H01K ELECTRIC INCANDESCENT LAMPS (details, apparatus or processes for manufacture applicable to both discharge devices and incandescent lamps H01J; light sources using a combination of incandescent and other types of light generation H01J61/96, H05B35/00)
Introduced: September 1968
Description
H01K covers the design, construction, and technical aspects of electric incandescent lamps, including filament materials, lamp envelopes, base designs, and internal structures. This classification encompasses traditional tungsten filament bulbs, halogen incandescent lamps, and various lamp configurations for general lighting and specialized applications. Related thermal radiation generation methods and specific lamp control systems are generally found in adjacent classes, while discharge lamps and solid-state lighting devices are classified separately.
