Title: System for amplifying the visibility of light signals
Inventor: GALATANU CATALIN DANIEL
IPC: B60J3/06
Filed: 1997-09-17
Abstract: The invention refers to an amplification system for light signal visibility intended for railway vehicles, whose goal is to increase the visibility level of light signals. This amplification is achieved by decreasing the luminance of the background, while the luminance of the visual load is kept as high as possible from the technical point of view. According to the invention, the amplification system, based on stroboscopic glasses (3) for the vehicle operator (2) and a synchronisation unit (4), whose performance is synchronised with the emission of light signals, uses an intermittent light source (1), which function with impulses at a natural and autonomous frequency, with respect to which the synchronisation unit (4) adjusts itself in phase with a light flux (ls) emitted by the light source (1), by using a clock signal, received by antenna (5) or by means of a contact wire.
