| 摘要 |
A radiation-emitting device comprising a side-emitting optoelectronic device having an upper surface and a heat sink in thermal conductivity with the side-emitting optoelectronic device. A reflector at least partially surrounds the side-emitting optoelectronic device. The reflector is positioned and shaped to reflect the emitted light substantially in an output direction. A reflective, non-transparent layer is disposed adjacent the upper surface of the side-emitting optoelectronic device.
