Description

VEHICLE LIGHTING ASSEMBLY, VEHICLES :2 :2 3 El -1 0 D PARTICULARLY FOR
MOTOR The present invention relates to a vehicle lighting assembly, particularly for motor vehicles.
The term "lighting assembly" is intended to mean any assembly for emitting at least one light signal for indication or lighting purposes.
Vehicle lighting assemblies are known to comprise a supporting body housing a number of lights, each having a respective light source usually consisting of an incandescent lamp. As the lamps employed on such assemblies absorb current of a few amperes, they must be connected to a supply device, usually a battery, over electric cables, the section and cost of which is far from negligible. Moreover, on account of the volume of the lamps and the heat emitted by the same, the lighting assembly itself is relatively large. Finally, being designed to enable both replacement of the lamps and removal of the condensate invariably produced by sharp changes in temperature, lighting assemblies of the aforementioned type are never perfectly airtight, and 1 are thus subjected to external agents resulting in relatively rapid oxidation of the electric circuit components supplying the lamps and in damage to the reflecting components inside the lights.
The aim of the present invention is to provide a lighting assembly designed to overcome the aforementioned drawbacks.
With this aim in view, according to the present invention, there is provided a vehicle lighting assembly, particularly for motor vehicles, comprising at least one light and at least one light source located inside said light, characterised by the fact that it also comprises a primary light source located outside said light; said internal light source being a secondary light source dependant on said primary light source; light conveying means being provided between said primary and secondary sources, and shutter means being connected to said conveying means for controlling the emission of a light signal by said secondary source as a consequence of the emission of a corresponding light signal by said primary source.
Said conveying means on the above lighting assembly preferably consist of an optical fiber bundle, and said shutter means comprise an optoelectronic shutter which may be formed to advantage using liquid crystals.
A preferred non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
Fig.1 shows a schematic view of a lighting assembly in accordance with the teachings of the present inventA rn; Fig.2 shows a larger-scale section of a detail in Fig.1; Fig.3 shows a section of a variation of the Fig.2 detail.
Number 1 in Fig.1 indicates a vehicle lighting assembly comprising a casing 2 housing three lights 3 (conveniently the parking, stop and direction indicator lights of a motor vehicle), each housing a light source 4. Lighting assembly 1 also comprises a primary light source 5 for emitting a light signal which is supplied to each light 3 via a respective light conveyor consisting of an optical fiber bundle 6. Said bundle 6 presents one end facing primary source 5, and the other end inside respective light 3 and constituting said source 4 hereinafter referred to as the "secondary source."
Each bundle 6 is connected to an optoelectronic shutter 7 for controlling the flow, along bundle 6. of the light signal emitted by primary source 5.
In the example shown, said shutter 7 is a liquid crystal type.
Primary source 5 comprises a lamp 8, preferably a halogen lamp, and a reflector 9 located behind lamp 8 for directing the rays produced by the same on to a concentrating element 10. This forms part of primary source 5, and comprises a sphere of transparent material, preferably glass, located on the opposite side of lamp 8 to reflector 9. The light signal rays emitted by 1 8 are received by element 10 via a filtel,- 11 impervious to infrared rays, and are concentrated by element 10 on to the input ends 12 of bundles 6, each of which conveys the incoming rays to its output end located, as stated, inside respective light 3 and constituting said respective secondary light source 4.
Each light 3 comprises a reflector 13 and a diffusor 14 located inside light 3 for receiving the rays from secondary source 4 both directly and by reflection, and so diffusing the same as to produce an output beam of given width. Each light 3 also comprises a transparent element 15, usually common to all of lights 3, located in front of the opening of reflector 13 for closing casing 2, and having a prism portion 16 usually acting as a Fresnel lens.
In Fig.1, each shutter 7 is shown, for the sake of simplicity, as being located between two adjacent in-line portions of bundle 6. In actual fact, each shutter 7 is preferably located as shown in Fig.2, i.e. between respective secondary source 4 and diffusor 14.
As shown in Fig.2. each shutter 7 comprises a liquid crystal plate 17 provided with an electronic control circuit 17a having two input terminals 18, of which one is grounded and the other connected to a respective line 19 of an electric supply circuit 20. Circuit 17a also presents two output terminals connected to respective input terminals on plate 17, and converts the voltage at a.
terminals 18 into an alternating electric signal for controlling the transparency of plate 17.
The liquid crystals of plate 17 are preferably oriented in such a manner as to respectively render plate 17 impervious to light rays or transparent in the absence or presence of a given voltage at terminals 18.
Finally, plate 17 may comprise two superimposed liquid crystal plates (not shown) arranged perpendicular to each other.
As shown in Fig.1, lines 19 are branch connected to respective parallel lines 21 connected, at one end, to a pole of a voltage source 22, usually a battery, via respective switches 23, and, at the other end. to a common node 24 via respective disconnecting diodes 25, each located between node 24 and respective line 19. Node 24 is connected to a first supply terminal 26 of lamp 8, the second terminal 27 of which is grounded.
As shown in Fig.1, closure of any one of switches 23 operates primary source 5 and results in the emission of light visible externally via respective secondary source 4. If said switch 23 is operated intermittently, the light visible externally via respective secondary source 4 will also be emitted intermittently, which intermittence is controlled by respective switch 23 via respective shutter 7, regardless of whether primary source 5 is intermittent or emits a steady light as a result of a further switch 23 being closed simultaneously.
A One of lights 3 may also be operated intermittently using a special type of circuit 17a, which provideQ-for alternately rendering plate 17 transparent and impervious to light.
In the Fig.2 embodiment, diffusor 14 comprises a concave mirror 28 located on the opposite side of plate 17 to secondary source 4, and designed to receive the rays emitted by secondary source 4 and reflect the same on to the surface of reflector 13.
In the Fig.3 variation, mirror 28 is replaced by a lens 29, the surface of which opposite the one facing plate 17 is concave. In this case, reflector 13 may be dispensed with.
In addition to enabling numerous differently and independently operated lights 3 to be connected to a single primary light source 5, the present invention clearly also provides for locating primary source 5 independently of lights 3 and, in particular, in a position close to voltage source 22, affording full protection against external pollutants and oxidizing agents, and enabling fast, troublefree replacement of primary source 5.
Moreover. by eliminating the need to replace source 4 inside each light 3, which, being a passive source, presents practically no limit to its working life and emits substantially no heat by virtue of filter 11, each light 3 may be made perfectly airtight for preserving reflector 13 (if any) for relatively long periods of q1 4 time.
Lights 3 may obviously differ in number and funcúion from those described herein. For example, assembly 1 may comprise a single headlight or a pair of front headlights.
Each light 3 may also be connected to a number of bundles 6 for improving diffusion of the secondary source or producing a number of separate secondary sources.
Finally, circuit 20 in Fig.1 is only one of the many circuits designable by a technician of average ability for supplying primary source 5 and controlling shutters 7 as required.
