Description

一种舞台灯光学元件驱动系统Stage light optical component drive system
技术领域Technical field

背景技术Background technique
在舞台灯光领域中,为了实现多种绚丽的舞台灯光效果,通常会在舞台灯具内部设置棱镜、色片、图案片等结构,通过棱镜、色片、图案片的结合使用可实现绚丽的光线效果。而单个棱镜使用时,打出的灯光效果局限性较大,效果比较单一,为了解决这个问题,在实际使用时,通常采用两个棱镜结合使用。如公开号为CN203868942U的中国实用新型专利,公开了一种用于舞台灯具的双棱镜组合,该双棱镜组合为1个8棱镜和1个多棱镜,所述的8棱镜和多棱镜在舞台灯具内均位于光源和通光孔上方,处于舞台灯具灯体头部内。现有技术通常都是采用这种双棱镜的结构来实现多棱镜的复合效果,各棱镜虽然均可在光轴平面内摆动,移入或移出光路,但在现有技术中,每个棱镜都是独立使用一套将其移入或移出光路的驱动机构,且各组棱镜的运动轴相互独立,不能共用,这使得现有技术存在以下缺陷:灯具内部必须分别为两组棱镜及其驱动机构各预留一定的安装位置及空间,这在空间设计上增加了设计难度,需要对各零部件进行严谨的空间设计,否则容易存在干涉现象,从而导致各零部件之间的使用相互受影响;而且需要配备多个电机及相应的驱动安装结构,在一定程度上大大增加了舞台灯具的制造成本,而且安装复杂。In the field of stage lighting, in order to achieve a variety of beautiful stage lighting effects, prisms, color patches, and pattern sheets are usually arranged inside the stage lamps, and a combination of prisms, color chips, and pattern sheets can achieve brilliant light effects. . When a single prism is used, the effect of the lighting is limited, and the effect is relatively simple. In order to solve this problem, in actual use, two prisms are usually used in combination. For example, a Chinese utility model patent published as CN203868942U discloses a double prism combination for a stage luminaire, which is a combination of an 8 prism and a multi-prism, and the 8 prism and the polygon mirror are in the stage luminaire. Located above the light source and the light-passing hole, in the head of the stage lamp body. In the prior art, the structure of the double prism is usually used to realize the composite effect of the multi-prism. Although each prism can swing in the plane of the optical axis and move in or out of the optical path, in the prior art, each prism is independent. A set of driving mechanism for moving it into or out of the optical path is used, and the moving axes of the prisms of each group are independent of each other and cannot be shared, which causes the prior art to have the following defects: the inside of the lamp must be separately reserved for the two sets of prisms and their driving mechanisms. A certain installation position and space, which increases the design difficulty in the space design, requires a rigorous space design for each component, otherwise it is prone to interference, which leads to the mutual use of each component; A plurality of motors and corresponding drive mounting structures greatly increase the manufacturing cost of the stage lamps to a certain extent, and the installation is complicated.

本实施例中,所述舞台灯光学元件驱动系统还包括驱动所述可转动光学元件自转的自转驱动机构。所述自转驱动机构包括自转驱动电机6(图中未示出)、主动轮10以及数量与可转动光学元件的数量相对应的从动轮11;自转驱动电机6与旋转主轴4一端连接,主动轮10固定连接在旋转主轴4上,各从动轮11均设在对应的光学元件支架3上,所述主动轮10、从动轮11和转盘12外周的齿轮结构13依次啮合连接。就本实施例而言,设置两个从动轮11分别驱动两个光学元件自转,所述主动轮10分别与两个从动轮11啮合。In this embodiment, the stage light optical component driving system further includes an rotation driving mechanism that drives the rotation of the rotatable optical component. The rotation driving mechanism includes a rotation driving motor 6 (not shown), a driving wheel 10, and a number of driven wheels 11 corresponding to the number of rotatable optical elements; the rotation driving motor 6 is connected to one end of the rotating spindle 4, and the driving wheel 10 is fixedly connected to the rotating main shaft 4, and each of the driven wheels 11 is disposed on the corresponding optical component holder 3. The driving wheel 10, the driven wheel 11 and the gear structure 13 on the outer circumference of the turntable 12 are sequentially meshed and connected. For the present embodiment, two driven wheels 11 are provided to drive the two optical elements to rotate, respectively, and the driving wheels 10 are respectively engaged with the two driven wheels 11.
本方案中,个光学元件支架3的初始位置均处于通光孔的外侧,此时各光学元件都不对舞台灯具发出的光束进行处理;当驱动电机6带动驱动齿轮5转动时,由于驱动齿轮5与其对应的光学元件支架3上的齿状结构8啮合连接,所以驱动齿轮5会带动与其对应的光学元件支架3进行旋转摆动,从而使光学元件2即棱镜移动到通光孔正上方位置对光束进行处理,同时,设于光学元件支架3上的从动轮11移动到与主动轮10相啮合的位置进行啮合连接;此时,打开自转驱动电机6,自转驱动电机6将带动固定连接在旋转主轴4上的主动轮10转动,主动轮10通过啮合作用带动从动轮11转动,从动轮11通过啮合作用带动转盘12转动,进而实现光学元件2即棱镜的自转运动。当不需要棱镜对光束进行处理时,改变驱动电机6的旋转方向,即可以将光学元件2即棱镜移出通光孔正上方位置,由于支撑板的相应位置上设置有限位柱7,因此光学元件2即棱镜的运动不会超程。In this solution, the initial positions of the optical component holders 3 are all outside the light-passing holes, and at this time, the optical components of the stage lamps are not processed by the optical components; when the driving motor 6 drives the driving gears 5 to rotate, the driving gears 5 The toothed structure 8 on the optical component holder 3 is meshed with the corresponding optical component holder 3, so that the driving gear 5 drives the optical component holder 3 corresponding thereto to perform a rotational swing, thereby moving the optical component 2, that is, the prism, to the position directly above the light passing hole. At the same time, the driven wheel 11 provided on the optical component holder 3 is moved to a position engaged with the driving wheel 10 for meshing connection; at this time, the rotation driving motor 6 is turned on, and the rotation driving motor 6 is fixedly connected to the rotating spindle. The driving wheel 10 on the 4 rotates, the driving wheel 10 drives the driven wheel 11 to rotate by the meshing action, and the driven wheel 11 drives the turntable 12 to rotate by the meshing action, thereby realizing the rotation movement of the optical element 2, that is, the prism. When the prism is not required to process the beam, the rotation direction of the driving motor 6 is changed, that is, the optical element 2, that is, the prism, can be moved out of the position directly above the light passing hole, and the finite column 7 is disposed at the corresponding position of the supporting plate, so the optical element 2 The movement of the prism does not overtravel.
本方案中,通过各驱动机构及自转机构的控制运动,可使得两个棱镜同时移入光路中,对光束进行分光处理,实现双棱镜的复合光束效果,且双棱镜同时自转,还可实现光斑旋转效果;另外,各棱镜也可以不同时处于光路中,只有一个棱镜置于光路中或两个棱镜均置于光路外。In this solution, by controlling the movement of each driving mechanism and the rotation mechanism, the two prisms can be simultaneously moved into the optical path, and the beam is split-processed to realize the composite beam effect of the double prism, and the double prism simultaneously rotates, and the spot rotation can be realized. In addition, each prism may also be in the optical path at the same time, only one prism is placed in the optical path or both prisms are placed outside the optical path.
