Solid Cathode Details TRIZ Cases

Pulsed argon or xenon plasma in a hermetic thermionic converter cuts arc drop and cesium ion flux, enabling more efficient lower-temperature operation.

Pulsed startup voltage alternates anode-cathode potential to suppress intense plasma, cut heat loss, and start ion pumps at higher pressure.

Introducing a low ionization energy metal mediator prevents zinc ion penetration and devitrification, maintaining high ultraviolet output.

Discharge sustaining fill with cesium and rare earth halides produces bright white light at high arc wall loadings.

A vacuum ultraviolet photon source uses external dielectric barrier discharge to generate excimers and transmit photons through a window.

Vanadium and zirconium fill stabilize vapor pressure, reducing color temperature fluctuations during dimming.

Segmented electrodes merge parallel sources to ensure uniform plasma distribution, eliminating the need for expensive large heat-resistant insulators.

Fabricating a one-piece tungsten base via EDM eliminates plate interfaces to prevent leakage while enabling material recovery.

Iris slots shape the field to maintain plasma symmetry despite waveguide length variations.

Concave portion design with fiber laser welding prevents deformation and hole formation in lamp tube joints.

A single tubular excimer lamp uses a vacuum space between an outer tube and discharge chamber to prevent creeping discharge.

A lamp seal uses a phosphorus-containing composition to protect electrical current conducting arrangements from environmental exposure.

A solid oxide glow discharge cell converts waste materials into hydrogen using a hollow electrode and granular insulator.

Segmented electrical contact with depending leg and seat engager supports light source capsule, eliminating manual cementing.

Optimizing the electrode distance to xenon gas pressure ratio suppresses arc deflection and prevents flicker under mechanical vibration.

Tungsten oxyhalides mediate cycle assistance in quartz vessels, enabling rare earth metal use at lower wall loadings.

A gas discharge tube uses a cylindrical part with a through hole and an insulated shielding part to form a high-density electron region for reliable starting discharge.

A hollow cathode discharge apparatus segments the cathode into multiple independent chambers connected by flow channels to stabilize gas pressure and distribute power uniformly.

Segmented airflow channels cool power modules and backlights, resolving the trade-off between high brightness and increased system complexity.

A high pressure gas discharge lamp uses a specific metal halide composition to achieve high luminous efficiency at low electrical power.

Sliding a permeable mass over the anode casing diverts magnetic flux to trim field strength, resolving magnetizing difficulties with high-energy materials.

Local gas injection lowers plasma density to reduce radiation absorption and boost EUV conversion efficiency from 2.0% to 2.3%.
