MSI motherboards use light-emitting diodes to report the status of the computer. Most computers have an LED for the power and an LED for the hard drive. If the PC is turned on, the power LED glows ...

Reader Shawn wrote in with this power pickle: I have a Dell Studio Laptop. When I turn off my computer, the power-button light stays on and blinks. The only way I can stop it from blinking is to ...

Many commercial and industrial (C&I) facilities require the use of emergency power systems (EPSs) to ensure power delivery to critical loads. EPSs consist of diesel-powered generators, batteries, ...

This project is a simple universal Power LED Driver. The Power LED can be controlled by the built-in PWM signal generator or driven from an external drive signal depending on how the hardware is ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...

Texas Instruments Incorporated introduced a new LED controller with constant power regulation. The LM3447 AC/DC LED driver includes a dimmer detect, phase decoder and adjustable hold current circuits ...

In the increasingly popular world of light-emitting diodes (LEDs), an emitter’s light output per given input (efficiency), heat management, and small footprint are critical. So if you can make ...

Hi folks, I'm looking at replacing some overhead fluorescent tubes with LED tubes in our server rooms. One issue, however, is the occasional surge through the lighting system. The fluorescent bulbs ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a leading global innovator of LED products and technology, announced that it has introduced high-power LED package ...

144 LEDs total. Three sets of 48 in series connected in parallel. My problem is I don't know what value to use for R1. I'm thinking 600 ohm, but I really don't know how to calculate this. I'm making ...
