  However, since the luminaire shown in Patent Document 1 is provided with a sensor on the inner surface of the reflecting plate, there is a problem that the detection function of the sensor is hindered because the sensor is hidden by the reflecting plate on the side where the sensor is provided. . Further, since the projecting portion is provided on the reflecting plate, there is a problem that the light from the light source causes irregular reflection and affects the light distribution characteristics. Furthermore, there is a problem that protrusions and sensors are conspicuous on the inner surface of the reflector, and the merchantability is impaired in terms of appearance and design. Similarly, in Patent Document 2, an adapter including a remote control receiver is provided between a lighting fixture and a power source, in other words, as shown in FIG. Since it is inserted between the upper surface and the sensor as a receiving part is built in as shown in FIG. 1B, the instrument body becomes an obstacle and the detection range of the sensor becomes narrow. Further, in order to solve this problem, if the sensor is provided outside the main body case via the arm as shown in FIG. 1A, the detection range on the side opposite to the arm becomes narrow, and the sensor Since it is provided so as to protrude from the ceiling surface, it is not preferable in terms of appearance and design, and further, there arises a problem that an arm or a sensor is projected as a shadow on the ceiling surface to reduce the illumination effect. Further, in Patent Document 3, since an adapter provided with a remote control receiver is provided between an existing hook ceiling and an illumination lamp, a problem similar to that in Patent Document 2 occurs.

  On the other hand, in recent years, a flat and thin compact lamp with a cap has been used as a light source for a downlight or the like. This type of compact fluorescent lamp can be attached to and detached from a socket device that is directly attached to the ceiling surface as shown in Patent Document 4, in particular, paragraph numbers [0035] and [0056] and FIGS.

At the same time, the light distribution characteristics of the light source are affected, and appearance and design problems also occur, and further, the detection range of the sensor becomes narrow. This problem is not limited to the sensor. For example, when an auxiliary function member such as an auxiliary spotlight or a nightlight is added, the auxiliary function member protrudes to prevent downsizing of the instrument, and the light source This affects the light distribution characteristics, and also causes problems in appearance and design.

  The present invention has been made in view of the above problems, and even if these auxiliary function members are added, the light distribution characteristics are not affected, there is no problem in appearance and design, and further miniaturization is possible.

The socket device is configured by a fixture built-in type socket device in which the base member 15 of the GX53 type described in the first and second embodiments is electrically connected and used in a lighting fixture. As shown in FIG. 8, the socket device 20 houses a socket main body 21 made of a heat conductive member, a pair of terminal plates 22 to which the base member 15 of the lamp with cap 10-1 is electrically connected, and a terminal plate. And a pair of engaging holes 23 for mechanically coupling the cap-equipped lamp 10 and the socket body at the time of electrical connection to the cap-attached lamp.

  As with the lamp body 11, the socket body 21 is a metal having good thermal conductivity in order to enhance heat dissipation, and in this embodiment, the plane shape of the cross section made of aluminum is substantially circular and penetrates through the center. It is formed in a ring shape having a support hole 21a. The diameter d1 of the support hole 21a is slightly larger than the diameter d2 (FIG. 5B) of the outer peripheral surface of the protrusion 11a4 of the lamp body 11, in other words, the recessed fitting portion 11a5 (d1> d2). ) So that the recessed fitting portion 11a5 of the lamp body can be fitted into the support hole 21a of the socket body. The socket main body 21 having these configurations is processed by casting, forging, cutting, or the like, for example.

  When the pair of base members 15 in the GX53 format of the lamp with cap 10-1 are electrically connected, the terminal plate 22 comes into contact with the cap member 15 to supply commercial power to the lamp with cap 10-1. It is composed of a terminal board with a spring property that is bent into a "<" shape made of a metal having a certain rigidity and spring property and good conductivity, such as copper, brass, phosphor bronze, etc. To do. As shown in FIG. 8, the terminal board 22 is housed and supported in an engagement hole 23 of a support body 22b formed of a heat-resistant and electrically insulating synthetic resin such as PBT on a square pole. The engagement hole 23 is formed by a so-called “Dalma hole” of a locking hole 23a formed of an arc-shaped long hole and an insertion hole 23b formed of a circular hole formed continuously at one end of the locking hole. The diameter dimension of the insertion hole 23b is formed larger than the diameter dimension of the plug portion 15b of the base member 15, and the width dimension of the long hole of the locking hole 23a is formed smaller than the diameter dimension of the plug portion 15b. As a result, the plug portion 15b of the base member 15 is inserted from the insertion hole 23b and moved to the locking hole 23a made of a long hole, so that the plug portion 15b contacts the terminal plate 22 accommodated in the engagement hole 23. Thus, the electrical connection is made, and the plug portion 15b is locked to the back surface side of the locking hole 23 to prevent the plug portion 15b from coming off from the engaging hole 23 and is mechanically held.

  As described above, a pair of support bodies 22b accommodating the terminal plate 22 is prepared, and as shown in FIG. 8A, a pair of squares formed on the surface of the socket body 21 so as to face each other in the diametrical direction. Are respectively fitted in the support holes 21b and fixed with an adhesive made of silicone resin, epoxy resin or the like. In this state, the engagement hole 23 made of a dharma hole is arranged so as to be point-symmetric with respect to the center point a of the ring-shaped socket body 21. As a result, as shown in FIG. 9, the plug portion 15b of the base member 15 is inserted from the insertion hole 23b and moved to the locking hole 23a, that is, the angle α1 about the center point a of the socket body 21 is shown. 9, the plug portion 15b of the base member 15 comes into contact with the terminal plate 22 and further gets over the protruding portion of the “<” shape of the terminal plate to make electrical connection. At the same time, the plug portion 15b is locked to the back side of the locking hole 23a and mechanically held.

As shown in FIGS. 9 and 12, the pair of base members 15 of the lamp with cap 10 are opposed to the engagement holes 23 of the socket device 20, and the plug portion 15b of the base member 15 is inserted into the insertion hole 23b. Then, in FIG. 9, it is rotated by an angle α1 in the direction of the arrow. As a result, the plug portion 15b of the base member 15 contacts the terminal plate 22 to be electrically connected, and at the same time, the plug portion 15b is locked to the back side of the locking hole 23a and mechanically held. In addition, the lamp | ramp 10-1 with a base with a sensor can be removed from the socket apparatus 20 by rotating in a reverse direction.

When the power is turned on in this state, the power is supplied from the socket device 20 through the base member 15 of the lamp with cap 10-1, and the lighting device 14 operates to output a DC voltage of 24V. This DC voltage is applied from the lighting device 14 to each LED 12a, and a constant DC current is supplied to light all the LEDs simultaneously. The white light radiated from each LED 12a is radiated substantially uniformly toward the entire inner surface of the cover member 11b, and the light is diffused by a milky white glove to perform illumination with a predetermined light distribution characteristic. At this time, since the sensor 13 is provided at substantially the center of the lamp body 11 and the sensor is not provided on the inner surface of the reflecting plate, there is no problem that affects the reflecting performance of the reflecting plate, and it is uniform over substantially the entire circumference of the fixture. Illumination with excellent light distribution characteristics can be performed. Further, there is no problem that the merchantability is impaired in appearance and design as an instrument. In addition, the light emitting part 12 of the lamp with cap 10-1 with sensor is such that the light emitting part 12 composed of six LEDs 12a is located around the opening 11c on one side of the lamp body 11 and is connected in an annular shape. Since the annular light emitting portion having a donut shape disposed in the lamp body is configured, illumination with more uniform light distribution characteristics can be performed over substantially the entire periphery of the fixture.

  At the same time, the sensor 13 operates to detect a human body, brightness, heat, and the like. For example, when a person comes out of a room, the human body sensor detects that there is no person and automatically turns off the light. Further, when the room is brightened by sunlight in the daytime, the brightness is detected by the brightness sensor, for example, a 50% dimming signal is transmitted, and the output of the LED 12a is reduced by about 50%. Let's do energy-saving lighting. At this time, since the sensor 13 is provided in the substantially central portion of the lamp body 11 and is not provided in the reflector, the detection function of the sensor is not hindered, and a uniform detection range is set over substantially the entire periphery of the instrument. , Can reliably detect the room situation. Further, since the light shielding plate 13c1 is provided around the detection element 13b with a predetermined height, the detection element 13b is not affected by the light emitted from the light emitting unit 12, and is more reliable by the sensor. Detection can be performed.

  Moreover, when the lamp | ramp 10-1 with a nozzle | cap | die will be lighted, the temperature of LED12a will rise and a heat | fever will generate | occur | produce. The heat is transmitted from the circuit board 12b made of aluminum having good thermal conductivity to the board support portion 11a2 to which the board is directly adhered and fixed, and is passed from the outer peripheral surface of the case body 11a made of aluminum through the heat radiation fins 11a6. To dissipate heat. The heat generated from the electronic component 14c of the lighting device 14 is radiated to the outside from the case body 11a. By these heat radiation effects, the temperature rise of the LED 12a and the temperature rise of the electronic component 14c in the lighting device 14 are suppressed.

  As described above, according to the lighting fixture of the present embodiment, since the sensor 13 is provided in the substantially central portion of the lamp main body 11, there is no problem affecting the reflection performance of the reflecting plate, and it is uniform over substantially the entire circumference of the fixture. Illumination with light distribution characteristics can be performed. In addition, since the sensor is not provided on the reflection plate, it is possible to provide a lighting fixture that does not have a problem of detracting from the appearance and design as a fixture. In addition, since the annular light emitting unit 12 is provided around the opening 11c, illumination with substantially uniform light distribution characteristics can be performed over the entire periphery of the lamp body 11.

  At the same time, since the sensor 13 is not provided on the reflector, the detection function of the sensor is not hindered, and a uniform detection range is set over almost the entire periphery of the instrument, so that the situation of the room or the like can be detected reliably. it can.
