Introduction to LED Testing with portable spectroradiometers
Light-emitting diode (LED) luminaires are becoming increasingly popular in the lighting industry due to their energy efficiency and long life. However, it is important to ensure that LED luminaires are tested to ensure they meet the required standards. portable spectroradiometers are a great tool for testing LED luminaires, as they provide accurate and reliable measurements of the light output of the luminaire. This article provides a comprehensive guide to LED testing with portable spectroradiometers, including an overview of the testing process, the types of measurements that can be taken, and the benefits of using a portable spectroradiometer.
Overview of LED Testing with Portable spectroradiometers
LED testing with portable spectroradiometers involves measuring the light output of the luminaire in order to ensure it meets the required standards. The measurements taken include the total luminous flux, the color temperature, the color rendering index (CRI), and the spectral power distribution (SPD). These measurements are taken using a portable spectroradiometer, which is a device that measures the light output of a luminaire in terms of its wavelength and intensity.
The testing process begins by setting up the Spectroradiometer and positioning it in the correct position relative to the luminaire. The spectroradiometer is then used to take the required measurements, which are then compared to the required standards. If the measurements meet the required standards, the luminaire is deemed to be compliant.
Types of Measurements Taken with Portable Spectroradiometers
When testing LED luminaires with a portable spectroradiometer, there are several types of measurements that can be taken. The most common measurements are the total luminous flux, the color temperature, the color rendering index (CRI), and the spectral power distribution (SPD).
The total luminous flux is a measure of the total amount of light emitted by the luminaire. The color temperature is a measure of the color of the light emitted by the luminaire, and is measured in Kelvin (K). The color rendering index (CRI) is a measure of how accurately the luminaire renders colors, and is measured on a scale of 0 to 100. The spectral power distribution (SPD) is a measure of the intensity of the light emitted by the luminaire at different wavelengths.
Benefits of Using a Portable Spectroradiometer for LED Testing
Using a portable spectroradiometer for LED testing has several benefits. Firstly, it is a fast and accurate way to measure the light output of a luminaire. Secondly, it is a non-destructive testing method, meaning that the luminaire does not need to be dismantled or damaged in order to take the measurements. Finally, it is a cost-effective testing method, as the spectroradiometer can be used multiple times for different luminaires.
