Illumination device including a light-emitting module fastened to mount member with a constant orientation
First Claim
1. 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, whereinthe 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, andthe 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.

Abstract
A mount member (5) has a contact surface (27a) touching the bottom surface of an LED module (3) and protrusions (5a) protruding from the periphery of the contact surface (27a) in the thickness direction of the LED module (3) and regulating sliding motions thereof. A fixing member (6) made of a resilient, plate-like member comprises an opposing pair of flat portions (43) near the contact surface (27a) of the mount member (5) and flat tabs (44) projecting from the flat portions (43) toward the contact surface (27a) touching the upper surface of a substrate (17). The flat portions (43) of the fixing member (6) are fastened to be lower than the top surface of the substrate (17) of the LED module (3). Thus, elastically deformed areas extending from the fastened parts of the flat portions (43) through the flat tabs (44) press the substrate (17) into the mount member (5).
