Embodiment
[0019] Such as figure 1 , figure 2 and image 3 As shown, a light-emitting device with dual functions of illumination and communication includes a substrate layer 1, a buffer layer 10, an n-type layer for generating electrons, a quantum well layer 12 for electron-hole recombination, a p-type layer for generating holes, and A transparent electrode layer 14 , a plurality of communication-type light-emitting chip chips 3 and a plurality of lighting-type chip chips 4 forming a ring structure are deposited on the substrate layer 1 .
[0020] During operation, the n-type layer that generates electrons provides electrons, the p-type layer that generates holes provides charges, and electrons and holes recombine in the quantum well layer 12 where electrons and holes recombine and emit light. The use of ring-shaped chip core particles makes the electron-hole recombination uniform in the quantum well layer 12 of electron-hole recombination, achieving a high recombination rate, so as t...
