The lamp body structure is installed on an apparatus machine erectly and has a body and a light guiding mask. The body is provided with a time displaying module and a plurality of light emitting modules. The time displaying module is installed along an elongated direction of the body. The light guiding mask is transparent and masks the body. The controller is coupled to the body and the apparatus machine for receiving an operating state signal and a machining time signal of the apparatus machine and controlling the light emitting module to emit light and the time displaying module to display the machining countdown based on the operating state signal and the machining time signal, allowing operators to control the operating state and machining time of the apparatus machine effectively.
