This work is on minutes emergency kitchen lighting system. Emergency light is used during the power failure to light up our kitchen especially when one is in kitchen. As it is used during the power failure, it should last long, hence generally bright white LEDs are used in emergency light, because they produce more light and consume less power. In this emergency light circuit, when the Power goes OFF, the emergency light activates automatically using LED as the lamp, and this LED stays ON for two minutes then goes OFF.
CHAPTER ONE
1.0 INTRUDUCTION
Many people keep a supply of candles and flashlights on hand for when the power goes out. But you still have to find your way around in the dark to get them. In situations like this, it might be helpful to have some kind of emergency lighting system that would automatically turn on when the power goes out.
An emergency light is a battery-backed lighting device that switches on automatically when a building experiences a power outage. Emergency lights are standard in new commercial and high occupancy residential buildings, such as college dormitories. Most building codes require that they be installed in older buildings as well.
1.1 BACKGROUND OF THE PROJECT
By the nature of the device, an emergency light is designed to come on when the power goes out. Every model, therefore, requires some sort of a battery or generator system that could provide electricity to the lights during a blackout. The earliest models were incandescent light bulbs which could dimly light an area during a blackout and perhaps provide enough light to solve the power problem or evacuate the building. It was quickly realized, however, that a more focused, brighter, and longer-lasting light was needed. The modern emergency floodlight provides a high-lumen, wide-coverage light that can illuminate an area quite well. Some lights are halogen, and provide a light source and intensity similar to that of an automobile headlight.
Early battery backup systems were huge, dwarfing the size of the lights for which they provided power. The systems normally used lead acid batteries to store a full 220-volt charge. For comparison, an automobile uses a single lead acid battery as part of the ignition system. Simple transistor or relay technology was used to switch on the lights and battery supply in the event of a power failure. The size of these units, as well as the weight and cost, made them relatively rare installations. As technology developed further, the voltage requirements for lights dropped, and subsequently the size of the batteries was reduced as well. Modern lights are only as large as the bulbs themselves - the battery fits quite well in the base of the fixture.
1.2 OBJECTIVE OF THE PROJECT
The objective of this work is construct a lighting devicethat when the Power goes OFF, the emergency light activates automatically using LED as the lamp, and this LED stays ON for two minutes then goes OFF.
1.3 SIGNIFICANCE OF THE PROJECT
- This is very simple circuit and the cost is also very less.
- power is saved because the circuit switches the LEDs based on light conditions
1.4 APPLICATIONS OF THE PROJECT
- Used in child’s study rooms to avoid the sudden power failure.
- As an emergency lamp in homes.
- Used in security systems to switch ON the lights automatically during the power failure.
1.5 SCOPE OF THE PROJECT
Emergency light is an integral part of household electronics nowadays. We all know Emergency light is used during the power failure to light up the home. As it is used during the power failure, it should last long; hence generally bright white LEDs are used in emergency light, because they produce more light and consume less power.
In this emergency light circuit, when the Power goes OFF, the emergency light activates automatically using LED as the lamp, and this LED stays ON for two minutes then goes OFF. We have used four bright white LEDs, more LEDs can be added to produce more light considering that total current consumption should not exceed the supply current. Ultra bright white LED consumes 3v and 20mA current.
1.6 LIMITATION OF THE PROJECT
In this device, when power goes OFF, the LED can only illuminate the kitchen for two minutes.
