【Example】

 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 the case of this embodiment, the irradiation direction of the spotlight SL is automatically set in addition to the selecting unit 1 and the operating unit 2 described in FIG. An automatic operation unit 3 and a mode switch 7 for setting the operation device to a setting mode in which each switch 3a of the automatic operation unit 3 and the irradiation direction of the spotlight SL are associated with each other are provided.

For example, when the automatic operation unit 3 illuminates the stage ST as a surface to be illuminated shown in FIG. 3, the matrix is imitated by dividing the stage ST into a plurality of areas indicated by broken lines in the figure. A plurality of switches 3a arranged in a circle are provided. Here, as described above, if the illuminated surface such as the stage ST to be illuminated is determined and the mounting position of the spotlight SL is known in advance, the PAN angle of the spotlight SL when each switch 3a is pressed. And the TILT angle are uniquely determined. Therefore, the PAN angle and TILT angle corresponding to each switch 3a of each spotlight SL are stored in the operating device SD as shown in FIG. 4 (b), so that the switch 3a of the automatic operating unit 3 is operated. The irradiation direction of each spotlight SL can be automatically changed. The numbers in circles in FIG. 4 (b) indicate the numbers of the switch 3a, the first data in the parentheses is the PAN angle data, and the subsequent data is the TILT angle data.

FIG. 1 specifically shows an example of a circuit configuration. The operation device SD is equipped with a control unit 10 composed of a microcomputer, and the automatic operation unit 3 of each spotlight SL is installed. The PAN angle and TILT angle data corresponding to each switch 3a is stored in the storage unit (ROM) 12, the operation status of the switch 3a of the automatic operation unit 3 is fetched through the input unit 13, and the calculation unit 11 including a CPU is used. The corresponding PAN angle and TILT angle data is read out and the 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 given to the motors 5a and 5b via the error amplification circuits 4a and 4b. Here, in the error amplifier circuits 4a and 4b, an output according to the irradiation direction of the spotlight SL detected by the potentiometers 6a and 6b and a PAN angle adjustment output and a TILT angle adjustment output provided from the micro computer are provided. The outputs are compared and an output corresponding to the difference is given to the motors 5a and 5b. That is, the motors 5a and 5b are provided with outputs according to the difference between the actual PAN angle and TILT angle of the spotlight SL and the PAN angle and TILT angle to be set, and the PAN angle and 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. 6 (a) (in FIG. 6 (a), the shaded switch 3a is pressed). As shown in b), the irradiation direction of the spotlight SL is automatically changed so that the spotlight SL illuminates a desired area of the stage ST as a surface to be illuminated corresponding to the switch 3a. If fine adjustment is necessary, the irradiation direction may be adjusted using the PAN switches 2a and 2b and the TILT switches 2c and 2d of the manual operation unit 2.

By the way, each switch 3a of the automatic operation section 3 is provided with a light emitting section which emits light at the time of operation, and as shown in FIG. 7A, the PAN switches 2a and 2b and the TILT switch of the manual operation section 2 are provided. As shown in FIG. 7 (b), the light emitting unit of the automatic operation unit 3 shows which part of the stage, which is the irradiated surface, is illuminated when the spotlight SL is manually operated in the irradiation direction by the 2c and 2d. Is made to clearly indicate by emitting light (in FIG. 7 (b), the light emitting state of the light emitting portion is shown by diagonal lines). As such a switch 3a, for example, a switch integrally incorporating a light emitting diode may be used.

In this case, which area the light emitting diode corresponding to which light is to be emitted according to the operation of the manual operation unit 2 will be described below. In the operating device SD, since the PAN angle and TILT angle data at the center of the area on the stage are known, the boundary value between areas can be obtained in advance. For example, the boundary line of the switch 3a indicated by the circled numbers 7 and 2 of the automatic operation unit 3 in FIG. 4B is the center of the circled numbers 1 and 2 and the circled numbers 19 and 20. It can be obtained as a straight line passing through points. Similarly, if other boundary lines are obtained, the arithmetic unit 11 can determine which area the irradiation position is located, and the light emitting diode of the corresponding switch 3a can be caused to emit light in accordance with 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 of A and E and the center (B + F) / 2 of B and F shown in FIG. 8 is obtained. Letting the straight line L be ax + by + c, the coefficients a to c are: 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 ) / 2. Therefore, it is possible to find each boundary line in this manner and to find out which of the above-mentioned switch 3a the area belongs to.

In addition, when it comes off from the irradiated surface corresponding to the automatic operation unit 3, the outside-area display device 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. Also, since there are no special operations such as ten-key operations, even an unskilled person can easily perform the operation. Further, since the irradiation position is monitored by the light emitting diodes arranged in a matrix, there is an advantage that it is cheaper than the case where a display such as a CRT or a liquid crystal is used. Moreover, in this type of display, the spotlight SL is displayed at a rotation angle from the origin (for example, + 90 °), so 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 and the actual irradiation position of the spotlight SL shown in FIG. The irradiation position can be recognized.

By the way, the above description has been the description of the remote control spotlight system which is the basis of the present invention, but the characteristic points of the present invention will be described below. In this embodiment, the operation mode of the operating device SD is set to the setting mode by switching the mode switch 7, and each switch 3a of the automatic operation unit 3 and the irradiation direction of the spotlight SL are associated with each other.

In this association, the spotlight SL is selected by the selection unit 1, and the desired irradiation position is selected by the PAN switches 2a and 2b and the TILT switches 2c and 2b of the manual operation unit 2 as shown in FIG. 9A. Illuminate with a spotlight SL. Then, as shown in FIG. 9B, the switch 3a of the automatic operation section 3 corresponding to the irradiation position is pushed. The computing unit 11 stores the PAN angle and TILT angle data at this time in the RAM of the storage unit 12.

This operation is repeated any number of times. In this case, repeat the above operation 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 places (for example, A to D in FIG. 9) as far as possible. In the case of two locations, the diagonal locations (A and D in FIG. 9, or B and C) may be used.

After the initial setting, the other switches 3a and the irradiation positions are associated with each other by the equal interval approximation based on the PAN angle and TILT angle data corresponding to each of the above-mentioned captured positions. This processing is performed by the arithmetic unit 11. For example, suppose that the initial setting is performed at the four corners A to D of the irradiated portion in FIG. 4A and the number of switches 3 a in the row of the automatic operation unit 3 is M. The PAN angle data x _1t and the TILT angle data y _1t of each switch 3a in between are x _1t = | x ₁₁ + t (x _1M −x ₁₁ ) / (M−1) | y _1t = | y ₁₁ + t ( y _1M −y ₁₁ ) / (M−1) | However, the PAN angle data and TILT angle data at the point A are (x ₁₁ , y ₁₁ ), and the PAN angle data and the TILT angle data at the point B are (x _1M , y _1M ), and t = 2, ..., (M -1).

Similarly, PAN angle data and TILT angle data of each switch 3a between A and C, between C and D, and between B and D are obtained, and by using those data, the switch 3a between them is detected. PAN angle data and TILT angle data are obtained. In this way, even when the construction site, the spotlight SL installation location, and the spotlight SL installation direction are changed, the correspondence between each switch 3a of the automatic operation unit 3 and the irradiation direction of the spotlight SL. Attachment can be done arbitrarily and easily.
