Designers of early indoor LED light bulbs faced numerous technical hurdles, including AC-to-DC conversion, thermal heat-sinking, constraints imposed by current bulb sizes, electrical transients, and ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

LED lightbulbs are more energy-efficient than standard bulbs, but that doesn't mean they work perfectly all of the time. Here's how to troubleshoot these bulbs.

Early carbon light bulbs may have produced graphene, since applying voltage to carbon filaments mirrors what is now called flash Joule heating. Graphene is a transparent, remarkably strong substance, ...
