Light-emitting device with reflective ceramic substrate

A light-emitting device comprising:

• a substrate comprising a reflective material infused throughout the substrate;
• a carrier having a metallic surface and being coupled directly to the substrate;
• a light-emitting diode disposed on the substrate and configured to receive power from a power source;
• at least one light-converting material layer configured to surround sides of the light-emitting diode, wherein the at least one light-converting material layer comprises a layer formed of phosphor;
• and
• an electrical insulator disposed above the substrate separate from the at least one light-converting material layer, wherein the electrical insulator is configured to electrically insulate the power source from the substrate and the carrier.

A lighting system comprising:

• a substrate comprising a first material and a reflective material infused throughout the substrate in the first material;
• a carrier having a metallic surface and a die attach material that secures the substrate directly to the carrier;
• a plurality of light-emitting diodes connected in series and disposed on the substrate, with the plurality of light-emitting diodes being configured to receive power from a power source;
• a plurality of parallel light-converting material layers configured to surround three sides of a light-emitting diode of the plurality of light emitting diodes, respectively;
• and
• an electrical insulator disposed above the substrate separate from the plurality of parallel light-converting material layers, wherein the electrical insulator is configured to electrically insulate the power source from the substrate and the carrier.
