Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical detection controlled device which automatically detects light emitted from a transmitter and drives it to swing, and more specifically, it is used in various studios, theaters, halls and the like. The present invention relates to improvement of controllability of remote drive control by an optical transmitter such as a remote control type spotlight and its verification system.

2. Description of the Related Art The inventors of the present application filed Japanese Patent Application No. 6-3173.
In 88, a structure of a spotlight whose irradiation direction can be controlled by remote control using a transmitter and various methods for driving and controlling the spotlight are proposed. Figure 1 shows the appearance of such a spotlight 1 '.
0 is shown. In this spotlight 1 ', five infrared ray receiving elements are provided on the front surface together with the light projecting lens 10,
The infrared light from the transmitter RC is detected, and the spotlight is driven toward the transmitter RC. This spotlight 1 '
The driving can be performed by a pan operation driven around the pan axis PJ and a tilt operation driven around the tilt axis CJ, and the pan operation or the tilt operation is performed based on the detection result of each infrared light receiving element. To do.

That is, of the infrared light receiving elements, the two infrared light receiving elements arranged in the horizontal direction are the pan light receiving elements PS1 and PS2, and the spotlight performs the pan operation based on the detection results of these light receiving elements. To do. On the other hand, the two infrared light receiving elements arranged in the vertical direction are the tilt light receiving elements CS1 and CS2, and the spotlight performs the tilt operation based on the detection results of these light receiving elements. Further, the infrared light receiving element arranged in the center is the drive stop light receiving element SS, and stops the pan operation and the tilt operation of the spotlight 1 ′ based on the detection result of this light receiving element. In this way, the spotlight 1 ′ can be driven and controlled by remote control so that the irradiation light of the spotlight can be emitted to an arbitrary position.

FIG. 11 shows a state of a detection area formed in front of a spotlight by the infrared light receiving element. PA1 and PA2 in the figure are pan light receiving elements P, respectively.
S1 and PS2 are detection areas, CA1 and CA2 are detection areas of the tilt light receiving elements CS1 and CS2, respectively, and SA is a detection area of the drive stopping light receiving element SS.

Furthermore, the inventors of the present application have proposed the following spotlight drive control method as a method for setting the irradiation direction of the spotlight 1'with high accuracy in the above-mentioned application. This drive control method will be described below. An example of a drive control method for a spotlight is shown in FIG.
This will be described with reference to FIGS. 13 and 14. The arrow in the figure indicates the position of the remote controller. First, when the spotlight is driven as shown in FIG. 12, the position where the remote controller enters the detection area SA is set to the position A. After that, the position exiting from the detection area SA is defined as position B, and positions A and B
The midpoint C is obtained, and the spotlight is driven in a direction 90 ° from the midpoint C to the driving direction up to now. This state is shown in FIG. Next, the position where the remote controller moves out of the detection area SA is designated as position D, and the position where the remote controller exits the detection area SA when driven in the opposite direction is designated as position E.
By finding the midpoint F of E and E and driving the spotlight to this midpoint F, the irradiation direction of the spotlight can be set to the direction of the remote controller with high accuracy. This is shown in FIG.

Another example of a spotlight drive control method will be described with reference to FIGS. Similar to the above example, the arrow in the figure indicates the position of the remote controller. First, FIG.
After the remote control enters the detection area SA, the detection areas PA1 and PA2 of the two pan light receiving elements PS1 and PS2 are detected.
The position within the overlapping range (overlap detection area) is position A, the pan operation only is performed from position A, and the position out of the overlap detection area is position B. The midpoint C between positions A and B Then, the spotlight is driven only by a tilt operation in a direction 90 ° from the driving direction from the midpoint C to the previous driving direction, that is, the tilt light receiving elements CS1 and CS2.
The position C that enters the overlap detection area and the position E that exits this overlap detection area are determined, and the midpoint F of the positions D and E is obtained.
When the spotlight is driven to the midpoint F, the irradiation direction of the spotlight can be set to the direction of the remote controller with high accuracy.

In order to perform highly accurate drive control by such a method, the shape of each detection area shown in FIG. 11 and the positional relationship between them are important. That is, the drive stop detection area SA and other detection areas PS1, PS2,
The parts of CS1 and CS2 in the detection area SA are
It is necessary that the circle or arc be as close to a perfect circle as possible, and that the detection area SA for stop be also of an appropriate size. Further, in the latter drive control method, it is also necessary that the respective detection areas are arranged in such a positional relationship that they have appropriate overlapping portions with each other.

In order to realize such a detection area, a spotlight provided with a guide tube was proposed in the previous application. The appearance of this spotlight 1 ″ is shown in FIG. In this spotlight 1 '', a guide tube P is provided in front of each light receiving element, and the guide tube P limits the infrared rays incident on each light receiving element to set the detection area of each light receiving element to a predetermined shape and shape. Since the size can be set, the irradiation direction of the spotlight 1 ″ can be set with high accuracy by remote control.

[0009]

However, the conventional spotlight has the following problems when the irradiation position is set by remote control using a transmitter. The first problem is that some variation in the length of the guide tube is inevitable in the production process of the spotlight, but since the conventional guide tube has a fixed length, there is an error in the production process. Could not be compensated. Such an error in the length of the guide cylinder causes an error in the size of each detection area, and the size of each detection area, particularly the detection area of the drive stop light-receiving element may not be an appropriate size. Further, the size of each detection area may change, so that each detection area may not have an appropriate overlapping portion with each other. For this reason, there is a problem in that the setting accuracy of the irradiation direction of the spotlights varies from one spotlight to another and the accuracy of drive control by the remote controller of the spotlights decreases.

As a second problem, when the directions in which the two light receiving elements for pan are arranged do not match the driving directions by the pan operation, or the directions in which the two light receiving elements for tilt are arranged are tilted. In the case where the drive direction due to the operation does not match, in the latter drive control method described above,
Although the setting accuracy of the irradiation position of the spotlight is lowered, the arrangement of each light receiving element is fixed, and the above-mentioned mismatch cannot be compensated. Such a disagreement between the arrangement direction of the light receiving elements and the driving direction may be caused by the variation in the production process similarly to the above, and the light receiving element is not provided in the spotlight body, and the five light receiving elements are not provided. In the case of a spotlight in which the light receiving element unit in which the is arranged is externally attached, the mounting error or the like also causes the problem. In particular, in the latter drive control method described above, since the irradiation position is determined by performing single-axis driving, if a deviation occurs between the arrangement direction of the light receiving elements and the single-axis driving direction, the spotlight Irradiation position setting accuracy decreases.

A third problem is that when the spotlight is driven by remote control, there is no system for displaying the driving status, and the progress of the driving can be confirmed and the accuracy of the irradiation position of the spotlight can be verified. Moreover, since the size of the detection area and the mutual relationship between the detection areas as shown in FIG. 11 cannot be directly known, conventionally, the confirmation work depends on the sense of the operator. However, quantitative verification was not possible.

The present invention has been made in view of the above circumstances, and when the spotlight detection area is not appropriate due to variations in the production process and the like, by adjusting these, the irradiation direction setting accuracy by remote control is adjusted. It is a first object to provide a spotlight that can improve the brightness. A second object of the present invention is to provide a spotlight irradiation direction verification system capable of confirming the driving condition of the spotlight and quantitatively verifying the setting accuracy of the irradiation direction and facilitating the adjustment work. And

Further, there is provided a spotlight detection area display system capable of facilitating the above-mentioned adjustment work by visually displaying the size of the detection area of each light receiving element and the mutual positional relationship thereof. This is the third purpose.
