Thus, the utilization and user convenience of the LED lighting device 1000 can be increased. A detailed configuration of the user input unit 400 and a user input method will be described with reference to FIG. 3, and a detailed description thereof will be omitted.

The device controller 500 is a component that controls various components of the smart LED lighting apparatus 1000 and processes various data, according to an embodiment of the present invention, to a central processing unit such as a microprocessor. Can be implemented.

The device controller 500 may control the LED lighting apparatus 1000 to be driven in an operation mode set corresponding to a combination of an ON or OFF state of a plurality of switches constituting the power switch unit 100. Can be. In particular, when the power switch unit 100 includes the first switch 110 and the second switch 120, the device controller 500 may include at least one of the first switch 110 and the second switch 120. Receives an ON or OFF state signal, determines the state of the power switch unit 100, and sets the automatic power saving mode, the manual dimming mode, and the setting corresponding to the determined state of the power switch unit 100; The LED lighting apparatus 1000 may be controlled to be driven in any one operation mode of the general lighting mode.

First, when the power switch unit 100 is in the first state, the device controller 500 may allow the LED lighting apparatus 1000 to be driven in the automatic power saving mode. In this case, the automatic power saving mode is a mode for automatically turning on, turning off, or controlling the brightness of the LED lighting unit 200 according to a sensing signal generated through sensing of illuminance or motion of the sensor unit 300. After a long period of absence, it is a mode suitable for the case where the user wants to automatically turn on the LED lighting apparatus 1000 or to save power when it becomes dark for the purpose of crime prevention or the like. In this case, the automatic power saving mode may be operated in different ways depending on the type of sensing signal transmitted to the device controller 500 through the detection of the sensor unit 300.

In detail, when the power switch unit 100 is in the first state, the device controller 500 causes the LED lighting unit 200 to light or emit light at a predetermined first luminance value, and the sensing unit 300 is configured to operate indoors. If it is determined that there is no motion for a predetermined reference time by analyzing a motion sensing signal transmitted by detecting a motion, the LED lighting unit 200 is turned off or the brightness of the LED lighting unit 200 is set to be lower than the first brightness value. Lower the brightness value, and again, if the movement of the room is detected, it may be configured to re-light the LED lighting unit 200 again to the first brightness value.

On the other hand, the device controller 500, in the first state of the power switch unit 100, when the sensing unit 300 detects the illuminance of the room and transmits an illuminance sensing signal, measured device illuminance and the predetermined reference illuminance value In comparison, the LED lighting unit 200 may be configured to perform at least one of lighting, lighting, and brightness control. According to an embodiment, the sensor for detecting the illuminance is installed outside the room where the LED lighting apparatus 1000 is installed, and when the measured external illuminance is lower than the reference illuminance value, the LED illuminating unit 200 determines the first intensity value. LED lighting unit 200 is turned on when the sun is lit in the evening, and the LED lighting unit 200 is turned off when the light is turned on or emitted, and the LED illuminating unit 200 is turned off when the light intensity is equal to or greater than the reference illuminance value. The LED lighting apparatus 1000 may be operated in a manner.

Here, the first luminance value, reference time, minimum luminance value or reference illuminance value may be set by a user input such as pressing a key input button provided in the user input unit 400, and the user may use LED lighting. The device 1000 may be configured to reset these values even when the device is operating in the automatic power saving mode.

On the other hand, the automatic operation of the LED lighting apparatus 1000 according to the movement or illumination detection of the above-described sensing unit 300, such as pressing a predetermined button provided on the user input unit 400, touch the touch screen, etc. Each may be selectively applied according to a user input through an input method.

By selecting the automatic power saving mode, it is turned on only when a person is indoors or when the interior or exterior illumination is dark, or the brightness is adjusted automatically so that the brightness of the interior maintains a predetermined standard illumination, thereby eliminating unnecessary waste of power. It can be prevented, and it can be operated automatically without additional manipulation, which can increase user's convenience.

Next, when the power switch unit 100 is in the second state, the device controller 500 may cause the LED lighting apparatus 1000 to be driven in the manual dimming mode. The manual dimming mode is a mode in which at least one of lighting, extinction, and brightness adjustment is manually performed according to a user's input through the user input unit 400. If you want to use the LED lighting device 1000, it is a mode suitable for when you want to reduce the power of the LED lighting device (1000). As described above, in the manual dimming mode, the LED lighting unit 200 is turned on or off or the predetermined unit is pressed through an input method such as pressing a predetermined button provided on the user input unit 400 or touching a touch screen. Furnace brightness may be adjusted.

In detail, when the device controller 500 and the power switch unit 100 are in the second state, the LED lighting unit 200 emits light at a preset second luminance value, and then a user input to the user input unit 400 is performed. When the reception is received, the brightness of the LED lighting unit 200 may be manually readjusted according to the received user input, or the LED lighting unit 200 may be turned off, and the LED lighting unit 200 turned off by the user input may be turned on again. You may. In this case, the second brightness value may be set through the user input unit 400.

According to an embodiment, when the LED lighting unit 200 is turned off by the user input to the user input unit 400, the brightness value at the time of turning off is stored in the memory unit 700, and the LED lighting unit 200 by the user input. When the light is turned on again, the device controller 500 may be configured such that the LED lighting unit 200 is turned on with the brightness value stored in the memory unit 700. In this case, the brightness value at the time of extinction stored in the memory unit 700 is only applied when the light value is turned on again after the extinction by the user input unit, and does not affect the second intensity value. For example, when the power switch unit 100 is changed from the second state to another state by the state change of the power switch unit 100, and then returns to the second state, the LED lighting unit 200 is the second state. It turns on or emits light at the intensity value.

Here, the lighting, turning off, and manual brightness control of the LED lighting unit 200 by the user input unit 400 is possible only when the power switch unit 100 is in the second state, and the power switch unit 100 is in a different state. In this case, only the first luminous intensity value, the lowest luminous intensity value, the reference time, the reference illuminance value, and the second luminous intensity value may be configured by the user input unit 400.

By selecting the manual power saving mode as described above, there is an advantage that the user can use the LED lighting apparatus 1000 at a specific brightness according to his or her preference or need.

Finally, when the power switch unit 100 is in the third state or the fourth state, the device controller 500 may cause the LED lighting apparatus 1000 to be driven in the general lighting mode. The general lighting mode is a mode in which only the function of turning on and turning off at the maximum brightness is performed. When there is a lot of human activity at night and wants the maximum brightness, the room is sufficiently bright to cut off the power of the LED lighting apparatus 1000, thereby consuming power. This mode is suitable when you want to reduce. In the general lighting mode, the user may turn on or turn off the LED lighting unit 200 by turning on or off the switch in the same manner as the conventional general fluorescent lamp.

Specifically, when the power switch unit 100 is in the third state, the LED lighting unit 200 is turned on or emitted at the maximum brightness (100%), and when the power switch unit 100 is in the fourth state, the LED As the supply of external power to the lighting device 1000 is cut off, the LED lighting unit 200 may be configured to be forcibly turned off.

As described above, the user lights the user through a simple method of turning on or off the power switch unit 100, that is, the first switch 110 and the second switch 120. By selecting the operation mode suitable for the use state, it is possible to increase the utilization of the LED lighting device 1000, increase the user's convenience and prevent unnecessary power waste.

On the other hand, when the power switch unit 100 is composed of only one power switch, when the device controller 500 receives the user's mode setting input to the user input unit 400, accordingly, the LED lighting apparatus 1000 The operating mode may be set, and the LED lighting apparatus 1000 may be driven in one of the automatic power saving mode, the manual dimming mode, and the general lighting mode. In this case, one of the three operation modes is set as the 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, or the device controller 500 When the power switch unit 100 is turned on, the operation mode when the power switch unit 100 is turned off is stored in the memory unit 700. It can be configured to be driven in a stored mode of operation.

The power processor 600 may include the first switch 110 and the 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. ) Can be supplied to the DC power LED lighting unit 200 generated by rectifying the AC power supplied from the outside. Meanwhile, the power processor 600 detects which of the first switch 110 and the second switch 120 to supply power from the outside, so that the power switch 600 of the first switch 110 and the second switch 120 A signal for an on or off state may be generated and the signal may be transmitted to the device controller 500.

On the other hand, the power switch unit 100, as described above can be composed of only one power switch. In this case, the power switch unit 100 does not need to transmit a signal for the ON (ON) or OFF (OFF) state to the device control unit 500, the power switch to simply cut off or connect the external power supply (2000) It will serve as a role.

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

The memory unit 700 may store a value set through the user input unit 400 to correspond to the state of the power switch unit 100, that is, a first luminance value, a minimum luminance value, a reference illuminance value, or a second luminance value. . In addition, when the LED light 200 is turned off by the user input unit 400, the memory 700 may store the brightness value at the time of turning off.
