A high power lighting fixture is formed from a group of LEDs 14 connected in series and mounted on a circuit board 8. A number of matching circuit boards 8 are interconnected together via connectors 12. In doing so, the individual groups series connected LEDs 14 are connected in parallel (fig 1d). A controller (20, fig 1d) is mounted on at least one of the circuit boards 8, which may receive a control signal and, based on the control signal, determine current division between the groups of LEDs 14. |
