Abstract (en)
[origin: WO2011104206A1] The invention relates to a symbol indicator, in particular for rail-bound traffic routes, comprising LED modules (1) for the pixelated far and near field representation of the symbol, and optical elements which are associated with the LED modules (1) which are arranged on a front plate (3). The aim of the invention is to produce different symbols using only a few optical and mechanical elements and to effectively protect against incident extraneous light on said indicator, such that the LED modules (1) respectively comprise an LED (2) and that the optical elements are embodied as collimator lenses (4) having a first spherical surface for the far field representation of the indicator and a second spherical surface for the near field representation of the indicator. The entire surface of the front plate (3) is provided with collimator lenses (4) and symbol-specific required pixels are produced by the LED modules (1).
