Light arrangement for use in road lighting to illuminate ground, has light sources coupling light above front sides in optical fiber, which is impinged with elastic force acting between fiber and support in direction perpendicular to sides

摘要

The arrangement has an optical fiber (20) i.e. solid optical fiber, including two oppositely lying front sides, at which the optical fiber is connected with a support (1) by holding devices (22, 24). The optical fiber is displaceably mounted in one of the holding devices in a direction perpendicular to the sides. Light sources i.e. red, blue, green LEDs, are provided in one of the holding devices, and couple light above the front sides in the fiber. The optical fiber is impinged with elastic force acting between the fiber and the support in the direction.
