Thomas Edison briefly pursued fluorescent lighting for its commercial potential. He invented a fluorescent lamp in 1896 that used a coating of calcium tungstate as the fluorescing substance, excited by X-rays. Although it received a patent in 1907, [6] it was not put into production. As with a few other attempts to use Geissler tubes for ...
Circular and U-shaped lamps were devised to reduce the length of fluorescent light fixtures. The first fluorescent light bulb and fixture were displayed to the general public at the 1939 New York World's Fair. The spiral CFL was invented in 1976 by Edward E. Hammer, an engineer with General Electric, [7] in response to the 1973 oil crisis. [8]
1991 Philips invents a fluorescent lightbulb that lasts 60,000 hours using magnetic induction. 1994 T5 lamps with cool tip are introduced to become the leading fluorescent lamps with up to 117 lm/W with good color rendering. These and almost all new fluorescent lamps are to be operated on electronic ballasts only. [4]
An electric light, lamp, or light bulb is an electrical component that produces light.It is the most common form of artificial lighting.Lamps usually have a base made of ceramic, metal, glass, or plastic which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well.
Edward E. Hammer (December 27, 1931 – July 16, 2012) [1] was an engineer who was at the forefront of fluorescent lighting research. His technological contributions in incandescent, fluorescent and HID light sources earned him over 35 patents. [2] He received his bachelor's degree from Manhattan College in 1954.
Edmund Germer (August 24, 1901 – August 10, 1987) was a German inventor, recognized as the father of the fluorescent lamp.His father was an accountant. He obtained a doctorate from the University of Berlin in lighting technology.
BOSTON - The northern lights have put on a show in 2024. In May, the strongest solar storm in 21 years set off the aurora borealis and on Thursday night, the stunning colors were visible once ...
The Moore lamp was the first commercially viable light-source based on gas discharges instead of incandescence; it was the predecessor to contemporary neon lighting and fluorescent lighting. [1] In his later career Moore developed a miniature neon lamp that was extensively used in electronic displays, as well as vacuum tubes that were used in ...
