When its installation plays the warning function of safe distance on a vehicle, static pattern is not easy to arouse people's attention, base of the present invention
Developed in this.
The content of the invention
The present invention exists for prior art projects the problem of a certain fixed pattern, effect show slightly dullness, proposes a kind of dynamic
State image projection system.
The concrete technical scheme of the present invention is as follows：A kind of dynamic image optical projection system, including：
Light source；
Optically focused convex lens, with light source disposed adjacent, the first emergent light is launched after converging light source；
Baffle plate can be compiled, the first emergent light for accepting the transmitting of optically focused convex lens, it is changed into the second emergent light after passing through；
Microlens array component, accepts the second emergent light, and it launches the 3rd emergent light after passing through；
Screen, accepts the 3rd emergent light, and form image；
Wherein, it is described to compile the cell shutter that baffle plate includes some array arrangements, by adjusting each cell shutter
Printing opacity is with blocking so that dynamic image is formed on screen.
It is preferred that the microlens array component includes according to light path：It is first microlens array, pattern panel, second micro-
Lens array, wherein, lenticule on two microlens arrays is corresponded, the pattern on pattern panel also with two microlens arrays one
One correspondence.
It is preferred that the cell shutter that can be compiled on baffle plate is corresponded with the lenticule on two microlens arrays.
Further, each cell shutter is to be made up of the flabellum of a motor controlling switch.
Further, each cell shutter is the liquid crystal panel controlled by drive circuit, drive circuit output control
The printing opacity of signal control liquid crystal panel processed and shading.
Further, each cell shutter is that a clear glass covers a light modulation film structure controlled by drive circuit
Into the printing opacity of drive circuit output control signal control light modulation film and shading.
It is preferred that the light source is LED/light source.
Use of the present invention can compile baffle plate, and printing opacity and the shading of each cell shutter are controlled in real time, for overall screen
Image can realize dynamic regulation so that the single display effect of image is overcome.

Embodiment
Below in conjunction with the drawings and specific embodiments, invention is described in detail.
Referring to figs. 1 to Fig. 2, the present invention provides a kind of dynamic image optical projection system, including：Light source 1, optically focused convex lens 2, can
Compile baffle plate 3, microlens array component 4, screen 5.Wherein, microlens array component 4 includes according to light path：First microlens array
41st, the lenticule on pattern panel 42, the second microlens array 43, two microlens arrays 41,43 is corresponded, pattern panel 42
On pattern also with two microlens arrays 41,43 correspond.
It is described to compile the cell shutter 31 that baffle plate 3 includes some array arrangements with continued reference to Fig. 1 and Fig. 2, pass through regulation
The printing opacity of each cell shutter 31 is with blocking so that dynamic image is formed on screen.Specifically, the light that LED/light source 1 is sent
Directional light (the first emergent light), then directional light (the second outgoing after it can compile baffle plate 3 are obtained after optically focused convex lens 2
Light), the first microlens array 41 is reached, pattern panel 42 is then passed through, the emergent light (of the second microlens array 43 is eventually passed
Three emergent lights) project on screen 5.A series of baffle plate array that baffle plate 3 is made up of cell shutters 31, each unit can be compiled
Baffle plate 31 has two functions of realizing the transmission of incident light and block, each cell shutter 31 can independent operating, pass through
The switching control (referring to Fig. 2, white represents printing opacity, and black represents shading) of each cell shutter 31 on baffle plate 3 pair can be compiled, can
To realize the orderly switching between the pattern on pattern panel 42, it is achieved thereby that the dynamic change of the image projected on screen.
