Abstract
A light source system includes a heat sink. A base connector receives electrical power. A housing is secured to the base connector. A ballast unit is secured within the housing and electrically connected to the base connector. At least one electrical component is both mechanically and electrically connected to the ballast unit. The at least one electrical component is driven by the electrical power received by the base connector. A lamp unit is secured to the housing and electrically connected to the ballast unit. An additional electrical component includes a portion which contacts an inside wall of the housing. The additional electrical component is electrically connected to the ballast unit and has a life span which decreases as an operating temperature of the additional electrical component increases. The inside wall of the housing acts as the heat sink for the additional electrical component. The operating temperature of the additional electrical component is reduced by dissipating heat from the additional electrical component via the portion contacting the inside wall of the housing.
