Development of Energy Efficient Lighting Technology
LED VS TUNGSTEN
Abstract
Since many government regulations are clamping down on wastage of energy. Incandescent lighting technology and many Lighting producing companies focusing on developing more energy efficient lighting technology. Therefore, it is important to discuss the emergence and growing popularity of the lighting.

Introduction
1.1 Background
LED is used for light fixtures which were created in 1962 to produce light using a light emitting diode (LED). Since then the technology has grown rapidly, with LED lights becoming an extremely popular lighting solution in recent years amongst many Studio lighting producing companies. LEDs have become the most efficient source of lighting available, using up to 90% less energy than incandescent lighting and 60% less than fluorescent lighting (Bevan, 2017). The process of generating light is what distinguishes LEDs from traditional lighting, as regular incandescent bulbs produce light by creating heat.

Light Emitting Diodes is an electrical light source that only allows an electrical current to flow in one direction. LEDs contain two conductive materials that are placed in contact with each other. Once electricity is applied to the diode, the atoms in one material become charged with energy. This energy is then released in the form of electrons into the other conductive material – this release of energy is what creates light (Bevan, 2017). It is basically a semiconductor that can convert electricity to light.
Tungsten lighting refers to the common incandescent light bulb. Incandescent light is an electric light that is heated to such a temperature that it glows to provide artificial light to indoor areas. The filament used in tungsten is metal, with a very high melting point and capability to glow when heated (McGill, 2015). This method of producing artificial lighting is highly inefficient as they can only convert 5-10% of the energy they produced into the light, while the remaining energy is converted to heat. This results in an extreme waste of electricity (Beaconlighting.com.au, 2019). Whereas, most attractive benefits of LED lighting over traditional lighting technology has been its super efficiency when compared to other light sources.
In order to prepare great art, it is necessary to control and manipulate light correctly to get the best luminosity, texture, colour and vibrancy. Advanced technology and innovative gadgets had overall changed dynamics of the media industry. It now demands a professional production and for that lighting carries great weight in terms of settings and toning up mood (PAUL, 2016). However, most of the productions are still using traditional light kits but since last decade LED’s are becoming convenient and a conservative option.
The following project will tend to look into the technology behind Led lighting and Tungsten Lighting. Various comparisons would be made ranging from their efficiency, cost effectiveness, environmental friendliness, availability, life span and specifically their uses in the studio when it comes to cinematography. The advantages and disadvantages of both technologies would be discussed as well. Moreover, an in-depth study of lighting kits available at the university would be done. Furthermore, we would be evaluating LED lighting and Tungsten fixtures in terms of their output power and colour accuracy.
3.1 Project Aim
According to online records, Spaghetti studio – a popular hire studio, have over 25 lighting kits ranging from LED Top light to Fluorescent Flolight to 3x Fresnel Dedolight. This lightning comes in different power ranges powered by different lighting technology giving one different option to choose from.
This project aims to:
3.2 Project objectives
The following research is expected to act as a catalyst for a better change in the university lighting and improved content creation. At the end of this project the following objectives would have been achieved:
Evaluating LED light availability in University
Monitoring output power and colour accuracy
Critically evaluating benefits of LED over Tungsten.
Comparing results of all different tests
Evaluating and concluding new lights requirements
Proposal on best Lighting kits to University for future purchase based on findings
As it is often said – ‘Change is constant’, there is a need for constant re-evaluation of kits accessible at the university. Technology is fast evolving based on unending demands for more energy efficient, environmentally friendly, safer and easy to use lighting source, more lighting producing companies such as ARRI and ROTO light are focusing on LED lighting technology, as it is observed in their recent products.
It is important that the university too gradually starts embracing the LED lighting technology as it has been predicted by many productions of Tungsten lighting will reduce over the years with more focus and research on the earlier mentioned technology (Beaconlighting.com.au, 2019).
There is also an increasing advantage of LED over Tungsten lighting in the cinematography world as its technological advances. This is highlighted by the major lighting renovation done by KNPB-TV a broadcast studio as they transitioned to LED lighting, replacing all the Incandescent fixtures (Leeper, 2018)

The role of a methodology in research is the process which is used to collect data, process it into meaningful information that is basically used to support the aim of the thesis. The methods for gathering this data will be in a systematic form so as to guarantee that the correct statistical data is gathered. This following research project methodology constitutes a systematic literature review. The key purpose to conduct the research is to synthesize the result of colour, texture, luminosity, and vibrancy with the advanced LED lighting compared to Tungsten lighting.
The data for all following test is to be collected from university premises using data collection tools. Moreover, the project follows 4 phase process in order to complete with the research methodology
Risk assessment has now become a very important part of the project management, the key purpose is to remove uncertainty, prevent accidents and control the overall project cost while executing, controlling and implementing the project (MAJEED, 2018). Although there are no set rules for risk assessment and control procedures usually researchers take some general steps to identify risk and practicable control measures to ensure project success and purpose.
There is no risk attached to this project, as findings would be acquired from the online sources and visiting the site. However, while conducting the research and executing the project following risk can be deduced;

Ethics is simply knowing the difference between the right and wrong where every right step builds blocks for a better society. The one who isn’t aligned with ethics is a wild beast who is lost in this world. There are no major ethical implications surrounded by the following research. Comparatively, the following research plan strives for a better environment by saving energy for a better future.
