Description

A kind of optical projection means

Technical field

This utility model belongs to illumination processing field, and in particular to a kind of optical projection means.

Background technology

On stage lamp market, similar technique application is broadly divided into LED water wave lamps, LED blue sky and white cloud effects by effect at present Lamp, flame effect light fixture etc., such LED effects fitting structure are simple (universal relative to computer head moving lamp simpler, optical system Two optical glasss constitute projection camera lenses), the angle of visual field is big, the low advantage of cost.But such light fixture major defect is：Projection Beam angle relatively fixed (only focus function, it is impossible to realize freely scaling for spot pattern)；Definition when needing high-definition effect It is not high；Than relatively sharp, hard-edge is aerial with day at spot pattern edge of all kinds of effect disks after the projection of optical imagery eyeglass group The visual gap of the vaporific illusory true effect of white clouds is obvious；A kind of light fixture can only realize a kind of projection simulation effect.

Utility model content

For this purpose, technical problem to be solved in the utility model is to overcome prior art bottleneck, it is a kind of real so as to propose The optical projection means of existing natural environment atmosphere.

To solve above-mentioned technical problem, the utility model discloses a kind of optical projection means, the same center of described device Axle includes following structure from light incident direction order：Condenser lenss, shading diaphragm, effect disk, aspherical lens, the second biconvex mirror Piece.

Preferably, the condenser lenss are made up of non-spherical lens and the first biconvex eyeglass.

Preferably, the plane of incidence of the non-spherical lens is 8-10mm for the radius of curvature value of plane and exit facet.

Preferably, the radius of curvature value of the plane of incidence of the first biconvex eyeglass is 45-55mm and the curvature of exit facet half Footpath value is 20-25mm.

Preferably, the effect disk quantity is two, and two effect disks are placed up and down, and belong to a center Axle；An electric motor is provided between the effect disk and the shading diaphragm, the axostylus axostyle of the electric motor can drive The effect disk of side carries out coaxial rotating；The electric motor can also drive two effect disks to carry out transverse shifting, enter And reach two effect disks and mutually switch.

Preferably, the effect disk is the figuratum coated glass of surface stamp.

Preferably, the radius of curvature value of the plane of incidence of the aspherical lens is 248-257.5mm, the secondary song of exit facet Curvature radius value is 40-45mm.

Preferably, the radius of curvature value of the plane of incidence and exit facet of the second biconvex eyeglass is 128-136mm.

It is more highly preferred to, between biconvex eyeglass and shading diaphragm, is additionally provided with a colour disk.

Above-mentioned technical proposal of the present utility model has advantages below compared to existing technology：Device described in the utility model, Under the irradiation of LED light source, combined by geometry image opticss aspheric design and non-sequence optical technology, be capable of achieving 25- 45 ° of patterns are freely scaled, projection disk clearly with illusory effect free switching, optical system can accommodate more imaging things, and Multiple effect disks can be placed；With great market prospect and economic worth.

Description of the drawings

In order that content of the present utility model is more likely to be clearly understood, it is embodied as below according to of the present utility model Example simultaneously combines accompanying drawing, and this utility model is described in further detail, wherein

Fig. 1 is the structural representation of optical projection means described in embodiment 1.

Specific embodiment

Embodiment 1 present embodiment discloses a kind of optical projection means, described device with central shaft include from top to bottom as Lower structure：Condenser lenss (being made up of non-spherical lens 1 and the first biconvex eyeglass 2), colour disk 3,4, two effect disks of shading diaphragm are (front Effect disk 6, rear effect disk 7), aspherical lens 8, the second biconvex eyeglass 9.

The non-spherical lens 1 is plane for the plane of incidence and outgoing curvature radius value is the non-spherical lens of 8-10mm.

The first biconvex eyeglass 2 is 45-55mm for the radius of curvature value of the plane of incidence and outgoing curvature radius value is The biconvex eyeglass of 20-25mm.

Effect disk (front effect disk 6, the rear effect disk 7) quantity is two, is placed before and after two effect disks, and together Belong to a central shaft, between the effect disk and the shading diaphragm 4, be provided with an electric motor 5, the electric motor 5 Axostylus axostyle can drive top the effect disk carry out coaxial rotating；The electric motor 5 can also drive two effect disks Carry out transverse shifting, and then reach two effect disks mutually switching.

The effect disk is the figuratum coated glass of surface stamp.

The radius of curvature value of the plane of incidence of the aspherical lens 8 is 248-257.5mm, the quadratic surface curvature of exit facet Radius value is 40-45mm.

The radius of curvature value of the plane of incidence and exit facet of the second biconvex eyeglass 9 is 128-136mm.

Radius of curvature value mentioned above is radius of curvature.

Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.It is right For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or Change.There is no need to be exhaustive to all of embodiment.And thus it is extended obvious change or Among changing the protection domain created still in this utility model.
