摘要： A high pressure gas discharge lamp system includes a high pressure discharge lamp selected to have a lowest lamp resonant frequency above the audible, on a current basis above about 19 kHz and on a power basis of above about 38 kHz. The ballast circuit energizes the discharge device so as to have a fundamental frequency below the lowest lamp resonant frequency and above the audible, while keeping the magnitude of any harmonics above the lowest lamp resonant frequency sufficiently small so as to avoid acoustic resonance. By operating below the lowest lamp resonant frequency, greatly simplifying ballast construction and cost. According to one embodiment, the discharge vessel encloses a discharge space which is circular cylindrical and having a L:ID ratio of about 1:1 to maximize the lowest lamp resonant frequency. According to another embodiment, two or more discharge devices are operated concurrently by the ballast, each having a lowest lamp resonant frequency of above the audible, and the ballast operating frequency so as to increase light output while still avoiding acoustic resonance.

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 ceramic gas tight high-pressure burner includes an ionizable filling. The burner further includes a discharge vessel having a discharge cavity with a volume in the range of 3 mm3 to 30 mm 3, and an internal filling pressure of the discharge cavity in the range from 0.1 MPa to 4 MPa at room temperature. An end closure of the burner may be designed as a three-part, a two-part or a one-part end closure device with a reduced crevice.
