Light Bulbs by Mind Map: Light Bulbs

1. Invention

2. WHY? The idea that light could be created with electricity was sure of at the time but there was no proof of it so many people tried to create a new way for light through electricity

3. How does it work?

4. An incandescent light bulbis made of a glass enclosure containing a tungsten filament. An electric current passes through the filament, heating it to a temperature that produces light

5. Parts of a Light Bulb

6. Innovation?

7. The light bulb was improved in 1990s when they were more efficient and had longer life than the original. These were called Compact Fluorescent bulbs

8. Incandescent bulbs weren't very energy efficient because less than 10% of electricity supplied to the bulb was converted into visible light. The remaining energy was lost as heat. This is why the need to improve the light bulb came.

9. Types of Light bulbs

10. Incandescent

11. Luminescent

12. Discharge

13. SSL (LED)

14. Impacts

15. Uses (Then vs Now)

16. Social

17. Cultural

18. Political

19. Environmental

20. With the invention of the light bulb, the invention of many other technology was also possible such as the smartphone, television, computers, etc.

21. The environment is affected a lot because a lot of processed material is required to make the light bulb and this affected rivers, forests, and many other landscapes because of deforestation and river dumping

22. As the invention of the light bulb evolved, only the powerful countries could afford to switch all the resident's gas lamps with the electric bulbs so this divided the politics of the world

23. They would also need to supply electricity to power the bulbs

24. THEN: The invention of the light bulb sparked many other inventions that we use today

25. THEN: Used to light up small areas because it wasn't powerful enough

26. NOW: Powerful lights can light up large areas for greater efficiency

27. NOW: Research is being done to improve the light bulb's efficiency and energy use.

28. Economic

29. The invention of the light bulb meant that people could continue working in large areas (factories, etc.) because they had a light source to work in. More work could be done so more goods were produced.

30. WHO? The light bulb was invented by Thomas Edison
