This circuit uses the Texas Instruments TPS61040 white light LED driver to provide gradual illumination at turnon and turnoff without the use of a microprocessor. White Light LED Driver With Gradual ...
Up until now the Philips Hue line has focused heavily on color-changing LEDs. The Philips Hue starter kit we reviewed last year received an excellent rating, but its three coloring-changing bulbs and ...
Over the decade, the solid-state lighting sources based on white light-emitting diodes (LEDs) has improved to overtake incandescent and fluorescent lighting types because of many advantages such as ...
Light-emitting diodes (LEDs) are better than compact fluorescent bulbs–LEDs use less energy, last longer, and contain no toxic mercury–but for general white-light illumination, they’re still far too ...
Roughly 20 percent of the electricity consumed worldwide is used to light homes, businesses, and other private and public spaces. Though this consumption represents a large drain on resources, it also ...
More than one-fifth of US electricity is used to power artificial lighting. Light-emitting diodes based on group III/nitride semiconductors are bringing about a revolution in energy-efficient lighting ...
