Description

Technical Field

[0001] This utility model belongs to the field of automotive headlight technology, and particularly relates to an automotive headlight assembly with good uniformity. Background Technology

[0002] Automotive lights are lighting devices installed at the front of a car for illumination, warning, and signal transmission. They play a vital role in driving safety. With the development of the automotive industry and technological progress, the functions and effects of automotive lights have also changed along with technological iterations.

[0003] Currently, most automotive headlights use transparent, thick-walled components to improve beam uniformity, resulting in a softer beam and better display. However, the limited internal space and design constraints of existing automotive headlights mean that most applications employ single-layer thick-walled components to enhance beam uniformity. However, the improvement in beam uniformity from a single-layer thick-walled structure is limited, thus failing to achieve a truly uniform beam. Utility Model Content

[0025] The lamp cover 11 and the lamp housing body 12 for supporting the lamp cover 11 are provided. The lamp housing body 12 is disposed in the front cavity for arranging the car lamp assembly. The lamp housing body 12 has a device cavity inside for accommodating different combinations of light sources.

[0026] An optical module 20 for positioning / daytime travel / turning functions is designed as a ring and arranged inside the device cavity. The optical module 20 includes an outer decorative frame 21 and an inner decorative frame 22. A light source module 30 is provided on the inner decorative frame 22. An outer transparent thick-walled component 23 is provided on the outer decorative frame 21. An inner transparent thick-walled component 24 is also provided between the outer transparent thick-walled component 23 and the light source module 30. The light beam emitted by the light source module 30 passes through the inner transparent thick-walled component 24 and then passes through the outer transparent thick-walled component 23 again. After the light beam undergoes secondary processing, it leaves the outer transparent thick-walled component 23 and diffuses outward from the outer lamp cover 11. The light source module 30 is configured with corresponding light sources according to the positioning / daytime travel / turning functions.

[0027] In this embodiment, the light beam emitted by the light source module 30 is processed by a double-layer thick-walled component. A cavity is constructed inside the optical module 20, and the outer transparent thick-walled component 23 and the inner transparent thick-walled component 24 are respectively set in the cavity and the port between the optical module 20 and the outside. The inner transparent thick-walled component 24 is used to supplement the outer transparent thick-walled component 23. The double-layer design avoids the problem of insufficient light processing effect of a single thick-walled component. The uniformity of the light beam is greatly improved under the double-layer design.

[0028] In a preferred embodiment of this invention, the outer decorative frame 21 is provided with a slot for accommodating the outer transparent thick-walled member 23.

The end face of the outer transparent thick-walled member 23 facing the outer lampshade 11 is the second light-emitting surface 201, which faces the outer lampshade 11 through the slot. The end face of the outer transparent thick-walled member 23 away from the second light-emitting surface 201 is the second light-incident surface 202, which is located on the side adjacent to the inner transparent thick-walled member 24.

[0030] In this embodiment, the light beam emitted by the light source module 30 enters the inner transparent thick-walled member 24 from the first light-incident surface 204 and then exits from the first light-exiting surface 203. It then enters the outer transparent thick-walled member 23 from the second light-incident surface 202 and then leaves the optical module 20 from the second light-exiting surface 201 of the outer transparent thick-walled member 23. Finally, it enters the lamp housing body 12 and is emitted outward through the outer lamp cover 11.

[0031] As a preferred embodiment of this example, a focusing groove is provided at the first light-incident surface 204, the light source module 30 faces the focusing groove, and the light beam emitted by the light source module 30 diffuses into the interior of the transparent thick-walled member 24 through the focusing groove.

[0032] In a preferred embodiment of this invention, the second light-incident surface 202 and the first light-exiting surface 203 are spaced apart; the second light-incident surface 202 and the first light-exiting surface 203 are arranged in parallel to form a spaced region, and the light beam enters the outer transparent thick-walled member 23 again through the spaced region.
