US 2024/0194064 A1 · LIGHTING SYSTEM FOR ROAD CROSSING, MAINLY FOR PEDESTRIAN CROSSWALKS, METHOD OF LIGHTING

Abstract

The system includes at least one light projector designed for focused projection of the image onto the surface of the road crossing. The light projector is connected with the control unit and is designed for projection of various images onto the persons and road in the place of crossing. The image from the light projector includes circles, polygons, strips, squares, rectangles, and combinations thereof, which are separated by surfaces of different color or different level of illumination. There are sharp, contrasting boundaries between individual, usually repeating elements of the image. In the preferable arrangement the system includes at least one sensor of the physical values of the environment connected to the control unit and eventually a camera and/or vehicle speed sensor and/or sensor of physiological values of the persons in the vicinity of the road crossing, too. The system can include a speaker connected to the control unit.

Dependent claims

A system of lighting of road crossings, mainly pedestrian crosswalks, the system comprising:

at least one lighting body and sensors (3) for detecting a presence of persons on both sides of the road crossing,
sensors (9) of vehicles approaching the road crossing, wherein the sensors (3) of the presence of the persons and the sensors (9) of the vehicles (9) are connected with a control of the lighting body, is characterized by the fact, that
wherein each one of the lighting body is formed by a light projector (2) whose light field is directed onto the road crossing,
wherein the light projector (2) is designed for a projection of various images onto the persons and the vehicles in a place of the road crossing,
wherein the light projector (2) is equipped by a device for a decreasing of an intensity of an illumination of at least part of an illuminated surface where the vehicle is present, ad
wherein the light projector (2) is connected to a control unit (1) for a control of the lighting and for the control of the decreasing of the intensity of the illumination in the place of the vehicle.
