Many LEDs, those highly popular Light Emitting Diodes, die prematurely because they are improperly used by people who know little to nothing about electronics. Let's try to stop the massacre. An LED ...

Knowing how to calculate an LED current limiting resistor is one thing, taking into account all other sorts of parameters as well is another. In Part 1 you learned how to calculate a current limiting ...

Scarcely a lighting application exists that designers have not considered converting to solid-state lighting, especially as LEDs by leaps and bounds improve both the quantity and the quality of their ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

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 ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words the currents in the branches of a parallel circuit add up to the ...
