[0007] Further, at the position of the light distribution lens 1 opposite to the light guide bar 4, a thick wall structure is formed by bulging towards both the inside and the outside at the same time. Reflection patterns which are the same or different are arranged on the end faces of the thick wall structure, and decorative leather grains 12 are arranged on the outer surface of the light distribution lens 1 except the thick wall structure.

[0008] Further, the LED module 5 is fixedly arranged perpendicular to the light guide bar 4 on the light guide bracket 9, and at least one LED light source is arranged at the position of the LED module 5 opposite to the light guide bar 4.

[0009] Further, the decorative lamp further includes a light guide light-shielding cover 3. The light guide light-shielding cover 3 is fixed on the light guide bar 4 and opposite to the LED module 5. The function of the light guide light-shielding cover is to block the stray light at the end of the light guide.

[0010] Furthermore, the decorative lamp also includes a wiring harness assembly 6 and a ventilation assembly 7 . The wiring harness assembly 6 is connected to the LED module 5 , and the ventilation assembly 7 is fixed on the lamp housing 2 .

[0011] Furthermore, the appearances of the light distribution lens 1, the lamp housing 2, and the light guide bracket 9 are all trapezoidal, preferably right-angled trapezoidal.

[0012] The utility model also provides a car equipped with the above-mentioned front decorative lights, wherein the front decorative lights are symmetrically distributed on the front of the car or on the left and right sides of the car body.

[0013] The utility model adopts a light distribution mirror + thick wall integrated structure, and realizes a crystal clear appearance through multiple side-by-side light guide strips. After lighting, it presents a snow-white, clean and bright shape. The light distribution mirror is made of CM205 colorless and transparent PMMA material. The LED light source produces a uniform light effect through the light guide strip and the thick wall structure on the light distribution mirror, avoiding the granularity produced by the thick wall in the traditional solution, and further highlighting the whiteness of the light distribution mirror. In addition, a three-dimensional and cool lighting effect is created through the vertical and horizontal interlacing of the light guide structure and the thin strips of decorative leather on the thick wall side wall. The front decorative lamp of the car has the advantages of simple structure, low production and use costs, etc., can bring unique lighting effects and better user experience, and has strong market competitiveness.

DETAILED DESCRIPTION

[0021] To enable those of ordinary skill in the art to fully understand the technical solutions and beneficial effects of the present utility model, the following further description is provided in conjunction with specific embodiments and the accompanying drawings.

[0022] As Figures 1-6 shown, a front decorative lamp for an automobile with a welcome lighting function, which uses an LED as a light source and can be lit when the vehicle is unlocked / locked and not lit when the vehicle is started / driving, thereby presenting a unique welcome lighting effect and function.

[0023] The front decorative lamp for the automobile mainly consists of a light distribution mirror 1, a lamp housing 2, a light guide light-shielding cover 3, a light guide bar 4, an LED module 5, a wire harness assembly 6, a ventilation assembly 7, a light guide bracket 9, etc. The assembly method is as follows: First, fix 3 light guide light-shielding covers 3 one by one on 3 light guide bars 4 through snap fasteners, then align one end of these light guide bars 4 and fix them side by side vertically in the groove of the light guide bracket 9, then use a screw 8 to fix the LED module 5 longitudinally to the light guide bracket 9, and the LED module 5 is installed opposite to the end of the light guide bar 4 with the light guide light-shielding cover 3. Use a screw 8 to fix the assembled light guide assembly as a whole to the lamp housing 2, insert and connect the wire harness assembly 6 with the LED module 5 and then pass it through the lamp housing 2, then fix the ventilation assembly 7 on the lamp housing 2, and finally weld and seal the light distribution mirror 1 and the lamp housing 2 together by hot plate welding, thus completing the general assembly of the lamp.

[0024] The front of the front decorative lamp for the automobile with a welcome lighting function is as Figure 2 shown, including three nearly parallel light-emitting areas from top to bottom. The left or right end of each light-emitting area is aligned, and the other end becomes longer in turn from top to bottom. After being lit, it presents a three-dimensional light-emitting effect of multiple rows and columns, which is very cool and eye-catching.

[0025] To achieve this effect, the light distribution mirror 1 is specially designed: as Figures 3-5 shown, at the position of the light distribution mirror 1 opposite to the light guide bar 4, it bulges both inside and outside to form a thick-wall structure. The length and width of these inner and outer bulges are similar to the size of the corresponding light guide bar 4, and the same or different reflection patterns 10 and 11 are provided on the end faces of these inner and outer bulges, and a decorative leather pattern 12 is also provided around the outer bulge. The thick-wall function is realized through these inner and outer bulges on the light distribution mirror 1, and a better lighting effect can be obtained in cooperation with the light guide bar.
