PROBLEM TO BE SOLVED: To provide LED bulbs 10, 20, 30 in which a large number of LED chips 12, 22, 32 can be built as light sources, and that can mitigate glare.SOLUTION: Module substrates 13 are aligned to stand on a pedestal 11b of an upper end face 11a of a heat radiation body 11, and a large number of LED chips 12 are provided on the heat radiation body 11 as light sources of an LED bulb 10, so as to increase a light amount of the LED bulb 10. By covering a module substrate group with a single light diffusion member 17 and diffusing light of the LED chips 12, even when the light sources comprise the large number of LED chips 12 serving as point light sources, light is made to be emitted like the LED bulb 10 as if it includes one large light source emitting soft light. |
