Description

Since the circuit is designed to be optimized, when the user reduces the brightness of the lamp, the size of the driving power supplied to the lamp is reduced. The power factor is reduced compared to when the driving power is supplied at maximum, and electrical characteristics such as EMI This becomes incomplete.

Therefore, even if the user controls the input unit to reduce the brightness of the lamp to 50% in order to reduce the power consumption to 50% in the brightest state when the lamp is rated output, the power consumption is 50% due to the incompleteness of the above electrical characteristics. As the amount of power exceeding is consumed, there is a problem that the energy saving efficiency is low compared to the effect of reducing the brightness of the light, thereby not realizing energy saving.

In addition, since the lighting device is generally installed in a ceiling or a high wall position, the dimming input switch is installed in a low position wall so that the user can easily operate it with his bare hands. Therefore, when a lighting device is newly installed at the installation place, a dimming control line with a commercial power input line can be embedded on the wall to connect the lighting device and the dimming input switch to each other. Since the signal connection line for signal connection must be buried on the wall, the installation process is complicated and the installation cost is excessive.

Energy-saving lighting control device according to the present invention (hereinafter referred to as "light control device 100"), based on the input signal input through the input switch, such as the first switch 110 and the second switch 140, As a dimming control system to adjust the brightness of the light source unit 220, 420, 620 step by step, hereinafter the lighting control device 100 is installed in the lighting lamp 200, and the general light source 400 is installed in the lighting fixture 400 is fastened The case is divided into the case and installed in the power supply module 500 is fastened to the general lighting fixture 600 will be described by dividing the embodiment.

First, the configuration and function of the lighting control device 100 according to the first embodiment of the present invention installed in the lighting lamp 200 will be described with reference to FIGS. 1 to 4C.

1 to 4C, the lighting control apparatus 100 according to the first embodiment of the present invention includes a first switch 110 for outputting a first input signal which is a dimming control signal, and the first switch 110. A power supply circuit 120 for driving the light source 220 in accordance with the input signal is provided.

Here, the first switch 110 is disposed on one side of the outer surface of the lamp case 210 of the lighting lamp 200, as shown in FIG. 3, is manipulated by the user's touch operation, any dimming selected by the user A component that selectively generates a first input signal to be set as a step, and operates to select an arbitrary dimming step among a plurality of dimming steps, as shown in the figure, the first input corresponding to the selected dimming step Generates a signal and outputs the signal to the power supply circuit unit 120 connected to the signal.

In addition, the drawing illustrates that the plurality of dimming steps are divided into two dimming steps, such as 100% brightness and 50% brightness, but the present invention is not limited thereto, and may be divided into three or more dimming steps according to lighting purposes and user convenience. Of course.

The lamp case 210 is provided with a socket connector 230, a light source unit 220, and a first switch 110 fastened to a socket 33 to which commercial AC power is applied, and the power supply circuit unit 120 is disposed therein. ) Circuit components are mounted on the PCB and mounted in the circuit design state. Specific shape and size of the external shape of the lamp case 210 may be designed and manufactured in a variety of shapes and sizes, such as a general lamp.

The first input signal is a user input generated through the first switch 110 as a user manipulates and controls the first switch 110 installed in the lighting lamp 200 according to the first embodiment of the present invention. The second input signal, which will be described later as a signal, is distinguished based on the subject to generate.

In addition, the drawing illustrates that the first switch 110 is a switch of a sliding selection method, but is not limited thereto, and a plurality of selection terminals may be arbitrarily operated in the technical field to which the present invention belongs, such as a push button method and a rotation variable method. Any switch that can be selected can be applied.

In addition, as shown in FIG. 3, the first switch 110 may be provided with a display lamp 211 that emits light so that any dimming step selected by the user may be displayed to the outside. It is possible to clearly identify the set dimming step even at a certain distance apart position.

The power supply circuit unit 120 previously uses a commercial AC power applied to the light source unit 220 to emit light at a brightness corresponding to the dimming stage selected according to the first input signal transmitted from the first switch 110 for each dimming stage. As shown in FIG. 2, the rectifier 121, the power supply unit 122, the switching unit 123, and the control unit 125 are converted into a driving power source having a predetermined size and supplied to the light source unit 220. It may be provided to include.

However, in the case of a light source driven by a DC power source such as an LED light source according to the type of the light source unit 220, a circuit configuration such as a converter for converting AC power to DC power may be included. Hereinafter, the light source unit 220 will be described with an example that the LED terminal is a bundle of LED panels.

First, the rectifier 121 is a component for rectifying a commercial AC power applied by being connected to the socket connector 230 of the lighting lamp 200 with a power supply line to a DC power source, using a plurality of electronic components. By configuring the rectifier circuit, its function can be realized.

The power supply 122 is a component that receives the DC power rectified by the rectifying unit 121 and converts the DC power into a form of driving power capable of driving the light source unit 220. As shown in FIG. Each of the DC power rectified by 121 may be provided to include a plurality of divided power supply unit 122a for converting into a form of a separate driving power of a predetermined size and individually supplying to the light source unit 220.

Here, the sum of the individual driving powers converted by the plurality of divided power supply units 122a is a size capable of emitting the light source 220 most brightly, that is, a size of driving power capable of rated output, and the switching unit. The brightness of the light source unit 220 is dimmed step by step according to the number of divided power supply units 122a receiving the rectified DC power according to the switching operation of 123.

For example, the power consumption of the light source unit 220 of the lighting lamp 200 is 100W (watts) and the brightness when the light source unit 220 is rated output is 10,000 lm (lumen), the power supply unit 122 ) Is provided with two divided power supply units 122a for converting and outputting the individual driving power corresponding to 50 W of power consumption, corresponding to 50 W power consumption from the two divided power supply units 122a. When the individual driving power is output and supplied to the light source unit 220 simultaneously, the light source unit 220 emits light at 10,000 lm, and the individual drive power corresponding to the power consumption of 50 W is supplied from only one divided power supply unit 122a. When the output is supplied to the light source unit 220, the light source unit 220 will emit light at 5,000lm.

In addition, in the drawing, two divided power supply units 122a are provided in the power supply unit 122 and are divided into two stages. However, the present invention is not limited thereto and may be provided in a number of three or more according to the designed dimming step. Of course. The predetermined sizes of the individual driving powers output from the divided power supply units 122a may be set to the same or different sizes.

For example, the power consumption of the light source unit 220 is 100W (watts), the brightness when the light source unit 220 is rated output is 10,000 lm (lumen), and the power unit 120 has three divided power supply units 122a. ), One divided power supply unit 122a converts to the size of the individual drive power corresponding to 20W power consumption, and the other divided power supply unit 122a converts the individual drive power corresponding to 30W power consumption. The split power supply unit 122a may convert the power to the size of the individual driving power corresponding to the power consumption of 50W.

In this way, the power supply unit 120 is provided under conditions that satisfy the condition that the sum of the individual drive powers converted from each of the divided power supply units 122a is the size of the drive power capable of rated output of the light source unit 220. The size of the individual driving power that the divided power supply unit 122a has may be variously set.

In addition, each of the divided power supply units 122a includes transformers, zener diodes, and switches, including resistors, capacitors, and transistors, which are general electronic devices, so as to convert the input DC power into a form of power capable of driving the light source unit 220. It may be composed of electronic components such as various electronic devices such as elements, wherein each of the electronic components configured in each of the divided power supply unit 122a is based on the size of the individual driving power set in advance in the corresponding divided power supply unit 122a. The circuit is designed to optimize efficiency at rated output. Therefore, each divided power supply 122a can maintain a high power factor even if it is converted to the size of the corresponding individual driving power, and the factors that can incompletely electrical characteristics such as EMI generation can be minimized.

Here, converting a variety of electronic devices such as a switching mode power supply (SMPS) into a form of a predetermined output power for driving the light source 220 to emit light is widely used in the art. Since it is a well-known technique, detailed description will be omitted.

The switching unit 123 receives a control signal output from the control unit 125 and switches the DC power selectively rectified to each divided power supply unit 122a of the power supply unit 120 according to the control unit 125. As a component, the power supply line connected to each of the divided power supply 122a and the rectifier 121 so that the DC power rectified by the rectifier 121 is independently applied to each divided power supply 122a. Disposed on the line, and selectively short-circuits each power supply line branched by each of the divided power supply units 122a according to the control signal so that DC power is cut off from the divided power supply unit 122a or by contacting the power supply line. The DC power of the rectifier 121 is supplied to each divided power supply unit 122a. That is, the switching unit 123 operates to supply the rectified DC power selectively to all the divided power supply units 122a or some of the divided power supply units 122a configured in the power supply unit 120.

The control unit 125 is a control IC or the like, and the light source unit 220 according to an input signal is a component for driving light emission at a predetermined brightness and power consumption for each dimming step, the signal connection with the first switch 110 The control unit outputs a control signal to the switching unit 123 such that the light source unit 220 emits light in the dimming step selected according to the first input signal.

Here, when the divided power supply unit 122a does not transmit the rectified DC power according to the user input signal when the size of each individual driving power converted by each divided power supply unit 122a is the same. The controller 125 may control the switching unit 123 so that the DC power is not transmitted to each divided power supply unit 122a while returning in a predetermined order.

For example, when two divided power supply units 122a are configured in the power supply unit 120 as shown in FIG. 2, when the user wants to use 50% of the brightness by the user's selection, the user's first input signal is detected by the detection unit 160. The DC power is transmitted to one of the divided power supply units 122a of the two divided power supply units 122a and the DC power is not transmitted to the other divided power supply unit 122a. 123 is switched, where the divided power supply unit 122a to which the DC power is not transmitted is fixed every time the dimming control is performed at 50% brightness if the divided power supply unit 122a is fixed. The lifespan is shortened while the conversion drive is continuously performed, and the divided power supply unit 122a in which the DC power is not transmitted does not perform the conversion drive, resulting in a relatively long lifespan.

Accordingly, as described above, the driveable time of each of the divided power supply units 122a (the life of the divided power supply unit 122a) by switching control in a predetermined order so that DC power is not evenly transmitted to each of the divided power supply units 122a. The difference between the two can be minimized to increase the overall life of the light source unit 220.

In other words, while driving the divided power supply unit 122a evenly in order, the remaining life is equally consumed.

On the other hand, when the user wants to operate the dimming step for the lighting lamp 200 according to the preferred embodiment of the present invention, the first switch 110 as shown in Figure 3 the lamp case 210 of the lighting lamp 200 Is disposed so as to be exposed to the outer surface of the lighting lamp 200 can be easily manipulated to the desired dimming step by direct manipulation in the state installed in the socket 33 or the lighting fixture 300, but is shown in Figure 4b As described above, the lighting lamp 300 is assembled in such a manner as to surround the side of the lighting lamp 200 as well as the bottom thereof, that is, the lighting lamp 200 and the first switch 110 of the lighting lamp 300. When the cover is covered by the luminaire case 310 and trapped from the outside, the user must dismantle the assembled structure whenever the dimming control is desired, and operate the first switch 110 in a desired dimming step and reassemble and use it. Cause this There was a problem with.

In the lighting control apparatus 100 according to the first preferred embodiment of the present invention, in order to solve this problem, the external surface of the luminaire case 310 of the luminaire 300 in signal connection with the power supply circuit unit 120. By disposing the second switch 140 in the dimming control can be easily performed without disassembling the assembled structure of the lighting fixture 300.

In addition, when the lighting lamp 200 or the lighting fixture 300 to which the lighting lamp 200 is fastened is installed at a low position where the user's hand can easily reach, the user extends the hand and directly switches the first switch 110. Although it can be easily manipulated to the desired dimming step, the lighting lamp 200 or the lighting fixture 300 to which the lighting lamp 200 is fastened is not touched by the user from the ceiling 31 or the wall 32 If it is installed in a high position does not occur, the user needs to operate the first switch 110 in a state in which an auxiliary tool such as a ladder, chair, etc. whenever the user wants to control the lighting lamp 200 to the desired brightness occurs. Can be.

Therefore, in order to solve such inconvenience in the lighting control device 100 according to the preferred embodiment of the present invention, the user of the above-described second switch 140 on the wall 32, like the power switch 20 installed in advance. It may be installed at a suitable height that is easily accessible by the operator. As a result, it is possible to easily dimming the lighting lamp 200 or the lighting lamp 300 equipped with the lighting lamp 200 disposed at a high position out of reach of the user.

Like the first switch 110 described above, the second switch 140 operates to select an arbitrary dimming step among a plurality of dimming steps, as shown in FIGS. 4B and 4C. An input switch for outputting a second input signal corresponding to the dimming step selected as 2 to the power supply circuit unit 120, the covered state of the lighting lamp 200 or the lighting lamp 200 and the lighting lamp 200 Is placed on the outer surface of the luminaire case 310 of the luminaire 300 or the lower position that can be easily controlled on the wall 32, depending on the height of the luminaire 300 is fastened.

In this case, when the first switch 110 and the second switch 140 are operated in different dimming steps, an error occurs when the first input signal and the second input signal are simultaneously input to the power supply circuit unit 120. This may cause a problem in that the light source unit 220 cannot be driven in a desired dimming step.

Accordingly, as illustrated in FIG. 3, the dimming step divided into a plurality of first switches 110 includes an external input mode step of blocking output of the first input signal by the first switch 110. The power supply circuit unit 120 is a dimming step selected according to the second input signal when the second input signal is transmitted from the second switch 140 in a state in which the first switch 110 is selected as an external input mode step. The light source unit 220 operates to convert the commercial AC power applied to emit light into driving power having a predetermined size and supply the same to the light source unit 220.

That is, the second switch 140, like the first switch 110, is operated so as to be set in any dimming step by the user's touch operation, the position installed with the first switch 110 Can be distinguished. That is, the first switch 110 is disposed on the lamp case 210 of the lighting lamp 200, while the second switch 140 is a luminaire case 310 or a height that can be easily manipulated by a user. There is a difference in that it is disposed at an arbitrary position such as the wall surface 32.

In addition, the second switch 140 is installed at a suitable height that can be easily reached by the user's hand as shown in Figure 4a and 4b of the lighting lamp 200 or the lighting fixture 300 equipped with the lighting lamp 200 In order to control the on and off, it can be arranged in a position close to the power switch 20 installed on the wall 32 in advance, in the figure the power switch 20 and the second switch 140 in the form of each individual switch Although illustrated, the present invention is not limited thereto, and the switches 20 and 140 may be disposed on one switch module to be disposed on the wall 32 in a more concise and beautiful form.

On the other hand, in the signal transmission method for transmitting the second input signal output through the second switch 140 to the control unit 125 of the power supply circuit unit 120, the second switch 140 like the wireless remote controller controller method The second input signal output from the wireless communication network may be transmitted to the control unit 125, and the commercial AC power applied to the power supply circuit unit 120 from the commercial AC power input terminal 10 as indicated by a dotted line in FIG. It is also possible to use a method (power line communication method) of flowing a second input signal on the input.

In this case, the form of the signal may vary according to the method, and the method of changing the size of the physical quantity of the commercial AC power supply instantaneously and inputting a predetermined analog signal on the commercial AC power supply such as power line communication. Can be distinguished in a manner.

The physical quantity may be a phase, a current, or a voltage of a commercial AC power, and the commercial AC power is a driving power for driving the light source unit 220 to emit light. It is preferable to change the physical quantity in a short time within a range that the 160 can detect.

In this case, the second switch 140 should be provided with a separate circuit configuration for instantaneously changing the physical quantity of the commercial AC power for each dimming step divided into a plurality to be transmitted to the detection unit 160. In the case of the method of inputting the analog signal. For each dimming step divided into a plurality of separate circuits are required to input different analog signals to the commercial AC power supply.

The detection unit 160 is disposed on a power supply line between the second switch 140 and the rectifier 121 to detect a second input signal input on the commercial AC power by the second switch 140. As a component for outputting a corresponding detection signal to the controller 125, a circuit configuration for detecting the second input signal varies according to a method in which the second input signal is input on a commercial AC power supply.

In more detail, when the phase of the commercial AC power is instantaneously changed by the second switch 140 according to the method of inputting the second input signal, the detection unit 160 performs the phase of the commercial AC power. When the detection sensor, the current of the commercial AC power supply is instantaneously changed, the detection unit 160 may be a current detection sensor of the commercial AC power supply, the magnitude of the voltage of the commercial AC power supply is instantaneously changed In this case, the detection unit 160 may be a voltage detection sensor of a commercial AC power supply.

In addition, when different analog signals are input to the commercial AC power supply, the detection unit 160 may be an analog signal detection sensor that detects the analog signal as in general power line communication.

In addition, the detection unit 160 transmits a detection signal classified according to an arbitrary dimming step selected by a user's operation according to the input second input signal through a signal line separately connected to the control unit 125.

In addition, in FIG. 4C, for example, the second switch 140 is a rotary variable type switch configured to rotate the selection button at a predetermined angle, but is not limited thereto, and is not limited thereto. Any switch capable of arbitrarily selecting a plurality of selection terminals in the technical field to which the present invention belongs, such as a switch, may be applied. The second switch 140 displays an external dimming step selected by a user. It is preferable that a display lamp 141 is provided to emit light.

In addition, the dimming step divided into a plurality of the second switch 140 may include a pre-input mode step of blocking the output of the second input signal by the second switch 140. The pre-input mode step refers to a mode step set to simply turn on and off only by the pre-installed power switch 20 to control the power of the lighting device on and off without a separate dimming control.

On the other hand, the operation principle of the dimming control of the light source unit 220 by the lighting control device 100 according to a preferred embodiment of the present invention as described above will be described by way of example.

First, one input signal of the first input signal or the second input signal for dimming control from the first switch 110 or the second switch 140 in a dimming step 1 (power consumption 100W, 10,000 lm) is a power source. When output to the control unit 125 of the supply circuit unit 120, the control unit 125 transmits a control signal to the power supply unit 120 in the operation state corresponding to the dimming step 1, the switching unit 123 )

The switching unit 123 short-circuits the power supply lines respectively connected to the two divided power supply units 122a to apply the DC power rectified by the rectifying unit 121 to the two divided power supply units 122a at the same time. Each of the divided power supply units 122a converts the applied DC power into the size of the individual driving power corresponding to the power consumption of 50W and simultaneously applies the divided power supply unit 220 to the light source unit 220 so that the light source unit 220 has a brightness of 10,000 lm. Light emission is driven at 100W.

Subsequently, one input signal of the first input signal or the second input signal for dimming control from the first switch 110 or the second switch 140 in the second dimming step (power consumption 50W, 5,000 lm) is controlled. When output to 125, the controller 125 outputs a control signal to the switching unit 123 that the power supply unit 120 can convert and drive to an operation state corresponding to the dimming step 2.

The switching unit 123 opens a power supply line connected to one divided power supply unit 122a according to a preset order among power supply lines connected to the two divided power supply units 122a, and the other divided power supply unit ( The other power supply line 122a connected to the power supply line 122a is short-circuited so that the other divided power supply unit 122a converts the applied DC power to the size of the individual driving power corresponding to the power consumption of 50W to the light source 220. By applying the light source 220 is driven to the light emitting 50W having a brightness of 5,000lm.

Subsequently, an input signal of one of the first input signal and the second input signal for dimming control from the first switch 110 or the second switch 140 in three dimming steps (power consumption 0W, 0lm) is controlled by the control unit. 125, the control unit 125 outputs, to the switching unit 123, a control signal that can be converted and driven by the power supply unit 120 in an operation state corresponding to the dimming operation 3. The light source unit 220 is turned off by 123 opening the power supply line connected to the other divided power supply unit 122a to stop the conversion driving of all the divided power supply units 122a.

Subsequently, one input signal of the first input signal or the second input signal for dimming the second dimming step (power consumption 50W, 5,000 lm) from the first switch 110 or the second switch 140 is controlled. When output to 125, the controller 125 outputs a control signal to the switching unit 123 that the power supply unit 120 can convert and drive to an operation state corresponding to the dimming step 2. At this time, the control unit 125 changes the order to short-circuit the power supply line connected to the other divided power supply unit 122a which has not been converted and driven before, and the power supply line connected to the one divided power supply unit 122a is opened. The divided power supply unit 122a converts the applied DC power into the magnitude of the individual driving power corresponding to the power consumption of 50W, and applies the divided power supply unit 122a to the light source unit 220. It drives light at 50W with a brightness of 1000lm.
