  FIG. 4 is a block diagram of functions of the light control apparatus according to the embodiment of the present invention. As shown in FIG. 4, the light control device 200 includes a touch sensor module 230, an indicator light module 240, a microprocessor 250, a power conversion circuit 260, a power phase control circuit 270, a photocoupler (photo coupler). coupler) 280. The cover 220 may have a structure in which a plastic plate is provided on a printed circuit board, and all the electronic elements are connected to circuits on the cover 220, and the covers 220 are connected to each other. A part of the electronic element is provided on the front surface of the cover 220, and a part of the electronic element is located on the back surface of the cover 220 and in the case 210. In the embodiment, the touch sensor module 230 is provided on the front surface of the cover 220. In the present invention, those having ordinary knowledge can arrange the electronic elements based on the design of the product, so that the details of the arrangement method will be omitted below.

  The power conversion circuit 260 converts an external AC power supply AC to a DC power supply DC, and is connected to the microprocessor 250 to send a DC power supply DC of about 5 V and a phase sensing signal Ps to the microprocessor 250. . The microprocessor 250 is connected to the touch sensor module 230, and outputs the light intensity control signal Lcs and the instruction control signal Ics based on the touch signal detected by the touch sensor module 230.

  In this embodiment, in order to protect the microprocessor 250, the photocoupler 280 is connected between the microprocessor 250 and the power supply phase control circuit 270. The microprocessor 250 transmits the light intensity control signal Lcs to the power phase control circuit 270 through the photocoupler 280.

  The external lamp 400 is connected to the live line (Live) and the neutral line (Neutral) of the AC power supply AC through the power phase control circuit 270 of the light control device 200. The power phase control circuit 270 receives the light intensity control signal Lcs from the microprocessor 250 and controls the light intensity of the lamp 400 based on the light intensity control signal Lcs. The indicator light module 240 has a plurality of light emitting diode elements (LEDs), and informs the user of the current light intensity value state of the electric lamp 400. The indicator light module 240 receives the instruction control signal Ics of the microprocessor 250, and further activates the associated light emitting diode element and adjusts the luminous intensity of the associated light emitting diode element based on the instruction control signal Ics.

  In this embodiment, the touch sensor module 230 includes a first touch sensor 231 and a second touch sensor 232, and each of the touch sensors may be a capacitor type touch sensor. Further, the example here will be described on the assumption that the indicator light module 240 has five light emitting diode elements (first LED 241 to fifth LED 245). When the light control device 200 and the glass plate 300 are assembled, the position of the first touch sensor 231 corresponds to the position of the first touch area 331 and the position of the second touch sensor 232 corresponds to the position of the second touch area 332. The position of the indicator light module 240 corresponds to the position of the indicator light area 333. Accordingly, when the user touches the first touch area 331 and the second touch area 332, the first touch sensor 231 and the second touch sensor 232 detect that they are touched and output a touch signal. It should be noted here that the term “A touched B” means “A touches B”, “A is adjacent to B”, “A is in the vicinity of B” or these touch sensors Includes a case where a touch signal can be output.

  FIG. 5 is a flowchart of the write control method according to the embodiment of the present invention. As shown in FIG. 5, the microprocessor 250 determines the touch state of the touch sensor module 230 based on the touch signal detected by the touch sensor module 230.

  When it is detected that both the first touch sensor 231 and the second touch sensor 232 are touched, the power supply phase control circuit 270 activates the lamp 400 based on the lamp luminous intensity value stored in the register 251, and the luminous intensity of the lamp 400 Is adjusted to the stored light intensity value. The indicator light module 240 activates the related LED and adjusts the light intensity of the related LED based on the stored electric light intensity value.

  More specifically, the microprocessor 250 generates a light intensity control signal Lcs and an instruction control signal Ics indicating the stored light intensity value based on the stored light intensity value, and determines related LEDs. The power phase control circuit 270 receives the light intensity control signal Lcs indicating the stored lamp light intensity value via the photocoupler 280, starts the lamp 400, and changes the light intensity of the lamp 400 to the stored lamp light intensity value. adjust. The indicator light module 240 activates the related LED and adjusts the luminous intensity of the related LED based on the instruction control signal Ics indicating the stored electric light intensity value. In an embodiment, the number of the LEDs shining and the luminous intensity of the lamp 400 are directly proportional. For example, when the lamp 400 is turned off, the first LED 241 is activated, and when the lamp 400 has the maximum (100%) luminous intensity, the first LED 241 to the fifth LED 245 are activated. Further, when the lamp 400 has a luminous intensity of 60%, the first LED 241 to the third LED 243 are activated. The light intensity of the first LED 241> the light intensity of the second LED 242> the light intensity of the third LED 243 causes the light intensity of the LED to exhibit a state of gradation. Further, when neither the first touch sensor 231 nor the second touch sensor 232 detects a touch within 10 seconds, the light intensity of the LED is darkened.

  As described above, the microprocessor 250 described in detail the method for controlling the power supply phase control circuit 270 and the touch sensor module 230 using the light intensity control signal Lcs and the instruction control signal Ics. Therefore, in the following description, details of similar steps are omitted.

  Referring again to FIG. 5, if it is detected that only the first touch sensor 231 has been touched and the touched time is less than 1 second (first predetermined touch time), the microprocessor 250 determines the power phase control circuit. 270 is instructed to gradually brighten the lamp 400 within 2 seconds (second predetermined time), and based on the light intensity value of the lamp 400, the related LED is activated to adjust the brightness of the related LED. Request to the indicator light module 240. In this embodiment, the light 400 is gradually brightened in less than 2 seconds to make the user feel a change in the light intensity of the light 400. In another embodiment, the second predetermined time can be set to substantially 0 seconds.

  When it is detected that only the first touch sensor 231 is touched and the touch time is 1 second (first predetermined touch time) or more, the microprocessor 250 turns on the power phase control circuit 270 based on the touch time. Instruct to increase the luminous intensity of 400. Next, the adjusted light intensity value is stored in the register 251. Finally, based on the light intensity value of the lamp 400, the microprocessor 250 activates the associated LED and requests the indicator light module 240 to adjust the intensity of the associated LED.

  When it is detected that only the second touch sensor 232 is touched and the touch time is less than 1 second (third touch time). The microprocessor 250 instructs the power supply phase control circuit 270 to gradually darken the lamp 400 within 3 seconds (fourth predetermined time), and activates the associated LED based on the light intensity value of the lamp 400. Requests the indicator light module 240 to adjust the light intensity. More specifically, at this time, the lamp 400 is in an OFF state and its luminous intensity value is 0. Therefore, the first LED 241 is activated to inform the user of the position of the light control module 100. In the present embodiment, the reason why the lamp 400 is gradually darkened within 3 seconds is to make the user feel a change in the luminous intensity of the lamp 400.

  When it is detected that only the second touch sensor 232 is touched and the touch time is 1 second (third predetermined touch time) or more, the microprocessor 250 dims the light intensity of the lamp 400 based on the touch time. The power phase control circuit 270 is instructed as follows. Next, the adjusted light intensity value is stored in the register 251. Finally, the microprocessor 250 activates the associated LED based on the intensity value of the lamp 400 and requests the indicator light module 240 to adjust the intensity of the associated LED.

  If the first touch sensor 231 and the second touch sensor 232 do not detect that both are touched within 10 seconds (delay period), the microprocessor 250 darkens the light intensity of the related LED to the light intensity value of the energy saving mode. Request to the indicator light module 240. Since the indicator light module 240 is switched to the energy saving mode, electricity can be saved.

  FIG. 6 is a flowchart of the write control method according to the embodiment of the present invention. In this embodiment, only the switch control of the electric light 400 may be performed without performing dimming control. In this embodiment, one electric light can be controlled by one touch area and a touch sensor. Hereinafter, an example in which the electric lamp 400 is controlled by the first touch area 331 and the first touch sensor 231 will be described.

  As shown in FIG. 6, when the first touch sensor 231 detects touch, the microprocessor 250 instructs the power supply phase control circuit 270 to perform toggle switch control. That is, when the lamp 400 is OFF, the lamp 400 is turned on, and when the lamp 400 is ON, the lamp 400 is turned off.

  Next, it is determined whether or not the lamp 400 is in an ON state. If it is ON, the indicator light module 240 is turned off. If it is in the OFF state, it is determined again whether or not it is a change from ON to OFF (on / off transition). If so, an instruction is given under the circumstances within the delay period of 10 seconds. The light module 240 is activated, and under the condition of a delay period of 10 seconds or more, the light intensity of the LED of the indicator light module 240 is dimmed.

  As described above, according to the light control module 100 of the embodiment of the present invention, the glass flat plate 300 can be easily and easily exchanged according to the pattern and color of the wall. In the embodiment, when the light control module 100 is cleaned, the cleaning liquid does not enter the circuits and electronic elements on the cover 220, so that the light control module 100 is less likely to be damaged. In the embodiment, the light control device 200 can return to the previously stored light intensity value based on the user's habits, thereby simplifying the step of starting the light 400 by the user. Further, even if the user does not touch the touch area, the touch sensor can detect that the touch sensor has been touched. Therefore, when the light control module 100 is used in a hospital, the embodiment of the present invention has an advantage of preventing infectious diseases.

  As described above, the present invention has disclosed the best mode as an embodiment, but this is not intended to limit the present invention, and those skilled in the art can make various modifications without departing from the gist of the present invention. . Therefore, the scope of protection of the present invention is based on what is defined in the claims.
