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 ...

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 ...

Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Typically, designs perform this task by issuing pulse widths and clocks of differing durations and employing multiple ...

Supertex’s HV9925 is optimized for driving multiple-LED strings in offline applications such as decorative lighting and low power lighting fixtures. Supertex’s HV9925, a LED driver IC with adjustable ...

Driving an LED and making it flash is probably the first project that most people will have attempted when learning about microprocessor control of hardware. The Arduino and similar boards have an LED ...

LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

The backlighting system of MacBook Pro keyboards could be upgraded to include TrueTone capabilities, with Apple examining the use of multiple LEDs per key to make the light seem even despite changes ...

If you want a light that helps illuminate your kitchen or living room, this lamp is it.

Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation. LED and OLED lighting, which is generally called solid-state lighting (SSL) ...
