  • Patent number: 10192854
    Abstract: Light emitter components and related methods are provided. In some aspects, light emitter components and related methods include a ceramic submount having a reflective surface. Light emitter components and related methods can include light emitter chips disposed over the reflective surface. Each light emitter chip can include a sapphire substrate, an epi area disposed over the sapphire substrate, and first and second electrical contacts disposed over the epi area. The first and second electrical contacts may face the reflective surface. A ratio between a combined epi area of the plurality of light emitter chips and a surface area of the reflective surface may be at least 0.4 or more, and a ratio between a combined planar surface area of the plurality of light emitter chips and a planar surface area of the reflective surface may be at least approximately 0.25 or more.
