Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED lighting’s many advantages simply cannot make up ...

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 have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...

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 ...

The typical low-voltage (24 V) lighting system uses a two-wire cable to connect the lamps to the off-line power supply, often located at some distance from the lamps. These systems can control lamp ...
