The specific configuration of the user input unit 400 and the user input method will be described in detail with reference to FIG. 3, and a detailed description thereof will be omitted here.

The device control unit 500 is a component for controlling various components of the smart LED lighting apparatus 1000 and processing various data according to an embodiment of the present invention and includes a central processing unit such as a microprocessor ≪ / RTI >

The device control unit 500 controls the LED lighting apparatus 1000 to be driven in an operation mode set corresponding to a combination of ON and OFF states of a plurality of switches constituting the power switch unit 100 . Particularly, when the power switch unit 100 includes the first switch 110 and the second switch 120, the device controller 500 controls the operation of at least one of the first switch 110 and the second switch 120 The automatic power saving mode, the manual dimming mode, and the manual dimming mode, which are set in accordance with the determined state of the power switch unit 100, It is possible to control the LED lighting apparatus 1000 to be driven in any one of the general lighting modes.

First, when the power switch unit 100 enters the first state, the device control unit 500 may cause the LED lighting apparatus 1000 to be driven in the automatic power saving mode. Here, the automatic power saving mode is a mode in which the LED lighting unit 200 is automatically turned on, off, or adjusted in brightness according to a sensing signal generated through illumination or motion sensing of the interior of the sensor unit 300, This is a mode suitable for the case where the LED lighting apparatus 1000 is desired to be automatically turned on when power is restored to the room after long time absence or dark for the purpose of crime prevention, or when power saving is desired. In this case, the automatic power saving mode may be operated in a different manner depending on the type of the sensing signal transmitted to the device controller 500 through the sensing of the sensor unit 300. [

Specifically, when the power switch unit 100 is in the first state, the device control unit 500 causes the LED illumination unit 200 to light up or emit light with a preset first light intensity value, The LED illumination unit 200 is turned off or the brightness of the LED illumination unit 200 is set to a minimum value lower than the first brightness level And if the movement of the room is sensed again, the LED lighting unit 200 may be configured to re-illuminate the LED lighting unit 200 with the first luminance value.

If the sensing unit 300 senses the illuminance of the room and transmits an illuminance sensing signal in the first state of the power switch unit 100, the apparatus controller 500 may compare the illuminance measured with the predetermined reference illuminance value The LED illumination unit 200 may be configured to perform at least one of lighting, extinction, and brightness adjustment. According to the embodiment, the sensor for sensing the illuminance is installed outside the room where the LED lighting apparatus 1000 is installed, and if the measured external illuminance is lower than the reference illuminance value, the LED illuminating unit 200 illuminates the first luminous intensity value The LED illumination unit 200 is turned off when the illumination is off in the evening and the LED illumination unit 200 is turned off when the sunrise in the morning So that the LED lighting apparatus 1000 is operated.

Here, the first brightness value, the reference time, the low brightness value, or the reference brightness value may be set by a user input such as pressing a key input button provided on the user input unit 400, The device 1000 can be configured to reset these values even in the automatic power saving mode.

The automatic operation of the LED lighting apparatus 1000 according to the sensing or illumination of the sensing unit 300 may be performed by pressing a predetermined button provided on the user input unit 400, And can be selectively applied according to user input through an input method.

By selecting the automatic power saving mode, it is possible to cause the light to be turned on only when the person is present in the room or when the room or exterior illumination is dark, or the brightness of the room is automatically adjusted so as to maintain the predetermined reference illuminance, And it is possible to increase the convenience of the user because it is automatically operated without any additional operation.

Next, when the power switch unit 100 enters the second state, the apparatus control unit 500 may cause the LED lighting apparatus 1000 to be driven in the passive dimming mode. The manual dimming mode is a mode in which at least one of manually turning on / off and adjusting the light intensity is performed according to the user's input through the user input unit 400, in which the user sets the brightness to a specific brightness A case where it is desired to use the LED lighting apparatus 1000, a case where the power saving of the LED lighting apparatus 1000 is desired, and the like. As described above, in the passive dimming mode, the LED lighting unit 200 is turned on or off through an input method such as pressing a predetermined button provided on the user input unit 400 or touching the touch screen, As shown in FIG.

Specifically, the device control unit 500 controls the LED lighting unit 200 to emit light with a predetermined second luminance value when the power switch unit 100 is in the second state, The LED illumination unit 200 can be manually reset or the LED illumination unit 200 can be turned off according to the received user input and the LED illumination unit 200 extinguished by the user input can be lighted again You may. In this case, it is needless to say that the second luminous intensity value can be set through the user input unit 400.

According to the embodiment, when the LED illumination unit 200 is turned off by a user input to the user input unit 400, the brightness value at the time of the unlit state is stored in the memory unit 700 and the LED illumination unit 200 The device control unit 500 may be configured such that the LED lighting unit 200 is turned on with the brightness value stored in the memory unit 700. [ At this time, the brightness value at the time of the unlit state stored in the memory unit 700 is only applied to the case where it is lit again after being turned off by the user input unit, and does not affect the second brightness value. For example, when the power switch unit 100 is changed from the second state to the other state by the state change of the power switch unit 100 and then returns to the second state, the LED lighting unit 200 transmits the second The light is emitted or emitted at a luminance value.

The lighting of the LED lighting unit 200 by the user input unit 400 may be turned on or off and the manual brightness may be adjusted only when the power switch unit 100 is in the second state. It is possible to configure only the setting of the first luminance value, the lowest luminance value, the reference time, the reference luminance value, the second luminance value, and the like by the user input unit 400.

By selecting the manual power saving mode in this manner, the user has an advantage that the LED lighting apparatus 1000 can be used at a specific brightness according to his / her preference or need.

Finally, when the power switch unit 100 enters the third state or the fourth state, the apparatus control unit 500 may cause the LED illumination apparatus 1000 to be driven in the general illumination mode. The general illumination mode is a mode in which only the lighting and the light-off functions are performed at the maximum luminous intensity, and when the maximum brightness is desired due to a lot of human activity at night, the room is sufficiently bright to turn off the LED lighting apparatus 1000, And the like. In the general illumination mode, the user can turn on or off the LED lighting unit 200 in the same manner as the conventional general fluorescent lamp by turning on or off the switch.

Specifically, when the power switch unit 100 is in the third state, the LED lighting unit 200 is turned on or illuminated at the maximum luminous intensity (100%). When the power switch unit 100 is in the fourth state, The supply of external power to the lighting apparatus 1000 is interrupted, so that the LED lighting unit 200 can be configured to be forcibly extinguished.

As described above, the user can easily switch the power supply to the user's lighting (not shown) through the simple manner of turning on or off the power switch unit 100, that is, the first switch 110 and the second switch 120 By selecting an operation mode suitable for the use state, the utilization of the LED lighting apparatus 1000 can be enhanced, the convenience of the user can be increased, and unnecessary power consumption can be prevented.

When the power switch unit 100 includes only one power switch, the device controller 500 receives the mode setting input of the user through the user input unit 400, To set the operation mode, and to drive the LED lighting apparatus 1000 in one of the above-described automatic power saving mode, manual dimming mode, and general illumination mode. At this time, one of the three operation modes is set to a default mode by a predetermined setting method, and when the power switch unit 100 is turned on, the device is automatically driven in the default mode, The operation mode when the power switch unit 100 is turned off is stored in the memory unit 700. When the power switch unit 100 is turned on, And may be configured to be driven in a stored operation mode.

The power supply processing unit 600 may include a first switch 110 and a second switch 120 connected to the external power source 2000 in an ON state of at least one of the first switch 110 and the second switch 120, The AC power supplied from the outside can be rectified and supplied to the generated DC power LED illumination unit 200. [ The power processing unit 600 senses whether power is supplied from the outside through the first switch 110 or the second switch 120 so that the power of the first switch 110 and the second switch 120 Generate a signal for the ON or OFF state, and transmit the signal to the device control unit 500. [

Meanwhile, the power switch unit 100 may include only one power switch, as described above. In this case, the power switch unit 100 does not need to transmit a signal for ON or OFF state to the device control unit 500, and simply switches the power supply switch for interrupting or connecting the supply of the external power supply 2000 As well.

The specific configuration of the power supply processing unit 600 will be described in detail with reference to FIG. 2, and a detailed description thereof will be omitted here.

The smart LED lighting apparatus 1000 according to an embodiment of the present invention may further include a memory unit 700. [ The memory unit 700 may store a value set through the user input unit 400, that is, a first brightness value, a lowest brightness value, a reference brightness value, or a second brightness value to match the state of the power switch unit 100 . In addition, the memory unit 700 may store the brightness value at the time when the LED illumination unit 200 is turned off by the user input unit 400. FIG. Here, the memory unit 700 may be implemented as various types of nonvolatile storage devices known to those skilled in the art, such as EEPROM (Electrically Erasable and Programmable Read Only Memory), flash memory, and the like.

The first and second rectifying circuits 620 and 640 are circuits for converting the AC power inputted from the first and second filters 610 and 630 to DC and include a full wave rectifier circuit ). ≪ / RTI > The DC power output from the first and second rectifier circuits 620 and 640 is input to the SMPS module 650 and is connected to the SMPS module 650 through a diode and a resistor connected in parallel, As shown in FIG.

The SMPS module 650 is a component for reducing an input voltage of a high voltage to a voltage usable in the LED illumination unit 120. The SMPS module 650 converts a DC input voltage into a square wave type voltage using a semiconductor device as a switch, And a switching mode power supply (SMPS) that obtains a controlled DC output voltage through the switching power supply. The output filter 660 may remove the DC voltage inputted from the SMPS module 650 and provide the reduced voltage to the LED lighting unit 200.

2, when the external power supply 2000 is supplied through at least one of the first switch 110 and the second switch 120, the power supply processing unit 600 may supply an external power supply 2000 (M-SW SNSR, S-SW SNSR) for the ON or OFF state of the first switch 110 and the second switch 120 by detecting the supplied switch, (M-SW SNSR, S-SW SNSR) to the device control unit 500.
