Components and Materials of LED Warning Lightbar

Whether you work in law enforcement, drive a lot off-road, or you're just interested in extra safety measures for truck driving, purchasing a full-size warning lightbar is a smart choice.


LED strips use electricity from semiconductor diodes to emit light. The diode projects light outward by radiating power. It is a common form of LED lighting but is more robust and convenient for driving applications. To be sure, caution car beacons can help divert vehicles and announce a stop for business when the road is safe or when there is an unnecessary risk. However, you should keep in mind that the use of light strips on regular roads requires DOT approval, as indiscriminate use of the lights may cause irritation and distraction to other drivers.


Ⅰ. Components of the LED warning lightbar


After all, in order to properly use and maintain this advanced tool, it is always wise to ensure a foundation of knowledge. If you're going to use something very compelling like this, it pays to understand how the said device works. This applies to individual users, business users, and even those within emergency services who want to give their staff more confidence in the tools they use. Most importantly, knowing your options can help you understand how to buy good quality items from suppliers and not be lured by inflated and unreal prices elsewhere.


For emergency led warning lightbar, it is very important to shield its components within a sturdy housing. This must also be immune to light debris, such as snow or hard soil, and weatherproof. It must also be completely transparent to ensure maximum brightness.


Ⅱ. Two commonly used materials for LED warning lightbar shells——aluminum and polycarbonate.


Heavy duty aluminum is an excellent material for LED housings. Because it is so lightweight, it provides a cohesive visual and paintable housing that gives the light bar chassis the aesthetics of your vehicle and can be protected by an epoxy coating. This prevents rust and marks from occurring and is ideal for severe weather conditions.


Aluminum is also an incredible heat sink, which at first glance doesn't seem all that important when considering LED lighting. But on hot days, that means increased protection. Aluminum is also odorless and non-toxic, meaning it's a safe and secure enclosure solution with enough folded tensile strength to keep your LED caution light bar as safe as possible.


Polycarbonate is a very unique plastic. It is made of clear resin and has an extremely transparent and up to 90% transparent casing. Not only that, but thanks to its tensile strength, it can withstand severe impacts, harsh weather conditions, and is very easy to clean. This means that even with the brightest lens behind the case, the polycarbonate is able to transmit it with almost no impedance.


It's also lighter compared to the aluminum shell, which makes a difference when considering the handling of a particular vehicle. For some people who might not make much of a difference, but it's easy to imagine how important this is to full emergency services. Not only that, but the strength-to-weight and strength-to-stiffness measurements are virtually the same in most applications.


As demonstrated below, polycarbonate is also an amazing resin plastic for high quality led warning light housings. This means that on a macro scale, when combined with this, you get twice the protection of this strong and reliable coating. If you can trust a material to protect your most sensitive LED light sources, you can be sure it will retain its usefulness in elongated, aerodynamic and streamlined LED warning light bar housings.
