STREET LIGHTS: Patents from 1965 |
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. |
In 1965 there was a drive to develop combination systems combining street light lumiares and residential service transformers. Also shallow bowl refractors were developed in an effort to provide lighting from pendant luminaires that was similar to that provided by ovate (clamshell) and cobrahead luminaires. |
