According to one embodiment, a lamp apparatus includes a light-emitting module, housing, and a lighting circuit. The light-emitting module includes a light-emitting element. The housing opens in the direction of irradiation of a light beam and having a cap on a side opposite from the direction of irradiation of the light beam. The cap is provided with a light-emitting module mounting portion projecting in the direction of irradiation of the light beam and the light-emitting module is mounted on the light-emitting module mounting portion. The lighting circuit is accommodated in the housing.

Luminaire and lamp apparatus housing

According to one embodiment, a light-emitting device includes a substrate, a first light-emitting element group, a second light-emitting element group, and a terminal group. The first light-emitting element group includes plural first light-emitting elements mounted on the substrate. The second light-emitting element group is mounted on the substrate alongside the first light-emitting element group and includes plural second light-emitting elements. The terminal group includes plural terminals electrically connected to the first light-emitting element group and the second light-emitting element group, and is arranged on a side of the first light-emitting element group opposite to a side thereof facing the second light-emitting element group in a first direction in which the first light-emitting element group and the second light-emitting element group on the substrate are arranged side by side.

Light-emitting device, method for assembling same and luminaire

According to one embodiment, a lamp device includes a light-emitting module including a semiconductor light-emitting element, a lighting circuit to light the semiconductor light-emitting element, and a housing to house the light-emitting module and the lighting circuit. The housing includes a case including a holder part to hold the light-emitting module, and a cap member fixed to the case by a fixing unit. The light-emitting module is sandwiched and fixed between the holder part and the cap member.

Lamp device and luminaire

According to one embodiment, a lamp unit includes a light-emitting module, a lighting circuit, and a housing. The light-emitting module includes a light emitting portion having a semiconductor light-emitting element. The lighting circuit lights the semiconductor light-emitting element. The housing includes a case opening in the direction of irradiation of light, and a base on a side of the case opposite from the direction of radiation of the light. The lighting circuit is accommodated in the case, and the light-emitting module is mounted on the base at a position closer to the base with respect to the position of the lighting circuit.

Lamp unit and lighting fixture

According to one embodiment, a light emitting device includes: a substrate a back face side of which is disposed on a mounting member; a plurality of light emitting elements mounted on a surface side of the substrate; and a power supply terminal provided on the surface side of the substrate and electrically connected to the light emitting elements. The power supply terminal is connected to electrical connecting units by elastic pressing force directed from the surface side of the substrate to the mounting member side. A mechanical fixing unit has a pressing portion brought into contact with the surface side of the substrate. The mechanical fixing units fix the substrate to the mounting member with use of elastic pressing force of the pressing portions directed from the surface side of the substrate to the mounting member side.
