Rotating lighting module for vehicles and associated lighting device for vehicles

Abstract

A lighting module (5) for vehicles includes a light source (6), a reflector (7) and an actuator (8) to rotate the reflector relative to the light source around a first axis (A); wherein the reflectorforms, together with a lens (9) assembled angularly rigid therewith, a rotating unit (10) powered by the actuator and the light source, the actuator and the rotating optical unit are operatively associated with a framed support (11) formed by a rigid metallic structure; the rotating optical unit (10) is supported in idly manner solely by a bottom portion (14) of the framed support (11) as a firstsub-assembly (15) completely independent of an upper portion (16) of the framed support (11) bearing the light source (6), which forms, with a printed circuit board (12) and electronic components (13), a second sub-assembly (18) supported solely by the upper portion (16) of the framed support (11), the first sub-assembly (15) being mechanically disconnected in rotation from the second sub-assembly(18).

Description

[0001] priority statement [0002] This application claims priority from European Patent Application No. 17185381.5 filed on 08.08.2017, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to a rotating lighting module for a vehicle and a lighting device equipped with a plurality (ie at least two) of such lighting modules with rotation capability, preferably in conjunction with a non-rotating main lighting module Associated to selectively provide multiple lighting distributions through the same lighting fixture. Background technique [0004] Lighting arrangements for vehicles comprising a plurality of individual lighting modules, some of which are provided with rotating elements, such as rotating reflectors, are known in the art. [0005] EP2902701 and FR3022322A1 disclose a lighting module comprising a fixed light source consisting of LEDs and a rotating support with two opposing surfaces, one surface constitu...

Problems solved by technology

[0007] This solution on the one hand ensures a reliable pivoting of the rotating part of the lighting module, but on the other hand is difficult to implement, is bulky, complicates, slows and expensive the assembly operation of the lighting module and above all does not allow standardization of the lighting modules components, so that the lighting modules that are apparently the same in the whole lighting device but are designed to be arranged in different positions actually have different (even slightly different) parts from each other, thus increasing the production cost

[0008] Finally, in particular the rotation of the upper pin in its seat set through the printed circuit board may wear the swivel seat causing noise and in some cases the generation of dust which can deposit on the optics of the module , thereby compromising its lighting performance
