In addition, various monitors such as an inspection monitor, a charging monitor, and a lamp monitor may be added to the retrofitted multifunction module 6. These monitors are arranged at the bottom of the multifunction module 6 so that the inspector can observe the monitor through the through hole 72. Further, a monitor for detecting whether or not the multifunction module 6 is correctly connected may be added to the multifunction module 6 as a monitor.

Further, the antenna of the multifunction module 6 may be formed into a string shape, and the tip of the string-shaped antenna may be projected from the through hole 72 to further increase the sensitivity of transmitting and receiving radio waves of the multifunction module 6. Further, the string-shaped antenna may also serve as an activation switch for the inspection operation of the lighting device 10, and the lighting device 10 may start the inspection operation by pulling the string-shaped antenna. The shape of the antenna of the multifunction module 6 is not limited to the shape of a string. That is, when the antenna of the multifunction module 6 is pulled, the inspection operation of the lighting device 10 is activated, and the tip of the antenna or a predetermined range of the antenna moves from the through hole 72 to the outside of the housing 2 of the lighting device 10. Any shape of the antenna can be adopted as long as the propagation strength of the radio wave used for wireless communication can be improved by exposing the antenna.

Further, in the present embodiment, an example is an illuminating device 10 having a structure in which each component is arranged inside a bottomed cylindrical housing 2 having an opening on one side and then the opening 21 is closed with a substantially disk-shaped lid 7.
