The History of Creation of Conveyable Lighting Tower
Who invented the 1st cartable lighting tower?
This depends mostly on your definition of a lighting tower. An extensive definition may include something as easy as a candle or primitive torch placed on a tall mast to cast light over an enormous area, such a device has likely been used since the Stone Age.
In more recent history it’s un-clear as to when the modern lighting tower was invented. Researching patent applications suggests that machines not dissimilar to today’s lighting towers were being designed in the 1930s.
A patent from 1932 shows what could be the 1st machine of its kind filed in US patent 1934576 and is named as a Portable floodlighting unit for airports.
The patent describes a framework with four wheels at each corner ( allowing the machine to be towed ), a generator powered by an engine and one large electrical lamp at every end of the vehicle. The machine is designed to be used to provide on-demand lighting of alternative landing sites at airfields on occasions when the main landing areas are out of use due to adverse weather conditions.
More lately in 1980 a US patent 4181929 was filed for a Portable illuminating tower that illustrates a much nearer similarity to present day lighting towers.
The US patent 4181929 describes a conveyable lighting tower composed from a base frame ( which has an engine and generator ) and a vertical, extending, hydraulic mast with 2 electric lamps at the upper end. The unit doesn’t permit towing but instead is light and compact enough to be easily transported. The design also includes jack legs that are now common place on all lighting towers to guarantee stability in gusty winds.
This is kind of a significant development in the history of the lighting tower as this patent mostly forms the foundation of most modern day lighting towers which contain similar elements like a base that stores the engine and generator along with an extending hydraulic mast that supports the luminaries.
The subsequent patent was filed later on in the same year of 1980 but was for a solution to provide more intensive illumination. The US patent 4220981 describes a framework with 4 wheels to hold the generator and engine and two folding telescopic masts at opposite corners of the framework that each hold a cluster of electric lamps. The design also permits for the masts to be rotated enabling finer control of the area of illumination. By offering two masts the light tower also allows for illumination over nearly every side of the machine. This is unlike previous light towers which often offer illumination on only one side of the machine.
Since 1980 substantial progress has been manufactured by lighting tower makers. Though the final design has sundry small from those seen in the 1980s many enhancements have been made to make lighting towers simpler to use and more green.
The Hylite lighting tower from Taylor Construction Plant includes Adjustabeam technology which allows the user to adjust the direction of each lamp from the ground. The TCP Hylite also has a flexible frame design which permits just about any generator to be used to power the light heads.
The TCP Ecolite lighting tower has additionally broken new ground by utilising highly cost-effective lamps to reduce fuel consumption seriously, which is particularly timely seeing as global warming is starting to become a more and more common concern.
