Description

Apparatus for Generating Control Power Source and Apparatus for Lighting Control of Light Emitting Device Using Same}

An embodiment of the present invention relates to a control power generator and a light emitting device lighting control apparatus using the same. More particularly, the present invention relates to a control power generating device for reducing heat generation and reducing power consumption by controlling a current of a control circuit generating a control power, and a light emitting device lighting control device using the same.

LED (Light Emitting Device) lighting is a trend that is widely used in the lighting field to save energy due to high efficiency.

In order to drive the LED, a driving circuit that supplies a constant current to match the characteristics of the LED is required. In addition, in order to control the amount of light generated from the LED, that is, illuminance, the current flowing to the LED must be controlled.

1 is a diagram illustrating an example of a control power generation circuit.

As shown in Fig. 1, the rectified phase control power is supplied to the power input. Phase controlled AC power is usually obtained by phase controlling the AC power with a triac. Phase control AC power is turned on when it is applied in incandescent lamp and illuminance is adjusted by controlling the phase.

The rectified phase control power supply is obtained by rectifying the phase control AC power supply.

When the width of the turn-on period of the rectified phase control power supply is β and the minimum value is β _min , the illuminance becomes minimum when β is β _min and the illuminance increases as β increases.

In general, the LED is driven through the current control circuit without applying the rectified phase control power.

The circuit of Fig. 1 is used to obtain a control power supply for the LED driving circuit. That is, the function turns on the current control circuit if the waveform exists in the rectified phase control power supply and turns off the current control circuit if the waveform does not exist in the rectified phase control power supply.

The conventional method shown in FIG. 1 uses a series stabilized power supply circuit composed of FET1, R1, ZD1, and C1 after rectifying the waveform of the phase controlled AC power source. C1 maintains the voltage of ZD1 minus the turn-on voltage of FET1.When the voltage of C1 decreases, a large amount of current is supplied through FET1 so that the voltage is maintained at a desired value, and when the voltage of C1 increases, the current flowing through FET1. So that the voltage is kept at the desired value.

FIG. 2 is a graph showing the waveform of the rectified phase control power supply (= drain voltage of FET1), the current of FET1, and the voltage of C1 in the circuit of FIG.

When the drain voltage of FET1 shows a waveform as shown in Fig. 2A, as shown in Fig. 2B, the current of FET1 does not flow over the entire period of β but only in a very short interval. This is because C1 is charged at the beginning of the β period, and the voltage of C1 increases. However, the section in which the current of FET1 flows is the section in which the voltage of the FET1 drain is high. The high voltage of the drain of FET1 occurs as a loss in FET1 except for the voltage of C1, causing a problem of high power loss and heat generation.

The embodiment of the present invention senses the rectified phase control power input to generate a control power to control the current to reduce heat generation and reduce power consumption.

3 is a diagram illustrating a control power generator 300 according to a first embodiment of the present invention.

As shown in FIG. 3, the control power generator according to the first embodiment of the present invention includes a first resistor R1, a second resistor R2, a third resistor R3, and a fourth resistor R4. FET1), zener diode ZD1, second transistor Q2, and capacitor C1.

In FIG. 3, one end of the first resistor R1 and the drain D1 of the first FET FET1 are connected in parallel to one end of the rectified phase control power supply, and the other end of the first resistor R1 is disposed in parallel. It is connected in parallel to the gate of the 1FET (FET1) and the collector (C2) of the second transistor (Q2), and to the source (S1) of the first FET (FET1) of the zener diode (ZD1) -second resistor (R2) series circuit One end is connected in parallel with one end of the capacitor C1, and the other end of the zener diode (ZD1) -second resistor (R2) series circuit is connected to the base (B2) and the third resistor (2) of the second transistor (Q2). Connected in parallel with one end of R3), and connected in parallel with the other end of the third resistor R3 and the other end of the capacitor C1 to one end of the fourth resistor R4, and the other end of the rectified phase control power supply. The other ends of the emitter E2 and the fourth resistor R4 of the second transistor Q2 are connected in parallel, and control power is detected at both ends of the capacitor C1. Here, the positions of the zener diodes ZD1 and the second resistor R2 may be interchanged.

4 illustrates waveforms of the phase control power supply (= drain voltage of FET1) rectified in the circuit of FIG. 3 (FIG. 4A), current of first FET (FET1) (FIG. 4B), and voltage of capacitor C1 (FIG. 4C). It is a graph shown.

In Fig. 4, FET1 is operated as a constant current circuit. FET1 operates as a constant current circuit by sensing the current flowing through FET1 at R4 and controlling the gate of FET1 through Q2. The current flowing through FET1 depends on the voltage of C1. The voltage at C1 is equal to the sum of the voltages at ZD1, R2 and R3. If the voltage of C1 is greater than the voltage of ZD1, the larger one is divided into R2 and R3. Therefore, if a large voltage is applied to R3, even if a little voltage is generated in R4, Q2 is operated to lower the gate voltage of FET1 so that the current of FET1 flows less. On the contrary, if the voltage is applied to R3 small, Q2 is operated when more voltage is applied to R4 so that the current of FET1 flows much.

Although the voltage of C1 has some ripple component but is continuous, the voltage on R3 also varies, but it is continuous without breaking every waveform. Therefore, the voltage across R4 is about 0.6V of the base-emitter operating voltage of Q2 minus the voltage of R3, and the current flowing through FET1 is divided by R4. Since the voltage becomes almost constant over the entire sine wave, the current flowing through the FET1 flows almost uniformly throughout the β section where the voltage is present in the drain of the FET1.

Comparing FIGS. 2 and 4, the average current of FET1 is the same as the output current, but in FIG. 4, the current of FET1 flows uniformly over all sections of β, whereas in FIG. 2, the current of FET1 is concentrated in the initial section of β. have.

Therefore, the loss in FET1 becomes drain-source voltage x drain (or source) current, so that the loss of current flows at a lower drain voltage is much less than that at a high drain voltage. Therefore, since the control power generating device of the present invention flows in FET1 even at a low drain voltage as shown in FIG. 4, less heat is generated and power is consumed than in the case of FIG. 2 where the current is concentrated at a high drain voltage. Is less.

Meanwhile, a phase width detection circuit may be further connected between one end of the rectified phase control power supply and the drain D1 of the first FET FET1. In addition, a photocoupler may be used as the phase width detection circuit and detects the phase width β of the rectified phase control power supply. In the present invention, the phase width detection circuit is not limited to the photocoupler.

FIG. 5 is a diagram illustrating a control power generator 500 when the photocoupler PC1 is connected to the phase width detection circuit.

Unlike the circuit of FIG. 1, the circuit of FIG. 3 connects a circuit (that is, PC1) that detects the phase width β of the rectified phase control power supply because the current of FET1 flows for the entire period of β, as shown in FIG. 5. By configuring, the phase width β can also be detected. Here, PC1 may detect a phase width β section of the phase control power source rectified as a photocoupler.

One end of the resistor R4 is connected in parallel, the other end of the fourth resistor R4 is connected in parallel with one end of the third resistor R3 and one end of the capacitor C1, and the second transistor Q2. Emitter (E2) is connected to the emitter (E3) of the third transistor (Q3), the base B3 of the third transistor (Q3) is the other end of the third resistor (R3) and the second resistor ( R3)-Zener diode (ZD1) is connected in parallel with one end of the series circuit, the other end of the rectified phase control power supply and the other end of the capacitor (C1) and the second resistor (R2)-Zener diode (ZD1) series circuit Is connected in parallel with the other end of and controlled at both ends of the capacitor (C1) The power supply (ie, the C1 voltage) is detected.
