Fairchild Semiconductor has introduced a programmable LED blinker, the FAN5646, which is designed to eliminate the need for a microprocessor to be in continuous operation mode. The FAN5646 enables designers of mobile handsets, ultra-portable devices, consumer products and industrial/embedded systems to implement a blinking LED solution that can easily be programmed to create an enhanced visual experience.
With proprietary single-wire digital interface, the FAN5646 can be programmed with a unique LED blink rate and pattern. When the FAN5646 is enabled it will continually play these LED blink patterns until commanded by the microprocessor to stop. Common approaches for solving this challenge include connecting the LED to an LDO regulator or a FET plus a lithium ion battery. Both of these implementations require a microprocessor to be programmed with a blinking pattern, draining battery life since the microprocessor needs to be continually operating to maintain this pattern.
Demonstrating that LED lighting is now viable for large-scale exterior applications, Philips Color Kinetics announced Monday two new floodlights with light output of more than 8,500 lumens - a first in high-quality exterior LED floodlighting.Expanding the ColorReach Powercore product line, new Reach Powercore and iW? Reach Powercore LED high bay lights can dramatically accentuate building exteriors and landmarks with a choice of high-quality white or fixed color light, while at the same time reducing energy consumption and maintenance. It offers an alternative to traditional metal halide sources, providing more lumens of output (over 8,500 lumens at 2700 K; over 11,000 lumens at 4000 K) and unparalleled light projection (over 700 feet at 2700 K; over 800 feet at 4000 K) than any other competitive light fixture. This powerful fixture represents the next generation in exterior illumination.
