Optical assembly of a variable traffic sign and variable message signs

摘要

The invention relates, inter alia, to an optical assembly for a display field, in particular display field of a traffic sign or a variable traffic sign, with a lens (10) and a row of at least two or three, in particular different colored, light sources (14.1, 14.2, 14.3), in particular a light emitting diode (LED) (14), wherein the light sources (14.1, 14.2, 14.3) are arranged linearly next to each other at constant intervals along an axis (24), each light source (14.1, 14.2, 14.3) each having an optical axis (15.1, 15.2, 15.3) and the optical axes (15.1, 15.2, 15.3) of the light sources (14.1, 14.2, 14.3) are arranged parallel to each other and in a plane, and wherein the lens (10) for the light sources (14.1, 14.2, 14.3 ) is spaced from the light sources (14.1, 14.2, 14.3), the lens (10) facing one of the row of light sources (14.1, 14.2, 14.3) The light inlet side (12) and with a with the light sources (14.1, 14.2, 14.3) remote light exit side (16) is formed, wherein the light entry side (12) of the lens (10) with a conical collecting optics for the of the light sources (14.1, 14.2, 14.3) of the series emitted light is formed and wherein the collecting optics in the region of its apex a crest line (20), so that the collection optics has a focus line (21), or wherein the collection optics in the region of its apex several juxtaposed, preferably the same height , Vertexes (26.1, 26.2, 26.3), so that the collection optics with the adjacent vertex points (26.1, 26.2, 26.3) each for a light source (14.1, 14.2, 14.3) has a focus (30.1, 30.2, 30.3).
