    • The present invention relates to a controller (30) for controlling the light-output of two light-emitting devices (10, 20). The two light-emitting devices are adapted to provide a McCandless effect on an illuminated object (40). The controller (30) comprises a first user interface for a user to set a first color (11) to be output by a first light-emitting device (10) and second user interface for a user to set a desired mixed color (81) of a common area (80) being illuminated by both light-emitting devices (10, 20). The controller (30) further comprises a processing circuitry for determining first lighting parameters resulting in said first color (11) when provided to the first light-emitting device (10), and for determining second lighting parameters resulting in a second color (21) when provided to a second light-emitting device (20). A mix of the first color (11) and the second color (21) provides the mixed color (81). The first color (11) and the mixed color (81) are represented in a color space chromaticity diagram such that they define a line and the second color (21) is determined such that it is located on said line in the color space chromaticity diagram on an opposite side of the desired mixed color (81) relative to the first color (11). Further, the second color (21) is determined by the processing circuitry such that the desired mixed color (81) is achieved when the first (11) and the second (21) colors are mixed.

    • A LED light source comprises—a full bridge rectifier equipped with a first input terminal and a second input terminal for coupling to output terminals of the phase cut dimmer, —a series arrangement comprising N LED loads, a first and second end of said series arrangement being coupled to a first output terminal and a second output terminal of the full bridge rectifier respectively, —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, said control means controlling the current through the LED loads at zero when the output voltage of the phase cut dimmer equals zero and controlling the current through the LED loads at a value that is independent from the phase angle of the phase cut dimmer when the output voltage of the phase cut dimmer differs from zero Volt. In order to make the LED light source compatible with a phase cut dimmer, the LED light source is further equipped with—a switchable bleeder current source coupled between the first and second output terminal of the full bridge rectifier, —a latch coupled between the first and second output terminals of the full rectifier bridge and comprising a series arrangement of a resistor and a capacitor to prevent the current through the dimmer from crossing zero after a leading edge generated by the phase cut dimmer, in case the phase cut dimmer is a leading edge phase cut dimmer, —a unidirectional element arranged in series with the capacitor for preventing discharging of the capacitor via the LED loads or the adjustable bleeder current source, and—a clamp circuit coupled to the capacitor and comprising a current source for discharging the capacitor and providing a low ohmic path for the dimmer current when the dimmer is off.
