Proposed is a light-emitting apparatus, comprising a semiconductor light emitting deviceand a transparent ceramic bodycomprising a wavelength converting material positioned in light receiving relationship to the semiconductor device. The light-emitting apparatus is characterized in that the side surfacesof the ceramic bodyare at an oblique anglerelative its bottom surface. This is especially advantageous to unlock the wave-guide modes inside the body. Consequently the total flux emitted from the light-emitting apparatuscan be enhanced considerably. Alternatively, the brightness of the top surfaceof the ceramic bodycan be enhanced considerably.
