LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a lighting device capable of suppressing mutual thermal effect between a light-emitting element and a power supply circuit which are mounted on a single substrate.SOLUTION: A lighting device 10 includes a light source unit 12 and a housing 11. The light source unit 12 includes: a substrate 20 on one end side of which a light-emitting element mounting region 23a is provided and on another end side of which a power supply circuit mounting region 23b is provided; a light emitting element 21 which is mounted on the light-emitting element mounting region 23a of the substrate 20; and a power supply circuit 22 which is mounted on the power supply circuit mounting region 23b of the substrate 20. The housing 11 is provided with the substrate 20 on a bottom surface thereof, includes a space 34 formed with the substrate 20 inside thereof, and includes a partition part 43 projecting into the space 34 corresponding to a position between the light-emitting element mounting region 23a and the power supply circuit mounting region 23b of the substrate 20 so as to partition the space part 34.SELECTED DRAWING: Figure 1
