[0018] FIG. 2 shows a side-view of a vehicle with the lighting device according to the invention.

[0019] FIG. 3 shows a frontal-view of the lighting device.

[0020] FIG. 4 shows a rear-view of the lighting device.

[0021] FIG. 5 shows a second embodiment of the lighting device.

[0022] FIG. 6 shows a third embodiment of the lighting device.

[0023] FIG. 7 shows a lighting device which has been integrated with an inner rear-view minor.

[0024] FIG. 8 shows the lighting device diagonally from below according to FIG. 7.

[0025] With reference to the figures, a lighting device 1 is shown in accordance with the present invention. The lighting device essentially consists of at least one lighting unit 2 which is designed to be temporarily mounted in a vehicle 4 by at least one fastening device 5 on the inside of a windshield 3. The fastening device can preferably be comprised of a design consisting of suction cups 6. Alternatively, a completely different means of attachment that is suitable for the purpose can be used. The suction cups 6 can be connected to a pump, for example a vacuum pump (not shown in the figures) which creates a continuous under-pressure in the suction cups. This continuous under-pressure will keep the lighting unit attached to the windshield. Alternatively, the whole lighting unit can be subjected to under-pressure by a vacuum pump, at which the suction cups can completely or partly be removed.

[0026] The placement of lighting units (lighting unit) is not limited to those shown in FIG. 1, and the lighting units (lighting unit) can essentially be mounted anywhere on the inside of the windshield.

[0027] In order to stop light from entering the interior of the vehicle from between the lighting unit and the windshield, the lighting unit is equipped with at least one seal 7. The seal is preferably made of a rubber list or the like. Alternatively, the seal can be made of some other type of seal that is suitable for the purpose and keeps the light from escaping out from between the windshield and the lighting unit.

[0028] The lighting unit 4 consists of at least one reflector 8. The reflector consists of at least one lamp holder and at least one lamp 9 and to this the accompanying components for mounting and connecting to electric power. The lamp that emits visible light is preferably a Xenon lamp of HID type. Even other types of lamps can be used, as for example Halogen lamps and LEDs (light emitting diodes). In FIG. 2 a design is shown consisting of two reflectors with rectangular shapes. The shape of the reflectors can alternatively be circular, square or other for the purpose suitable shape. In FIGS. 3 and 4 are shown alternative embodiments of lighting units. Xenon lamps have the advantage of not giving off the same amount of heat that traditional driving light lamps of Halogen type do. A type of lamp such as the Xenon HID and even the LED (light emitting diode) has the advantage of lower energy consumption compared with traditional lamps.

[0029] The lighting unit consists of functions with which the emitted light's illumination and direction (position) can be adjusted. Adjustment of the illumination's direction (position) can preferably be accomplished with the aid of adjusting screws that angle the reflector in height as well as sideways. Alternatively, control of the illumination's direction (position) can be accomplished with the aid of electric motors that are designed to adjust the reflectors position in height as well as sideways. FIG. 8 shows a variant where the characteristics and direction of the illumination are controlled with a thumb wheel.

[0030] The emitted light's illumination can even be adjusted in width,'height and length. The method allows the emitted light's illumination to be changed from full high-beam illumination to distance light illumination and vice versa. The illumination's adjustability is accomplished by at least one added disc which refracts the light in such a way that the desired illumination is achieved. Alternatively, the illumination can be adjusted by changing the reflector's shape. Changing the reflector's shape can be accomplished in several ways and preferably with the aid of adjusting screws. The figures' show a maneuvering unit 10 consisting of a knob for adjusting and modifying the illumination.

[0031] The lighting unit is powered by electrical energy feed preferably through at least one cord (not shown in the figures) from at least one outlet (not shown in the figures). One end of the cord is connected to the lighting unit in the usual manner with the aid of previously and generally known and accepted techniques, and therefore this connection is not described further. The cord in its other end is equipped with a contact plug which can preferably be inserted into the vehicle's cigarette lighter. Alternatively, the outlet can be of another type. Alternatively, the lighting unit can be powered by some type of incorporated battery that can emit accumulated energy. It is even conceivable that the lighting unit could hold a unit that generates electric power.

[0032] In order to maneuver the on and off switch of the lighting unit, it is equipped with an on and off switch. The on and off switch is controlled with the aid of at least one sensor that sends control signals wirelessly from the sensor to a receiver in the lighting unit. The sensor can preferably be comprised of a sensor that detects (indicates) if the high-beams are on or off. This can be accomplished by the sensor detecting the light from the high-beam lamp on the instrument panel. The sensor can even be designed to detect the specific positions of the switch (lever) for low and high-beams if the switch (lever) has different positions for low and high-beams.

[0033] Alternatively, the sensor can be designed to detect measurements of electric energy being conveyed to the switched on high-beams. The wireless transmission of information can preferably be comprised of radio signals, for example Bluetooth, which is a standardized method for the transmission of information between units over. short distances. Even other types of radio communication can be utilized. Alternatively, the transmission can he accomplished by signals sent via infra-red light (IR).

[0034] The design can even consist of a sensor that detects the light from surrounding vehicles at which the driving light automatically shuts off. Preferably, the light emitted from oncoming traffic and vehicles directly ahead. Alternatively, it is thinkable that radar, IR-sensors or other types of sensors suitable for the purpose can be used to indicate oncoming or nearing vehicles. The design can even consist of an automatic illumination control that is affected by the turning of the steering wheel. This automatic control means that the illumination moves toward the left during a left turn and in a corresponding way the automatic control results in the illumination turning to the right during a right turn. The position of the steering wheel is detected by a sensor that wirelessly transmits the information (control signals) to the lighting unit. The lighting unit consists of a receiver that receives the signals from the sensor. The receiver sends the signals to a control system that in its turn directs the electric motors to move the reflector.

[0035] Xenon lamps such as the Xenon HID lamp are an excellent variety of lamp that however has the disadvantage of not emitting light at full strength directly after it has been switched on. Full-strength illumination can take a few seconds. In order to provide full-strength illumination when the lighting unit is turned on, the lighting unit can be equipped with a shutter (not shown in the figures) of the type used for cameras and the like, which stops the light from being emitted from the lighting unit. Alternatively, some other kind of shutter suitable for the purpose can be used. By using a shutter function the lamp can be turned on at all times thereby eliminating the mentioned problem.

[0036] In FIGS. 5 and 6 examples of alternative embodiments of the lighting units are shown. The lighting unit in FIG. 5 is equipped with two round reflectors. The lighting unit in FIG. 6 is equipped with two relatively larger round reflectors with a relatively smaller intermediate round reflector.

[0037] In FIGS. 7 and 8 an alternative embodiment of the lighting device 1 is shown mounted on the inside of a windshield 3, which is designed to be integrated with or placed in direct proximity to the rear-view mirror 11. The lighting device 1 consists of a lighting unit 2 which consists of at least two reflectors 8 and at least two lamps 9. The lighting unit's 2 casing 12 consists of at least one recess 13 or the like that allows the lighting unit to completely or partially encompass the rear-view mirror's 11 fastener 14. The characteristics and the direction of the illumination are controlled by the thumb screw 15. In variations of the lighting unit 1 it is thinkable that the rear-view mirror is directly mounted on the lighting unit 2 without a fastener 14. The fastening device 5 in this embodiment is preferably comprised of a double-sided tape or other for the purpose suitable attachment device. Because the lighting unit 2 completely or partially encompasses the rear-view mirror's 11 fastener 14, blockage of the driver's line of sight (visibility) by the lighting device is minimized.

[0038] These embodiments of the present invention have been developed to avoid any possible problems with visibility and also the vehicle's preinstalled safety equipment (airbags and the like) which in certain vehicle types are found in close proximity to the windshield, as well as any displays designed to show information on the windshield. The figure shows clearly that the invention's impact on traffic safety (driver visibility), safety equipment and possible information displays is negligible. The purpose of the invention is to improve traffic flow and traffic safety when vehicles are used in traffic and not to reduce safety for the driver, the passengers, other vehicles or pedestrians.

[0039] Several advantages are achieved thanks to the invention. For instance the driving light can easily be moved from one vehicle to another. Furthermore the invention makes it possible to mount driving lights on vehicle models where earlier it was difficult if not impossible to mount driving lights. Another advantage with the invention is that it reduces the risk of the driving light theft. Further, the driving light is to a minimal extent exposed to dirt and grime which has the positive effect that the emitted light from the lighting unit is essentially not reduced. The present invention also achieves the advantage of the driving light being placed high up as well as being able to adjust the illumination without having to remove the driving light. Further, the environmental disadvantages mentioned earlier are eliminated and even the traffic safety disadvantages with externally mounted driving lights are eliminated. Even if certain preferred embodiments have been described in detail, variations and modifications can within the scope of the invention become evident for specialists in the field and all such are regarded as falling within the scope of the following claims.
