2. INTRODUCTION
In the first part we will talk
about the history of the light
bulb,
Then we will look the light
bulb created by Thomas Alva
and its history, at the parts of
this,
we will make some
comparisons the light bulb
and how its changed over
time
and finally we will talk about
that the light bulb had many
uses and some ideas about
it,
3. HISTORY
More than 150 years ago, inventors began working
on a bright idea that would have a dramatic impact on
how we use energy in our homes and offices. This
invention changed the way we design buildings,
increased the length of the average workday and
jumpstarted new businesses. It also led to new
energy breakthroughs -- from power plants and
electric transmission lines to home appliances and
electric motors.
Like all great inventions, the light bulb can’t be
credited to one inventor. It was a series of small
improvements on the ideas of previous inventors that
have led to the light bulbs we use in our homes today.

7. CHANGES
The change more
important about of light
bulbs is the prohibition
around of world for
lighting in favor of
energy-efficient lighting
alternatives, for this
the government in
some countries has
laws about it
8. ITS USE AT THE MOMENT
2009 European Union 100W
2010 European Union 75W
2011 European Union 60W
2012 European Union 25 - 40W
20th century
(XIX)

9. SOME IDEAS
if we were good for save energy with lights
bulbs, would the better world,
if we were recycle the old lights bulbs, would
help improve global warming,
if we were turn off the lights that not use,
would save energy
If we use energy saving lights , we would
help a better future
10. CONCLUSION
The incandescent light bulb change the world
One can’t talk about the history of the light bulb
without mentioning William Sawyer and Albon
Man. Other scientist.
Discharge lamps became the basis of many
lighting technologies, including neon lights, low-
pressure sodium lamps and fluorescent lights
One of the fastest developing lighting
technologies today is the light-emitting diode (or
LED).
