<P>PROBLEM TO BE SOLVED: To provide a lighting system for suppressing the temperature rise of a light emitting element substrate while eliminating the need for a heat sink between the light emitting element substrate and a support. <P>SOLUTION: The lighting system includes the light emitting element substrate 2 on which a light emitting element 1 is mounted, a power supply circuit board 8 on which a power supply circuit is mounted for supplying driving power to the light emitting element substrate 2, and the support 4 for supporting the light emitting element substrate 2 and the power supply circuit board 8, the light emitting element substrate 2 and the power supply circuit board 8 being isolated from each other, the support 4 between the light emitting element substrate 2 and the power supply circuit board 8 isolated from each other having a mounting hole 43 via which it is mounted on another. Between the light emitting element substrate 2 and the power supply circuit board 8, a shielding body 5 is provided for shielding heat. A component 9 to be connected to the power supply circuit board 8 or the light emitting element substrate 2 is located between the light emitting element substrate 2 and the power supply circuit board 8 and mounted on the support 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
