Embodiment Construction

[0019] figure 1 A vehicle headlamp 1 according to an embodiment of the invention is shown.

[0020] As shown, the headlamp comprises a main module 2 configured to emit a main beam 31, 41, 51, 61, preferably a high beam / low beam, ie capable of emitting a low beam or a high beam. dual function module, the main module includes one or more motors (not visible), the one or more motors configured to follow the figure 1 The vertical and horizontal arrows shown adjust the position and azimuth of the main module. Although this is figure 1 Not visible above, said main beam of the dipped beam may have a flat cross-section, i.e. the photometry (illuminated area) of said main beam is substantially rectangular without an enlarged illuminated area for the roadside, Or it may have an enlarged cross-section of X° (for example 15°) so that the main beam also illuminates the illuminated area of ​​the roadside.

[0021] Likewise, the headlamp comprises a plurality of supplementary modules 3, ...

Abstract

The invention relates to a vehicle headlight (1) including: a main lighting module (2) arranged to emit a main light beam (31, 41, 51, 61) corresponding to a low-beam/high-beam headlight ; a plurality of complementary lighting modules (3, 3', 3") arranged such as to each emit a complementary light beam (32, 33, 34, 42, 43, 44, 52, 53, 54, 62, 63, 64) separate from said main light beam; an adjustment means (4) for adjusting the elevation and azimuth of each of said lighting modules (2, 3, 3', 3"); and a control unit, characterised in that said means for adjusting the elevation and azimuth is arranged such as to adjust the elevation and the azimuth of each of said lighting modules independently of one another in response to an order from said control unit.

Description

technical field [0001] The present invention generally relates to a headlamp for fitting on a motor vehicle. Background technique [0002] High beam lighting devices fitted to motor vehicles are known from the prior art. These devices are typically part of headlamps or headlights that are located at the front of the vehicle and project a beam of light toward the front of the vehicle to illuminate the road. These devices usually comprise a lighting module comprising a light source, a reflector, a printed circuit board (in the case of electroluminescent diodes as light source), a lens for projecting the emitted light forward, and a to the glass used to protect the device. The problem with these devices is that they are too rigid in terms of modularity. In fact, the lighting module emits a single type of beam so that the photometry of the headlights (i.e. the illuminated area in front of the vehicle) is static regardless of the driving conditions, unless elements such as cov...
