Technology is always continuing to grow and change over the years, leaving us in the wake of new lingo to learn and devices to discover. Over the past several years, LED has become embedded in the laymen vocabulary as more and more people come to recognize its uses in the modern world. As many already know, LED stands for Light Emitting Diode and most of us can even point out the physical differences between LED and traditional incandescent bulbs. However, not everyone can explain how these bright bulbs came to be or just how an LED display works.
The earliest LED lighting has been traced all the way back to the early sixties, when the very first remote controls for televisions were being created. The range of these bulbs were limited to only red in color, which is why they were only used within remote control circuits for several years to follow. Nowadays, LEDs are available in practically every primary and secondary color recognized by the human eye. In fact, LED lighting has extended beyond visible wavelengths, and can also be detected in ultraviolet and infrared wavelengths as well.
Visible Wavelength – This is the most basic form of light wavelength and includes everything that is visible to the human eye. All of the light that we see from day to day are a part of this particular wavelength and tend to be the easiest to create because it is the simplest to understand. Though not all known colors can be created in lighting because it requires a more complex combination of multiple wavelengths. Many shades of purple and pink are not easily created this way.
Ultraviolet Wavelength – This refers to a wavelength that is much shorter than visible light, but longer than x-ray. Because it travels beyond visible light, this particular light is able to emit ultraviolet rays and we most often see them used in form of a black light to be used in tanning beds.
Infrared Wavelength – This type of light encompasses invisible radiant energy, which most of us familiarly refer to as thermal energy. Then radiant energy from the sun arrives in our atmosphere in infrared form, and is generally associated with heat. This type of wavelength is used to gather light in such a way to perfect night-vision and is typically used in industrial, scientific and medical applications.
Not only are LEDs used across all light wavelengths, but are also considered for their highly energy efficient functions. Compared to traditional incandescent light bulbs, LEDs can use far less electricity and last up to ten times longer; all while emitting a much brighter light in appearance. Many companies are switching their animated display screens with LED lighting in order to maximize profit and efficiency of their business.
