The system add-on luca'lux expands the luca system by a fast and easy measurement of illuminance and respectively
of illuminance distributions.
In this connection the luminaire or optical system illuminates a diffusely scattering measuring face. Reflecting or
transmitting measuring screens are available and can be used. The software provides a comfortable assistant (calibration wizard) calibrating the system with respect to a traceable transfer standard.
The complete illuminance distribution measurement of a luminaire or, e.g. an automobile headlamp is then carried
out within only a few seconds. Predefined evaluation masks enable a complete analysis regarding the desired ECE or SAE standard.
The background colouring shows at once whether all test points lie within the prescribed area or whether some values do not meet the standard. Any further evaluation masks or test points can be defined by the user.
The system is operable within measuring distances of 5 m to 25 m. The conversion of smaller measuring distances
to the 25 m distance is easily done. When measuring tail lamps the measurement is transformed from spatial coordinates to angle space, which enables a direct evaluation of the luminous intensity as a function of the emission angle. As a matter of course, a speedy analysis regarding the respective standards is possible.
Efficiency degrees are specified by integrating arbitrary areas of the measurement to define the luminous flux.
