Abstract:
A lighting system for generating a pre-determined beam-pattern, said system comprising:a reflector body for reflecting light forwardly thereof said reflector body having an open end; a cover extending across said open end; optical means positioned within said reflector body for generating the pre-determined beam-pattern from said forwardly reflected light; a discharge lamp positioned between the reflector body and said optical means, said discharge lamp comprising: a sealed discharge vessel made of ceramic light-transmitting material and containing an ionizable fill and having means for making the discharge lamp at least approximately a point-like light source, and a pair of spaced-apart electrodes within the discharge vessel between which an electric discharge is developed when the lamp is operated; an operating circuit for igniting the discharge lamp and providing for steady-state operation thereof; and, a lamp base for supporting and positioning the discharge lamp and including contact terminals for connecting the operating circuit to a power supply.
