Most of such conventional lighting lamps and ventilation fans are connected to a lighting switch and a ventilation switch, respectively, so that their operation is controlled according to a user's operation. However, since the conventional illumination lamp and the ventilation fan have to be operated manually, there has been an inconvenience that the user has to manually operate the ventilation fan to properly adjust the humidity inside the toilet and remove the smell.

Korean Patent No. 10-1121444 ("Lighting interlocking ventilation system and its control method") has been proposed to solve the problems of the conventional illumination lamp and ventilation fan. According to the patent, the sensor unit senses the presence or absence of a user by a sensor unit in a specific space such as a toilet, and automatically controls lighting and ventilation in a specific space to automatically control the ventilation fan, Ventilation system.

However, such a conventional ventilation system also has a disadvantage that the converter is installed separately in the ventilation fan and the lighting lamp, and thus the cost of installing the converter increases and the structure becomes complicated.
