Abstract:
A lamp including a heat sink system, the lamp comprising:a housing;a base connector, for receiving electrical power, mounted in a wall of the housing;a ballast unit secured within the housing and electrically connected to the base connector;a lamp unit secured to the housing and electrically connected to the ballast unit;at least one electrical component both mechanically and electrically connected to the ballast unit, the at least one electrical component being driven by the electrical power received by the base connector; andan independent electrical component, having a life span which decreases as an operating temperature of the independent electrical component increases, electrically connected to the ballast unit, the independent electrical component being positioned to directly contact the wall of the housing to create a thermally conductive path between the independent electrical component and the wall of the housing whereby the housing is a heat sink for the independent electrical component.
