Abstract (en)
[origin: WO0215230A1] The invention relates to a compact high-voltage electric light-bulb. As the illuminating body, said bulb comprises a triple coil in the form of a double helix (4), which in turn is configured from a double spiral (4a-4c). The invention allows high-voltage electric light-bulbs with compact dimensions and high light intensities to be produced.
