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 lamp device includes a main body, a light-emitting module, a lighting device and a support member. The main body includes an opening and a heat radiating part provided at an opposite side of the opening. The support member is thermally coupled to the light-emitting module and the heat radiating part. The support member holds the light-emitting module in the main body to cause the light-emitting module to be positioned in a direction closer to the opening than the lighting device.

Lamp device and luminaire

An LED module substrate includes a substrate main body, an LED mounted on one plane of the substrate main body, and a contact mounted at an edge of the one plane of the substrate main body and electrically connected to the LED. A cover section covers the LED module substrate in which the contact and the thermal radiation sheet are exposed. A lamp is attached to a socket. The socket includes a terminal electrically connected to the contact by the attachment of the lamp. A luminaire main body includes a thermal radiator including a contact surface and a recess. The lamp attached to the socket is brought into contact with and thermally connected to the contact surface. The recess is provided in a position opposed to the terminal of the socket.

Socket and lamp engagement configurations for a luminaire

A lighting circuit substrate is arranged in a cap so that one surface of a lighting circuit substrate and a flat portion of a cap projection are arranged so as to face each other. Also, lighting circuit components are mounted on the one surface of the lighting circuit substrate, and the lighting circuit components are arranged within the cap projection. Arrangement is such that a clearance between the lighting circuit substrate and the flat portion of the cap projection becomes larger than the height of a component whose projecting dimension from the lighting circuit substrate is the largest from among the lighting circuit components.

Lamp unit 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.
