I. Introduction
The objective of an electricity supply utility is to provide a wide range and variety of customers with a supply of electrical energy. Their main aims are to meet the variable and instantaneous demand for electricity at the most economic cost, and to achieve customer satisfaction by a good standard of reliability and quality in terms of voltage and frequency. However reliability and continuity of supply from the electricity supply. Utilities cannot be guaranteed absolutely as power outages and disturbances must be expected at some time.
The solar photovoltaic (PV) street lighting system comprises of a Compact LED lights as light source, re-chargeable lead acid battery for storage, PV modules for charging the battery, suitable electronics for the operation of the tamp and safe charging and discharging of the battery and mechanical hardware for fixing these sub systems.
Luminaires are also available with Low Pressure Sodium Vapour (SOX) lamps and higher wattages of compact flourescent lamps against specific customer requirements. The SOX lamp is a monochromatic (Yellow – Orange) light source delivering the highest possible lumens per watt. CF Lamps provide slightly less lumens per watt, but produce a white light which actually appears brighter than SOX and should be used in areas where colour rendition is critical.
I. Objective
The main objective of this project development is ;
1. To study and compare between LED and others power lamp.
2. To develop the portable solar street lamp with the sun light
as the source.
3. To find information about type of LED and power lamp and
also benefit of each lamp depend on environment.
also benefit of each lamp depend on environment.
I. Problem Statement
The project is based on replacing existing high pressure sodium (HPS) street lamps with a more efficient lighting system and also can minimized the cost. The two systems compared are LED and power lamp street lighting. The lighting selection is also vary according to size of input and output depend on type of lamp. Cost of first installment is very high and required substantial capital. The efficiencies of the street lamp were compared as well as the carbon footprint from the lamps life cycle. Costs include upfront price, maintenance costs, lifetime of the bulbs, efficiency in use and carbon footprint from production, distribution and in use. This spread sheet provides a base cost and analysis of efficient lighting systems for city street lights.
I. Methodology
Block Diagram of Solar Panel for Street Lighting
This block diagram above is about the combination of the charging circuit and circuit controller to the load and the DC voltage source. At the day, solar panel will get the energy from the sun and the circuit charging will control the charging rate to the battery. The charging circuit will control the charging until the battery reaches the floating condition that is the full condition of the battery. The charging only occur when in the day because the solar need for the light to transfer the sunray to the electricity. When in the night condition circuit charging automatically stop charging and diode 20L15T are use to eliminate from current draw from the battery to the solar panel when in night condition.
