Description
"Procédé pour modifier l'éclairage d'un projecteur et dispositif pour sa mise en oeuvre" .
Si l'on utilise des projecteurs munis d'une lampe 1 filament unique, lampe à iode par exemple, il est nécessaire d'avoir deux projecteurs, l'un pour l'éclairage de croisement,

tion du faisceau de croisement ayant une partie de sa source lu- mineuse masquée par une coupelle.
La présente invention a pour objet un procédé permet- tant d'obtenir à volonté l'éclairage route ou l'éclairage croise- ment avec un projecteur à un seul filament, dans lequel le fais- ceau de croisement est ottenu en Masquant partiellement le fila-

Conformément à l'invention, dans le but d'obtenir, un éclairage croisement-route, à partir du projecteur ci-dessus décrit, les ailettes 9 et 10 sont munies de glissières 11 et 12 qui se prolongent sur la longueur du cache lumière 8 et sont

Les figures 3 et 4 schématisent la répartition du flux lumineux, suivant un éclairage de croisement et route, en fonction du déplacement de la coupelle 13 devant le filament de la lampe 1.

éclairage de croisement (position des figures 1 et 3). On remarque que, dans le but de rabattre les rayons lumineux vers le bas,
(feux de croisement) le filament de la lampe 1 est exfocalisé, par rapport au foyer F de la parabole 3.
Sur la figure 3, le projecteur émet un faisceau de croi-

filament de la lampe 1, afin d'éviter la réflexion totale du faisceau émis.
Au contraire, sur la figure 4, le faisceau lumineux est réfléchi par la totalité du réflecteur 3, la coupelle 13 étant

le champ masqué par l'équipage mobile, une zone parabolique, focalisée sur le filament de la lampe.

"Method for modifying the lighting of a projector and device for its implementation".
If you use headlamps fitted with a single 1-filament lamp, iodine lamp for example, it is necessary to have two headlamps, one for the low beam,
<EMI ID = 1.1>
tion of the dipped beam having part of its light source masked by a cup.
The object of the present invention is a method which makes it possible to obtain road lighting or crossing lighting at will with a single-filament headlamp, in which the crossing beam is removed while partially masking the fila. -
<EMI ID = 2.1>
by translation all or part of said cup, which makes it possible to use the flux emitted in the demarcated part of the lamp to obtain the high beam; it also relates to a projector for the implementation of this method.
<EMI ID = 3.1>
indicative and in no way limiting one embodiment of the present invention.
Figure 1 is a longitudinal sectional view of the dis- <EMI ID = 4.1> Figure 2 is a front view with the lamp and colored bulb removed.
Figures 3 and 4 schematically show the distribution of the light flux, respectively, in the crossing position and in the road position.
<EMI ID = 5.1>
iodine lamp for example, mounted on collar 2 of reflector 3
(only partially shown in figure 1), by the in-
<EMI ID = 6.1>
To meet the lighting standards of certain countries, lamp 1 can be fitted with a colored 7 "bulb attached to the adapter 4 *
In a known manner, the power supply to the lamp is ensured
<EMI ID = 7.1>
lamp*
Towards the front, the cover 8 is extended, so as to
<EMI ID = 8.1> <EMI ID = 9.1>
teens differently.
According to the invention, in order to obtain a crossing-road lighting, from the headlight described above, the fins 9 and 10 are provided with slides 11 and 12 which extend over the length of the light cover 8 and are
<EMI ID = 10.1>
of the cover 8 ... The effects of the transverse displacement of this cup 13 will be described later with the aid of Figures 3 and 4.
<EMI ID = 11.1>
A return spring 20 of the plunger core 16 comes to bear, on the one hand on the crimping of the central core 21 of the electromagnet, on the other hand, on a washer 22, integral with the plunger core 16:
According to another characteristic of the invention, the
<EMI ID = 12.1>
<EMI ID = 13.1>
<EMI ID = 14.1>
number of amperes / revolution of the coil of the electromagnet.
Can it be controlled directly from the use dashboard light switch *?
<EMI ID = 15.1>
Figures 3 and 4 show schematically the distribution of the light flux, according to dipped and road lighting, as a function of the displacement of the cup 13 in front of the filament of the lamp 1.
<EMI ID = 16.1>
crossing lighting (position of figures 1 and 3). We notice that, in order to bend the light rays downwards,
(dipped beam) the filament of the lamp 1 is exfocused, with respect to the focus F of the parabola 3.
In figure 3, the projector emits a cross beam
<EMI ID = 17.1>
filament of the lamp 1, in order to avoid total reflection of the emitted beam.
On the contrary, in FIG. 4, the light beam is reflected by the whole of the reflector 3, the cup 13 being
<EMI ID = 18.1>
the field masked by the mobile equipment, a parabolic zone, focused on the filament of the lamp.
The invention described above has many advantages and in particular
<EMI ID = 19.1>
Vehicles already on the market which are fitted with only two conventional lighting projectors.
<EMI ID = 20.1>
Mobile, which facilitates its realization.
The return spring of the plunger core allows, in case
<EMI ID = 21.1> It is understood that the invention is not limited to the embodiment described above and that others can be used without departing from the scope of the invention. One can for example retract the cup, still in translation, by moving it obliquely, with respect to the axis of the projector, by
