Patent ID: 8449154

Claim:
An illumination device including a light-emitting module having a substrate and a light-emitting unit mainly constituted by a light-emitting element on a central portion of a top surface of the substrate, the light-emitting module being fixed to a mount member by a pressing member, wherein the mount member has a contact surface in contact with a bottom surface of the light-emitting module mounted thereon, and a regulating portion regulating sliding motions of the light-emitting module in protruding from near the contact surface along the thickness dimension of the light-emitting module, the pressing member is made of a resilient plate-like member and comprises: flat portions disposed in areas peripheral to the contact surface of the mount member; and one or more flat tabs reaching from the flat portions toward the contact surface and coming into contact with the top surface of the substrate of the light-emitting module, and the pressing member is fastened such that the flat portions come to be positioned lower than the top surface of the substrate of the light-emitting module, thereby causing each flat tab of the pressing member to press the light-emitting module due to forces applied by elastic deformation in a region extending from a fastened area of the flat portions to the flat tab.
