[0028] Example 1:
[0029] like Figures 1 to 3 As shown, a light distribution pattern structure includes: a pattern group 1, the pattern group 1 including a plurality of first pattern units 2 and a plurality of second pattern units 3, the second pattern units 3 being connected to the first pattern units 2.
[0030] The projection of the first pattern unit 2 onto the horizontal plane is hexagonal. The sidewall of the first pattern unit 2 has six sides, which are either planar or curved. The first pattern unit 2 is provided with a first light distribution pattern 21, which is used for light refraction. The first light distribution pattern 21 is provided on each of the six sides of the first pattern unit 2. The first light distribution pattern 21 is triangular or quadrilateral, and is either planar or curved. The first light distribution pattern 21 is either concave or convex.
[0031] The first light distribution pattern 21 is inclined and there are multiple first light distribution patterns 21. The sidewalls of adjacent first light distribution patterns 21 are connected to each other, and the six first light distribution patterns 21 form a hexagonal pyramid or hexagonal frustum structure. The top or bottom of the multiple first light distribution patterns 21 extend to the middle of the first pattern unit 2 and connect, that is, the first pattern unit 2 is raised upward or recessed downward.
[0032] The projection of the second pattern unit 3 onto the horizontal plane is a pentagon. The sidewall of the second pattern unit 3 has five sides, which are either planar or curved. The second pattern unit 3 is provided with a second light distribution pattern 31, which is used for light refraction. The second light distribution pattern 31 is provided on each of the five sides of the second pattern unit 3. The second light distribution pattern 31 is triangular or quadrilateral, and is either planar or curved. The second light distribution pattern 31 is either a concave pattern or a convex pattern.
[0033] The second light distribution pattern 31 is inclined and there are multiple second light distribution patterns 31. The sidewalls of adjacent second light distribution patterns 31 are connected to each other, and five second light distribution patterns 31 form a pentagonal pyramid or pentagonal frustum structure. The top or bottom of multiple second light distribution patterns 31 extend to the middle of the second pattern unit 3 and connect, that is, the second pattern unit 3 is raised upward or recessed downward.
[0034] In this embodiment, the end of the first light distribution pattern 21 is connected to the end of the second light distribution pattern 31, and the side lengths of the first pattern unit 2 and the second pattern unit 3 are equal and fit together; after the light shines on the first light distribution pattern 21 and the second light distribution pattern 31, it is refracted to form patterns with hexagonal and pentagonal bases respectively, so that the light-emitting surface is a shape of pentagon and hexagon connected together, and the lighting effect is unique and beautiful.
[0035] Example 2:
[0036] like Figure 1 As shown, based on Embodiment 1, multiple pattern groups 1 are provided, and the multiple pattern groups 1 are arranged in a horizontal array. The multiple pattern groups 1 are connected to form a pattern structure 4. The first pattern units 2 of adjacent pattern groups 1 are connected; the second pattern units 3 of adjacent pattern groups 1 are connected; the first pattern unit 2 and the second pattern unit 3 of adjacent pattern groups 1 are connected. The multiple pattern groups 1 are arrayed and connected in different ways as needed to form a unique and beautiful structure, which makes the light emission and lighting effect good.
[0037] Example 3:
[0038] like Figure 3 As shown, based on Embodiment 2, a vehicle light includes: a patterned structure 4 and a thick-walled component 5. A concentrator 51 is provided at the end of the thick-walled component 5. The concentrator 51 is used to focus light into the thick-walled component 5. By placing an LED light at the concentrator 51, the light emitted by the LED light is focused into parallel light by the concentrator 51 and enters the thick-walled component 5. The patterned structure 4 is located at the end of the thick-walled component 51 away from the concentrator 52. The patterned structure 4 is used to emit light evenly. The light passes through the thick-walled component 5 and hits the patterned structure 4. The light is refracted on the patterned structure 4 to form a light-emitting surface shape with a base of pentagons and hexagons connected to each other before being emitted. The light emission effect is good and the light emission shape is unique, realizing the interaction between the inside of the vehicle and the outside world.
[0039] In summary, the light emitted by the light source is focused into parallel light by the concentrator 51 and enters the thick-walled component 5. The light then shines on the patterned structure 4 through the thick-walled component 5. After being refracted on the first light distribution pattern 21 of the first patterned unit 2 and the second light distribution pattern 31 of the second patterned unit 3, the light exits the thick-walled component 5. After being refracted on the first patterned unit 2, the light forms a light surface with a hexagonal base. After being refracted on the second patterned unit 3, the light forms a light surface with a pentagonal base. The exit surface has a unique shape with an array of interconnected pentagons and hexagons, resulting in a beautiful and unique lighting effect that enables interaction between the vehicle interior and the outside world.
