Benefits of LED Lights Vs CFL Essay

plot of ground the most walking spaces dis socio-economic class regarding nix capability revolves n other(a) extremely visible feature like solar panel, another(prenominal) efficiency technologies sport the potential to reduce the amount of aught consumption signifi rattly in walking space. With organizations such as Saudi Aramco where employees walk, jog, the ride cps and other different activities, the expenditure of zippo conservation squeeze out swallow important environmental and monetary impacts. This report aims to declare oneself Saudi Aramcos maturate utilizeful information about new technologies for energy and appeal bringing by qualification improvements to their play course. This report offers a starting even for considering energy efficiency improvements in the organizations environment.It has been exterioriseed that galvanising energy for touchwood consumes around 20% of the worlds male monarch directs production. Introducing energy busines slike unobjection up to(p)ing to all our informaling of necessity will dramatically reduce the overall consumption of worldwide energy. all small changes in our lighting apply will produce inviolable energy savings in the end. The high-energy use can be addressed by using cleaner energy sources, such as solar panels, and by using light sources that require less energy and produce the same levels of lighting. This report will propose an efficient lighting project to reduce the energy consumption of the lights employ to illuminate the paseo around the Dhahran Golf Course.BackgroundThe Walkway around the Dhahran Golf course is most 5.6 kilometers long. The walkway is employ daily by Saudi Aramco employees to walk, jog, bike and other different activities. Most of this walkways use happens at night, after working hours, meaning that it needs to be well lighten for the employees use. Currently, Compact Fluorescent (CFL) light electric-light bulbs that are fixed to poles all ar ound the walkway illuminate the sidewalk. CFL light bulbs are considered to be more than efficient than traditional Incandescent Light bulbs, having a go life history of approximately 8000 hours com equatinged to a maximum 1,000 hoursfor Incandescent light bulbs. This longer service life results in fewer light bulb replacements, but more efficient technologies exist.For the Dhahran Golf Course walkway efficient lighting project, the police squad proposed the use of three innovative energy reducing technologies. The three techniques are, Light Emitting Diodes ( lead), solar panels to power the LEDs, and a special natural that uses energy poised during the day to glow in mordant. A brief summary of separately applied science will be given to better understand its use can contribute to providing more efficient lighting for the walkway.Light Emitting Diodes (LED)LED light bulbs emit light through the use of a semiconductor unit that releases light energy when an electric curren t is passed through it.This way of producing light differs from CFL light bulbs, which pass energy through mercury vapor to stimulate UV light, which is then enthralled by aphosphor covering at bottom the lamp, causing it to glow. LED light bulbs have been in existence for around time now but were very expensive compared to Incandescent and CFL light bulbs. Over the last couple of years LED light bulb prices have dropped significantly, making them a more economically viable resoluteness, oddly when considering their very long service times. The table below details the differences betwixt CFL and LED light bulbs.Light Emitting Diodes (LEDs) Compact Fluorescents (CFLs)Life Span (average) 50,000 hours 8,000 hoursWatts of electrical energy used 6 8 watts 13-15 watts(Equivalent to 60 watt bulb).

May catch fervourAs depicted from the above table using LEDs for lighting assimilate both economic and environmental sense.Solar panelsSolar panels are used to produce energy by converting fair weather directly into electricity. The electricity generated by solar panels is stored in batteries for later use. Just like LEDs, the costs of solar panels the past several years have been dropping, making them more economical. They have similarly become more efficient in converting a high percentage of the light captured into electricity.Glow in the Dark Paint/StonesCo nsists of a luminescent material and synthetic resins that get excited by cosmos exposed to daylight or a light source broad it an afterglow that initially is very radiant, then slowly dissipates as time passes by. This material bids a soft glowing light that only needs the sunlight during the day for it to produce light at night. This material can provide 10 hours of burning when exposed to only 2 hours of daily sunshine with a Luminescence Life of up to 20 years.Methodology send-off the team obtained data set from the Saudi Aramco accounting department which contained a listing of cost energy spent. The data set also provided estimated energy use in lighting in Saudi Aramco. From here, the team was able to filter the data only for lighting around the Dhahran Golf course. With this data set, the group generated summary statistic to find distribution for energy consumption (mmBTUs). The endeavor of defining statistical use was to estimate energy consumption for the Golf course as well as understanding the range of the golf course.Next, the team then evaluated different technologies to gain energy saving potential. An early obstacle the team faced was how to estimate the impact of each engineering on various places in the Golf course. To find a solution for this issue, the team conducted case studies and independent research to evaluate the other technologies. The team performed a systematic analysis of each of the techniques named above. Each applied science was eluted base on cost estimate for the project, difficulty of installation, a percentage pass judgment efficiency gains, estimated payback periods and consistency of paybacks.ResultsThe figure that follows represents the consumption of energy (from 2013). newsA case study analysis of the literatures suggested that the combination of all the technologies had a greater benefit-cost ratio than one and net present values thereof indicating the benefits of energy saving brought by the technique. To prevent the high rise of energy consumption as suggested by the figure above, ultrasonic and infrared technology would be of greater benefit. These methods detect sound, heat, and motion, hence more efficient in spaces where people move more efficient. A more inventive technology such as this would increase the energy saving potential, but also may be unattractive to administration who have less manage as to when the lights turn off in particular spaces. Despite their advantages, they stop overmuch more costly to purchase than alternative lighting types. devotionThis proposed design was first constructed by Daan Roosegaarde, a scene night painter, who real a bycle path in Nueener, East of Eindhoven forming a part of the train gogh cycle through Noord-Brabant in Netherlands. According to Roosegaarde, this proposed technology is more gentle to the eye and surrounding environment compared to other existing technologies (De zeen magazine, 2014, par 4).Recommendation and plan of act ionThe solution I am proposing is a combination of the three technologies explained, LED lighting, Solar panels, and glow in the dark materials. First all the CFL lighting should be removed. CFL bulbs have a much shorter service life and have higher energy requirements. Due to the long and very low energy use, LED lights will be used instead. The LED lights will be powered by the proposed solar panels, making the solution self-reliant with no need to connect to the electrical power grid. In addition to the LED lights, the glowing material/paint that is rigid on the walkway itself, will utilize the sunlight during the day to provide a glowing light at nighttime. With this combined solution, we will pull in the following benefitsLower energy cost (no need to connect to the electrical grid)Environmentally friendly solutionSelf-reliant, all power is from the sunlight press out the need for CFL that contain hazardous mercuryLower maintenance costLess frequent bulb replacement, due to LED long service life and durability.Energy efficiency avails an incredible opportunity for positive local, guinea pig and international impact. While organizations save money, the organization strain on the electrical system is relaxed, hence lowering of the global pollutant emission. Whatever the motivation, energy efficiency should be viewed as an opportunity to upgrade organizations. Saudi Aramco is encouraged to use this report as a supplemental resource in their decision process. After reading through the report, Saudi Aramco is heartening to learn supercharge details about energy efficiency technologies of their interest.ReferenceBenefits of LED Lights Vs CFLs retrieved from http//lifx.co/lighting101/advantages/led-vs-cfl/ comparing Chart LED Lights vs. Incandescent Light Bulbs vs. CFLs.
