I made this dimmer circuit because I have a cheap chinese LED lamp that doesn’t have the option to dim its light. It is a simple PWM dimmer built with the well-knows 555 integrated circuit and a power ...

A modification of the current-control circuit in a low-voltage LED system allows use of a chopped supply voltage to modulate the LED intensity. The circuit prevents inrush current to the decoupling ...

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, ...

A recent discussion with Scott Brown of iWatt revealed some interesting facts about the design of IC drivers for consumer LED lighting. Although LED lifetime can reach about 20 years and the power ...

Users can easily reduce energy usage with dimmers. Dimming technology has evolved considerably over the last decade, especially in the arc discharge lamp category. What began as a device for simply ...

In general terms, dimmers are devices that vary light level (intensity) of lamps by controlling the amount of power that is delivered to the lamp. Dimming can be controlled by either manual or ...
