Abstract
An optical module for a motor vehicle headlight comprising a reflector having an optical axis and at least one focus, a light source placed in the vicinity of the focus to be reflected, and a transparent optical deviation element placed in front of part of the reflector and comprising a lens referred to as a “square lens”, the reflector being placed at the rear of the lens, the optical deviation element being able to provide an essentially horizontal spread of the light. The exit face of the “square lens” is tangent to a plane disposed obliquely with respect to the optical axis.

15. An optical module for a motor vehicle headlight, said optical module comprising:
-
a reflector having an optical axis and at least one focus, a light source placed in the vicinity of said at least one focus of the reflector, and a lens in front of said reflector for providing a substantially horizontal spread of the light, wherein, at least one of an exit face or an entry face of said lens is generally tangent to a plane disposed obliquely with respect to said optical axis and an entry face that forms an angle with respect to a plane that is normal to said optical axis wherein said lens comprises at least one cylindrical face with vertical generatrices. - View Dependent Claims (16, 17, 18, 19)
