E light solar LED based lamp

E-Light is a solar rechargeable LED based eco friendly lamp used for indoor and outdoor applications.

Lighting is taken for granted in industrial countries and in many urban areas of developing countries. It is hard for many people to imagine living at night without being able to obtain light at the flick of a switch.

However, about half of humanity (from China to Latin America, from India to Africa) lives without light after the sunset, since they do not have access to grid-connected electricity. The unavailability of electricity and, consequently, lighting in such rural areas affects not only the lifestyle of the inhabitants but also the economy, the culture, and the safety: Without lighting, the majority of working activities must be suspended, and productivity is significantly penalized [Ref 1]. Reading, studying, and interacting with other people become activities more difficult to realize when the sunlight is no longer available. The darkness of the streets impacts safety in different ways (road accidents, crime). Among the various possibilities to fulfill this need, solar LED lighting solutions are gaining more and more consideration. These solutions combine the use of an ecological and renewable energy source with an efficient way to convert energy into light. Solar LED solutions Lighting in rural areas of developing countries is generally provided by wax candles or combustion lamps (e.g. kerosene), while flashlights powered by batteries are used as portable sources of light for intermittent use. These sources are cheaper than any form of electricity. On the other hand, the low efficiency, the poor quality of the light and the intrinsic fire risk of all combustion light sources suggest the use of electric lighting in off-grid locations. The unavailability of the power grid implies that the electrical energy must be produced locally. Among the methods by which energy can be produced, photovoltaic systems (solar cells) are by far the most universally applicable. The general principle is to convert the sunlight, in particular energy carried by photons, into electrical energy. The use of photovoltaic systems brings some advantages: solar energy can be produced locally; hence the solar panels can be installed everywhere (also in areas of difficult access) without the need for infrastructure. This also minimizes the transmission/distribution losses. solar energy is a renewable source; it does not impact the environment with pollution. the facilities can operate with little maintenance or intervention after initial setup; this contributes to reduce the energy cost. photovoltaic systems generate low voltages; this simplifies the downstream conversion of power. However, energy production by photovoltaic systems must take into account the intrinsic periodicity of the solar source (e.g. during the night the energy source is absent). Storing the electricity in batteries would ensure a continuous availability of energy. Once the electrical energy has been produced and stored, the next step is generating light in a wise way, in terms of energy saving and in respect to the environment. The use of white LEDs is becoming of primary importance in this direction for the following reasons: High luminous efficiency (more than 100 lumen/watt), which implies less wasted power in comparison with other light sources (for example, incandescent bulbs) Hazardous materials free (mercury or toxic gases) - LEDs provide the cleanest light in ecological terms Low driving voltages, making LEDs particularly suitable for photovoltaic systems. In the last few years, significant steps forward in LED technology have been achieved, especially in terms of power capability. The availability of LEDs up to 5 W, combined with their high luminous efficiency, contributes to their diffusion in the lighting market as replacements of traditional, and often less efficient, light sources.
