The History of Invention of Cartable Lighting Tower
Who invented the 1st cartable 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 a large area, such a device has doubtless been in use since the Stone Age.
In more up to date 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 airports.
The patent describes a chassis with 4 wheels at every corner ( permitting the machine to be towed ), a generator powered by an engine and one giant electrical lamp at every 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 due to inclement weather conditions.
More lately in 1980 a US patent 4181929 was filed for a Portable illuminating tower that illustrates a much closer similarity to current day lighting towers.
The US patent 4181929 describes a cartable lighting tower composed of a base frame ( which has 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 easily 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 serious development in the history of the lighting tower as this patent mostly forms the root of most current 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 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 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 allows for the masts to be revolved enabling finer control of the area of illumination. By offering 2 masts the light tower also allows for illumination over nearly all sides of the machine. This is not like prior light towers which generally offer illumination on only one side of the machine.
Since 1980 substantial progress has been made by lighting tower manufacturers. Though the final design has sundry tiny from those seen in the 1980s many enhancements have been made to make lighting towers better 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 framework design which permits virtually any generator to be used to power the light heads.
The TCP Ecolite lighting tower has also damaged new ground by exploiting intensely cost-effective lamps to reduce fuel consumption seriously, which is particularly timely seeing as global warming is becoming a more and more common concern.
