Abstract
A semiconductor light emitting apparatus includes an elongated hollow wavelength conversion tube that includes an elongated wavelength conversion tube wall having wavelength conversion material, such as phosphor, dispersed therein. A semiconductor light emitting device 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 dispersed therein. The elongated hollow wavelength conversion tube may have an open end, a crimped end, a reflective end, and/or other configurations. Multiples tubes and/or multiple semiconductor light emitting devices may also be used in various configurations. Related assembling methods are also described.
