MULTICHANNEL LED MODULE WITH WHITE LEDS OF DIFFERENT COLOR COORDINATES

摘要

The invention relates to an LED module having at least one first group of serially connected dye-converted white LEDs and a second group of serially connected dye-converted white LEDs. The first group and the second group of LEDs are connected together in parallel such that the groups can be controlled independently of each other by one or more drive circuits, and the nominal color temperature of the LEDs of the first group differs from the nominal color temperature of the LEDs of the second group. Each group of LEDs has at least two sub-groups comprising LEDs, said sub-groups differing with respect to the color location, and the groups and the sub-groups of LEDs are arranged on a substrate in a periodically repeating pattern at least in one direction of extension.
