Abstract

A LED vehicle lamp structure installed in a vehicle lamp assembly comprising a housing, a lens, and a reflector is disclosed to include standing boards each having a top edge, a bottom edge, a height defined between the top edge and the bottom edge, and LEDs. By means of the arrangement of the LEDs on the standing boards to match with the heights of the standing boards between the respective top edges and the respective bottom edges, the light-emitting heads of the LEDs constitute an array that fits the variation of the curvature of the reflector and lens of the vehicle lamp assembly, thereby greatly lowering the cost and the manufacturing difficulty of the vehicle lamp assembly.

Claims

1. A LED vehicle lamp structure installed in a vehicle lamp assembly comprising a housing, a lens and a reflector, said housing having a seat, said lens being covered on a front side of said housing, said reflector being mounted inside said housing between said seat and said lens, said reflector having a plurality of lamp holes, the LED vehicle lamp structure comprising:

a plurality of standing boards, said standing boards each having a bottom edge, a top edge disposed opposite to said bottom edge, a height defined between said bottom edge and said top edge, and a plurality of light emitting diodes respectively fixedly mounted on said standing boards adjacent to the top edges of said standing boards, said light emitting diodes each having a light-emitting head and a leg unit;

wherein said standing boards are respectively fastened to the seat of said housing to hold said light emitting diodes in such a manner that the light-emitting heads of said light emitting diodes are respectively inserted through the lamp holes of said reflector and suspending between said reflector and said lens.

2. The LED vehicle lamp structure as claimed in claim 1, wherein said standing boards include at least two standing boards that have different heights.

3. The LED vehicle lamp structure as claimed in claim 1, wherein said standing boards include at least one standing board that has at least two light emitting diodes disposed adjacent to the top edge of the associating standing board at different elevations.

4. The LED vehicle lamp structure as claimed in claim 1, wherein said standing boards include a plurality of circuit boards.

5. The LED vehicle lamp structure as claimed in claim 1, further comprising a plurality of lead wires that electrically connect the light emitting diodes of said standing boards together.

6. The LED vehicle lamp structure as claimed in claim 1, wherein said seat has a plurality of mounting holes respectively fastened to said housing with screws.

7. The LED vehicle lamp structure as claimed in claim 1, wherein said seat has a plurality of guide grooves symmetrically provided on two opposite inside walls thereof;

said standing boards are respectively inserted into the guide grooves of said seat.

8. The LED vehicle lamp structure as claimed in claim 7, wherein said guide grooves are respectively formed integral with the two opposite inside walls of said seat.

9. The LED vehicle lamp structure as claimed in claim 1, wherein said seat has fixedly mounted therein a circuit board, which has a plurality of insertion slots;

said standing boards each have at least one gold leg respectively inserted into said insertion slots to electrically connect the respective light emitting diodes to said circuit board.

10. The LED vehicle lamp structure as claimed in claim 1, wherein said light emitting diodes are selected from at least one of the groups of red light emitting diodes, green light emitting diodes, blue light emitting diodes, yellow light emitting diodes, and white light emitting diodes.
