What Can You Measure?
- Quality control of incoming LEDs delivered by various suppliers
- Measurement of fiber optic sources like endoscopes and other
- Calibration of lighting fixtures made of many LEDs
- Checking the influence of dimming
- Testing diffusers or optics installed on LEDs
- Monitoring changes of spectra, color or luminous flux
When purchasing specific groups of LEDs from your supplier you can quickly check if they met your expectation regarding the luminous flux [lm] color coordinates [x,y] or color temperature CCT [K]. Using the Opti Sphere 48 integrating sphere with a spectroradiometer of your choice you may organize and simplify incoming quality control.
Development Critical Metrics
During the development of new LED modules and fixtures you can immediately check the influence of LED drivers, new PCB boards and other components which influence lighting properties of your products. Measuring LEDs before installing them on PCB helps to improve your products and optimizes prototyping.
Other standard measurement quantities:
- Lumen – luminous flux
- CRI – color rendering index according to the CIE
- CCT – the color temperature according to standard CIE
- Color – the chromatic coordinates of the CIE 1931 and CIE 1964
- Fidelity and Gamut – method for evaluating light source color rendition according to TM-30 IES standard
- PAR/PPF – photosynthetic active radiation measurements for horticulture
- mWatt – radiation energy
