3. ABSTRACT:
This paper deals with the energy saving potential possible with changing in illumination schemes. The case study
in an engineering institute deals with the replacement of existing conventional lighting scheme with LED lighting
scheme will have huge energy saving potential, with pay back period of even less than 18 months. The LED
lighting scheme provides additional advantages as cool light, decreased maintenance cost, longer life, more
flexibility, easier handling With increase in energy crisis there is a need of looking for additional energy sources
or reduce in energy consumption in any form without loosing comfort. It is always preferred over energy
conservation over energy generation, as energy generated is many fold energy generated. Energy audition is the
new trend in the present scenario. An energy auditor can play a major role in energy saving. Energy saving
potential is possible at every part of life. One of the energy saving scheme in illumination is, by using natural
light and/or use of LEDs. LEDs are having major advantages of longer life & almost negligible power
consumption compared to any type of illuminating source(s).

4. OBJECTIVE:
Energy saving reduces costs to households and to businesses, increasing sustainability of the local
economy and community. The potential for building local expertise on renewable energy, becoming a
test-bed for new technologies, thus creating limited local employment, with the possibility of
exporting expertise.

5. INTRODUCTION
 In an average home, about 20% to 40% of energy are consumed by light sources. while it’s not
much comparing to other applications, it’s something we can control.
 A decade ago, the main choice for lighting were incandescent bulbs.
 That days are long gone, now there are option which are more efficient than incandescent bulbs.
 The energy efficient alternatives were released a few years back to consumers.
 They provide more light per energy consumed and have longer life span.

6. CONVENTIAL:
 An incandescent light bulb is an electric light with a wire filament heated to such a high
temperature that it glows with visible light.
 They are not efficient because about 90% of the energy it uses Is dissipated as heat,
which means only 10% of the energy it consume is converted to light.

7. PROPOSED:
 Energy saving tubes or light sources provide same or better lighting and consumes
significantly less power.
 The main alternatives that emerging now are LED bulbs and tubes.

8. BLOCK DIAGRAM:

9. WORKING
 LED bulbs and tubes consist of 1 or more LED(Light Emitting Diodes).
 A light-emitting diode is a two-lead semiconductor light source.it is a p-n junction diode that emits
light when activated.
 When a suitable voltage is applied to the leads, electron holes within the device, releasing energy
in the form of photons.

11. COMPARISION:
 Compared to incandescent bulbs and fluorescent bulbs, LED light provide more lights
per watt(Lumens per watt).
 LED lights are more long lasting than others.
 Contain no harmful chemical.
 Less heat output.

12. ADVANTAGES:
 Energy efficient
 Long lasting
 No lasting
 No harmful chemicals
 Available in variety of light types.

13. DISADVANTAGES:
 Initial cost is high compared to incandescent and CFL.
 Light slightly dependent an ambient temperature.

14. FUTURE SCOPE:
 Using these energy saving lighting solutions in street, public areas can reduce the energy
consumption.
 Replacing all lightings at home with these can drastically reduce energy bills.

15. CONCLUSION:
 At these time where number of electronics are increasing, saving energy from anywhere is a good
thing.
 These energy saving lighting solutions will surely help in achieving that also reducing the future
energy shortage.
