Abstract:
1. A measurement device for measurement of characteristic parameters of at least one assembly of at least one light emitting diode (LED), comprising a measurement circuit for each assembly, wherein said measurement circuit comprises: a single measurement output to provide electrical values which are representative of at least two characteristic parameters of said at least one assembly; a first circuit configuration, which is designed to provide the measurement output with a value which is representative of a first characteristic parameter of a first operational characteristic of said at least one LED; a second circuit configuration, which is designed to provide the measurement output with a value which is representative of a second characteristic parameter of a second operational characteristic of said at least one LED, wherein said second operational characteristic is different from said first operational characteristic; and means for switching between said first circuit configuration and said second circuit configuration; wherein said first operational characteristic is an electrical value associated with said at least one LED and said second operational characteristic is a temperature associated with said at least one LED.
