Abstract
(EN)
A condenser structure for a vehicle, belonging to the technical field of automobile lighting, and comprising a condensing body; the front end of the condensing body is a light emitting surface (1), the rear end of the condensing body is a light condensing end (2), the light condensing end (2) is a structure which protrudes toward the rear as a whole, is recessed at the center, and has a recessed bottom surface (21) protruding backwardly, recessed inner side surfaces (22) are curved surfaces having a collimating effect on the light emitted from the light source, the bottom surface (21) is a surface of revolution, and the rotation center line thereof passes through the light emitting surface (1) forwardly; and the radially outer surface of the condensing end (2) comprises several cylindrical surfaces (23) and several cutting flat surfaces (24), the cylindrical surfaces (23) and the cutting flat surfaces (24) being connected in sequence, the cylindrical surfaces (23) being totally reflective surfaces, the generatrix of the cylindrical surfaces (23) being perpendicular to the rotation center line of the bottom surface (21), and the cylindrical surfaces (23) being arranged corresponding to the inner side surfaces (22). Such a condenser structure for a vehicle ensures that no light reaches the cutting flat surfaces, and there is no stray light at the cutting flat surfaces, so that this structure is suitable for various thick wall member structures in which a condenser needs to be cut.

La présente invention concerne une structure de condenseur pour un véhicule, appartenant au domaine technique de l'éclairage d'automobile, et comprenant un corps de condensation ; l'extrémité avant du corps de condensation est une surface électroluminescente (1), l'extrémité arrière du corps de condensation est une extrémité de condensation de lumière (2), l'extrémité de condensation de lumière (2) est une structure qui fait saillie vers l'arrière dans son ensemble, est évidée au centre, et présente une surface inférieure évidée (21) faisant saillie vers l'arrière, des surfaces latérales internes évidées (22) sont des surfaces incurvées ayant un effet de collimation sur la lumière émise par la source de lumière, la surface inférieure (21) est une surface de révolution, et sa ligne centrale de rotation passe à travers la surface électroluminescente (1) vers l'avant ; et la surface radialement externe de l'extrémité de condensation (2) comprend plusieurs surfaces cylindriques (23) et plusieurs surfaces planes de coupe (24), les surfaces cylindriques (23) et les surfaces planes de coupe (24) étant raccordées en séquence, les surfaces cylindriques (23) étant des surfaces totalement réfléchissantes, la génératrice des surfaces cylindriques (23) étant perpendiculaire à la ligne centrale de rotation de la surface inférieure (21), et les surfaces cylindriques (23) étant agencées en correspondant aux surfaces latérales internes (22). Ladite structure de condenseur pour un véhicule garantit qu'aucune lumière n'atteint les surfaces planes de coupe, et il n'y a pas de lumière parasite au niveau des surfaces planes de coupe, de telle sorte que cette structure est appropriée pour diverses structures d'élément de paroi épaisse dans lesquelles un condenseur doit être coupé.
