A few years ago, I was watching a documentary on the Discovery Channel, which I couldn’t remember the name of the documentary at the moment, but the subject and the assessment astonished me. The theme was about a few people who were trying to provide light to an aphotic village where is located in the foothills of a mountain in China. Plus, the assessment was to provide light to that dark village. The transportation to the town was robust since the town was located in the foothills of a mountain, but a group of people voluntarily managed to reach to the village single-mindedly and achieved to provide light to them. While they provide light to that village admirably, the tools they have used are a few volunteers, batteries, solar panels, a few donkeys for the transportation and light-emitting diodes (LED).
LEDs have a “standard” size of 5 mm in diameter. It has a shape of the round-cross section. Another type of light-emitting diode is the smaller sized ones that have a scale of 3 mm in diameter, and its form is again the round cross-section. The standard-sized LED is the most popular one that has been used, but 3 mm diameter sized LEDs are also becoming popular. The LED light bulbs can be found in different colors from green to purple and from warm white to soft white.
There are a few reasons and advantages of why the volunteers of the project decide to use light-emitting diodes. Firstly, LED light bulbs are long-lasted objects. It can enlighten for many years without any wear and tear. Secondly, LED light bulbs are durable, which makes them hardly broken. Thirdly, since they are long last and permanent, in the long-term they are less expensive; hence, it is a pocked friendly light bulb. Fourthly, it is portable and practical in use. It can be relocated quickly and switched rapidly. Lastly, it is less power consuming. The LED light bulbs include lower infrared and ultraviolet outputs which make the LED light bulbs more environmentally friendly. Moreover, LED light bulbs do not bring out carbon dioxide emissions and do not contain any toxic material. The only adverse effect of the LED light bulb is its expensiveness of initial purchase in the short run, but its price has been fallen year by year as it can be seen in the graph.
To conclude, after finishing watching the documentary, I went into a muse. Thinking about a brighter and cleaner future, without any person living in dark cities or villages; enlightening the life, the hope and the dream of everyone and everywhere with LED light bulbs. Thanks to the volunteers who provide electricity and light to that village; the peasant can survive much more quickly and take a step forward towards the modern age and more importantly, the children can read and get the education they need. Seeing the warm smile of those people in their eyes was a very privileged bliss for them, and I think this is the main reason why the volunteers decide to actualize this project.
