Abstract (en)
Disclosed is a LED module (4), comprising input terminals (41) connectable to an LED driver (3); a plurality of LED lighting means (42, 43) having different color temperatures; an auxiliary load (44A, 44B, 44C) connected between the input terminals (41) and the plurality of LED lighting means (42, 43); and one or more first switches (45A; 45B, 45C) configured to select, in dependence of one or more first PWM control signals (46A; 46B, 46C), one of the plurality of LED lighting means (42, 43) for feeding by the LED driver (3). This provides a smaller and less expensive tunable white LED module.
