Lamp for vehicle

Abstract

The present invention relates to a lamp for a vehicle, wherein light is caused to be incident into a light guide panel from a side surface of the plate-shaped light guide panel, the light is propagated within the light guide panel by means of total reflection and scattered by a scattering pattern formed on a rear surface of the light guide panel so that the light can be radiated to a front surface of the light guide panel, and the light radiated to the front surface is then radiated forward with a predetermined pattern by means of a cover member provided with a lens pattern. A lamp for a vehicle according to the present invention comprises a housing having an opening through which light radiates; a light-transmitting cover member which has a light incidence plane and a light exit plane, and is fixedly installed on the housing to hermetically cover the opening of the housing and provided with a lens pattern formed on the light incidence plane and / or the light exit plane; a plate-shaped light guide panel which has a light incidence plane defined at a side surface thereof to receive light and a light exit plane defined at a front surface thereof to face the cover member and is provided with a scattering pattern for scattering light incident on the light incidence plane thereof toward the light exit plane thereof; a light source installed at a portion adjacent to the light incidence plane of the light guide panel to emit the light to the light incidence plane; and a reflection plate installed on a rear surface of the light guide panel to reflect the light toward a front surface of the light guide panel.

Description

technical field [0001] The present invention relates to lamps for vehicles, having a light guide panel, which can be used as headlights, fog lamps, backup lamps, headroom lamps, lamps for illuminating digital panels, tail lamps, brake lamps, turn signals and lamps mounted to the exterior of the vehicle Emergency strobe lights or interior lights mounted to the interior of the vehicle. More specifically, the present invention relates to a lamp for a vehicle in which light is caused to be incident into a light guide panel from a side surface of a plate-shaped light guide panel, the light propagates inside the light guide panel by total reflection and passes through a hole formed in the light guide panel. The scattering pattern formed on the rear surface is scattered so that light can be emitted onto the front surface of the light guide panel, and the light irradiated to the front surface is then emitted forward in a predetermined pattern through the cover member provided with the...
