Nick Holonyak Jr. (/ h ʌ l ɒ n j æ k / huh-LON-yak; November 3, 1928 – September 18, 2022) was an American engineer and educator.He is noted particularly for his 1962 invention and first demonstration of a semiconductor laser diode that emitted visible light.
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. [5] 1994 The first commercial sulfur lamp is sold by Fusion Lighting.
[8] [9] He was the first to propose Radium as a treatment for cancer. [10] In 1903, he and Dr. Willy Meyer used radium to treat an incurable tumor, and it was observed to shrink and become less painful, though the patient was not cured. [11] He invented the luminous Radium dial for watches and other instruments, widely used in World War 1 and ...
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 ...
The first blue-violet LED, using magnesium-doped gallium nitride was made at Stanford University in 1972 by Herb Maruska and Wally Rhines, doctoral students in materials science and engineering. [32] [33] At the time Maruska was on leave from RCA Laboratories, where he collaborated with Jacques Pankove on related work. In 1971, the year after ...
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.
An engineer made history as Georgia Tech’s first Black graduate; 59 years later, he passes the torch to his granddaughter Ashley R. Williams, CNN May 5, 2024 at 8:46 PM
M. George Craford (born December 29, 1938) is an American electrical engineer known for his work in Light Emitting Diodes (LEDs).. Raised in an Iowa farming community, he studied physics at the University of Iowa, where he earned his BA in 1961.
