"LED LIGHT PROJECT IN PAKISTAN"
Dec 24 - 30, 2012
LED stands for Light Emitting Diode, and a diode is a special semiconductor that conducts electricity in just one direction. The diode is made up of layers of silicon that has rare earth elements such as phosphorus, germanium, or arsenic in between the layers. The layers are called the die and the space between these is where the light is generated. Different materials and different designs in the diodes create light of differing colours and intensities.
Traditionally, LED lights weren't suitable for everyday lighting as they could only produce white light by grouping together red, blue, and green LEDs to produce a light that looked white. However, modern LEDs can come in warm or cool whites just like standard bulbs as well as in a range of colours such as red, blue, green, purple, yellow, orange, aqua, and so on.
Dramatic improvements in technology mean that LED lights can be used for a whole range of applications. LED lights are also more resistant to damage than other types of bulbs and they will not flicker. LED lights can be used for:
* Strip lighting
* Ceiling lighting
* Outdoor lighting
* Pool lighting
* Night lighting
* Pool lighting
* Fairy lights (or festive lights)
LED lights are becoming more and more popular because of their incredible energy efficiency. They use much less power than other types of lights in order to produce a bright glow. As well, LED lights can be expected to last for around 100,000 hours or more which is much longer than standard incandescent bulbs which have a lifespan of 1000 hours or fluorescent bulbs which have a lifespan of about 8000 hours. Essentially, once you install an LED light, you should not have to change it for years, if ever as each bulb should last for around 30 to 40 years of normal use.
In Pakistan LED lights are recently introduced by KESC, an organization providing electricty was incorporated in 1913 via the Indian Companies Act of 1882. In 1952, the Government of Pakistan(GoP) acquired a majority shareholding of KESC. KESC is the only remaining vertically integrated power utility in Pakistan and has exclusive franchise rights to serve Karachi, Pakistan's largest city, and its surrounding areas. The Company has about 11,600employees; its network spans an area of 6,000 square kilometers and serves roughly 2 million customers. Listed on all three of Pakistan's stock exchanges, KESC has a market capitalization of nearly US$ 725 million and generated revenues of nearly US$ 1 billion in fiscal year 2008.
Apart from all the criticizm KESC (Karachi Electric Supply Corporation) usually face because of the never ending loadshedding issues, this governement organization is trying their best to play a positive role in the development of Pakistan with its limited resources, uncertain political and economical issues and heavy criticizm. The recent example of KESC's effort for the betterment of the country is LED light project. KESC has successfully converted the interior conventional lights of Quaid-e-Azam Mohammad Ali Jinnah's mausoleum to the latest LED based lighting technology. KESC's CEO, Tabish Gauhar inaugurated the LED lights here at the mausoleum on Thursday. The KESC has replaced 256 old/conventional lights inside the tomb and museum with the latest, green-technology based LED lamps. The lighting effect after this transition to the LED's has magnified the grandeur of the national heritage by complimenting the beauty of the mausoleum and bringing out its previously understated effect. In the first phase, the conventional lamps of the mazar's ground floor chandelier, basement chandelier and the museum illumination were converted to the LEDs.
The 8.32kW power consumption load of the conventional lighting, has now commendably been reduced to 1.78 kW only, achieving a substantial saving of 79 percent. The financial impact of the savings from the reduction in power consumption will be more than Rs 0.4m per annum in terms lower energy bills. More importantly to note is the fact that LED technology based lights have a far greater useful life, emit no radiation, and are based on the green energy concept with zero carbon foot print, curbing the adverse affects of global warming while preserving our environment.
Furthermore in the second phase which is in progress with KESC's technical support and the partnership Quaid-e-Azam Mazar's Management Board, the entire exterior lighting scheme of the mausoleum will be transformed into energy efficient LED new technology. KESC is actively participating in environmental and energy conversation programs in order to create awareness among the consumers. The industrialists are all pout to adopt the latest and environment friendly conversation methods and are keen to adopt new technologies including LED lights in order to make their units viable considering the energy crisis and skyrocketing prices of energy. Energy crisis and ever increasing prices have almost rendered the industry unviable and the exporters are unable to compete in the international markets due to exorbitant cost of gas, electricity .
Its high time for not only the industrialist but also the home based consumers of KESC fto adopt and procure new technologies of energy conservation. If the industrialists adopt energy conservation plans as suggested by KESC they could well save Rs200 million annually which are being wasted due to non-awareness. Recently KESC has signed MOU with the local builders and developers for adopting new methods of energy conservation in their upcoming projects. KESC is working on energy conservation plans for the last three years.
In future KESC is planning to replace LED lights in shopping malls, hotels, historic places, institutes and other public places where the consumption of electricity is extremely high. KESC is also creating awareness in the consumers to use LED lights in their homes by visiting different schools, colleges, universities and shopping malls. As compare to solar energy, the LED lights are more easy to install and convinient for the users. LED light project can play a very significant role in the betterment of Pakistan's economy, by using it lot of energy can be saved.
