PROBLEM TO BE SOLVED: To provide a lighting system capable of improving mounting workability of a light source.SOLUTION: A bulb type lighting system 100 includes a light source 60 for which a light emitting part is loaded on a substrate 61, a heat sink 30 for radiating heat from the light source 60, and a light source holding body 40 mounted on the heat sink 30 for holding the light source 60 on the heat sink 30. The light source holding body 40 includes a fitting hole 41 for positioning the light source 60 and taking out light from the light source 60 by being fitted with the light source 60, and a projection part 42 provided on a part of a peripheral edge of the fitting hole 41, for arranging a peripheral edge part of the substrate 61 where the light emitting part is not loaded between the heat sink 30 and the projection part 42. |
