A display system for a traffic signal and a traffic signal

摘要

A Traffic Safety (TS) panel 20 can be easily observed with a traffic signal 10. Multiple pieces of information are changed over to be displayed on the TS panel 20, and a luminescent color of the information (such as traffic information, traffic slogans, advertisements) or a luminescent color of the background of the information is illuminated in the same color as that of the turned-on light of the traffic signal 10, under control of a detector which detects whether each lamp of the traffic signal is turned on or not without changing an electric circuit of the signal. As a result, various information can be displayed on the TS panel 20, and a signal color can be recognized not only by a signal lamp but also by a display color of the TS panel 20. A traffic signal can consist of a luminescent panel displaying changeable symbols with a changeably-coloured background.
