Patent ID: 7534019

Claim:
An elliptical optical module, intended for a motor vehicle, comprising: a reflector intended to receive a light source, said reflector including a support piece, an intermediate piece attached to said support piece of said reflector, a shield comprising an optically active flap for obstructing at least part of the light rays when emitted by the light source and a support flap, said optically active flap including an active edge, said support flap comprising a top part and an opposing bottom part, said opposing bottom part of said support flap of said shield being rigidly fixed between said support piece of said reflector and said intermediate piece, a convex lens being disposed to receive at least a part of the light rays, said reflector includes at least one elastic fixing means for elastically holding or positioning said top part of said support flap of said shield against said support piece of said reflector, and a chromatics adjustment means for adjusting a position of said top part of said support flap of said shield relative to said reflector for correcting chromatic aberrations resulting from optical diffraction on said active edge of the shield, said at least one elastic fixing means cooperating with said chromatics adjustment means to elastically absorb position adjustments of said shield.
