The lens 4 is relatively thick, in appearance, the lens 4 will be perceived as bright rather than the parabola of the reflector 5.
La figure 3 présente une vue de profil en coupe d'un module optique 1 compact et standardisé suivant un second mode de réalisation de l'invention. Le module optique 1 comprend le support 3 commun pour tous les types de modules, constituant l'ossature du module optique 1 sur lequel vient se clipper, la lentille 4 suivant l'axe longitudinal à l'avant du support 3 et le réflecteur 5 suivant l'axe longitudinal à l'arrière du support 3. Le porte 6 source lumineuse 7 étant lui-même clippé sur le réflecteur 5.

Ce module optique 1 comporte un réflecteur 5 ayant un foyer « classique » dans lequel la LED émet un rayonnement 11 suivant un cône, ce rayonnement 11 est redirigé dans l'axe par le biais de la parabole du réflecteur 5, ce rayonnement 11 traverse ensuite la lentille 4 qui ne modifie pas le trajet des rayons lumineux. Dans cette configuration, la lentille est plus mince, la parabole doit être suffisamment grande (grande focale) afin qu'à une certaine distance, le module optique en fonctionnement soit perçu comme possédant une dimension lumineuse relativement importante.

The lens 4 has its face curved front and its concave rear face and the parabolic focal point 5e of the reflector 5 covers the entire height of the lens 4. This optical module 1 comprises a reflector 5 having a "conventional" focus in which the LED emits radiation 11 in a cone, this radiation 11 is redirected in the axis through the parabola of the reflector 5, this radiation 11 then passes through the lens 4 which does not change the path of the light rays. In this configuration, the lens is thinner, the parabola must be sufficiently large (large focal length) so that at a certain distance, the optical module in operation is perceived as having a relatively large light dimension. The parabola of the reflector 5 will be perceived as luminous with respect to the lens 4.
Ainsi, le module optique 1 peut avantageusement être décliné en plusieurs type de feux, tout en possédant des pièces communes telles que le support 3 et éventuellement le porte 6 source lumineuse, tout en offrant une gamme d'assemblage des différentes pièces entre elles simple et facile . Thus, the optical module 1 can advantageously be declined in several types of lights, while having common parts such as the support 3 and possibly the light source door 6, while offering a range of assembly different parts between them simple and easy.
