The present invention discloses an light emitting diode (LED) light source and an interface for providing power to the LED. The LED light source includes an LED unit and a second coupling unit. The LED unit includes a base, one or more LED, and a first coupling unit. The LED are attached to the base. The joining of the first and second coupling units provides a mechanical support and electricity to the LED. The LED, are connected with independent circuit loops and controlled by controller to change the brightness of the LED. This structure allows the second coupling unit to be applied to any luminaries or replacement of a traditional light source, thus making the LED unit a universal LED light source for mass production and cost reduction. With the use of various types of LED and electric current control, modulation of brightness, color, and color temperature may be achieved.
