Abstract
A light emitting diode (LED) lamp electrically connected to a switch is provided. The LED lamp includes a lamp body, an LED array disposed inside the lamp body, and a current control circuit disposed inside the lamp body. The current control circuit is electrically connected between the LED array and the switch. The current control circuit is capable of outputting various driving currents to the LED array according to the number of flashing times of the switch, so as to modulate the intensity of light emitted from the LED array. Since the above-mentioned LED lamp has the built-in current control circuit, users are capable of modulating the intensity of light emitted from the above-mentioned LED lamp by flashing the switch.
Claims18
An illumination system, comprising:
- a switch;
- an LED light source;
- and
- a current control circuit electrically connected between the switch and the LED light source, wherein when the switch is turned ON, the current control circuit outputs a driving current to change a brightness of the LED light source from a first brightness to a second brightness, and wherein the switch is intermittently actuated-deactuated to stop the change of the brightness, thereby maintaining the brightness of the LED light source at a third brightness.
