PROBLEM TO BE SOLVED: To provide a lighting system capable of effectively improving uneven brightness or uneven color, easily coping with the change of specifications such as increase or decrease in the number of light-emitting devices or change in arrangement intervals, causing no increase in production cost. SOLUTION: A plurality of light emitting diodes 4R, 4G, 4B are installed on a substrate 3, a plurality of first globular lenses 7 are arranged on the light emitting diodes 4R, 4G, 4B in a state contacting with the shoulder parts of adjacent light emitting diodes 4R, 4G, 4B, and a plurality of second globular lenses 8 are arranged on the first globular lenses 7 in a state contacting with the upper parts of adjacent first globular lenses 7. |
