ABSTRACT:
The convoluted fluorescent lamp component of a compact lamp unit is mechanically and electrically coupled to a base module by a plate-like mounting member which is secured to the module in suspended fashion and has socket means which permit the lamp component and associated energizing-circuit components to be plugged into and removed from the module. The mounting member is structured and oriented to also provide a peripheral air passageway which, in conjunction with vent openings in the module and in a protective cover which is secured to the module, allows air to flow freely through the operating unit and convection-cool the fluorescent lamp. The lamp unit can accordingly be operated at high power loadings without overheating and can also be easily relamped and provided with new circuit components (such as a ballast and/or a starter) to prolong its useful life.
