Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides the following technical solutions: an LED car light structure with a transparent thick-walled part comprises an outer shell 1, an outer lens 2, a PCB 6 and an LED lamp body 7 arranged on the PCB 6, wherein the outer lens 2 is arranged at the end part of the outer shell 1, the LED car light structure also comprises a transparent plastic thick-walled part 3 and an inner lens 8, the transparent plastic thick-walled part 3 is arranged in the outer shell 1, the inner lens 8 is arranged at one end of the outer shell 1 close to the outer lens 2, a condenser 4 is arranged at the position of the surface of the transparent plastic thick-walled part 3 corresponding to the LED lamp body 7, a reflecting inclined plane 5 is arranged at one end surface of the transparent plastic thick-walled part 3 close to the LED lamp body 7, an optical pattern is arranged on one end surface of the transparent plastic thick-walled part 3 facing the inner lens 8, the inclined plane angle of the reflecting inclined plane 5 is 45 degrees, one end surface of the transparent plastic thick-walled part 3 facing the inner lens 8 is an outward convex cambered surface, one end surface of the inner lens 8 facing the transparent plastic thick-walled part 3 is a thick cambered surface, the inner fitting 8 is a convex cambered surface facing the end surface of the outer lens 2, when the LED light source is used, the LED light is diffused by the LED lamp body 7, the diffused LED light is polymerized by the condenser 4 and then controlled in a certain direction, the light collected by the condenser 4 is uniformly reflected in the transparent plastic thick-wall part 3 through the 45-degree reflection inclined surface 5, the optical patterns on the convex cambered surface of the transparent plastic thick-wall part 3 can enable the light to be relatively uniformly projected from the transparent plastic thick-wall part 3 and then reach the inner fitting 8, and the inner fitting 8 is a concave cambered surface facing the end surface of the transparent plastic thick-wall part 3, and the inner fitting 8 is a convex cambered surface facing the end surface of the outer lens 2, so that the light can be more uniformly projected.
