In the last three years he has focused on products for the emerging high brightness LED market in the automotive and industrial areas. Chris holds a BSEE from the Virginia Polytechnic Institute and State University.
LEDs are inherently current-driven devices; i.e., their brightness varies with their forward current, IF. Depending on the color as well as the forward current, the LEDs' forward voltage drop, VF, varies as well. Thus, driving LEDs with a constant current is essential to achieve the desire...
These improvements consist of better color accuracy, increased brightness efficiency, and extended durability in LED items. Furthermore, the increased production scale and improved manufacturing processes in China are lowering the price of LEDs, allowing a wider range of individuals to afford them. ...
A light bulb's brightness is actually measured in lumens. And that's the big beautiful difference between LED and incandescent light bulb types - an LED uses much less energy (wattage) to produce the same brightness (lumens) as its incandescent cousin. So while LED bulbs may be more expensi...
Lumens are a measure of brightness or more technically a unit of luminous flux emitted from a lamp in all directions. The light flux falling on a surface one square foot in area, every part of which is one foot from a point source having a luminous intensity of one candela in all direct...
Now you can light up your space in any color and adjust the brightness level to suit your needs. LED light strips don’t just offer variety, they are also the most efficient form of lighting. Take a look at the chart below to see how LEDs compare to CFL (Compact Fluorescent) and ...
The brightness increases depending on theLED tube’slumen ratings. Changing your lights to LEDs will reduce the expenses of running them and give back twice the brightness. Plus, the conversion method ensures that you enjoy very efficient usage. Usually, standard LED Tubes use about 18 watts com...
