The History of Creation of Portable Lighting Tower
Who invented the first portable lighting tower?
This depends largely on your definition of a lighting tower. A detailed definition might include something as simple as a candle or primitive torch placed on a tall mast to cast light over a big area, such a device has probably been in use since the Stone Age.
In more recent 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 1st machine of its kind filed in US patent 1934576 and is named as a Portable floodlighting unit for airfields.
The patent describes a framework with 4 wheels at every corner ( allowing the machine to be towed ), a generator powered by an engine and one large electrical lamp at each end of the auto. The machine is intended 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 because of harsh weather conditions.
More recently in 1980 a US patent 4181929 was filed for a Portable illuminating tower that illustrates a much closer resemblance to present day lighting towers.
The US patent 4181929 describes a conveyable lighting tower composed from a base frame ( which contains an engine and generator ) and a vertical, extending, hydraulic mast with two electric lamps at the upper end. The unit does not permit towing but instead is lightweight 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 quite a significant development in the history of the lighting tower as this patent principally forms the basis of most current day lighting towers which contain similar elements such as a base that stores the engine and generator together 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 a solution to provide more in depth illumination. The US patent 4220981 describes a frame with four wheels to hold the generator and engine and two folding telescopic masts at opposite corners of the framework that each hold a cluster of electrical lamps. The design also allows 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 nearly every side of the machine. This is not like prior light towers which sometimes offer illumination on just one side of the machine.
Since 1980 substantial progress has been manufactured by lighting tower makers. Though the final design has sundry little from those seen in the 1980s many improvements have been made to make lighting towers better 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 permits almost any generator to be used to power the light heads.
The TCP Ecolite lighting tower has also broken new ground by using highly cheap lamps to reduce fuel consumption significantly, which is particularly timely seeing as global warming is becoming a more and more common concern.
