Abstract
The optical device is intended to be placed in a housing to form a light signal lamp for a vehicle. The optical device includes, along the longitudinal direction: an input portion receiving rays emitted by a light source; a middle portion having two lateral faces spaced from each other along a transverse direction; an output portion including an output face through which the rays which have propagated in the optical device are emitted. The output portion comprises at least one module having lateral faces which, when viewed in the elevation direction, have an ogive shape and which define a front ridge extending substantially in a plane parallel to a plane.

An optical device intended to be placed in a housing to form a light signal lamp for a vehicle, the optical device being in the form of a block of transparent or translucent material having a longitudinal direction and comprising, along the longitudinal direction:
- an input portion configured to receive rays emitted by at least one light source;
- a middle portion having two lateral faces spaced from each other along a transverse direction orthogonal to the longitudinal direction;
- an output portion including an output face through which the rays which have propagated in the optical device are emitted;
- an elevation direction being defined as orthogonal to the longitudinal and transverse directions;
- wherein the output portion comprises at least one module having lateral faces which, when viewed in the elevation direction, have an ogive shape and which define a front ridge extending substantially in a plane parallel to the longitudinal and elevation directions.
A light signal lamp for a vehicle, comprising at least one optical device, the at least one optical device being in the form of a block of transparent or translucent material having a longitudinal direction and comprising, along the longitudinal direction:
- an input portion configured to receive rays emitted by at least one light source;
- a middle portion having two lateral faces spaced from each other along a transverse direction orthogonal to the longitudinal direction;
- an output portion including an output face through which the rays which have propagated in the optical device are emitted;
- an elevation direction being defined as orthogonal to the longitudinal and transverse directions;
- wherein the output portion comprises at least one module having lateral faces which, when viewed in the elevation direction, have an ogive shape and which define a front ridge extending substantially in a plane parallel to the longitudinal and elevation directions a housing receiving the at least one optical device, the housing including a base provided with a mounting for mechanical assembling to the vehicle and a transparent or translucent cover mounted on the base and disposed facing at least the output portion of the at least one optical device, the light signal lamp further comprising at least one light source placed facing the input portion of the at least one optical device.
