| Title: |
Plasma Lamp with Small Power Coupling Surface |
| Abstract: |
In an example embodiment, an electrodeless plasma lamp is, provided which
comprises a dielectric body having an effective dielectric constant
greater than two. The dielectric body may have a surface with a first
region coated with an electrically conductive material and a second
region that is not coated with the electrically conductive material. A
bulb is located proximate to the second region of the dielectric body and
having an outer surface area and the second region may have an uncoated
surface area that is less than about sixty percent (60%) of the outer
surface area of the bulb. A power source is coupled to the dielectric
body to provide radio frequency power to the dielectric body at a
frequency that resonates at a fundamental mode in the dielectric body.
The bulb contains a fill that forms a plasma when the radio frequency
power is provided from the dielectric body through the second region.
