摘要

Set of colimar collimation for the light emitted by a light emitting diode, lighting system and display device. The invention is a set of collimation (1, 2, 3, 4) for colimar light emitted by at least one light emitting diode (12, 14) provisions on A flat base (16).The set of collimation (1, 2, 3, 4) comprising a collimator (20, 22, 24) and a series of reflective surfaces (50, 52).The collimator comprises an entrance window of light (28, 30) to admit the light emitted by a light emitting diode within the collimator (20, 22, 24), a light exit window (32, 34) to emit the light from the collimator (20, 22, 24), and comprises a first superfu00edci And the edge (36), a second surface of the edge (38), a third edge surface (40, 42,44) and a fourth surface of the edge (46, 48).The set of collimation (1, 2, 3, 4) is provided to guide the light emitted by a light emitting diode (12, 14) in a direction of the third and fourth edge surface (40,42,44,46,4 8) in the direction of the light exit window (32) by total internal reflection. It is expected to To guide the light emitted by a light emitting diode (12),(14) in the direction of the first and second surfaces of the edge (36, 38) through the reflective surfaces (50, 52). This results in a set of collimation, the width (W) of which can be easily reduced.
