LED filament bulbs, more background

Julie Allen at EdisonReport.eu has a piece with a bit more background on “filament” style LED bulbs.  The key IP for the filament-style construction is held by EPISTAR: LED Filaments are usually constructed by applying light emitting diodes on a transparent substrate, allowing light to be emitted from all sides. This omnidirectional light emission results in a higher energy efficiency level, as the light does not get “trapped” in the LED package itself. This increased efficiency of the LED filaments allows for more attractive light bulb shapes, without obstructive large heat sinks that limit application use. The traditional looking format … Continue reading LED filament bulbs, more background
