Anytime an emergency vehicle - ambulance, tow truck, police squad automobile, or even a fire truck for example - comes screaming past you on the highway, the blaring siren and flashing light you see is most likely a Whelen emergency LED light. Contracted by different emergency, medical, and law enforcement agencies, and Whelen LED light can be seen on many modern emergency response vehicles. But in spite of their ubiquity, the Whelen LED light isn't precisely a time honored technology. LED lights themselves are in fact a far more current invention of the previous ten years perhaps.

LEDs, or Light Emitting Diodes, have been around since the 1960s, even though their application has been for a long time limited by low-energy indicator lights together with much larger bits of technology - such as the gas or break lights on the HUD of your car. At low degrees, the energy usage of LEDs is a lot more efficient when compared with incandescent bulbs - the other well-liked way of projecting light in technological applications.

That is why for the past several decades LEDs happen to be restricted to use as small indicators for small appliances and the sort. However, a single large LED projecting a great deal of light would not be energy efficient, for this reason their constrained application for a time. Grouping a great many small LEDs together however allows a device to project a practical amount of bright light at a minimal cost of energy. This finding has proven extremely helpful to the application of sirens and emergency lighting, hence the development of the Whelen LED light.

A common application of LED lights that a lot of people are familiar with are traffic signals or stop lights. Only very, very rarely will you see a typical red, yellow, green traffic signal whose lights are each made up of a single large bulb. The energy consumption, heat generation, and brightness of such a bulb would hardly be efficient - either the bulb eats excessive energy and gets too hot, or is not bright enough. Most traffic signals are instead a densely compacted assortment of much smaller LEDs, which could project a very bright, visible spectrum of light at a cost of energy that isn't much distinctive from just one bulb, but without producing excessive amounts of heat that might become a threat.

LEDs are thence flawlessly designed for the Whelen LED light. They might come in a variety of sizes, a few as obscenely small as the head of a wooden match, as well as in various bright, vibrant colors (which usually depends on the semiconductor material used) which are perfectly suited to the color coded signals which are kept in mind during the design of a siren. The end result is a system of emergency lighting that may be bright, vibrant, easily visible, minimal on energy consumption, and at minimal risk of overheating.
