The mounting body 100 includes a mounting tool 110 that is mounted (fixed) on a mounting target part, and a mounting cover 120 that is mounted so as to cover the mounting tool 110.

The mounting cover 120 has an arm mounting hole 121 in which the arm 200 is mounted. The side surface of the mounting cover 120 is referred to as a mounting cover outer surface 122, and the shape formed by the mounting cover outer surface 122 is referred to as an outer shape.

The arm 200 includes a rod-shaped arm body 210 rotatably attached to the attachment cover 120, a washer 220, and a nut 230.

The arm body 210 has a threaded portion 211 formed on one end side and a arm support insertion hole 212 formed on the other end side. An outer surface of the side surface of the arm body 210 that forms the outer shape of the lighting fixture 1000 is referred to as an arm body outer surface 213, and a shape formed by the arm body outer surface 213 is referred to as an arm body outer shape.

A specific means for attaching the arm main body 210 to the attachment cover 120 will be described. The threaded portion 211 is inserted into the arm attachment hole 121 with the washer 220 inserted, and is further screwed into the nut 230, whereby the arm The main body 210 is fixed to the mounting cover 120 in a rotatable state.

The arm body 210 is rotatably attached to the attachment body 100 at one end side, and the lamp 300 is rotatably attached to the other end side.

Although not shown, the arm body 210 is hollow, and the electric wire drawn from the mounting body 100 is inserted into the hollow portion of the arm body 210 and drawn into the lamp 300. Therefore, the electric wire is drawn from the mounting main body 100 to the lamp 300 through the hollow portion of the arm main body 210, so that the electric wire cannot be seen from the lighting fixture 1000 (or in the slight gap between the arm main body 210 and the lamp 300). Is exposed to the outside), so that the design of the lighting fixture 1000 is improved.

It should be noted that the arm body 210 has a rotation restricting function of restricting rotation at 360° although it rotates axially (A direction in FIG. 1) with respect to the mounting surface of the mounting cover 120. In this rotation restricting mechanism, when the arm body 210 is rotated 360° or more (a plurality of rotations), the electric wire (the electric wire that connects the mounting body 100 and the lamp 300) wired inside the arm body 210 is unnecessarily increased. There is a risk of twisting, and it is intended to prevent problems such as disconnection due to twisting of the electric wire.

The lamp 300 includes a lamp unit 310, and a power supply unit 320 and a light source unit 330 housed inside the lamp unit 310.

The lamp unit 310 includes a lamp cover 311 for storing the power supply unit 320 and the light source unit 330, an arm support 312 built in the lamp cover 311, and a fixing for rotatably fastening the arm body 210 to the arm support 312.

An operation side end cover 316 and a light emitting side end cover 317 attached to the end of the lamp cover 311 are provided so as to hold the unit 330, the arm support 312, and the arm support attachment 314 in a stored state.

The lamp cover 311 has a cylindrical tubular portion 311a and a convex portion 311b from which the side wall portion of the tubular portion 311a projects. The side surface of the lamp cover 311 is called a lamp cover outer surface 311c, and the shape formed by the lamp cover outer surface 311c is called a lamp cover outer shape.

The outer shape of the lamp cover 311 is substantially the same as the outer shape of the mounting cover of the mounting cover 120.
The tubular portion 311a of the lamp cover 311 includes a power supply unit 320, a light source unit 330, a part of the arm support fixture 314, an adjusting portion 315, an operation side end cover 316, and a light emitting side end cover 317 inside the lamp cover 311. Store.

The convex portion 311b of the lamp cover 311 stores a part of the arm support tool 312 and the arm support mounting tool 314.

Further, the convex portion 311b of the lamp cover 311 is formed with a cutout portion 311ba that is cut in order to store and rotate the arm support tool 312.

The arm support tool 312 has a rod shape and is formed with a first arm storage part 312a in which the arm body 210 is stored. Further, a fixing tool 313 is inserted into the first arm storage part 312a to fix the arm body 210. A support tool insertion hole 312b communicating with the arm support tool insertion hole 212 is formed.

The fixture 313 has a support screw 313a and a nut 313b. The screw 313a is inserted into the arm support tool insertion hole 212 and the arm support tool insertion hole 212, and is fastened with the nut 313b. The screw 313a serves as a rotation shaft when the arm body 210 rotates.

The fixing tool 313 of the present embodiment will be described as a case of using the screw 313a and the nut 313b. However, if the arm main body 210 can be rotatably fixed, the fixing tool 313 is a different component or a different mechanism. It doesn't matter.

The arm support attachment 314 includes an arm support attachment attachment 314a to which the arm support 312 is attached, and a light source unit fixing portion 314b that fixes the light source unit 330 inside the cylindrical portion 311a.

In the adjusting unit 315, a dial as an operating portion is arranged at a position recessed from the end of the lamp cover 311. In this way, by disposing the adjusting portion 315 inside the cylindrical portion 311a of the lamp cover 311, the adjusting portion 315 does not project from the end portion of the lamp cover 311 and therefore the design is improved.

The operation-side end cover 316 is connected to the first arm storage portion 312a of the arm support tool 312 to store the arm body 210, and the adjustment portion insertion hole 316b through which the dial portion of the adjustment portion 315 is inserted. Is formed.

The second arm storage portion 316a is arranged inside the lamp cover 311 such that the storage portion is exposed from the cutout portion 311ba of the lamp cover 311 while being connected to the first arm storage portion 312a.

In the present embodiment, the case where the first arm storage part 312a and the second arm storage part 316a are divided into two will be described, but the first arm storage part 312a and the second arm storage part 316a are not integrated. In this case, it may be formed on the arm support tool 312 or the operation side end cover 316, or may be formed on the cutout portion 311ba of the tubular portion 311a.

The light emitting side end cover 317 has an opening 317a formed so that the light emitting portion of the light source unit 330 is exposed, and is fixed to contact the arm supporting fixture 314 and fix the arm supporting fixture 314 inside the lamp cover 311. The part 317b is formed.

The power supply unit 320 includes a power supply device 321 that supplies DC power (or AC power) to the light source unit 330, and a power supply case 322 that stores the power supply device 321.
The power supply case 322 is a bottomed tubular case having a bottom portion 322a.

The light source unit 330 includes a light source attachment 331 attached to the outer surface of the bottom portion 322 a of the power supply case 322, a light source 332 attached to the light source attachment 331, and a unit body 333 that is movable with respect to the power supply case 322 by the adjustment unit 315. And a lens 334 attached to the unit body 333, and a lens retainer 335 for fixing the lens 334 to the unit body 333.

The light source attachment 331 is preferably a metal plate in consideration of heat radiation of the light source 332, but when the heat radiation of the light source 332 is sufficient, for example, the light source attachment 311 is not limited to the metal plate, and the light source What is necessary is to fix 332 to the bottom portion 322a of the power supply case 322.

The light source 332 is, for example, a light emitting diode or an organic EL. In this embodiment, the light source includes a chip-on-board type LED and a socket for fixing the chip-on-board type LED to the light source mount 331.

The unit main body 333 includes a lens fixing portion 333 a that fixes the lens 334, and a movable support portion 333 b that covers the outside of the side surface of the power supply case 322.

The movable support portion 333b is connected to the adjustment portion 315 so as to slide the side surface of the power supply case 322 in the vertical direction by rotating the dial portion of the adjustment portion 315.

The lens 334 enters the light emitted from the light source 332, diffuses or condenses the light, and emits the light. The lens 334 is attached to the lens fixing portion 333a of the unit body 333. In addition, the lens 334 and the light source 332 are adjusted in distance by sliding the movable support portion 333b when the user rotates the dial which is the operation portion of the adjustment portion 315. That is, the distance between the incident portion of the lens 334 and the light emitting portion of the light source 332 is adjusted to be long or short. In this way, the light distribution angle obtained from the light source unit 300 is adjusted (widened or narrowed) by adjusting the distance between the lens 334 and the light source 332.

The lens retainer 335 has an opening 335a formed in the emitting portion of the lens 334 and a fixing portion 335b for fixing the lens 334 to the lens fixing portion 333a.

Next, the structures of the arm 200 and the lamp 300 will be described in more detail.
The length of the arm body 210 is substantially equal to or slightly longer than the combined length of the first storage portion 312a and the second storage portion 316a (excluding the space for the arm body 210 to rotate). That's it. That is, the arm body 210 has a length such that the end of the lamp 300 comes into contact with the mounting body 100, and when the arm body 210 is stored in the first storage portion 312a and the second storage portion 316a, the lamp cover 300 is provided. The lamp cover outer surface 311c may be flush with the mounting cover outer surface 122 of the mounting body 100.

In addition, the arm body outer surface 213 of the arm body 210 has a lamp cover outer surface 311c of the lamp cover 300 and a mounting cover of the mounting body 100 when the arm body 210 is stored in the first storage portion 312a and the second storage portion 316a. The shape is substantially flush with the outer surface 122.

In addition, since the shaft portion (fixing member 313) that connects the arm body 210 and the lamp cover 311 is formed on the side surface side (the convex portion 311b) of the lamp cover 311, the lamp 300 is eccentrically arranged and the arm body 210 is eccentric. The lamp 300 can be rotated around the fixture 313 as an axis.

Next, a case where the lamp 300 of the lighting fixture 1000 of the present embodiment is movable will be described.

For example, like the lighting fixture 1000 shown in FIG. 1, the lamp 300 is tilted in an oblique direction with respect to the mounting body 100 to illuminate the product displayed on the wall surface, the floor surface, or the product shelf.

The lamp 300 can be rotated horizontally (direction A in FIG. 1) with respect to the mounting surface of the mounting body 100 (mounting cover 120) by rotating the arm 200.

Next, the lamp 300 is rotated about the fixture 313 as an axis (direction B in FIG. 3) to arrange the lamp 300 horizontally or directly below the mounting body 100 (see FIGS. 4 and 5 ). ).

At this time, the outer shape of the mounting cover of the mounting body 100 and the outer shape of the lamp cover of the lamp 300 are substantially flush with each other, and the length of the arm body 210 is such that there is almost no gap between the mounting body 100 and the lamp 300. Therefore, the mounting body 100 and the lamp 300 can have an external shape as if they were composed of one component (one cylinder). Therefore, the external shapes of the mounting body 100 and the lamp 300 can be designed to be continuous and integrated, and the design of the lighting fixture 1000 can be improved.

Further, since the operation-side end of the lamp cover 311 is covered by the mounting body 100, that is, the mounting body 100 serves as a cover of the operation-side end of the lamp cover 311, the operation-side end cover. It becomes difficult for dust to collect in 313 and the adjustment unit 315. Furthermore, since the operation-side end portion is covered with the mounting body 100, the dial portion of the adjustment unit 315 cannot be operated from the outside, so that the light distribution angle of the light source unit 330 is changed by mischief (unintended operation). It can be prevented from being changed.

In addition, since the operation side end of the lamp cover 311 can be covered with the mounting cover 110, dust is less likely to be collected in the adjustment unit 315, and when the user operates the adjustment unit 315, the user's finger is less likely to get dirty. Further, since dust is unlikely to be clogged in the gap of the adjusting portion 315, the adjusting portion 315 is maintained in a state in which it can smoothly rotate.

Next, the arm 200 is rotated with the lamp 300 placed directly below the mounting body 100 (see FIGS. 4 and 5) (direction C in FIGS. 4 and 5 (same direction as direction A in FIG. 1)). ), and the tubular portion 311a of the lamp 300 does not overlap the mounting body 200 (see FIGS. 6 and 7 ), that is, the operation side end of the lamp cover 311 is exposed (the lamp cover 311 described above). The state is such that the lid on the end portion on the operation portion side is released). Therefore, a gap corresponding to the height of the mounting body 100 is formed between the mounted portion such as the ceiling where the mounting body 100 is mounted and the operation side end of the lamp cover 311. Therefore, since it is possible to operate the dial portion of the adjusting portion 315 by inserting a finger through the gap corresponding to the height of the mounting main body 100, the light distribution of the light source unit 330 can be performed in the state where the vicinity of the object to be illuminated is illuminated. You can change the corners. Therefore, the user can operate the dial portion of the adjusting unit 315 while confirming the state where the vicinity of the irradiation target is illuminated, so that the user can easily adjust to the desired light distribution angle.

In the present embodiment, the outer shape of the combination of the cylindrical portion 311a and the convex portion 311b of the cylindrical portion 311 has been described, but the outer shape of the mounting cover of the mounting body 100 and the outer shape of the lamp cover of the lamp 300 are substantially the same. Therefore, the outer shape of the lamp cover of the lamp 300 is not limited to the outer shape in which the cylindrical portion 311a and the convex portion 311b of the cylindrical portion 311 are combined, and may be a cylindrical shape or a polygonal prism shape. The shape may be a drum shape, a cone shape, a polygonal pyramid shape, or the like.

Further, in the present embodiment, the case of the lighting fixture has been described, but the present invention can be applied to other than the lighting fixture, for example, a portion corresponding to a lighting fixture has a function of a security camera or a projection unit of a projector. It may be an electronic device having the function of.
