By tony ennis So nearly immediately, both capacitors are charged through the 470k caps. With no path to ground, neither LED can light. 2. Before the flashing begins, does the voltage across the caps actually decrease over time as the current through the 100k resistor 'catches up' to the positive side of t...

By matt buchanan LEDs (light emitting diodes) are different from say, an old school incandescent bulb, which heats up a filament to generate light, in that they're electroluminescent—electricity passes through a semiconductor and the movement of the electrons just lights it up. Instead of having one...

By tdg8934 Lighting and Display Solutions - LED Drivers - TLC59116 - TI.com I am concerned that this chip can only connect up to (14) I2C TLC59116 chips. That is only 14 X 16 outputs or 224 LEDs. How would I get around this? I need to have 1000's of LEDs in 16x8 modules driven by a 'smart' PWM LED driver.

By Leo Hickman The packaging should always tell you the equivalent wattage of the bulb. In general terms, CFLs use 65-80% less power than an incandescent bulb. Therefore, a CFL marked as "100W" could need as little as 20 watts of power. There are even some newer bulbs that use LED (light emitting diode) tech...

By R2-D2 Can I use just one resistor for each group of LEDs (R7, R8 and R9) instead of one for each of the six branches in the LED groups? If I need a resistor for each branch (of three LEDs), I have calculated them to be at 75Ω each. R = (1.8 volts dropped / 0.024 Amps) = 75Ω

By khowell So and his team’s blue OLED achieved a peak efficiency of 50 lumens — a lumen is a measure of brightness perceived by human eyes — per watt. That’s a significant step toward the goal of his project: to achieve white light with efficiency higher than 100 lumens per watt.

By rfaturechi@sacbee.com (Robert Faturechi) Regular bulbs have a filament inside that emits light when heated, a process that can waste a significant amount of energy in the form of heat. Strands of LED lights plug in like traditional lighting, but they stay cooler as they use most of their energy to create light.

By Wilson Rothman LED backlighting is the wave of the future for LCDs, and not just because they are "greener" than the current CCFLs. Because they can alternately dim and brighten 60 or 70 separate clusters of LEDs underneath the LCD panel, you get deeper contrast, but without losing detail in dark scenes. T...
