Variable multisource lighting device
A variable multi-source lighting device is provided on both sides of the front part of a motor vehicle to illuminate both sides and/or only one side of the vehicle when driving in a curve. Activation may be determined by the steering wheel or a GPS signal. In use, the device forms a composite light beam composed of partial light beams from individual light sources. Some of the partial light beams are obliquely oriented relative to the vehicle's longitudinal axis and at least one partial light beam is generally parallel to the longitudinal axis. Depending on the vehicle's speed and/or the position of the steering wheel, the sources may be activated individually, in groups, progressively, discretely or continuously so as to increase or decrease the lateral dispersion of light.
1 . A variable multi-source lighting device positioned on both sides of a front part of a motor vehicle comprising a plurality of individual light sources, each of said individual light sources defining a partial light beam and said partial light beams cooperatively defining a composite light beam from said device, at least one of said partial light beams being generally parallel to the longitudinal axis of the motor vehicle, at least two of said partial light beams being progressively oriented in relation to the longitudinal axis of the motor vehicle at increasing angular orientations thereto, means for actuating said individual light sources on both sides of the motor vehicle with front lights of the motor vehicle and on only one side of the motor vehicle when the motor vehicle is turning along a curved vehicle path.
2 . The device of claim 1 wherein said means for actuating said individual light sources includes steering wheel angle of rotation sensor.
3 . The device of claim 1 wherein said means for actuating said individual light sources includes a global position satellite (GPS) device.
4 . The device of claim 1 wherein said means for actuating said individual light sources is variable depending on the instantaneous speed of the motor vehicle such that with decreasing speed a greater number of said individual light sources are activated.
5 . The device of claim 1 wherein said means for actuating said individual light sources is variable such that with an increasing angle of rotation of the steering wheel a greater number of said individual light sources are activated.
6 . The device of claim 5 wherein said means for actuating said individual light sources progressively activates said individual light sources based upon said angular orientation of said partial light beam of said individual light sources.
7 . The device according to claim 1 wherein said device includes a plurality of chambers in which are located one said individual light sources
8 . The device according to claim 1 wherein said device collectively includes a definitive number of separate devices.
9 . The device according to claim 1 wherein means for actuating said individual light sources activates said individual light sources individually.
10 . The device according to claim 1 wherein said means for actuating said individual light sources activates said individual light sources in groups.
11 . The device according to claim 1 wherein said individual light sources are halogen bulbs.
12 . The device according to claim 1 wherein said individual light sources are xenon bulbs.
13 . The device according to claim 1 wherein said individual light sources are light emitting diodes.
14 . The device according to claim 1 wherein said means for actuating said individual light sources activates said individual light sources in a discrete fashion.
15 . The device according to claim 1 wherein said means for actuating said individual light sources activates said individual light sources in a continuous fashion.
16 . The device according to claim 15 wherein said means for activating said individual light source includes an electronic controller.
17 . The device according to claim 1 wherein said means for activating said individual light sources defaults to the conditions for activation of a fog headlight.
18 . The device according to claim 1 wherein an envelope of said device has a shape of a circle, an ellipse, a rectangle or a square.
19 . A variable multi-source lighting device located on the front end of the motor vehicle, said lighting device comprising a plurality of adjacent chambers, each of said chambers being defined by a reflector and having light source located therein, one of said chambers defining a first optical axis, remaining one of said chambers defining optical axes obliquely oriented with respect to said first optical axis, at least two of said remaining ones of said optical axes being obliquely oriented with regard to said first optical axis at different angles from one another.
