This module introduces Pulse Width Modulation (PWM) techniques for Python on the Raspberry Pi. Subsequently, by using PWM we can modify the brightness of an LED without having to change a resistor.

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

Advanced Analogic Technologies' AAT1231 is a high frequency, high efficiency inductive boost dc-dc converter for controlling white LEDs in portable systems operating from single-cell ...

Advanced LED lighting arrays can spectrally tune their output wavelength to highlight different features and defects in captured images. The capability enables a single light fixture to quickly adapt ...

From 3D movie screens to augmented-reality devices, many modern technologies rely on our ability to manipulate light. Doing ...

Infineon Technologies AG has expanded its LITIX Power family with a dual-channel, stand-alone DC/DC controller. The company claims the new TLD6098-2ES is the first product that can drive a full LED ...

There are a number of ways to efficiently and elegantly limit an LED’s brightness, but [Tommy] found that using a light pipe or diffuser can integrate better with a device, especially when the device ...

In an article published in Optics Letters, researchers from The University of Osaka announced a new LED design that may help ...
