Embodiment Construction

[0013] Refer figure 1 The reference numeral 1 represents the lighting device, in the illustrated non-limiting embodiment, the lighting device is a vehicle headlight. However, the described above can be applied to any vehicle lighting device equipped with a rotary lighting module. The lighting device 1 is constructed for in use along the optical axis O ( figure 1 ) Generate a designated light distribution, the optical axis O figure 1 The direction of the vehicle represented by the arrow is roughly flourishing.

[0014] The lighting device 1 includes a substantially cup-shaped housing 2, which is designed to be mounted on the vehicle, the vehicle is known and is not shown for the sake of simplicity. The housing 2 is formed by injection molding by the synthetic plastic material, and has a front inlet 3 in which the vehicle is used back to the vehicle and in the direction D (in the illustrated example, the forward travel direction D) of the vehicle; import 3 is typically closed by the...

Abstract

The invention relates to a lighting device (1) for a vehicle, which produces a prescribed light distribution along an optical axis and comprises a cup-shaped housing (2) and a plurality of rotating illuminators arranged in the cup-shaped housing (2) modules (5), each rotating lighting module (5) comprising an optical unit (9) and a printed circuit board (10), the optical unit (9) being carried by a support (8) and arranged about a pivot axis (A) Rotated, the printed circuit board (10) carries a plurality of LEDs (12, 13, 14) and has a rectangular shape; wherein the first LED (12) is arranged at the pivot axis (A) and at the longitudinal centerline of the printed circuit board , and a pair of second LEDs (13) are provided at a front corner (16) on the printed circuit board at positions tangent to a circle (C) centered on the pivot axis (A).

Description

[0001] Priority statement [0002] The present application claims priority to European Patent Application No. 17176962.3, filed on June 20, 2017, which is incorporated herein by reference. Technical field [0003] The present invention relates to a lighting device, which is equipped with a plurality of lighting modules using LED as a light source and has a rotational power to selectively provide more than one optical function, like a position light, directed light, welcome light, DRL (Japan Signal function and / or lighting function like a forward near-light (cross light) or fog, ultimately have advanced adaptive functions like AFS (adaptive functional systems) and DBL (dynamic corner lamp) . Background technique [0004] It is known in the art that a vehicle lighting device with a rotating LED lighting module is provided. [0005] For example, EP 2902701 discloses a device, wherein the illumination module includes a light source and at least one reflector, and wherein the reflect...
