Lamp Device and Luminaire

摘要

According to one embodiment, a lamp device includes a housing, an insulating sheet, and a light-emitting module. The housing includes a thermal radiation section on the rear side opposite to the front side, which is a light emission side. A projecting section projects to the front side of the thermal radiation section. The insulating sheet includes an insert-through hole through which the projecting section is inserted. The insulating sheet is arranged on the front side of the thermal radiation section. The light-emitting module includes a substrate having a shape larger than the external shape of the projecting section and a light-emitting section formed on the front side surface of the substrate. The rear side surface of the substrate is thermally connected to the projecting section.
