Non-angle-measuring solutions for iridescence color use imaging colorimeters or luminance meters to measure light sources by far field measurement methods. In far-field distribution measurements, the CXS imaging system can be mounted on a tripod and facing the horizontal plane to measure the light cast on a wall or through a diffuser. This allows the imaging system to collect illuminance distribution data and calculate the luminous intensity of the light source from a single measurement. This measurement method can be applied to a specified measurement space in the laboratory or on the production line. The measured values include luminous intensity (cd), which is the luminous flux (lm) in a given direction. The far-field measurement system measures the pattern of the light beam projected by the light source, so the size of the fixture itself (for example, the LED strip) does not affect the measurement data as it does in the near-field measurement scenario. The non-angle-measuring system generates the IES file and bitmap file of the lighting design (captured by the imaging system).
Features of far-field measurement system:
Use only imaging colorimeters or luminance meters
Measure the illumination distribution (beam pattern) of any light source (the size of the light source has no effect on the measurement of the beam pattern)
The complete characteristics of the output light source are measured at a single time
It can be used as quality assurance in mass production operation
Light can be projected onto a wall or screen to measure light (light source reflection)
Measurement of light by diffuser (light source propagation)
