Abstract
The utility model relates to a raster type light concentrator with equal distance, and more especially, an optical structure system substitutes to a cylindrical lens and the utility model belongs to an optical component. The utility model mainly adopts that step grooves are arranged on a main body of the raster type light concentrator in an equal distance arrangement mode, and the width of the groove distance of the step grooves is 0.05 to 10MM. The utility model has the advantages of simple, compact and reasonable structure, light weight, small size, low cost, simple manufacture technology, large light passing caliber and convenient mass production, and furthermore, the step groove-shaped surface of a prism changes the direction of propagation of light, concentrates the energy of line-shaped light spots and performs the action of a lens.
Description
Technical field
The utility model relates to a kind of equidistant raster pattern condenser, specifically is used for the optical texture system and substitutes cylindrical lens, belongs to optics.
Background technology
Before the utility model was made, in prior art, the raster pattern condenser that is used for the optical texture system normally adopted cylindrical lens, and cylindrical lens is the semicircular pillar sphere.The cylindrical lens Heavy Weight of this kind structure, the price height, complex manufacturing technology, the cycle is long, uses inconvenience is installed.
Technology contents
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; In light weight, volume is little, low price, manufacture craft are simple, clear aperture is big, the equidistant raster pattern condenser of being convenient to produce in enormous quantities.
Main solution of the present utility model is achieved in that
The utility model adopts the equidistant step trough 2 that is shaped on raster pattern condenser main body 1.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; In light weight, volume is little, low price, manufacture craft are simple, clear aperture is big, is convenient to produce in enormous quantities; In optical system, have prism ladder flute profile surface to change the direction of propagation of light, converge the wire light spot energy, and can play lensing.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model is mainly processed on numerically-controlled machine.Employing is the equidistant step trough 2 that is shaped on raster pattern condenser main body 1, and the width of its step trough 2 slot pitches is: 0.05-10mm.Utilize numerically-controlled machine alloy sheets to be processed into raster pattern condenser mould according to the data of the ladder corrugated surface of optics requirement, the thermoplastic in hot press with optical plastic and condenser mould then, and pressurize typing in chilling press, can produce the raster pattern condenser, therefore, help the mass production of product.The utility model simultaneously, also can be applied to the solar energy system aspect not only as a kind of optical element, by refraction optically focused be used for improving solar energy density, thereby can improve the utilization ratio of sun power.
