A lighting device includes: a circuit substrate which has a light emitting element on a side thereof; a substrate housing separated from the other side facing the one side of the support substrate; and a distance control part formed between the circuit substrate and the substrate housing, controlling a separation distance between the circuit substrate and the substrate housing in accordance to the movement of the circuit substrate. The distance control part allows the circuit substrate to be fixated to the substrate housing by a fixing unit formed on the circuit substrate and the substrate housing. |
