1 and 2, the LED lighting apparatus 100 of the present embodiment includes a power supply unit 10, a switch unit 20, a control unit 30, a light source unit 40, a storage unit 50, .

The power supply unit 10 serves to supply power required for driving the LED lighting apparatus 100.

The input AC power supplied from the power supply unit 10 is rectified to a DC power source through a rectifier after noise and electromagnetic waves are removed and smoothed from the filter of the LED lighting apparatus 100 and the LED lamps 40-1, 40-2, ..., 40-N can transmit the power necessary for light emission. At this time, the rectified DC power may be used as the electric power of the light source unit 40 by being charged in the charging element of the LED lighting apparatus 100 or the like.

The switch unit 20 includes a switching element that serves to supply or cut off power to a power source supplied from the power source unit 10 to the LED illumination apparatus 100. [

The switch unit 20 includes a switch 21 positioned on the wall of the room or the like for turning on or off according to the user's hand movements and a selection button for applying one or more turn-on or turn-off signals according to a predetermined pattern 22).

The light source unit 40 includes a plurality of LED lamps 40-1, 40-2, ..., and 40-N that emit light in accordance with power supply. At this time, the LED lamps 40-1, 40-2, ..., and 40-N are independently configured to be separately controllable.

The LED lamps 40-1, 40-2, ..., and 40-N included in the light source unit 40 may function as a light source to emit yellow light, green light, , And white light. At this time, the energy levels of the LED lamps 40-1, 40-2, ..., and 40-N are different depending on the components of the compound semiconductor composing the LED lamps 40-1, 40-2, ..., 40- , ..., 40-N are determined.

The storage unit 50 is a storage unit storing a program used by the LED lighting apparatus 100 to perform the dimming operation.

The storage unit 50 may store a program defining a power supply time point and a supply power amount for each of the plurality of LED lamps 40-1, 40-2, ..., 40-N included in the light source unit 40 .

The communication unit 60 is a configuration for receiving and storing a program in the storage unit 50 via wired / wireless communication from the outside, or receiving a signal for setting a specific program. The communication unit 60 may include an interface for transmitting and receiving data through a communication network or a short-range wireless communication.

The present embodiment is configured to include the communication unit 60. However, according to the embodiment, the program may be stored in the storage unit 50 at the time of manufacturing the LED lighting apparatus 100 without the communication unit 60. [

The control unit 30 controls the overall operation of the LED illumination device 100 that dims the light using the LED lamps 40-1, 40-2, ..., and 40-N, .

The control unit 30 controls dimming of the LED lamps 40-1, 40-2, ..., and 40-N included in the light source unit 40 using the power supplied from the power source unit 10. At this time, And performs the corresponding dimming control by referring to the program of the storage unit 50 in accordance with the switching pattern of the switch unit 20. [

First, the switch unit 20 performs a switching operation of supplying power or shutting off power according to the turn-on or turn-off of the input signal through the switch 21. [ At this time, the switching operation of the switch unit 20 according to a user's manual operation or the like can constitute a certain pattern.

For example, the switching operation of continuously converting the switch unit 20 into the turn-on, turn-off, and turn-on states can form one pattern. Also, after the switch unit 20 is turned on for a relatively short period of time and the switch unit 20 is turned off for a relatively long period of time, the switch unit 20 is again turned on And the like.

When the switch unit 20 is turned on or off according to a specific pattern, the control unit 30 detects the switch unit 20 and displays the LED lamps 40-1, 40-2, ..., 40-N.

At this time, the controller 30 can use the counter 32 to sense the number of times the switch unit 20 alternately supplies power or cut off the power, and the timer unit 31 can control the switch unit 20, The switch unit 20 can detect the length of the power supply period or the power cutoff period at the time of switching and also detects the switching operation sequence in which the switch unit 20 supplies power or cuts off the power using the counter 32 or the timer 31 .

At this time, the switching pattern input to the switch unit 20 may be inputted through the switch 21 according to the hand operation of the user, but may also be inputted through the select button 22 provided to the switch unit 20 . That is, the switch unit 20 may include a selection button 22 for selecting each switching pattern, and each selection button 22 may be matched with a pre-programmed switching pattern. In this case, the corresponding switching operation can be automatically performed according to the user's selection of the selection button 22. At this time, the switch unit 20 is configured to store the switching pattern corresponding to each selection button 22, , An arithmetic unit for executing the corresponding switching pattern, and the like.

In this embodiment, the control unit 30 performs a corresponding dimming control operation according to the switching pattern of the switch unit 20. At this time, the dimming control by the control unit 30 can be performed in various forms.

The controller 30 controls the LED lamps 40-1 and 40-2 of the light source unit 40 by using a power source input through the power source unit 10 or a charging element inside the LED lighting apparatus 100 charged using the power source. -2, ..., 40-N to emit light.

At this time, the control unit 30 can control dimming of the light source unit 40 by adjusting the amount of power supplied to the plurality of LED lamps 40-1, 40-2, ..., and 40-N. The divergence illuminance of the light source unit 40 increases when the control unit 30 supplies a relatively large amount of power and conversely the divergence illuminance of the light source unit 40 decreases when a relatively small amount of power is supplied.

In this case, the control unit 30 can adjust the total illuminance by adjusting the total amount of electric power supplied to the plurality of LED lamps 40-1, 40-2, ..., and 40-N, -1, 40-2, ..., 40-N, the total amount of power supplied to some LED lamps may be adjusted to be different from the amount of power supplied to other LED lamps.

For example, the control unit 30 can separately adjust the amount of power according to the dim color of each LED lamp among the plurality of LED lamps 40-1, 40-2, ..., and 40-N. In this case, the LED lighting apparatus 100 can perform the dimming operation with various colors or roughness according to the user's selection.

At this time, the control unit 30 may match a specific lighting condition with a specific switching pattern and store the specific lighting condition in the storage unit 50 according to a user's input signal inputted through the communication unit 60 using a computer, a remote controller or other input device The user can then input the switching pattern through the switch unit 20, thereby allowing the control unit 30 to perform the dimming control according to the dimming condition set by the user.

In addition, in the embodiment of the present invention, the controller 30 supplies power to some LED lamps among the plurality of LED lamps 40-1, 40-2, ..., and 40-N, The dimming of the light source unit 40 can be controlled.

The control unit 30 can control the dimming of the light source unit 40 by adjusting the amount of power supplied to the entire LED lamps 40-1, 40-2, ..., 40-N that are turned on, -1, 40-2, ..., 40-N are not controlled in proportion to the amount of power supplied, but are changed in a non-linear manner.

On the other hand, when power is supplied to some LED lamps among the plurality of LED lamps 40-1, 40-2, ..., 40-N, the number of LED lamps to which power is supplied, 40-1, 40-2, ..., 40-N, the total illuminance of the light source unit 40 can be adjusted according to the ratio of the LED lamps that are turned on.

When the dimming control corresponding to the switching pattern input through the switch unit 20 is performed, the control unit 30 determines the number of LED lamps to be dimmed for each switching pattern, and adjusts the illuminance of the light source unit 40 accordingly The divergence can be controlled linearly.

However, when only a specific LED lamp among the plurality of LED lamps 40-1, 40-2, ..., 40-N is preferentially turned on, the lifetime of the specific LED lamp may be shorter than that of other lamps, As a result, some of the LED lamps may be inoperable, resulting in costly waste of replacing the entire LED lamps 40-1, 40-2, ..., 40-N.

In this case, the control unit 30 alternately turns on some LED lamps which are supplied with power from among the plurality of LED lamps 40-1, 40-2, ..., and 40-N, So that the lamps 40-1, 40-2, ..., 40-N can be uniformly turned on. As a result, the lifetime of the plurality of LED lamps 40-1, 40-2, ..., and 40-N can be relatively uniformly controlled, and the entire life of the light source unit 40 can be extended.

At this time, the control unit 30 can control the power supply time point for each of the plurality of LED lamps 40-1, 40-2, ..., 40-N by using the timer 31, Can be used to control the turn-on or turn-off sequence of the plurality of LED lamps 40-1, 40-2, ..., 40-N.

An example of information that the LED lighting apparatus 100 refers to in performing dimming control will be described with reference to FIG.

3 is a table showing the dimming control level corresponding to the switching pattern according to the embodiment of the present invention.

The table of FIG. 3 may be information stored internally by the LED illuminating apparatus 100 for reference in dimming control, and is not limited to the form of the information although it is shown in the form of a table.

Referring to FIG. 3, a 'dimming control level' item corresponding to the 'switching pattern' item can be confirmed at the top.

'On' indicates a state in which the switch is turned on to supply power, and 'off' indicates a state in which the switch is turned off and the power is off.

The switching pattern 'on / off / on' represents a pattern in which the switch is continuously switched between turn-on, turn-off and turn-on states. And the corresponding dim control level is '1'.

If a switching pattern in which the switch is turned on, turned off, or turned on is inputted, the LED illuminating device confirms that the corresponding dimming control level is '1' in the table of FIG. 3 and performs the corresponding dimming control .

Similarly, the switching pattern 'on / off / on / off / on' represents a pattern in which the switch is continuously switched between turn-on, turn-off, turn-on, turn-off and turn-on states. And the corresponding dim control level is '2'.

Accordingly, when a switching pattern in which the switch is turned on, turned off, turned on, turned off, or turned on is input, the LED lighting apparatus confirms that the corresponding dim control level is '2' And performs the corresponding dimming control.

In FIG. 3, the dimming control level '1' or '2' may mean divergence illumination itself or the like, and may mean a promised symbol or the like referring to another specific dimming condition.

The switching pattern may be formed in consideration of the period during which the switch is turned on or the period during which the switch is turned off. For example, a turn-on or turn-off for a relatively short period of time and a turn-on or turn-off for a relatively long period of time may be promised to mean a different pattern.
