Hazard beacon

摘要

An apparatus including at least one Light Emitting Diodes (LEDs) mounted on a platform; a mechanism for controlling the at least one LEDs; and at least one refractive optic lenses for focusing at least one light beam from the at least one LEDs into at least one well-defined light beams and for directing the at least one well-defined light beams either in an upward direction or in a sideward direction to the platform. In one example, the platform is a vehicle.

主权项

1. A warning system comprising:
a first hazard beacon and a second hazard beacon that are mounted on a vehicle that is blocked from view of approaching traffic by an intervening vehicle; said first hazard beacon defined by at least one Light Emitting Diode (LED) and at least one associated refractive optic lens; said second hazard beacon defined by at least one LED and at least one associated refractive optic lens; a mechanism for controlling the at least one LED of each of said first and second hazard beacons; where the at least one refractive optic lens of the first hazard beacon focuses light from the at least one LED of the first hazard beacon into at least one well-defined light beams with a pattern that has a width greater than 10 degrees and a less than 15 degrees; where the at least one refractive optic lens of the second hazard beacon focuses light from the at least one LED of the second hazard beacon into at least one well-defined light beams with a pattern with a width greater than 10 degrees and a less than 15 degrees; wherein the pattern of the at least one well-defined light beams of the first hazard beacon and the pattern of the at least one well-defined light beams of the second hazard beacon are cast in opposite sideward directions so that the pattern is viewable on the sides of the intervening-vehicle by said approaching traffic; and, wherein the light of the at least one LED is a first preselected color if the accelerator of the vehicle is engaged, a second preselected color if the brake of the vehicle is engaged, or a third preselected color if the vehicle is coasting, wherein the first, second and third preselected colors are different from each other.
