Light , Lighting and Energy Efficient Lighting

• Light - The natural or artificial agent that stimulates sight and makes things visible

• Lighting - The process of igniting

• Energy Efficient Lighting - Producing the maximum amount of light while minimizing energy input.

History • In the beginning it was dark and cold . There was no sun , no light ,

no solar system . There was nothing , just the empty void of space.

The Sun – greater light for day• Then slowly , a huge cloud of gas and dust was formed. Eventually this cloud

contracted and grew into a central molten mass that became our Sun.

• Sun Light travels to the Earth in approximately 8  minutes from 93,000,000 miles away at 186,282 miles per second.

• The illumination on the earth's surface by the sun may exceed 100,000 lux in mid summer.

The Moon – lesser light for night• Light up the night

• The moon orbits the earth roughly once a month causing regular phases in a 29½ day cycle.   So calendars could be made, so people could plant their crops at the best time of the year

Early Life without light , there would be no life.. Life has dependant on Light ..

The Evaluation : Artificial Light • No Light – Mysteries Caves

• Dark – Household

The Evaluation : Artificial Light • Danger - Night Travel

• After Dark – No Work

Fire , Flame and Torch• Homo erectus probably discovered fire by accident when a bolt of lightning struck a

tree or a bush, suddenly starting it on fire.

• The flaming touch and the campfire probably constituted early man's first use of 'artificial' lighting.

• The torch was the first portable lamp. One of the earliest developments was the discovery that a bundle of sticks tied together made a blazing torch, producing a brighter and longer lasting light.

Prehistoric man, used primitive Prehistoric man, used primitive lamps to illuminate his cave. These lamps to illuminate his cave. These

lamps, made from naturally lamps, made from naturally occurring materials, such as rocks, occurring materials, such as rocks,

Why Energy Efficient Lighting ?• High Energy Bills

• Significant growth in Energy Demand

• Environmental Problems

• Lighting is a most visible form of Electricity Consumption

• Exhaustion of Electricity Generation Sources

• Lighting energy consumption

• 20-45% in commercial buildings

• 3-10% in industrial plants

• More Light from Less Power

Compact Fluorescent Lamp (CFL) • CFL is  a  compact  variant  of  the  fluorescent  lamp. 

• The overall length is shortened & luminous efficacy is about four times higher than that of incandescent lamps.

• It is possible to save energy and costs in lighting  by replacing incandescent lamps with  CFLs.

Simple ways to Conserve through lighting• Turn off lights – No Use

• Clean equipment

• Use dimmers , timers and occupancy sensors

• Controlling system – GSM / SCADA

• Use task lighting

• Buy Energy Star lighting products

• Save Energy - Save Money

Energy Saving Opportunities• Install energy efficient fluorescent lamp T-5 in place of conventional fluorescent

lamp T-12 / T -8

• Install  Energy Star Compact Fluorescent  Lamps (CFLs) in place of Incandescent Lamps

• Install LED Lamps in place of CFLs Install Electronic Ballast instead of Electromagnetic Ballast

• Install Induction / LED in place of High Pressure Sodium or Mercury / Metal Halide

• Use of high efficacy light sources for reducing the energy consumption for lighting

• Solar Powered – LED Lighting Systems
