A new nanostructure gas sensor uses safe blue LED light to distinguish hydrogen, ammonia, and ethanol with 56x better ...

The traditional way to control the output of multiple LEDs is to dedicate a pulse width modulation (PWM) controller to each LED and use the controller to transform the input voltage to a current that ...

How hard could it be to turn on an LED? Connect the LED in series with an appropriate resistor and hook it up to a dc source with the correct polarity and voilà, instant LED light. Of course, you can ...

This application note gives some examples how to emulate multiple lamps using one MLX1003 LED driver. By modifying the current that is controlled by one LED driver, multiple lamps can be emulated. A ...

DETROIT -- Your next car’s headlights could be brighter and more focused, illuminating farther down the road but continually shifting to avoid shining into the eyes of other drivers. Multi-LED ...
