subject: What Makes The Emergency Lightbars Different From The Regular Lighting Solutions? [print this page] The invention of the electric bulb by Thomas Alva Edison put an end to darkness. Through the years, the concept of lighting has improved in leaps and bounds. Today, there are lighting solutions not just for homes and offices, but also for vehicles too. The advent of the light emitting diode technology revolutionized the lighting solutions industry. This industry which heavily relied on the filament to produce light breathed a sigh of relief when the LED technology came into existence. Though the lights with filaments did emit bright light, there were a couple of major drawbacks associated with them. One of the drawbacks was that these lights would burn out easily and therefore had to be replaced very often, which in turn increased the costs. Another drawback was the energy consumption.
Only 20 percent of the electrical energy would get converted into light energy in these lights. These lights were used for emergency vehicles as well, but with the emergency lightbars made of LED foraying into the market, the ones with filaments have disappeared into oblivion. These lightbars, in addition to lighting solutions such as emergency strobe, play an important role when used in emergency vehicles and police cars.
The first aspect that differentiates the emergency lightbars and emergency strobe made using the LED technology from other lighting solutions is their energy efficiency. These lights have the ability of work for long hours at a stretch without draining the vehicle's battery of all its charge. In regular lighting solutions, only 20 percent of the electrical energy gets converted into light energy. The other 80 percent goes towards producing heat energy to heat up the filament which then produces the light. Therefore, this type of light proved to be a drain on the resources. However, this was not the case in terms of LED lights. Over 80 percent of the electrical energy supplied to LED lights are converted into light energy, while the remaining 20 percent is lost in the form of heat energy. This clearly substantiates the fact that the LED lighting solutions promote energy conservation as well.
Another attribute that differentiates the regular lighting solutions from the LED emergency lightbars and emergency strobe is the presence of a magnifying glass in the overall design. The bright light emitted by lighting solutions used in emergency vehicles is bright and visible from a distance. This is because of the presence of a magnifying glass which magnifies the light produced. Therefore, the presence of these vehicles can be detected from a distance. This helps that other vehicles and people on the roads to make way for them so they can move along without facing any obstacles.
The third aspect that differentiates the emergency lightbars and emergency strobe from other lights is the presence of a tiny inbuilt heater. The role of this tiny heater is to prevent the formation of snow and icicles on the light so they can function effectively during harsh winters as well. These heaters melt away the ice easily and helps the lights function efficiently.
