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 ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

Here’s a simple project for your Halloween celebration. The other day while looking through our box of Halloween decorations, we noticed that the incandescent lamp in one of the jack-o’-lanterns was ...
