A Homemade Solar Lantern in Developing Countries

Today, in the world more than 1.5 million people in Africa, Nairobi, Asia and Latin America live without the benefits of electricity. When the sun sets, however, his day is far from over: when the daily work in the fields is done, family and social take care of life, goods are sold in night markets and kiosks and community centers become meeting points for people the locals. Not until late at night do housewives find the opportunity sew or do housework and many students only get to work after dark. Because of this less electricity use people mostly buy cheap solar lantern in Nairobi.

Lighting for these colorful scenes comes in many forms. The rich are able to afford diesel generators, while the poorest must comply with candles and glow the fire. However, the most common source of artificial light in countries like Kenya, Peru and Afghanistan is the kerosene lamp - ranging from simple wick lamps low-cost pressure lamps with high-quality gas lamps They are popular among campers in Europe. The luminous efficacy many traditional lighting methods is very low and poor value for money: oil lamps and candles cost a typical household in developing countries 40 to 80 US dollars per year (actual costs vary widely in international fuel prices, national taxes, and households’ behavior).

An Alternative: Solar-powered Lanterns

In an effort to curb this waste of resources, development organizations have been spreading alternative lighting technologies two decades, including solar powered solutions. In these devices, solar cells convert sunlight into electricity during the day charging a battery, which in turn produces light for use at night. The more common light source used in this type of solar systems is the compact fluorescent lamp (CFL), although the recently more efficient light emitting diodes (LED) have become more extended.
Solar lamp developed by LED safari implementation is a more efficient, safer and less expensive lighting traditional oil lamp currently used by more than one billion people in the world. An integral part of this young start-up of Lausanne is a three-day educational workshop organized locally and led by trained commissioning to educate and train beneficiaries’ globetrotters.

To Overcome Problems

In order to overcome the use of many problems caused by a solar lantern 1.6 billion people around the world, LED safari developed an ingenious system, from the existing site, such as wires, a mobile phone battery and an empty bottle equipment to do their own light. More than 200 people in India, Kenya, and Tanzania who attended the workshop have begun to accept the economic and health benefits of this ingenious system and through this process are enjoying the daylight.

Development of new sources of third world countries faces reappearing problems: cost and long-term integration into everyday life. Ph.D. in solar energy and building physics laboratory has a distinct idea of developing this basic, but the effective lamp. A design was presented to anyone, these lamps require more than what is found on the local device. Therefore people buy cheap solar lantern in Nairobi.Solar panels are come from abroad. Five to six hours of charging in the sun enough for four to five hours of light.
