Abstract

System device realized by one series of impulse discharge lamps installed along the road that in case of fog illuminate the vehicular path by means of sequence ignition.

Claims

AMENDED CLAIMS [received by the International Bureau on 10 October 2007(10.10.2007)]
Claims
Claim(l)-A system for driving vehicles in the Fog by illuminating the road through light-flashing preceding vehicles themselves comprising:
-a- Installation of floodlights and relevant impulsive discharge lamps raze to the ground with an obliquous angle toward the march direction of vehicles,
-b-Proccssor logic which establish frequency and duration of light —flashing preceding vehicles, according inputs detected by fog-intensity detectors and by vehicles passage detectors installed along the carriageway.
Claini(2)-The system of claim (1) where fog detectors and/or passage detectors are disabled, and the frequency and/or duration of flash-light are set-up manually according a determined security vehicles speed .
Claim(3)-The system of claims(l) and(2) set-up for night rods illumination in absence of fog , for safe driving and energy saving.
