ABSTRACT:
A lamp power transformer circuit which is packaged in a module housing having the same size, shape and cross section as a linear lighting fixture to which it is attached. The transformer circuit is designed to rectify input 60 Hz power and to switch the DC at a high frequency through a small stepdown magnetic transformer, to produce a lamp supply voltage of 12 volts, 30 KHz. The invention produces a light weigth lamp transformer, having a high operating efficiency, and sized for attaching to a previous invention, linear lighting fixture which incorporates low voltage halogen lamps.
