  • Optoelectronic semiconductor component capable of centralizing emitted light
    Patent number: 7855392
    Abstract: An optoelectronic semiconductor component includes a light-emitting chip for emitting light, and a reflective substrate. A plurality of linear indent structures is formed on the reflective substrate. The light-emitting chip is installed on the reflective substrate and located on a side of the plurality of linear indent structures. The plurality of linear indent structures is capable of reflecting the light emitted from the light-emitting chip.
