1. 1 . A vintage car headlight with light emitting diode (LED) light sources, comprising a reflective lamp holder, a heat conducting unit, a low-beam unit, a high-beam unit, a light shading unit, and an optical lampshade; wherein the reflective lamp holder is bowl-shaped and provided with a substantially blind concave installation slot and a light concentrating and reflecting surface formed on an inner surface of the reflective lamp holder; wherein the heat conducting unit is composed of a vertical wall mounted in the installation slot, and an assembly wall disposed at a first end thereof on a surface of the vertical wall and extending away from the installation slot toward a second end thereof; wherein the assembly wall is tapered toward the second end thereof such that an upper surface of the assembly wall is inclined downward toward the second end, and a lower surface of the assembly wall is inclined upward toward the second end; wherein the low-beam unit is disposed on the inclined upper surface of the assembly wall and provided with a low-beam circuit board and at least one low-beam LED light source arranged at the low-beam circuit board; wherein the high-beam unit is disposed on the inclined lower surface of the assembly wall and provided with a high-beam circuit board and at least one high-beam LED light source disposed on the high-beam circuit board; wherein the light shading unit consists of a vertical segment and a horizontal segment; wherein the vertical segment is connected to the second end of the assembly wall; wherein the horizontal segment extends from an upper edge of the vertical segment toward the vertical wall above the inclined upper surface of the assembly wall, the horizontal segment having a curved edge on an end thereof; wherein the optical lampshade is connected to a front end of the reflective lamp holder and provided with an optical diffusion surface, the optical diffusion surface being formed on an inner surface of the optical lampshade and having a plurality of optical diffusion areas; and wherein the optical lampshade is transparent such that a lattice-shaped outline of the optical diffusion areas is visible from an outside of the optical lampshade.
2. 2 . The vintage car headlight with LED light sources as claimed in claim 1 , wherein at least one bump is arranged at a surface of the second end of the assembly wall; and at least one hole is formed on the vertical segment of the light shading unit and configured to mount a corresponding one of the at least one bump to thereby further position the light shading unit on the heat conducting unit.

Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a vintage car headlight with LED light sources, especially to a vintage car headlight which uses light emitting diodes (LED) as light sources of low-beam and high-beam lights and converts light from a point light source into a light surface for compliance with regulatory requirements. A vintage charm is provided due to patterns of optical diffusion areas on an inner surface of a transparent optical lampshade. Description of Related Art A vintage car is not only having a sense of nostalgia and historic meaning, but also showing design concepts, standards of workmanship, and popular culture at that time. That's why the vintage car is valuable. Thus vintage cars are now collectables. Some collectors even restore and keep vintage cars on the road to make the most of them. In early times, light sources of high beams and low beams in headlights are bulbs which are consumables with limited service life. When the bulbs are discontinued, no bulbs with the same specifications can be used for replacement so that users can't drive the vintage car on the road. Once headlights with modern style are used, the new headlights and old-fashioned vintage car don't match with each other. Thus there is room for improvement and there is a need to provide a vintage headlight which is not only compliant with regulatory standards but also matched to the vintage car. SUMMARY OF THE INVENTION Therefore, it is a primary object of the present invention to provide a car headlight which uses light emitting diode (LED) as light sources and offers a vintage charm due to patterns of optical diffusion areas on an inner surface of a transparent optical lampshade. In order to achieve the above object, a vintage car headlight with LED light sources according to the present invention includes a reflective lamp holder, a heat conducting unit, a low-beam unit, a high-beam unit, a light shading unit, and an optical lampshade. The reflective lamp holder is bowl-shaped and provided with a concave installation slot and a light concentrating and reflecting surface formed on an inner surface of the reflective lamp holder. The heat conducting unit is mounted in the installation slot and composed of a vertical wall arranged with respect to the installation slot, and an assembly wall disposed on a surface of one side of the vertical wall and extending toward a direction away from the installation slot. A distance between an upper surface and a lower surface of the assembly wall is tapered from one end close to the vertical wall toward another end away from the vertical wall. Thus the upper surface is inclined downward while the lower surface is inclined upward. The low-beam unit is mounted to the upper surface of the assembly wall and provided with a low-beam circuit board and at least one low-beam LED light source disposed on the low-beam circuit board. The high-beam unit is disposed on the lower surface of the assembly wall and composed of a high-beam circuit board and at least one high-beam LED light source arranged at the high-beam circuit board. The light shading unit is composed of a vertical segment and a horizontal segment. The vertical segment is connected to the end of the assembly wall away from the vertical wall. The horizontal segment is extending from an upper edge of the vertical segment toward the vertical wall and having a curved edge on an end. The optical lampshade is connected to a front end of the reflective lamp holder and provided with an optical diffusion surface which is formed on an inner surface of the optical lampshade and having a plurality of optical diffusion areas. The optical lampshade is transparent so that lattice-shaped outline of the optical diffusion areas can be seen from the outside of the optical lampshade. Preferably, at least one bump is arranged at a surface of the end of the assembly wall away from the vertical wall. At least one hole is formed on the vertical segment of the light shading unit for mounting the bump correspondingly and further positioning the light shading unit on the heat conducting unit.
