Man is a visual creature, and gains most of the information needed to survive and thrive through his eyes. Modern man requires the ability to illuminate the darkness in order to maintain the lifestyle of current society. When a crisis, such as an earthquake or extreme weather occurs, the use of LED emergency light bars can make a life or death difference.
Of all the inventions which have propelled civilization forward in the technological era, the incandescent bulb was perhaps the most significant and least heralded. Without the ability to illuminate the night, life would be much different than it is now. The impact on economies alone would be dramatic if all nighttime activity was restricted or eliminated due to the absence of illumination.
The importance of being able to artificially illuminate the world can not be overestimated; life as we know it would not be possible without this extraordinary capability. Continuing advances in the fields of science paved the way for an alternative way to produce lumens without the traditional use of incandescent bulbs. The emitting diode is not only a new method of illumination, but in many ways a superior one.
Just as digital photography and computers began their, the origin of emitting diodes owes its creation to a discovery in the early part of the 20th century. An English scientist with the Marconi company by the name of Joseph Round was the first to describe the effects of electroluminescence. This property would be experimented with for more than half a century before becoming a working product.
Once the discovery of production in the visible range was made, production moved forward rapidly, with emitting diodes rapidly outperforming their incandescent cousins. The amount of energy used to power an emitting diode in comparison to that of a filament bulb was much lower. The could be produced in very small sizes, making them far more flexible in application. They were durable both in resistance to impact and in lifespan.
The price of these devices, as with almost every new device, was cost prohibitive for commercial profitability, but this problem was rather quickly overcome through new materials. While the price per bulb may still be higher, the lifetime cost of the product is much smaller due to increased durability. The lifetime of a typical incandescent bulb is between 1,000 and 2,000 hours, while the typical emitting diode bulb boasts a lifetime the 25,000 to 100,000 hours.
In some case the new product was an instant win, such as in refrigerators and freezers and in indicators for everything from automobiles and airplanes, to stereos and appliance clocks. The longevity and durability of these products often meant they would outlast the product on which they served. They are especially well adapted to use outside in traffic lights, advertising and information signs.
Emitting diodes last longer, are more durable and amazingly efficient, and their small size allows for more applications. New research has developed the capability of producing flexible screens. For now, such uses as in LED emergency light bars show their importance in life preservation during emergencies and pave their way as the future in illumination.
