One of the first mercury vapor lamps invented by Peter Cooper Hewitt, 1903. It was similar to a fluorescent lamp without the fluorescent coating on the tube and produced greenish light. The round device under the lamp is the ballast. Thomas Edison briefly pursued fluorescent lighting for
Cooper Hewitt lamp, 1903 Production of high-pressure mercury-vapor lamps, 1965. Charles Wheatstone observed the spectrum of an electric discharge in mercury vapor in 1835, and noted the ultraviolet lines in that spectrum. In 1860, John Thomas Way used arc lamps operated in a mixture of air and mercury vapor at atmospheric pressure for lighting. [4]
The parent to the modern fluorescent lamp was invented in the 1890s by Peter Cooper Hewitt. [6] The Cooper Hewitt lamps were used for photographic studios and industries. [6] Edmund Germer, Friedrich Meyer, and Hans Spanner patented a high-pressure vapor lamp in 1927. [6]
One of the first mercury arc bulbs built by Cooper Hewitt. In 1882 Jules Jamin and G. Maneuvrier observed the rectifying properties of a mercury arc. [4] [5] The mercury arc rectifier was invented by Peter Cooper Hewitt in 1902 and further developed throughout the 1920s and 1930s by researchers in both Europe and North America.
