Light emitting device

A light-emitting device comprises a substrate, a plurality of light-emitting elements and a light guide structure. The light-emitting element is arranged on the substrate. The light guide structure is arranged on the substrate, the light guide structure separates the light-emitting element and continuously surrounds the light-emitting element, the light guide structure and the light-emitting element are separated from each other, light emitted by the light-emitting element can enter the light guide structure to enable the light guide structure to emit light, and the light guide structure is made of materials with the refractive index ranging from 1.1 to 3. According to the light guide structure, the light-emitting device can still have good brightness uniformity under the conditions that the number of the light-emitting diodes is greatly reduced and a thin diffusion structure is adopted. 一种发光装置，包括基板、多个发光元件及导光结构。发光元件设置于基板上。导光结构设置于基板上，导光结构分隔发光元件并连续围绕发光元件，导光结构与发光元件彼此分离，发光元件发出的光能进入到导光结构内而使导光结构发光，导光结构由折射率为1.1至3的材料
