The early car lamp modeling is blunt, and it is point light, which lacks modernity and individuality. Nowadays, with the progress of LED technology, the car lamp design gradually evolves into a modeling with stronger line feeling, uniform light and three-dimensional feeling. However, although the application of multi-LED light source brings many advantages, it also brings new challenges.

The light guide plate is provided with a light transmitting surface and a light emitting surface. The light transmitting surface includes at least one beam control area. The first light source component is arranged facing the first light incident surface so that the position light emitted by the first light source component enters the light guide rod through the first light incident surface, is reflected by the reflective surface to the beam control area, and exits through the beam control area to the light emitting surface. The second optical element is connected to the bracket and has a second light-incident surface. The second light source component is positioned facing the second light-incident surface so that the brake light emitted by the second light source component passes through the second light-incident surface, enters the second optical element, and exits through the beam control area to the light-emitting surface.

2. The taillight light-emitting structure as described in claim 1, characterized in that, The beam control area is provided with a plurality of grooves, which are arranged at intervals. Each groove extends away from the second optical element, so that the position light emitted by the first light source component enters the light guide rod through the first light incident surface, is reflected by the reflective surface to the groove wall, and exits through the groove wall to the light emitting surface.

3. The taillight light-emitting structure as described in claim 1, characterized in that, The light-transmitting surface also includes a light-transmitting area, and the number of the beam control areas is two, with the two beam control areas respectively disposed on both sides of the light-transmitting area along the first direction.

4. The taillight light-emitting structure as described in claim 1, characterized in that, The reflective surface is provided with reflective optical teeth.

5. The taillight light-emitting structure as described in claim 1, characterized in that, The second optical element includes a transparent inner lens and a condenser connected to each other. The transparent inner lens is connected to the bracket. A second light-incident surface is provided on one side of the condenser so that the brake light emitted by the second light source component passes through the second light-incident surface and enters the condenser and the transparent inner lens in sequence, and then exits through the light-transmitting surface to the light-emitting surface.

6. The taillight light-emitting structure as described in claim 5, characterized in that, The transparent inner lens is detachably connected to the bracket.

7. The taillight light-emitting structure as described in any one of claims 1 to 6, characterized in that, The taillight light-emitting structure also includes a decorative frame, which is connected to the bracket and is positioned toward the light guide bar so that the decorative frame can block the light guide bar.

8. The taillight light-emitting structure as described in claim 7, characterized in that, The decorative frame is detachably connected to the bracket.

9. The taillight light-emitting structure as described in any one of claims 1 to 6, characterized in that, The first light source component includes a first circuit board and a first light-emitting element connected to each other. The first circuit board is connected to the bracket. The first light-emitting element is disposed facing the first light-incident surface. The first light-emitting element is used to emit the light rays of the position light. And / or, The second light source component includes a second circuit board and a second light-emitting element that are interconnected. The second circuit board is connected to the bracket, and the second light-emitting element is disposed facing the second light-incident surface.
