In 1923 at Tungsram Limited., a research laboratory was established for improving light sources, mainly electric bulbs. The head of that laboratory was Ignácz Pfeiffer (1867-1941), whose research staff included Szigeti, along with Zoltan Bay (1900-1992), Tivadar Millner, Imre Bródy (1891-1944), Ernő Winter (1897-1971), and others Szigeti worked together with Zoltan Bay on metal-vapor lamps and fluorescent light sources.
They received a United States. patent on "electroluminescent light sources" that were made of silicon carbide.
These light sources were the ancestors of light-emitting diodes (LEDs).
