Traits That Contribute To The Efficiency Of Police Lights

Police lights need to be highly effective whether they are used during high speed car chases

, by highway patrol cars or law enforcement vehicles or by vehicles which are on state duty and need to get a clear way on a busy road. There are certain features that make police lighting fixtures extremely effective. The first one is undoubtedly the energy efficiency, which is important especially when the lights have to stay on for long hours. The energy efficiency helps you in avoiding bulky power supplies. Police emergency lighting fixtures are usually seen using light emitting diodes which can provide higher luminosity for the same wattage compared to incandescent, CFL or halogen lighting. The energy efficiency allows you to power the LED light bars using just a 12V DC power source with rechargeable batteries. This enhances the cost effectiveness of the LED lights, which offer a good deal with their 100,000 hour lifespan rating.

Police lights are usually designed for heavy duty handling and this can be seen in their extruded aluminum housing that is sturdy and rugged and yet lightweight, for better portability. Polycarbonate or nylon filled base is used on anodized aluminum platforms as well to provide vibration resistance to the lights. There is special encapsulation as well to make the lights weather resistant allowing you to get full utility of the lights even in the most adverse of conditions.

The Police lights available from different manufacturers have a modular design. In fact, some light bars come with LED corner and linear modules, where several different LED segments are configured together for maximum lighting output and 360-degree visibility. One of the features of this modular design is that every individual component as well as segment is individually programmable, replaceable and repairable. Besides, even if one LED segment breaks down you can be absolutely sure that the rest are still functioning. Moreover, LED lights give you additional reliability where you dont have to worry about their breaking down abruptly.

Some Police lights feature, full-fledged light bars which comprise of several varieties of lights for different functionalities. There are side marker lights, warning strobe lights, alley and flashing takedown lights and super bright LED segments. Moreover, clear, polycarbonate lens and Fresnel outer lenses are used to provide flexibility in beam angle. Chrome reflectors and diagonal mirrors are also used to provide control over the beams. You can have highly focused narrow beams created by collecting light from different LEDs and then concentrating them in one point. You can also have wider angle beams when you need greater coverage.

Police lights are also identified by their high intensity flashing. Modern police light bars use advanced technology to build in various flash patterns as well as mechanisms to easily turn on the flash patterns, lock the desired one, switch patterns or even save information about a particular flash pattern for future retrieval. The mounting hardware kit is also quite advanced to make sure you have plenty of options, while special waterproof interconnectors are provided to sync the flashing of various light heads.
