Abstract

The device is automatically switched in when a photodetector mounted in the optical path of the normal headlamps indicates that there is insufficient light being emitted while the headlamp activate switch is closed. The emergency light is connected to the vehicle's battery by normally open contacts on a relay. The coil of this relay is supplied through a normally closed contact on a second relay which is energised while the headlamps are working normally. A three position switch allows the emergency lamp to be turned on manually, or automatically by a photoresistor, or to be turned off. The device can be used for motorcycles as well as for motor cars.

Description

La présente invention concerne la sécurité des motocyclistes principalement et, également des automobilistes dans le domaine de léclairage en route par l'allumage automatique, lore de l'extinction accidentelle du ou des phares d'un phare auxiliaire, pouvant 4tre un phare additionnel longue-portée ou anti-brouillard, qui existe sur beaucoup de véhicules. The present invention relates to the safety of motorcyclists mainly and, also of motorists in the field of road lighting by automatic ignition, due to the accidental extinction of the headlight (s) of an auxiliary headlight, which can be an additional long headlight. range or anti-fog, which exists on many vehicles.

Il existe un procédé permettant sur une motocyclette de commu tor automatiquement l'alimentation du filament grillé de l'ampoule du phare dur l'autre filament, par exemple de passer de phare en code gt réciproquement. Le procède est pou efficace, car il ne fonstionne pas si:
Lea deux filaments sont grills
l'alimentation est coupée (fusible, fil)
le phare ou l'ampoule est cassé par un gravier
le système de commutation automatique est détérioré.There is a process allowing a motorbike to automatically switch the supply of the burnt out filament from the headlight bulb to the other filament, for example to switch from headlight to gt code vice versa. The process is effective because it does not work if:
Both filaments are toasted
power is cut (fuse, wire)
the headlight or bulb is broken by gravel
the automatic switching system is damaged.

La présente invention évite ces inconvénients, sauf si la batterie du véhicule est hors service, mais dans cette hypothèse, il n'existe plus de secours possible. The present invention avoids these drawbacks, except if the vehicle battery is out of service, but in this case, there is no more backup possible.

Même ai le dispositif0 objet de l'invention est détruit, le phare auxiliaire s'allume
Le dispositif de cette invention comprend ( planche 1/2, big. 1) une cellule photo-resistante (CPR) éclairée par la lampe du phare (CPV). Un courant, venant de la génératrice du véhicule passant par la cellule exite un relais (A), commandant le relais de puissance (RP). Le mouvement de fermeture-ouverture du relais (A) est obtenu par la variation de la reaistance de la cellule (CPR) en raison inverse de son éclairement.Even if the device object of the invention is destroyed, the auxiliary headlight comes on
The device of this invention comprises (plate 1/2, big. 1) a photoresist cell (CPR) illuminated by the headlight lamp (CPV). A current, coming from the generator of the vehicle passing through the cell exits a relay (A), controlling the power relay (RP). The closing-opening movement of the relay (A) is obtained by the variation of the cell resistance (CPR) in inverse ratio to its illumination.

Le dispositif objet de l'invention, fonctionne do la manière suivante/:
Un inversuer (I) permet trois cas d'utilisation. Dans tous les cas le contact de phare (CP) est ferré.The device which is the subject of the invention operates in the following manner:
A reverse (I) allows three use cases. In all cases the headlight contact (CP) is on.

Inverseur (I) sur (1):
La cellule (CPR) étant éclairèe, le relais (A) est axité et vient an travail (T) Le relais de puissance (RP) est en repos (P), le phare auxtlaire (PLP) est éteint.Inverter (I) on (1):
The cell (CPR) being lit, the relay (A) is oriented and comes to work (T) The power relay (RP) is at rest (P), the auxiliary headlight (PLP) is off.

Si pour n'importe quelle raison, la cellu le n'est plus éclairée elle levient trés resistante, le relais (A) n'est plus exité, il vient en repos (R), exite le relais (RP) qui vient on travail (T) et le phare (PLP) s'allume.  If for any reason, the cell is no longer lit it raises very resistant, the relay (A) is no longer energized, it comes to rest (R), exits the relay (RP) which comes to work (T) and the headlight (PLP) comes on.

Inverseur (1) en (2) :
Conduite avec phare snti-brouillard ou longu-portée.Inverter (1) into (2):
Driving with snti-fog or long-range headlight.

a) Position "phare
Les relais (A) et (B) sont hors circuit, le phare (PLP) est allumé
b) Position "code""
Le relais (3) est éxité et vient en travail (T). Le relais (d), relié de nouveau à la cellule (CPR) ramène le dispositif 8 la situation du cas n 1. En cas de panne du code, la cellule (CPR) dans l'obscurité coupe l'exitation du relais (A) et le phare (BLP) s'allume.a) Headlight position
Relays (A) and (B) are off, the headlight (PLP) is on
b) Position "code""
The relay (3) is exited and comes into work (T). The relay (d), connected again to the cell (CPR) brings the device 8 back to the situation of case n 1. In the event of a code failure, the cell (CPR) in the dark cuts off the excitation of the relay (A ) and the headlight (BLP) comes on.

Inverseur (I) sur (3)
Le relais (A) est toujours exité et le phare (PLP) ne peut plus s'allumer. Cette position s'utilise par exemple, en stationnement.Inverter (I) on (3)
The relay (A) is still on and the headlight (PLP) can no longer turn on. This position is used, for example, when parked.

La résistance (R) limite l'intensité dans la cellule (CPR)
Le dispositif, objet de l'invention, peut être utilisé dans toua les cas où un éclairage permanent est obligatoire. Toutefois il existe une interruption très fable due au mouvement du relais.Resistance (R) limits the intensity in the cell (CPR)
The device which is the subject of the invention can be used in all cases where permanent lighting is compulsory. However there is a very fable interruption due to the movement of the relay.

Ce dispositif peut particulièrement etre utilisé pour l'éclsira- ge, en route de nuit, d'une voiture automobile et surtout pour celui d'une motocyclette qui ne posséda qu'un seul phare. This device can be particularly used for lighting, on the road at night, of a motor car and especially for that of a motorcycle which had only one headlight.

La réalisation se fait sur un circuit imprimé (Pl. 1/2 Fig. 2) portant deux relais miniaturisés et une cellule photo-résistante,
Le dispositif est fixé sur l'optique du phare (Pl. 2) au moyen de pattes.The realization is done on a printed circuit (Pl. 1/2 Fig. 2) carrying two miniaturized relays and a photoresist cell,
The device is fixed to the headlight optics (Pl. 2) by means of lugs.

Un trou de diamètre 5 m/m eu dessus de la lampe laisse passer la lumière du filament de l'ampoule du phare, et éclaire la cellule. A 5 m / m diameter hole above the lamp lets the light from the filament of the headlight bulb pass, and illuminates the cell.

Un conjoncteur enfichable relie le montege au réseau du véhicule ou de l'installation. Cette technique permet un montage et un démontage aisés A plug-in contactor connects the montege to the vehicle or installation network. This technique allows easy assembly and disassembly
