Street Light Technical Information

Patents from 1920 through 1924

Patents are an effective way to understand the development of street lighting in the United States. In this section I have posted patents as I located them. (Early patents are difficult to locate as they were not cross-indexed.)

All patents are listed in order of their filing dates. Click on the patent number or thumbnail to view the entire patent.

The "Roaring Twenties" were also roaring for street lamp inventors. There were so many patents filed that we've had to break this decade into multiple pages.
