Referring to FIG. 1, in order to implement a lighting apparatus using both the wire dimming circuit 160 and the wireless dimming circuit 170, a board including each circuit must be separately manufactured. In addition, in the case of the conventional wired optical modulation circuit 160, since a complicated circuit using OP-AMP is used, there is a problem that a high cost and a large volume are forced due to the configuration.

Therefore, in order to solve the disadvantage of lowering the universality by invoking the increase in the unit price, there is a variety of lighting devices using a wired / wireless dimming integrated circuit that can prevent the enlargement and overcorrection of the components, .

BLE, Bluetooth dimming, etc.), and can implement a wired / wireless integrated dimmer circuit that selectively receives a wire dimming signal and a wireless dimming signal. A detailed description thereof will be made with reference to Figs. 2 to 5.

FIG. 2 is a configuration diagram showing a lighting control apparatus according to an embodiment of the present invention, and FIG. 3 is a configuration diagram showing a wired / wireless integrated lighting controller of a lighting control apparatus according to an embodiment of the present invention.

2 and 3, the lighting control apparatus of the present invention includes an input power unit 210, converters 230 and 240, an illumination unit 251, a wireless module 330, a wired module 310, a conversion module 350 ).

The input power supply unit 210 supplies the entire input power of the illumination device. In this case, it is preferable that the input power source to be input to the input power source unit 210 is a 220V commercial power source, and in the case of a 220V commercial power source, it may have a sine wave form that alternates periodically from -311V to + 311V. More specifically, the input power supply unit can serve as a power supply source for various devices used in the power supply unit.

Also, the EMI filter 220 may be further included in the input power section to remove noise from the input power source and apply the noise to the converter. When the input power is supplied from the input power source, electric noise changes into a magnetic field and electromagnetic interference (EMI) that interferes with other elements of the lighting control device may occur. Such noise can be removed by using an EMI filter.

Converters 230 and 240 convert the input power to the illumination power. The converter receives the main power and performs the power control function to convert and supply the stable and efficient power required by the system. In particular, the converter of the present invention can be implemented as an AC / DC converter (AC / DC converter) for converting an AC power source to a DC power source. In addition, a diode rectifier, a phase control rectifier, And various AC / DC conversion can be performed using a plurality of switches and a transformer.

In addition, the converter of the present invention may include a PFC converter 230 and a flyback converter 240. In particular, the flyback converter is an isolated SMPS circuit, which is electrically insulated from the line supplying the power, so that it can supply power to the output stage stably.

In addition, the converter of the present invention can receive the wireless dimming signal or the wire dimming signal and control dimming of the illuminating unit when the necessary driving condition is satisfied. More specifically, the flyback converter is a main block of the driving power supply of the LED lighting unit, and can control the dimming of the driving power supply of the LED lighting unit when the Vcc voltage and the necessary driving condition are satisfied.

The voltage for driving the converter of the present invention may be a general DC power source, but a standby module 271 for generating a voltage for driving the converter may be separately implemented.

The illumination unit 251 emits light when the lighting unit supply power is applied. The converter converts the input power to the illumination power supply and applies it. In particular, the illumination unit 251 of the present invention may be configured as a light emitting diode (LED). Light emitting diodes (LEDs) are semiconductor-based light sources and have various advantages such as low cost, long life, miniaturization, environment-friendly waste treatment, low energy consumption, high efficiency and linearity.

The dimmer inputs a dimming signal for controlling the illumination unit. Such a dimmer is a device for continuously varying the luminous intensity, illuminance or color of a lamp, and is capable of both wired operation and wireless operation (remote operation).

In particular, the dimmer of the present invention is characterized in that at least one of a 0-10V dimming signal, a 1-10V dimming signal, and a PWM dimming signal is input. The 0-10V dimming signal controls the voltage of the control line by varying from 0V to 10V, and the 1-10V dimming signal is controlled by varying from 1V to 10V. The PWM dimming signal is a method of adjusting the amount of current by modulating the width of the frequency for controlling the power supply. The dimmer of the present invention can also be used by inputting various dimming signals which can be generally used.

More specifically, the dimmer of the present invention may include a wireless module 330 for inputting a wireless dimming signal and a wired module 310 for inputting a wire dimming signal. In addition, the dimmer of the present invention can selectively receive a wireless dimming signal or a wire dimming signal. In particular, since the present invention is embodied to include a voltage application module in common, an error may occur in a lighting control device when receiving a wire dimming signal and a wireless dimming signal at the same time. Therefore, only one of a wireless dimming signal and a wire dimming signal Selectively. Therefore, the user or the manager can control the lighting device by selecting the wireless dimming or the wire dimming as required.

The conversion module 350 receives the wireless dimming signal or the wire dimming signal, converts it into a predetermined power source, and applies it to the converter. More specifically, the conversion module may receive the wireless dimming signal or the wire dimming signal to convert the one-block power supply into a two-block power supply. If a dimming signal is received and converted to an analog voltage (about 0.5V to 2V) by a voltage application module, the power of this value can not be applied to the power control device as it is, so it must be converted to a suitable value. Therefore, the power can be converted into a power source of 2 blocks through the conversion module and used for the converter and the power control device.

4 is a circuit diagram showing a wired / wireless integrated dimmer circuit of a lighting control apparatus according to an embodiment of the present invention.

Referring to FIG. 4, the configuration of the wireless module, the wired module, and the voltage application module receiving and selecting the dimming signal in the wired or wireless mode can be confirmed. In particular, the wireless module 330 and the wired module 310 may commonly include a voltage application module 340. The voltage application module operates both when receiving the wireless dimming signal or when receiving the wire dimming signal, and can apply the generated power to the conversion module.

The wireless module 330 inputs a wireless dimming signal to control the illumination unit. The wireless module of the present invention may include a power supply unit (+10 V), a wireless signal input unit 331, a first switch device 335 and Q1, a second switch device 338 and Q2, and a voltage application module 340 have. It further includes a first resistor 332, a first capacitor 334 and a zener diode 333, a second resistor 336 and a second capacitor 337, a third resistor 339 and a fourth resistor . At this time, the wireless module 330 preferably receives a PWM dimming signal.

The power supply unit inputs 10V power supply. Such a power supply can operate as a driving power source for the first switch element and the second switch element, and can be applied to the voltage application module to generate an analog voltage magnitude according to the duty cycle of the PWM signal. More specifically, the larger the PWM signal period, the larger the analog voltage magnitude, and the smaller the PWM signal period, the smaller the analog voltage magnitude.

The wireless signal input unit 331 receives the PWM dimming signal. If the PWM dimming signal is input with a period such as high-low-high-low, the signal can be converted by the first switch element and the second switch element.

The first switch element Q1 335 performs an on / off operation by applying a PWM dimming signal and the second switch element Q2 338 performs an operation opposite to the first switch element . At this time, the first switch element and the second switch element may be composed of at least one of FET, BJT, and SCR. Further, the rectangular-wave dimming signal generated by the second switching element is applied to the voltage application module and converted into an analog power supply.

More specifically, when the PWM dimming signal is high (H), a 3V signal is applied to connect the first switch element Q1 335. When the first switch element is turned on, the gate voltage of the second switch element becomes 0, and the drain-source of the second switch element becomes open. Therefore, the 10 V supply power of the power supply unit is directly applied to the voltage application module, resulting in 10 V.

When the PWM dimming signal is low (L), the 0V signal is applied so that the first switching elements Q1 and 335 are not connected. When the first switch element is turned off, the gate voltage of the second switch element is applied, and the drain-source of the second switch element is short-circuited. Therefore, since the 10 V power supply of the power supply unit exits to the short-circuited line, the magnitude of the power supplied to the voltage application module becomes 0 V.

The first resistors R1 and 332 are connected in series with the wireless signal input unit and serve as current control according to the PWM dimming signal. The first capacitor (C1, 334) is connected in parallel with the first resistor, and removes the noise of the input PWM dimming signal. The Zener diode 333 is connected in parallel with the first resistor, and performs a function of clamping when the applied voltage is above a certain level.

The second resistor (R2, 336) is connected in parallel with the output terminal of the first switch element, and controls the magnitude of the voltage applied to the second switch element. The second capacitor (C2, 337) is connected in parallel with the output terminal of the first switch element, and removes the noise of the signal generated by the first switch element.

The third resistors R3 and 339 are connected between the output terminal of the first switch element and the power supply unit, and apply a power supply (+10 V) to the first switch unit. The fourth resistor R4 is connected between the output terminal of the second switch element and the power supply, and divides the power supply of the power supply according to the size of the fifth resistor and the sixth resistor.

The voltage application module 340 is used for both the wireless module and the wired module, and converts the rectangular wave dimming circuit generated by the second switch element to analog power. The voltage application module 340 may include a fifth resistor R5 and 341, a sixth resistor R6 and 342, a third capacitor C3 and 343 and a fourth capacitor C4 and 344.

The fifth resistor (R5, 341) is connected in series with the output terminal of the second switch element, and the sixth resistor (R6, 342) is connected in parallel with the fifth resistor. The fifth resistor and the sixth resistor serve to adjust the magnitude of the power supply of the power supply with the fourth resistor.

The third capacitors C3 and 343 and the fourth capacitors C4 and 344 are connected in parallel with the fifth resistor to implement a smoothing circuit of the signal. The generated signal passing through the first switch and the second switch element may contain a ripple voltage in the direct current as compared with the inputted PWM dimming signal. Therefore, a smoothing circuit should be implemented to reduce such ripple.

The wired module 310 inputs a wired dimming signal for controlling the illumination unit. At this time, the wired module can receive the 0-10V dimming signal. The wired module may include a wired signal input unit 311, a line filter 312, a diode 313, and filters 314 and 315.

The wired signal input unit 311 receives the 0-10V dimming signal and applies it to the voltage module. Further, the line filter 312 removes the noise of the 0-10V dimming signal, and the filters 314 and 315 are also connected in series to remove the noise. The diode 313 prevents reverse bias voltage of the voltage application module. When a voltage is applied to the output, a reverse bias may be generated and the circuit itself may be destroyed, so that a diode can be included in the wire signal input portion to prevent this.

The voltage application module 340 is also used to input a wired signal and plays the same role as a wireless dimming signal. The fifth resistor and the sixth resistor adjust the magnitude of the supply voltage, and the third capacitor and the fourth capacitor serve as a smoothing circuit that removes the ripple voltage of the generated signal.

The embodiments of the present invention described above are disclosed for the purpose of illustration, and the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention.
