Specifically, as shown in fig. 5, three light-emitting device connecting seats 21 penetrating through the inside of the barrel 2 are integrally arranged on the outer circumferential surface of the barrel 2, and the three light-emitting device connecting seats 21 are uniformly distributed on the outer circumferential surface of the barrel 2 along the circumferential direction, that is, an included angle between the axes of two adjacent connecting seats 21 is 120 °. The connecting base 21 is a hollow cylindrical shell, and the end part of the connecting base is provided with an external thread section.

As shown in fig. 6 and 7, the single monochromatic light emitting device 6 includes a light shielding cylinder 61, a lamp mounting base 62 fixedly connected to an end of the light shielding cylinder 61, and a white spotlight 63 fixedly disposed on the lamp mounting base 62 and located in the light shielding cylinder 61. The shading cylinder 61 is of a hollow cylindrical shell structure, and is also made of the same opaque material as the cylinder 2, so that the shading performance in the shading cylinder is ensured. Meanwhile, the inner wall of the light-shielding cylinder 61 is also provided with a light-reflecting layer as in the cylinder 2. The bottom end of the inner wall of the shading cylinder 61 is provided with an inner thread section which is matched and connected with an outer thread section at the end part of the connecting seat 21, so that the shading cylinder 61 is fixed on the connecting seat 21.

A monochromatic light-transmitting lens component 64 is movably inserted in the middle of the shading cylinder 61. As shown in FIG. 10, the single color light transmissive lens assembly 64 includes a lens mount 641 and a single color convex lens 642 embedded in the lens mount 641. Lens mounting bracket 641 is annular flat frame, has seted up the interface on the lateral wall of shading barrel 61, and the width of interface is the same with the thickness of lens mounting bracket 641, and the horizontal projection length of interface is greater than the bottom frame diameter of lens mounting bracket 641 for monochromatic printing opacity lens subassembly 64 can be by in the interface inserts shading barrel 61 directly. Preferably, the inner wall of the shading cylinder 61 is provided with an insertion groove corresponding to the insertion port, and the lens mounting bracket 641 is movably inserted into the insertion groove, so that the side surface of the upper half part of the inserted lens mounting bracket 641 is attached to the side wall of the insertion port, and the side surface of the lower half part is attached to the side wall of the vehicle control console, thereby ensuring a good sealing shading effect.

The monochromatic convex lens 642 comprises monochromatic convex lens sheets of three primary colors of red, green and blue, and when a white light beam generated by the white spotlight 63 impinges on the monochromatic convex lens 642, parallel light passes through the corresponding color convex lens 642, and then light rays of the corresponding color in a criminal field converge at a focus of the convex lens 642 close to one side of the cylinder 2. Preferably, the monochromatic lenticular sheet 642 is made in a more monochromatic series of progressively decreasing gradients of chroma to form more mixed colors.

The outer wall of the shading cylinder 61 is rotatably connected with a shading ring 65 which movably covers the outer side after the insertion. The shading ring 65 is in a semi-circular arc shape, the inner side of the shading ring is an elastic metal strip, and the outer side of the elastic metal strip is coated with a rubber layer. As shown in fig. 6 and 7, when the single-light monochromatic light emitting device 6 is used, the light shielding ring 65 is opened, so that the insertion port is exposed, and the monochromatic light transmitting lens assembly 64 can be inserted into the light shielding cylinder 61 through the insertion port; as shown in fig. 8, when the single-light single-color light emitting device 6 is not used, the single-color light transmitting lens assembly 64 is removed from the light shielding cylinder 61, and the light shielding ring 65 is fastened to the socket and fixed to the light shielding cylinder 61 by the deformation restoring force of the light shielding ring 65 itself, thereby ensuring the sealing and light shielding performance inside the light shielding cylinder 61.

As shown in fig. 9, the mirror assembly 7 includes a socket plate 71, and a lens fitting plate 72 fixedly connected to one end of the socket plate 71 and disposed obliquely above the socket plate 71, and a flat mirror 73 is fitted on a top surface of the lens fitting plate 72. As shown in fig. 5, a socket 22 matching with the plug board 71 is disposed on the inner wall of the cylinder 2, and the plug board 71 is detachably plugged into the socket 22. After plugging, the positions of the three light-emitting mirror assemblies 7 on the inner wall of the cylinder 2 are distributed as shown in fig. 3 and 4.

Preferably, the center point of the planar mirror 73 is located at the focus of the monochromatic convex lens 642 in the single monochromatic light emitting devices 6, and a connecting line between the center point of the monochromatic convex lens 642 and the center point of the planar mirror 73 and a connecting line between the center point of the projection screen plate 4 and the center point of the planar mirror 73 are symmetrically located on two sides of the normal line at the center point of the planar mirror 73, so that the light rays projected and converged on the planar mirror 73 by the monochromatic convex lens 642 are diffused and projected on the projection screen plate 4 according to the reflection rule of the plane mirror, that is, the light rays emitted by each single monochromatic light emitting device 6 are projected at the center of the projection screen plate 4 after being acted by the corresponding mirror assembly 7, as shown by the solid arrow with dashed line in fig. 3.

Thus, by providing the monochromatic convex lenses 642 of different or the same primary color in any two of the three single-light monochromatic light emitting devices 5, a superimposed effect of light rays of two lightness and/or two chroma can be formed on the projection screen 4. Through the opening of independent control knob switch 621, can demonstrate the respective projection effect of two kinds of monochromatic light, then two knob switches 621 of control open simultaneously, demonstrate the superimposed projection effect of two kinds of monochromatic light, realize the mixed colour effect demonstration that adds the method and mix. The three single-light monochromatic light emitting devices 5 can also be simultaneously provided with monochromatic light transmitting mirrors 642 of different primary colors to demonstrate the color mixing effect demonstration of the additive mixing of the three colors. Because each monochromatic light ray has certain lightness, the lightness is obviously enhanced after two or three monochromatic light rays are superposed. By adjusting the knob switch 621 independently, the brightness ratio of the three lights can be adjusted arbitrarily, thereby forming more different mixing effects.

As shown in fig. 3, the structure of the single multicolor light emitting device 5 is substantially the same as the structure of the single monochromatic light emitting device 6, except that: in the single-light multicolor light emitting device 5, three sockets are arranged on the light shielding cylinder 61, the three sockets are arranged at equal intervals along the axial direction of the light shielding cylinder 61, the distance between two adjacent sockets is twice of the focal length of the monochromatic convex lens 642, the distance between the central point of the monochromatic transparent lens 642 at the leftmost side and the central point of the projection screen 4 is also twice of the focal length of the monochromatic transparent lens 642, then the monochromatic transparent lenses 642 of the three primary colors of red, green and blue are respectively inserted into the three sockets, after the parallel white light at the right side is irradiated on the monochromatic convex lens 642 at the rightmost side, the focus at the left side of the monochromatic convex lens 642 is converged and inversely equally diffused to the right side of the monochromatic convex lens 642 at the middle, so that the parallel light with two-color mixture is formed at the left side of the monochromatic convex lens 642, and the parallel light is converged and inversely equally projected on the projection screen 4 through the monochromatic transparent lens at the leftmost side, that is, the light emitted from the single-light multicolor light emitting device 5 is projected at the center of the projection screen 4, so as to form a three-color mixed projection effect, as shown by the dotted-dashed hollow arrow in fig. 3.

Therefore, in the three single-light monochromatic light emitting devices 5, the monochromatic convex lenses 642 with three primary colors are sequentially inserted from left to right by turning on the knob switch, so that a monochromatic projection effect, a two-color superposition mixing effect and a three-color superposition mixing effect can be sequentially formed on the projection screen plate 4, and the color mixing effect demonstration of subtractive mixing is realized. Since the lightness of the original white light is fixed, the lightness of the original white light is reduced in sequence after the two or three monochromatic lights are superposed.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
