DETAILED DESCRIPTION

[0016] The implementation and usage of specific embodiments are discussed in detail below. However, it should be understood that the discussed specific embodiments are merely intended to illustrate specific ways of implementing and using the present disclosure, and are not intended to limit the scope of the present disclosure.

[0017] In this specification, directional expressions such as "upper", "lower", "left", "right", "front" and "back" and the like are not absolute but are relative when describing the structural positions of various components. When the components are arranged as shown in the figures, these directional expressions are appropriate, but when the positions of the components in the figures are changed, these directional expressions should be changed accordingly.

[0018] In this specification and the accompanying drawings, the X direction represents a longitudinal direction of the vehicle (that is, a front-rear direction indicating a traveling direction of the vehicle), the Y direction represents a transverse direction of the vehicle (that is, a left-right direction perpendicular to the front-rear direction in a plane parallel to the ground), and the Z direction represents a vertical direction of the vehicle (that is, an up-down direction perpendicular to the ground).

[0019] A preferred embodiment of the present disclosure is described below with reference to FIGS. 1 to 5.

[0020] As shown in FIG. 1 to FIG. 3, the vehicle light assembly A according to the present disclosure is, for example, a vehicle light assembly provided above a front bumper of a vehicle for improving aesthetics, uniqueness and recognition of a front portion of the vehicle, which comprises a housing 20 on a rear side and a lens 10 on a front side, and the lens 10 is fixedly connected to the housing 20 to collectively delimit a cavity 30 for accommodating a light-emitting assembly 40.

[0021] More specifically, the lens 10 comprises a transparent cover 15 on the outer side and a black light shield 12 provided on the inner side of the transparent cover 15, the light shield 12 shields a portion of the transparent cover 15, and the front portion (i.e., the front light exiting wall 11) and a part of the upper portion of the transparent cover 15 that are not shielded by the light shield can emit light, that is, form a transparent wall through which light can pass. The front edge portion 21 of the housing 20 is provided with a slot for receiving and fixing the rear edge 13 of the light shield 12, and the slot is filled with glue.

[0022] The light-emitting assembly 40 is provided in the cavity 30 and comprises a light source 41, a supporting member 43 and a light guiding member 42. More specifically, the circuit board 411 is provided at the rear of the cavity 30, and the light source 41 is provided as a light-emitting element 412, such as an LED lamp bead, provided on the circuit board 411. The rear portion of the supporting member 43 is fixedly connected to the housing 20 along the X-direction by a screw 53. The light guiding member 42 is supported on the supporting member 43, a rear end portion of the light guiding member 42 comprises a light inlet surface 423 located below the light source 41 to receive light emitted by the light source 41, and a front end portion of the light guiding member 42 comprises a flat light exiting surface 421 facing the light exiting wall 11 of the transparent lens 10, and an optical protrusion 422 protruding towards the light exiting wall 11 relative to the light exiting surface 421. The arrows in Fig. 3 indicate the transmission path of the light within the light guiding member 42.

[0023] As shown in FIG. 4, the light exiting surface 421 has a first optical pattern 4211, such that the light emitted via the light exiting surface 421 has a substantially uniform overall brightness. The optical protrusion 422 has a second optical pattern 4221 different from the first optical pattern 4211, such as a dense wavy or zigzag pattern. When the light reaches the optical protrusion 422, due to its special geometric shape, the first light emitted via the optical protrusion 422 towards the lens 10 is more concentrated than the second light emitted via the light exiting surface 421 towards the lens 10, thereby achieving a higher brightness. As shown by the arrow directions F1 and F2 in FIG. 4, the first optical pattern 4211, for example, is provided to guide light to emit forward mainly along the X direction, and the second optical pattern 4221, for example, is provided to guide light to emit mainly towards a side portion of the vehicle, such that the optical protrusion 422 is brighter when observed from the lateral side to enhance the visual effect.

[0024] In the illustrated embodiment, the optical protrusion 422 is provided as an elongated rib extending along a lower edge of the light exiting surface 421. According to a variant, the elongated rib may also be provided at other edge position or a central area of the light exiting surface 421. According to another variant, the number of the elongated rib may be multiple, forming parallel or staggered arrangement, and the spacing between the ribs may be adjusted as needed to control the light diffusion. According to another variant, the shape of the optical protrusion 422 may also be curved or wavy, and the width and protruding height of the optical protrusion 422 may be set according to actual needs to create a layered light effect and enhance the visual attraction and personalized features.

[0025] In the illustrated embodiment, the supporting member 43 comprises an end portion 432 protruding towards the light exiting wall 11 relative to the light exiting surface 421, and the end portion 432 comprising a reflecting surface 4321, and the reflecting surface 4321 is provided to face the light exiting wall 11 of the lens 10 and is inclined relative to the light exiting surface 421. As shown in FIG. 5, a part of the light emitted from the light guiding member 42 will be reflected by the lens 10 to the reflecting surface 4321, and then emitted from the transparent lens 10 after being reflected by the reflecting surface 4321, which can visually increase the light exiting area, such that more light from the light source 41 can be emitted by passing through the lens 10, thereby improving the overall luminous brightness of the vehicle light assembly A. According to the illustrated embodiment, the light exiting surface 421 and the reflecting surface 4321 are respectively provided on two opposite sides, for example, upper and lower sides of the optical protrusion 422, such that the optical protrusion 422 forms a bright line at an approximate middle position of the vehicle light, thereby improving the overall aesthetics of the vehicle light assembly A.

[0026] In the illustrated embodiment, the reflecting surface 4321 is provided as a plane, and the angle between the reflecting surface 4321 and the light exiting surface 421 may be provided between 130 degrees and 140 degrees, such as about 135 degrees. According to another variant, the reflecting surface 4321 may also be provided as a convex curved surface or a concave curved surface. The concave curved surface can converge light, so as to form a stronger light intensity in a specific area as needed; the convex curved surface can spread light more widely and cover a larger area. Preferably, the reflecting surface 4321 has a white color. It can be understood that the reflecting surface 4321 may also be set to have other light colors. Light colored surfaces can reflect more light than dark colored surfaces, thereby creating a bright effect.

[0027] The technical contents and features of the present disclosure have been disclosed above. However, it is conceivable that, those skilled in the art can make various changes and improvements to the above concept under the creative idea of the present disclosure, all of which fall within the protection scope of the present disclosure.
