PROBLEM TO BE SOLVED: To reduce cost for a lamp which displays information and alerts the attention on the road, on the sea and the like by radiating light from a light source such as a light-emitting diode.SOLUTION: In a lamp 1a, light-emitting diodes 8 are arranged on a plurality of substrates 7 radially arranged at an appropriate angle so that it may be recognized from all directions of 360 degrees. Each of the substrates 7 comprises a notched part 14 on which the light-emitting diode 8 is arranged so that it is recognized from front and back sides of the substrate 7. From the notched part 14, light from the light-emitting diodes 8 arranged on the notched part 14 of the adjacent substrates 7 may be recognized. |
