Abstract

An interior lamp for a vehicle may provide an interior lamp for a vehicle, including an air vent, the interior lamp including an air vent assembly disposed in a mounting aperture of a louver plate through screw-coupling and controlling the size of an air inflow aperture by a screw rotation operation to adjust an air volume flowing from an air duct to the air inflow aperture, and an interior lamp assembly disposed in a lower inner diameter portion of the air vent assembly through ball-joint coupling to be adjustable in irradiation direction of lamp light and including a discharge path that discharges the air volume passing through the air vent assembly into the interior.

First claim

What is claimed is:

1. An interior lamp for a vehicle, comprising an air vent, the interior lamp comprising:
an air vent assembly disposed in a mounting aperture of a louver plate through screw-coupling and controlling the size of an air inflow aperture by a screw rotation operation to adjust an air volume flowing from an air duct to the air inflow aperture,
wherein the air vent assembly comprises:
an air volume control fixing cylinder rotatably inserted into the mounting aperture of the louver plate and having a female screw on an inner diameter thereof; and
an air volume control actuating cylinder having a male screw formed on an outer diameter surface thereof to be coupled to the female screw and having a plurality of air inflow apertures penetratively formed therein and receiving an air volume from the air duct, wherein the air volume control actuating cylinder comprises a support plate integrally formed on a top surface thereof and having a size larger than the mounting aperture to be detachably supported by a top surface of the louver plate; and

an interior lamp assembly disposed in a lower inner diameter portion of the air vent assembly through ball-joint coupling to be adjustable in irradiation direction of lamp light and comprising a discharge path that discharges the air volume passing through the air vent assembly into the interior.

2. The interior lamp of claim 1 , further comprising an operation recognition ring press-fitted between an outer diameter surface of the air volume control fixing cylinder and an inner diameter surface of the mounting aperture of the louver plate to recognize a stage of the air volume when a user rotates the air volume control fixing cylinder.

3. The interior lamp of claim 2 , wherein the operation recognition ring comprises:
a circular ring body press-fitted into a press-fit groove formed in the outer diameter surface of the air volume control fixing cylinder; and
an elastic compression body integrally and protrusively formed on an outer diameter of the ring body and detachably inserted into the fixing groove formed along a circumferential direction of an inner diameter of the mounting aperture at a uniform interval.

4. The interior lamp of claim 1 , wherein the air volume control fixing cylinder comprises an air volume stage recognition mark formed at a predetermined location on the outer diameter surface thereof, and an undersurface of the louver plate comprises air volume control stage marks formed thereon around the mounting aperture.

5. The interior lamp of claim 1 , wherein the air volume control fixing cylinder comprises a stopper formed at an upper end of an inner diameter surface of the air volume control fixing cylinder, and the air volume control actuating cylinder comprises a flange integrally formed at a lower end of an outer diameter surface of the air volume control actuating cylinder to limit a maximum rise height of the air volume control actuating cylinder by being stopped by the stopper.

6. The interior lamp of claim 1 , wherein the interior lamp assembly comprises: an upper cover body having a plurality of air discharge ports penetratively formed therein and disposed in the inner diameter of the air volume control fixing cylinder of the air vent assembly through ball-joint coupling to be adjustable in angle; a lamp fixing socket having an air via port penetrating the outer circumference thereof and communicating with the air discharge port and integrally formed inside the upper cover body; and a lower cover body coupled to a lower end of the upper cover body to straightly guide light of the lamp in a downward direction.

7. The interior lamp of claim 6 , wherein the upper cover body comprises an auxiliary air discharge body integrally formed therein to penetrate an outer circumference of the lamp fixing socket and having a hollow straight tubular shape, and the auxiliary air discharge body comprises an auxiliary air discharge port formed therein to penetrate in a vertical direction.

8. The interior lamp of claim 6 , comprising a handler having a cylindrical shape and inserted into an inner diameter surface of a lower end portion of the lower cover body to handle the interior lamp assembly.
