STREET LIGHTS: Patents from 1964 |
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 mid 1960s saw many refinements and innovations. There are so many patents that we only have room for one year per page. As technology developed there was an additional drive to achieve greater efficiency, producing more usable light in more desirable directions for each watt of power used. |
