[0034] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0035] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, for example, the term "connection" can be a fixed connection, or a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or an internal communication of two elements or an interaction relationship between two elements. For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0036] Referring to Figures 1-2 , a thick-walled piece optical system for realizing functional multiplexing according to the embodiment of the present application can be applied to the optical structure 4 in the form of a thick-walled piece of a condenser 2 or a thick-walled piece of a mirror. The present application is exemplified as applied to a thick-walled piece structure of a condenser 2, which includes a light source 1, a condenser 2, and a light outlet 3, and the light source 1 is correspondingly arranged at the focal point of the condenser 2. The thick-walled piece structure has a light outlet, and a total reflection surface is arranged in the thick-walled piece structure, so that the incident light emitted by the light source enters the thick-walled piece structure and is reflected by the total reflection surface arranged therein, and then is emitted from the light outlet.

[0037] Specifically, in order to improve the light emitting effect, a pattern or a skin structure can be arranged on the light emitting surface of the light outlet 3, and the light source 1 used is not limited in color, which can be red, white, yellow, etc., or a combination of multiple color light sources 1, and the thick-walled piece structure can be made of transparent PMMA material or PC material.

[0038] More specifically, referring to Figures 3-5 In the present application, the light source 1 used at least includes a first light source (A) 11 and a second light source (B) 12, and the first light source (A) 11 and the second light source (B) 12 are arranged at intervals, for example, the first light source (A) 11 is red, and the second light source (B) 12 is green, and then a red-green-red-green light source combination is formed in sequence. Of course, the first light source (A) and the second light source (B) can also be set as yellow, white, or other different colors or the same color light source. And the first light source (A) 11 and the second light source (B) 12 are respectively arranged at the focal points of the corresponding condensers 2, so as to improve the light emitting efficiency of the overall optical system. It should be noted that the first light source (A) 11 and the second light source (B) 12 share the same light outlet, and the number of the first light source (A) 11 and the second light source (B) 12 and the spacing therebetween can be adjusted according to actual needs, so as to form different light emitting effects.

[0039] Referring to Figures 6-7, the light emitting part 3 is provided with a plurality of optical structures 4, the plurality of optical structures 4 includes first optical structure 41 and second optical structure 42, the first optical structure 41 and the second optical structure 42 are arranged on the exit path of the emitted light emitted by the light source 1, and the first optical structure 41 and the second optical structure 42 are arranged in staggered arrangement, so as to diffuse the emitted light emitted by the light source 1 through the first optical structure 41 and the second optical structure 42.

[0040] Referring to Figure 8 , specifically, the first optical structure 41 and the second optical structure 42 each include a plurality of first optical parts 421 and second optical parts 422, and the first optical part 421 and the second optical part 422 are sequentially connected in a hexagonal structure. The incident direction of the incident light of the light source 1, the first optical part 421 and the light emitting surface of the light emitting part 3 are arranged in parallel. Here, the length of the first optical part 421 is 1mm, the length of the second optical part 422 is 2.4mm, and the distance L1, L3 between adjacent second optical structures 42 is 5.24mm, that is, the distance between adjacent second optical structures 42 and first optical structures 41 is equal, and the diameter of the hexagonal optical structure is L4 is 4.2mm, that is, the length L4 between the opposite angles of the first optical structure 41 and the second optical structure 42 is less than the distance L1, L3 between adjacent first optical structures 41 and second optical structures 42. The hexagonal optical structure is arranged in a center-symmetric manner along its geometric center. It should be noted that in actual application, the angle and length between the first optical part 421 and the second optical part 422 can be adjusted according to the requirements, and the number of the first optical part 421 and the second optical part 422 can also be adjusted according to the requirements, so as to form optical structures 4 of different shapes.

[0041] More specifically, the first optical part 421 and the second optical part 422 of the first optical structure 41 and the second optical structure 42 are all total reflection surfaces. The first optical structure 41 is adapted to totally reflect the incident light emitted by the first light source (A) 11 to the second optical structure 42, and the second optical structure 42 is adapted to totally reflect the incident light reflected by the first optical structure 41 and emit it, so as to simultaneously light the light emitting port corresponding to the first light source (A) 11 and the second light source (B) 12.

[0042] Taking the second light source (B) 12 as an example, its main light path is divided into two modules, the first module hits the first optical structure 41, which can be divided into three parts, in order to facilitate the description, therefore, the optical part (total reflection surface) of the first optical structure 41 and the second optical structure 42 is further subdivided, specifically as Figure 9The first part of the light entering the thick-walled structure structure is reflected by the total reflection surface 1-2 and then enters the air, and then is emitted from the light exit surface of the thick-walled structure; the second part of the light is totally reflected by the total reflection surface 6-2, and then is totally reflected by the total reflection surface 3-1, and then is emitted from the light exit; the third part of the light is totally reflected by the total reflection surface 2-2, and then is totally reflected by the total reflection surface 5-3, and then is emitted from the light exit.

[0043] Similarly, the second module is hit into the second optical structure 42, and also three parts, the light path is the same, and will not be described in detail. The incident light emitted by the first light source (A) 11 is the same. As can be seen, after the second light source (B) 12 is emitted, not only can it light up the corresponding light exit in front of it, but also can light up the light exit in front of the first light source (A) 11, that is, it can light up the entire light exit, and the distance of the light source 1 of the same color can be set to 2 times of the traditional form, thereby effectively saving the light source 1, and reducing the cost and power consumption, and after multiple internal reflections, the lighting effect is more uniform.

[0044] In addition, in order to improve the reflection effect, the first optical structure 41 and the second optical structure 42 can be arranged in multiple rows and columns. Here, the first optical structure 41 and the second optical structure 42 are arranged in two rows. In this application, the distance L2 between the first optical structure 41 and the second optical structure 42 is 4mm. Of course, it can also be arranged in three rows, four rows, etc.

[0045] Of course, referring to Figures 10-11 The first optical structure 41 and the second optical structure 42 can also be arranged in a non-regular hexagonal structure, and can also be arranged in a rhombus, quadrilateral, etc. The reflection path of the light is different according to the different shapes, and different lighting effects can also be formed due to the use of different structural shapes.

In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0047] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited thereto. Within the technical concept of the present application, various simple modifications can be made to the technical solutions of the present application, including that various specific technical features are combined in any suitable manner.
