A new LED driver features temperature management control and the addition of an online design environment to support it. The LM3424, a member of the PowerWise energy-efficient product family, drives ...

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.

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...

This application note presents a reference design for driving high brightness LED (HBLED) using Z8 Encore! XP® F1680 series of microcontroller and MXHV9910 off-line HBLED driver of IXYS. The document ...

The circuit is divided into two portions for easy understanding: Logic control (Figure 1) and LED driver (Figure 2). The circuit is controlled by a momentary push switch. Until SW1 is pressed, the ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

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 ...

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 ...

UP150R, a slim RGB LED panel delivering 20,400 lux at 1 m, 180 W power draw, V-mount support, and modular expansion.
