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. A detailed definition could include something as easy as a candle or primitive torch placed on a tall mast to cast light over a large area, such a device has likely been in use since the Stone Age.
In more current history it’s un-clear as to when the modern lighting tower was invented. Researching patent applications indicates that machines not dissimilar to today’s lighting towers were being designed in the 1930s.
A patent from 1932 shows what might be the first machine of its kind filed in US patent 1934576 and is named as a Portable floodlighting unit for airports.
The patent describes a frame with four wheels at each corner ( allowing the machine to be towed ), a generator powered by an engine and one massive electrical lamp at each end of the auto. The machine is meant 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 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 current day lighting towers.
The US patent 4181929 describes a portable lighting tower composed of a base frame ( which contains an engine and generator ) and a vertical, extending, hydraulic mast with 2 electrical lamps at the upper end. The unit doesn’t 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 high winds.
This is quite a significant development in the history of the lighting tower as this patent mostly 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 subsequent 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 frame with 4 wheels to hold the generator and engine and 2 folding telescopic masts at opposite corners of the frame that each hold a cluster of electric lamps. The design also permits for the masts to be revolved enabling finer control over the area of illumination. By offering 2 masts the light tower also allows for illumination over just about all sides of the machine. This is not like previous light towers which generally offer illumination on just one side of the machine.
Since 1980 considerable progress has been manufactured by lighting tower manufacturers. Though the overall design has varied tiny from those seen in the 1980s many enhancements have been made to make lighting towers simpler to use and more environmentally friendly.
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 virtually any generator to be used to power the light heads.
The TCP Ecolite lighting tower in addition has broken new ground by utilising intensely cost-effective lamps to reduce fuel consumption significantly, which is particularly timely seeing as global warming is beginning to become a more and more prevalent concern.
