Zero energy storage driver integrated in led chip carrier

Abstract

LED devices are provided that include LED chips on LED chip carriers. The LED device can in turn be housed in a package, such as a small-outline transistor (SOT) package or a radial LED device package. A single LED device or a serial connection of a plurality of such LED devices can be operated directly from an AC (line) voltage or a rectified version thereof. In some example embodiments, switching circuitry is integrated into the LED chip carrier for controlling current flow through the LED(s) in response to, for example, a brightness regulating control signal. Numerous example embodiments of the monolithic LED devices are provided, including manufacturing processes as well as various example packages for such LED devices.
