Most people from all over the world use the name torch to mean flashlight. The real meaning of the word is a portable appliance that can deliver electrical light. To produce light the device power system must get into contact with other power materials which include diodes and bulbs among others. An industrial flashlight is made of a bulb which is put on a reflector and a cover which is transparent. There is a switch and it uses batteries. Certain types contain lenses on the front side and to magnify the light they have reflectors.
The invention is believed to have been done as early as 18th century and the power consumption for them was so high. A miniature type of bulb composition was the one used in those cases. Meanwhile, technological advances have led to the invention of new and more efficient devices as well as modifying the earlier inventions and providing them with advancements so as to make them more effective. Light-emitting diodes or LED and high-intensity dischargers HID as well as incandescent were later inventions.
Inventions have also been made such that use of solar panels has been made even on these devices allowing them to produce illumination without the help of a battery. They also have micro power saving batter which is used after the sun goes down. They help in many general functions including providing backup light when there is no electrical power.
The torches are essential and they have been used by people for various purposes. Miners, as well as mountain climbers, are some of the people using the devices. People on camping activities put the devices on their helmet to ensure they have enough light. People in the military also use them when they are in war to focus and shoot.
The first torches invented usually were driven by alloys of zinc and carbon batteries. However, these batteries did not have a consistent power supply, therefore, affecting current flow. They were eligible to rest and interval or periodic functioning. Later on, towards the end of the eighteenth century, dry cells were invented. This invention came with so many advantages. They include the illumination provided was commendable, odorless, did not produce smoke when combusting and the heat evolved was little when compared to the previous devices.
Due to these merits, their use became so much demanded bearing in mind that incandescent bulbs which consisted of similar characteristics were invented at the same time. The bulbs comprised of the internal filament made with materials like tungsten, a vacuum filled with inert gases like argon, xenon, and krypton then covered with a glass. These gases prevented the filament from burning due to their inert nature to combustion. Halogen lamps were also used where this was the gas used to fill the vacuum alongside others like bromine and iodine. However, the life of the bulb was not guaranteed.
In early twentieth century, another evolution of these devices occurred. It came with devices that are able to emit white color light through diodes instead of filaments. They are referred to as light-emitting diodes which are commonly abbreviated as LED. They have penetrated in almost every corner of the world and are taking part of incandescent bulbs.
These benefits include low power consumption of up to 1 watt. Large light beams produced, durability and damage resistance, no heat evolution, different color production among others.
