Connecting to the web via LEDs: Li-Fi

Connecting to the Internet is best done through copper wire or high-speed wireless connections. Not many are aware of an additional method – using light beams. This is accomplished not by the usual optical fiber stuff, but by using LEDs. Communication with lights is nothing new - it has been done before. The Scottish scientist, Sir Alexander Graham Bell had invented an arsenal of instruments for communication and these included Photophones. The first instruments to use light for communication Read more [...]

Battle the Sun with a 21W LED and a Raspberry Pi

Lighting up an LED or an array of LEDs and controlling their brightness is a simple affair with the tiny credit card sized single board computer popularly known as the Raspberry Pi or the RBPi. The RBPi runs a full version of Linux and you can use it to drive an array of bright LEDs with it. If you construct it like Jeremy Blum did - he put up the LEDs on his graduation mortar board and wore the RBPi on his wrist on his graduation day - you can be sure of getting a lot of excited remarks from friends Read more [...]

What is LED EOS failure?

LEDs, being semiconductor components, are susceptible to failure if overstressed electrically. This is true regardless of the manufacturer and electrical overstress or EOS is the leading cause of failure of LEDs. In fact, LED components are subject to transient conditions that can cause EOS and subsequently result in a catastrophic failure. Like all semiconductor components, LEDs too have their maximum specifications of voltage, current and power. An exposure beyond the maximum current or voltage Read more [...]

ByteLight LEDS provide location based service

Not so very long ago, the friendly neighborhood supermarket had a security guard who would greet you in recognition and the store assistants could guide you since they knew what you usually bought. However, the introduction of huge shopping malls with their multiple floors has done away with anyone able to recognize even frequent customers, making the whole affair of shopping completely impersonal. However, things are about to change. GE Lighting and ByteLight are harnessing the next generation Read more [...]

Are OLEDS better than LEDS?

Chances are, you still own a TV that is bulky, has a picture tube and is kept on a table. Well, with advancing technology, TVs have become slimmer and lighter, can hang on the wall and do not have a bulky picture tube. The new TVs have an LCD or a Liquid Crystal Display in place of the earlier picture tube. Now, unlike the picture tube, LCDs have no light of their own, and have to be lit with a backlight. Until recently, most LCD TVs were backlit with plasma discharge tubes or CCFL lamps. The Read more [...]

West Florida Components in the community making LED Throwies

West Florida Components was recently invited to participate in a science experiments fair held in conjunction with the USF Education Department. Each business staffed a booth where elementary school aged kids along with their families could conduct science experiments. The community event was an opportunity for families to enjoy and see the benefits of science in a fun atmosphere. The West Florida Components station was one of about 18 stations at which participants could interact and have Read more [...]
