A kind of prism for stage illumination, lighting

Technical field

The utility model belongs to stage illumination, lighting field, and in particular to a kind of prism for stage illumination, lighting.

Background technology

Present stage public place of entertainment is to make the strong lighting effects of beam pattern third dimension using computer head moving lamp, it will usually Design addition prism in the optical path, and using prism light splitting dioptric imaging principle process faceted pebble quantity not etc., refraction angle The optical glass prism not waited.By unusual point two kinds of shape and spectrophotometric result：One kind is multiaspect (more than three faceted pebbles) Conical prism.Second is the trapezoidal linear prisms of multiaspect, also referred to as arranges mirror (more than 4 planes of refraction).Conical prism can basis Actual use situation design faceted pebble quantity and angle, it is that light beam third dimension is strong, color pattern is rich and changeful that its effect is specific, is mesh The most widely used effect class optical element of preceding computer pattern and sealed beam lamp.Trapezoidal row's mirror on one piece of optical glass face by designing The straight flat luminous refraction of the continuous adjacent with different refraction angles is processed, its effect feature is projected by rotary rowed mirror Spot pattern out has very strong 3D stereoeffects, and such eyeglass is mainly used in computer sealed beam lamp.But major defect is One desk lamp tool, which will such as place two kinds of prisms, will cause that light path stroke is lengthened, structure design is more complicated, light fixture cost is higher.

Utility model content

Therefore, technical problem to be solved in the utility model be to overcome in the prior art two kinds of prisms will cause light path Stroke is lengthened, the technical bottleneck that structure design is more complicated, light fixture cost is higher, so as to propose a kind of to combine cone Prism and straight line arrange the novel prism of mirror optical characteristics；Solve fitting structure complexity and reduce cost, while utility model is created New stage-lighting effect is gone out.

In order to solve the above technical problems, the utility model discloses a kind of prism for stage illumination, lighting, the prism is Lens, are divided into the plane of incidence and exit facet；The exit facet is plane；The plane of incidence is faceted pebble, and homogeneous radiation is provided with 4- 32 project in fan-shaped refracting sphere with horizontal plane；The 4-32 refracting sphere is adjacent two-by-two, shape is identical and with horizontal plane Projection is collectively forming a concentric circles；

Centered on the summit of the faceted pebble, at least three folding is disposed with along radiation direction on each refracting sphere Penetrate face；The angle of the relatively described exit facet of the adjacent plane of refraction, along radiation direction in continuous cumulative big, the plane of refraction Angle is 6-25 °.

It is preferred that, the quantity of the refracting sphere is 8.

It is preferred that, the quantity of the plane of refraction on each refracting sphere is 3.

It is preferred that, the angle order of three planes of refraction on the same refracting sphere is 6 °, 12 °, 18 °.

It is preferred that, a diameter of 45-65mm of the prism.

It is preferred that, the refractive index of the prism is 1.47-1.75.

It is more highly preferred to, described prism is optical glass.

Above-mentioned technical proposal of the present utility model has advantages below compared with prior art：It is described in the utility model to be used for The prism of stage illumination, lighting, integrates strong stereoscopic beam sense and pattern 3D effect；A kind of prism can realize two kinds of prisms Effect, simplifies structure, cost is reduced；With great market prospects and economic value.
