Embodiment one

As shown in Figure 1, projection arrangement provided by the embodiment of the utility model, light source 1, transparency 2 and lens 3, transparency 2 It is respectively positioned on lens 3 in the optical path of light source 1, for the focal length of lens 3 greater than 0, the positional relationship of light source 1 and lens 3 meets formula:Wherein, E is the distance between light source 1 and lens 3, and unit is centimetre；D is the focal length of lens 3, unit For centimetre.

Specifically, light source 1 is point light source, such as LED light, for emitting beam, and exposes to light through transparency 2 Lens 3；Transparency 2 is translucent or all-transparent, and is equipped with pattern.Transparency 2 is arranged between light source 1 and lens 3, works as light When through transparency 2, brightness corresponding with pattern or color is presented in each light beam, and each light beam is reflected through lens 3 again, to make light beam Direction of transfer changes, and when light beam projects on metope or perspective plane 8, the image on perspective plane 8 shows overlapping or deformation effect Fruit, thus, it is possible to show 3 D stereoscopic image；Alternatively, lens 3 are arranged between light source 1 and transparency 2, across lens 3 Light generates convergence, and the light converged passes through transparency 2, along the radial direction of lens 3, supports or opposes from the axis close to lens 3 The axis angle of axis direction from lens 3, light and lens 3 is incremented by, light through the light of transparency 2 be radiated at metope or When on perspective plane 8, along the radial direction of lens 3, from the axis close to lens 3 to the axis direction for deviating from lens 3, metope or throwing Image superposition effect on shadow face 8 is incremented by, and so that image border is showed overlapping or deformation, and then show 3 D stereo shadow Picture.

As shown in Fig. 2, the positional relationship of transparency 2 and lens 3 meets following formula in the range of 3-dimensional image area 6:In the range of non-special efficacy area 7, the positional relationship of transparency 2 and lens 3 meets following formula:Wherein, E is the distance between light source 1 and lens 3, and D is the focal length of lens 3, and light beam projects metope at this time Or the deformation pattern or pattern-free of two-dimensional pattern, distortion are showed on perspective plane 8.

In the utility model embodiment, projection arrangement includes reflective sleeve 4, and light source 1 and reflective sleeve 4 are coaxial, and even It connects in reflective sleeve 4.Specifically, internal diameter of the reflective sleeve 4 close to 2 one end of transparency is greater than in 2 one end of transparency Diameter, reflective 4 inner sidewall of sleeve are equipped with mirror surface, for the light that reflection source 1 issues, so that it is guaranteed that the light edge that light source 1 issues The axis direction of reflective sleeve 4 is transmitted towards transparency 2 and lens 3.Light source 1 is plugged in reflective sleeve 4, can by push-and-pull light source 1 So that light source 1 is slided along the axis direction of reflective sleeve 4, change position of the light source 1 in reflective sleeve 4, so as to change The beam diameter spread out of by reflective sleeve 4.When light source 1 is along the axis direction of reflective sleeve 4, towards the direction close to transparency 2 When mobile, it is gradually reduced by the beam diameter that reflective sleeve 4 is spread out of；When light source 1 is along the axis direction of reflective sleeve 4, towards back When direction from transparency 2 is mobile, it is gradually increased by the beam diameter that reflective sleeve 4 is spread out of.Pass through reflective set by changing The beam diameter of 4 outflow of cylinder, so as to so that the pattern magnitude on beam diameter and transparency 2 is adapted.

As shown in figure 3, projection arrangement includes camera lens frame 5, transparency 2 and lens 3 are connect with camera lens frame 5.Wherein, it projects Piece 2 is detachably connected with camera lens frame 5, has the transparency 2 of different pattern by replacing, and be can be realized and is projected to different pattern.

Further, reflective sleeve 4 includes: sleeve body 41 and girth sheets 42, and girth sheets 42 is connect with sleeve body 41；Camera lens Annular slot 51 is equipped in frame 5, girth sheets 42 is plugged in annular slot 51.Wherein, it is semicircular ring that camera lens frame 5, which includes two sections, The framework of shape, it is circular camera lens frame 5 that two frameworks, which are spliced to form section, and girth sheets 42 is sheathed in annular slot 51, To realize the connection of reflective sleeve 4 and camera lens frame 5.Light is transferred to projection along the axis direction of reflective sleeve 4 and camera lens frame 5 Piece 2 and lens 3 can be scattered by reflective sleeve 4 with camera lens frame 5 to avoid light.

As shown in Fig. 3, Fig. 4 and Fig. 5, first annular plate 52 and the second annular version 53 are connected in camera lens frame 5, it is first annular The interior diameter of the annular slot 51 of formation between plate 52 and the second annular version 53, first annular plate 52 and the second annular version 53 is respectively less than The overall diameter of the overall diameter of girth sheets 42, first annular plate 52 and the second annular version 53 is all larger than the overall diameter of girth sheets 42, the first ring Shape plate 52 and the interior diameter of the second annular version 53 are all larger than the overall diameter of sleeve body 41.Reflective sleeve 4 is manually operated, makes girth sheets 42 slide along annular slot 51, and then reflective sleeve 4 can be made to move along the radial direction of camera lens frame 5, to change light warp Reflective sleeve 4 is irradiated to the position of transparency 2.With the mobile reflective sleeve 4 of slow speed, through the light of same position on pattern Beam, the incident angle for being irradiated to lens 3 within a certain period of time is different, so that the light beam be made to be irradiated on metope or perspective plane 8 Position changes.For circular pattern is set on transparency 2, when reflective sleeve 4 is mobile relative to transparency 2, projection Sphere image on to metope or perspective plane 8 shows the pattern of rolling, so as to form dynamic 3-D effect.

Further, the diameter of transparency 2 and lens 3 is all larger than the interior diameter of sleeve body 41.So that it is guaranteed that through sleeve The light that ontology 41 is spread out of can be irradiated to transparency 2 and lens 3, have reached making full use of for light, light is avoided to irradiate Lead to device heating to shading object.

As shown in fig. 6, reflective sleeve 4 is plugged in camera lens frame 5, flexible driving group is equipped between reflective sleeve 4 and camera lens frame 5 Part 9, flexible driving assembly 9 is for driving reflective sleeve 4 to move along the radial direction of camera lens frame 5.It can by flexible driving assembly 9 To drive flexible driving assembly 9 to move along the radial direction of camera lens frame 5, and then change the light for being irradiated in same position on pattern It is transferred to the incident angle of lens 3, dynamic 3-D graphic is consequently formed.

Further, the driving assembly 9 that stretches includes: the first telescoping cylinder 91 and the second telescoping cylinder 92, the first telescoping cylinder 91 Axis is vertical with the axis of the second telescoping cylinder 92；First telescoping cylinder 91 is hinged on reflective sleeve 4 and camera lens by the first articulated shaft Between frame 5；Second telescoping cylinder 92 is hinged between reflective sleeve 4 and camera lens frame 5 by the second articulated shaft；The axis of first articulated shaft The axis of line and the second articulated shaft is parallel with the axis of reflective sleeve 4.It is stretched by the first telescoping cylinder 91 and the second telescoping cylinder 92 Long or shortening, can be such that reflective sleeve 4 moves along the radial direction of camera lens frame 5, to realize that the image on transparency 2 is mapped in Metope or the overturning of the enterprising Mobile state in perspective plane 8.

Embodiment two

Projecting method includes the following steps:
