Latest Patents
One of his latest patents is for an arc discharge lamp with a bimetal strip for fast passive lamp failure. This fluorescent tube type discharge lamp features an end sealed in the base with terminal pins connected to lead wires. The design includes an electrode in the form of a coil with an emitter. The bimetal strip is welded to one of the leads, and when the electrode fails, the strip heats up and contacts a thin-walled portion of the stem, allowing air to enter for passive failure of the lamp. Another notable patent involves emission materials for discharge lamps and a method for manufacturing them. This invention introduces new electrode structures for fluorescent lamps, utilizing a tungsten base structure combined with various electron emissive materials. The composite electrode structure can be formed by coating a tungsten coil with a slurry of these materials or sintering powdered mixtures into a high-density composite.
