Example 1
Referring to fig. 1 and 2, a thick-wall light guiding structure with zoned illumination is provided in the present embodiment. It comprises a thick-walled light guide 1, a reflective member 2, an LED light source assembly 3 and two light shields 4. Wherein the LED light source assembly 3 includes a PCB board 31 and LEDs 32 mounted on the PCB board 31. The positional relationship is as follows: the LED light source assembly 3 is disposed over the rear of the thick-walled light guide 1, the reflective member 2 is disposed behind the thick-walled light guide 1, and the pcb board 31 is disposed over the reflective member 2. A first pattern 11 and a second pattern 12 are provided on the light exit surface of the thick-wall light guide 1. The first patterns 11 are diffusion patterns, so that light rays are diffused out through the first patterns 11 after entering the thick-wall light guide 1, and are displayed as bright areas; the second pattern 12 is designed such that the incident angle α is larger than the critical angle of the thick-walled light guide 1, so that the light ray is totally reflected by the second pattern 12 after being incident on the thick-walled light guide 1, and is displayed as a dark area.
Referring to fig. 3 to 5, in the present embodiment, when the second pattern 12 is a pyramid pattern. Of course, the shape of the second pattern 12 may be designed according to practical situations, and is not limited thereto. The principle of realizing the bright-dark division will be described below, and the light emitted from the LED32 on the PCB board 31 is horizontally incident into the thick-wall light guide 1 through the reflecting member 2, and is diffused out after passing through the diffusion pattern on the light-emitting surface of the thick-wall light guide 1. I.e. the visually corresponding areas are bright areas. When light emitted from the LED32 on the PCB board 31 is horizontally injected into the thick-walled light guide 1 through the reflecting member 2, the light passes through the pyramid pattern on the light-emitting surface of the thick-walled light guide 1. The angle between the horizontal ray and all faces of the pyramid pattern, i.e. the angle of incidence α, is 45 ° greater than the critical angle 42 ° of the thick-walled light guide 1. The light rays are totally reflected in the pyramid pattern, so that no light is emitted on the surface of the pyramid pattern, i.e. the visually corresponding area is a dark area. Here, the thick-wall light guide 1 is made of an optical transparent PC material by injection molding. In an embodiment, the thick-wall light guide 1 may also be made of PMMA. The direction of the arrow in the figure is the direction of propagation of the light.
In the present embodiment, the positions of the first pattern 11 and the second pattern 12 may be arranged according to the specific case. The arrangement positions of the first pattern 11 and the second pattern 12 are set according to the partition position requirements of the dark area and the bright area. With continued reference to fig. 2, in the present embodiment, the light-emitting surface of the thick-wall light guide 1 sequentially shows the condition of alternating brightness from left to right, and thus the first pattern 11 and the second pattern 12 are sequentially alternately arranged from left to right. When the number is required to be displayed, the first pattern 11 is designed in a portion where the number is highlighted on the light exit surface of the thick-wall light guide 1, and the second pattern 12 is designed in other portions. Specific other design positions will not be described in detail.
In the present embodiment, two light shielding plates 4 are provided on the upper and lower side surfaces of the thick-wall light guide 1, respectively. Specifically, the two light shielding plates 4 can be fastened to the upper and lower side surfaces of the thick-wall light guide 1 by means of clamping. The purpose is to shield stray light, thereby realizing a clear lighting effect of the subareas. The two light shields 4 can be designed according to specific requirements.
In this embodiment, the thick-wall light guide 1 and the PCB board 31 are fixedly connected with the reflective member 2 by at least one of a buckle, a positioning pin, or a bolt. Of course, other means of fixedly attaching may be employed.
In this embodiment, the reflecting member 2 is a reflecting bowl.
In this embodiment, the PCB 31 is a strip-shaped factor circuit board, and the hard circuit board has the advantages of low price, no need of a separate heat dissipation structure, and good light stability emitted by the LED light source.
To sum up: according to the utility model, two different patterns are arranged on the light-emitting surface of the thick-wall light guide 1, light rays emitted by the LED light source assembly 3 are horizontally emitted into the thick-wall light guide through the reflecting component 2, and the light rays are diffused out through the first patterns 11 on the light-emitting surface of the thick-wall light guide 1 to be displayed as a bright area. Since the second pattern 12 is designed such that the incident angle α is larger than the critical angle of the thick-walled light guide, total reflection occurs when light is incident on the second pattern 12 of the light-emitting surface of the thick-walled light guide 1, so that it is displayed as a dark area. Therefore, the effect of realizing clear lighting of the lamp subareas by arranging different patterns can be realized. The shape of the second pattern 12 may be designed as desired by the designer, and the positions of the first pattern 11 and the second pattern 12 may be designed as desired on the light exit surface of the thick-wall light guide. Therefore, the utility model has the advantages of low cost, simple structure and free modeling design on the basis of realizing the partition lighting effect.
