[0029] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments.
[0030] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0031] like Figures 1-7 As shown, the rotatable LED downlight in this embodiment includes a barrel body 10, a rotating part disposed inside the barrel body 10, and an illumination part connected to the rotating part. The illumination part can rotate with the rotating part, as well as a conventional driver 40 and a wire 50. A top cover 11 is provided on the top of the barrel body 10. The wire 50 passes through the top cover 11 and into the barrel body 10 and is electrically connected to the illumination part.
[0032] Conventionally, a retaining spring 60 is installed on the body 10 to enable the installation of the downlight.
[0033] The rotating part includes an inner ring 21, a limiting ring 22 and a rotating ring 24 connected to the cylinder body 10. The rotating part is generally coaxial with the cylinder body 10. The lighting part includes a radiator 31, an outer ring 32 and a lamp plate 33, a lens 34 and a reflector bowl 35 disposed between the radiator 31 and the outer ring 32. The lighting part is inclined.
[0034] Specifically, the inner ring body 21 includes a base 211, which is connected and fixed to the cylinder body 10 by bolts. The base 211 has an inward annular protrusion 212, and a stepped surface 213 is formed between the annular protrusion 212 and the inner wall of the base 211. A plurality of mating plates 214 are provided above the base 211, and there are mating grooves 215 between adjacent mating plates 214.
[0035] Furthermore, multiple mating plates 221 and 222 protrude outward from the limiting ring 22. The mating plates 221 cover the mating plate 214, and the mating plates 222 are inserted into the mating groove 215. The limiting ring 22 covers the inner ring body 21. There is a ring-shaped rotating groove 23 between the limiting ring 22 and the inner ring body 21. There is a gap between the lower end face of the limiting ring 22 and the step surface 213, thereby forming the rotating groove 23. Thus, the rotating ring 24 is disposed in the rotating groove 23. The rotating ring 24 can only rotate along the rotating groove 23. The rotating ring 24 is connected to the lighting unit and thereby drives the lighting unit to rotate.
[0036] Among them, a first limiting body 241 is provided on one side of the rotating ring 24, and a second limiting body 242 is provided on one side of the limiting ring 22. The first limiting body 241 will contact the second limiting body 242 during the rotation of the rotating ring 24 and cannot pass through the second limiting body 242, thereby limiting the rotation angle and preventing more than one 360° rotation in the same direction.
[0037] The reflector bowl 35 is placed on the lens 34, and the heat sink 31 is threadedly engaged with the outer ring 32. Waterproof colloid is provided at the threaded engagement point to achieve waterproof and dustproof protection.
[0038] In addition, the heat sink 31 includes a main housing 311 and a plurality of heat sink plates 312 disposed above the main housing 311. An internal thread is provided at the lower edge of the main housing 311, and an external thread is provided on the outer ring 32 to realize threaded connection. The lamp plate 33 and the lens 34 are disposed inside the main housing 311, thereby fixing the lamp plate 33, the lens 34 and the reflector bowl 35 inside.
[0039] A connecting seat 313 is provided on one side of the main housing 311. Correspondingly, a plurality of connecting bodies 243 are provided on the rotating ring 24. The connecting bodies 243 are connected to the connecting seat 313. Connecting holes are provided on both sides of the connecting seat 313 and on the connecting bodies, and screws are screwed in for connection and fixation.
[0040] To facilitate cable routing, a cable guard 61 is inserted and installed above the cylinder body 10, and a cable clamp 62 is installed on the radiator 31. The power supply cable 50 passes through the cable guard 61 and the cable clamp 62. The cable guard 61 and the cable clamp 62 can be plate-shaped with openings for the power supply cable 50 to pass through, thereby limiting and fixing the power supply cable 50. At the same time, a flexible tube can be put on the connection position of the power supply cable 50 with the cable guard 61 and / or the cable clamp 62 for further fixation.
[0041] All descriptions herein may be presented in any suitable order. Any and all instances used, or exemplary language provided herein (such as "for example"), are merely for the purpose of better illustrating the invention and are not intended to limit the scope of the invention, except as provided in the claims. The language in the detailed description should not be construed as indicating any essential elements for practicing the invention beyond the claims.
[0042] This utility model describes preferred embodiments, including the best mode known to the inventors for carrying out the utility model. Of course, variations of these preferred embodiments will be readily apparent to those skilled in the art. The inventors intend that those skilled in the art may use these variations as appropriate, and the inventors indicate that the utility model can be implemented in other ways than those specifically described herein. Therefore, this utility model includes all improvements encompassed by the spirit and scope of the utility model as defined by the claims. Moreover, unless otherwise stated or there is a clear contradiction in the content, this utility model includes any of the foregoing elements and all possible variations thereof.
