A light guide component, a key apparatus, and an operation panel. The light guide component comprises a light incident portion (1), a light conduction portion (2), and a light emergent portion (3). The light emergent portion (3) is an annular column. The light incident portion (1) is located on the periphery of the light emergent portion (3). The light conduction portion (2) comprises a first introducing portion (21), a second introducing portion (22), a first conduction arm (23), and a second conduction arm (24). One end of the first conduction arm (23) and one end of the second conduction arm (24) are respectively connected to two sides of the light incident portion (1), and the other end of the first conduction arm (23) and the other end of the second conduction arm (24) are respectively connected to the first introducing portion (21) and the second introducing portion (22). By means of the light guide component, the light conduction path is changed multiple times in the light conduction portion (2), and uniform, soft light is evenly diffused out of the top of the light emergent portion (3). |
