PROBLEM TO BE SOLVED: To provide a lighting device that can be controlled to cause rain water fallen onto the lighting device to flow toward a fixing part of a supporting column.SOLUTION: When a fitting part 30A is attached to a supporting column 11, a top surface 24 of a lighting body 20A is inclined to cause its opposite side of the supporting column 11 to become higher in respect to a horizontal plane HL. The top surface 24 is formed continuously by a prescribed length from a side opposite to the fitting part 30A to the fitting part 30A with a substantial concave sectional shape. Due to this fact, rain and snow fallen on the top surface 24 of the lighting body 20A flows to the lower side supporting column 11. In addition, even if ice columns are generated with fallen rain and snow, it is generated at the supporting column 11, so that it is possible to light up below against light produced from the lighting body 20A. |
