Abstract
A light-emitting device includes a circuit board, a light-emitting element, a light-condensing element, and a glue. The circuit board has through holes, a first surface, and a second surface. The through hole has a first pathway and a second pathway. The first pathway extends from the first surface into the circuit board. The second pathway extends from the second surface into the circuit board and communicates with the first pathway. An accommodating space of the second pathway is greater than that of the first pathway. The light-emitting element is disposed on and electrically connected to the first surface. The light-condensing element has positioning posts. A portion of the light-condensing element is disposed on the light-emitting element. The positioning post passes through the first pathway and is located inside the second pathway. The glue is disposed in the second pathway for fixing the positioning posts in the through hole.
