Light signal
A light signal, in particular for rail-bound traffic routes, includes a control device which controls a light source, and an optical system for visualizing a signal term. In order to more precisely adjust brightness boundaries, light distribution and phantom light intensity, a transmission-controllable smart-glass element is provided in an aperture segment of the light flow.
1. A light signal, comprising:
a light source producing a light flow;
a control device controlling said light source;
an optical system for visualizing a signal term; and
a transmission-controllable smart-glass element provided in an aperture segment of the light flow, said smart-glass element disposed in said aperture segment including a plurality of separate, transmission-adjustable, smart-glass discs.
2. The light signal according to claim 1 , wherein said smart-glass element is disposed between said light source and said optical system.
3. The light signal according to claim 1 , wherein said control device is configured to set a transmission of said smart-glass element.
4. The light signal according to claim 1 , which further comprises at least one ambient light sensor connected to said control device.
5. The light signal according to claim 1 , wherein said smart-glass discs are circular-segment-shaped.
6. The light signal according to claim 1 , wherein said smart-glass element projects into the light flow.
7. The light signal according to claim 6 , wherein said smart-glass element projects into one part of the light flow.
8. The light signal according to claim 1 , wherein said smart-glass element is one of a plurality of smart-glass elements projecting to varying degrees into the light flow.
9. The light signal according to claim 1 , wherein the light signal is configured to be disposed along a rail-bound traffic route.
