The other end of the power supply device 35 in the longitudinal direction is connected to a power supply wire from the instrument body 12.

  In the present embodiment, the sensor 43 is a human sensor, and inputs a signal indicating whether or not a human body is sensed to the lighting circuit unit of the power supply device 35 via the electric wire 46. The lighting circuit unit turns on or off the light source unit or performs dimming according to the input signal. A pyroelectric infrared sensor is used as the human sensor, but other types of human sensors such as a camera may be used. The sensor 43 may be another type of sensor such as an illuminance sensor. That is, in the present embodiment, the sensor unit 14 exhibits a human sensor function by the sensor 43 that senses a person's movement in the direct downward direction, but performs other functions such as continuous light control and initial illumination correction. It may be a unit.

  The hooking portion 45 is connected to the third facing portion 41 on the side opposite to the first facing portion 42. In the present embodiment, a hooking portion 45 is formed in the second facing portion 49. The second facing portion 49 is provided so as to be perpendicular to the third facing portion 41 when viewed along the width direction X of the light source unit 13, that is, to extend in parallel with the first facing portion 42. . The second facing portion 49 has a hollow shape having a hollow portion on the inside, like the first facing portion 42 and the third facing portion 41. The second facing portion 49 is connected to the third facing portion 41 on the side opposite to the first facing portion 42. That is, the internal space of the second facing portion 49 communicates with the internal space of the third facing portion 41 on the side opposite to the internal space of the first facing portion 42. In the present embodiment, the first facing portion 42, the third facing portion 41, and the second facing portion 49 are integrally formed. The hook portion 45 projects from the surface of the second facing portion 49 facing the light source unit 13, that is, from the lower end surface of the second facing portion 49 so that the cross section forms a triangular shape. In a state where the sensor unit 14 is attached to the light source unit 13, the hook portion 45 is hooked on the light source lid portion 33 of the light source unit 13. Since the hooking portion 45 is fitted to a part of the light source unit 13, the sensor unit 14 can be easily attached to the light source unit 13 without requiring a special tool. Therefore, the deterioration of the assembling property and the detachability of the light source unit 13 due to the addition of the sensor function can be minimized.

  The inside of the sensor unit 14 is hollow from the first facing portion 42 where the sensor 43 is installed to the second facing portion 49 where the hooking portion 45 is formed. That is, a space 48 that communicates with each other is formed inside the first facing portion 42, the second facing portion 49, and the third facing portion 41. This space 48 is for housing the electronic component 44, and is used as a wiring path for wiring the electric wire 46 described above in this embodiment. Therefore, the deterioration of the detachability of the light source unit 13 and the damage of the electric wire 46 due to the exposure of the electric wire 46 can be prevented.

  In a state where the light source unit 13 is attached to the instrument main body 12 together with the sensor unit 14, a part of each of the second facing part 49 and the third facing part 41 is fitted into a notch 29 provided in the instrument main body 12. Yes. Therefore, interference between the sensor unit 14 protruding from the existing light source unit 13 and the instrument body 12 can be avoided. Therefore, the influence on the detachability of the light source unit 13 by mounting the sensor unit 14 can be eliminated, and the construction work becomes a work amount equivalent to that of the existing lighting fixture. The notch 29 may be provided only at one end in the longitudinal direction of the instrument body 12, but is provided at both ends in the longitudinal direction of the instrument body 12 in the present embodiment. For this reason, the light source unit 13 can be attached to the instrument body 12 regardless of whether the sensor unit 14 is attached to either end of the light source unit 13 in the longitudinal direction Y. In the present embodiment, the edge of the notch 29 is U-shaped, but the shape of the notch 29 matches the shape of the second facing part 49 and the third facing part 41 of the sensor unit 14. Can be changed as appropriate.

*** Explanation of the effect of the embodiment ***
In the present embodiment, the sensor unit 14 is light source unit so that a part of the sensor unit 14 crosses the one end surface 15 in the length direction Y of the light source unit 13 along the height direction Z of the light source unit 13. Therefore, the attachment of the sensor unit 14 and the stability when the sensor unit 14 is attached are improved.

  In the present embodiment, since the sensor unit 14 can be attached to the existing light source unit 13, it is not necessary to make the light source unit 13 a dedicated product, and only the relatively inexpensive instrument main body 12 is used as a dedicated product. Functions can be introduced.

  In the present embodiment, since the sensor unit 14 can be easily attached at a position where the light source unit 13 is not affected when the light source unit 13 is attached to or detached from the instrument main body 12, the sensor unit 14 is attached to the light source unit 13 in advance. No extra work is required, and construction work is equivalent to existing lighting fixtures.

*** Other configurations ***
In the present embodiment, the sensor unit 14 includes the electric wire 46 as the electronic component 44. However, as a modification, the sensor unit 14 may include other components. Differences from the present embodiment will be mainly described in the two modified examples.

  With reference to FIG. 5, the arrangement and configuration of the sensor unit 14 in the first modification will be described.

  FIG. 5 is a view showing a longitudinal section in which a portion from one end to the middle of the light source unit 13 in the length direction Y and the sensor unit 14 are cut along the length direction Y of the light source unit 13 as in FIG. It is.

In a state where the sensor unit 14 is attached to the light source unit 13, the electronic component 44 connects the power supply device 35 and the sensor 43. In this example, a substrate 50 that is one of the electronic components 44 is accommodated in the third facing portion 41. A sensor 43 is mounted on the substrate 50. The electric wire 46 connects the power supply device 35 and the substrate 50 instead of directly connecting the power supply device 35 and the sensor 43. Specifically, the electric wire 46 extends from the substrate 50 to the outside of the sensor unit 14 through the inside of the second facing portion 49, and is connected to one end in the longitudinal direction of the power supply device 35. The portion passing through the second facing portion 49 of the electric wire 46 may be a connector.

  With reference to FIG. 6, the arrangement and configuration of the sensor unit 14 in the second modification will be described.

  Also in this example, the electronic component 44 is housed in the second facing portion 49, the third facing portion 41, and the first facing portion 42. In a state where the sensor unit 14 is attached to the light source unit 13, the electronic component 44 connects the power supply device 35 and the sensor 43. In this example, the substrate 50, which is one of the electronic components 44, is housed in the first facing portion 42 instead of the third facing portion 41. On the substrate 50, not only the sensor 43 but also a timer switch 51 and a variable switch 52 are mounted. The electric wire 46 connects the power supply device 35 and the substrate 50 instead of directly connecting the power supply device 35 and the sensor 43. Specifically, the electric wire 46 extends from the substrate 50 to the outside of the sensor unit 14 through the third opposing portion 41 and the second opposing portion 49 in order, and is connected to one end in the longitudinal direction of the power supply device 35. ing.

  In this example, three through holes 47 are provided on the bottom surface of the first facing portion 42, and a part of the sensor 43, the timer switch 51, and the variable switch 52 is connected to the first facing portion 42 from the respective through holes 47. It protrudes downward. The timer switch 51 is a switch for adjusting the lighting holding time. The variable switch 52 is a switch for adjusting the sensitivity of the sensor 43.

  In the first modification, when the sensor 43 is mounted on the substrate 50, it is necessary to bend the lead terminal of the sensor 43, but in the second modification, such a process is not necessary. In the second modification, the substrate 50 can be made small.
