Understanding LED Dimming Techniques and Technology

The Basics of LED Dimming: An Introduction Understanding LED dimming techniques starts with grasping the basics of how LEDs function. Unlike traditional incandescent bulbs, LEDs don’t use a filament. They work by passing an electrical current through a semiconductor, which then emits light. Dimming in LEDs is achieved by manipulating this current. However, not all […]

The Evolution of LED Lighting: A Historical Overview

The Origins of LED Technology: A Revolutionary Discovery The evolution of LED lighting begins with its inception in the early 20th century. The discovery of the light-emitting diode (LED) was a pivotal moment in lighting technology, marking a shift from traditional incandescent and fluorescent lights. In 1907, H.J. Round, a British experimenter, first observed electroluminescence, […]

Economic and Safety Benefits of LED Street Lighting in American Cities

Los Angeles has already converted more than 75% of its more than 200,000 street light to LED technology. Chicago, New York, Shanghai, and Copenhagen are well into plans to convert their own street lighting to LED’s. Other smaller cities around the globe are considering the same thing. Cities that retrofit their street lighting to LED […]

Improving the Heat Sink in Modern LED Fixtures

Many people understand that LED lighting uses fixtures that are cooler to the touch than traditional incandescent light bulbs. LED lights do not generate light in the infrared spectrum and are, in fact, both cooler and more efficient than incandescents. Unlike traditional light bulbs that typically convert less than 10% of electrical energy input into […]

Thermal Management for LED Lighting Efficiency

From its first inception, artificial lighting has been notoriously inefficient. The first generations of incandescent lighting converted less than 5% of electrical power input into light, with the remaining power being dissipated as excess heat. Over time, efficiency improvements improved that number only slightly for incandescent fixtures but new lighting technologies, including LED systems, made […]

Adjusting Street Lighting to Accommodate the AMA’s Health Concerns

A recent study published by the American Medical Association (AMA) might have dimmed the ardor of municipalities that have been considering retrofitting their street lighting to LED systems. The AMA has specifically cautioned that because of their brightness, LED lights create more glare that leads to eyestrain and fatigue. Further, the Association has cautioned that […]

The Slow Death of Metal Halide Lights

Metal halide lights have been the de facto standard for illumination of outdoor and large indoor spaces for more than fifty years. Sports arenas, in particular, have relied on metal halide and similar technology to illuminate playing fields and arenas, but as that technology has aged, the operators of those facilities are seeing its drawbacks. […]

How Television Broadcasts Benefit from LED Lighting

The advent of high definition television broadcasts marked a quantum leap in television broadcast technology and quality. Producers of those broadcasts have scrambled to retrofit other parts of their broadcast platforms to match high definition quality. Transitioning to LED lighting has generally given broadcasters a high return with noticeable improvements in broadcast quality and broadcasts […]

LED Lighting for Department of Transportation Compliance

The United States Department of Transportation’s (DOT) lighting standards for commercial traffic and other motor vehicles place a priority on safety to ensure transportation compliance. For example, Standard 108 under Part 571 of the Federal Motor Vehicle Safety Standards and Regulations, which addresses vehicle lighting, states that its purpose is to “reduce traffic crashes and […]

Museums are Using LED Technology to Preserve Paintings

In 2015, Germany’s Aachen Cathedral, joined the growing list of art museums and other historical heritage sites to transition to LED museum lighting. The Cathedral, which is the burial place of Prince Charlemagne, maintains a collection of art and artifacts that date back to Europe’s pre-Renaissance era. Like other museums that have also adopted LED […]
