Light emitting structure and mount
In a method according to embodiments of the invention, a light emitting structure comprising a plurality of light emitting diodes (LEDs) is provided. Each LED includes a p-contact and n-contact. A first mount and a second mount are provided. Each mount includes anode pads and cathode pads. The anode pads are aligned with the p-contacts and the cathode pads are aligned with the n-contacts. The method further includes mounting the light emitting structure on one of the first and second mounts. An electrical connection on the first mount between the plurality of LEDs differs from an electrical connection on the second mount between the plurality of LEDs. The first mount is operated at a different voltage than the second mount.
