The History of Invention of Cartable Lighting Tower
Who invented the first cartable lighting tower?
This depends principally on your definition of a lighting tower. An extensive definition could include something as straightforward as a candle or primitive torch placed on a tall mast to cast light over a big area, such a device has doubtless 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 reveals 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 movable floodlighting unit for airfields.
The patent describes a frame with 4 wheels at each corner ( allowing the machine to be towed ), a generator powered by an engine and one giant electrical lamp at every end of the auto. The machine is designed to be used to provide on-demand lighting of alternative landing sites at airports on occasions when the main landing areas are out of use due to harsh weather conditions.
More recently in 1980 a US patent 4181929 was filed for a Portable illuminating tower that illustrates a much more close similarity to modern day lighting towers.
The US patent 4181929 describes a conveyable lighting tower consisting of a base frame ( which contains an engine and generator ) and a vertical, extending, hydraulic mast with two electrical lamps at the higher end. The unit does not permit towing but instead is light and compact enough to be simply transported. The design also includes jack legs that are now common place on all lighting towers to guarantee stability in strong winds.
This is quite a big development in the history of the lighting tower as this patent principally forms the root of most present day lighting towers which contain similar elements like a base that stores the engine and generator with an extending hydraulic mast that supports the luminaries.
The next patent was filed later on in the same year of 1980 but was for an answer to provide more in depth illumination. The US patent 4220981 describes a chassis with 4 wheels to hold the generator and engine and two folding telescopic masts at opposite corners of the chassis that each hold a cluster of electric lamps. The design also permits for the masts to be rotated enabling finer control over the area of illumination. By offering 2 masts the light tower also allows for illumination over nearly every side of the machine. This is unlike prior 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 overall design has varied small from those seen in the 1980s many improvements have been made to make lighting towers easier to use and more environmentally friendly.
The Hylite lighting tower from Taylor Construction Plant includes Adjustabeam technology which permits the user to adjust the direction of each lamp from the ground. The TCP Hylite also has a flexible frame design which allows just about any generator to be used to power the light heads.
The TCP Ecolite lighting tower has also broken new ground by using intensely economical lamps to reduce fuel consumption seriously, which is particularly timely seeing as global warming is beginning to become a more and more common concern.
