Abstract

A vehicle lamp device is provided and includes a housing having an accommodating portion with an open side and a connector pin disposed in the accommodating portion. A light source unit is disposed in the accommodating portion and includes one or more light sources configured to irradiate light toward the open side of the accommodating portion. Additionally, a lens is coupled to the open side of the accommodating portion and is configured to transmit light irradiated from the light sources. The connector pin is integrally formed with the housing by insert injection, and the light source unit includes a printed circuit board (PCB) having an aperture through which an end of the connector pin passes and the light sources which are installed on the PCB and irradiate light.

Claims

1. A vehicle lamp device, comprising:

a housing having an accommodating portion with an open side and a connector pin disposed within the accommodating portion;

a light source unit disposed within the accommodating portion and including one or more light sources configured to irradiate light toward the open side of the accommodating portion; and

a lens coupled to the open side of the accommodating portion and configured to transmit light irradiated from the light sources,

wherein the connector pin is integrally formed with the housing by insert injection, and the light source unit includes a printed circuit board (PCB) having an aperture through which an end of the connector pin passes and the light sources which are installed on the PCB and irradiate light.

2. The vehicle lamp device of claim 1, wherein the accommodating portion includes one or more guide protrusions which protrude inward, and the PCB includes one or more guide grooves inserted into the guide protrusions and moved along the guide protrusions.

3. The vehicle lamp device of claim 1, wherein the accommodating portion includes one or more guide grooves and the PCB includes one or more guide protrusions inserted into the guide grooves and moved along the guide grooves.

4. The vehicle lamp device of claim 1, wherein the end of the connector pin which passes through the aperture is soldered to the PCB.

5. The vehicle lamp device of claim 1, wherein the lens includes:

a first lens configured to diffuse light irradiated from the light sources; and

a second lens configured to refract light diffused by the first lens in a predetermined pattern.

6. The vehicle lamp device of claim 1, wherein the lens is coupled to the open side of the accommodating portion by ultrasonic welding.

7. The vehicle lamp device of claim 1, further comprising:

a pad coupled to the housing to prevent the introduction of foreign matter into the housing.

8. The vehicle lamp device of claim 7, wherein the housing further includes:

an extending portion which extends outward from the open side of the accommodating portion,

wherein the extending portion includes one or more coupling hooks which protrude toward the pad, and

wherein the pad includes one or more coupling grooves into which the coupling hooks are inserted and hooked.

9. A method of manufacturing a vehicle lamp device, the method comprising:

disposing a light source unit having a PCB and a light source, within a housing through an open side of the housing;

passing an end of a connector pin integrally insert-injected into the housing, through an aperture formed in the PCB of the light source unit and soldering the end to the PCB; and

coupling a lens to the open side of the housing.

10. The method of claim 9, wherein in the disposing of the light source unit within the housing, guide grooves respectively formed at both ends of the PCB are inserted into guide protrusions formed inside the housing and moved along the guide protrusions.

11. The method of claim 9, wherein in the disposing of the light source unit in the housing, guide protrusions respectively protruding from both sides of the PCB are inserted into guide grooves formed inside the housing and moved along the guide grooves.

12. The method of claim 9, wherein in the coupling of the lens to the open side of the housing, the lens is coupled to the open side of the housing by ultrasonic welding.

13. The method of claim 9, further comprising:

coupling a pad to the housing to prevent the introduction of foreign matter into the housing.
