There are a considerable number of patents issued for extending the life of light bulbs; the first appears to be Ole Nillson's "Lamp Life Extender," number 4229680, issued in 1980.
Improvements, however, started before the 1890s, well before Edison was stripped of all of his stolen light-bulb patents in 1893.
