[0033] As Figures 1-6 shown, this embodiment provides an optical structure, which further includes a light source module 4. The light source module 4 includes a PCB board 41 and LED light sources 42 arranged on the PCB board 41. Or the light source module 4 includes a light guide and a plurality of LED light sources 42 arranged at intervals on the light guide.

[0034] A light-shielding space is formed between the first light-shielding member 31 and the second light-shielding member 32. The light source module 4 is located in the light-shielding space. The light source module 4 does not contact the light-shielding component 3. The light-shielding component 3 can shield the light source module 4 and the light homogenizing sheet 2, having a good appearance effect.

[0035] The PCB board 41 is in a vertical state, and the LED light sources 42 face the light homogenizing sheet 2. A plurality of LED light sources 42 arranged along its length direction are provided at the center position of the PCB board 41, and the plurality of LED light sources 42 are arranged equidistantly and spaced apart on the same straight line. The emission center line of the LED light sources 42 and the horizontal center line of the light homogenizing sheet 2 are located on the same straight line.

[0036] In this embodiment, the included angle between the emission center line of the LED light sources 42 and the normal line of the light-emitting end face of the thick-wall member 1 is less than 30°. The light emitted by the LED light sources 42 enters the light homogenizing sheet 2 through the incident light end face of the light homogenizing sheet 2. The light homogenizing sheet 2 homogenizes the light, and then the light exits from the exit light end face of the light homogenizing sheet 2, enters the thick-wall member 1 again through the incident light end face of the thick-wall member 1, the light conducts in the thick-wall member 1, and exits from the light-emitting end face of the thick-wall member 1, achieving the effect of light uniformity.

[0037] In this embodiment, the light homogenizing sheet 2 is a rectangular plate-like structure. Among them, the horizontal distance L1 between the incident light end face and the exit light end face of the light homogenizing sheet 2 is 0.5 - 3 mm. Both the incident light end face and the exit light end face of the light homogenizing sheet 2 are flat surfaces and are vertically arranged. The light homogenizing sheet 2 is made of polycarbonate (PC) material or polymethyl methacrylate (PMMA) material. Among them, the light homogenizing sheet 2 is added with an organosilicon light diffusing agent to increase the haze value to achieve the light homogenizing effect. The haze value of the light homogenizing sheet 2 is 7% - 30%, presenting a light-transmitting and opaque effect.

[0038] The incident light end face of the thick-wall member 1 corresponds to and fits with the exit light end face of the light homogenizing sheet 2. The surface of the thick-wall member 1 is flush with the surface of the light homogenizing sheet 2, and the bottom surface of the thick-wall member 1 is flush with the bottom surface of the light homogenizing sheet 2. The incident light end face of the thick-wall member 1 is a flat surface and is vertically arranged; the exit light end face of the thick-wall member 1 is an inclined surface. Among them, the horizontal distance L2 from the surface of the thick-wall member 1 from its incident light end face to its exit light end face is 20 - 180 mm. In this embodiment, the thick-wall member 1 can be a colorless transparent member or a colored transparent member, and is made of polycarbonate (PC) material or polymethyl methacrylate (PMMA) material. The haze value of the thick-wall member 1 is ≤7%, presenting a light-transmitting and transparent effect.

[0039] In this embodiment, by integrally injection-molding the light homogenizing sheet 2 and the thick-walled member 1, the assembly accuracy and efficiency of the light homogenizing sheet 2 and the thick-walled member 1 can be improved, the light output effect of the optical structure can be enhanced. The light can directly enter the thick-walled member 1 through the light homogenizing sheet 2, reducing the loss of light and improving the light output efficiency. By integrally injection-molding the thick-walled member 1 and the light-shielding assembly 3, the first light-shielding member 31 and the second light-shielding member 32 respectively extend to the front of the incident light end face of the light homogenizing sheet 2, which can reduce the space occupation. The overall optical structure connects and assembles the light homogenizing sheet 2, the thick-walled member 1, and the light-shielding assembly 3 by integrally injection-molding, reducing the complexity of assembly, enabling the optical structure to be applied in a narrow space, and achieving the effect of uniformly guiding out the light.

[0040] Embodiment Two

[0041] This embodiment optimizes the optical structure on the basis of the above embodiment, especially providing a specific implementation manner of the light-shielding assembly:

[0042] The above light-shielding assembly 3 includes a first light-shielding member 31 and a second light-shielding member 32. The first light-shielding member 31 is located above the thick-walled member 1, and the second light-shielding member 32 is located below the thick-walled member 1. The first light-shielding member 31 and the second light-shielding member 32 are respectively integrally injection-molded with the thick-walled member 1.

[0043] Figure 1 is one of the structural schematic diagrams of the optical structure provided by the embodiment of the present application; Figure 4 is the light path schematic diagram of the optical structure provided by the embodiment of the present application.

[0044] As Figure 1 、 Figure 4 shown, the structures of the first light-shielding member 31 and the second light-shielding member 32 can be the same or different. In this embodiment, the structures of the first light-shielding member 31 and the second light-shielding member 32 are the same.

[0045] The first light-shielding member 31 includes a light-shielding portion 33, a first bending portion 34 disposed on one side of the light-shielding portion 33, and a second bending portion 35 disposed on the other side of the light-shielding portion 33. An extending end 36 is provided at the end of the second bending portion 35. The light-shielding portion 33, the first bending portion 34, the second bending portion 35, and the extending end 36 are all components with equal thickness, and the thickness H is 2 - 3 mm. Among them, the light-shielding portion 33 is arranged parallel to the thick-walled member 1, and the light-shielding portion 33 has gaps with the thick-walled member 1 and the light homogenizing sheet 2 respectively.

[0046] The end of the first bending portion 34 is integrally injection-molded and connected to the thick-walled member 1, and the first bending portion 34 extends outwardly and expands from the thick-walled member 1. The second bending portion 35 extends outwardly and expands relative to the light homogenizing sheet 2. The extending end 36 is arranged parallel to the thick-walled member 1 and is located on the side of the PCB board 41, and the extending end 36 is spaced apart from the PCB board 41.

[0047] A shielding space is formed between the first light-shielding member 31 and the second light-shielding member 32. Specifically, the second bending portion 35 located above and below the light source module 4 can function to shield the light source module 4. The light emitted by the light source module 4 is reflected by the second bending portion 35. The light-shielding component 3 can block the connection between the light homogenizing sheet 2 and the thick-walled member 1, so that the internal components of the shielding space cannot be seen from the outside of the light-shielding component 3, showing a better appearance.
