How to design LED streetlamp driver circuits In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED ...

Many equipment manufacturers prefer protection circuits combining resettable overcurrent protection devices with upstream fail-safe protection. In this example, R1 represents a ballast resistor used ...

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 colorful back led aquarium lights gives natural appearance to the Aquarium tank. The Aquarium Led Lighting circuit automatically turns on at sunset and gives changing White, Blue and Green color ...

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most ...

Finally, they showed that when the circuit was deposited onto a polymer substrate, its performance remained stable even when bent to a radius of 15mm – confirming its flexibility. Thanks to these ...

Then, the metal ends of the lights are cut and shaped. Like the string, the LED light bulbs are also dipped in flux. The bulbs are then finally soldered with the wire.
