The present invention relates to an apparatus for controlling lighting of a crosswalk, capable of storing the identity and working time of a worker and managing a maintenance history of a device. According to the present invention, an apparatus for controlling lighting of a crosswalk includes a housing, a control unit, a power supply unit, a communication module, a sensing module, a locking device, a remote circuit breaker, and an auxiliary power supply unit. The housing has a cover which is able to be open or closed. The control unit is disposed inside the housing. The power supply unit includes a switch mode power supply (SMPS) to transform power supplied from the outside. The communication module receives a walk signal from a traffic signal controller. The sensing module measures amounts of a voltage, a current, and power of a transmissive lamp which is additionally provided. The locking device includes a confirmation sensor, which senses the opening and closing of the housing, and has a dual mechanical and electronic structure. The remote circuit breaker breaks electricity when power, which exceeds an allowable voltage range, is introduced or electricity short is caused. The remote circuit breaker is accessible through the communication module by a worker outdoors, such that the worker is able to operate the remote circuit breaker. The auxiliary power supply unit supplies a current such that the control unit may store data when power supply is stopped.
