Energy Efficient Lighting

  1. 1. Energy Efficient Lighting By Mohammed Mohasin Shaik www.shaikmohasin.wordpress.com
  2. 2. Presentation Agenda• History of Light and Lighting• Lighting Technology• Energy Efficient Lighting• Compact Florescent Light• Induction Lighting• LED Lighting• Energy Efficiency
  3. 3. 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.
  4. 4. 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.
  5. 5. 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 earths surface by the sun may exceed 100,000 lux in mid summer.
  6. 6. 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
  7. 7. Image of the Earth at nightEarly Life without light , there would be no life.. Life has dependant on Light ..
  8. 8. The Evaluation : Artificial Light• No Light – Mysteries Caves• Dark – Household
  9. 9. The Evaluation : Artificial Light• Danger - Night Travel• After Dark – No Work
  10. 10. 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 mans 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.
  11. 11. Primitive Lamps Prehistoric man, used primitivelamps to illuminate his cave. These lamps, made from naturally occurring materials, such as rocks,shells, horns and stones, were filled with grease and had a fiber wick. Lamps typically used animal or vegetable fats as fuel.
  12. 12. Oil Pottery LampsAn oil lamp is an object used toproduce light. continuously for a period of time using an oil- based fuel source. The lampmade up by pottery wheel and molding techniques.
  13. 13. CandleA candle is a solid block of waxwith an embedded wick, which is ignited to provide light.
  14. 14. Kerosene LampThe kerosene lamp is a type of lighting device that uses kerosene as a fuel.
  15. 15. Invention of the Light Bulb
  16. 16. Lighting Technology Continues…
  17. 17. 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
  18. 18. 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.
  19. 19. Energy Efficient LightingInduction Lighting LED Lighting• Disbursed Light • Highly Directional Light• Energy Saving 40 – 60% • Energy Saving 40 – 60 %• Life – 100,000 • Life – 50,000Applications Applications• Indoor Lighting • Indoor / Outdoor Lighting• Outdoor Lighting • Signage• Tunnel Lighting • Specialized Applications
  20. 20. Induction Lighting – Benefits & Features• Longer Life Span• High Energy Conservation• High Power Factor• Low Maintenance Problems• Minimum Lumen Depreciation• Instant On and Off• Environmental Friendly
  21. 21. Induction Lighting – Applications
  22. 22. LED Lighting – Benefits & Features• Cycling• Dimming• Energy Savings• Size and Focus• Green Product – No Harm Emissions• Long Life• Lower Temperatures• Shock Resistance
  23. 23. LED Applications
  24. 24. Case StudyInduction Lighting
  25. 25. Case StudyInduction Street Lighting
  26. 26. Case StudyLED STREET LIGHTING
  27. 27. Case StudyLED SIGNAGE
  28. 28. 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
  29. 29. 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
  30. 30. Change a light ,Change the World.. Thank You ALL
