Description

Technical Field

[0001] This application relates to the technical field of light-emitting structures, and particularly to an optical structure presenting variable three-dimensional effects. Background Art

[0002] In existing vehicle headlights, in order to present a three-dimensional effect, a thick-wall part is usually used for light emission or a light-emitting surface stacking scheme is adopted to achieve this. This imaging method for presenting a three-dimensional effect has a single imaging effect. If you want to change the presented three-dimensional effect, it can only be achieved by replacing the thick-wall part or the light-emitting stacking surface. Summary of the Utility Model

[0003] The technical problem to be solved by this utility model is that the three-dimensional effect of the existing vehicle headlight structure capable of presenting a three-dimensional effect is single.

[0004] To this end, this utility model provides an optical structure presenting variable three-dimensional effects.

[0005] The technical solution adopted by this utility model to solve its technical problems is as follows:

[0006] An optical structure presenting variable three-dimensional effects, comprising,

[0007] A light source, and

[0008] A lamp cover, on which a light-emitting surface is provided, and an optical pattern is provided on the light-emitting surface. The lamp cover receives the light emitted by the light source and emits the light from the light-emitting surface. The optical pattern refracts the light emitted by the light source into the air and converges to form a three-dimensional pattern with a three-dimensional effect.

[0009] Further, the etching depth of the optical pattern is 1 - 2 microns.

[0010] Further, multiple optical patterns are provided to form multiple three-dimensional patterns with three-dimensional effects, and the multiple three-dimensional patterns form a linear light.

[0011] Further, the multiple optical patterns are arranged horizontally or vertically, and the multiple three-dimensional patterns form a horizontal or vertical linear light.

[0012] Further, the multiple optical patterns are arranged at intervals or staggered.

[0013] Further, there is an angle between the light-emitting direction of the light source and the plane where the optical pattern is located.

[0014] The beneficial effect of this utility model is that through a brand-new lamp cover design, the scheme has a simple structure and does not require component replacement. By changing the observer's angle, the display of multiple three-dimensional effect images can be achieved.

[0015] In the present solution, the lampshade and pattern design use fewer LEDs, reducing costs. Since the overall optical system is simple, the number of parts is reduced, costs are lowered, and the production yield is increased. Description of the Drawings

These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] An optical structure presenting a variable three-dimensional effect includes a light source 1 and a lampshade 2. The lampshade 2 is provided with a light-emitting surface, and an optical pattern 3 is engraved on the light-emitting surface. The light emitted from the light source 1 enters the lampshade 2, and then is refracted by the optical pattern 3 into the air, gathering to form a three-dimensional pattern 4 with a three-dimensional effect. The three-dimensional pattern 4 has a three-dimensional effect at all angles. By observing the three-dimensional pattern 4 from different angles, light at different angles of the three-dimensional pattern 4 can be obtained, thereby achieving a variable three-dimensional light effect.

[0029] As Figure 3 and Figure 4 shown, when seeing the three-dimensional pattern 4, the light in area a enters the right eye, and the light in area b enters the left eye, forming an image A. When seeing the three-dimensional pattern 4 from another angle, the light in area a' enters the right eye, and the light in area b' enters the left eye, forming an image B. Thus, by observing the three-dimensional pattern 4 from different angles, different three-dimensional effects can be obtained. Figure 5 Pictures showing the three-dimensional pattern 4 with a three-dimensional effect obtained from different angles are presented. The dashed line in the figure is the central axis passing through the three-dimensional pattern 4, with the optical pattern 3 Figure 5 The small figure a in it shows a picture of the three-dimensional pattern 4 with a three-dimensional effect obtained directly above the optical pattern 3, that is, on the central axis. Figure 5The small figure b therein is a picture of the three-dimensional pattern 4 with a three-dimensional effect obtained at a perspective rotated by 5° with the center point of the three-dimensional pattern 4 as the axis. Figure 5 The small figure c therein is a picture of the three-dimensional pattern 4 with a three-dimensional effect obtained at a perspective rotated by 10° with the center point of the three-dimensional pattern 4 as the axis. Figure 5 The small figure d therein is a picture of the three-dimensional pattern 4 with a three-dimensional effect obtained at a perspective rotated by 15° with the center point of the three-dimensional pattern 4 as the axis.

[0030] It should be noted that the etching depth of the optical pattern 3 on the surface of the lampshade 2 is 1-2 microns. Since the etching depth is shallow, the size of the pattern is small. The pixel points of the three-dimensional image 4 formed by the light emitted through the optical pattern 3 in the air are also small, and the three-dimensional visual effect of the three-dimensional image 4 is better. The optical pattern 3 needs to be realized through an ultra-precision processing technology. For the purpose of understanding the principle, the attached drawings in the embodiment are conceptual explanatory drawings, and the size and position of the lampshade 2, the number of light rays, the positional relationship between the eyes and the lampshade 2, etc. are different from the actual situation.

[0031] In this embodiment, the light source 1 is realized by using an LED light source 1. In other embodiments, the light source 1 can be realized by a non-LED light source 1, including but not limited to light sources 1 such as bulbs and lasers; it can also provide light through other optical systems, including but not limited to reflective and direct-emitting types. In addition, referring to Figure 2 , the light-emitting direction of the light source 1 can be set along the plane where the optical pattern 3 is located, or there can be an angle between the light-emitting direction of the light source 1 and the plane where the optical pattern 3 is located.

[0032] The optical pattern 3 can be provided in more than one place, and multiple optical patterns 3 can be arranged in a horizontal or vertical or rectangular array manner. Referring to Figure 6 , Figure 4 In , multiple optical patterns 3 are arranged horizontally and are staggered with each other, and the multiple three-dimensional patterns 4 formed form a horizontal linear light. Referring to Figure 7 , multiple optical patterns 3 are arranged vertically and are spaced apart from each other, and the multiple three-dimensional patterns 4 formed form a vertical linear light.

[0033] The implementation principle of this application is as follows:

[0034] After the light emitted by the light source 1 reaches the optical pattern 3, the optical pattern 3 reflects the light emitted by the light source 1, and the light reflected by the optical pattern 3 converges in the air to form a three-dimensional pattern 4 with a three-dimensional effect, so as to form a Fresnel effect. Furthermore, by observing the three-dimensional pattern 4 from different angles, the light at different angles of the three-dimensional pattern 4 can be obtained, thereby realizing a variable three-dimensional light effect.

[0035] In summary, through the design of an optical pattern 3, the solution has a simple structure and does not require component replacement. By changing the observer's angle, a variety of three-dimensional effect images can be presented.

[0036] This solution uses a small number of LEDs, reducing costs. Since the overall optical system is simple, the number of parts is reduced, costs are lowered, and the production yield of good products is increased.

[0037] Taking the above ideal embodiments of the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
