A light emitting device includes several LEDs, mounted on a shared submount,
and
coupled to circuitry formed on the submount. The LEDs can be of the III-Nitride
type. The architecture of the LEDs can be either inverted, or non-inverted. Inverted
LEDs offer improved light generation. The LEDs may emit light of the same wavelength
or different wavelengths. The circuitry can couple the LEDs in a combination of
series and parallel, and can be switchable between various configurations. Other
circuitry can include photosensitive devices for feedback and control of the intensity
of the emitted light, or an oscillator, strobing the LEDs.
