Abstract

An LED-based lamp assembly with a driver assembly having a base portion rotateably engageable with the socket of a light fixture to make a first electrical contact with the light fixture. The driver assembly makes electrical contact with the light fixture. A lamp housing assembly operably connected to the driver assembly has a lamp housing connected to the driver assembly. The lamp housing is coupled to an integrated circuitry arrangement with at least one LED light thereon. The integrated circuitry arrangement is connected to, or is an integral part of, a heat sink that carries heat away from the substrate and/or LED light. The heat sink and the integrated circuitry arrangement have apertures hat allows heated air from the heat sink to pass therethrough and away from the LED light.
