In this embodiment, the 1st reflection part 31 and the 2nd reflection part 32 are integrally molded. The boundary between the first reflecting portion 31 and the second reflecting portion 32 is a straight line (not shown) connecting the radial center of the shade 56 and the end of the second edge portion 41.

  As shown in FIGS. 2 and 3, the sensor unit holding part 40 is a part that holds the sensor unit 70. The sensor unit holding part 40 is integrally formed with the lighting fixture body 10. The inner shape of the sensor unit holding part 40 is formed in a shape corresponding to the outer shape of the unit case 73 so that the sensor unit 70 can be held.

  The sensor unit holding part 40 has a sensor arrangement surface 42 and a side wall part 43. The sensor arrangement surface 42 is a portion facing the sensor unit 71 and the switch 72 in a state where the sensor unit 70 is held. The sensor arrangement surface 42 is provided with a first through hole 44 formed corresponding to the position of the sensor unit 71 and a second through hole 45 formed corresponding to the position of the switch 72. The first through-hole 44 is a through-hole that protrudes so that the translucent sensor unit 71 faces the irradiation surface side (lower surface side) of the lighting fixture body 10 in a state where the sensor unit 70 is held by the sensor unit holding unit 40. is there. The first through hole 44 is provided on the center side of the frame part 26 with respect to the frame part 26, and the sensor part 71 is provided on the center side of the frame part 26 with respect to the frame part 26. That is, the sensor unit 71 is provided inside the frame unit 26 in the radial direction. The second through hole 45 is a through hole that allows the switch 72 to be operated from the irradiation surface side (lower surface side) of the luminaire main body 10 in a state where the sensor unit 70 is held by the sensor unit holding portion 40.

  The side wall portion 43 is formed substantially perpendicular to the sensor arrangement surface 42 and constitutes a space in which the sensor unit 70 is accommodated. The end of the side wall 43 constitutes an insertion port 46 for inserting the sensor unit 70. A screw hole 48 for fixing the sensor unit 70 with, for example, a screw 47 is formed around the insertion port 46.

  As shown in FIG. 3, when the sensor unit holding unit 40 holds the sensor unit 70, the packing 49 is interposed between the peripheral edge of the insertion port 46 of the sensor unit holding unit 40 and the flange 74 of the sensor unit 70. Then, the screw 47 is screwed into the screw hole 48 to fix the sensor unit 70 to the sensor unit holding portion 40.

  According to the lighting fixture 100 which concerns on this embodiment demonstrated above, it has the following effects.

  According to the lighting fixture 100, the 1st reflection part 31 and the 2nd reflection part 32 are formed in the surface which continues smoothly. For this reason, the light emitted from the light source 50 is not unnaturally blocked or reflected unnaturally at the continuous portion of the first reflecting portion 31 and the second reflecting portion 32, and the light distribution is improved. .

  According to the lighting fixture 100, the first edge portion 27 and the second edge portion 41 constituting the opening 24, and the first reflection portion 31 and the second reflection portion 32 are integrally molded. For this reason, in the continuous part of the 1st edge part 27 and the 2nd edge part 41, and the continuous part of the 1st reflective part 31 and the 2nd reflective part 32, the irradiation light from light source 50 is interrupted unnaturally, Difficult to reflect unnaturally, improving the light distribution.

In the luminaire of Patent Document 1, since the sensor unit protrudes in the reflector, the sensor unit erroneously detects the irradiation light from the light source. Due to erroneous detection of the sensor unit, for example, there is a possibility that a malfunction such as unnecessary repeated lighting and extinction (chattering) may occur.
On the other hand, according to the lighting fixture 100, the second reflecting portion 32 and the sensor arrangement surface 42 are partitioned by the second edge portion 41. For this reason, the 2nd reflection part 32 can shield the irradiation light which goes to the sensor part 71 from the light source 50, and can prevent chattering.

  According to the lighting fixture 100, the lighting fixture 100 has a side wall portion 43 that is formed substantially perpendicular to the sensor arrangement surface 42 and that constitutes a space in which the sensor unit 70 is accommodated. For this reason, the sensor unit 70 can be attached easily and reliably. Moreover, since the sensor unit holding | maintenance part 40 is shape | molded with the aluminum alloy, the light irradiated from the light source 50 does not permeate | transmit, and it prevents that the sensor part 71 misdetects.

The lighting fixture of patent document 1 needs to interpose packing between a reflecting plate and a sensor part, when high airtightness is required. Since the reflector and the sensor unit are combined in a three-dimensional shape, the packing also has a complicated shape. The packing having a complicated shape is not only high in cost but also tends to be less airtight because the degree of adhesion tends to be uneven.
On the other hand, according to the lighting fixture 100, the packing 49 interposed between the sensor unit 70 and the sensor unit holding part 40 is arrange | positioned in the peripheral part of the insertion port 46. FIG. Since the peripheral edge of the insertion port 46 has a flat shape and the lower surface of the flange 74 (the surface facing the peripheral edge of the insertion port 46) has a flat shape, the packing 49 has a simple shape (for example, a uniform thickness). The packing 49 is less expensive and airtightness can be easily secured.

  According to the lighting fixture 100, the sensor unit holding unit 40 is integrally formed with the lighting fixture main body 10. For this reason, assemblability improves compared with the case where the sensor unit holding | maintenance part 40 is comprised with respect to the lighting fixture main body 10 separately.

In the lighting fixtures disclosed in Japanese Patent Application Laid-Open Nos. 2005-346957 and 2005-251600, a sensor unit is provided on the outer side of the frame portion that forms the outer edge on the irradiation surface side of the lighting device. When the sensor part is provided outside the frame part, the lighting fixture is enlarged and the design is deteriorated.
Moreover, the lighting fixture disclosed by FIG. 10 of Unexamined-Japanese-Patent No. 2003-86019 is provided with the sensor part inside the frame part which comprises the outer edge by the side of the irradiation surface of a lighting fixture. As described in paragraph 0006 of Patent Document 4, this lighting fixture is provided with a sensor portion outside the light source, and a frame portion having a size including the light source and the sensor portion. For this reason, an external dimension becomes large compared with the lighting fixture which contains only the light source.
On the other hand, according to the lighting fixture 100, the sensor unit 71 is provided on the center side of the frame unit 26 with respect to the frame unit 26. Compared to the configuration in which the sensor unit is provided outside the conventional frame unit and the configuration in which the frame unit having a size including the light source and the sensor unit is provided, the lighting device 100 becomes compact and the design of the lighting device 100 is improved. improves.

  According to the lighting fixture 100, the first connection line 55 that electrically connects the lighting control circuit 61 and the light source 50 is wired at a position where the circuit housing portion 60 overlaps the heat radiating portion 21, and the lighting control circuit 61 and the sensor unit are connected. The second connection line 75 that is electrically connected to 70 is wired at a position where the circuit housing portion 60 overlaps the sensor unit holding portion 40. For this reason, the lighting control circuit 61 and the light source 50 and the lighting control circuit 61 and the sensor unit 70 can be connected at a short distance, wiring is easy, and assemblability is improved. Moreover, since the circuit accommodating part 60 is arrange | positioned so that it may overlap with the sensor unit holding | maintenance part 40 and the thermal radiation part 21, the lighting fixture 100 becomes compact.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment.

  For example, as shown in FIGS. 5 and 6, a part of the first through hole 44 may be disposed so as to overlap the frame portion 26. Thereby, the sensor unit 71 is disposed so that a part thereof overlaps the frame unit 26. In this case, even in a small lighting fixture 100 (the diameter of the frame portion 26 is small), the size of the opening 24 can be secured and the light distribution can be improved.

  Further, as shown in FIGS. 5 and 6, the second reflecting portion 32 may be formed substantially perpendicular to the sensor arrangement surface 42. In this case, the second reflection unit 32 blocks the irradiation light from the light source 50 toward the sensor unit 71. Therefore, since it becomes difficult for incident light (infrared rays) to enter the sensor unit 71, chattering of the sensor unit 71 can be prevented. In particular, as shown in FIGS. 5 and 6, a flat surface 33 may be formed on the second reflecting portion 32, and the flat surface 33 may be formed substantially perpendicular to the sensor arrangement surface 42. In this case, the flat surface 33 can block the irradiation light directed from the light source 50 toward the sensor unit 71 and prevent chattering.

  As shown in FIG. 7, a light shielding part 34 that shields irradiation light from the light source 50 toward the sensor part 71 may be formed on the second edge 41. In this case, the light shielding unit 34 shields irradiation light from the light source 50 toward the sensor unit 71. Therefore, since it becomes difficult for incident light (infrared rays) to enter the sensor unit 71, chattering of the sensor unit 71 can be prevented.

  As shown in FIGS. 8 and 9, the light source 50 may be offset from the center of the frame portion 26 so that the light source 50 is separated from the lighting control circuit 61. 8 and 9, the center of the frame portion 26 is C1, the center of the light source 50 is C2, and the radial offset amount of the center C2 of the light source 50 with respect to the center C1 of the frame portion 26 is L. The direction in which the center C2 of the light source 50 is offset from the center C1 of the frame portion 26 is a direction in which the light source 50 is separated from the lighting control circuit 61. In this case, the light source 50 that is a heat generation source and the lighting control circuit 61 are separated from each other, and the heat dissipation of the light source 50 and the lighting control circuit 61 can be improved.
