This document discusses energy efficient lighting and provides a brief history of light and lighting technologies. It describes early lighting methods such as fire and torches. Modern technologies discussed include compact fluorescent lights (CFLs), induction lighting, and LED lighting. These new lighting methods use 40-60% less energy than traditional incandescent bulbs and last much longer. The document provides examples of energy efficient lighting being used for street lights, signage, and other applications. It emphasizes that switching to energy efficient lighting can provide significant energy savings.

2. Presentation Agenda
• History of Light and Lighting
• Lighting Technology
• Energy Efficient Lighting
• Compact Florescent Light
• Induction Lighting
• LED Lighting
• Energy Efficiency

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. 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. 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.

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. Image of the Earth at night
Early Life without light , there would be no life.. Life has dependant on Light ..

8. The Evaluation : Artificial Light
• No Light – Mysteries Caves
• Dark – Household

9. The Evaluation : Artificial Light
• Danger - Night Travel
• After Dark – No Work

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 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.

11. Primitive Lamps
Prehistoric man, used primitive
lamps 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. Oil Pottery Lamps
An oil lamp is an object used to
produce light. continuously for
a period of time using an oil-
based fuel source. The lamp
made up by pottery wheel and
molding techniques.

13. Candle
A candle is a solid block of wax
with an embedded wick, which
is ignited to provide light.

14. Kerosene Lamp
The kerosene lamp is a type of
lighting device that uses
kerosene as a fuel.

15. Invention of the Light Bulb

16. Lighting Technology Continues…

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. 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. Energy Efficient Lighting
Induction Lighting LED Lighting
• Disbursed Light • Highly Directional Light
• Energy Saving 40 – 60% • Energy Saving 40 – 60 %
• Life – 100,000 • Life – 50,000
Applications Applications
• Indoor Lighting • Indoor / Outdoor Lighting
• Outdoor Lighting • Signage
• Tunnel Lighting • Specialized Applications

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. Induction Lighting – Applications

22. LED Lighting – Benefits & Features
• Cycling
• Dimming
• Energy Savings
• Size and Focus
• Green Product – No Harm Emissions
• Long Life
• Lower Temperatures
• Shock Resistance

23. LED Applications

24. Case Study
Induction Lighting

25. Case Study
Induction Street Lighting

26. Case Study
LED STREET LIGHTING

27. Case Study
LED SIGNAGE

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. 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
