Abstract: Method for introducing a limited amount of mercury into a fluorescent lamp during manufacture thereof includes the steps of forming the lamp with an exhaust tubulation therein open at an end thereof, exhausting the interior of the lamp through the exhaust tubulation, placing a body of metal material not reactive with mercury in the exhaust tabulation open end; the body having a coating of metal which amalgams with mercury, over a selected surface area of the body, and having mercury on the coated area of the body, such that a limited amount of the mercury is retained by the metal coating, and sealing the open end of the exhaust tubulation, whereby the amount of mercury retained on the body and introduced into the lamp is limited by the surface area of the metal coating on the body.

Abstract: An amalgam assembly for a fluorescent lamp includes a glass exhaust tubulation extending toward a base portion of the lamp, the tubulation being closed at an end thereof adjacent the lamp base portion, and a retaining structure disposed in the tubulation and retained by a pinched portion of the tubulation. A mercury amalgam body is disposed in the tubulation between the retaining structure and the tubulation closed end. The amalgam body includes means for wetting internal surfaces of the glass tubulation to cause the amalgam to adhere to the tubulation internal surfaces when the amalgam body is liquidized, and to thereby prevent the amalgam from flowing past the retaining structure and into the lamp envelope.

Abstract: An amalgam assembly for a fluorescent lamp includes a glass exhaust tabulation extending toward a base portion of the lamp, the tabulation being closed at an end adjacent the lamp base portion, and a metal cup disposed in the tubulation and retained by a pinched portion of the tabulation. The cup defines an annular outer wall having a free edge extending toward the tabulation closed end, a tubular central core portion extending toward the tabulation closed end, and an annular trough formed by the core portion and the outer wall. A mercury amalgam ball is disposed between the metal cup and the tabulation closed end, a diameter of the ball exceeding an inner diameter of the core portion, and a coating of a metal wetting agent is disposed on interior surfaces of the trough.

Abstract: A method for making a ceramic body is provided wherein the ceramic components are joined in their green state. The method includes applying heat to the surfaces to be joined to cause a localized melting of the binder. The surfaces are then brought together and joined by alternately applying compression and stretching. The method is particularly advantageous for forming unitary ceramic arc tube bodies for high intensity discharge (HID) lighting applications.

Abstract: A closed-loop tubular lamp envelope and methods of manufacturing closed-loop, tubular lamp envelopes are disclosed. A dome is formed at one end of a light-transmissive tube. A blister is molded on the dome, and a hole isformed in the molded blister. Next, a dome is formed at the other end of the light-transmissive tube. A blister is formed on the dome, and a second hole is formed in the molded blister. Each of the molded blisters includes a rim which defines the respective hole. A second tube is processed in the same way. The respective rims at the ends of the first and second tubes are fused together to form a sealed, closed-loop lamp envelope. Each tube may be bent to provide a desired shape of the lamp envelope. The molding of the rims insures that the sealing surfaces match.
