The present invention relates to lighting brightness control, and more particularly, to allow dimming (dimming) adjustment with all kinds of infrared remote controllers, and to the type of lamp (three-wavelength fluorescent lamp or incandescent bulb) inserted into the socket. According to the present invention, a dimming adjustment is selectively performed, and a lighting brightness adjusting device and a method for dimming stepwise or continuously according to a user's operation are provided.

In general, the power control (brightness control) of the illumination is performed by a passive element or by an operation by a dedicated remote controller.

The former method in which the user adjusts the power of the light by manual operation using the controller, is possible to continuously adjust the brightness, but the user is inconvenient to operate the controller directly.

The latter method of adjusting the brightness using a dedicated remote control is convenient because the remote control can be used. However, since a dedicated remote control using a standardized signal is used, a separate remote control must be provided separately. If you lose the disadvantage that you can not control the brightness using the remote control.

On the other hand, all the conventional lighting power adjustment method, the brightness of the voltage supplied to the lamp by varying the phase control or by controlling the brightness, in this case using a fixed dimming regulator according to the frequency and voltage of a specific commercial power supply Because of the adjustment, there is a problem that it is impossible to adjust dimming with one dimming regulator in all countries where the frequency and voltage of the commercial power source are different.

For example, South Korea's commercial power source uses AC 220V, frequency 60Hz, while Germany uses AC 110V, frequency 50Hz. In addition, many countries select and use one of the two commercial power sources according to their characteristics. Therefore, the conventional dimming regulator for controlling the lighting power, previously manufactured to correspond to the two commercial power, respectively, was used in accordance with the corresponding commercial power. As a result, this leads to the disadvantage that the dimming regulator has to be different depending on the commercial power source for the light dimming.

In addition, all the lighting power adjustment method using a conventional remote control, the brightness level is set in advance by several steps (for example, three to five steps), and the brightness is adjusted while changing the level through the remote control operation. This not only causes inconvenience to the user to operate the remote control several times, but also disadvantages that continuous dimming is impossible. For example, in a dimming controller in which the brightness level is implemented in steps 1 to 5, assuming that the current lighting level is brightness 1, if the user wants the brightness level to be brightness 5, the user may change the brightness control button of the remote control to at least 4 times must be pressed, and the dimming step by step is not natural compared to the continuous dimming has the disadvantage.

Figure 2 is a block diagram showing the configuration of the "light brightness control device" according to the present invention embedded in the socket, Figure 3 is a circuit diagram showing the configuration of the illumination brightness control device.

Here, reference numeral 110 denotes a rectifying unit for full-wave rectifying the supplied AC power AC to rectify with a predetermined DC voltage DC, and including Zener diodes D1 and D3, which are constant voltage diodes, and half-wave rectifying diodes D2 and D4. It is preferable to include the smoothing capacitor C2.

Reference numeral 120 is a power analysis unit for analyzing the supplied AC power (AC), a square wave for sensing the frequency and voltage of the commercial power supply by switching to the constant voltage provided from the zener diode (D1) of the rectifier 110 It is preferable to include a switching element (Q1) for outputting a and a smoothing capacitor (C3) for smoothing the square wave generated by the switching operation of the switching element (Q1).

Reference numeral 130 is an infrared sensor that receives an infrared signal transmitted from an external remote controller and outputs an illumination brightness control signal, and converts the infrared signal received through the light receiving window 31 in the light receiving unit 30 into a digital signal corresponding thereto. It plays a role.

Reference numeral 140 denotes a load detector for detecting a type of a load (lamp), and a voltage divider for dividing a voltage across both ends of the triac Z1, which is a component of the phase controller 160, which will be described later to determine the type of the lamp. It is preferable to include (R5) (R6).

Reference numeral 150 is a search for the output signal of the load detection unit 140, when the illumination brightness control signal is applied from the infrared sensor 130, and determines the type of load, and as a result of the determination if the load is the brightness control target power A control unit for generating a control signal for adjusting the illumination of the load according to the power analysis signal output from the analysis unit 120, a conventional micro controller unit (MCU: Micro Controller Unit).

Reference numeral 160 is a phase controller for controlling the phase of the power according to the control signal generated by the controller 150 to automatically adjust the brightness by varying the power supplied to the load, the phase control signal generated by the controller 150 In response to the switching element Q2 performing a switching operation, the collector terminal and the gate terminal of the switching element Q2 is connected, the triac (Z1) for controlling the phase of the power supplied to the lamp 170 It is preferable to include.

Referring to the operation of the illumination brightness control device according to the invention configured as described above are as follows.

When the AC power source 180 is supplied, the rectifying unit 110 rectifies the AC power supplied using the half-wave rectifying diodes D2 and D4 into a DC power source, and the smoothing capacitor C2 smoothes the rectified DC voltage. do.

The smoothed DC voltage (DC 5V) is supplied to the infrared sensor 130, the controller 150, and the phase controller 160 for driving. The controller 150 is activated when power is supplied to control the overall operation of the apparatus. do.

With the device activated, the user decides whether to adjust the brightness of the lamp 170 automatically or not. This determination determines whether or not to adjust the brightness by manipulating the light receiving portion 30 of the socket shown in FIG. 1. For example, when the user wants to adjust the illumination brightness, the light receiving window 31 of the rotatable light receiving unit 30 is positioned in a direction in which an infrared signal transmitted from the remote controller can be received. That is, as shown in FIG. 1A, the position of the light receiving window 31 is set to receive the most infrared signal. Here, the remote control is any remote control using an infrared signal (for example, a TV remote control, an audio remote control, an air conditioner remote control, etc.), and does not mean a dedicated remote control for the illumination brightness control device according to the present invention. In other words, in the present invention, all remote controllers capable of transmitting infrared rays may be used without using a dedicated remote controller.

Meanwhile, in a state where the light receiving window 31 is positioned as shown in FIG. 1A, when a user generates a specific operation signal with a TV-specific remote control for operating other devices (eg, TVs) other than lighting, the light receiving window ( 31) an infrared signal is received.

In addition, in the state where the light receiving window 31 is positioned as shown in FIG. 1B, an infrared signal is received only when the infrared emitting direction is intentionally matched to the light receiving window 31.

On the contrary, if the user operates the light receiver 30 so that the light receiver window 31 is not visible when viewed from the front of its current position as shown in FIG. 1C, the infrared light signal is actually received by the light receiver window 31 even when the remote controller is operated. Since no light is received, no adjustment of the illumination brightness occurs.

Therefore, the user determines whether or not to adjust the brightness of the lighting according to his intention, and correspondingly only by changing the position of the light receiving window 31, the control of the illumination brightness is made.

If the brightness of the lighting is not controlled and the direction of the light receiving window 31 is set as shown in FIG. 1C, no infrared signal is received by the infrared sensor 130 during remote control operation. It will not go crazy.

However, if it is assumed that the brightness of the lighting is adjusted, and the direction of the light receiving window 31 is set as shown in FIG. 1A or 1B, an infrared signal may be received or received by the infrared sensor 130 according to the user's remote control operation direction. It may not be. Assuming that an infrared signal has been received, the infrared sensor 130 converts the received infrared signal into an electrical signal, converts the received infrared signal into a digital signal, and provides the converted signal to the controller 150.

When the illumination brightness control signal is provided, the controller 150 analyzes the output signal of the load sensor 140 to determine whether the connected lamp 170 is an incandescent bulb or a three-wavelength fluorescent lamp.

Whether the connected lamp is an incandescent bulb or a three-wavelength fluorescent lamp, the load sensing unit 140 measures the voltage across the triac Z1 in the phase control unit 160 with the voltage divider R5 and R6, and the capacitor C4. By providing the control unit 150 by smoothing the control unit 150, the control unit 150 can easily recognize the type of the connected lamp. For example, the controller 150 sets a reference value for determining the type of lamp, compares the detection value provided by the load detector 140 with the reference value, and determines the type of lamp connected in large or small sizes. Will print.

As a result of recognizing the type of lamp, when the connected lamp is a three-wavelength fluorescent lamp (electron collision type lamp), the controller 150 does not perform an illumination brightness adjustment operation. In the case of a three-wavelength fluorescent lamp, the dimming function by the phase control has an adverse effect on the internal circuit. Therefore, the dimming function is not performed when the connected lamp is a three wavelength fluorescent lamp.

Next, as a result of recognizing the type of lamp, when the connected lamp is an incandescent bulb, the frequency and voltage level of the power supplied to the power analysis value provided by the power analyzer 120 are recognized. Here, as shown in FIG. 3, the power analyzer 120 performs a switching operation with the voltage through the zener diode D1 in the rectifier 110, and switches the switching element Q1 to the switching element Q1. Accordingly, the voltage generated at the collector terminal is smoothed by the smoothing capacitor C3 and provided to the controller 150 as a power analysis value. The power analysis value provided here is a square wave digital signal.

The controller 150 detects the provided square wave digital signal to detect the frequency and voltage level of the power supply, and applies the phase control signal to the phase controller 160 according to the detected frequency and voltage level.

The phase controller 160 controls the phase of the power supplied to the lamp 170 in response to the applied phase control signal. The power control is changed by the phase control so that the brightness of the lamp 170 is changed.

Meanwhile, the controller 150 selectively performs dimming types, that is, stepwise brightness adjustment and continuous brightness adjustment, when controlling the illumination brightness. This may be determined by searching the illumination brightness control signal provided from the infrared sensor 130, whether it is a step-by-step brightness control or a continuous brightness control. For example, by searching the period of the infrared signal provided from the infrared sensor 130, if the infrared signal is continuously provided, it is determined by the continuous dimming, and correspondingly to control the phase continuously, otherwise When the infrared signal is provided at a fixed interval or once or a very small number of times, phase dimming is used to perform phase control step by step.

Here, in the case of dimming step by step, the brightness of the light is brightened step by step. In the case of continuous dimming, the light brightness is continuously brightened.

Phase dimming requires only one phase control of the phase, but continuous dimming requires continuous phase control. Therefore, in the case of continuous dimming, the light becomes brighter and the dimming operation is stopped at the timing when the user who performs the brightness control does not operate the remote controller in a desired light brightness state.

Figure 4 is a flow chart showing the "light brightness control method" according to the present invention, S represents a step (Step).

As shown in the drawing, the illumination brightness control method includes: determining a type of load by a signal provided from the load sensing unit 140 when an illumination brightness control signal is received (S101 to S103); Recognizing a three-wavelength fluorescent lamp and disregarding the received illumination brightness control signal when the type of load is not the brightness adjustment target (S107, S109); Determining the dimming type by analyzing the received illumination brightness control signal when the type of load is a brightness control target (S111); If the dimming type is dimming according to the determination result, determining the frequency and the voltage through power analysis, and then performing phase control corresponding thereto to adjust brightness through dimming step (S113 and S115); If the dimming type is a continuous dimming result, the frequency and voltage are determined through power analysis, and phase control is performed accordingly to adjust brightness by successive dimming (S117 to S121).

In the method of adjusting the brightness of light according to the present invention as described above, when the brightness brightness control signal is received in step S101, in order to detect the type of the lamp (load) connected in step S103, the triac Z1 in the phase controller 160 is detected. Both voltages are detected.

Next, in step S105, the detected voltage is searched to determine whether the connected lamp is an incandescent lamp. If the connected lamp is not an incandescent lamp as a result of the determination, the process moves to step S107 to recognize a three-wavelength fluorescent lamp, and then to step S109. It will not move and perform light brightness adjustment.

On the other hand, if the connected lamp is an incandescent lamp, go to step S111 to determine the type of dimming. As a result of this determination, if the dimming type is dimming step-by-step, go to step S113 to detect the frequency and voltage level of the input commercial power supply and perform power analysis.In step S115, the illumination brightness is adjusted through stepwise phase control corresponding to the analysis result. Will be

On the other hand, if the step is not dimming, go to step S117 to see if it is a continuous dimming, and if the result of the check is a continuous dimming, go to step S119 and detect the frequency and voltage level of the commercial power input to analyze the power. . The brightness of the illumination is adjusted through continuous phase control in step S121 based on the power analysis result.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

According to the present invention described above, there is an advantage that can be dimmed (dimming) with any kind of infrared remote controller (Remote Controller) other than the dedicated remote controller applied to the illumination brightness control device.

In addition, there is an advantage that can be selectively adjusted dimming according to the type of lamp (three-wavelength fluorescent lamp or incandescent bulb) inserted into the socket.

In addition, there is an advantage that can automatically perform step or continuous dimming according to the user's operation.
