Abstract
PURPOSE: To in improve reflection efficiency of a square-shaped sealed beam lamp, by arranging three ferrules to be bored in a paraboloid reflector so that the three ferrules may be displaced in a clockwise direction around a center axis of the reflector to a degree not to cause two common leads to cross each other.
