Nokero company, for example, proposes to noncommercial organizations the light-emitting diode lamp n100 with the built-in solar cells and nickelmetalhydride battery. In sunny weather the lamp can for a period of the light day to accumulate a sufficient charge in order to work as a minimum for two hours.
Lamp contains five light-emitting diodes and four solar panels. Battery is calculated for two years of service, luminous source as a whole is capable to serve not less five- ten years. From the start in the daytime, the built-in sensor of illumination protects lamp. Producer proposes lamp for $15. Similar lamps are not new, since on the market for a long time are present green garden lamps, which are loaded from the solar batteries.
Note the effectiveness of solar battery work is substantially reduced due to the pollution. The duration of the light day and the intensity of sunlight also substantially influence the ability of battery to accumulate energy for the work at night. Finally, even the theoretical two- four hours of work on the net charge of proper battery for many users can be insufficient. Related Products :
