Our lighting laboratory offers you the latest lighting measurement techniques according to the CIE requirements. The measurement devices especially designed for the measurement of LEDs.
A verification of data sheets for the measurements of LEDs is in the pulse mode possible. Furthermore LEDs from different producers can be compared.
Measurement of UV (350nm), over visible, to IR (1100nm) LEDs.
The following parameters for LEDs can be measured and evaluated by us:
- Luminous flux
Measured in lumen (lm), determines the brightness of a light source in a 3-dimensioned room.
- Luminous intensity
Luminous flux/dihedral angle, measured in a candela (cd), indicates how bright a light source illuminates in a certain direction.
Luminous flux/Area, measured in LUX (lx) determines how bright an area is illuminated.
Color rendering index describing the quality of color reproduction of light sources of the same correlated color temperature.
- Colour temperature
CCT / Measured in Kelvin, gives the color impression of the light again from cold white to warm white
- Chromaticity coordinate
x, y coordinates determine the position of the color temperature in the CIE -XYZ color space
The wavelengths of visible light, lies between 380nm and 780nm.
- Viewing angle
In degrees, describes the angle at which the light leaves the light source, usually defining the emission angle as FWHM
- Beam type
Is the directional release of the light of a light
Weighted distribution of light over the wavelength range of the total electromagnetic radiation
