ecosystems, solar lighting minimizes the impact on nature by avoiding below- grade services and unsightly enclosures. Solar lights can also utilize turtle friendly. PDF | In this study, we have optimized solar lighting system adapted to Algerian countryside, two representatives regions have been studied. PDF | Attempt has been made in this work to develop a low cost solar lamp with an aim to cater to the locations which are scarcely electrified and primarily in.

A solar lamp also known as solar light or solar lantern, is a lighting system composed of an LED lamp , solar panels , battery , charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar photovoltaic panel. Solar-powered household lighting can replace other light sources like candles or kerosene lamps. Solar lamps have a lower operating cost than kerosene lamps because renewable energy from the sun is free, unlike fuel. In addition, solar lamps produce no indoor air pollution unlike kerosene lamps. However, solar lamps generally have a higher initial cost, and are weather dependent.

Process: The incoming raw materials and components are tested for required quality and specifications.

The components are formed, shaped and soldered on pre-designed printed circuit boards and tested for desired performance. Connect the PV cell and check whole unit for required performance by measuring the intensity of light produced, charging current, and discharge level of battery.

Production Capacity per annum: 10, Nos Rs. The small scale entrepreneurs should have an environmental friendly attitude and adopt pollution control measures by process modification and technology substitution. A notification for detailed rules to regulate ODS phase out under the environment Protection Act, have been put in place with effect from 19th July, Alternate technologies may be used to phase out the existing polluting technologies.

Electronic industry uses CFC, Carbon Tetrachloride and Methyl Chloroform for Cleaning of printed circuit boards after assembly to remove flux residues left after soldering, and various kinds of foams for packaging. Other Chlorinated solvents such as Trichloroethylene, Perchloroethylene and Methylene Chloride have been used as effective cleaners in electronics industry for many years.

Other organic solvents such as Ketones and Alcohols are effective in removing both solder fluxes and many polar contaminants. Energy Conservation With the growing energy needs and shortage coupled with rising energy cost, a greater thrust in energy efficiency in industrial sector has been given by the Govt.

The Energy Conservation Act, has been enacted on 18th August, which provides for efficient use of energy, its conservation and capacity building of Bureau of Energy Efficiency created under the Act. Use of power factor correction capacitors. Proper selection and layout of lighting system; timely switching on-off of the lights; use of compact fluorescent lamps wherever possible, etc. The unit, may therefore, keep abreast with new technologies in order to keep them in pace with the developments for global competition, Quality today is not only confined to the product or service alone.

It also extends to the process and environment in which they are generated. The ISO defines standards for quality management system and ISO defines standards for environmental management system for acceptability at international level. Mail sates e-micrologix.

Box , , Bharat Industrial Estate T. The lower layer has less electrons and hence has a slight positive charge due to the negative charge nature of electrons.

In addition, the upper layer has more electrons and has slightly negative charge. A potential barrier is created between these two layers. When the stream of light particles called photons enter, they give up their energy to the atoms in the silicon. It promotes one electron from a covalent bond to a next energy level from upper layer to the lower layer. More light shines through, more electrons move around hence more current flows between. This process is called photovoltaic and photoelectric effect.

The encapsulate keeps out moisture and contaminants which could cause problems.

Inside the case are electrodes including cathodes and anodes where chemical reactions occur. A separator also exists between cathode and anode which stops the electrodes reacting together at the same time as allowing electrical charge to flow freely between the two.

Lastly, the collector conducts a charge from the battery to outside. This part of the lamp saves up energy from the solar panel and provides power when needed at night when there is no light energy available.

In general, the efficiency of photovoltaic energy conversion is limited for physical reasons. It ensures, under any circumstances including extreme weather conditions with large temperature difference, the battery does not overcharge or over discharge and damage the battery even further. Under the control of a DC charge controller, non-contact control automatically turns on the light at dark and switches off at daytime.
