This project work is on design and construction of a smart emergency light system. An automatic emergency light is an electronics device used in turning light ON during dark condition. Smart Emergency Light will turn on the Emergency light only during the Dark condition. Ordinary emergency light will be switched ON during the power failure condition. So that if there was a power failure in day time the ordinary emergency light will als […]
Automatic security lighting system is any electrical security lighting that is fixed outside house for the illumination of such environment or a 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. Automatic security light controller will automatically turn on security light in the way of LEDs or bulb coupled with relay. This system employed the output from an unc […]
This low cost automatic emergency lighting circuit turns on a lamp during power failures. It is powered by a NiCad battery that is being charged by the main power line when there is no blackout. The circuit design is very simple and can be made by almost anyone. The voltage from the step down transformer is rectified by diode D1 and filtered by C1. The NiCad battery gets charged with about 100 mA via the diode D2 and resistor R1. The b […]
This project work is titled design and construction a solar security Light Control system. Security lighting is any electrical lighting that is fixed in the house or road for the illumination of such road. It turns on or lit at a certain time every night using solar energy (solar panel) as the primary power supply and the LDR as the controller. An Automatic Street Light Control System is a simple and powerful concept, which uses trans […]
ABSTRACT This work is on solar powered pedestal lighting system. This solar powered pedestal lighting system uses power LEDs for lighting. Solar energy is first converted into DC electricity by a solar photovoltaic cell and used to charge a storage battery. The solar energy stored in the battery is utilised at night for pedestal lighting using power LEDs. Connection of power LEDs on the pedestal is through a control unit that has a l […]
ABSTRACT Generally, street or home lights are switched ON for whole night and during the day, they are switched off. But during the night time, street lights are not necessary if there is no traffic. Saving of this energy is very important factor these days as energy resources are getting reduced day by day. Alternatives for natural resources are very less and our next generations may face lot of problems because of lack of these natu […]
