What is LED Technology?
"A light-emitting diode (LED) is a semiconductor diode that emits incoherent narrow-spectrum light when electrically biased in the forward direction of the p-n junction, as in the common LED circuit. This effect is a form of electroluminescence.
The LED is usually a small area source, often with extra optics added to the chip that shapes its radiation pattern. LED's are often used as small indicator lights on electronic devices and increasingly in higher power applications such as flashlights and area lighting. The color of the emitted light depends on the composition and condition of the semiconducting material used, and can be infrared, visible, or near-ultraviolet. The LED can be used as a regular household light source."
LED lighting qualities outmatch conventional lighting undisputedly. The durability and lenght of useful life (LED lights have no fragile glass, no delicate metal filament) of LED lighting far exceeds those of conventional light bulbs. LED lights also use electricty far more economically.
LED lights are very small in size, light quickly and generate almost no heat.
These are just some of the qualities that have proven the LED lighting solutions as superior to older convenyional solutions and so in the recent years the use of LED lighting has become increasingly wide spread.
Infact LED lighting is often found to be in fact the only suitable option in many cases , where the conditions are simply too demanding for other solutions.
Today LED lighting applications include for example:
- Street lights
- Giant video screens
- Traffic lightst
- Electronics and toys
- LCD Televisions
Lately LED lighting has become very popular in Machine Vision sytems used by various industries to inspect and measure products and components.
