Anytime an emergency vehicle – ambulance, tow truck, police squad car, or even a fire truck for example – comes screaming past you on the road, the blaring siren and flashing light you see is likely a Whelen LED bright light. Contracted by various emergency, medical, and law enforcement agencies, and Whelen LED light sometimes appears on many modern emergency response vehicles. But in spite of their ubiquity, the Whelen LED light isn’t just a time honored technology. LED lights on their own are in reality a far more new creation of the past ten years perhaps.
LEDs, or Light Emitting Diodes, have been around since the 60s, though their application has long been for a long time limited by low-energy indicator lights included in bigger components of technology – as an example the gas or break lights on the HUD of your car. At low degrees, the energy usage of LEDs is much more efficient than incandescent bulbs – the other popular method of projecting light in technological applications.
That is why over the past several decades LEDs are actually restricted to use as small indicators for small appliances and the sort. However, just one large LED projecting a large amount of light would not be energy efficient, consequently their limited application for a time. Grouping a great many small LEDs together however allows a gadget to project a practical amount of bright light at a marginal cost of energy. This finding has proven extremely beneficial to the application of sirens and emergency vehicle lights, hence the development of the Whelen LED light.
A popular application of LED lighting effects that most people are acquainted with are traffic signals or stop lights. Only very, quite rarely can you see a common red, yellow, green traffic signal whose lights are each comprised of a single large bulb. The energy consumption, heat generation, and brightness of such a bulb would simply not be powerful – either the bulb uses a lot of energy and results in being too hot, or is not bright enough. Most traffic signals are alternatively a densely compacted variety of much smaller LEDs, that can project an extremely bright, visible spectrum of light at a cost of energy that isn’t much distinctive from an individual bulb, but without producing excessive amounts of heat that might become a danger.
LEDs are thence flawlessly suited 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, and in many different 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, conveniently visible, small on energy usage, and also at minimal risk of heating up.
