Multi Color LED Lights

August 30, 2021

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.

1927

Russian inventor Oleg Lesev publishes theories on his findings and creation of the first LED.

1952

Prof. Kurt Lechovec builds on Lesev’s research.

1958

Egon Loebner and Rubin Braunstein create the first green LED.

1962

Nick Holonyak develops a red LED – the first to produce light within the visible spectrum – and the first LED is commercially available.

1964

IBM implements LEDs for the first time in circuit boards on the first computers.

1968

Hewlett Packard (HP) incorporate LED’s into their calculators.

1971

Edward Miller and Jacques Pankove create the first blue LED.

1972

Electrical Engineer M. George Craford creates the first yellow LED.

1986

Herbert Maruska and Walden C. Rhines at Stafford University create a functional blue LED with magnesium, and set the standard for the future.

1993

Physicists Isamu Akasi and Hiroshi Amano develop a blue LED using high quality gallium nitride.

Building on the research from Akasi and Amano, electrical engineer Shuji Nakamaura creates the first high brightness blue LED, an important precursor to the development of white LEDs.

2002

White LEDs for residential use become commercially available.

2008

LED lighting is more prevalent in schools, offices and hospitals.

2019

Halogen and fluorescent bulbs start to be phased out as LED becomes the dominant light source.
