The History of Creation of Conveyable Lighting Tower
Who invented the first cartable lighting tower?
This depends largely on your definition of a lighting tower. A broad definition may 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 likely 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 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 transportable 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 giant electrical lamp at each end of the auto. 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 because of adverse weather conditions.
More lately 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 portable lighting tower composed of 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 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 kind of a big development in the history of the lighting tower as this patent largely forms the root of most current day lighting towers which contain similar elements such as 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 extensive 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 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 just about 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 substantial progress has been manufactured by lighting tower manufacturers. Although the final design has sundry little from those seen in the 1980s many improvements have been made to make lighting towers easier to use and more green.
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 virtually any generator to be used to power the light heads.
The TCP Ecolite lighting tower in addition has broken new ground by exploiting intensely cost-effective lamps to reduce fuel consumption seriously, which is particularly timely seeing as global warming is starting to become a more and more plentiful concern.
