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

A lamp apparatus includes an apparatus body including a housing having a cap at one end side, and thermal conducting fins provided on an inner surface of the housing so as to extend from the one end side along the other end side thereof and project inward of the housing, a thermal radiation plate attached to the other end side of the housing in a state in which one surface side is in contact with the thermal conducting fins, a light-emitting body attached to the other surface side of the thermal radiation plate, and a lighting circuit disposed in the housing and configured to light the light-emitting body.

Lamp apparatus and 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

According to one embodiment, a lighting apparatus includes a main body including a flat thermal conduction surface. The thermal conduction surface contacts a back surface of a board. Light-emitting devices are mounted on a front surface of the board. An optical member is opposed to a peripheral part of the board on the front surface side of the board. The optical member is fastened to the main body by fastening members, to push the peripheral part of the board against the heat conduction surface of the main body.

Lighting apparatus

A lighting apparatus is provided with a plurality of light-emitting devices, a substrate, a blind member, and a reflector. The reflector is formed with a plurality of reflective surfaces corresponding to the light-emitting devices, individually. The shielding angle at which light emitted from that one of the light-emitting devices which is located on the outermost periphery is intercepted by the reflective surface corresponding to the outermost light-emitting device is greater than shielding angles at which light emitted from the light-emitting devices located inside the outermost light-emitting device is intercepted by the reflective surfaces corresponding to the inside light-emitting devices.

An illumination device is provided with: a light source parthaving an LEDof a light source and a reflectorincluding a first reflection surfacewhich has a concavely curved cross section from one end to the other end and is formed so as to dispose the light source within this curved cross section and a second reflection surfaceclosing the curved cross section on the one end side; and a device main bodyincluding a top panel, an attachment part which is provided on a lower surface side of the top paneland attaches the light source partso as to make one end of the light source partbe positioned on the top plateside, and a side wall partwhich is disposed downward from the top paneland has a lower end edge partprovided below a straight line extending from the other end side of the LEDbeing the light source through a top end of the second reflection surface

Illumination device

A light source module has a reflector having a light reflection face and a plurality of light emitting elements. The light reflection face is curved in a circular arc shape in a width direction of the reflector and extends in a longitudinal direction of the reflector. The light emitting elements are arranged in a center portion in the width direction of the light reflection face and are arranged linearly along the longitudinal direction of the reflector.
