Meeting LM-79 Requirements for LED Testing

Introduction to Meeting lm-79 Requirements for LED Testing

LED lighting has become increasingly popular in recent years due to its energy efficiency and long lifespan. However, in order to ensure that LED lighting products meet safety and performance standards, they must be tested according to the lm-79 standard. This standard is a set of requirements for testing LED luminaires, and it is important for manufacturers to understand and meet these requirements in order to ensure their products are safe and effective. In this article, we will discuss the LM-79 requirements for LED testing and how manufacturers can ensure they are meeting these requirements.

What is LM-79?

LM-79 is a standard developed by the Illuminating Engineering Society (IES) that outlines the requirements for testing LED luminaires. This standard is used to ensure that LED lighting products meet safety and performance standards, and it is important for manufacturers to understand and meet these requirements in order to ensure their products are safe and effective. The LM-79 standard includes requirements for testing the electrical, optical, and thermal characteristics of LED luminaires.

Electrical Testing Requirements

The LM-79 standard includes requirements for testing the electrical characteristics of LED luminaires. This includes testing the input power, input current, input voltage, and power factor of the luminaire. It also includes testing the efficiency of the luminaire, which is the ratio of the output light to the input power.

Optical Testing Requirements

The LM-79 standard also includes requirements for testing the optical characteristics of LED luminaires. This includes testing the luminous flux, color temperature, color rendering index, and beam angle of the luminaire. It also includes testing the efficacy of the luminaire, which is the ratio of the output light to the input power.

Thermal Testing Requirements

The LM-79 standard also includes requirements for testing the thermal characteristics of LED luminaires. This includes testing the temperature of the luminaire, as well as the temperature of the surrounding environment. It also includes testing the thermal resistance of the luminaire, which is the ratio of the temperature difference between the luminaire and the surrounding environment to the power dissipated by the luminaire.

How to Meet LM-79 Requirements

In order to ensure that LED lighting products meet the LM-79 requirements, manufacturers must use specialized testing equipment and procedures. This includes using a photometer to measure the luminous flux, a spectroradiometer to measure the color temperature and color rendering index, and a thermometer to measure the temperature of the luminaire and the surrounding environment. Manufacturers must also use specialized software to analyze the data collected during the testing process.
