The invention relates to the technical field of LED lamp production equipment, in particular to a structure for testing LED lamp power. The structure comprises a testing station, a stopping mechanism,a positioning mechanism, a testing mechanism, a compression mechanism and a moving carrier, wherein the testing station and the conveying belt of a production line are located on the same plane, thestopping mechanism is located on one side of the testing station, the positioning mechanism and the testing mechanism are located below the testing station, the compression mechanism is located abovethe testing station, and the moving carrier is used for loading a to-be-tested LED lamp; the stopping mechanism is used for stopping the moving carrier to allow the same to be located at the testing station; the positioning mechanism jacks up the moving carrier, and the compression mechanism compresses the moving carrier and is used for clamping and fixing the moving carrier; the testing mechanismcontacts with the power contacts of the LED lamp and is used for performing power testing on the LED lamp. By the structure, the technical problem that traditional manual testing is high in labor cost and has potential safety hazards is solved.
