Abstract
The invention discloses a combined biprism structure of a stage lamp. The combined biprism structure has two polygon prisms. The combined biprism structure can show a light beam effect of a single polygon prism by itself, or can show a composed effect of a plurality of light beams using the two polygon prisms. The two polygon prisms can completely overlap when work in the same optical axis in a lamp, to generate N1 beam rings moving in the same direction. The two polygon prisms also can partially overlap to generate N2 beam rings moving in the same direction or opposite directions. The combined biprism structure can enlarge a whole light spot, the composite effect is greatly better than one prism, so the combined biprism structure can greatly make enrich and render a stage effect.
Description
Technical field
The invention belongs to stage illumination, lighting technical field, particularly relate to a kind of combination biprism structure of stage lighting.
Background technology
The hot spot effect of the Computer lamp of current stage lamp industry is more and more diversified, and the application of stage lamp is also more and more extensive.Prism becomes indispensable element gradually in stage lamp uses, and single beam or single pattern can get multiple hot spot and hot spot rotate effect by prism, has enriched stage effect greatly and has played up power.
But single prism has a limitation when getting effect, i.e. the unicity of effect and the limitation of spot size.What such as commonly use at present is 8 prisms, the light beam got or pattern can form 8 road light beams or 8 patterns by 8 prisms, if want 16 patterns, then need to reuse 1 16 prism, but the overall spot size that 16 prisms and 8 prisms are formed is the same.
Biprism of the present invention is combined as 2 polygon prisms, own patent is taken charge of: a kind of biprism for stage lamp combines on the basis of (ZL201420015618.0) at me, not only can get separately single polygon prism beam effect, 2 polygon prisms also can be used to get the composite effect of multiple tracks light beam together; When 2 polygon prisms work with optical axis in light fixture, 2 polygon prisms can be completely overlapping, produces N1 homodromous light beam circle; 2 polygon prisms also can be not exclusively overlapping, and producing N2 can in the same way also can the light beam circle of reverse movement relatively; Biprism combination has the effect of amplifying overall hot spot, and composite effect is far superior to single prism and patent: a kind of biprism for stage lamp combines the effect of (ZL201420015618.0), enriches greatly and has played up stage effect.
Summary of the invention
For achieving the above object, the present invention by the following technical solutions.
A combination biprism structure for stage lighting, is characterized in that, described biprism is combined as 2 polygon prisms; Described 2 polygon prisms are all positioned at above light source in stage lamp, are in stage lamp lamp body head.
The limit number of described polygon prism is that N, N are more than or equal to 2.
2 described polygon prisms are positioned at different planes on stage lamp optical axis direction, and this plane orthogonal is in optical axis.
2 described polygon prisms all can move separately in stage lamp vertical optical axis plane.
2 described polygon prisms can be positioned on optical axis direction simultaneously.
2 described polygon prisms can bidirectional-movement in stage lamp.
When 2 described polygon prisms work with optical axis in light fixture, 2 polygon prisms can be completely overlapping, produces N1 homodromous light beam circle; 2 polygon prisms also can be not exclusively overlapping, and producing N2 can in the same way also can the light beam circle of reverse movement relatively.
The individual moving-beam circle in the same way of described N1, N1 is more than or equal to 1; Described N2 in the same way also can the light beam circle of reverse movement relatively, and N2 is more than or equal to 2.
N1 or N2 described light beam circle refers to the aperture be made up of N3 road beam effect; Described N3 road beam effect, N3 is more than or equal to 2.
This biprism structure has following characteristics: not only can get separately single polygon prism beam effect, and 2 polygon prisms also can be used to get the composite effect of multiple tracks light beam together; When 2 polygon prisms work with optical axis in light fixture, 2 polygon prisms can be completely overlapping, produces N1 homodromous light beam circle; 2 polygon prisms also can be not exclusively overlapping, and producing N2 can in the same way also can the light beam circle of reverse movement relatively; Biprism combination has the effect of amplifying overall hot spot, and composite effect is far superior to single prism, enriches greatly and has played up stage effect.

Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
As shown in Figure 1, in the use of actual light fixture, it is inner that 8 prisms (4) and 16 prisms (5) are arranged on rotating prism dish (6), rotating prism dish (6) is connected with light fixture lamp body, and 2 rotating prism dishes (6) are positioned between passing through plate (2) and camera lens (7); Rotating prism dish (6) can be swung by drive motors in optical axial plane, gear structure in the middle of rotating prism dish (6) simultaneously, by the transmission of motor-driven gear, 8 prisms (4) and 16 prisms (5) can also carry out bidirectional-movement in mounting groove; When 2 rotating prism dishes (6) swing to centre by drive motors, 8 prisms and 16 prisms all in the direction of the optical axis and be positioned at light hole (3) top, now can get the effect of composite prism; When motor drives 16 prism rotating discs or 8 prism rotating discs get time, now only 8 prisms or 16 prisms are positioned on optical axis, now can get 8 independent prismatic effect or 16 prism movement effects.
As shown in Figures 2 and 3, biprism in the present invention is combined as 18 prism (4) and 1 16 prism (5), two prisms are positioned at the front of light source (1) and passing through plate (2), and are in the different plane of vertical optical axis; As shown in Figure 2, when 8 prisms (4) and 16 prisms (5) are completely overlapping, the light beam that light source (1) sends forms light beam by light hole (3), light beam irradiation is on 8 prisms (4), because point light action of 8 prisms (4), 1 road light beam is originally divided into 8 light beams, and beam angle is dispersed and become large; Article 8, light beam is irradiated on 16 prisms (5) again, is again split, and becomes 24 light beams by 8 light beams; Namely, after adding 8 prisms (4) and 16 prisms (5), 1 light beam originally becomes the light beam circle of 24 light beam compositions, and beam angle obviously amplifies.
As shown in Figure 3, when 8 prisms (4) and 16 prisms (5) are not exclusively overlapping, the light beam that light source (1) sends forms light beam by light hole (3), light beam irradiation is on 8 prisms (4), because point light action of 8 prisms (4), 1 light beam is originally divided into 8 light beams, and beam angle is dispersed and become large, produces a light beam circle 1 be made up of 8 light beams; The light beam that light source (1) sends forms light beam by light hole (3), and light beam irradiation, on 16 prisms (5), becomes 16 light beams by 1 light beam, produces a light beam circle 2 be made up of 16 light beams; Namely after adding 8 prisms (4) and 16 prisms (5), 1 light beam originally becomes 24 light beams and forms 2 light beam circles, and beam angle obviously amplifies, the light beam circle 1 of 8 light beam compositions is in outer ring, and the light beam circle 2 of 16 light beam compositions is at inner ring; Light beam circle 1 and light beam circle 2 can move in the same way, also can reverse movement relatively.
In sum, the present invention is in the practical application of stage lamp, both independent polygon prism effect can have been beaten, also the composite prism effect of biprism can be beaten, and the hot spot angle after biprism compound increases greatly, can form multiple can moving in the same way also can the light beam circle of reverse movement relatively, has enriched stage greatly and has played up power.
Above embodiment is only be described further technical scheme of the present invention, but not limits the scope of the invention.For one of ordinary skill in the art, to any apparent change that it does under the prerequisite not deviating from essence of the present invention, all by formation to infringement of patent right of the present invention, corresponding legal liabilities will be born.
