Phosphors and Its Importance in Lightning Industry

Phosphor are inorganic compounds which shows the luminous properties. A phosphor is a material that demonstrates the luminescence phenomena; when subjected to some sort of radiant energy, it generates light. The word is used to describe materials that glow when exposed to ultraviolet or visible light as well as materials that glow when impacted by an electron beam. When a phosphor material is subjected to irradiation, the orbiting electrons within the molecules are stimulated to an excited state; when they return back to their original state, the energy is emitted as a specific hue of light. Phosphors are classified into two types: fluorescence substances that emit energy instantly and cease glowing as soon as the irradiation is turned off, and phosphorescence substances that emit light after a delay and continue to glow even after the light is turned off, and continue to glow from milliseconds to days.



Primitive, traditional, and modern agricultural stages are just a few of the major phases that have characterized the development of agriculture. One of the key protagonists of ancient agriculture is doing some modest work with stoneware. Humans developed ironware and began employing tools made of iron and wood during the conventional agricultural phase, which significantly increased output. The agricultural economy advanced greatly during the modern agricultural stage, which saw the deployment of sophisticated agricultural machinery.

Agriculture in modern times encompasses more than just growing crops and raising cattle. Agriculture faces obstacles because of the environment, so all agricultural action  should be modern and scientific in nature. Farmers must lessen their environmental impact due to climate change, and this is where modern technology may help.

These are some examples of how computers are used in agriculture. Software that aids in predicting weather and calculating agricultural output Information on production, transportation, agricultural procedures, and costs involved in predicting and calculating profit and loss are all kept on computers.

The internet is increasingly used as a means of communication between farmers and agricultural specialists, facilitating knowledge exchange and serving as a resource for farmers looking to increase production and profit.

The practice of farming in those fields that take less work and produce more has evolved because to the application of software technologies

Mechanization has boosted production speed and quality while reducing labour requirements for humans and animals.

Farm Land Evaluation

In order to support what is now known as precision agriculture, ranking systems that carry out role assessments and give site assessments are being developed using geographic information systems (GIS). These interactive, high-tech devices offer information depending on a range of variables, including soil characteristics, drainage and slope issues, soil pH, nutrient status, etc..

Phosphor layers has many applications in lightning industries, it produce the majority of the light emitted by fluorescent lights and are also employed to enhance the balance of light emitted by halogen lamps. Phosphor layers are used in neon signs to create multiple hues of light. Electroluminescent displays, such as those seen in aero plane instrument panels, employ a phosphor layer to provide glare-free lighting or as mathematical and graphics display technologies. White LED lights are made up of a blue or ultra-violet emitter where a layer of phosphor coating is done that glows at specific wavelengths, providing a complete spectrum of visible light.

Kalinga Plus is an initiative by Kalinga University, Raipur. The main objective of this to disseminate knowledge and guide students & working professionals.
This platform will guide pre – post university level students.
Pre University Level – IX –XII grade students when they decide streams and choose their career
Post University level – when A student joins corporate & needs to handle the workplace challenges effectively.
We are hopeful that you will find lot of knowledgeable & interesting information here.
Happy surfing!!
