Both ends of a lamp body are mounted on sockets of an apparatus body and a feeding unit configured to feed power to LEDs is provided on the back side facing the apparatus body of the lamp body.

Tube lamp and luminaire

A luminaire capable of contacting a lamp device to a luminaire main body is provided. A luminaire includes a luminaire main body that includes an abutment portion in which heat is transferred and a mounting receiving portion, a socket device that includes a socket main body having an opening portion, an engagement receiving portion which is provided in the opening portion, a mounting member which is fixed to the mounting receiving portion, a receiving portion which receives an elastic member generating an elastic force between the socket main body and the mounting member, and a connection portion which is electrically connected to an external power source, and is mounted so as to move in the elasticity direction of the elastic member with respect to the luminaire main body by the mounting member, and a lamp device that includes a contact portion which contacts the abutment portion, an engagement portion which engages with the engagement receiving portion, and a lamp side connection portion which is electrically connected to the connection portion, wherein the abutment portion of the luminaire main body and the contact portion of the lamp device closely contact with each other by the elastic force of the elastic member according to an operation in which the engagement portion of the lamp device and the engagement receiving portion of the socket device are engaged with each other.

Luminaire

Provided are a cap, a socket device, and a luminary which reduce the influence of noise. A lamp with the cap includes a lamp main body having engaging means mounted so as to be attachable to and detachable from a socket device; a light emitting-portion; a control device that controls the light-emitting portion; a cap member for a power source situated adjacent to one side with the engaging means interposed therebetween is disposed in a circular track of the lamp main body and connected to the control device; a cap member for signaling situated adjacent to the other side with the engaging means interposed therebetween is disposed in the circular track of the lamp main body and connected to the control device; and a thermal conductor that comes into contact with a thermal radiator when mounted on the socket device.

Cap, socket device, and luminaire

There is provided a lighting fixturecapable of efficiently radiating heat of a lamp deviceattached to a socket device. By attaching the lamp deviceto the socket device, a cap portionof the lamp device is brought into contact with a fixture body, and pressed against and brought into contact with the fixture bodyby an elastic body. Heat generated by lighting of LEDsof the lamp deviceis conducted from the cap portionto the fixture bodyand efficiently radiated.

Lighting fixture

A lighting fixture capable of efficiently radiating heat of a lamp device may be configured to be attached to a socket device. In some examples, by attaching the lamp device to the socket device, a cap portion of the lamp device is brought into contact with a fixture body, and pressed against and brought into close contact with the fixture body by an elastic body. Heat generated by lighting of LEDs of the lamp device is conducted from the cap portion to the fixture body and efficiently radiated.
