Abstract

Improvements in the lighting apparatus, of the type that allows, by placing in continuous lines, a lighting installation, a road located in a transition zone at the entrance of a long tunnel or in the body of a tunnel and comprising a reflector having at least one real light source, characterized in that said reflector has a middle longitudinal section that has the shape of at least a portion of ellipse whose plane containing it is parallel to the direction of circulation and whose two foci are separated from each other by a distance less than a critical distance that gives rise to flicker for a given speed, so that if only one actual light source is located in one of the foci, a light source is formed in the other focus virtual that prevents flicker.
