- each elementary optical module is shaped to capture the light beam emitted by the associated diode and straighten it in a direction substantially parallel to the illumination direction.
- These elementary optical modules are in particular distinct from each other, without contact with each other in a direction transverse to the direction of illumination.
- Each light beam consisting of all the light rays from a light emitting diode, is thus propagated and guided in the desired direction.
- a light-emitting diode generally emits a plurality of light rays in several directions: the light beam consisting of these rays thus generally has a conical shape.
- the direction of a light beam is considered as the direction of the axis of symmetry of the cone delimiting the light beam.
- a light beam is parallel (or substantially parallel) to a lighting direction, when the axis of symmetry of the cone delimiting it is parallel (or substantially parallel) to the illumination direction.
