Led light source

LED light source comprising

• a first circuit input terminal and a second circuit input terminal for connection to a supply voltage source supplying an AC supply voltage with frequency f,
• a first rectifier equipped with a first input terminal coupled to the first circuit input terminal and a second input terminal coupled to the second circuit input terminal,
• a first series arrangement comprising N LED loads, a first and second end of said first series arrangement being coupled to a first output terminal a ld a second output terminal of the first rectifier respectively, wherein N is an integer
• first control means for during a period of the rectified AC supply voltage subsequently making the LED loads comprised in the first series arrangement carry a current, one by one and in dependency of the momentary amplitude of the rectified AC supply voltage when the momentary amplitude increases and for subsequently making the LED loads stop carrying a current, one by one, and in dependency of the momentary amplitude of the rectified AC supply voltage when the momentary amplitude decreases,
• a second rectifier equipped with a first input terminal coupled to the first circuit input terminal via a reactive element and a second input terminal coupled to the second circuit input terminal,
• a second series arrangement comprising M LED loads, a first and second end of said second series arrangement being coupled to a first output terminal and a second output terminal of the second rectifier respectively, wherein M is an integer, and
• a second control means for, during a period of the rectified AC voltage present between the output terminals of the second rectifier, subsequently making the LED loads comprised in the second series arrangement carry a current, one by one and in dependency of the momentary amplitude of the rectified AC voltage when the momentary amplitude increases and for subsequently making the LED loads stop carrying a current, one by one, and in dependency of the momentary amplitude of the rectified AC voltage when the momentary amplitude decreases.
