Embodiment Construction

[0028] In particular, the object of the invention is to provide a lighting device DE with a light source SL and a shade M, which ensures at least one lighting function.

[0029] In what follows, as a non-limiting example, it is considered that the lighting device DE is intended to be fitted on an optical unit BO of a vehicle of motor type, such as a car. But the invention is not limited to this application. In fact, the lighting device DE can be a piece of equipment itself (optionally including its own housing), or else be part of another piece of equipment than the vehicle optical unit. Furthermore, the lighting device DE may be part of any (land, sea (or river), or air) vehicle, any installation (including industrial type installations), any instrument or (system), and any building.

[0030] Furthermore, in the following, as a non-limiting example, it is considered that the optical unit BO (comprising at least one lighting device DE) is the rear end that ensures at least on...

Abstract

A lighting device (DE) comprising at least one light source (SL) capable of generating photons and a shield (M) capable of passing said generated photons at predetermined locations. The shutter (M) comprises a front surface (FV) oriented towards the outside and provided with three-dimensional elements (ET), each of which comprises: an opaque main surface (FP); and at least one side surfaces (FL), said at least one side surface is inclined with respect to said main surface (FP) and ensures that said main surface (FP) is separated from the main surface (FP) of at least one adjacent other three-dimensional element (ET). and at least one side surface is transparent to constitute one of the predetermined locations through which the generated photons pass.

Description

technical field [0001] The invention relates to a lighting device, more precisely to a lighting device comprising at least one light source associated with a mask to ensure at least one lighting function. Background technique [0002] In the following, "illumination device" is understood as meaning a lighting device which can ensure at least one lighting function for lighting or signaling or optionally a decorative lighting effect. [0003] In some fields, for example in the field of vehicles of optionally motorized type, lighting devices such as those defined above are used to ensure at least one lighting function, such as a position light (or small light or signal light) function or a daytime running light (DRL (Daytime running Light (Lamp)) - a luminous signal that automatically lights up when the vehicle is running during the day) function. [0004] The shutter of this type of lighting device is usually a part of plastic material responsible for blocking the passage of ...
