Introduction to Accurately Measuring Lumen Output of LEDs
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 lumen output of LEDs in order to ensure that they are providing the desired amount of light. This article will discuss the various methods of accurately measuring lumen output of LEDs, as well as the importance of doing so.
Methods of Measuring Lumen Output of LEDs
The most common method of measuring lumen output of LEDs is with a lux meter. A lux meter is a device that measures the amount of light that is emitted from a source. It is important to note that lux meters measure the amount of light that is visible to the human eye, and not the total amount of light that is emitted from the source. This means that the lux meter will not measure the infrared or ultraviolet light that is emitted from the LED.
Another method of measuring lumen output of LEDs is with a spectrometer. A spectrometer measures the intensity of light at different wavelengths. This allows for a more accurate measurement of the lumen output of LEDs, as it takes into account the infrared and ultraviolet light that is emitted from the LED.
Importance of Accurately Measuring Lumen Output of LEDs
Accurately measuring the lumen output of LEDs is important for a number of reasons. First, it allows for the proper selection of LEDs for a given application. If the lumen output of the LEDs is not accurately measured, then it is possible that the LEDs may not provide the desired amount of light.
Second, accurately measuring the lumen output of LEDs allows for the proper selection of LED drivers. LED drivers are used to control the amount of current that is supplied to the LEDs. If the lumen output of the LEDs is not accurately measured, then it is possible that the LED drivers may not be able to provide the desired amount of current to the LEDs.
Finally, accurately measuring the lumen output of LEDs allows for the proper selection of LED fixtures. LED fixtures are used to house the LEDs and provide a means of mounting them. If the lumen output of the LEDs is not accurately measured, then it is possible that the LED fixtures may not be able to provide the desired amount of light.
