Abstract
The utility model provides a lighting device. The lighting device improves the freedom degree of the illumination direction of light, and a lamp body is easy to replace. If the lamp body is rotated in the preset direction along the inner circumference of a rotating frame, a convex part abuts against a convex part of a rotating body to limit rotation. Moreover, if the lamp body is rotated in the preset direction along the inner circumference of the rotating frame, the rotating frame is rotated in the preset direction along with the lamp body, and the convex part abuts against a first rotation limiting part (or a second rotation limiting part). When the lamp body is installed on the rotating frame, the rotating body embedded into the rotating frame enables a claw part and the portion close to the claw part of a clamping and stopping claw to expand through elastically deforming toward the outer circumference of the rotating frame, then while the embedded front end of the rotating body of the lamp body abuts against the inner circumference part of the foot of the rotating frame, elastic deformation of the claw part and the portion close to the claw part of the clamping and stopping claw recovers, wherein the claw part and the portion close to the claw part expand toward the outer circumference, and the claw part is pressed and embedded into the upper end of the rotating body of the rotating frame.

［ embodiment ］
(formation of lighting device)
Fig. 1 is the stereogram that the lighting device of embodiment is shown.In addition, Fig. 2 is the exploded perspective view of the lighting device of embodiment.Fig. 1 and Fig. 2 are stereograms when the tilted direction of top is observed the lighting device 1 of embodiment from the opposition side of the direction of illumination of light.The profile of lighting device 100 is cuboid roughly.Lighting device 100 has underframe 101, sidewall 102, decorative panel 103, only plate 104, the lid 106 of pressure of lamp body 10, rotating frame 30, essentially rectangular.Erect and be provided with sidewall 102 on four limits of underframe 101.Decorative panel 103 is plates of the general square shape of around being surrounded by sidewall 102.Press only plate 104 to be configured to and on the sheet material of general square shape, be provided with the roughly circular hole that lamp body 10 is inserted.Lid 106 covers sidewall 102.
In lighting device 100, dispose lamp body 10 in the interior volume of being surrounded by sidewall 102.Lamp body 10 has fin 11 and rotating main body 20.Fin 11 is formed as general triangular shape by the metal of the fine heat radiation properties such as die casting aluminium.Rotating main body 20 is formed as roughly cylindric by metals such as die casting aluminium.In lighting device 100, the member except lamp body 10 is called to framework.In addition, the fin of lamp body 10 11 sides are called to top, rotating main body 20 sides are called to below.
In rotating frame 30, with decorative panel 103 with press plate 104 only to clamp the foot of the edge shape of rotating frame 30.Rotating main body 20 is embedded in rotating frame 30.Due to the decorated plate 103 of foot of the edge shape of rotating frame 30 with press only plate 104 to clamp, so rotating frame 30 can be along the sliding and rotate of roughly circular hole of pressing plate 104 only in interior week on decorative panel 103.
In addition, on the ceiling that lighting device 100 is arranged on to building, decorative panel 103 be with together with the part of the below of lamp body 10 can from beneath to parts ingenious.Owing to sliding and rotate by decorative panel 103 and the foot that presses plate 104 only to clamp the edge shape of rotating frame 30, so decorative panel 103 and to press only plate 104 be exactly the installing plate of rotating frame 30.
Rotating frame 30 is by for example ABS(Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene (ABS)) formation such as resin.The foot of the edge shape of rotating frame 30 has: be positioned at the perisporium of rotating frame 30 outer circumferential side outer peripheral portion and be positioned at the circumferential portion of inner circumferential side of the perisporium of rotating frame 30.By decorative panel 103 and press the foot of the rotating frame 30 that only plate 104 clamps to be positioned at the outer peripheral portion 25a(of outer circumferential side of the perisporium of rotating frame 30 with reference to Fig. 6).In addition, the circumferential portion 25b(of the inner circumferential side of the perisporium that is arranged in rotating frame 30 in the foot of rotating frame 30 is with reference to Fig. 6) support from the direction of underframe 101 sides the rotating main body 20 that is embedded in rotating frame 30.
In addition, rotating frame 30 has engagement pawl 31a, 31b, 31c.Engagement pawl 31a～31c is roughly equally spaced set on the side face of rotating frame 30.Engagement pawl 31a～31c is arranged on respectively between two otch that form in the side of the rotating frame 30 of tubular.Engagement pawl 31a～31c has the claw of the upper end of pressing the rotating main body 20 being embedded in rotating frame 30 near the otch of rotating frame 30.
,, while lamp body 10 being installed on rotating frame 30, being embedded in rotating main body 20 in rotating frame 30 and making near the claw of engagement pawl 31a～31c and claw to expand towards the peripheral direction strain of rotating frame 30.And then, in the embedding front end of rotating main body 20 of lamp body 10 and the interior circumferential portion butt of the foot of rotating frame 30, near strain claw and the claw of the engagement pawl 31a～31c expanding towards peripheral direction is restored, and claw is pressed the upper end of the rotating main body 20 being embedded in rotating frame 30.By rotating main body 20 is embedded in rotating frame 30, pressing only plate 104 to be arranged on sidewall 102, lamp body 10 is mounted to can be along the rotation of sliding in interior week of rotating frame 30 in lighting device 100 inside.
In addition, as shown in Figure 2, on the week of the upper end of rotating frame 30, there is protuberance 32.At the rotating main body 20 of lamp body 10 that is installed on rotating frame 30 along circumference when rotation of rotating frame 30, protuberance 21 butts of protuberance 32 and rotating main body 20 described later.By the protuberance 32 of rotating frame 30 and protuberance 21 butts of rotating main body 20, restricting rotation main body 20 exceedes 360 ° of rotations with respect to rotating frame 30.By this restriction, prevent that the cable (not shown) for power supply supply etc. being for example connected with lamp body 10 from twisting together or twisting off.
In addition, rotating main body 20 is the frictional resistance materials different with torque while having considered that rotating main body 20 rotates with respect to rotating frame 30 with rotating frame 30.For example, rotating main body 20 and rotating frame 30 also can be metal.Or for example, rotating main body 20 and rotating frame 30 also can be resin.Or for example, some in rotating main body 20 and rotating frame 30 is metal, another is resin.Or for example, rotating main body 20 and rotating frame 30 also can be formed by the material with different coefficients of friction.By like this, rotating main body 20 can rotate with appropriate frictional resistance reposefully with respect to rotating frame 30, can keep postrotational position simultaneously, can prevent unexpected rotation.
