Different Components of Blue LED Light Fixtures
Go to: Previous Article Next Article
Blue LED light fixtures are extremely popular and useful as emergency lights used on top of vehicles such as patrol cars, heavy equipment carriers, trailers and towing vehicles. Blue LED lights are also used by medical emergency vehicles and fire fighter trucks. These LED bars usually come with a variety of components assembled together with great care. Modular design is generally preferred for the light bars particularly because it becomes easy to access every individual component when it is necessary to inspect, repair or replace them. These LED light bars are sometimes configured out of multiple LED bars or segments so that in spite of malfunctioning of one segment, there is a source of emergency warning signal to fall back to.
Blue LED light fixtures make use of 3mm, 5mm, 7mm or 10mm LEDs which have varying wattage. You can pick and choose the kind of LEDs that you need. For example, some bars have 1W LEDs arranged in split arrays or multiple rows. Some segments have the bigger and brighter 4W LEDs which can provide very impressive intensity whenever required. There are LED strobes too, which come with spare strobe tubes in different colors that can be used for bright flashy lighting. The color of the blue LED lights could be because of the elements. It could also be because of the lenses or colored filters which are used in conjunction with white LEDs. That gives greater flexibility as you can mix and match the colors of the LEDs by just changing the filters.
Blue LED light bars can also benefit from optic spreading filters, slide in and double Fresnel lenses and wide angle domes. The filters make sure that the beam is spread horizontally. The clear, polycarbonate replaceable lenses prove to be extremely useful as well. The lenses and LED elements are well encapsulated to make sure that they are protected from vibrations as well as from moisture. Weather proof LED bars can be confidently mounted externally, on the roof of the vehicle, near the front grille or bumper or close to the rear deck. In some blue LED lights, parabolic reflectors and diamond mirrors are also present to further enhance and make the most of the LED light.
A very important component in blue LED light bars is the advanced microchip or controller that is useful in altering the flash patterns depending upon the requirement. Switch boxes or panels are provided with the lighting fixtures. There is a simple cigar plug adapter that can be used to turn on the power supply. Then there are push button and slide position switches for pattern selection. 10 or 15 feet power cords, interconnector wires and waterproof, shielded cables are provided in the hardware kit along with a variety of mounting options too. Blue LED lights can be mounted using slide bolts driven through 1 inch mounting holes. A combination of swivel brackets and suction cups are used in most cases. Blue LED lights can also benefit from additional standalone strobes which provide all round lighting.
