Background technology
Present stage public place of entertainment is to make the strong lighting effects of beam pattern three-dimensional sense using computer head moving lamp, it will usually
Design addition prism in the optical path, and process that faceted pebble is in varying numbers, refraction angle using the light splitting dioptric imaging principle of prism
The optical glass prism not waited.It is divided to two kinds by shape and the unusual of 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 designs faceted pebble quantity and angle, and specific effect is that light beam three-dimensional sense is strong, color pattern is rich and changeful, is mesh
Preceding computer pattern and the most widely used effect class optical element of 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, effect feature is projected by rotary rowed mirror
Spot pattern out has very strong 3D stereoscopic effects, 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 lengthens, structure design is more complicated, lamps and lanterns cost higher.
The content of the invention
For this purpose, the technical problems to be solved by the invention be to overcome in the prior art two kinds of prisms will cause light path stroke
Lengthen, structure design is more complicated, the higher technical bottleneck of lamps and lanterns cost, so as to propose a kind of to combine conical prism
With the novel prism of straight line row's mirror optical characteristics；It solves fitting structure complexity and reduces cost, while innovation and creation have gone out newly
Stage-lighting effect.
In order to solve the above technical problems, the invention discloses a kind of prism for stage illumination, lighting, the prism is lens,
It is divided into the plane of incidence and exit facet；The exit facet is plane；The plane of incidence is faceted pebble, and homogeneous radiation be provided with 4-32 with
Horizontal plane projection is in fan-shaped refracting sphere；The 4-32 refracting sphere is adjacent two-by-two, shape is identical and the projection with horizontal plane is total to
With one concentric circles of formation；
Centered on the vertex 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 °.
Preferably, the quantity of the refracting sphere is 8.
Preferably, the quantity of the plane of refraction on each refracting sphere is 3.
Preferably, the angle order of three planes of refraction on the same refracting sphere is 6 °, 12 °, 18 °.
Preferably, a diameter of 45-65mm of the prism.
Preferably, the refractive index of the prism is 1.47-1.75.
It is more highly preferred to, the prism is optical glass.
The above technical solution of the present invention has the following advantages over the prior art：It is of the present invention to be used for stage illumination, lighting
Prism, integrate strong stereoscopic beam sense and pattern 3D effect；A kind of prism can realize the effect of two kinds of prisms, make knot
Structure is simplified, cost reduction；With great market prospects and economic value.
