<P>PROBLEM TO BE SOLVED: To provide an LED package including an integrated circuit for matching a power source voltage to the LED operating voltage. <P>SOLUTION: An integrated circuit typically includes a power converter 40 and a constant current circuit 44. An LED package may also include other active or passive components such as pin-outs for integrated or external components, a transformer and a rectifier, or a rectifier circuit. The external components can include control systems for regulating the current level of an LED 46 or the properties of light emitted by the LED. Integrating the power supply and current control components into the LED can provide for fabrication of relatively small LEDs using fewer and less device-specific components. <P>COPYRIGHT: (C)2013,JPO&INPIT |
