Abstract
An induction lamp includes a brightness control module, an induction unit, a register, and an illuminating unit. The brightness control module, the induction unit, the register, and the illuminating unit are electrically connected to each other in that order. When the induction unit detects a control signal from a user, the induction unit sends a detecting signal to change an address of the register, and the brightness control module controls a brightness of the illuminating unit depending on the address of the register.
