A Brief History of the LED

LEDs (light emitting diodes) have been most commonly accepted as a 1927 discovery, when a Russian radio technician noticed that the diodes on a radio receiver emitted light when current passed through.  For many years thereafter, the LED remained in small scale applications, primarily as laboratory electronic testing equipment, and then on to indicator lights for devices using a circuit board, such as your VCRs, TVs, calculators, radios, watches, etc. 

For many years, things stayed this way for LEDs, and there was little advancement of LED technology.  We watched the common lighting technology (such as incandescent, fluorescent, metal halide) improve, but there was really no significant change to the underlying technology of how we commonly produce light.  Then came along the early 1990s and the explosion of the microchip.  As circuit boards became much more advanced, efficient, and affordable, researchers and engineers began applying this technology to the LED.  LEDs began gaining ground in commercial application, although still on a smaller scale. 

In the past decade, and primarily in the past few years, High Output LED technology has changed the way we think about lighting, and we are currently on the verge of a lighting revolution.  LED chips have become increasingly resilient, efficient, and combined with heat syncs in order to handle higher voltages and currents very efficiently (in addition to both alternating and direct current, or AC and DC power, at the fixture level).  Because of the nature of solid-state technology, light can be controlled very easily, and much more light can be produced with much less electricity than traditional incandescent and fluorescent lighting.  The potential to drastically reduce carbon emissions and mercury disposal has never been greater as LED technology improves and becomes more common in general purpose applications.

We now see LED lighting home and also many commercial and industrial applications.  While LED technology is still more expensive than traditional lighting, initially, many home owners, building managers, contractors, and large facility owners are realizing that it is simply an initial cost and an investment.  A very prudent investment, often with a 2 to 5 year payback and thousands of dollars in savings over the lifespan of the lights (35,000 - 50,000 hours).
