The present invention relates to an LED tunnel lighting device comprising: a main body part including a circuit board on which multiple LED chips are arranged and a cylindrical main body housing having a heat radiation unit to emit heat generated from the LED chips to the outside inside thereof; a converter part including a converter to convert power supplied to the circuit board, and a cylindrical converter housing in which the converter is installed and which is combined to one side of the main body housing, wherein the converter is installed to be separable from the circuit board and the heat radiation unit, and can be replaced and inspected through an opening/closing unit formed at one side of the converter housing. By forming the converter part with a heat source, the converter to be separated from the main body part in which a main heat source, the LED chips are arranged, that is, by dispersing the heat sources, the efficiency of heat radiation can be maximized. In addition, workability can be improved since the converter can be inspected and replaced by opening and closing only the converter part. |
