Abstract
A solid halogen-containing lamp fill material and a method of introducing small amounts of halogen into a HID lamp are disclosed. The solid material may include an admixture of a metal and a metal halide in the form of spheres of high purity, uniform size and uniform composition. Solid lamp fill material and methods of introducing small quantities of one or more metals into a HID lamp are also disclosed.
Claims56
A solid fill material for the arc tube of a HID lamp comprising a metal halide dispersed within.
A solid lamp fill particle formed by dissolving a metal halide in a molten metal without forming two immiscible liquids and without forming separate molten metal and solid or liquid metal halide phases.
A particle comprising of metal and a halide of said metal.
A particle comprising:
- (a) a metal from the group consisting of Bi, Cd, In, Sn, Tl and Pb;
- and
- (b) a metal halide from the group consisting of BiX3, InX3, SnX2, TIX and PbX2, where X is from the group consisting of Cl, Br or I.
A solid fill material for the arc tube of a HID lamp formed by dissolving a halide of one or more metals in one or more molten metals.
A particle suitable for introduction into the arc tube of a HID lamp, said particle being formed by admixing one or more metals with a halide of one or more metals, melting the admixture, and cooling the admixture to form lamp particles.
A particle comprising one or more metal halides dissolved in one or more metals.
A solid lamp fill material forming a particle comprising one or more metal halides and one or more metals wherein the composition of the material is homogeneous.
A solid lamp fill material comprising one or more metal halides and one or more metals wherein the composition of the material is homogeneous, and wherein the metal in the one or more metal halides is the same as the one or more metals.
