Abstract:
A lighting structure according to embodiments of the invention includes a semiconductor light emitting device and a flat wavelength converting element attached to the semiconductor light emitting device. The flat wavelength converting element includes a wavelength converting layer for absorbing light emitted by the semiconductor light emitting device and emitting light of a different wavelength. The flat wavelength converting element further includes a transparent layer. The wavelength converting layer is formed on the transparent layer.
