Incandescent bulbs use a filament to generate light. This filament has a lot of electrical resistance, so passing a current through it causes it to heat up and eventually glow.

The aim of this paper is to study the heat dissipation enhancement effect of LED filament bulb by using ionic wind. A LED filament bulb with 6 filaments is used for studying. There are two holes ...

However, a team of researchers from the Massachusetts Institute of Technology (MIT) have devised a way of capturing the infrared heat released when the tungsten filament of an incandescent bulb is ...
