Patent ID: 7615930

Claim:
A low-wattage, high intensity arc discharge electric lamp comprising: a thick-walled outer envelope extending along a longitudinal axis and having a bulbous portion and a narrow, cylindrical base including oppositely disposed grooves extending parallel to said longitudinal axis; an electrically conducting mounting member with grippers formed on ends thereof to engage said grooves and having a center portion with a U-shaped segment including two arms positioned within said cylindrical base; an arc tube assembly comprising a ceramic arc tube having axially extending electrode lead-ins sealed within a shroud, said shroud having parallel electrical connections extending therefrom, a first of said electrical connections being electrically and mechanically fixed to said two arms of said U-shaped segment of said electrically conductive mounting member and a second of said electrical connections being electrically insulated from said mounting member by an insulator, said insulator being a glass sleeve; and a threaded shell fixed to said base, said shell having a first electrical contact electrically connected to said electrically conducting mounting member and a second electrical contact electrically connected to said second of said electrical connections.
