International Rectifier has introduced the IRS2548D switched mode power supply control IC for energy efficient applications. The device is designed for high power led illumination and combines power ...

1. A Cree XM-L RGBW high-power LED can be driven by two LT3964 LED drivers for accurate 1:8192 per channel dimming. 2. Typical driver architectures offer 8-bit color resolution. Implementing a ...

As soon as I applied LED power, the brightness blinded me — much brighter than the original T20 fluorescent tube, so I knew immediately that a dimmer control was required ... not completely remove ...

The metal detector circuit is built with CD4011. Led searchlight This LED searchlight comprises a sealed maintenance-free (SMF) battery, constant voltage battery charger, six high efficiency white ...

EE and firmware developer [Enrico] had played with LEDs as a kid, burning out his fair share of them by applying too much current. With the benefit of his firmware chops, he set about creating a ...

Almost a month ago I started trying to reverse engineer an inexpensive LED color changing light bulb. With your help I’ve mapped out the circuit, and taken control of the bulb. But there’s ...

With a properly sized 15VDC supply and heatsink for the D718, you could power several LED fixtures with just one dimmer. Alternately, the circuit is small enough that you could mount several dimmers ...

As it degrades over time, it can release sulfur, which in turn can potentially corrode the LED control circuit, causing the LEDs themselves to flicker, illuminate poorly or even fail outright.
