Patent ID: 8362681

Claim:
A semiconductor light emitting apparatus comprising: an elongated hollow wavelength conversion tube that includes first and second opposing ends and that comprises an elongated wavelength conversion tube wall having wavelength conversion material; a first semiconductor light emitting device adjacent the first end that is oriented to emit light inside the elongated hollow wavelength conversion tube to impinge upon the elongated wavelength conversion tube wall and the wavelength conversion material; a second semiconductor light emitting device adjacent the second end that is oriented to emit light inside the elongated hollow wavelength conversion tube to impinge upon the elongated wavelength conversion tube wall and the wavelength conversion material; first and second mounting substrates; and first and second domes on the respective first and second mounting substrates; wherein the respective first and second semiconductor light emitting devices are located between the respective first and second mounting substrates and the respective first and second domes; and wherein the respective first and second domes extend at least partially into the respective first and second ends of the elongated hollow wavelength conversion tube and the respective first and second mounting substrates extend at least partially outside the elongated hollow wavelength conversion tube at the respective first and second ends.
