Abstract

The invention discloses a train lighting lamp with wireless coverage and wired bridging functions. The train lighting lamp comprises a control unit and at least one light-emitting unit. Each light-emitting unit comprises an LED unit and a packaging body. The control unit comprises a control subunit and at least one temperature detection subunit. The temperature detection subunits are used for detecting internal temperature of the lighting lamp. The control unit transmits a control signal to the control subunit according to internal temperature. The control unit also comprises a wireless coverage unit and a wired bridging module. Wireless coverage and wired bridging of the train lighting lamp can be realized, and the train lighting lamp is energy-saving, high-efficiency and high in utilization rate.

Description
