There are so many factors that go into a light; it’s not just the LED. The driver circuit, mechanical design, ergonomics, the user-interface; they all have a little story.

Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

This design describes how to light a string of LEDs of any color from a 1.5-V cell using just a few inexpensive components. The circuit (see figure) forms a self-oscillating, unregulated step-up ...

A LED light pipe is an optical fiber or a solid transparent plastic rod for transmitting light from an LED mounted on a printed circuit board (PCB) to the user interface. Light pipes transmit up ...

This custom circuit board picks up some of the pieces from a wall wart to drive a high-power LED. The basic concept is to keep the high-voltage components and swap out the low voltage ones for ...
