Abstract: An integrated high brightness electrodeless lamp includes a lamp base defining two or more compartments housing components of the lamp, wherein at least one compartment provides an opening in the lamp base, a cover fitted to the lamp base, and an optics assembly positioned in the opening in the lamp base, wherein the lamp base, the cover, and the optics assembly provide an RF sealed system. The lamp components include an RF source providing RF energy for the lamp, an aperture bulb assembly including an electrodeless envelope containing a discharge forming fill which emits light when excited by RF energy, and an excitation structure for coupling RF energy from the RF source to the discharge forming fill. The optics assembly may be mounted in the opening in the lamp base with a twist lock mounting structure.
