The invention discloses a traffic signal system, a traffic signal lamp and a state detection method thereof. The traffic signal lamp comprises a plurality of light-emitting devices. Each light-emitting device comprises a light-emitting part, a power distribution module, a power module, a controller and a measuring device. The power supply module is used for converting alternating current into direct current and supplying the direct current to the light-emitting part and the power supply distribution module. The measuring device is electrically coupled to the power distribution module and the light-emitting member. The controller is electrically coupled to the power distribution module and the measuring device. When the selected person of the light-emitting devices receives the alternating current, the power distribution module of the selected person provides the direct current to the controller and the measuring device of the selected person and the power distribution modules of the rest of the light-emitting devices.
