The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

Four New Jersey cities have begun testing new street lamps powered by light-emitting diodes. The new LED lamps are expected to reduce energy consumption significantly, have a longer life expectancy ...

This circuit can be used to test up to three LEDs at once, connected in series. You can easily increase that number by using a higher supply voltage. If you do so, you should allow 2.7 V for each ...

If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, ...

The global market for high-brightness and high-power LEDs is forecast to reach $27.5 billion by 2024, with much of the growth coming from the automotive sector, where demand is growing at more than 10 ...

The diode is a fundamental component you must understand if you want to grow your electronics prowess. So today, we’re going to take a quick look at what a diode is, then look at 4½ uses for a diode ...

Advances in the power output of light emitting diodes (LEDS) have allowed a LED light curing unit (LCU) with an 8 mm diameter light guide tip to achieve a similar depth of cure in a camphorquinone ...
