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 ...

If an LED pilot lamp is used in battery powered circuits, it will unnecessarily consume power. This circuit lights an LED at power on and after one minute it will turns off. The circuit uses a Zener ...

The new driving force for the growth of white LED lighting is quite simple: lower energy consumption and much lower energy bills. By some calculations, the transition from traditional incandescent and ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

Infrastructure projects like the Tokyo Gate Bridge are now turning to LED lighting because of its economical and environmental advantages. But these devices still need the right current-limiting ...
