  1. Filament Bulbs: endangered species? “Green” light Team N.T.A.M.A4th High School of Chania ΝikoletaMavredakiTriantafilliaPsaroudakiAlkistiKapnisakiMarina ChoustoulakiAnna-Maria Papasifaki

  2. Overview • Literature search of incandescent light bulbs • Experiments comparing four different types of light bulbs • Questionnaire • Poster

  3. From natural to artificial

  4. From natural to artificial Lascaux oil lamp replica made of red sandstone http://cart.occpaleo.com/lascauxoillampreplica.aspx

  5. From natural to artificial Diogenes of Sinope 323 B.C. First filament bulb by Thomas Edison

  6. Inventors of filament bulbs Thomas Edison American Inventor Josef Swan British Physicist and Chemist

  7. Inventors of filament bulbs Heinrich Gӧbel German mechanic and inventor inventor of the first true electrical light bulb in 1850 but he did not applied for a patent

  8. Filament bulbs Tungstenfilament wire Heated to a high temperature • Bulb glows http://www.nomenclaturo.com/electric-electricity

  9. Halogen bulbs • The tungsten filament lasts longer. • Their lifespan is reduced when we touch them with bare hands. http://visual.merriam-webster.com/house/electricity/lighting/tungsten-halogen-lamp.php

  10. Kyoto protocol Kyoto Protocol participation map • International environmental treaty • Target : phase out completely the use of incandescent filament bulbs • Developing countries • Developed countries that agreed to meet binding targets • Developed countries that have not ratified the protocol • Developed countries that have renounced the protocol

  11. Experimental procedure Halogen Filament • We measured: • Electrical current • Temperature • Spectrum 700 Lumen L.E.D C.F.L

  12. Experimental setup

  13. Temperature measurement: Loss of heat Temperature (oC) Type of Bulb

  14. Spectral radiance

  15. Comparative calculations

  16. Conclusion

  17. Questionnaire • Attitude • Preferences • Awareness • Knowledge

  18. Sample population

  19. Respondent demographic profile

  20. POSTER Increasing public awareness • In schools • In companies
