Definitions
- the invention relates to a vehicle lighting device, in particular daylighting diodes, and to a vehicle equipped with such a system.
- the invention belongs to the field of lighting and signaling structures of vehicles, and more particularly - but not exclusively - to daytime running lights (abbreviated “DRL” initials "Day time Running Lamp” in terminology English).
- DRL daytime running lights
- lighting is provided by a light source - an incandescent lamp, an induction lamp or a light emitting diode - in connection with a concave reflector which concentrates the light on a collimator, surrounded by a black mask, to emit a beam of light parallel to the outside of the vehicle.
- ice is integrated in a housing front or rear of the vehicle, and an ice comes to close the housing to protect the lighting elements of aggression from outside the vehicle.
- the ice is convex and smooth to comply with the standards, in particular Regulation R26 of the United Nations Economic Commission for Europe (UNECE).
- UNECE United Nations Economic Commission for Europe
- this ice remains advantageously in the extension of the curvature of the surrounding bodywork.
- Patent document FR 2 708 334 discloses a lighting or signaling device comprising an ice cream having a lateral peripheral part made of plastic material loaded with reflective particles. This realization aims to hide the areas of dark appearance, the appearance of seeing inhomogeneous lighting between the lighting ranges, as well as allowing front and side visibility in the event of a traffic light.
- this solution does not improve the directivity of the lighting and the many areas of darkness or inhomogeneity remain difficult to eliminate.
- US Patent 1,888,995 discloses an automobile headlight equipped with an ice associated with a concave reflector.
- the ice In order to obtain a beam of parallel light output over the entire headlight, the ice has a planar main portion forming a ring and a central portion forming a concave portion mounted on a convex central lens.
- the profile of the ice then has a complex structure: a circular projection in the flat part, a reflective bottom wall in the concave portion and a particular cut of this concave portion.
- the main purpose of the invention is to provide such lighting in a simple and efficient manner, without resorting to complex shape reflection portions, in particular masks or specific collimators.
- the invention provides for the use of a single lens for peripheral masking and central convex collimation.
- the present invention more specifically relates to a vehicle lighting device comprising a housing housing a concave reflector and a source of light radiation arranged so as to come through, after reflection on the concave reflector, a outlet ice mounted on said housing.
- said mirror has a peripheral portion having an area at least partially concave, able to mask the light radiation, and coupled to a transparent central portion generally convex, able to collimate said light radiation when it passes through.
- the peripheral portion of the ice forms at the end an annular return adapted to fit the vehicle body, the annular return extending between a front edge and at least one inner end adapted to be inserted into a housing of said housing;
- the at least partially concave zone of the peripheral part of the ice generally has a mean curvature in longitudinal section such that the convex central portion of the ice remains non-contact, both in static conditions and in motion, with a sphere of 100 mm in diameter resting on the front edge of ice;
- the at least partially concave zone of the peripheral portion of the ice generally has a curvature of mean value which can vary between a maximum value, compatible with the dimensions of the case, and a value tending towards zero, corresponding to a conical shape, this average curvature value respecting the non-contact condition defined above;
- the at least partially concave zone of the peripheral portion of the ice is of material chosen between opaque black crystal glass, a black plastic material and a composite material loaded with carbon black;
- the ice is formed of a single piece of crystal glass, the central collimation portion being transparent crystal glass;
- the at least partially concave zone constitutes a main portion of the frontal projection ice
- the light source is at least one light emitting diode attached to a support, made of plastic material, in particular PCB, composite material or any material of strength and equivalent weight.
- the invention also relates to a set of DRL daytime running lamps comprising several lighting devices described above, mounted adjacent and integrated in a protective housing, and to a motor vehicle comprising at least two lighting devices or two sets of daytime running lamps as defined above, arranged at the front and / or at the rear.
- the qualifier "front” refers to the vehicle lighting device position in the extension of the bodywork surrounding the lighting device.
- the qualifier “internal” refers to the space defined in a housing of the lighting device, beyond the frontal position and the term “annular” means cylindrical revolution without being necessarily circular.
- the terms “upper”, “lower” and “horizontal” refer to the position of vehicle elements when the vehicle is in standard operation.
- the term “longitudinal” refers to a plane substantially parallel to the overall plane of symmetry passing through the vehicle from front to back.
- FIG. 1 a schematic longitudinal sectional view of a first embodiment of a lighting device according to the invention
- FIG. 2 is a view in longitudinal section of another exemplary embodiment of a lighting device according to the invention with a light-emitting diode, and
- FIG. 3 a perspective view of a set of DRL daytime running lights, seen in longitudinal section according to Figure 2.
- a lighting device 1 is arranged between the upper part 2s and the lower front part 2i of the body of a vehicle.
- the lighting device 1 is here at the front of the vehicle, but it could just as well be located at the rear.
- This lighting device 1 comprises a housing 10 open towards the front position FR in dashed lines (in extension of the bodywork) and forming at the end a housing 1 1.
- the housing 10 houses a concave reflector 12 and a light source 13.
- the light source 13 is arranged and oriented on a support 14.
- the lighting device 1 is equipped with a window 20 which forms, at its upper and lower ends, a tip 21 which is fixed in the housing 1 1 of the housing 10.
- the window 20 has a peripheral portion 22 having a concave zone 22C and coupled to a convex central portion 23.
- the mirror 20 has a symmetry with respect to a substantially horizontal median plane P.
- the ice 20 is formed of a single piece of crystal glass.
- the peripheral portion 22 is made of carbon black filled crystal glass material to mask the light radiation, and the convex central portion 23 is made of transparent, uncharged crystal glass material to collimate the unmasked light beam F1.
- the assembly consisting of the support 14, the light source 13 and the concave reflector 12 is configured, sized and arranged so that the light beam F1 passes through the convex central portion 23 of the window 20.
- the light radiation limited in FIG. 1 by the radii R1 and R2, collimated fate of the convex central portion 23 along the parallel beam F2.
- the concave zone 22C is dimensioned so that the convex central portion 23 is at a sufficient distance D from the FR front position for the 26 Regulation of the Economic Commission is respected: this regulation states, in particular, that the parts of the outer surface of a vehicle 'can not be touched, both in static conditions and in motion, by a sphere 100 mm in diameter for the United Nations (UN / ECE) Europe'.
- the concave zone 22C constitutes a main portion of the ice 20 projected onto the front position FR.
- annular return 24 to fit the upper and lower parts, 2s and 2i, of the vehicle body.
- This annular return 24 is continuous, which appears with reference to FIG.
- the annular return 24 extends longitudinally between a front flange 25 - aligned on the front position FR in continuity of the upper part of body 2s - and the inner end 21 being inserted into the housing 1 1 of the housing 10.
- FIG. 2 Another example of a light-emitting diode lighting device 1 'is illustrated by the longitudinal sectional view of FIG. 2.
- the housing 30 - provided with its end housing 31 -, and the ice 40 - with its masking peripheral portion 42 extended by its central part forming a convex crystal zone 43 - generally take up the configuration and functions of the housing 10 and the ice 20.
- the peripheral portion 42 of the ice 40 is composed of a front flange 45 extends the annular end return 44 which is fixed in the housing 41 formed by the end 31 of the housing 30.
- the convex crystal zone 43 is an optical zone which makes it possible to obtain the photometry of the DRL. This zone 43 is advantageously made of extra thickness with blasting.
- the concave reflector 32 is extended by a base 35 in which an orifice 36 is machined.
- the light-emitting diode 33 mounted on its support 34, passes through the orifice 36 so that its radiation hits the concave reflector 32.
- the peripheral portion 42 which connects the front flange 45 to the convex central portion 43 - said connecting zone 42L corresponding to the concave zone 22C of the previous example - has a conical shape 42K which ends with a concave shape 42C.
- the central convex portion 43 which serves as a collimator radiation from the light emitting diode 33, meets the conditions of said regulation 26.
- a sphere 100 mm in diameter bearing on the flange 45 would not touch element outside, in particular this convex central portion 43 sufficiently recessed with respect to the front position FR (in dashed lines).
- the lighting device 1 ' may belong to a set of DRL daytime running lights.
- FIG. 3 represents the longitudinal sectional view of this assembly along the plane Q of FIG. 3.
- five lighting devices of the type described above - each having a plurality of light emitting diodes - succeed each other adjacent to each other, to form a set 1 "DRL type.
