Abstract
A lamp assembly includes a reflector body having an integral crimping portion that extends inwardly over a channel formed in the reflector body, a seal feature arranged within the channel, a cathode assembly having an edge feature extending into the channel, and a resilient member held in a state of compression between the crimping portion and a first surface of the edge feature such that an opposing second surface of the edge member is held against the sealing feature thereby creating a hermetic seal between the cathode assembly and the reflector body wherein the crimping portion is configured to remain in contact with the resilient member if the hermetic seal becomes non-hermetic.
Claims24
A lamp assembly, comprising:
- a reflector body having an integral crimping portion that extends inwardly over a channel formed in said reflector body;
- a seal feature arranged within said channel;
- a cathode assembly having an edge feature extending into said channel;
- and
- a resilient member held in a state of compression between said crimping portion and a first surface of said edge feature such that an opposing second surface of said edge member is held against said sealing feature thereby creating a hermetic seal between said cathode assembly and said reflector body wherein said crimping portion is configured to remain in contact with said resilient member if said hermetic seal becomes non-hermetic.
A lamp assembly, comprising:
- a integral reflector and heat sink, said integral reflector and heat sink including a plurality of cooling fins formed on a first end and a cavity defined in a second end, said cavity being surrounded by an opening and having crimping portions extending beyond said opening;
- a ring seal disposed about said opening;
- an isolation ring coupled to said opening;
- and
- a spring washer coupled to said isolation ring, wherein said crimping portions are configured to be selectively deformed to exert a compressive force on said spring washer, said isolation ring, and said ring seal to provide a hermetic seal between said ring seal and said isolation ring below a first pressure threshold and to provide a gas escape pathway above said first pressure threshold.
A display system, comprising:
- a lamp assembly including an integral reflector and heat sink having crimping portions, a cathode assembly having an isolation ring coupled thereto, a spring washer located at least partially between said crimping portions and said isolation ring;
- and a generally ring shaped seal located between said integral reflector and heat sink and said isolation ring for providing a hermetic seal between said integral reflector and heat sink and said cathode assembly wherein said crimping portions are configured to remain in contact with said spring washer if said hermetic seal becomes non-hermetic;
- an illumination optics assembly optically coupled to said lamp assembly;
- and
- a spatial light modulator optically coupled to said illumination optics assembly.
A method of sealing a lamp assembly, comprising:
- coupling a ring seal to an integral reflector and heat sink, said integral reflector and heat sink having at least one crimping portion;
- coupling a cathode assembly to said ring seal;
- coupling a spring washer to said cathode assembly;
- and
- selectively crimping said crimping portions against said spring washer to apply a compressive force to said spring washer, said compressive force resulting in a sealing force between said ring seal and said cathode assembly below a first pressure threshold and providing a gas escape pathway above said first pressure threshold.
A lamp assembly, comprising:
- light generating means for producing concentrated light in the presence of pressurized gas;
- a window;
- sealing means coupled to said window for sealing said pressurized gas within said lamp assembly
- reflector means for reflecting said concentrated light to a desired location, said reflector including retaining means for retaining said sealing means and said window in contact therewith while providing a gas escape pathway for said pressurized gas when said pressurized gas exceeds a first pressure threshold.
