Abstract
A lamp apparatus for a vehicle which radiates only a p-polarized beam without radiating an s-polarized beam which is reflected by water collecting on a road surface by filtering light which is radiated to a road surface which is wet by rain, preventing reflection of light by water, whereby it is possible to prevent light from blinding the people in oncoming vehicles, so safety from oncoming vehicles is secured and since light having a uniform waveform is radiated, lighting feeling is improved.
Claims15
A lamp apparatus for a vehicle, the lamp apparatus comprising:
- a light source that radiates light;
- a polarizing filter that receives the light radiated from the light source and reflects forward a first incident light of a first-directional polarized beam and transmits a second-directional polarized beam, depending on polarizing directions of the polarizing filter;
- a reflecting mirror that receives the second-directional polarized beam that has passed through the polarizing filter, and reflects a second incident light of the second-directional polarized beam forward thereof;
- a wavelength plate which is mounted ahead of the reflecting mirror, receives the second incident light of the second-directional polarized beam reflected by the reflecting mirror, and converts the second incident light of the wavelength plate into a third-directional polarized beam which is a same as the first-directional polarized beam reflected by the polarizing filter;
- and
- a reflector which is mounted ahead of the polarizing filter and the reflecting mirror, receives the first-directional polarized beam reflected by the polarizing filter and the third-directional polarized beam converted by the wavelength plate, and changes a course of the first-directional polarized beam and the third-directional polarized beam so that the first-directional polarized beam and the third-directional polarized beam are sent out to a road surface.
