Patent ID: 8602618

Claim:
An intelligent head lamp assembly for a vehicle, comprising: a light source to irradiate light; a reflector reflecting the light irradiated from the light source; a beam pattern variable unit having at least a digital micro-mirror device (DMD) that selectively change direction of the light reflected by the reflector to a predetermined angle; a projection lens optical system irradiating the light selectively reflected by the beam pattern variable unit onto a road surface; and a prism installed between the reflector and the beam pattern variable unit to reflect the light reflected by the reflector to the at least a digital micro-mirror device; wherein the prism includes: a first prism surface that reflects the light reflected by the reflector to at least digital micro-mirror device; a second prism surface that reflects again the light which is reflected by the first prism surface; and a third prism surface that reflects again the light reflected by the second prism surface in a front direction of the vehicle such that the light is not incident to the projection lens optical system.
