Introduction
LED testing is an important part of the lighting industry, as it helps to ensure that LED luminaires are safe and efficient. Two of the most commonly used methods for LED testing are the goniophotometer and the integrating sphere. Both of these methods have their own advantages and disadvantages, and it is important to understand the differences between them in order to choose the best method for a particular application. In this article, we will investigate the differences between goniophotometer and integrating sphere for LED testing.
goniophotometer
A goniophotometer is a device that is used to measure the light output of a light source. It consists of a rotating arm with a light detector at one end, and a light source at the other. The light detector measures the light output of the source at different angles, and the data is used to calculate the total light output of the source. goniophotometers are typically used to measure the light output of LED luminaires, as they are able to accurately measure the light output at different angles.
Integrating Sphere
An integrating sphere is a device that is used to measure the total light output of a light source. It consists of a hollow sphere with a light detector at one end, and a light source at the other. The light detector measures the total light output of the source, and the data is used to calculate the total light output of the source. Integrating spheres are typically used to measure the total light output of LED luminaires, as they are able to accurately measure the total light output of the source.
Differences between Goniophotometer and Integrating Sphere
The main difference between a goniophotometer and an integrating sphere is the way in which they measure the light output of a light source. A goniophotometer measures the light output at different angles, while an integrating sphere measures the total light output of the source. This means that a goniophotometer is better suited for measuring the directional light output of a source, while an integrating sphere is better suited for measuring the total light output of a source.
Another difference between the two devices is the accuracy of the measurements. goniophotometers are typically more accurate than integrating spheres, as they are able to measure the light output at different angles. This means that goniophotometers are better suited for applications where accuracy is important, such as in the testing of LED luminaires.
Conclusion
In conclusion, goniophotometers and integrating spheres are two of the most commonly used methods for LED testing. Goniophotometers are better suited for measuring the directional light output of a source, while integrating spheres are better suited for measuring the total light output of a source. Goniophotometers are typically more accurate than integrating spheres, making them better suited for applications where accuracy is important. Understanding the differences between goniophotometer and integrating sphere for LED testing is important in order to choose the best method for a particular application.
