Abstract
Described is an optical device including: a printed circuit board; an LED mounted on the printed circuit board; a light guide layer that embeds the LED therein and includes a reflective surface and an exit surface; and a reflective pattern layer formed on the reflective surface of the light guide layer, wherein the reflective surface of the light guide layer includes a curved shape such that light of the LED is entirely internally reflected using the reflective pattern layer and emitted from the exit surface. The optical device implements a stereoscopic light emitting image using the light guide layer including the curved reflective surface that entirely internally reflects LED light in a lamp structure of a vehicle.

An optical device comprising:
- a printed circuit board (PCB);
- a light-emitting diode (LED) mounted on the PCB;
- a light guide layer embedding the LED therein and including a reflective surface and an exit surface;
- and
- a reflective pattern layer disposed on the reflective surface of the light guide layer,
- wherein the reflective surface of the light guide layer has a curved shape such that light of the LED is entirely internally reflected using the reflective pattern layer and emitted from the exit surface.
A vehicle comprising:
- a vehicle body;
- a lamp structure disposed in at least one of a front surface and a rear surface of the vehicle body;
- and
- an optical device embedded in the lamp structure,
- wherein the optical device includes:
- a printed circuit board (PCB);
- a light-emitting diode (LED) mounted on the PCB;
- a light guide layer configured to embed the LED therein and including a reflective surface and an exit surface;
- and
- a reflective pattern layer disposed on the reflective surface of the light guide layer, and
- wherein the reflective surface of the light guide layer has a curved shape such that light of the LED is entirely reflected internally using the reflective pattern layer and emitted from the exit surface.
