1. A structure for displaying operation status of a power supply which provides a power source to transform external power to DC driving power and has an air fan and a fan driving circuit connecting to a detection element to detect operation temperature inside the power supply and output a temperature control signal, the fan driving circuit determining the DC driving power to drive the air fan to get a desired rotation speed through the temperature control signal, the structure comprising:

  • a status display circuit in the power supply that includes at least two switches and two lighting elements, the switches being set at different ON/OFF levels and triggered by the temperature control signal or the fan driving circuit to determine whether ON/OFF of the switches be activated, the lighting elements being connected to the switches and driven by the DC driving power to emit light in the ON condition of the switches, the status display circuit driving the lighting elements to display operation status of the power supply when the rotation speed of the air fan alters.
