[0029] A headlight structure having a headlight pattern structure 4 includes a light source 1, a thick-walled member 2, and a concentrator 3 disposed between the thick-walled member 2 and the light source 1. The headlight pattern structure 4 is disposed on the thick-walled member 2 and on at least one of the sidewalls of the thick-walled member 2 facing away from the concentrator 3 and the sidewall of the thick-walled member 2 facing closer to the concentrator 3. The headlight pattern structure 4 can be integrally formed onto the outer or inner surface of the thick-walled member 2 through an injection molding process, or can be applied to the outer lampshade / bezel through processes such as hot stamping or laser engraving.

[0030] The headlight light distribution pattern structure 4 includes a plurality of pattern units 5, which are arranged in a regular array. The size, relative position, angle, and number of pattern units 5 can be adjusted according to specific needs, or randomly arranged.

[0031] Each pattern unit 5 includes a first light distribution unit 6, a second light distribution unit 7 and a third light distribution unit 8. The first light distribution unit 6, the second light distribution unit 7 and the third light distribution unit 8 share a vertex P. Adjacent light distribution units have a common boundary line, which is L1, L2 and L3.

[0032] Taking the plane where the edge of the pattern unit 5 is located as the reference plane, the projections of the first light distribution unit 6, the second light distribution unit 7 and the third light distribution unit 8 on the reference plane are all quadrilaterals. The projection of the pattern unit 5 formed by the interconnection of the first light distribution unit 6, the second light distribution unit 7 and the third light distribution unit 8 on the reference plane is a triangle, which is preferably an equilateral triangle.

[0033] The light distribution pattern can be arranged in a non-diffused, curved, or be in the form of a beveled polyhedron diamond, depending on the specific application needs. Specifically, the first light distribution unit 6, the second light distribution unit 7, and the third light distribution unit 8 can be located in the same plane, and there can also be an angle between adjacent light distribution units. When there is an angle between adjacent light distribution units, the angles between adjacent light distribution units are the same and range from 45 to 180 degrees. The end of the common point of the first light distribution unit 6, the second light distribution unit 7, and the third light distribution unit 8 protrudes toward the concentrator 3 or protrudes away from the concentrator 3.

[0034] The concentrator 3 collimates the light emitted by the light source 1 and transmits the collimated light toward the thick-walled part 2. The light is refracted by the headlight light distribution pattern structure 4 and then emitted. The light refracted by the headlight light distribution pattern structure 4 is evenly and regularly distributed. The lighting effect breaks through the traditional rectangular pattern form and has a unique and beautiful lighting effect.

[0035] The structure of the present invention can be used in conjunction with other structures in a vehicle lamp, and the light hitting the inner side of the system is not limited to the collimated light from the reflector, condenser 3, etc., but can also be non-collimated light, such as light from scattering materials.

[0036] Based on the above-described preferred embodiments of the present invention, and in accordance with the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
