First Claim
1. An illumination device comprising one or more emitter modules, wherein each emitter module comprises:
- a plurality of light emitting diodes (LEDs) configured for producing illumination for the illumination device;
one or more photodetectors configured for detecting the illumination produced by the plurality of LEDs;
a multiple layer substrate upon which the plurality of LEDs and the one or more photodetectors are mounted;
a primary optics structure coupled to a top surface of the multiple layer substrate for encapsulating the plurality of LEDs and the one or more photodetectors within the primary optics structure; and
a heat sink coupled to a bottom surface of the multiple layer substrate; and
wherein the multiple layer substrate comprises;
a first routing layer coupled to electrical contacts of the plurality of LEDs and the one or more photodetectors;
a first dielectric layer coupled to a bottom surface the first routing layer and configured for providing electrical isolation between the electrical contacts and the heat sink;
a second routing layer coupled to a bottom surface of the first dielectric layer and configured for routing signals between the first routing layer and external electrical contacts arranged outside of the primary optics structure; and
a second dielectric layer coupled to a bottom surface of the second routing layer and configured for providing a relatively high thermal impedance in a lateral direction, and a relatively low thermal impedance in a vertical direction.
