Cooling strategy for LED filament bulb utilizing thermal radiation cooling and open slots enhancing thermal convection

Abstract

As a novel replacement of conventional light sources, LED filament bulb has gained popularity recently due to its long lifetime, low cost and high energy efficiency. However, the bottleneck in LED filament development is thermal management of the whole bulb and consequential degradation of light output performance. The potential cooling strategies include… (More)
