LED History & Evolution

Light Emitting Diodes or LEDs operate very differently to filament lamps, discharge lamps and fluorescent tubes.
They operate by 'Injection electroluminescence', a phenomenon first observed in 1907 by H. J. Round
experimenting with Silicon Carbide. However, as he was really looking for new ways of radiolocation in
seafaring, his discovery was completely forgotten about.
It wasn't until 1962 that the first red LEDs were invented.
The first digital watch, the 1972 Pulsar 'Time Computer', used LEDs
for its display.
By the mid 70's other colours had joined red including yellow,
orange and green, although the efficiency and light output was
still very poor.
Between 1970 and 1995 the light output of red LEDs increased by a
factor of approx. 45 and between 1995 and 2003 the efficiency of LEDs
increased by an average factor of 16 and the light output per LED
package by a factor of 430.
LED History & Evolution
The net result is that today LEDs have the efficiency and light output to be considered for many varied
applications including traffic signals and signs, large area video displays and car instrument and switch
Since 2005 further developments have seen a rapid growth in the use of LEDs for higher levels of illumination.
For example LEDs will replace incandescent lamps (including headlamps) in cars by 2010.
LEDs are already used for general lighting applications and decorative lighting and will replace some
conventional light sources in the near future.

What is a Light Emitting Diode?

A Light Emitting Diode (LED) is a 'solid state' electronic component with the characteristics of a diode i.e. it only allows electrical current to flow in one direction through it. When the current flows through an LED in the correct direction, the LED produces light of a specific colour.

LED's only produce light of certain specific colour. Due to a variation on the method used to manufacture LEDs that emit white light different colour temperatures are available - e.g. 6500 K, 5400 K, 4700 K, 3300 K and 2700 K. Contact us to book a free LED Lighting Design consultation.
