ABSTRACT:
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.
