LED (Light Emitting Diode) lighting may seem like a modern innovation, but its origins trace back nearly a century. First discovered in the 1920s, LED technology has evolved dramatically to become the most energy-efficient and widely used lighting solution for homes, offices, schools, and hospitals today.
At Netzo Lighting, we’re proud to supply the very best in high-performance LED luminaires, but how did we get here? Let’s take a look at the key milestones in the history of LED lighting.
A Timeline of LED Lighting Innovation
1927 – Russian inventor Oleg Losev reports the creation of the first light-emitting diode, publishing early theories on electroluminescence.
1952 – Professor Kurt Lehovec tests and expands on Losev’s work, helping define how LEDs function.
1958 – Egon Loebner and Rubin Braunstein develop the first green LED.
1962 – Nick Holonyak Jr. creates the first red LED on the visible light spectrum, widely considered the first practical LED.
1964 – IBM incorporates LEDs into early computer circuit boards for indicator lights.
1968 – Hewlett-Packard (HP) begins using LEDs in calculators, marking their first consumer electronics application.
1971 – Edward Miller and Jacques Pankove develop an early version of the blue LED.
1972 – Electrical engineer M. George Craford invents the first yellow LED, adding to the colour range.
1986 – Researchers Herbert Maruska and Walden C. Rhines create a reliable blue LED using magnesium, setting new standards for efficiency.
1993 – Isamu Akasaki and Hiroshi Amano enhance blue LED performance using gallium nitride. Their work enables Shuji Nakamura to develop the first high-brightness blue LED, paving the way for white LED lighting.
2002 – White LEDs become available for residential use, though early versions cost between £80–£100 per bulb.
2008 – LED lighting gains popularity in education, healthcare and commercial environments thanks to its low energy usage and long lifespan.
2019 – LED lighting becomes the dominant light source, with halogen and fluorescent bulbs gradually phased out across the UK and globally.
