“L-E-D”. When it comes to lighting, you’re hearing these three letters over and over again… you see it posted all over lighting websites, and its starting to bug you. It seems to be an exciting new trend…some kind of new innovative light…but you have no idea what it is. You’d like to know what everybody’s talking about- what’s all the rage?
LED’s – Light Emitting Diodes – Simply put, LED’s are diodes that…(huh?) hang on, I’ll explain: a diode is the simplest sort of semiconductor device. (what’s that?) wow, you’re impatient: A semi-conductor is a material with the ability to conduct electrical current. Basically, instead of emitting light from a vacuum (as in an incandescent bulb) or a gas (as in a CFL), LED emits light from a piece of solid matter, its semi-conductor. Stated very simply, an LED produces light when electrons move around within its semiconductor structure.

They tell you when to stop and go. They have ruled your driving, saved your life countless times, and that little red man made you wait around till you were able to cross the street. That’s right – the red, yellow and green on the traffic lights are Led lights right in front of your nose. In fact, Light Emitting Diodes have been around for some time, conceptualized in 1907. However, it wasn’t until the 1960s that practical applications were found and LED’s were first manufactured. LED used to be used exclusively for traffic signals, brake lights and headlights on luxury cars, and indicator lights on appliances. You probably didn’t even know that LED lights were lighting up your digital clocks, flashlights and telling you when you’ve got a new voice message on your cell phone. Expensive at the start, as applications grew, benefits were discovered and manufacturing costs went down. According to the American Lighting Association (ALA), lighting manufacturers have invested considerable time, effort and research into adapting this super energy-efficient technology for household use. The technology has advanced enough to win approval from the government’s popular and well-respected Energy Star® program.
