Abstract
A plasma lamp apparatus. The apparatus can have a bulb coupled to at least the first end of a support member that is provided within a housing having an interior and exterior region. The housing can also have a first coupling member disposed within the housing, and a gap can be provided between the first coupling member and the support member. Additionally an rf source can be coupled to the support member. A fill material, which can include at least a first volume of a rare gas, a first amount of a first metal halide, a second amount of a second metal halide, and a third amount of mercury, can be spatially disposed within the bulb.
Claims31
A plasma lamp apparatus comprising:
- a housing having an interior region and an exterior region, the interior region configured with a hollow spatial volume forming an air resonator;
- a support member provided within an interior region of the housing, the support member having at least a conductive exterior region, the support member having a first end and a second end;
- an RF source coupled to the support member;
- a bulb coupled to at least the first end of the support member, the bulb having an internal volume ranging from about 0.2 cubic centimeters to about 0.5 cubic centimeters;
- a first coupling member disposed within the spatial volume of the housing;
- a gap provided between the first coupling member and the support member;
- and
- a fill material comprising argon gas, thulium bromide, indium bromide, and mercury, the fill material being disposed within the bulb.
A plasma lamp apparatus comprising:
- a housing having an interior region and an exterior region, the interior region configured with a hollow spatial volume forming an air resonator;
- a support member provided within an interior region of the housing, the support member having at least a conductive exterior region, the support member having a first end and a second end;
- an RF source coupled to the support member;
- a bulb coupled to at least the first end of the support member, the bulb being configured to extend outside the housing such that an arc of the bulb is not surrounded by walls of the resonator, the bulb having an internal volume ranging from about 0.2 cubic centimeters to about 0.5 cubic centimeters;
- first coupling member disposed within the spatial volume of the housing;
- a gap provided between the first coupling member and the support member;
- and
- a fill material spatially disposed within the bulb, the fill material having at least a first volume of a rare gas, a first amount of a first metal halide, a second amount of a second metal halide, and a third amount of mercury.
