CONDENSER STRUCTURE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/063150
Kind Code:
A1
Abstract:
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.
