The Design And Construction Of A Solar Street Light (PDF/DOC)
This project work is titled design and construction a solar Street Light system. Stand-Alone PV street light System supply an alternative means of electrification. A street lighting is any electrical lighting that is fixed in the road for the illumination of such road or a Street light is a raised source of light on the edge of a road or walkway, which is turned on or lit at a certain time every night using solar energy (solar panel) as the primary power supply.
In this device, the solar energy is tapped and converted directly in to electricity by the solar panel (photovoltaic cell) which is being used to power a solar street light. The battery stores the excess solar energy during the day which the charge controller prevents the battery from overcharging and also charges the battery. This project unveils the design and construction of a solar energy street light system with dust to dawn operation with the aid of tight dependent resistor (LDR). The basic system components include a 50watt solar panel, 100Ah solar battery, 12 volt charge controller, 15watt energy saving bulb 3.5meter pole and interconnecting cables.
5.1 CONCLUSION
Street lighting is any electrical lighting that is fixed in the road for the illumination of such road or is an electrical device used to create artificial light by use of an electric lamp that is used in the road. All street light fixtures have a fixture body and a light socket to hold the lamp and allow for its replacement.
Street lighting can illuminate your road; it can help you to see who is calling at night and deter criminals from lurking; it can allow you to make the most of a patio during warm summer nights; and it can create dramatic visual effects of light and shadow among the plants.
Major advantages of street lighting includes: prevention of accidents and increase in safety. Studies have shown that darkness results in a large number of crashes and fatalities, especially those involving pedestrians; pedestrian fatalities are 3 to 6.75 times more likely in the dark than in daylight. External lighting has been found to reduce pedestrian crashes by approximately 50%.
5.2 RECOMMENDATION
This project is designed to be used in our road where the need for illumination is needed. And should be used and maintain by a qualified personnel.
Working on this topic as my project is a good idea and it comes at the right time. I am suggesting that this particular topic should also be given to other students both in higher and lower class.
