biography

Beginnings and private matters

Leighton was the son of Wallace Leroy and Mabel Violet, née George, Leighton. Born in Jacksonville, Florida, Leighton attended the University of Florida in 1935 , where he graduated with a degree in engineering. Leighton married in 1936 and the following year became a test engineer at the General Electric Company in Schenectady , New York, where he later became head of the incandescent lamp design engineering group at Nela Park. In 1977 the father of the family (he and his wife had two daughters) withdrew from working life.

Professional background

In 1958/59 Leighton, together with his colleague Don W. Prideaux and the Lamp Division of General Electric Co., had the honor of being awarded an Oscar plaque. The duo received the award for the design and production of an improved 10-kilowatt incandescent lamp for lighting films. The design of this lamp was based on US Pat. No. 2,933,632 to Leighton, which used a collector screen (or optical grating ) placed over the filament . The sieve that was now in place allowed tungsten atoms and particles convex over the filament to be captured. This led to an improved light output with a longer burning time as well as a reduction in the excessive heating and bubble formation on the glass surface above the filament. The lamp also had a Bipost structure for the power supply. The collector shade lamp was very large. This general improvement greatly increased the ability to record a movie for a much longer period of time at a near constant level of light.

Leighton, who had ten patents, also received the patent for a so-called "sawmill cleat". When this lamp is mounted directly above a cutting table, a line is visible on the table that represents the image of the straight tungsten wire, providing a reference line for cutting.
