Fire Truck Lightbars and Some Commonly Seen Elements That Add to Effectiveness

03.03.2012 · Posted in Cars Articles

Fire truck lightbars provide an unending variety of features and accessories and it could sometimes be confusing for those picking emergency vehicle lighting equipment. However, there are certain elements which always provide that extra edge to these light bars. Top manufacturers, who back their products with quality testing and great research, are well aware of what those elements are. For example, good light bars come with a rugged base made of polycarbonate and a housing which is usually anodized or powder coated aluminium. Both these materials are lightweight and yet can take high impact, absorb it and make the LEDs inside vibration resistant. It should also be mentioned that this kind of chassis is good at heat dissipation which proves to be significant when the lights stay on for a long time. rnrnThe fire truck lightbars provide a varied range of mounting options which works in the benefit of the user. There are slide bolt mounting mechanisms, swivel bracket and suction cup mounting accessories, stainless steel straps and temporary mounting options such as powerful magnets with a significant combined pull. The mounting accessories need to be picked based on whether your needs are towards permanent mounting or temporary mounting. Temporary mounting options can be of great use when light bars need to be shared between multiple vehicles. At the same time, it should be easy enough to install or uninstall the emergency lighting equipment. rnrnThe internal design of fire truck lightbars usually shows the use of slide in lenses or Fresnel inner domes. You can choose either clear or coloured lenses or domes to enhance the effects of the beam emitted from the LEDs. On their own, the LED beams are unidirectional and cannot really give you powerful lighting. However, a lot of enhancements are in place to strengthen the beam. For example, wide angle optics and spreading filters stretch the beam along the horizontal axis. Similarly, parabolic reflectors and convex lenses are used to focus the beams when needed. In some cases, the LEDs are placed at the centre of the reflectors to fill the entire light head. Mirrored shrouds or transparent domes can then provide an aura effect to the light head, making the warning light more visible in darker conditions. rnrnSwitch panels available with fire truck lightbars add to their efficiency further. There are all kinds of switches to cope up with the different functions provided by modern fire truck light bars. There are intensity mode control switches, flash pattern control switches and push button power switches too. Illuminated panels with all the controls are very easy to operate especially under pressure. The light bars can also benefit from controls that affect the beam quality, in terms of its angle and temperature. Light bars mounted on the roof of fire engines are aerodynamically efficient so that they don
