Although white LEDs are common in a variety of lighting applications, their 3 to 4 V forward-voltage drop makes low-voltage applications challenging. Charge pumps and other ICs are available for driving white LEDs, but they generally don't work with the low supply voltage of 1.5 V in...

Glen has written an article detailing his homebrew DMX-controlled RGB LED light: This project is a small DMX-512 controlled, color-changing RGB LED light. The light can be controlled via the DMX512 protocol or it can run a number of built-in programs depending on how the software is...

Glen Akins build a USB Stack Light Controller based on PIC16F1459 and documents the process on this personal blog. He writes: After using the PIC16F1459 to build numerous USB HID input devices including a giant keyboard, a tiny keyboard, and a big red button, it was time to see if the...

Providing up to 1,300 mW in an industry standard package, the new LUXEON IR 2720 is optimized for a variety of cost conscious infrared applications requiring high power outputs. Lumileds today introduced the LUXEON IR 2720 Line, high power emitters that set the standard for abundant...

Kingbright KPTR series, suitable for reverse mounting, makes it possible to achieve that the LED is hidden in the PCB. Naturally, manufacturing LED with a zero height is most likely unreal at the current physics status and 3D experience of the world. Nevertheless, it´s still possible...

This project includes 10 LEDs of 1W each, and provides high intensity lighting that can be used in various applications. The board is made in Arduino shield form and can be used with Arduino Uno or Mega. Each LED can be controlled individually connected to digital pins D2-D11 of...

The board consists of 8 x RGB LEDs 1W, BJT transistors on each LED, series resistor across the LED for current limiting, a hole to mount 18mm optical sensor which may be a defuse sensor for object detection with Arduino nano.  The board can be programed to create multiple RGB LED...

Dilshan Jayakody designed and build a programmable light controller that is able to turn ON and OFF a LED at predetermined time of each day. All the design files and source code related to this project are available at https://github.com/dilshan/programmable-light. The complete...
