Title:
高圧放電ランプシステム、およびそれを用いたプロジェクタ
Document Type and Number:
Japanese Patent JP4788719
Kind Code:
B2
Abstract:
A high-pressure discharge lamp system has a high-pressure mercury lamp 4 and a lighting circuit 3 that operates the lamp 4. The lamp 4 includes an envelope having a light emitting part 6 having a first and a second electrode 10, 11 arranged therein and a first and a second sealing part 7, 8 oppositely extending from the light emitting part 6, and a conductor 20 electrically connected to the second electrode 11. Particularly a portion of the conductor 20 is at least in contact with or in closest proximity to the outer surface of the first sealing part 7 substantially at a single point in an area corresponding to a first metal foil 16 connected to the first electrode 10. The circuit 3 activates the lamp 4 by placing high-frequency voltage at a predetermined frequency within a range of 10 [kHz]-10 [MHz], inclusive, between the electrodes 10, 11.
