Led drivers

This Automotive LED Driver Circuit immediately turns on the LEDs when there is no AC power supply. The normally open (N/O) terminal of the

In this tutorial, we are going to make an "NCR320Z LED Driver". An LED driver is an electrical device that regulates power to an LED or a

LED drivers have so many different types and variations that it can seem a little overwhelming at times. So lets take a look at LED drivers in depth.

This is my project for handmade flashlight when using 10W High Power LED voltage 12V DC. Indeed, by using this LED light produced is very b...

The increased number of complaints from the readers regarding burning LEDs associated with my earlier posted transformerless 1 watt LED driver circuit, compelled me to solve the issue once for […]

I was searching for a LED driver that can also act as dimmer for my 10 watts LEDs and found the PT4115 IC which is kind of interesting. It operates from

Pulse Width Modulation (PWM) is basically the method that is used to reduce the average power of an electrical signal.

High Power LED Driver Circuits: High-power LED's: the future of lighting! but... how do you use them? where do you get them? 1-watt and 3-watt Power LED's are now widely available in the $3 to $5 range, so i've been working on a bunch of projects lately that use them. in the pro…

Power LED's - Simplest Light With Constant-current Circuit: Here's a really simple and inexpensive ($1) LED driver circuit. The circuit is a "constant current source", which means that it keeps the LED brightness constant no matter what power supply you use or surrounding environmental conditions you subject…

The current limiting circuit shown in the diagram , especially as the drive power LED driver , this circuit can be used ... Easy to use and inexpensive , keepin
