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.
Scope Notes
Glossary: Lamp lamps "Lamp" includes tubes emitting ultra-violet or infra-red light. | Limiting references: Details or apparatus or processes for manufacture applicable to both discharge devices and incandescent lamps Lamps with light-emitting discharge path and separately-heated incandescent body within a common envelope, e.g. for simulating daylight Lamps with spaced electrodes heated to incandescence by light-emitting discharge, e.g. tungsten arc lamps Electric light sources using a combination of incandescent and other types of light generation | Application references: Functional features or details of lighting devices or systems thereof Structural combinations of lighting devices with other articles, not otherwise provided for Incandescent filaments used to form characters in indicating arrangements
