1 is a block diagram illustrating a color synchronization system of a multi-luminaire according to the present invention.

Referring to the drawings, in the color synchronization system of the multi-luminaire, a plurality of slave illuminators 200 are connected to the master illuminator 100 via the control signal line 103.

The master lighting device 100 includes a color light generating unit 110 and a master controller 120.

The color light generating unit 110 is configured to emit light emitted from the light source sequentially to the optical fiber bundles by using the color pillar wheels.

One embodiment of the color light generating unit 110 is shown in FIG.

Referring to FIG. 2, the color light generating unit 110 includes a case 111, a light source 113, a reflector 114, an IR filter 115, a color filter wheel 116, and a motor M 117 as a driving source. ), An optical fiber bundle 118.

The light source 113 is provided in the case 111. Although not shown, a cooling fan for cooling the heat generated by the light source 113 may be installed.

Reflector 114 is applied to be able to reflect and focus the light emitted from the light source 113 to the optical fiber bundle 118.

The reflector 114 may be an ellipsoidal or parabolic mirror.

Although not shown, a collimating lens for focusing the light reflected by the reflector 114 may be further provided.

An IR filter (Infra Red Filter) 115 is provided in front of the reflector 114.

The IR filter 115 blocks infrared rays and ultraviolet rays, which are harmful to the human body and the irradiated object, among the light of the wide wavelength range emitted from the light source 113 to transmit only visible light.

The color filter wheel 116 is configured to sequentially transmit and transmit color light of different colors among visible light emitted through the IR filter 115 by the rotation of the motor 117 which is a driving source.

The color filter wheel 116 may have a structure in which a color filter for filtering a circular disk made of a transparent material to a plurality of sectors separated at equal intervals along the radial direction may be applied.

That is, referring to FIG. 3, which is illustrated as an embodiment of the color filter wheel 116, the color filter wheel 116 has four sectors divided into four at 90 degree angles, and the first sector 116a has an IR filter. A second filter 116b is provided with a red filter, a third filter 116c is provided with a green filter, and a fourth color filter 116d is provided with a blue filter.

The number of sectors and the filter colors applied to the color filter wheel 116 may be variously applied differently from the illustrated example.

For example, the number of sectors of the color filter wheel 116 can be applied in six divisions, eight divisions, and the like. In addition, the color filter applied to each sector is also applied with cyan, magenta, green, and IR filters for 4 divisions, and cyan, magenta, green, IR filters, purple, orange, yellow, and dark blue filters for 8 divisions. Can be.

In the drawing, reference numeral 119 is formed at the origin position set to synchronize the color filter wheels 116 and is formed to protrude a predetermined length from the sector boundary region as an identification mark member for detecting rotation.

The identification mark member 119 may be formed on the color filter wheel 116 to correspond to the origin detection sensor 130 to be applied.

The home detection sensor 130 detects whether the identification mark member 119 has reached the set home position, and outputs a signal corresponding to the detection.

The origin detection sensor 130 may be applied in various ways, for example, a hall sensor, a magnetic sensor, or the like, depending on the identification mark member to be applied. In the illustrated example, a photo interrupter is applied.

That is, as shown in an enlarged view of FIG. 4, the origin detection sensor 130 includes a light source 131 and a photodetector 132 installed in a direction crossing the rotation trajectory of the identification mark member 119. The light source 131 and the photodetector 132 are spaced apart from each other in the recessed housing 133 to shield entrance of external light.

The installation position of the identification mark member 119 and the arrangement structure of the origin detection sensor 130 reduce the interference effect of the light emitted from the light source 131 to the photodetector 132 and thus the identification mark member 119 of the photodetector 132. ) Detection errors can be reduced.

Meanwhile, as illustrated in FIG. 5, the master controller 120 includes a key operation unit 121 and a master control unit 140.

The key operation unit 121 is preferably provided with a mode selection key and an execution key.

The mode selection key is a key for selecting a synchronous mode and an independent mode, and the execution key is a key for selecting an operation and a pause.

Here, the synchronous mode controls the wheel driver 141 for driving the motor 117, which is the driving source of the color filter wheel, so that the slave luminaire 200 and the master luminaire 100 can emit colors of the same color. The independent mode is a mode for driving the color filter wheel 116 irrespective of the output signal of the origin detection sensor 130.

The slave controller 210 includes a key operation unit 211 and a slave control unit 240.

The key operation unit 211 is provided with a mode selection key for selecting the synchronization mode and the independent mode.

Of the control lines connected between the master control unit 140 and the slave control unit 240 in the drawing, the control signal line indicated by C1 is a signal line for transmitting an execution key setting signal, and the control signal line indicated by C2 is a drive resume signal for use in the synchronous mode. Is a signal line for transmitting a signal, and a portion denoted by G is a common ground signal line.

A circuit diagram according to a preferred embodiment of the master controller 120 and the slave controller 210 will be described with reference to FIGS. 6 and 10.

6 is a circuit diagram of a master controller according to a preferred embodiment of the present invention, and FIG. 7 is a waveform diagram of a portion of FIG. 6.

Referring to the drawings, the master controller 120 includes key operation units 121a and 121b, drive control unit 142, and synchronous mode execution units 144 and 145.

The wheel driving unit 141 is configured to supply and block driving power to the motor 117 according to a control signal output as a binary signal from the driving control unit 142. That is, the power supply loop to the motor 117 can be turned on / off depending on whether the light emitting diode 142a of the driving controller 142 is light-emitting.

In the drawing, reference numeral 105 denotes a power input terminal receiving a commercial AC power supply, and 107 denotes a power switch.

In the illustrated example, the wheel driving unit 141 can control the power supply / blocking loop to the motor 117 according to the presence or absence of the light emission signal from the light emitting diode 142a. It goes without saying that various ways in which supply / disconnection may be determined may be applied. In this case, the driving control unit 142 may be configured to output an electrical control signal to the wheel driving unit 141.

The key operation unit 121 is provided with an execution key 121a and a mode selection key 121b.

The run key 121a is connected to the other end of the power supply loop to the light emitting diode 142a of the drive control unit 142 by a switch for selecting one of the movable terminal RUN and the pause terminal PAUSE.

When the run key is connected to the run terminal RUN, the power supply of the light emitting diode path 142a through the transistor coupled to be self-biased by the power supply terminal VCC is supplied to the motor 117 according to the condition of the mode selection key 121b. Is ready to be activated / stopped.

When the execution key is connected to the pause terminal PAUSE, the power supply to the light emitting diode 142a is cut off and the driving of the motor 117 is stopped regardless of the condition of the mode selection key 121b.

The mode selection key 121b is connected to one end of the power supply loop of the drive control unit 142 to the light emitting diode 142a by a switch for selecting one of the independent mode, the synchronous mode, and the stop mode.

Therefore, when the execution key 121a is connected to the pause terminal PAUSE, the driving control unit 142 cuts off the power supply to the light emitting diode 142a, and when the execution key 121a is connected to the movable terminal RUN. The current supply loop to the light emitting diode 142a is turned on / off in accordance with the switch connection state of the mode selection key 121b.

As can be seen from the circuit diagram, when the mode selection key 121b is selected as the independent mode (cont.), The driving controller 142 detects the origin of the color filter wheel 116 according to the setting condition of the execution key 121a. Regardless of the output signal of the sensor 130 is controlled to be driven continuously or stopped.

On the other hand, when the mode selection key 121b is connected to the stop mode terminal stop, the driving of the color filter wheel 116 is stopped regardless of the operation of the execution key 121a.

When the mode selection key 121b is connected to the synchronous mode terminal sync, driving of the color filter wheel 116 is determined according to the signal level of the synchronous mode terminal sync and the setting state of the execution key 121a. That is, the driving of the color filter wheel 116 is stopped when the synchronous mode terminal sync is at a high level while the execution key 121a is set to the operating terminal RUN. It is operated to run.

The synchronous mode execution unit includes a stop signal generator 144, a delay signal generator 145, and a drive resume signal generator 146.

The stop signal generator 144 has a comparator 144a so that the comparator 144a can output a synchronization mode terminal sync at a low level or a high level depending on whether the photodetector 132 of the origin detection sensor 130 receives light. 132 is connected. Preferably, the comparator 144a is applied with an open collector type. Reference numeral 148 denotes a reference voltage generator for generating a reference voltage for inverting terminal input of the comparator 144a.

When the output terminal S of the photodetector 132 maintains the high level, the delay signal generator 145 switches the output terminal of the comparator 145a to a high level and is connected to the output terminal of the comparator 145a. ), The output signal gradually rises as shown in FIG. 7.

The stop releasing unit 146 is triggered when the output signal of the delay signal generating unit 145 rises above the reference signal of the comparator 146a and is connected to the output terminal OUT (D) of the IC 146b ( The output terminal E of the comparator 146d connected to the synchronous mode terminal sync by triggering the base of 146c is configured to be switched to the low level.

In the drawings, reference numerals C1 and C2 denote control signal lines connected to the slave controller 210.

In addition, as described above, in order to maintain the ground level with each other, the master control unit 140 and the slave control unit 240 preferably connect the common ground line G together with the control signal lines C1 and C2 together.

A case where the synchronous mode is selected for the operation of the master controller 120 will be described with reference to FIG. 8.

Herein, the synchronous mode selection state refers to a state in which the execution key 121a of the master controller 120 is selected as the operation mode RUN and the mode selection key 121b is selected as the synchronous mode sync.

The motor 117 is driven (step 100). That is, in the initial operation state in which the identification mark member 119 detection signal is not applied from the origin detection sensor 130, the synchronous mode terminal sync is kept low to drive the motor 117 of the master lighting device 100. The color filter wheel 116 rotates.

Thereafter, it is determined whether an origin detection signal indicating that the identification mark member 119 has arrived from the origin detection sensor 130 is input (step 110).

If it is determined in step 110 that the origin detection signal has been received from the origin detection sensor 130, the stop signal generator 144 is switched to the high level to stop the motor 117 (step 120).

After the motor 117 stops, it is determined whether the set delay time has been reached (step 130).

If it is determined that the delay time has been reached, a motor drive resume signal is generated (step 140). Then, the output signal of the stop release unit 146 is converted from high to low level, and the motor 117 starts to rotate again.

Meanwhile, a circuit diagram of the slave controller 210 according to the preferred embodiment of the present invention is shown in FIG.

In the drawings, elements having the same functions as shown in the previous drawings are denoted by the same reference numerals.

Referring to the figure, the comparator 246a is connected to the gate terminal of the transistor 242b of the drive controller 242 so as to receive the first control signal C1 and is connected to the synchronous mode terminal of the motor stop canceller 246. The non-inverting input terminal of X) is configured to receive the second control signal C2.

Therefore, when the mode selection terminal 121b of the slave controller 210 is selected as the independent mode (cont.), It is operated in conjunction with the operation of the execution key 121a of the master controller 120, and is synchronized. If it is selected, the operation is performed according to the operation of the executor 121a of the master controller 120 and the second control signal C2 of the master controller 120.

The operation of the slave controller 210 in the synchronous mode is shown in FIG. 10.

If the master controller 120 is set to the run mode (RUN), and the mode selection key 121b of the slave controller 210 is selected as the synchronous mode (sync), after the motor 117 is driven (step 210), It is determined whether an origin detection signal is input from the origin detection sensor 130 (step 220).

If it is determined in step 220 that the origin detection signal is input, the motor 117 is stopped (step 230).

Then, it is determined whether the motor driving resume signal is input through the second control signal line (step 240).

If it is determined that the motor driving resume signal is input in step 240, the motor 117 is driven (step 210).

Accordingly, the motor 117 of the color light generating unit 110 connected with the master controller 120 after a delay time set by the master controller 120 after the detection signal is input from the origin detection sensor 130 of the slave controller 210. ) And the motor 117 of the color light generating unit 110 connected to the slave controller 210 are started again at the same time, so that synchronization can be synchronized again every cycle.

An example of synchronous correction for each cycle by the color synchronous control process of the master luminaire 100 and the slave luminaire 200 is shown in FIG. 11. In the drawing, reference numeral Td denotes a set delay time, Ms denotes an output signal of the origin detection sensor 130 of the master lighting apparatus 100, Mm denotes an operation state of the motor 117 of the master lighting apparatus 100, and Ss1. Is the output signal of the home detection sensor 130 of the first slave lighting device 200, Ms1 represents the operating state of the motor 117 of the first slave lighting device 200, Ssn is the n-th slave lighting device ( The output signal of the origin detection sensor 130 of 200, Msn represents the driving state of the motor 117 of the n-th slave lighting device (200).

As can be seen from FIG. 11, even when the home detection time of the home detection sensor 130 is changed by the variation in the rotation speed of each of the motors 117 of the color light generating units 110, the home point connected to the master controller 120. If the detection signal is generated within the delay time obtained from the origin detection sensor 130 of the color light generation unit 110 connected to the slave controller 210 after the detection signal of the detection sensor 130 is generated, color synchronization is repeated every cycle. Can match.

As described so far, according to the color synchronization system and method of the multi-luminaire according to the present invention, a group of slave illuminators connected to the master luminaire every cycle of the synchronization adjustment of the rotational speed deviation of the color filter wheel with each other It provides an advantage that can be adjusted from time to time.
