Both the signal sending module 31 and the signal receiving module 11 are power carrier communication modules. The power carrier communication module uses the transmission line as the transmission medium of the carrier signal. Since the transmission line has a very strong support structure, the transmission line is used to transmit the carrier signal while transmitting the current, which is economical and very reliable, and the external wiring is simple and easy. maintain.

The intelligent communication energy-saving LED tunnel light has a built-in single-chip microcomputer to realize the control of the control switch 2 . When a vehicle passes by, the signal sending module 31 outputs a signal, and the signal is transmitted to the signal receiving module 11 through the transmission line 7, and the multi-channel constant current driver 1 closes the control switch 2, and the auxiliary The LED light of circuit 5 lights up to play the role of sufficient illumination. When there is no car passing by in the tunnel, only about 25% of the illuminance is retained, maintaining the basic ambient lighting can greatly save energy by up to 75%.
