<P>PROBLEM TO BE SOLVED: To provide a lighting apparatus which can remove heat from a light emitting device efficiently to an apparatus body, and in which the light emitting device is easily mounted on the apparatus body. <P>SOLUTION: The lighting apparatus 12 includes the light emitting device 10 with a light emitting element 1 mounted on one surface side of a mounting substrate 2, a plurality of fixing screws 61 for fixing the mounting substrate 2 of the light emitting device 10 on the apparatus body 6, and a heat conductive sheet 7 which is in pressure-contact between the other surface of the mounting substrate 2 and the apparatus body 6. A recessed part 6a for housing the heat conductive sheet 7 is arranged on at least one of the other surface of the mounting substrate 2 and the apparatus body 6 including a region on which the light emitting element 1 mounted on the mounting substrate 2 is projected to an apparatus body 6 side in a plane view. The recessed part 6a is larger than the heat conductive sheet 7, and has a depth dimension smaller than a thickness dimension of the heat conductive sheet 7 and has a larger dimension than an elastically deforming dimension of the heat conductive sheet 7. <P>COPYRIGHT: (C)2010,JPO&INPIT |
