Description

[0006] Below several embodiments of the present invention are provides and described further.

[0007] According to one embodiment of the present invention, the light unit comprises several LED lights, preferably more than 5 LED lights, most preferably 8-10 LED lights. LED lights are of interest as these provides a high visibility and at the same time is simple to mount onto a rear window or unit thereon.

[0008] According to yet another embodiment of the present invention, preferably the light unit comprises several LED units mounted in a row on the rear wiper arm of the vehicle, more preferably comprising more than 5 LED lights, most preferably comprising 8-10 LED lights. To use the wiper arm as the basis for mounting the light units, preferably LED light units, has the advantages that it is a simple integration and provides clear visibility for a vehicle approaching another one, when the hazard warning system according to the present invention is activated. In this regard it should also be said that, according to one specific embodiment the rear wiper arm is arranged to be activated when the light units are activated by the on/off unit. This implies that the rear wiper arm also wipes when the warning light units are activated.

[0009] According to yet another embodiment, the on/off unit is a hazard flasher on/off unit. This implies that the regular hazard flasher on/off unit, e.g. in a car, is intended as the activator also for the light unit of the hazard flasher and warning unit according to the present invention.

[0010] According to yet another specific embodiment of the present invention, said light unit is arranged to provide flashing light when activated, preferably orange flashing light when activated. Also this embodiment is thought as a complement to the existing warning systems used today. It should be noted that also clear illumination without flashing is possible according to the present invention.

[0011] The present invention also provides a hazard flasher and warning unit intended for a vehicle, said hazard flasher and warning unit being complemented with an extra light unit mounted on the rear wiper arm of the vehicle, preferably wherein the light unit comprises several LED units mounted in a row on the rear wiper arm of the vehicle.

[0012] As mentioned above, according to one embodiment, the light unit comprises more than 5 LED lights, more preferably comprises 8-10 LED lights. Furthermore, suitably light units are arranged to provide flashing light when activated, preferably orange flashing light when activated. As mentioned above, flashing lights are one possibility according to the present invention, clear illumination is another one. Moreover, and as also said above, according to yet another specific embodiment of the present invention the rear wiper arm is arranged to be activated when the light units are activated by the on/off unit.

[0013] Furthermore, according to yet another specific embodiment, the hazard flasher and warning unit is arranged to be activated simultaneously as the flashers of the vehicle, such as the four flashers of a car or bus.

[0014] The activation of the hazard flasher and warning unit according to the present invention may be established by use of different techniques. As should be understood from above, this may be performed totally by use of the existing system in a car or bus and then the light unit is only added as one extra unit to be activated when activating the on/off unit. Other possible solutions involve wireless transmission. Moreover, standard LED units are possible to use, however the colour of the light used should be adapted for vehicles and standards used in vehicles.

[0015] Below there are shown one embodiment according to the present invention. In this case, and as seen, LED lights are provided in a row on the rear wiper arm. The hazard on/off unit is activated implying that the system according to the present invention is activated. The activation ensures that rear blinker lights are flashing while the rear wiper arm has illuminated LED lights, flashing or not, at the same time. Moreover, as seen when comparing FIGS. 1 and 2, the rear wiper arm is wiping back and forth.

[0016] In FIGS. 1 and 2 there are shown one embodiment of the present invention. The vehicle 10 comprises a hazard flasher and warning unit 1, wherein the hazard flasher and warning unit 1 comprising an on/off unit connected to a light unit 2 which is mounted on a rear wiper arm 3 of the vehicle 10.
