Detailed Description

FIG. 2 is a cross-sectional view of a lamp assembly in a first position according to one embodiment of the present invention. As shown in FIG. 1, in one embodiment, a vehicle lamp assembly includes an LED light source 10, a reflector 20, and a light diffusing interior mirror 30. The light beam emitted from the LED light source 10 directly irradiates the reflector 20, is reflected by the reflector 20, irradiates the light-diffusing internal lens 30, and is diffused by the light-diffusing internal lens 30 and then is emitted. When the vehicle lamp is a back door through lamp of a vehicle, as shown in fig. 1, the LED light source 10 emits a light beam downward, the reflector 20 is located below the LED light source 10, and the working surface of the light diffusing inner lens 30 (i.e., the surface through which the light beam passes) is disposed behind the reflector 20.

In the embodiment, the reflector 20 is additionally arranged at the downstream of the light beam emitted by the LED light source 10, so that the distance from the LED light source 10 to the light outlet can be increased, and therefore, the position lamp can uniformly emit light under the limited car lamp arrangement space, and the effects of light running and the like are achieved. For the back door through lamp of the vehicle, the arrangement mode can save the X-direction size, so that the lamp can be ensured to uniformly emit light under the condition of limited space size.

Fig. 3 is a schematic structural view of the LED light source 10 and the reflector 20 of the lamp assembly according to one embodiment of the present invention. As shown in fig. 3, in one embodiment, the surface of the reflector 20 is provided with a concave-convex optical pattern 21 to scatter and reflect the light beam of the LED light source 10. The optical pattern 21 may be in the form of a corn-like pattern, each pattern being sized and shaped to reflect light at an angle that is tailored to provide for the distributed emission of light from the LED light source 10.

In a further embodiment, the surface of the optical pattern 21 is a rough surface, for example, a frosted surface, to provide diffuse reflection of the light beam. The diffusely reflected light is diffusely emitted by the light diffusing inner mirror 30, where the light passing surface of the light diffusing inner mirror 30 needs to be smaller in the Z-direction dimension of the vehicle, i.e. in the vertical direction in fig. 2, than the Z-direction dimension of the reflective working surface of the mirror 20.

As shown in fig. 2, in the present embodiment, the reflector 20 is disposed downstream of the light beam emitted from the LED light source 10, the reflector 20 is arc-shaped, and the light diffusing internal mirror 30 is disposed downstream of the light beam reflected by the reflector 20. Further, the LED light source 10 may be arranged horizontally, which emits a light beam downward, and the concave surface of the reflector 20, which faces the LED light source 10 and the light diffusing internal lens 30, is provided with an optical pattern 21.

In another embodiment, the lamp assembly further includes a trim bezel 40 that is an integrally molded part with the light diffusing interior lens 30, such as by two-shot molding. The LED light source 10 is fixedly mounted at the bezel 40 or the light diffusing inner lens 30. This ensures that the LED light source 10 and the reflector 20 are relatively immovable in position to ensure optical effects.

As shown in fig. 2, the lamp assembly further includes a bottom shell 50 and a cover 60, which are fixedly assembled, wherein the bottom shell 50 and the cover 60 together form a receiving space for receiving the LED light source 10, the reflector 20, the light diffusing inner lens 30 and the decorative frame 40.

FIG. 4 is a cross-sectional view of a lamp assembly in a second position in accordance with one embodiment of the present invention. In one embodiment, the light diffusing inner lens 30 is fixedly mounted at the decoration frame 40, as shown in fig. 4, in one embodiment, the light diffusing inner lens 30 is formed with a first mounting portion 31, the first mounting portion 31 is provided with a first threaded hole 311, the reflector 20 is provided with a portion overlapping with the first mounting portion 31, the portion is provided with a first mounting hole 201 aligned with the first threaded hole 311, and the light diffusing inner lens 30 and the reflector 20 can be fixedly connected by screwing a screw through the first mounting hole 201 and then screwing the screw with the first threaded hole 311.

Further, the light diffusing inner lens 30 is fixedly mounted at the bottom case 50. As shown in fig. 2, the light diffusing inner lens 30 is provided with a second mounting portion 32, the second mounting portion 32 is provided with a second threaded hole 321, the bottom shell 50 abuts against the second mounting portion 32 and is provided with a second mounting hole 501, and the light diffusing inner lens 30 and the bottom shell 50 can be fixedly connected by screwing the screw through the second mounting hole 501 and then screwing the screw with the second threaded hole 321. This ensures that the light diffusing internal lens 30 and the reflector 20 are integrally fixed to the bottom case 50, and the relative positions are not changed.

The utility model also provides a vehicle comprising the lamp assembly in any one or combination of the above embodiments.

According to the position lamp of the vehicle, the reflector 20 is additionally arranged at the downstream of the light beam emitted by the LED light source 10, so that the distance from the LED light source 10 to the light outlet can be increased, the position lamp can be guaranteed to uniformly emit light under the limited vehicle lamp arrangement space, and the effects of light flowing and the like are achieved. For the back door through lamp of the vehicle, the arrangement mode can save the X-direction size, so that the lamp can be ensured to uniformly emit light under the condition of limited space size.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model.
