Here is a simple and powerful LED circuit that can be operated directly from the AC 100 volt to AC 230 Volts mains supply. The circuit can be used as mains power locator or night lamp etc.. The ...
Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...
Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...
Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...
HB (high-brightness) LEDs require a large amount of current to operate. When driving HB LEDs from a voltage source, you can set the required current with a suitable series resistor. If the voltage ...
Evil Mad Scientist Labs brings us this easy to make LED blinking circuit. The idea is to put a LED in series with a small blinking incandescent bulb from a string of Christmas lights. The bulb has an ...
Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...
You’ve probably heard of light-emitting diodes, a type of energy-efficient light. While they’re good for practical reasons—say, illuminating a room or a passageway—they can also add a little bling to ...
