Abstract
A lighting circuit comprises a first rectifying diode (D), a second rectifying diode (D), a third rectifying diode (D), a fourth rectifying diode (D), a first group of LEDs (LED, . . . , LED), a second group of LEDs (LED, . . . , LED), a third group of LEDs (LED, . . . , LED), and a fourth group of LEDs (LED, . . . , LED). The first group of LEDs (LED, . . . , LED) is connected between the anode and the cathode of the first rectifying diode (D); the second group of LEDs (LED, . . . , LED) is connected between the anode and the cathode of the second rectifying diode (D); the third group of LEDs (LED, . . . , LED) is connected between the anode and the cathode of the third rectifying diode (D); the fourth group of LEDs (LED, . . . , LED) is connected between the anode and the cathode of the fourth rectifying diode (D).
