Definitions
- the present invention relates to a warning or signaling light which may for example equip special vehicles such as a police vehicle or a service vehicle or sanitary and relate to any type of land, air and sea traffic.
- the luminous signage has progressed a lot in terms of consumption and lighting efficiency.
- a technique currently in rapid development involves the use of light emitting diodes (LEDs) whose emitted light is, at equivalent power, much less energy-consuming and whose lifetime is greatly increased than that of incandescent light sources.
- LEDs light emitting diodes
- these diodes are in battery on a support and their ignition is sequential or fixed depending on the nature and content of the message to be displayed.
- a rotating signal for example a beacon
- the most used means is to rotate a mirror by which beams, shaped by light reflectors of the diodes, are reflected in a horizontal plane.
- Document US 2007 263376 illustrates an apparatus of this kind.
- the present invention intends to remedy these drawbacks by proposing a static device in which the light-emitting diodes are distributed in a circle and fed sequentially and in time and space, so as to simulate a rotation or all together or by angular sector to simulate warning flashes.
- the subject of the invention is therefore a warning lamp comprising a base base defining an annular supporting ring of a plurality of light-emitting diodes regularly distributed over this ring, each diode being associated with a substantially oriented rear reflector. radially outward and to an optics before crossing the direct and reflected beam.
- the annular support ring of the diodes is frustoconical with its large base facing upwards, in that the reflectors are borne by a single piece having a base plane above which extends each reflector formed by a surface reflective dish-shaped of revolution whose focus is located in the base plane, and in that the optics is carried by a single piece in the form of a cabochon on the base and whose side wall is a horizontal diffuser.
- This warning light has the advantage of an extremely simple constitution, based on a small number of components, namely a support, a shaped part comprising all the reflectors and a transparent cabochon for the main ones.
- the light-emitting diodes are integral with a totally assembled integrated circuit which rests on the annular support and a radiator can also be put in place under the support of the diodes, inside the annular support. Fixing the mirrors on the support is then extremely simple, in particular by a few vertical screws.
- the center of each light-emitting diode is offset relative to the focal point of the associated reflector so that the reflected beam is diverging around its mean direction parallel to said plane.
- This offset may be either at the focus but above the base plane, or in this base plane, on the axis of the reflecting surface, towards the top of this surface.
- the divergence can be obtained by a reflector whose profile does not quite correspond to a paraboloid of revolution, so that for a position of the diode at the focus of this pseudo paraboloid, still get the required divergence in the vertical plane.
- the horizontal diffusion power of the cabochon shall be such that two consecutive lit diodes emit a substantially uniform flattened beam and diverge about 110 degrees in a plane parallel to the base plane of the reflective piece from the axis of revolution of fire.
- FIG. 1 illustrates, by axial section, a warning light according to the invention
- FIG. 2 is a detail view of the device of Figure 1, the cover cap having been removed.
- the warning light apparatus 1 shown comprises a base base 2, substantially cylindrical by its outer surface and defining an annular ring 2a for supporting an equally annular support plate 3.
- electroluminescent diodes 4 and the electronic circuit of their power supply are, in the example shown, the number of eight. They are therefore regularly spaced at an angle of 45 degrees. Fixing the plate 3 on the support 2 is carried out by any known means, for example by gluing.
- the annular ring 2a of the support 2 is frustoconical with its large base facing upwards.
- the plate 3 (which can be in several adjacent parts) so that the diodes are inclined towards the center of the device.
- the outer circle 3a of the support 3 (or the large base of the support 2) forms the lower limit of the opening through which the direct and reflected beam radiated by the diodes.
- the apparatus comprises a part 5 which carries a reflector mirror for each diode 4. It is for each diode, in the example shown, a kind of shell 5a which cap each diode and whose concave surface P is reflective. In the case shown, the surface is substantially in the form of a half paraboloid whose focal point F is in the base plane 5b of the part 5, plane through which the reflecting piece 5 is fixed to the base 2 (pads 5c and 2a pads of the base ).
- each diode is located vertically above the focus F above.
- This offset E allows the mirror to reflect a divergent radiation in the vertical plane as illustrated by the radii R1, R2 drawn in Figure 2.
- the divergence angle D will be of the order of 4 degrees upwards and 4 degrees downwards relative to a direction H corresponding to the axis of the surface of the paraboloid P.
- the adjustment in altitude of the position of the reflector 5 with respect to the level of the diodes, and therefore with respect to the base 2 is a means of adjustment of this divergence. In a variant not shown, this divergence is obtained if the center 4a of the diode 4 is placed on the axis of the surface but offset from the focus F along this axis towards the top of the reflecting surface.
- each flag 5a is in intersection I with the adjacent flags.
- This geometry results from the opening chosen for the paraboloid in order to obtain a significant and standardized height of the beam while keeping the smallest possible diameter for the apparatus.
- the fire according to the invention further comprises a outer cabochon 6, transparent material, which tightly closures the device (seal 6a) and which has a side wall 6b shaped as a horizontal diffuser by a succession of vertical streaks 6c.
- this diffuser The role of this diffuser is to mix the radiation of two adjacent diodes in a horizontal plane (when the axis A is vertical) so that the beam from the device has the shape of a light brush of substantially constant thickness about 110 degrees of angle centered on the bisector of the angle separating the two consecutive diodes lit.
- the warning light according to the invention is a multi-function device.
- the lighting of the diodes is programmed in a sequential manner: two adjacent diodes are lit then one is off at the same time as the other diodes adjacent to the one that remains lit is lit and so on, keeping at each diode the same ignition time.
