Abstract
A vehicle lamp that reflects or obstructs light using a film filled with metal flakes, thereby emitting light in a preset pattern includes a light source that emits light, a main film disposed in a light emission path of the light source, and a magnetic field generating unit that generates a magnetic field that influences the main film. The main film includes a functional layer that selectively transmits the light depending on the magnetic field.

A vehicle lamp comprising:
- a light source that emits light;
- a main film disposed in a light emission path of the light source;
- and
- a magnetic field generating unit that generates a magnetic field that influences the main film,
- wherein the main film includes a functional layer that selectively transmits the light based on the magnetic field,
- wherein the functional layer includes a functional cover, a filler provided inside the functional cover, and metal flakes provided inside the functional cover and configured to move within the filler under the influence of the magnetic field,
- wherein the main film further includes a color layer that converts the light emitted by the light source into a preset color, and
- wherein the color layer is configured to reflect ambient light in the preset color to allow the ambient light to be reflected by the color layer and to be observed in the preset color from exterior of the vehicle lamp.
