The application relates to an optical structure, a semiconductor light-emitting device and a light-emitting apparatus. The optical structure comprises a light-transmitting piece and a truncation structure. The light-transmitting piece comprises a support part and a light-emitting part which are integrally arranged. The support part is hollowly arranged, and the light-emitting part encloses one end of the support part. The truncation structure is light-opaque and has a through hole. The outer side of the truncation structure corresponds to the inner side of the support part and laterally shields all the inner sides of the support part, and one end of the through hole corresponds to the light-emitting part. The optical structure integrates the truncation structure on the inner side of the support part of the light-transmitting piece. The truncation structure shields part of the lateral light rays and truncates the light emission of the light-emitting chip, thereby improving the cutoff of the light spot projected by the semiconductor light-emitting device, making the light spot edge clearer, weakening or basically eliminating the light-dark transition phenomenon of the light spot, and improving the light spot quality.
