Detailed Description

In order to make those skilled in the art fully understand the technical solutions and advantages of the present invention, the following description is further provided with reference to specific embodiments.

A daytime running/position lamp as shown in fig. 1-4 mainly comprises an outer lens 1, a radium carving ring 2, a thick wall 3, a thick wall bracket 4, a bottom decorating ring 5, a PCBA circuit board 6 and a shell 7, wherein the connection relationship of all parts is as follows: thick wall support 4 is the assembly main part, and PCBA circuit board 6 passes through the fix with screw with thick wall support 4, and thick wall 3 passes through the fix with screw with thick wall support 4, and radium carving decorative ring 2 passes through screw and bayonet lock with thick wall support 4 to be fixed, and thick wall support 4 passes through the fix with screw with casing 7, and bottom decorative ring 5 passes through the fix with screw with casing 7, and casing 7 is fixed and is sealed through sealed glue with outer lens 1, accomplishes the assembly of whole car light from this.

The laser carving decoration ring 2 is a transparent plastic piece integrally formed by a mould, a shading coating (opaque black paint) is sprayed on the outer surface of the laser carving decoration ring, and after the spraying, transparent patterns 2-1 are laser carved on the shading coating by using laser. The thick wall 3 is also an L-shaped transparent plastic part, one end of the thick wall is right opposite to the LED light source on the PCBA circuit board 6, and the other end of the thick wall is positioned below the laser engraving decorative ring 2. The outer surface of the corner of the thick wall is provided with a 45-degree reflecting surface, the front end surface of the thick wall is provided with a thick-wall front light-emitting surface 3-2 (namely a light-emitting surface a) with optical patterns, and the upper side surface of the thick wall is provided with a thick-wall upper light-emitting surface 3-1 (namely a light-emitting surface b) with frosted dermatoglyph. The outer lens 1 is made of transparent material, which mainly plays a role of protection, so that no optical pattern is arranged on the inner surface and the outer surface of the outer lens. Other parts such as the thick-wall bracket 4, the bottom decorative ring 5, the shell 7 and the like are all lightproof plastic pieces and mainly play roles in connection, support, fixation and the like.

In the utility model discloses in each scheme before, the light that the LED light source on PCBA circuit board 6 sent reflects the back through the optical reflection face of thick wall 3, directly passes the thick wall before go out plain noodles 3-2 and jet out through outer lens 1 (as the light path of horizontal direction in fig. 3), and another part light goes out plain noodles 3-1 refraction to the decorations circle on the thick wall, and this part light has not obtained effective utilization, very big influence the effect of lighting.

In order to solve the problem, the inventor team optimizes and redesigns the decorative ring on the upper side of the thick wall, a laser engraved pattern surface is additionally arranged on the new laser engraved decorative ring 2, and refracted light which should be emitted to a non-transparent area of the upper decorative ring passes through a transparent pattern 2-1 of the laser engraved decorative ring 2 and finally passes through the outer lens 1 to form a unique sun/position light starry sky lighting effect. The improved daytime running/position lamp not only meets the optical function regulation requirements, but also ensures the unique appearance design requirements of customers, and has lower cost. The lighting effect of the car lamp is richer, more diversified and more beautiful, the higher identification degree and the higher technological sense are shown, and better economic benefit can be generated after a new car is listed.
