Abstract: Disclosed are an facilitating debugging electronic device, system and method, reasonably integrates the power-supply interface and the signal interface of the electronic device, matches the conventional output end of the electronic device with the master device, realizes the debugging of electronic devices including semi-finished products of PACKAGE (SMD)/PCBA/COB modules and electronic products, partly overcomes the technical problem of the increase of product volume and cost, which caused by setting different interfaces on electronic devices for various testing, burning and correcting purposes.

Abstract: A ring-shaped LED lamp, including at least three LED chips and at least three pins partially located within a package body. The LED chips are connected in series and have two terminal ends connected to form a closed loop, and the pins are led out from connections between the LED chips. A lamp string includes at least one group of lamps and electrically conductive wires connected to multiple lamps, and each group of lamps includes a plurality of the above-described ring-shaped lamps. Also provided is a control circuit applicable for the lamp string. The control circuit includes an input device, a microprocessor, an output circuit, and a lamp string interface connected to the output circuit. The microprocessor receives a signal from the input device, and sends an I/O signal or PWM signal to the output circuit to trigger a voltage level change of the lamp string interface.
