ASSIST: Research Activities


ASSIST funds a wide range of research projects in LED lighting. These projects are designed to understand the basics of LED life, performance, and user preferences in order to better apply this technology to create successful, real-world lighting applications. Understanding LED performance is key to ensuring the maximum potential and future of LED lighting.

In the past five years, ASSIST has focused on issues of color, flicker, application and benefit metrics, outdoor lighting, and education.

Recent ASSIST-funded projects include:

ASSIST Application & Benefit Metric Guides (2015)
ASSIST has developed short design guides that suggest alternative ways to evaluate and compare LED solutions with traditional lighting technologies. The suggestions focus on how application metrics and benefit metrics can be used and contrasted to typical light source or luminaire metrics when assessing the effectiveness of different lighting options at meeting the design objectives.

ASSIST recommends… Assessing Direct Perception of Flicker pdf logo (2015)
ASSIST has proposed a new method for measuring and quantifying direct perception of light source flicker.

ASSIST recommends… Light Source Flicker: Application Considerations pdf logo (2015)
ASSIST has published a guide describing experimental data that illustrate how detection and acceptability of stroboscopic effects change under different conditions that might be more applicable to certain lighting applications.

Measuring LED Lens Surface Temperature with Thermocouples pdf logo (2014)
The LRC conducted a study to understand the problems in using thermocouples to measure LED lens surface temperature and to find a solution to improve measurement accuracy.

Parking Lot Lighting with Improved Uniformity (2015)
In this study, the Lighting Research Center sought to better understand the energy and user acceptance benefits of high illuminance uniformity on outdoor area or parking lot lighting.

Understanding White Light Source Color Rendering and Appearance (2014)
For the past decade, the LRC and ASSIST have conducted a long-term study of subjective preferences using psychophysical experiments to understand how observers perceive white light sources and what they prefer in terms of object color rendering and the white hue or tint of a light source.

Professional LED Lighting Education (2x per year)
In 2001, the LRC began offering the first unbiased, research-based workshop for lighting designers, architects, and engineers on how to build successful LED lighting products and applications.

LED Lighting Summer Internship for Undergraduates (every summer)
An eight-week paid summer internship program for undergraduates and recent graduates from engineering, physics, science, architecture, or industrial design who are interested in conducting research and learning more about the LED lighting field.
