Abstract: An RF electrodeless plasma lamp with improved efficiency in higher lumens per watt includes a waveguide body, in which an RF signal drives the entire structure at the resonant frequency of the structure. The resonant frequency of the structure is lowered by increasing the overall capacitance of the waveguide body by adding at least two layers of dielectric material between the input feed and the bulb of the lamp. The layered structure can include an air cavity disposed between a dielectric layer and the input feed. In lowering the resonant frequency of the lamp, the device is capable of using RF amplifiers that have higher efficiency, and thus has a higher lumens per watt ratio.

Abstract: A plasma lamp apparatus that includes an improved bulb support assembly to increase the lumens per watt output of the apparatus. The bulb support assembly includes a support structure that forms a cavity for receiving the bulb. The bulb is supported within the cavity though a protrusion that extends out from the support structure in a curved manner. By created a curved protrusion, the electric field within the resonating structure of the lamp apparatus is lowered. Lowering the electric field leads to lower resonating frequencies of the resonating structure. In lowering the resonating frequency, the resonating structure is driven to resonate at lower power levels, thereby increasing the lumens per watt output of the lamp apparatus.

Abstract: A dielectric waveguide integrated plasma lamp (DWIPL) with a body comprising at least one dielectric material having a dielectric constant greater than approximately 2, and having a shape and dimensions such that the body resonates in at least one resonant mode when microwave energy of an appropriate frequency is coupled into the body. A dielectric bulb within a lamp chamber in the body contains a fill which when receiving energy from the resonating body forms a light-emitting plasma. The bulb is transparent to visible light and infrared radiation emitted by the plasma. Radiative energy lost from the plasma is recycled by reflecting the radiation from thin-film, multi-layer coatings on bulb exterior surfaces and/or lamp chamber surfaces back into the bulb. The lamp further includes two- or three-microwave probe configurations minimizing power reflected from the body back to the microwave source when the source operates: (a) at a frequency such that the body resonates in a single mode; or (b) at one frequency such that the body resonates in a relatively higher mode before a plasma is formed, and at another frequency such that the body resonates in a relatively lower order mode after the plasma reaches steady state.
