Further, after the above-mentioned modulation signal is obtained, the LED light source 200 of the tunnel lamp may be regularly driven in a PWM manner to emit a light signal according to the modulation signal by the driving power supply 100 of the tunnel lamp. The light signal emitted by the LED light source 200 of the tunnel lamp corresponds to the modulated signal. When other devices pass through the tunnel lamp, the visible light communication components of the other devices can receive the light signals sent by the LED light source 200, and the position information of the tunnel lamp is analyzed according to the received light signals.
