Abstract
The utility model relates to the field of annular optical technology, in particular to an optical annular prism used on the optical path in an optical instrument. The optical annular prism is characterized by comprising a cylindrical surface, an inclined surface and another inclined surface, wherein an included angle Alpha between one of the inclined surfaces and the cylindrical surface is 70-80 degrees; and an included angle Beta between the other inclined surface and the cylindrical surface. Compared with the prior art, the optical annular prism has not only a 30-percent wide visible visual angle and a high optical gain effect, but also a soft-light effect, thereby avoiding optical unevenness caused by a smooth-surface light source, and achieving an energy-saving effect.
Description
Technical field
The utility model relates to circular optical technical field, specifically a kind of optics circle prism that is used on the optical instrument light path.
Background technology
The optical frames of present domestic use is to utilize optical total-reflection and refraction effect mostly, and in-plane scatter light is carried out polymerization to a certain degree, and its brightness effects is poor, and the light of total reflection is not recycled, and energy resource consumption is big.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of optics circle prism is provided.
In order to achieve the above object, the utility model has designed a kind of optics circle prism, it is characterized in that: comprise the face of cylinder, inclined-plane and another inclined-plane; The angle on the described inclined-plane and the face of cylinder is α=70～80 °, and the angle on another inclined-plane and the face of cylinder is β=20～30 °.
The utility model is compared with prior art, not only has 35% wide visible visual angle, high gain of light effect, and have the sheen effect, avoid optics inequality property, and have energy-saving effect by the generation of light area source.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model side view.
Referring to Fig. 1 and Fig. 2,1 is the face of cylinder; 2 is ramp; 3 is another inclined-plane.
Embodiment
Combine accompanying drawing that the utility model is further specified at present.
As depicted in figs. 1 and 2, the utility model comprises the face of cylinder 1, inclined-plane 2 and another inclined-plane 3; During best enforcement, the angle on inclined-plane 2 and the face of cylinder 1 is α=75 °, and the angle on another inclined-plane 3 and the face of cylinder 1 is β=21 °.The utility model can obtain producing light refraction at two-dimensional directional at least, so that produce good optically focused phenomenon, and has energy-conserving action.
