Abstract:
In a method of fabricating a planar light source, a first substrate is formed at first. First electrodes approximately parallel to each other are formed on the first substrate. Sets of first dielectric patterns are formed on the first substrate. Each set of the first dielectric patterns includes at least two first striped dielectric patterns, and each of the first striped dielectric patterns covers one of the first electrodes correspondingly. The edges of the top of each first striped dielectric pattern are raised in a peak shape. A phosphor layer is formed between the first striped dielectric patterns of each set of the first dielectric patterns. A second substrate is formed. The first and second substrates are bound; meanwhile, a discharge gas is injected into the discharge space.

A low-pressure discharge lamp having a tubular glass lamp vessel 10, on an outer surface of which conductor layers are formed as electrodes 21 and 26. The ultrasonic solder dipping layers 31 and 36 are formed at both ends of the vessel 10 as conductor layers. The end surfaces of the glass lamp vessel are blasted and ultrasonic solder dipping layers are formed on the blasted surfaces 41 and 46 by ultrasonic solder dipping. Conductor layers form external electrodes 21 and 26, which are in contact with the glass surface more strongly. A low-pressure discharge lamp having the conductor layers of a uniform thickness can be mass-produced at low cost.

The first and second electrodes are disposed at two ends of the discharge tube in a direction of a longitudinal axis thereof, respectively. A length of a first wiring for coupling the power source to the first electrode is approximately equal to a length of a second wiring for coupling the power source to the second electrode.
Abstract:
A method for fabricating microcavity discharge devices and arrays of devices. The devices are fabricated by layering a dielectric on a first conducting layer. A second conducting layer or structure is overlaid on the dielectric layer. In some devices, a microcavity is created that penetrates the second conducting layer or structure and the dielectric layer. In other devices, the microcavity penetrates to the first conducting layer. The second conducting layer or structure together with the inside face of the microcavity is overlaid with a second dielectric layer. The microcavities are then filled with a discharge gas. When a time-varying potential of the appropriate magnitude is applied between the conductors, a microplasma discharge is generated in the microcavity. These devices can exhibit extended lifetimes since the conductors are encapsulated, shielding the conductors from degradation due to exposure to the plasma. Some of the devices are flexible and the dielectric can be chosen to act as a mirror.
