White Papers and Presentations

As the leader in lighting control Lutron is striving to educate the industry about the importance of controlling LEDs and the compatibility issues that exist in the market today. Lutron is providing this education through webinars, conference sessions, magazine editorials, and more.


White Papers
Controlling LEDs
Explore all aspects of LED control, from the basics of LED function through the steps necessary to select the best light source and dimming options.

Challenges of Dimming LED Loads on ELV and MLV Transformers
This paper will explain the technical difficulties with dimming low-voltage LED lamps on magnetic and electronic transformers, and provide some design tips to improve the situation and avoid problems.

Dimming LEDs with Phase-Cut Dimmers: The Specifiers Process for Maximizing SuccessThe U.S. Department of Energy issued a report on the installation of LED lighting and controls at the Burden Museum in Troy, NY, a GATEWAY project installed in 2014. This case-study example shows how the proper selectionof products (including Lutron Grafik Eye QS dimmers) along with ensuring compatibility using available information (including Lutron’s LED Product Selection Tool) can lead to a successful installation.

TLED Lighting Scenarios for Retrofit Applications


 

Presentations
Lightfair 2016: Measuring what’s hard to describe: the latest research on flicker
Temporal Light Artifacts (TLA) —or more informally, flicker—is an often undesirable characteristic of lighting, whether visible or experienced as headaches and reduced productivity. With SSL lighting, and the near-instantaneous reaction of LEDs, TLA is easier to generate than ever. Causes include fluctuations in the mains voltage, driver design, and control compatibility issues, such as dimming with phase cut dimmers. Customer demand and recent industry work has brought this issue to the forefront of SSL designs. This presentation explains the current state of TLA research, and explains a better method to quantify this elusive characteristic as presented at Lightfair 2016.

Lightfair 2016: Dial in the Spectrum: Exploring Tunable White Lighting for a 911 Call Center
Optimizing the environment is critical to comfortably complete stressful tasks. As such, significant investment has been made into the ergonomics of 911 call centers, which include sit-to-stand desks, personalized HVAC, and customized user interfaces. However, lighting has remained essentially unaddressed until now. This presentation reports the results of a two-part study of the lighting in a 911 call center in Longmont, Colorado, which included the subjective assessment of glare, comfort, and preference using four different tunable white lighting applications as presented at Lightfair 2016.

Lightfair 2015: Proper Driver Selection in Integrated Designs
The choice of the LED driver used within an integrated lighting system determines many aspects of the performance of the system. Not only does the driver determine the control technology needed from the control system, but it also determines the best‐possible dimming performance available. Improper selection can degrade the customer's experience with the lighting control system, and can cause costly and disappointing end results. This presentation reviews the important aspects to look for when selecting or specifying drivers as part of an overall lighting control system. As presented at Lightfair 2015.

CEDIA Expo 2014: Become an LED Lighting and Controls Expert
Adoption of LED lighting continues to accelerate in every application. Learn about the important characteristics of LED lighting, and how Lutron can help you design,install, and commission LED lighting systems that work well and are profitable.

Lighting Sommeliers: Pairing Integrated Solid-State Lamps and Dimmers in Existing Spaces
The gold standard of interior dimming is the incandescent lamp with its smooth dim to zero, no flicker, acceptable color shift, easy maintenance, and positive impacts on lamp life. How close are integrated LED lamps to matching that standard? How do lighting designers simultaneously maintain visual quality for the user without compromising the building’s electrical infrastructure? Are LED’s costing owners more money than they are saving? This course will provide an overview of the complex electronics utilized in solid-state lighting devices and explore the more challenging aspects of integrated solid-state lamp and dimmer interactions. As presented at Lightfair 2013.

Lightfair 2013: Using NEMA SSL‐7A to improve LED dimming
Attempts to dim commercially available LED sources with phase-control dimmers continue to show less than desirable results. This presentation will review a recently released industry standard, NEMA SSL 7A, that aims to improve LED dimming compatibility.It provides a background and history of dimming compatibility challenges, as well as a summary of the tests defined within the standard, and how they relate to commonly-experienced LED dimming problems. As given at Lightfair 2013.

Lightfair 2012: Dimming LED sources
LEDs are inherently capable of being dimmed. Nevertheless, attempts to dim many commercially available LED products with existing dimmers and infrastructure still frequently result in confusion and frustration. The issues behind these experiences can be overcome, but only with continued manufacturer and designer efforts. This presentation will provide technical background on the problems, including a review of recent industry developments and their impact, advice on how to make trade-offs and avoid problems, and suggestions for how all industry players can contribute to increased success in LED dimming projects. As given at Lightfair 2012.
