Accurately Measuring LED Luminance with Photometers

Introduction to Accurately Measuring LED Luminance with Photometers

LEDs are becoming increasingly popular in the lighting industry due to their energy efficiency and long life. However, it is important to accurately measure the luminance of LED luminaires to ensure that they are providing the desired level of illumination. Photometers are the most accurate way to measure the luminance of LED luminaires, as they measure the amount of light emitted from the luminaire in a specific area. This article will discuss the importance of accurately measuring LED luminance with photometers, as well as the different types of photometers available and how to use them.

Types of Photometers

There are two main types of photometers used to measure LED luminance: handheld and stationary. Handheld photometers are small, portable devices that can be used to measure the luminance of LED luminaires in a variety of locations. Stationary photometers are larger, more expensive devices that are typically used in laboratories or other controlled environments. Both types of photometers measure the amount of light emitted from the luminaire in a specific area, and can be used to accurately measure the luminance of LED luminaires.

How to Use Photometers to Measure LED Luminance

Using a photometer to measure LED luminance is relatively simple. First, the photometer must be calibrated to the specific LED luminaire being tested. This is done by adjusting the photometer’s settings to match the luminaire’s specifications. Once the photometer is calibrated, it can be used to measure the luminance of the LED luminaire. The photometer should be placed at a distance of one meter from the luminaire, and the luminance should be measured in lux (lx).

Benefits of Accurately Measuring LED Luminance with Photometers

Accurately measuring LED luminance with photometers is important for a variety of reasons. First, it ensures that the LED luminaire is providing the desired level of illumination. This is especially important in commercial and industrial settings, where the correct level of illumination is essential for safety and productivity. Additionally, accurately measuring LED luminance with photometers can help to identify any potential problems with the luminaire, such as incorrect wiring or faulty components.
