Abstract

The utility model relates to a light spot cutting imaging system for a stage illumination lamp, which comprises a plurality of metal light cutting slices which are not contacted with each other, an extensible grating, a plurality of motors for driving the light cutting slices or the grating to move through a gear. The motors drive the light cutting slices to move in a matching mode through the gear so as to achieve light through ports in any shape and at any direction, light beams project out through the light through ports to form corresponding light spot patterns, and a light spot can be adjusted through contraction of the grating. The light spot cutting imaging system solves the problem that an original stage illumination lamp cannot cut the light spot to form various pattern effects.

Description

Hot spot cutting imaging system

Technical field

The utility model relates to the stage lighting field, is specifically related to be used for the hot spot cutting imaging system of stage lighting.

Background technology

At present, the Computer lamp of stage lighting industry realizes that the variation of spot pattern relies on pattern disk basically, and the quantity of pattern disk has determined the quantity of Computer lamp spot pattern, has bigger limitation.

Because pattern disk has certain volume and quality entities, thereby makes the use amount on Computer lamp limit to some extent, thereby causes the finiteness of Computer lamp spot pattern effect.

The hot spot cutting imaging system of the utility model can be through cutting the mating plate interoperation; Realize the Tong Guangkou of arbitrary shape; Light beam throws away through this logical light mouth and forms corresponding spot pattern; And can regulate the size of hot spot through the contraction of grating, thus greatly expanded the diversity and the flexibility of light spot shape, make stage lighting can be used for a greater variety of application scenarios.

The utility model content

The related a kind of hot spot cutting of the utility model imaging system, it can realize arbitrary shape through cutting the interoperation of mating plate, with the kind of Computer lamp hot spot by limited become unlimited maybe, thereby greatly enriched the spot pattern effect of Computer lamp.

The utility model comprises that mainly a plurality of mutually non-touching metals cut mating plate; Telescopic grating; A plurality of motors of cutting mating plate or grating action through gear driven etc.

According to the one side of the utility model, can the hot spot cutting imaging system of the utility model be fixed on the metallic support, through driven by motor, make hot spot cutting imaging system can on this support, carry out the rotation of certain angle.This metallic support mainly is to be used for fixing to support hot spot cutting imaging system, and four swiveling wheels are set this support and hot spot cuts into the picture system engages, makes hot spot cutting imaging system rotate.

Because the utility model can adopt above structure; Therefore can utilize the interoperation and accurate location of cutting mating plate easily; Block hot spot and form new spot pattern; The mating plate of cutting in the utility model can the flexible and swing in certain yardstick and angle, can form the logical light mouth of needed hot spot in any direction.Can great property versatile and flexible regulate hot spot through combining grating, making.

The utility model is simple in structure, accurate positioning, variation abundant, has satisfied the demand of light of stage to the hot spot modeling effect to a great extent.

The specific embodiment

The utility model relates to the hot spot cutting imaging system of using on a kind of stage lighting.According to an illustrative examples of the utility model, with shown in the accompanying drawing 2, comprising: 4 fan-shaped mating plate (1), grating (8), motor (9), (10), (11), (12), (13), (14) etc. of cutting for example like accompanying drawing 1.Accompanying drawing 3 is a kind of sketch map of cutting the mating plate structure of the utility model.But, obviously, it will be understood by those skilled in the art that the described mating plate (1) of cutting not only can be fan-shaped, and can make arbitrary shape according to actual needs.

With shown in the accompanying drawing 2, in fixing panel beating, connect the panel beating support (7) that square four summits are provided with swiveling wheel (4) like accompanying drawing 1, swiveling wheel (4) engages with the chassis of disk (3), under the drive of motor (10), and the rotation of realization disk (3).Catch capable of using has effectively stopped the swing of motor (10), and the rotation that comes limit disk (3) within the specific limits.Realize the pattern rotation thus.

Shown in accompanying drawing 1 and accompanying drawing 2; Connect foursquare four vertex positions in the profile in taking over a business of disk (3); For example 4 fan-shaped mating plates (1) of cutting are set; Separate and fixedly cut the relative position of mating plate (1) on disk (3) card normal direction by compressing tablet (2), fix the relative position on the card of cutting mating plate (1) by the guide rail copper post (6) that is fixed on the rotating disk.Four fan-shaped mating plates (1) of cutting are respectively by four groups of motor-driven, shown in accompanying drawing, and motor (11), motor (12), motor (13), motor (14).

As shown in Figure 1; Cooperate under the drive at every group of motor; Stretch in trend circle disk center direction by cutting mating plate (1), drive by the rotating disk that has guide rail copper post and cut mating plate (1) is cooked certain radian in the covering of the fan that with gear (5) is the summit swing with gear (5) drive of cutting mating plate (1) sawtooth interlock.

As shown in Figure 1, cutting mating plate (1) for 4 all can the flexible and swing in certain yardstick and angle, so can be in the needed spot pattern of any square formation.Through 4 fan-shaped mating plate (1) interoperations of cutting of driven by motor, just can realize that four limits are with the arbitrary shape of interior (being quadrangle and triangle), the spot pattern of any direction, like triangle, rhombus, rectangle etc.In conjunction with circular light hole, also can form the figure that has radian, as fan-shaped etc.

As shown in Figure 2, by the contraction of motor (9) drive grating (8), can change to realize the spot pattern size.

More than combine accompanying drawing and specific embodiment that the utility model has been carried out detailed description.But; Those skilled in the art are to be understood that; The above only is to illustrate and describe some specific embodiment, utilizes above embodiment only to be used for explaining the technical scheme of the utility model, therefore to the scope of the utility model; Especially the scope of claim does not have any restriction.The scope of the utility model is limited accompanying claims.
