There are extremely high powered LEDs out there, and most of the ‘creative’ uses of these are extremely high-powered flashlights, complete with heatsinks, forced air cooling, and beefy power supplies.

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Adding to the ever growing list of Ardunio watches being created a new LED Arduino watch has been created that is powered by a supercapacitor. The watch has been featured over on the Hack A Day ...

I was searching for a LED driver that can also act as dimmer for my 10 watts LEDs and found the PT4115 IC which is kind of interesting. It operates from an input supply between 6V and 30V and provides ...

Fig 1. Single 1-W LEDs can serve as high-power, high-brightness devices. Fig 2. Certain LED applications fall into a gray area where low-power and high-power components both can fit the bill. However, ...
