A large percentage of LED drivers offered by many vendors use PWM (pulse-width modulation) intensity control to adjust LED brightness for a wide range of applications. In the PWM drivers, the ...

White Light Emitting Diodes (LED) replace HID lamps in street lighting system to include a dimming feature. A microcontroller of 8051 family is used to control the intensity by developing pulse width ...

LED headlights in cars require precise intensity control over lifetime and over temperature. Automotive headlight control levels typically require multiple nested closed control loops to compensate ...

This application note shows how to make use of the Maxim MAX6958/9 IC’s for driving LED’s and controlling their intensity. The LED’s can be made to blink or light up brighter than other LED’s. To view ...

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 ...

The Convention on the International Regulations for Preventing Collisions at Sea (COLREGS) governs the intensity of navigation lights, requiring a minimum intensity in candelas according to a ...

The Lambda TLED and TLED+ are stand-alone LED light sources that can be used with the transmitted light path of a microscope or in other applications with similar requirements. The basic system ...
