Led Lightbar Varieties
An LED lightbar is familiar to most people by its presence atop emergency vehicles. Since it is the light bars and sirens that warn people to move out of the way, practically everybody is familiar with these lights. But less familiar are people with the fact that there are light bars of highly varying sizes and shapes.
A large LED lightbar could be a combination of several lights. There are mega light bars that contain double lights facing towards the front, double lights facing backwards, a set of takedown lights for illuminating the vehicle in front, alley lights for lighting up the side alleys, multicolored internal lights, separate front facing and back facing lights that can be independently controlled, traffic guidance lights, and a tail indicator.
While larger light bars of various designs are being developed, there is equal emphasis on developing thin low profile LED lightbar necessary for undercover operations. Such a light bar will be extremely thin and mounted on the top of the vehicle with colorless mounting devices that hug the roof. Since LED lights do not need colored lenses, these low profile lights will become visible only when it is switched on. It will get activated instantly and will produce high intensity lights of the required colors.
While these larger and smaller light bars mainly find use in emergency vehicles, there are a lot of non-emergency situations also for which an LED lightbar is used nowadays.
There is water proof LED lightbar which can be kept immersed in water for a short length of time without sustaining any damage and will withstand getting splashed by water every day. The light bars will be coated completely with water proof material and the connectors also will be fully water proof, with a male connector and female connector on a bar. Such light bars are fixed around fountains and are used for user activated or sound activated water displays.
A water proof LED lightbar will be typically narrow and a bar that is one meter in length will have a light output of about 240 lumens. Different types of mounting clips will be available with these waterproof light bars for mounting on a chosen medium.
A slightly different type of small LED lightbar is used for under cabinet lighting and display case lighting. These are designed to be fixed at different angles to project the light down and illuminate the counter top, or to project the light up to provide the indirect lighting necessary for cove lighting. Mounting clips of different types are available for these cabinet light bars also.
A piranha LED lightbar is a light bar where the circuit is enclosed in acrylic. The lights itself will be atop the acrylic bar. The lights are typically very bright in these light bars and these are used in a variety of applications. Besides use in cabinets and display cases, a piranha LED lightbar is used in lighting larger spaces like back yards or gardens or boats, and smaller areas like a dash or deck or display counter.
Now that LED lights are being used for home lighting as well, there are no limits to the ways in which an LED lightbar can be put to use.
