LiDAR integrated lamp device for vehicle

A Light Detection and Ranging (LiDAR)-integrated lamp device for a vehicle, the LiDAR-integrated lamp device including:

• a first light source of emitting light for beam patterns;
• a second light source spaced from the first light source and of emitting light for LiDAR sensing;
• a reflection unit of receiving the light for the beam patterns from the first light source and the light for the LiDAR sensing from the second light source, and configured of varying reflection angles for the light for the beam patterns and the light for the LiDAR sensing to change travel paths of the light for the beam patterns and the light for the LiDAR sensing;
• a first reflection mirror of receiving the light for the beam patterns reflected from the reflection unit, while reflecting the light for the beam patterns, and of emitting visible light for the beam patterns outwards of the vehicle;
• a second reflection mirror of receiving the light for the LiDAR sensing reflected from the reflection unit, of reflecting the light for the LiDAR sensing, and of emitting the reflected light for the LiDAR sensing outwards of the vehicle;
• a first optical system of projecting the light for the beam patterns reflected through the first reflection mirror outwards of the vehicle;
• and
• a second optical system for diffusing the light for the LiDAR sensing reflected through the second reflection mirror outwards of the vehicle,
• wherein the reflection unit has a central axis inclined at a first angle from a virtual vertical line,
• wherein the second light source is spaced from a connecting line connecting the first light source and the reflection unit by a second angle,
• wherein the second reflection mirror includes:
• a first reflector mounted to be downwardly spaced apart by the second angle from an optical axis of the light for the beam patterns traveling after being reflected by the reflection unit while being inclined at an angle equal to half of the second angle with respect to the light for the LiDAR sensing traveling after being reflected by the reflection unit;
• and
• a second reflector mounted to receive the light for the LiDAR sensing reflected by the first reflector while being inclined at an angle equal to half of the first angle with respect to a first disposition line of the second reflection mirror and the second optical system.
