Abstract
According to one embodiment, a thermal radiator of a lamp device includes a light-emitting module connection part to which a light-emitting module is thermally conductively connected. An attachment base is arranged around the light-emitting module connection part. The attachment base is made of an insulating material, and supports the light-emitting module connected to the light-emitting module connection part. The light-emitting module connection part protrudes from the attachment base.
Claims18
A lamp device comprising:
- a housing including an opening part at one end side, a closing part at the other end side and an insertion part formed at a center of the closing part;
- a light-emitting module arranged in the housing so as to emit light from the opening part;
- a lighting device arranged to be closer to the closing part side than the light-emitting module in the housing and including a circuit board arranged around the insertion part;
- a thermal radiator including a support part inserted through the insertion part, a light-emitting module connection part which is provided at one end side of the support part and to which the light-emitting module is thermally conductively connected, and a thermal radiator provided at the other end side of the support part and including an external thermal radiation part;
- and
- an attachment base which is made of an insulating material, is arranged around the light-emitting module connection part, is provided with an attachment surface facing the light-emitting module at one end side, and supports the light-emitting module connected to the light-emitting module connection part which protrudes from the attachment surface.
