Description

Technical Field

[0001] The utility model relates to the technical field of stage light testing, and more specifically to a stage light parameter detection system which is easy to adjust. Background Art

[0002] In order to present a visual feast, the stage needs a large number of stage lights with rich categories to work together. Especially in stage design, designers usually use a large number of wash lights for stage rendering, so the brightness and color temperature consistency of each lamp is very important. However, in the process of stage lamp assembly, deviations are prone to occur due to various reasons, which may cause differences in different positions of the light spot generated by the lamp. For this reason, the lamp needs to undergo strict light spot testing before leaving the factory to ensure its light spot uniformity.

[0003] When using a goniophotometer to detect the light spot of a lamp today, it is necessary to move the lamp to adjust the distance between it and the tester, and manually adjust the center of the light-emitting surface of the lamp to align with the center of the tester's probe at the initial position. Then, by rotating the light-emitting surface of the lamp, use the probe to measure the brightness and / or color temperature parameters of the light spot of the lamp at various positions horizontally or vertically to evaluate the uniformity of the light spot. However, during dynamic monitoring, since both the tester and the stage lamp are relatively heavy, it is not convenient to move one of them; even if a smaller probe is moved, it is difficult to adapt to the rapid monitoring of various types of lamps, and the operation process is complicated. Utility Model Content

[0004] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a stage lighting parameter detection system which is easy to adjust. By adding a lifting platform and a rotating device, the emission angle of the lamp can be conveniently adjusted when testing the uniformity of the light spot of the lamp.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: to provide a stage lighting parameter detection system that is easy to adjust, including a base, a rotating mechanism rotatably connected to the base, a lifting platform for placing lamps, a tester for receiving and detecting the light spot formed by the lamps, and a first driving mechanism and a second driving mechanism; the rotating mechanism is connected to the lifting platform, the second driving mechanism drives the rotating mechanism to rotate to drive the lamp on the lifting platform to rotate, so that the light spot generated by the lamp transversely scans the probe of the tester, and the first driving mechanism drives the lifting platform to rise and fall to change the height of the lamp, so that the center of the light emitting surface of the lamp is aligned with the center of the probe of the tester.

[0006] This detection system can fix the height and position of the tester probe, and can easily move the lamp only through the lifting platform and the rotating mechanism, so as to complete the determination of the initial position, and can adapt to different types of lamps, with strong adaptability and versatility. Specifically, during the detection process, the first driving mechanism is first used to drive the lifting platform to change the height of the light-emitting surface of the lamp to align it with the probe of the tester. Then, the second driving mechanism is used to drive the rotating mechanism to drive the lamp to rotate. In the light spot generated by the lamp, the parameters of multiple positions at the same height are respectively received and detected by the probe of the tester, and finally the uniformity and consistency of the detected light spot can be quickly determined.

[0007] Furthermore, the lifting platform includes at least one folding bracket formed by pivoting the middle of the first connecting rod and the second connecting rod, and a telescopic rod connected to the first driving mechanism for driving the folding bracket to be folded or unfolded. The telescopic rod transmits the driving force of the first driving mechanism to the folding bracket, so that the folding bracket changes state according to demand, thereby changing the height of the lamp, facilitating the alignment of the center of the light-emitting surface of the lamp with the center of the probe, and quickly determining the initial position. The folding bracket structure has the characteristics of a large lifting space, a simple structure, and a small space occupied when in the folded state.

[0008] Furthermore, the lifting platform further comprises a support for connecting the rotating mechanism, two folding brackets arranged opposite to each other and a crossbar connecting the two folding brackets, one end of the telescopic rod is rotatably connected to the crossbar, and the other end is rotatably connected to the support. The structure is stable and the lifting process is more stable.

[0009] Furthermore, it also includes a third driving mechanism for fine-tuning the height of the lifting platform, thereby further improving the adjustment accuracy of the lifting platform.

[0010] Furthermore, the first driving mechanism is a pneumatic pump body or a hydraulic pump body. The pneumatic pump body has high safety, reliability and durability, and the output pressure and flow are easy to adjust, and the operation and maintenance are simple; while the hydraulic pump body is suitable for use scenarios that require high efficiency, precise control and smooth output, and the designer can choose according to needs.

[0011] Furthermore, the lifting platform also includes a base plate for mounting the lamp, and the base plate is provided with a plurality of lock holes for locking the lamp, so that the lamp is firmly mounted on the base plate, and the lamp will not produce displacement deviation due to inertia during the lifting process or the rotational movement, thereby ensuring the accuracy of the detection data.

[0012] Furthermore, the rotating mechanism comprises a circular turntable connected to the lifting platform, the turntable is provided with a scale for recording its own rotation angle, and the base is provided with a guide line corresponding to the scale. When the lamp is performing a horizontal sweep of the probe, the angle of rotation can be clearly observed and recorded.

[0013] Furthermore, it also includes a positioning mechanism that connects and drives the rotating mechanism and / or the lifting platform to move closer to or away from the center of the tester probe, providing the lamp with an additional displacement direction, and easily fine-tuning the distance between the lamp and the tester probe, so that the initial test position can be confirmed more quickly.

[0014] Furthermore, the outer surfaces of the lifting platform and / or the rotating mechanism and / or the tester are subjected to anti-reflection treatment, so as to reduce the interference caused by the reflection of ambient light or other light, reduce the influence of stray light entering the probe on the experimental data, and improve the detection accuracy.

[0015] Furthermore, the distance between the tester and the light-emitting surface of the lamp is at least 15 meters, so as to avoid the situation that when the lamp is a laser lamp or other high-power lamp, too much concentrated light enters the tester at the same time, causing inaccurate test results or even damage.

[0016] Furthermore, at least one shading plate is provided between the tester and the lamp, and the shading plate has a light hole for the light beam emitted by the lamp to pass through and project toward the tester. The shading plate can assist the light spot generated by the lamp to align with the probe of the tester.

[0017] Furthermore, it also includes a laser level for assisting in calibrating the center position of the light emitting surface of the lamp, so as to further accurately locate the installation or placement position of the lamp and ensure the accuracy of the detection data.
