Abstract
A vehicle lamp, which reflects light of a predetermined color using ambient light and emits light of a predetermined pattern using internal light, includes: a light source that emits light; a lens disposed in a light emission path of the light source; and a main film attached to the lens. The main film includes: a color layer that reflects ambient light in a predetermined color; and a functional layer that selectively transmits the light emitted from the light source.
Claims20
A vehicle lamp comprising:
- a light source that emits light;
- a lens disposed in a light emission path of the light source;
- and
- a main film attached to the lens,
- wherein the main film includes:
- a color layer that reflects ambient light in a predetermined color;
- and
- a functional layer that selectively transmits the light emitted from the light source, and
- wherein the functional layer selectively transmits the light from the light source therethrough using a piezoelectric method.
