PROBLEM TO BE SOLVED: To provide an incandescent lamp maintaining a high visible light conversion efficiency even when lighting.SOLUTION: An incandescent lamp includes a filament having: a substrate made of a metal material having a melting point of 2,500K or above; a visible light reflectance ...
An electric current passes through the filament, heating it to a temperature that produces light. Incandescent light bulbs usually contain a stem or glass mount attached to the bulb's base which allows the electrical contacts to run through the envelope without gas/air leaks. Small wires embedded...

An improved incandescent light bulb is described utilizing a textured surface filament design to improve efficacy, longevity and color temperature. Embodiments include a low voltage halogen bulb which may be mounted in a fixture containing power condition and altering circuitry. The fixture may be made...

An object that glowed at a high temperature (such as a piece of coal) was deemed incandescent. By the mid-1800s, the incandescent lamp—aka the lightbulb—had been invented; it contains a filament which gives off light when heated by an electric current. Figurative uses of incandescent soon...
Incandescent lighting, in which a filament is heated to a white-hot temperature and the resulting light is used, converts only about 5% of the electric energy into radiant energy. Ordinary fluorescent lighting is four times as efficient, converting about 20% of the electric energy into radiant ...

With time, the temperature difference (ΔT) between the hot spot and the rest of the filament, at temperature T, increases. Preferential evaporation of W not only darkens the inner surface of the bulb, but thins the filament, making the hot spot hotter, resulting in yet greater evaporation...
