Abstract
An external electrical-control lamp with improved structure includes a light-emitting diode lamp (), an external power box (), and a dimmer (). The light-emitting diode lamp () has a circuit board (), at least one light-emitting diode (), a thermal module (), and a rectifying circuit (). The light-emitting diode () is installed on the circuit board (), the thermal module () provides a heat-dissipating function to the light-emitting diode (), and the rectifying circuit () provides a rectified power to the light-emitting diode (). When a utility power () is supplied to the dimmer () and the external power box (), a variable resistor of the dimmer () is adjusted and the utility power () is controlled by the external power box (), thus adjusting the brightness of the light-emitting diode ().
