Description

Hybrid dimming control system for LED lamp which supports SMPS of constant-current and constant-voltage type and method

The present invention relates to a hybrid dimming control system and method, and more particularly, to a hybrid dimming control system and method for an LED lamp that supports a constant current and a constant voltage switching mode power supply (SMPS).

In addition to the development of the lighting industry with the advancement of the technology, the development of the dimming control device that can precisely adjust the desired brightness beyond the method of controlling the lighting with simple ON and OFF has become prominent.

Currently, the dimming control device is provided by dividing the operation method of the constant voltage and the constant current. The dimming control device operated by the constant voltage method is provided for widespread use such as home and office because the dimming control is easy, and the dimming control device operated by the constant current method enables more precise dimming control than the constant voltage method, while the brightness is higher than a certain level. In case of crossing, it shows abnormal output, so the dimming step is very limited, so it is used for turning on and off by lighting at a constant current, not for dimming control.

Therefore, the manufacturer of the dimming control device manufactures the dimming control device by dividing the constant current and the constant voltage method according to the use.

Despite the above-mentioned problems, the advantages of energy saving efficiency due to the precise dimming control of the constant current over the constant voltage method have been recently combined with the energy saving policy. Attempts are increasing.

However, the constant voltage dimming control device can easily fix the voltage to limit the use range so that no abnormal output occurs, but the constant current dimming control device is difficult to fix to a specific value due to the characteristics of the current, so the brightness is high. In the case of exceeding a certain amount, the amount of current rapidly increases to exceed the range of use supported by the dimming control device, thereby causing an abnormal output as described above.

This abnormal output is transmitted to the load connected to the dimming control device of the constant current type as it increases the heat generation of the load, thereby reducing the life and at the same time a problem that the advantage of energy saving efficiency is lost.

Therefore, in order to improve energy saving efficiency, dimming control can be made to stably support constant current dimming control that supports precise dimming control, while supporting both constant voltage and constant current methods to improve the versatility and compatibility, thereby reducing the manufacturing cost burden of the manufacturer. Development of the system is required.

An embodiment of a hybrid dimming control system and method for an LED lamp supporting a constant current and a constant voltage switching mode power supply (SMPS) according to the present invention will be described in detail with reference to the drawings.

1 is a configuration embodiment of a lighting control system to which a hybrid dimming control system for an LED lamp supporting a constant current and a constant voltage SMPS according to the present invention is applied. As shown, the lighting control system includes a lighting server 10 and a local lighting unit 100. The lighting server 10 may be connected to the local lighting unit 100 by a power line and a control line.

The lighting server 10 transmits a dimming control signal to the local lighting unit 100 through the control line, and the local lighting unit 100 uses the power signal according to the dimming control signal received through the control line. The brightness of the light emitting unit 130 configured in the local lighting unit 100 may be controlled by adjusting the received power.

Referring to the detailed configuration and dimming control operation of the local lighting unit 100 on the basis of the above, first, the local lighting unit 100 is composed of SMPS (110), dimmer (120), light emitting unit (130) The wireless communication unit 140 and the sensor unit 150 may be additionally configured.

In this case, the SMPS 110 may convert the AC power received through the power line into DC power, which is a driving power, and provide the same to the dimmer 120, and independently of the lighting server 10 without the connection. It may be connected to the dimmer 120 to provide driving power.

In addition, the dimmer unit 120 may be connected to the lighting server 10 through a control line to perform wired communication, and a dimming control signal received through the control line among a plurality of dimming steps divided by different brightnesses. A pulse width modulation (PWM) signal corresponding to the dimming step may be generated and provided to the light emitting unit 130. Accordingly, the light emitting unit 130 may have brightness corresponding to the dimming control signal according to the PWM signal. Is driven.

On the other hand, the light emitting unit 130 may be composed of a driver 131 and the lighting load 132, as shown, the driver 131 by adjusting the power of the SMPS (110) in accordance with a PWM signal to the Configured to control the brightness of the lighting load 132. In this case, when the bypass unit configured to bypass the power provided by the SMPS 110 is configured in the dimmer unit 120, the driver 131 supplies the driving power of the SMPS 110 through the dimmer unit 120. It may be provided, or may be directly connected to the SMPS 110 to receive power.

In this case, the lighting load 132 may include a fluorescent lamp, a halogen lamp, an incandescent lamp, etc., but it is preferable that an LED lamp suitable for energy saving efficiency is configured.

Based on the dimming control configuration and operation described above, the wireless communication unit 140 and the sensor unit 150 may be additionally configured in the local lighting unit 100.

That is, the dimmer unit 120 may receive the wireless dimming control signal from the lighting server 10 or the external control device through the wireless communication unit 140 to perform the above-described dimming control operation, and the sensor unit 150. It may be operable to control the brightness of the light emitting unit 130 by detecting a predetermined object through.

In the configuration of such a lighting control system, the SMPS 110 is configured to support a constant voltage method or a constant current method.

At this time, the existing dimmer unit 120 is configured to correspond to any one of the constant voltage or the constant current driving method of the SMPS 110, it is difficult to configure the dimmer unit 120 that supports both the constant voltage and the constant current. .

4 (a) and 4 (b), the dimmer part gradually increases the dimming step according to the dimming control signal, thereby approaching the maximum output of the SMPS 110. Even though providing the constant voltage method, as shown in FIG. 4 (a), since the dimming voltage is fixed according to the dimming step, the current provided from the driver 131 to the lighting load 132 is fixed. Accordingly, in the constant voltage method, stable power is provided in each dimming step.

On the other hand, in the constant current method, the current is fixed in the dimming step. Unlike the voltage, the current is difficult to be fixed constantly. Thus, as shown in FIG. 2B, the dimming step is increased to approach the maximum output of the SMPS 110. At a certain point in time, the amount of current that the driver 131 provides to the illumination load instantly increases and an abnormal section exceeding the maximum output supported by the SMPS 110 occurs. That is, in the constant current method, since the voltage is not fixed, the driver 131 is not limited to the amount of current drawn from the SMPS 110, and thus an abnormal section occurs as described above.

Since the occurrence of the abnormal section is overloaded the lighting load 132, not only the lighting load 132 but also the overall heat generation of the local lighting unit 120 is increased to shorten the life of each component of the local lighting unit 100, power Consumption increases and energy efficiency drops drastically.

Therefore, the SMPS 110 of the constant current method has a problem as described above, but can fix the current outside the abnormal section, so that the energy efficiency is higher than that of the constant voltage method at the same output, so it is not dimming control (ON / OFF). Used for the purpose.

However, due to the high energy saving efficiency due to the fixed current, which is an advantage of the constant current method, attempts to apply it to the dimming control have been increasing, and the present invention provides a system configuration for easily applying the constant current to the dimming control. At the same time, it allows both constant voltage and constant current to be supported in one system.

Hereinafter, an embodiment of a hybrid dimming control system for an LED lamp supporting a constant current and a constant voltage SMPS according to the present invention integrating a constant voltage and a constant current method will be described in detail with reference to FIG. 2.

FIG. 2 is a conceptual view illustrating an operation of the dimmer unit 120 configured with a hybrid dimming control system for an LED lamp that supports a constant current and a constant voltage SMPS according to an embodiment of the present invention. As shown in FIG. An initial setting according to the specification of 110 is input, and the output of each dimming step is scanned by monitoring the output of the light emitting unit 130 for the entire dimming section consisting of a plurality of dimming steps in the initial operation according to the initial setting. To work.

The scan process operates when the initial setting is a constant current method. In the constant voltage method, since the above-described abnormal section does not appear, the scan process may be omitted and the light emitting unit 130 may be directly controlled by the dimming control signal received from the lighting server 10. Dimming control operation may be made.

On the other hand, the initial setting input to the dimmer unit 120 is for either one of the constant current or the constant voltage through a dip switch configured in the dimmer unit 120 or a setting control signal received from the lighting server 10. Settings and settings for voltage, power, and maximum output of the SMPS can be input.

Thereafter, the dimmer unit 120 transmits a PWM signal for each dimming stage to the driver 131 of the light emitting unit 130 based on the initial setting, and monitors the driver 131 to monitor the dimming stage PWM signal. The scan process may be performed to detect an output corresponding to.

Through the scanning process, the dimmer 120 may easily detect the abnormal section in the constant current method.

The hybrid dimming control system for LED lamps supporting the constant current and the constant voltage SMPS according to the present invention can support the stable dimming control in the constant current method by processing the abnormal section in a unique manner according to the detection of the abnormal section. An example will be described in more detail based on the detailed configuration of the hybrid dimming control system for the LED lamp supporting the constant current and the constant voltage SMPS according to the present invention configured in the dimmer unit 120 of FIG. 3.

3 is a detailed configuration diagram of a hybrid dimming control system for an LED lamp that supports a constant current and a constant voltage SMPS configured in the dimmer unit 120. The control unit 121, the setting unit 122, The monitoring unit 123 and the communication unit 124 may be configured, and an operation mode according to the sensor interface unit 125 and the sensor unit 150 interoperating with the sensor unit 150 and an operation according to the communication unit 124. The mode selector 126 for selecting at least one of the modes may be additionally configured. The additional configuration will be described in detail with reference to FIGS. 8 to 11.

First, the function described with reference to FIG. 2 will be described in correspondence with each component, and the setting unit 122 may correspond to the dip switch as a configuration for receiving the initial setting. That is, the setting unit 122 may input the setting for any one of the above-described constant current or constant voltage, and the setting for the voltage, power, and maximum output of the SMPS 110.

In addition, the controller 121 may generate a PWM signal for each dimming stage based on the initial setting input through the setting unit 122 and provide the PWM signal to the driver 131 of the light emitting unit 130. In this case, the control unit 121 may receive a setting control signal of the lighting server 10 through the communication unit 124 to receive an initial setting, and configure the setting unit 122 as a memory to the corresponding memory. The initial setting received from the lighting server 10 may be stored and a PWM signal may be generated for each dimming step based on the initial setting.

Thereafter, the controller 121 may scan the output of the light emitter 130 according to the dimming PWM signal. That is, when the controller 121 transmits the dimming PWM signal to the driver 131 of the light emitting unit 130, the monitoring unit 123 may be a driver of the light emitting unit 130 corresponding to each PWM signal. The controller 131 detects an output appearing from the driver 131 and provides it to the controller 121, and the controller 121 may scan an output corresponding to a PWM signal for every dimming step.

4 (a) and 4 (b) show outputs according to PWM signals according to dimming steps in the constant voltage method and the constant current method according to the scan operation of the controller 121. As shown in FIG. In FIG. 4A, which is an output of the constant voltage method, the abnormal section does not appear, and thus the dimming control can be performed immediately by omitting the aforementioned scan process.

On the other hand, when it is set in the constant current method according to the initial setting, the control unit 121 performs a scanning process as shown in FIG. Excess abnormal section can be detected.

This abnormal section can determine the abnormal state by type by calculating the power factor using the power, voltage, maximum output (load or no load output, manufacturer-supplied maximum output value, etc.) provided according to the setting.

For example, if the constant current output is 5A and the maximum output is 33V, the monitored output is below 5A or above 33V, below 33V or above 5A, above 5A and above 33V, etc. May be determined as an abnormal section.

In FIG. 4B, an abnormal section is detected in a 70-95% section of the maximum dimming step (maximum brightness), and it can be seen that normal dimming control is not performed in the corresponding section.

Accordingly, the controller 121 may reconfigure the dimming control section by deleting the abnormal section as shown in FIG. 4C to support stable dimming control in the constant current method. That is, the controller 121 deletes 70 to 95% of the dimming step corresponding to the abnormal period, and dimming after the 69% dimming step when the dimming step before the 70% dimming step is the 69% dimming step. The entire dimming interval can be reconstructed so that is a dimming step of 96%.

In this case, when the dimming section is reconfigured after the abnormal section is deleted, the existing dimming step may be ignored and the entire dimming section may be repartitioned into different dimming steps. For example, when the control unit 121 is 8 bits, the dimming step may be reconfigured by subdividing the dimming step into 256 sections.

As described above, the controller 121 may perform dimming control in the reconfigured dimming section, and if a dimming control signal corresponding to an abnormal section is received, ignores it and transmits a PWM signal to the driver 131. The PWM signal of the dimming step may be transmitted to the driver 131 of the light emitting unit 130 by resetting the dimming step corresponding to the dimming control signal among the dimming steps included in the dimming period which is not performed or reconfigured.

Meanwhile, since the abnormal section differs according to the specifications of the light emitting unit 130 and the SMPS 110, the controller 121 shows that the abnormal section is represented as one (A) as shown in FIG. 5A. In addition, as shown in FIG. 5B, when a plurality of abnormal sections B and C occur, the dimming sections may be easily reconfigured by deleting the corresponding abnormal sections.

As described above, the output of the abnormal section no longer occurs, so that stable dimming control can be achieved, and a higher energy saving efficiency can be guaranteed than the constant voltage method through the dimming control of the constant current method.

It also supports constant voltage dimming control for versatility and compatibility.

Based on the above-described configuration, the hybrid dimming control system for LED lamps supporting the constant current and the constant voltage SMPS according to the present invention detects an abnormal output even during the dimming control operation according to the reconfigured dimming interval, and then reconfigures the dimming interval. By reconfiguring again, it is possible to prevent energy efficiency degradation or abnormality of the local lighting unit 100.

For example, during the dimming control of the light emitting unit 130 with the PWM signal corresponding to the specific dimming step in the reconfigured dimming period, an output corresponding to the specific dimming step due to an abnormal occurrence of the SMPS 110 and the When a difference in output detected by the light emitter 130 is greater than or equal to a preset level, the controller 121 may reconstruct the reconstructed dimming section by repeating the above-described scan.

In this case, when the abnormal section is not detected as a result of the scan, the controller 121 determines that the simple section is in use and maintains the existing dimming section. On the other hand, if the abnormal section is detected as a result of the scan, the controller 121 may reconstruct the reconstructed dimming section by deleting the abnormal section.

In addition, when the abnormal output is detected through the monitoring unit 123 during the dimming control operation, the controller 121 provides the occurrence information to the lighting server 10 through the communication unit 124 to generate an abnormality. The local lighting unit 100 may be easily determined.

FIG. 6 is a flowchart illustrating reconfiguration of a dimming section in a constant current method through scanning of the dimmer unit 120 in which a hybrid dimming control system for LED lamps supporting constant current and constant voltage SMPS is configured according to an embodiment of the present invention. As described in the example, the specification of the SMPS 110 by local setting through a dip switch configured in the dimmer unit 120 or remote setting through the lighting server 10 connected to the dimmer unit 120 before the initial operation ( Voltage, power, maximum output), and any one of a constant current or a constant voltage method may be initially set in the dimmer unit 120.

Subsequently, the dimming unit 120 may directly perform dimming control without a scanning process in the case of the constant voltage method. In the case of the constant current method, the dimming unit 120 determines an abnormal section through the above-described scanning process, and dims to the remaining sections except for the abnormal section. The interval can be reconstructed. Accordingly, the dimming unit 120 equally divides the reconstructed dimming interval to generate a plurality of dimming stages, and emits a PWM signal of the dimming stage corresponding to the dimming control signal received from the lighting server 10. The light emitting unit 130 may emit light at the brightness according to the dimming step by transmitting to the 130.

Meanwhile, FIG. 7 is a flowchart illustrating an operation of the dimmer unit 120 when an abnormal output is detected in illumination during the dimming control operation according to the dimming interval reconfiguration of FIG. 6. As illustrated, the dimmer unit 120 is dimmed. 6, when the output of the light emitter 130 is continuously monitored during the dimming control operation according to the section reconstruction, the output corresponding to a specific dimming step and the output detected by the light emitter 130 are different from each other by a predetermined level or more. By repeating the process, an abnormal section in which an abnormal output occurs may be detected, and a dimming section may be configured as the remaining sections except for the abnormal section. That is, the dimming interval reconstructed through the initial scan may be reconstructed.

Accordingly, even when an abnormal output occurs during the dimming control operation of the constant current method, it is possible to easily cope with it, and by removing the corresponding abnormal section through a scan to achieve a stable dimming control.

8 to 11 illustrate embodiments of a lighting control system including a plurality of dimmers 120 to which a hybrid dimming control system for an LED lamp that supports the above-described constant current and constant voltage SMPS is applied.

First, referring to FIG. 8, a plurality of local lighting units 100 including the dimmer unit 120 may be connected to the lighting server 10 through a power line and a control line. In this case, the dimmer unit 120 supporting both the constant voltage and the constant current method may be connected to the SMPS 110 to unify the SMPS 110 configured in the plurality of local lighting units 100 into either the constant voltage or the constant current method. It is possible to configure the SMPS 110 in a different manner without the need.

In addition, the dimmer unit 120 may support wireless communication through the communication unit 124 connected to the wireless communication unit 140 configured in the local lighting unit 100 as shown in FIG. 3.

Accordingly, as illustrated in FIG. 9, the plurality of dimmers 120 are individually separated from the lighting control means through the wireless communication unit 140 from the lighting control means 200 for transmitting the dimming control signal in a wireless communication method. In communication, the dimming control signal may be received. Through this, each dimmer 120 may be independently controlled in accordance with the dimming control signal.

In addition, by integrating the configuration of FIG. 8 and the configuration of FIG. 9, any one of the dimmers 120 of the plurality of dimmers 120 may be the lighting control means (for example, a wired or wireless remote controller). When the dimming control signal is received through the wired / wireless communication from the 200, the dimmer unit 120 that receives the dimming control signal relays the corresponding dimming control signal through the wireless communication unit 140 or another dimmer unit through the control line ( 120). In addition, another dimmer 120 receiving the dimming control signal through the relayed dimming control signal or the control line may also relay the same dimming control signal or transmit the same to the adjacent dimmer 120 through the control line.

Accordingly, even if the lighting control means 200 transmits a dimming control signal to one adjacent dimmer 120, the plurality of dimmers 120 may be integratedly controlled according to the corresponding dimming control signal.

In addition, the dimmer unit 120 includes an interface 125 that communicates with the sensor unit 150 configured in the local lighting unit 100, as illustrated in FIG. 3, and controls the control unit 121 of the dimmer unit 120. ) May generate a predetermined PWM signal according to the detection signal of the sensor unit 150 and transmit the generated PWM signal to the light emitting unit 130.

According to this configuration, as illustrated in FIG. 11, the dimmer unit 120 that receives the detection signal generated according to the detection of the object 300 of the sensor unit 150 performs dimming control based on the detection signal. It can be carried out. In this case, when the detection signal of the sensor unit 150 is no longer received, the dimmer unit 120 stops the generation of the PWM signal to turn off the light emitting unit 130 or set an initial setting before reception of the detection signal. The PMW signal, which is a value, may be output to illuminate with a lower illuminance than the illuminance when the detection signal is received.

Accordingly, as shown, when the object 300 moves, the dimmer 120 configured in the local lighting unit 100 located in the moving path of the object 300 performs dimming control to move on the moving path of the object 300. The light emitting unit 130 located in the light emitting unit 130 may operate to emit light, and the dimmer unit 120 in which the object 300 is no longer detected by the object 300 is turned off so that the light emitting unit 130 is turned off to reduce energy efficiency. It can increase.

In addition, the dimmer unit 120 receiving the detection signal of the sensor unit 150 may transmit a dimming control signal to the dimmer unit 120 configured in the adjacent local lighting unit 100 through the wireless communication unit. The adjacent dimmer 100 receiving the dimming control signal may perform dimming control on the light emitter 130.

That is, the plurality of dimmers 120 adjacent to the point where the object 300 is detected may light up the light emitter 130 to increase the peripheral illumination of the object 300.

In addition, by combining the configuration of Figure 10 and 11, the dimmer 120 receiving the detection signal of the sensor unit 150 may transmit the detection signal to the lighting server 10 via a control line, The lighting server 10 may determine the movement path of the object according to the detection signal to control the dimmer unit 120 located on the movement path to turn on or dimm the light emitting unit 130.

In addition, the lighting server 10 controls the dimmer unit 120 based on the detection signal to determine that the object is out of the position of the corresponding dimmer unit 120, or first turns off after a predetermined time elapses. The controlled dimmer 120 may be sequentially turned off.

Meanwhile, as shown in FIG. 3, the dimmer unit 120 includes a mode selector 126 for selecting at least one of an operation mode according to the sensor interface 125 and an operation mode according to the communication unit 124.
