Slim type lamp apparatus for vehicle

A lamp apparatus for a vehicle, the lamp apparatus comprising:

• a first light source for radiating light;
• and
• a first lens portion including:
• an incident portion through which the light radiated by the first light source is incident;
• a reflection portion extending from the incident portion to reflect and move the incident light;
• and
• an emission portion extending from the reflection portion and emitting the light reflected by the reflection portion,
• wherein the reflection portion diffuses a predetermined amount of light upon reflection of the light to form a diffusion beam pattern by the emission portion and condenses other light upon reflection to form a condensing beam pattern by the emission portion;
• wherein the reflection portion includes:
• a first reflection surface formed to reflect the light incident by the incident portion so that the light is moved toward a focus;
• a second reflection surface formed to reflect the light reflected by the first reflection surface so that the light is moved toward the emission portion;
• and
• a third reflection surface formed to reflect a predetermined amount of light reflected by the second reflection surface so that the corresponding light is moved toward the emission portion but moved in a direction different from a path of the light moved by the second reflection surface;
• and
• wherein the first reflection surface includes a diffusion reflection surface and a condensing reflection surface around an optical axis of the first light source so that the light reflected and moved by the diffusion reflection surface forms the diffusion beam pattern upon reflection by the second reflection surface, and
• the light reflected and moved by the condensing reflection surface is reflected by the second reflection surface and then reflected by the third reflection surface to form the condensing beam pattern.
