摘要： An integrated reflector lamp includes a sealed envelope enclosing a high pressure gas discharge device. A shell has a rim portion which receives the sealed envelope and an opposing basal portion carrying a screw base. A ballast for igniting and operating the discharge device is enclosed within the shell between the screw base and the sealed envelope. The sealed envelope includes a reflective surface which directs light emitted by the discharge device. The reflective surface also provides effective heat management for preventing overheating of the ballast by the heat generated by the discharge device. The integrated lamp has photometrics and luminous efficacy which exceeds that of corresponding halogen and halogen IR reflector lamps while having an overall planform which fits within that of the corresponding lamp. In a favorable embodiment, the ballast drives the discharge device at a high frequency above about 19 kHz and below the lowest acoustic resonant frequency of the discharge device, facilitating a small physical size for the ballast while also avoiding acoustic resonance. In one embodiment, the reflector lamp fits within the ANSI outline for a PAR 38 lamp and has total lumens at least substantially equal to and a luminous efficacy which substantially exceeds that of a corresponding PAR 38 lamp having an incandescent filament.

摘要： A discharge vessel with a ceramic wall is filled with inert gas and metal and is ignited and operated by an electronic circuit including a half bridge converter with an LC circuit which, when the lamp is not ignited, enters an oscillation state near a resonance frequency which lies near the third harmonic of the switching frequency of the half bridge converter. The vessel encloses a cylindrical discharge space of diameter D and length L, wherein L.ltoreq.D.ltoreq.1.2 L.

摘要： The invention relates to a high-pressure discharge lamp provided with a discharge vessel which is enclosed with intervening space by an outer bulb with a lamp cap, which lamp also comprises an UV-enhancer having a wall and an internal electrode and arranged in the space between outer bulb and discharge vessel. According to the invention, the wall of the UV-enhancer is made from ceramic material. The invention offers the advantage that the lamp ignites reliably at a comparatively low ignition voltage of 3 kV already.
