Claims

[Claims for Utility Model Registration] An optical transmission head installed in an optical space propagation data transmission device for emitting light into space, which is formed symmetrically around a center line, and the center line is vertical. A conical mirror provided at a constant height parallel to the line; and one or more mirrors disposed on the top side of the conical mirror and emitting light toward the outer peripheral surface of the conical mirror. A light transmitting head for an optical space propagation data transmission device, comprising: a light emitting element, and the light emitted from the light emitting element is reflected from the conical mirror to a space in the entire horizontal direction. .
