Description

Technical Field

[0001] The utility model specifically relates to the technical field of waterproof par lights, and specifically is a waterproof par light for stage use. Background Technique

[0002] Stage par lights are a kind of lamps used for stage lighting. Usually, LEDs are used as light sources, which have the advantages of rich colors, high brightness, energy saving and power saving. It can be programmed through a console to realize the switching of various colors and effects, adding atmosphere and effects to stage performances;

[0003] Before the performance, professionals will program the stage par lights, and debug the required effects according to the pre-set light path and colors according to the principle of the three primary colors. During the actual performance, the colors and effects can be continuously changed at any time according to needs;

[0004] To solve the problem of the glare of stage par lights, designers usually cover a layer on the par lights to reduce the glare of the lights. At the same time, in order to make the actors be seen more clearly on the stage, separate special lamps are needed for supplementary lighting.

[0005] After retrieval, Chinese Patent Publication No. CN201821313140.4 discloses a multi-angle portable waterproof par light; including a par light and a telescopic rod. A sliding groove is opened on the front of the par light, and a sliding block is movably connected inside the sliding groove. A connecting groove is opened at one end of the telescopic rod. The sliding block is movably connected with the telescopic rod through the connecting groove. The front of the sliding block is movably connected with a first movable rod. A second connecting rod is fixedly connected to the front of the first movable rod. A rotary button is movably connected to the front of the second connecting rod. A rotary seat is fixedly connected to one end of the telescopic rod;

[0006] The waterproof par light in the above patent cannot effectively adjust the problem of glare when the light is used, and cannot flexibly control the lighting effect according to different scene requirements. When used on the stage, it cannot effectively achieve the stage effect to be expressed;

[0007] In view of the above situation, we provide a waterproof par light for stage use. In this device, the waterproof seal housing and the convex lens inside the cover housing are installed on the slip ring. One side of the slip ring is connected to the connecting rod through a ball head. In this way, when displaying the stage effect, the controller is used to drive the deflection plate to deflect effectively through the motor. During the deflection of the deflection plate, the connecting rod is driven to move back and forth through the fixed rod, so as to realize the adjustment of the distance between the convex lens on the slip ring and the LED lamp in the lamp cover. When the distance is close, the light spot is relatively small and concentrated; when the distance is far, the light spot will become larger and spread. When the distance is relatively close, the light intensity is usually higher; as the distance increases, the light intensity will weaken relatively. In this way, the divergence and concentration of the light can be effectively adjusted, and by changing the divergence angle of the light beam, the range covered by the light can be affected. Summary of the Invention

[0008] The purpose of the present utility model is to provide a waterproof par lamp for stage. Through the controller, the motor drives the deflection plate to deflect effectively.

[0029] On the side of the heat dissipation fins 10 away from the fixed disk 9, a controller 12 is fitted and installed; mounting housings 120 are symmetrically arranged on both sides of the controller 12, and a motor 121 is installed inside the mounting housing 120; the output shaft of the motor 121 is fixedly installed with a deflection plate 122; the top of the deflection plate 122 is connected with a fixed rod 123 in a matching manner; a connecting rod 124 is movably installed on the fixed rod 123.

[0030] Specifically, the connecting rod 124 passes through the double round head groove 90 opened on the fixed disk 9 and is connected with the slip ring 7 through a ball head; a convex mirror 6 is installed inside the slip ring 7;

[0031] By adopting the above technical solution, the cover 2 and the waterproof sealing shell 3 are hermetically connected, which can effectively ensure the waterproof performance of the par lamp. When in use, when the light needs to be adjusted, the motor 121 inside the mounting shell 120 is rotated through the controller 12, so that the deflecting plate 122 mounted on the output shaft of the motor 121 swings. During the swinging process of the deflecting plate 122, the fixed rod 123 effectively drives the connecting rod 124 to move back and forth. One end of the connecting rod 124 away from the fixed rod 123 is connected to the slip ring 7 through a ball head, so that the slip ring 7 slides back and forth in the chute inside the cover 2 through the protruding blocks 11 on both sides;

[0032] Furthermore, symmetric protruding blocks 11 are installed on the outer edge of the slip ring 7; the protruding blocks 11 are in sliding fit with the chute provided on the inner edge of the cover 2; the cover 2 is hermetically connected to the waterproof sealing shell 3;

[0033] When the slip ring 7 drives the convex lens 6 away from the lamp in the lamp housing 8, the light spot will become larger and spread, and the light intensity will relatively decrease. When the slip ring 7 drives the convex lens 6 closer to the lamp in the lamp housing 8, the light spot is relatively smaller and concentrated, and the light intensity is usually higher. Therefore, through this adjustment, the light effect can be flexibly controlled according to different scene requirements.

[0034] The outer edge of the waterproof sealing shell 3 is connected to the handle 4 through bolts, and the handle 4 is arranged in a C shape; the waterproof sealing shell 3 is also connected to the support frame 5; the waterproof sealing shell 3 and the support frame 5 are cooperated by two bolts, and one of the bolts is installed in the arc groove 51 opened on the support plate 50.

[0035] In this embodiment, the support frame 5 is arranged in a U shape and is connected to the base 1 through bolts at the bottom;

[0036] By adopting the above technical solution, the waterproof sealing shell 3 is adjusted in angle along the arc groove 51, so that when used on the stage, the lighting effects at different angles can be effectively satisfied.

[0037] The working principle of the present utility model is: the cover 2 and the waterproof sealing shell 3 are hermetically connected, which can effectively ensure the waterproof performance of the par lamp. When in use, when the light needs to be adjusted, the motor 121 inside the mounting shell 120 is rotated through the controller 12, so that the deflecting plate 122 mounted on the output shaft of the motor 121 swings. During the swinging process of the deflecting plate 122, the fixed rod 123 effectively drives the connecting rod 124 to move back and forth. One end of the connecting rod 124 away from the fixed rod 123 is connected to the slip ring 7 through a ball head, so that the slip ring 7 slides back and forth in the chute inside the cover 2 through the protruding blocks 11 on both sides;

[0038] When the slip ring 7 drives the convex lens 6 away from the lamp inside the lamp cover 8, the light spot will become larger and spread, and the light intensity will relatively decrease. When the slip ring 7 drives the convex lens 6 closer to the lamp inside the lamp cover 8, the light spot is relatively smaller and concentrated, and the light intensity is usually higher. Thus, through this adjustment, the lighting effect can be effectively and flexibly controlled according to different scenario requirements.
