Illumination device for selectively emitting light along a traffic direction or in a direction opposite to the traffic direction, and a method for controlling the illumination device

摘要

The present invention proposes a lighting device 250. The lighting device 250 for road lighting is a lighting module and a control module coupled to the lighting module, and a first lighting pattern B on the road surface when a first predetermined condition is satisfied. Control the illumination module to emit a first light beam 221 in a first direction to generate a second illumination pattern A on the road surface when a second predetermined condition is met And a control module configured to control the illumination module to emit a second light beam 231 toward a second direction, the first direction being directed to travel along a traffic direction. The second direction is oriented to travel in a direction opposite to the direction of travel.
