Beschreibung
Zusammenfassung:	A light emitting diode (LED) based illumination device include a plurality of LEDS mounted to mounting board and includes a transmissive plate disposed above the LEDs. The transmissive plate includes an amount of wavelength converting material configured to change a wavelength of an amount of light emitted by the plurality of LEDs. A base reflector structure is coupled to the LED mounting board and the transmissive plate between at least two of the LEDs. In another configuration, a dam of reflective material surrounds the LEDs and is coupled to the LED mounting board and the transmissive plate, while a dam of thermally conductive material surrounds the dam of reflective material. In another configuration, the LED mounting board has a protrusion of thermally conductive material that surrounds the LEDs and is coupled to the transmissive plate, and has a void on the side opposite the protrusion.
