Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

In Part 1 of this two-part series, “Creating Uniform LED Luminescence in RGB Displays”, the discussion focused on dot correction. This design technique is used for managing individual pixel brightness ...

The GLCD 30 series of universal-input, constant-current 30-W LED drivers offers three-way dimming: 0 to 10 V dc, pulse-width modulation, and 10- to 100-kΩ resistance external dimming control. The GLCD ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of generating a ...

Light-emitting diodes have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...

A UK manufacturer has invented the world's first commercially available led driver that can control the led current from one millionth of an Amp to over 2.1 Amps in a single output stage. According to ...
