Introduction to LED Testing: Measuring Luminance with a colorimeter
LEDs are becoming increasingly popular in lighting applications due to their energy efficiency and long life. However, it is important to ensure that the LED luminaires are performing as expected. One way to do this is to measure the luminance of the LEDs with a colorimeter. A colorimeter is a device that measures the amount of light emitted from a light source. It is used to measure the color and brightness of a light source, and can be used to test LED luminaires.
How to Measure Luminance with a Colorimeter
Measuring luminance with a colorimeter is a relatively simple process. First, the colorimeter must be calibrated to the LED luminaire being tested. This is done by setting the colorimeter to the same color temperature as the LED luminaire. Once the colorimeter is calibrated, it can be used to measure the luminance of the LED luminaire. The colorimeter will measure the amount of light emitted from the LED luminaire and display the results in lux (lumens per square meter).
Benefits of Measuring Luminance with a Colorimeter
Measuring luminance with a colorimeter has several benefits. First, it is a quick and easy way to measure the luminance of an LED luminaire. This can be especially useful for testing large numbers of LED luminaires, as it eliminates the need to manually measure each luminaire. Additionally, measuring luminance with a colorimeter is more accurate than manual measurements, as it takes into account the color temperature of the LED luminaire.
Conclusion
Measuring luminance with a colorimeter is a quick and easy way to test LED luminaires. It is more accurate than manual measurements, and can be used to test large numbers of LED luminaires. Colorimeters are relatively inexpensive and easy to use, making them a great tool for testing LED luminaires.
