• a lamp information collection circuit;
• a controller;
• and
• a user terminal;
• wherein the controller has a built-in power information interval comparison table setting different intervals for different lamp categories, and sends to-be-collected power information to the lamp information collection circuit;
• the lamp information collection circuit is used to collect corresponding power information according to the received to-be-collected power information and send the collected power information to the controller;
• the controller is further used to determine a category of a lamp according to the collected power information corresponding to the lamp and the power information interval comparison table, and send information of the lamp to the user terminal;
• and
• the user terminal comprises a human-machine interface and is used to display the information of the lamp on the human-machine interface;
• wherein, a power information interval comprises one of a voltage interval, a current interval, or a frequency interval, and ranges of the power information interval do not overlap with each other.
