The History of Invention of Portable Lighting Tower
Who invented the first cartable lighting tower?
This depends mostly on your definition of a lighting tower. An extensive definition might 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 probably 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 first 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 4 wheels at every 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 closer similarity to modern day lighting towers.
The US patent 4181929 describes a conveyable 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 higher end. The unit does not permit towing but instead is lightweight and compact enough to be simply transported. The design also includes jack legs that are now common place on all lighting towers to ensure stability in high winds.
This is quite a big development in the history of the lighting tower as this patent largely forms the basis 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 next patent was filed later on in the same year of 1980 but was for an answer to provide more intensive illumination. The US patent 4220981 describes a framework 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 electrical 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 virtually all sides of the machine. This isn’t like previous light towers which generally offer illumination on only 1 side of the machine.
Since 1980 considerable progress has been manufactured by lighting tower manufacturers. Although the final design has sundry little from those seen in the 1980s many enhancements 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 allows the user to adjust the direction of each lamp from the ground. The TCP Hylite also has a flexible chassis design which permits just about any generator to be used to power the light heads.
The TCP Ecolite lighting tower in addition has damaged new ground by exploiting intensely cheap lamps to reduce fuel consumption seriously, which is especially timely seeing as global warming is becoming a more and more prevalent concern.
