2-S2) is connected and is connected from the double voltage rectifier circuit configured through the current limiting cement resistors (R42, R71).

The output is inverted by the invert U1D and input to another input terminal of the end gate U3A so that the end gate U3B is charged with negative DC voltage when the discharge tube X1 is discharged by the tuning signal. Is temporarily stopped to prevent afterimages in the discharge tube X1.

When the charging signal reaches the HI level, the transistor Q3 is turned on, and the light emitting diode LED3 on the collector side can be confirmed that the eye is charging. The triac T2 is turned on through the photocoupler PT3 and the AC power source is turned on. In case of AC110V, contact (ac) of relay (K2-S3) is connected to negative photocondensation (PTC4-PTC6) from triple voltage rectifier circuit composed of cement resistor (R76, R77) for current limiting. When the DC voltage is charged and the AC power is AC 220V, the contact (ab) of the relay (K2-S3) is connected and the current is limited from the double-voltage rectifier circuit configured through the cement resistors R69 and R70. The photocondensation (PTC4-PTC6) is charged with a negative DC voltage.

The signals of the positive voltage overcharge detection of the comparator OP3 and the negative voltage overcharge detection circuit of the comparator OP4 are terminated through the composite gate U4 and invert U1F to turn on the transistor Q4. AC power applied to the triacs T1 and T2 is cut off by the relay K1 connected to the collector side, thereby preventing the explosion of the photocondensation PT1-PT6 due to overcharging.

When the AC power is applied, the diode D17 is half-wave rectified through the current limiting resistor R43 condense C20, charged to the condensed C19, connected to the discharge tube anode A, and the backflow preventing diode D18.

The transistor Q7 is turned on, and the capacitor condensed when the escalal SCR1 is operated by applying a constant voltage from the zener diode ZD1 to the gate of the escalal SCR1 through the photocoupler PT1 on the collector side. The high voltage is generated in the trigger coil TG1 through the C13 and is applied to the terminal T of the discharge tube X1 to be discharged.

The charging reference voltage generator 11 is configured because it is applied to the positive (+) charge voltage control unit (1) (3) through a resistor to the output terminal.

The binary signal of the up-down counter U5 is level-converted by the non-inverting buffers U11A-U11D and applied to the decode U4. The output is input to the modeling lamp light amount control unit 15 and the memory chip U3, respectively. A binary signal is applied to each of the input terminals of the segment drives U1 and U2 by a program input to the memory chip U3, and the output signal is output through the current limiting resistor to display elements FND2, FND3, and FND4. ), The number corresponding to the binary signal is displayed.

The contact ab is connected to the photocoupler PT14 through the resistor R78, and the photocoupler PT14 is controlled by the flip-flop U14A and the transistors Q15 and Q21 by the contact of the switch S3. Then, the modeling lamp LP1 is turned on / off, and the power is varied by the resistors R94-R107 so that the photo coupler PT1-PT11 selected by the control signal of the decoder U4 is turned on. .

When discharging, the modeling lamp LP1 can be reversely driven to select the on / off tuning of the model lamp, and applied to the gate of the triac T3 through the diaak DA1 to control the brightness of the modeling lamp to control the variation of the discharge capacity. Accordingly, the brightness of the modeling lamp LP1 is also varied so that the body light reaching the subject can be seen, so that the final result can be known in advance, thereby improving work efficiency.
