Abstract (en)
[origin: EP2473007A1] The LED module (1) has identical LEDs (2-4). The LED (3) is operated with constant current and the LED (4) is operated with constant voltage simultaneously such that the common emitted luminous flux of the LEDs (3,4) over a predetermined temperature range is constant. Independent claims are included for the following: (1) method for passive light flux stabilization of led module; (2) LED lamp; and (3) LED system.
