This is a schematic diagram of a new type of filter that could revive incandescent lighting and make possible more efficient solar electricity generation. The schematic shows the technology from a ...

Traditional, incandescent light bulbs have long been on their way out. First made commercially available by Thomas Edison, the technology has remained largely unchanged for more than a century now: it ...

This month, let’s take a deeper look at one of the most ubiquitous forms of illumination in our world: tungsten or incandescent bulbs. Incandescent means light from heat, which also includes the light ...

Traditional light bulbs, thought to be well on their way to oblivion, may receive a reprieve thanks to a technological breakthrough. Traditional light bulbs, thought to be well on their way to ...

The automotive lighting industry has undergone a massive transformation with the growing trend toward LED-based light sources. As recently as 1990, the standard headlight assembly used only ...

When LEDs were first introduced, it was hard for us to part with our old friends incandescent and halogen lamps, and the luminaires made for them. It seemed like nothing could ever replace the warm ...

Solid-state lighting (SSL) differs from conventional lighting in that it uses light-emitting diodes (LEDs) instead of filaments, plasma, or gases. Although still relatively early in its development, ...

Incandescent light bulbs, considered wasteful of heat, could potentially be improved in efficiency, according to researchers working at MIT in Cambridge, Massachusetts. Using tech not radically ...

Solid-state lighting (SSL) is creating a revolution in lighting. Two light sources that constitute SSL (inorganic light-emitting diodes or LEDs and sister technology organic light-emitting diodes, ...

http://www.dialight.comInitially, the interest in replacing incandescent lamps with light-emitting diodes (LEDs) was sparked by the potential to reduce energy ...

Engineers have created what may be viewed as the world's smallest incandescent lightbulbs, collections of near-nanoscale materials called 'selective thermal emitters' that absorb heat and emit light.

Sources of incandescence emit their radiation across a broad spectrum. The finding that metamaterials can be used to tune the sources' emission spectrum makes these emitters an attractive prospect for ...
