Abstract (en)
[origin: EP2291057A2] The light emitting diode-lamp has a light emitting diode and an optical functional element in the light channel between the source and outlet port of the light. The light emitting diode has the characteristics of an integrating sphere and thus the total produced luminous flux at the outer wall is measured by the small light portion by a light sensor.
