The History of Creation of Cartable Lighting Tower
Who invented the 1st conveyable lighting tower?
This depends largely on your definition of a lighting tower. A broad definition might include something as straightforward as a candle or primitive torch placed on a tall mast to cast light over an enormous 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 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 movable floodlighting unit for airfields.
The patent describes a frame with 4 wheels at every corner ( permitting the machine to be towed ), a generator powered by an engine and one large electrical lamp at every end of the car. 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 because of adverse weather conditions.
More lately 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 conveyable lighting tower composed of a base frame ( which has an engine and generator ) and a vertical, extending, hydraulic mast with 2 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 ensure stability in high winds.
This is kind of a big development in the history of the lighting tower as this patent principally forms the root of most modern day lighting towers which contain similar elements like a base that stores the engine and generator together with an extending hydraulic mast that supports the luminaries.
The following patent was filed later on in the same year of 1980 but was for a solution to provide more intensive illumination. The US patent 4220981 describes a framework with four 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 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 often offer illumination on only one side of the machine.
Since 1980 considerable progress has been manufactured by lighting tower makers. Although the final design has sundry small from those seen in the 1980s many improvements have been made to make lighting towers better to use and more ecologically 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 framework design which allows virtually any generator to be used to power the light heads.
The TCP Ecolite lighting tower has also broken new ground by utilising extremely cost-effective lamps to reduce fuel consumption significantly, which is very timely seeing as global warming is beginning to become a more and more plentiful concern.
