Up until the early 2000’s any kind of colourful lighting was typically limited to theatre and performance applications. However as LED technology made significant leaps during that time, the realm of possibilities has since expanded to commercial, architectural and even domestic applications. As a result
it is now common to see colourful lighting installations outside of entertainment districts and in areas where previously it was not feasible.
A Brief History of Multi-color LED Lights
For those outside of the lighting or electronic industries, Light Emitting Diodes or LED’s may appear to be a 21st century invention. However LED’s were first created in 1927 and have been in development ever since then.
Egon Loebner and Rubin Braunstein create the first green LED.
IBM implements LEDs for the first time in circuit boards on the first computers.
Electrical Engineer M. George Craford creates the first yellow LED.
Herbert Maruska and Walden C. Rhines at Stafford University create a functional blue LED with magnesium, and set the standard for the future.
Physicists Isamu Akasi and Hiroshi Amano develop a blue LED using high quality gallium nitride.
Halogen and fluorescent bulbs start to be phased out as LED becomes the dominant light source.
