Light signal for rail-bound traffic routes, has funnel-shaped diaphragm that is arranged between light source and optical system, and whose inner surface is provided with light-absorbing structure for achieving phantom light reduction

摘要

The light signal has light source (1) and optical system (2) that are provided for signal aspect visualization in remote area towards angle closed range. A funnel-shaped diaphragm (3) is arranged between the light source and optical system, and an inner surface of funnel-shaped diaphragm is provided with light-absorbing structure for achieving phantom light reduction which is sufficient to dispense with barge.
