The present invention relates to a remote control spotlight system that can be used.

[0002]

2. Description of the Related Art As a remote control spotlight system, as shown in FIG. 10, there is a system in which the irradiation direction of a plurality of spotlights SL can be adjusted by an operation using an operation device SD. Here, in the case of the remote control spotlight system, the actual irradiation direction of the spotlight SL is adjusted by the control device CD, and the operation device SD gives the control device CD a command to change the irradiation direction. . From the operation device SD, a command to change the irradiation direction of the spotlight SL in the horizontal plane (hereinafter, referred to as PAN), and to change the irradiation direction in the vertical plane (hereinafter, referred to as PAN).
Command to perform TILT (tilt), and PAN, TILT
Data such as a rotation angle at the time of operation is serially transmitted to the control device CD. The PAN and TILT adjustment is performed by operating a joystick, a trackball, a push button, or the like provided on the operation device SD.

[0003] PAN, TIL is provided on the spotlight SL side.
A motor for each adjustment of T is provided and the control device CD
Is designed so that the irradiation direction of the spotlight SL can be changed by controlling the driving of each motor. However, in the case of this remote control spotlight system, the irradiation direction of the spotlight SL is variably controlled through the control device CD. However, the function of the control device CD is incorporated in the operation device SD, and the operation device SD is used. In some cases, the irradiation direction of the spotlight SL is directly changed.

FIG. 11 shows an example of the operating device SD.
In the operation device SD, the selection unit 1 including a plurality of switches for individually selecting the spotlights SL, and the adjustment of the irradiation direction of the spotlight SL selected by the selection unit 1, that is, the adjustment of PAN and TILT, are manually performed. And a manual operation unit 2 for performing the operation. In the operation device SD, the spotlight SL to be operated is selected by the selection unit 1, the horizontal rotation is operated by a pair of left and right PAN switches 2a and 2b, and the vertical rotation is controlled by a pair of upper and lower TILT switches 2
By operating with c and 2d, the irradiation direction of the spotlight SL is changed. The irradiation direction of all spotlights SL can be changed in this way.

When the irradiation direction is set as described above, the setting data of the plurality of spotlights SL is stored as scene or pattern data in the other operating device SD, and the numeric keypad operation or exclusive operation is performed. In some cases, the adjustment state of the irradiation direction of the plurality of spotlights SL can be reproduced by operating a switch. Also, on a display such as a CRT or liquid crystal display,
There is also a spotlight SL in which a PAN and a TILT angle are numerically displayed and monitored.

[0006]

However, when the spotlight SL is remotely operated as described above, the movement of the spotlight SL may not coincide with the directions of the PAN and TILT switches 2a to 2d depending on the mounting direction. In some cases, the movement of the light emitted from the light SL does not match the operational feeling. For this reason, there is a problem that the operation of changing the irradiation direction of the spotlight SL requires skill.

In view of this, an automatic operation unit composed of a plurality of switches integrally including a light emitting unit arranged in a matrix to simulate a state in which a surface to be irradiated is divided into a plurality of areas, and each switch of the automatic operation unit A storage unit for storing the irradiation direction of each spotlight for each area of the corresponding irradiated surface, and a storage unit for storing setting data according to the selection of the spotlight by the selection unit and the selection of the irradiation position by a switch operation of the automatic operation unit. A control means for automatically changing the irradiation direction of the spotlight by reading from the control unit and giving it to the irradiation direction adjustment means is provided in the operation unit, and a matrix simulating a state in which the irradiation surface of the automatic operation unit is divided into a plurality of areas. It is possible to change the irradiation position of the spotlight by operating the switches arranged in a shape so that it is possible to recognize to some extent the irradiation position And, there is a remote control spotlight system facilitates the setting of the irradiation direction of the spotlight.

[0008] However, in this remote control spotlight system, it is necessary as a precondition that the installation location of the spotlight SL and the direction of the origin of the PAN and TILT control of the spotlight SL are predetermined.
In other words, without the above prerequisites, it is not possible to previously store the PAN angle and TILT angle data corresponding to the switch in the memory.

However, there are few cases where the installation location of the spotlight SL and the origin direction of the PAN and TILT control of the spotlight SL are not changed in the future, and when the change is made, a memory for storing the irradiation direction data corresponding to the switch of the automatic operation unit is provided. This type of remote control spotlight system requires that the memory be replaced at each location where it is installed. However, replacing the memory in this manner is not versatile.

[0010] The present invention has been made in view of the above points, and an object of the present invention is to provide a remote control spotlight system which can easily adjust the irradiation direction without requiring any skill, and which has an automatic operation unit. An object of the present invention is to make it possible to easily change irradiation direction data corresponding to a switch.

[0011]

According to the present invention, in order to achieve the above object, a plurality of spotlights, irradiation direction adjusting means such as a motor for individually changing the irradiation direction of the spotlight, and irradiation direction adjusting means are provided. A selection unit for individually selecting each spotlight, a manual operation unit for manually changing the irradiation direction of the spotlight selected by the selection unit,

And a control means for determining the irradiation position by manual operation from the light source to emit light from the light emitting unit of the automatic operation unit. In the spotlight system,

A predetermined area at a location or more is illuminated, and at that time, a switch corresponding to the predetermined area of the automatic operation unit is turned on to input data of a spotlight irradiation direction in the predetermined area. The irradiation direction of the spotlight corresponding to each area of the irradiated surface is calculated and stored in the storage unit.

[0012]

According to the present invention, a mode switch for setting a setting mode for associating each switch of the automatic operation unit with the irradiation direction of the spotlight is provided in the operation device as described above, and the manual operation unit is used in the setting mode.

1 to 9 show an embodiment of the present invention. FIG. 2 shows the appearance of the operating device SD of the present invention. In this embodiment, in addition to the selecting unit 1 and the operating unit 2 described in FIG. 10, the setting of the irradiation direction of the spotlight SL is automatically performed. An automatic operation unit 3 and a mode switch 7 for setting the operation device to a setting mode for associating each switch 3a of the automatic operation unit 3 with the irradiation direction of the spotlight SL are provided.

If the automatic operation unit 3 illuminates the stage ST as a surface to be illuminated as shown in FIG. 3, for example, the matrix ST simulates a state where the stage ST is divided into a plurality of areas indicated by broken lines in the figure. A plurality of switches 3a arranged in a circle. Here, as described above, the surface to be illuminated such as the stage ST to be illuminated is determined, and if the mounting position of the spotlight SL is known in advance, each switch 3a
PAN angle and TI of spotlight SL when is pressed
The LT angle is uniquely determined. Therefore, each spotlight S
PAN angle and TIL corresponding to each switch 3a of L
By storing the T angle in the operating device SD as shown in FIG. 4B, the irradiation direction of each spotlight SL can be automatically changed by operating the switch 3a of the automatic operation unit 3. The numbers in circles in FIG. 4B indicate the numbers of the switches 3a, and the first data in parentheses is PAN.
The angle data and the subsequent data indicate TILT angle data.

FIG. 1 specifically shows an example of the circuit configuration. A control unit 10 comprising a microcomputer is mounted on an operating device SD, and each spotlight SL is provided.
The PAN angle and TILT angle data corresponding to each switch 3a of the automatic operation unit 3 are stored in the storage unit (ROM) 12, and the operation status of the switch 3a of the automatic operation unit 3 is fetched through the input unit 13, The corresponding PAN angle and TILT angle data are read by the arithmetic unit 11 composed of a CPU, and control signals corresponding to the PAN angle and TILT angle data are output from the output units 14a and 14b.

Control signals from the output units 14a and 14b are supplied to the motors 5a and 5b via error amplifier circuits 4a and 4b. Here, the error amplifier circuits 4a and 4b compare the output corresponding to the irradiation direction of the spotlight SL detected by the potentiometers 6a and 6b with the PAN angle adjustment output and the TILT angle adjustment output given from the microcomputer. An output corresponding to the difference is given to the motors 5a and 5b. That is, an output corresponding to the difference between the actual PAN angle and the TILT angle of the spotlight SL and the set PAN angle and the TILT angle is given to the motors 5a and 5b, and the PAN angle and the TILT angle of the spotlight SL are set to the desired PAN angle. Angle and TILT angle.

In this way, the irradiation direction of the spotlight SL can be roughly adjusted by operating one switch 3a of the automatic operation unit 3. That is, when one of the switches 3a of the automatic operation unit 3 is pressed as shown in FIG.
(A) shows a state in which the switch 3a with diagonal lines is pressed), and a spotlight SL illuminates a desired area of the stage ST as a surface to be irradiated corresponding to the switch 3a as shown in FIG. As a result, the irradiation direction of the spotlight SL is automatically changed. When fine adjustment is necessary, the PAN switches 2a and 2b of the manual operation unit 2 are used.
Then, the irradiation direction may be adjusted using the TILT switches 2c and 2d.

By the way, each switch 3a of the automatic operation unit 3 is integrally provided with a light emitting unit which emits light when operated, and as shown in FIG.
7A and 7B, when the irradiation direction of the spotlight SL is manually operated by the TILT switches 2c and 2d, which part on the stage which is the irradiated surface is illuminated.
As shown in FIG. 7B, the light emitting unit of the automatic operation unit 3 emits light so that the light emitting unit is clearly shown (in FIG. 7B, the light emitting state of the light emitting unit is indicated by oblique lines). As such a switch 3a, for example, a switch having a built-in light emitting diode may be used.

In this case, a description will be given below of which area the light emitting diode corresponding to which is operated in response to the operation of the manual operation unit 2 emits light. Since the operating device SD knows the PAN angle and TILT angle data at the center of the area on the stage, the boundary value between the areas can be obtained in advance. For example, a switch 3 indicated by numerals 7 and 2 in a circle of the automatic operation unit 3 in FIG.
The boundary line a can be determined as a straight line passing through the center point of the encircled numerals 1 and 2 and the encircled numerals 19 and 20. Similarly, if another boundary line is also obtained, the calculation unit 11 can determine which area the irradiation position comes to, and the corresponding light emitting diode of the switch 3a can emit light according to the determination result.

Here, the method of determining the irradiation position in the manual operation unit 2 will be described in further detail with reference to FIG. For example,
A straight line L passing through the center (A + E) / 2 between A and E and the center (B + F) / 2 between B and F shown in FIG. 8 is obtained. Let the straight line L be a
When x + by + c, the coefficient a~c _{is, a = (y 11 + y} 21) / 2- (y 1M + y 2M) / 2 b = (x 11 + x 21) / 2- (x 1M + x 2M) / 2 c _{= (x 11 + x 21)} / 2 · (y 1M + y 2M) / 2 - (x 1M + x 2M) / 2 · (y 11 + y 21) obtained simplicity as / 2. Therefore, each boundary line can be obtained in this way, and it can be determined which of the above-mentioned switches 3a belongs to the area.

In the case of departure from the surface to be illuminated corresponding to the automatic operation unit 3, the outside area indicator 3b provided outside the switch 3a of the automatic operation unit 3 is made to emit light as shown in FIG. is there. In this way, the irradiation direction can be adjusted without actually turning on the spotlight SL. Further, since there is no special operation such as ten key operation, the operation can be easily performed even by a non-expert. Further, since the irradiation position is monitored by the light emitting diodes arranged in a matrix, there is an advantage that the cost is lower than when a display such as a CRT or a liquid crystal is used. In addition, in this type of display, since the display is performed at the rotation angle (for example, + 90 °) from the origin of the spotlight SL, it is difficult to imagine the relationship with the actual irradiation position. On the other hand, in the present embodiment, the switch arrangement of the automatic device unit 3 shown in FIG. 5A is close to the actual irradiation position of the spotlight SL shown in FIG. We can recognize position.

By the way, the above explanation is about the remote control spotlight system which is the basis of the present invention.
The features of the present invention will be described below. In the present embodiment, the operation mode of the operating device SD is set to the setting mode by switching the mode switch 7 and
Is associated with the irradiation direction of the spotlight SL.

At the time of this association, the spotlight SL is selected by the selector 1 and the desired irradiation position is set by the PAN switches 2a and 2b and the TILT switches 2c and 2b of the manual operation unit 2 as shown in FIG. Spotlight SL
To illuminate. Then, as shown in FIG. 9B, the switch 3a of the automatic operation unit 3 corresponding to the irradiation position is pressed.
The PAN angle and TILT angle data at this time are calculated by the arithmetic unit 11
Is stored in the RAM of the storage unit 12.

This operation is repeated an arbitrary number of times. In this case, the above operation is repeated in at least two places. However, in order to improve the accuracy of associating the switch 3a with the construction site, it is preferable to repeat the above operation at four or more distant locations (for example, A to D in FIG. 9). In the case where the operation is performed at two locations, the operation may be performed at diagonal positions (A and D in FIG. 9 or B and C in FIG. 9).

After this initial setting, the other switches 3a and the irradiation positions are associated with each other by an equal interval approximation based on the PAN angle and the TILT angle data corresponding to each of the fetched positions. This processing is performed by the calculation unit 11. For example, suppose that the initial setting is performed at the four corners A to D of the irradiated portion in FIG.
Assuming that the number of “a” is M, the PAN angle data x _1t and the TILT angle data y of each switch 3a between AB.
_{1t is, x 1t = | x 11 +} t (x 1M -x 11) / (M-1) | y 1t = | y 11 + t (y 1M -y 11) / (M-1) | become. However, the PAN angle data and TILT angle data at point A are (x ₁₁ , y ₁₁ ), and the PAN angle data and TI
The LT angle data is (x _1M , y _1M ), and t = 2,.
(M-1).

Similarly, between A and C, between C and D, and between B and D
PAN angle data and TILT of each switch 3a in between
The angle data is obtained, and the PAN angle data and the TILT angle data of the switch 3a therebetween are obtained by using the data. In this way, even when the construction location, the mounting location of the spotlight SL, and the mounting direction of the spotlight SL are changed, the correspondence between each switch 3a of the automatic operation unit 3 and the irradiation direction of the spotlight SL. Can be arbitrarily and easily performed.
