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-based bulbs that replace their incandescent counterparts require a significant amount of engineering (Fig. 1). In the 60 W range the LED driver board can take up about 15% of the overall cost of ...
