1 is a view showing the configuration of a system for adjusting the illuminance of a plurality of lights according to an embodiment of the present disclosure. The system 100 for adjusting the illuminance of the plurality of lights may receive an input for controlling the illuminance from the external input device 170. An example of the external input device 170 includes a lighting management system in which a plurality of computers are combined, and may be a central control monitoring device that is controlled and managed centrally. Such a central control monitoring device can be implemented with a lighting control system of a large building. On the other hand, the touch screen combined with one computer can monitor the lighting conditions in real time and set the degree of illumination control through the touch screen.

In addition, in another embodiment of the external input device 170 in the present specification, such as a keypad or a remote switch, there is a function that allows the user to finely adjust the illuminance of the illumination with a predetermined illuminance for a plurality of lights. Can be combined.

The external input device 170 may also set information on lighting illumination control and information on / off time, and the set information may be set by the external control unit through the external input receiver 150 in the external input device 170. Unit, MCU, 110).

The external input receiver 150 transmits the information received from the external input device 170 to the central controller 110.

The central controller 110 adjusts illuminance of the plurality of lights according to illuminance adjustment information set from the outside. The central controller 110 controls the current controller 130 and the voltage controller 140, which are embodiments of the illuminance controller for adjusting the illuminance, and control the dimming selector 120. The illuminance control unit generates an illuminance control signal, and receives a control signal for adjusting the illuminance at the central control unit 110 and generates a signal in which current, voltage, etc. are adjusted to adjust the illuminance according to illumination.

Among the lights 160a, 160b, 160c,..., And 160n, the illumination whose illumination is controlled through a current is controlled by the current controller 130. Examples of the lighting to control the illuminance in the current controller 130 may be a light emitting diode (LED) light, an organic light emitting diode (OLED) light, or the like.

The illumination control of the illumination through the voltage among the lights 160a, 160b, 160c,..., And 160n is controlled by the voltage controller 140. Examples of the illumination to control the illuminance in the voltage control unit 140 may be a fluorescent lamp, incandescent lamp, halogen lamp and the like.

Since the current controller 130 and the voltage controller 140 are used to adjust the illuminance of the plurality of lights, the current controller 130 and the voltage controller 140 may include a plurality of semiconductor devices to control the current and the voltage of the plurality of lights, or may include two or more current controllers. It may consist of two or more voltage controllers. According to one embodiment of the present specification, a plurality of semiconductor devices may be included in one current controller 130 to hold a plurality of inputs / outputs to control a plurality of currents. In addition, according to another embodiment of the present specification, one current controller 130 may adjust the illuminance of one lighting, and a plurality of such current controllers may be mounted to control the current of the lighting. The voltage controller 140 may also be provided in the same manner. Of course, one current controller 130 or voltage controller 140 may control a plurality of lights. In this case, the plurality of controlled lights will control the illuminance at the same rate.

The current / voltage controlled by the current controller 130 and the voltage controller 140 to adjust the illuminance is input to the dimming selector 120. Meanwhile, the central controller 110 controls the dimming selector 120 so that a predetermined controlled current / voltage is applied to the multi dimming output port 180, and the applied current / voltage is each of a plurality of lights ( 160a, 160b, 160c, ..., 160n) to adjust the illuminance. In FIG. 1, the dimming selector and the multi dimming output port exist separately, but the dimming output port may be included in the dimming selector.

An embodiment of the central control unit 110 of FIG. 1 may be a 32-bit processor. In 32-bit processors, which lighting control is controlled can be achieved through 32-bit command assignment. For example, by assigning a series of k bits (k bits) for the lights to be controlled, and assigning m bits (m bits) to the illuminance level of the corresponding lights, control to adjust the illuminance level of a specific light You can generate a signal.

2 is a diagram illustrating a detailed configuration of a current controller and a voltage controller according to an embodiment of the present specification. For convenience of description, in the exemplary embodiment of FIG. 2, there are four lights such as 260a, 260b, 260c, and 260d, among which 260a and 260b are lights whose illumination is controlled by a current controller, and 260c and 260d are voltage controls. Illumination is controlled by

Since the entire configuration is the same as that of FIG. 1, the description of FIG. 1 will be replaced. The plurality of current controllers 232 and 234 and the voltage controllers 242 and 244 are configured to control respective lights. The dimming selector 120 and the multiport output unit 180 are displayed to expose internal circuit connections.

In the system 200 of FIG. 2, the current controllers 232 and 234 adjust the illuminance of 260a and 260b, respectively. 260a and 260b are lights in which illumination is controlled through current control, and one embodiment may be LED lighting or OLED lighting.

The central control unit 110 receiving information on the illumination control from the outside controls the current controllers 232 and 234 or the voltage controllers 242 and 244 to adjust the illumination of the illumination requiring illumination control.

Looking at the example of controlling the illuminance of the lighting by the current control, when the illuminance adjustment for the 260a illumination from the outside is requested, the central controller 110 may adjust the current controller 232. As an example of the current controllers 232 and 234, analog dimming and pulse width modulation dimming control functions are possible. In the case of the analog dimming function, the intensity of the current applied to the illumination can be adjusted by adjusting the current cycle. PWM dimming, on the other hand, repeats a number of operations that turn the current on and off for a short time. The frequency of the start-resume cycle, on and off, must be faster than the visually detectable cycle to avoid the flicker effect. If the light is an LED, a frequency above 200 Hz is appropriate. In the embodiment of FIG. 2, the current controllers 232 and 234 may be implemented using a PWM dimming module or a chip.

Meanwhile, in the system 200 of FIG. 2, the voltage controllers 242 and 244 adjust the illuminance of 260c and 260d, respectively. 260c and 260d are illuminations whose illumination is controlled through current control, and an embodiment may be a fluorescent lamp, a halogen lamp, an incandescent lamp, or the like.

Looking at the example of controlling the illuminance of the lighting by the voltage control, when the illuminance control for the 260c illumination from the outside is requested, the central controller 110 may adjust the voltage controller 242. An embodiment of the voltage controllers 242 and 244 may be an insulated gate bipolar transistor (hereinafter, referred to as 'IGBT').

IGBT provides a switching function that blocks or prevents the flow of electricity, and has low driving power, frequency characteristics that can be applied to on-voltage and intermediate frequencies (around 100kHz).

Of course, in addition to the IGBT, the thyristor, triac, and the like may be provided as components for voltage control. Cylist is a device suitable for high breakdown voltage and large capacity without tum-off function, and is commonly used in power system with low operating frequency, especially in large power converters that need capacity of 10MW ~ 100MW. Since multiple devices are used in series / parallel connection, it is necessary to increase the breakdown voltage and current capacity of each device. In addition, in order to solve the problem of insulation and noise of the gate circuit in the high voltage circuit, there is a need for an optical signal trigger or a high withstand voltage and a large capacity optical thyristor.

Although the current controllers 232 and 234 and the voltage controllers 242 and 244 are illustrated as being connected to the output port in the dimming selector 120 of FIG. 2, this shows the switched and connected results for convenience of description. The dimming selector 120 may change which port the signal provided from the illumination control unit, such as the constant current or the constant voltage, is connected to, and may be set at the time of installing the lighting or the time of replacing the lighting.

In addition, although the current controllers 232 and 234 and the voltage controllers 242 and 244 of FIG. 2 are respectively shown to control one lighting, one current controller or one voltage controller may control a plurality of lights. have. For example, the illumination of LEDs 1 and 2 can be controlled in the same manner through one current controller. In addition, the fluorescent and incandescent lamps may be controlled in the same manner through a single voltage controller. In this process, when the available voltages of fluorescent lamps and incandescent lamps are different, the voltage is provided according to the available voltage using a DC / DC converter, and the dimming of the lighting by the voltage can be implemented in one voltage controller.

3 is a diagram illustrating a configuration of a current controller according to an embodiment of the present specification. The above-described current controllers 130, 232, and 234 are capable of analog dimming and pulse width modulation dimming control functions. The current controller 300 of FIG. 3 uses pulse width modulation (PWM). The dimming structure is shown. In the case of PWM dimming, an oscillator (331) is used to repeat a number of operations that turn the light's current on and off for a short time. The signal 310 input to the oscillator 331 refers to a control signal for adjusting the illumination of the illumination in the central controller 110 described with reference to FIGS. 1 and 2. The signal provided by the central controller 110 to adjust the illuminance is input to the oscillator 331, and the oscillator 331 generates a predetermined waveform such as 336. The signal of the generated waveform is input to the gate controller 332, and the signal 339 outputted to the dimming selector through the DC 24V and the input waveform signal is switched in the dimming selector to repeatedly turn on and off the connected illumination for a predetermined time. . As mentioned earlier, if the LED is turned on and off for a short time at an interval that is hard to see, the illumination control signal is the interval between turning on and off. The dimming control signal can be dimmed by repeatedly turning the light on and off.

The circuit protection unit 335 may prevent excessive current from flowing by using a soft starter, a low drop-out (LDO) regulator, or the like.

In FIG. 3, an oscillator is used, which corresponds to an embodiment, and in addition, the illumination of the LED and the OLED may be controlled through various current control. For example, a triangle signal is generated using a triangle wave generator, a waveform such as 336 of FIG. 3 is generated through a comparator, and the signal of the generated waveform is dimmed. Dimming control can also be performed by

In the case of dimming through current control of LED, OLED, etc., illumination can be controlled by repeatedly turning on and off depending on the characteristics of the lighting. Therefore, a circuit for generating a waveform of a format such as 336 and implementing a current through the illumination with the waveform is included in the current controller according to an embodiment of the present specification.

4 is a diagram illustrating a configuration of a voltage controller according to an embodiment of the present specification. The central controller provides a control signal to the timer 420 as shown in 410. The control signal provided to the timer 420 causes the voltage controller 400 to hold the power supply DC 24V until a voltage level required for dimming adjustment is reached. In one embodiment of the control signal provided to the timer, it may be a zero crossing voltage pulse, and the timer 420 is triggered by the zero crossing voltage pulse. The timer 420 may repeat the trigger / reset at a predetermined interval, and may be implemented to adjust the dimming of the illumination.

Multiple resistors and conductors can be used to apply the correct voltage level to the IGBT 430. When the voltage applied to the gate of the IGBT 430 reaches a predetermined level, the gate of the IGBT 430 becomes low and turned off, and the timer 420 may be reset. In this process, the voltage distributed through the plurality of diodes of the voltage divider 440 in the IGBT 430 is output to the dimming selector as shown in 450. The overcurrent protection unit 435 prevents overcurrent from being applied to the IGBT 430.

 The voltage controller 400 of FIG. 4 is an exemplary embodiment, and may be implemented in various ways. When the voltage applied to the IGBT element reaches a predetermined level, the controller or timer for applying the voltage to the IGBT is reset. In this process, IGBT is also turned off. When the controller or the timer is triggered again after a predetermined time, a voltage is applied to the IGBT, and the applied voltage is output to the dimming selector as shown in 450. As such, the voltage is output to the dimming selector to adjust illumination of the illumination by turning on / off the IGBT and the timer or controller.

In addition to the embodiment of FIG. 4, a reverse phasing signal may be used in the voltage controllers 140, 242, and 244. For example, in the case of a halogen lamp, an antiphase signal of the voltage controller may be a signal for adjusting dimming. In an embodiment of the method of controlling by using an antiphase, two IGBTs are continuously triggered using a timer having a predetermined time interval (for example, 5 ms) by using a PWM signal output from the central controller. IGBT can be controlled. In this case, an over current protection circuit for protecting the timer circuit, the antiphase and the IGBT element may be included.

In addition, another embodiment of the voltage controller 140, 242, 244 may include a constant voltage smoothing circuit. In the case of the constant voltage control, the constant voltage smoothing circuit may be implemented in the voltage controller to prevent the waveform from being distorted and noise when dimming the DC input voltage. In one embodiment of the signal such as 410 may be a PWM signal and an analog signal.

Another embodiment of the voltage controller may include a D / A comparator. This is a kind of D / A converter, and the dimming control can be performed depending on whether the fluorescent lamp to be adjusted for dimming is analog or digital. That is, a DC-0-10V analog signal, which is a control method of a dimming ballast of a fluorescent lamp, may be a signal for adjusting dimming.

Although the power input in FIGS. 3 and 4 is described as DC 24V, this corresponds to an embodiment and may be variously selected according to the lighting and power system to be implemented.

5 is a diagram illustrating a detailed configuration of a dimming selector according to an exemplary embodiment of the present specification.

The dimming selector 520 provides a function of selecting illuminance to be provided by the current and voltage controllers 130 and 140 and lighting to perform the dimming control in a plurality of circuits. The illumination controlled by the lighting system may be set in advance whether the illumination is adjusted by the current control or the voltage control, but may be changed according to the installation situation of the lighting. That is, the lighting by the voltage control may be installed again where the lighting by the current control is installed, and vice versa. Therefore, the dimming selector 520 may control the lighting and the current and the voltage for the lighting appropriately through the switching function of the circuit.

The main configuration of the dimming selector 520 is an interrupt selector 521. The interrupt selector 521 controls a plurality of dimming control signals and which output ports are connected to these dimming control signals to adjust dimming of the lighting.

A physical address (physical address) is a type of dip switch that sets which light is used for which port in a light installation or light change phase. And setting the type of illumination to be connected to the multi dimming output port 580. For example, LEDs are used for the first and second ports (No 1 Port, No 2 Port) of the multi dimming output port 580, and halogens are used for the third, fourth, and fifth ports (No 3 Port, No 4 Port, and No 5 Port). If the lighting is set and the fluorescent lamp is installed in the 7th to 16th ports (No 7 ~ 16 Port), the setting information about this can be assigned a physical address in the form of a dip switch. The physical address can be changed and set at the installation site of the illumination control system. In addition, when the lighting is changed, for example, when changing the LED lighting installed in the first port (No1 port) to halogen lighting can change the physical address. The change information is also applied to the translation lookaside buffer (TLB) of the central control unit 110 to adjust the lighting from the outside. The physical address (dip switch) is an embodiment, and not a physical setting, but may be implemented only by the central controller 110.

In order to adjust the illuminance of the illumination, various dimming control signals may be received according to the characteristics of the illumination. The current controller 300 and the voltage controller 400 have been described above as an embodiment of the illuminance controller. In the current controller 300, the constant current and the voltage controller 400 may be the signals 339 and 450 of the exemplary embodiment described with reference to FIGS. 3 and 4 to the interrupt selector 521 as a dimming control signal.

A dimming control signal such as a constant current or a constant voltage is input to the interrupt selector 521, and the interrupt selector 521 selects based on the physical address to which illumination the input signal is transmitted. The selected dimming control signal is sent to the port to which the corresponding light is connected to adjust the dimming of the light connected to the corresponding port.

The physical address contains information for switching the output to the dimming signal and the illumination. In another embodiment of the present specification, such information may be implemented to enable setting from the outside. Non-volatile memory devices that store information even when power is not supplied can be used to externally set the illumination and the illumination control unit for the illumination.

The multi-dimming output port 580 of FIG. 5 may be implemented inside the dimming selector 520 or may be separately implemented. This may be implemented differently depending on the distance between the dimming selector and the lighting, or depending on the size of the illumination control system of the present specification.

The dimming selector 520 of FIG. 5 receives two or more illuminance control signals for adjusting the illuminance of the illumination from an illuminance control unit such as a current control unit or a voltage control unit, and applies the two or more illuminance control signals thus received to the corresponding illumination. To provide. In addition, the switching information between the illumination and the illumination control signal may be set and stored or changed so that the illumination control signal of the current controller or the voltage controller may be appropriately applied according to the characteristics of the plurality of illuminations. As described above, it may be configured in a dip switch type and configured to be stored in a nonvolatile memory through an external device. The dimming selection unit of the present specification may be configured independently and may be used in combination with a plurality of illumination control units. Also, the dimming selector may optionally include a multi dimming output port, and a plurality of dimming selectors may be included in one illumination control system.

6 is a diagram illustrating a configuration of an external input device according to an embodiment of the present specification.

An example in which the external input device 170 of FIG. 1 may be implemented is shown in more detail. Description of the same components is replaced by the description of FIG. 1. The external input devices 670a, 670b, 670c, 670d, and 670e may provide an interface for controlling the illumination of the illumination and information for confirming the illumination state of the illumination. Various external input devices can be implemented according to the characteristics of the space installed in the lighting.

The central control monitoring device 670a is distributed in the number of lights to be adjusted in the building, it can be built in a large building difficult to grasp the situation of the light inside the building. The central control monitoring device 670a may store the characteristics of the lights to be controlled, the current state of the lighting to be controlled, and scenarios necessary for adjusting the illumination, and such information may be stored in the central control monitoring device 670a to store the manager. Various lights in the building are controlled according to the direct execution of the event or the scheduled execution by the timer. The central control monitoring device 670a may be combined into one or more computers so that the computers may be connected to a network, and may be installed in each floor of a building to adjust illumination by mutual communication. For example, lighting on the 20th floor can be controlled by a computer on the first floor connected to the central control monitoring device 670a. The contents connected to the central control monitoring device 670a provide a respective information, and are configured in a network so that they can be checked by a plurality of computers. Also, information inputted through the plurality of computers is also transmitted through the network. This is because it is stored in 670a to perform lighting control.

The touch screen 670b may be built in a medium or small building in which the number of lights is distributed in the building, but the size of the building is not large. The touch screen 670b may also store the characteristics of the lights to be controlled, the current state of the lights to be controlled, and scenarios for the illumination adjustment, and the administrator executes the illumination adjustment through the touch screen in real time or pre-stored scenarios. Depending on the time, you can adjust the illumination of the lights in the building by running a reservation at that time. The touch screen 670b is useful when it is possible to check all the lights in the building within one screen. Of course, the touch screen 670b may also be configured as a computer of the central control monitoring device 670a to control lighting of a large building.

Keypad 670c is suitable for controlling home lighting. When the number of lights that can be controlled is around 10, since the number of cases that occur in the detailed setting and scenario setting for the lighting is not large, it can be easily set for each lighting. In addition, since there are not many kinds of specific scenarios, setting or execution of the corresponding scenarios may also be performed through the keypad 670c.

The keypad 670c may also be a component of the central control monitor 670a or the touch screen 670b. That is, the central control monitoring device 670a or the touch screen 670b manages the whole building, and the keypad 670c may be configured to manage only lighting of a specific area of the building.

The remote switch 670d is a switch for remotely controlling the light, and may be configured in combination with the central control monitor 670a, the touch screen 670b, or the keypad 670c, and remotely controls a small number of lights. It can be configured to.

Similarly, the IR / RF remote controller 670e may also be configured in combination with the central control monitoring device 670a, the touch screen 670b, or the keypad 670c.

The remote switch 670d and the IR / RF remote controller 670e may be combined with a few lights to remotely adjust the illumination of the lights. In addition, in the case of the IR / RF remote controller 670e, various lightings may be controlled without being limited to specific lighting. Therefore, the IR / RF remote controller 670e for controlling the lighting of the first floor may be moved to the 20th floor to control the lighting.

The external input devices 670a, 670b, 670c, 670d, and 670e transmit information or signals to the external input receiver 650 to adjust illumination of illumination. The external input receiver 650 may provide various interfaces according to the characteristics of the external input device. For example, interfaces such as RS232, RS485, and DMX512 can be used. Each interface is as follows.

RS232 is a serial communication standard that sends signals one bit at a time and is suitable for 1: 1 communication, while RS485 supports longer distance communication than RS232 and can be connected to multiple devices.

DMX512 (Digital MultipleX) is an international communication standard that can be used with equipment related to light sources. 512 control channels are available per data link, which allows you to adjust the lamp dimming.

Therefore, when using an interface such as RS232, RS485, or DMX512, a signal received from an external input device is transmitted to the central controller 110 so that the central controller 110 can control the current controller 130 or the voltage controller 140. To help.

The external input devices 670a, 670b, 670c, 670d, and 670e not only adjust the current lighting but also store information to adjust the illumination of the lighting under a certain time or under certain conditions, so that the illumination according to the corresponding time or under such conditions It includes a configuration for transmitting information to the central control unit 110 to adjust. To this end, the external input device may include a predetermined information storage unit. For example, since the central control supervisor can be connected to a plurality of computers, it is possible to store and maintain the information necessary to adjust the illumination of the illumination using a database or a file storage device in the computer.

In addition, the touch screen, keypad, etc. may also include a memory device, which stores information on the illumination control of a specific light, so that the central controller 110 can control the illumination of a specific light at a specific time / condition. have.

7 is a diagram illustrating a configuration of a sensor interface according to an exemplary embodiment of the present specification.

In the embodiment of FIG. 1, a dimming system for multi-illumination may be implemented by adding a sensor interface. The sensor interface works with sensors that determine the external lighting environment, emergency, or whether the lights should be turned on. In Fig. 7, a plurality of sensors 791a, 791b, ..., 791n are provided. One embodiment of the sensor may be an optical sensor, an illuminance sensor, a fire sensor, a human body sensor, a temperature sensor, or the like. The optical sensor may detect light coming from the outside, for example, sunlight, and transmit information about the detected light to the central controller 110 through the sensor interface 790. The central controller 110 may adjust the illuminance of the lighting of the corresponding space according to the amount of external light. For example, for a light set to maintain light at A level during the day, if the amount of light coming from outside is small, keep the light at B level (B is darker than A) at night. Illumination can be adjusted.

When using an illuminance sensor, when the illuminance decreases according to the life of the light, the illuminance of the corresponding light may be increased. For example, assume that the illuminance sensor is 791a, and the illuminance sensor senses the illuminance of the illumination 160a. Although the illuminance sensed by the illuminance sensor 791a is B level, the illuminance to be provided by the originally set 160a light may be A level (A is brighter than B). When the usage period of the illumination 160a is prolonged and aged, the illuminance of the illumination becomes dark even if the amount of current or voltage is maintained as it is. The illuminance sensor 791a senses the illuminance of the illumination 160a and transmits the sensed illuminance information to the central control unit 110 through the sensor interface 790. The central control unit 110 receives less illuminance information of the received light than the original setting. In this case, the illumination of the lighting can be increased or adjusted.

In the case of a fire sensor, the intensity of illumination can be adjusted for emergency evacuation in case of fire. When a fire has occurred in a specific space and the fact that such a fire is transmitted through the fire sensor and the sensor interface unit 790, the central control unit 110 may adjust the illuminance of the lighting to enable evacuation in case of fire.
