Abstract
An ultrasonic lamp control method is provided. The control method includes the following steps. The ultrasonic lamp emits a first burst, and detects whether a first echo is received within a fixed period of time after the emission of the first burst. If the first echo is received within the fixed period of time, then the ultrasonic lamp neglects the first echo and emits a second burst. The ultrasonic lamp detects whether a second echo is received within the fixed period of time after the emission of the second burst. If the second echo is received within the fixed period of time, then the ultrasonic lamp enters a control mode.
