Abstract

A vehicle lamp includes a light emitting diode (LED) drive module (LDM) including a printed circuit board (PCB) on which an electronic element for driving a light source is mounted, and an electromagnetic interference (EMI) cover coupled to the PCB to surround the electronic element, and a lamp housing including a guide portion formed in a first direction such that the LDM is coupled thereto in a sliding manner and a seating portion in surface contact with a tip portion of the LDM in a coupled state, wherein a cover pressing portion that protrudes in a coupling direction of the LDM and presses the EMI cover in a second direction may be formed in the seating portion.

First claim

What is claimed is:

1. A vehicle lamp comprising:
a light emitting diode (LED) drive module (LDM) comprising a printed circuit board (PCB) on which an electronic element for driving a light source is mounted, and an electromagnetic interference (EMI) cover coupled to the PCB and surrounding the electronic element; and
a lamp housing comprising a guide portion formed in a first direction such that the LDM is coupled thereto in a sliding manner and a seating portion is in contact with a tip portion of the LDM in a coupled state,
wherein a cover pressing portion that protrudes in a coupling direction of the LDM and presses the EMI cover in a second direction different from the first direction is formed in the seating portion,
the lamp housing being provided with a fixing rib protruding from an upper portion and a lower portion of the PCB, and
the fixing rib comprising an upper fixing rib and a lower fixing rib that support the upper portion and the lower portion of the PCB, respectively.

2. The vehicle lamp of claim 1 , wherein the cover pressing portion presses an upper portion of the EMI cover towards the PCB.

3. The vehicle lamp of claim 1 , wherein the second direction is a direction perpendicular to the first direction on a vertical cross section.

4. The vehicle lamp of claim 3 , wherein the first direction is a direction in which the LDM is inserted, and the second direction is a direction perpendicular to a direction in which the LDM slides.

5. The vehicle lamp of claim 1 , wherein the upper fixing rib and the lower fixing rib are inclined downward in a longitudinal direction of the PCB.

6. The vehicle lamp of claim 1 , wherein the cover pressing portion has an inclined structure in which a thickness thereof increases toward the seating portion.

7. The vehicle lamp of claim 6 , wherein a pressure applied to the EMI cover increases toward the seating portion via the inclined structure.

8. The vehicle lamp of claim 1 , wherein the EMI cover comprises a cover portion that covers a top of the PCB, and an extension portion extending in a direction from the cover portion toward the PCB.

9. The vehicle lamp of claim 8 , further comprising:
a plurality of grounding portions formed in the extension portion of the EMI cover; and
at least a fixing portion fixed to the PCB between the plurality of grounding portions.

10. The vehicle lamp of claim 8 , further comprising:
a wing-shaped coupling portion extending outward from the extension portion and screw-coupled to the lamp housing.
