PROBLEM TO BE SOLVED: To prevent a gap between LED chips from occurring on an irradiation surface in an LED light bulb having a plurality of LED chips as a light source.SOLUTION: An LED light bulb comprises: a light source having a plurality of LED chips formed on a substrate; a lens body which is arranged in a radiation direction of the light source, and in which a recess part for covering the light source part is formed; and a casing for accommodating the light source and the lens body. An inner surface of the recess part of the lens body has an inclined structure for diffusing radiation light of the LED chips, and the inclined structure is formed so that the vertical radiation light of the LED chips directly enters. |
