1. solar powered led street light with auto intensity control led based street lights owing to their high efficiency and ease of intensity control are now frequently
the large quantity of electricity of many countries is consumed in lighting the streets. most of basic street lighting systems are switched on/off at regular intervals of time. in this thesis, the system is to develop a street light energy saving control system to reduce energy if
system design, solar energy materials, supplementary energy storage and conversion devices. an establishment of solar energy research enclave will catalyze the accomplishing of this goal of national importance, and this is the genesis of this proposal for solar energy research enclave (sere). 2.1. objective of project (1
since they re grid connectable, the lights can send excess power from the wind turbines and solar panels back through the grid. the constantly moving turbine technology in the lights should last twenty years, requiring just an annual maintenance check up, barring natural disasters or accidents.
intensity of light, while the other voltage will be weaker b. solar tracker one solution to the aforementioned constraints is to integrate a solar tracker circuit into the design, which will allow constant alignment towards the sun and can potentially increase the production of
light emitting diodes (leds) have recently entered the lighting market as an energy efficient alternative to traditional light sources such as incandescent and fluorescent bulbs. these lights still have an enormous amount of room for technological growth and offer various advantages over all

executive summary. documentation of the energy yield of a large photovoltaic (pv) system over a substantial period can be useful to measure a performance guarantee, as an assessment of the health of the system, for verification of a performance model to then be
the project aims at saving energy by detecting the vehicle movement on highways and switching on the block of street light ahead of it and simultaneously switching off the trailing lights. the project requires sensors to detect the vehicle movements and switches on the lights ahead of it.
increasing the vegetative landscape cover and enhancing the solar reflectivity of paved and roofed surfaces within an urban area. it is proposed that in addition to a decrease in temperature, the modification of an urban surface to include more vegetative cover and lighter, lower albedo
the provision of street lighting requires an electricity supply and is associated with ongoing power costs. solar panels may be considered as an alternative power supply. adequate clearance must be provided to overhead lines. low pressure sodium lamps may be used to reduce light pollution particularly in
