In order to make the technical scheme and the beneficial effects of the present utility model fully understood by those skilled in the art, the following description is further made with reference to specific embodiments and drawings.

The full-LED combined tail lamp as shown in fig. 1-7 comprises two position lamps 10, a turn signal lamp 11, a reversing lamp 12 and a fog lamp 13, wherein the reversing lamp 12 is positioned in the middle of the lamp, and the position lamps 10, the turn signal lamp 11 and the fog lamp 13 are symmetrically distributed on the upper side and the lower side of the reversing lamp 12 respectively. The turn signal lamps 11, 13 are lighted to have an elongated arc shape and extend from the vehicle outside to the vehicle inside, and the position lamp 10 is located outside the turn signal lamps 11, 13 and is semi-enclosed.

The full-LED combined tail lamp mainly comprises a transparent lens 1, an inner lens 2, a steering lamp thick wall 3, a fog lamp thick wall 4, a reversing lamp reflector 5, an LED module 6, an LED module support 7, a lamp shell 8 and a wire harness group 9. The LED modules 6 include six sets of sub-modules, namely two position light LED modules 6a and 6c, a turn light LED module 6b, a fog light LED module 6d, a reversing light LED module 6e and an LED module driving board 6f, and the five functional sub-modules are all connected with and controlled by the LED module driving board 6f, and are connected with and supply power to a vehicle power supply or a control system through the wire harness group 9. The position lamp LED module 6a is fixed on the LED module support 7 through hot riveting, the steering lamp LED module 6b is fixed on the LED module support 7 through hot riveting and is fixedly connected with the steering lamp thick wall 3 through a screw, and then the steering lamp LED module is integrally fixed on the lamp shell 8 through the screw. Similarly, the position lamp LED module 6c is fixed on the LED module support 7 through hot riveting, the fog lamp LED module 6d is fixed on the LED module support 7 through hot riveting, and then is fixedly connected with the fog lamp thick wall through a screw, and finally is integrally fixed on the lamp shell 8 through the screw. The backup lamp LED module 6e is fixedly connected with the backup lamp reflector by a screw, and then integrally fixed to the lamp housing 8.
