[0025] 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.

[0026] 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.

[0027] like Figures 1-7 As shown, the stepless adjustable floodlight in this embodiment includes an illumination part and a support part, which are rotatably connected. The illumination part can be infinitely rotated around the support part for adjustment.

[0028] Specifically, the lighting unit includes a lighting housing 10 and a lamp plate 20 disposed within the lighting housing 10. Lamp beads are disposed on the lamp plate 20 to provide a light source. The lighting housing 10 includes a bottom housing 11, a reflector 12, a lampshade 13, and an aluminum heat sink 14. The reflector 12 is disposed above the lamp plate 20, and the lampshade 13 covers the bottom housing 11. A wire outlet hole 111 is provided on the front side of the bottom housing 11. The reflector 12 is narrow at the bottom and wide at the top, surrounding the position above the lamp plate 20. The upper end of the reflector 12 extends to the position of the lampshade 12. The heat sink aluminum plate is attached to the position below the lamp plate 20 and is attached to the bottom surface of the bottom housing 11. The bottom housing is made of thermally conductive nylon material for heat dissipation.

[0029] The lampshade 13 has multiple snap-fit ​​bodies 131 around its lower perimeter, and the upper inner side of the bottom housing 11 has multiple fastening plates 112. The snap-fit ​​bodies 131 and the fastening plates 112 are inserted into each other. The snap-fit ​​bodies 131 have a hook-shaped structure, and the fastening plates 112 have holes for the snap-fit ​​bodies 131 to pass through. Thus, the snap-fit ​​bodies 131 snap into the fastening plates 112 to achieve the insertion fit. At the same time, the upper end of the bottom housing 11 has an inwardly recessed glue groove 113, which can be used to apply waterproof glue to improve the waterproof effect.

[0030] Additionally, the support includes a base 40 and a junction box 50 disposed on one side of the base 40. The junction box 50 has a sealing groove 51 at the end facing the base 40, and a waterproof ring 52 is disposed in the sealing groove 51.

[0031] The base 40 includes a lower housing 41 and a rear housing 42 disposed on the rear side of the lower housing 41. The connector 32 is disposed on the front side of the lower housing 41. The junction box 50 is inserted into the rear housing 42. The lower housing 41 has a first inlet hole 411 on the front side and the rear housing 42 has a second inlet hole 421 on the front side. The lower housing 41 has a groove 412. The groove 412 contains an inlet pipe 413. The inlet pipe 413 is connected to the first inlet hole 411. The power cord of the lamp board 20 passes through the outlet hole 111, passes through the first inlet hole 411, the inlet pipe 413 and the second inlet hole 421 in sequence, and enters the junction box 50 of the rear housing 42.

[0032] Here, there is a gap between the bottom wall of the bottom housing 11 and the upper end face of the lower housing 41. That is, when the side wall of the bottom housing 11 abuts against the side wall of the lower housing 41, the bottom wall of the bottom housing 11 is inclined and there is an angle between it and the upper end face of the lower housing 41. This, together with the groove 412 structure, provides heat dissipation space.

[0033] The lighting housing 10 has a connecting body 31 on one side, specifically the front side of the bottom housing 11, and a connecting body 32 on the other side, specifically the front side of the lower housing 41. The connecting body 31 and the connecting body 32 are columnar structures. The connecting body 31 and the connecting body 32 are provided with shaft holes for the connecting piece 33 to pass through. The connecting piece 33 adopts a bolt structure, which provides locking and the function of the connecting body 31 rotating around it. At the same time, the connecting body 31 and the connecting body 32 are provided with annularly distributed toothed ribs 34 at the opposite end. An elastic gasket 35 is sandwiched between the toothed ribs 34 of the connecting body 31 and the connecting body 32.

[0034] Thus, through the cooperation of the elastic pad 35 and the toothed rib 34, a damping friction force is provided. After the connector 33 is tightened, the lighting part can be rotated by human force to overcome the resistance. When the external force is lost, the lighting part is fixed and will not rotate under the action of the elastic pad 35 and the toothed rib 34, thus achieving angle fixation.

[0035] 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 used in the detailed description should not be construed as indicating any essential elements for practicing the invention beyond the claims.

[0036] This invention includes all improvements encompassed by the spirit and scope of the invention as defined in the claims. Furthermore, unless otherwise stated or there is a clear contradiction in the content, this invention includes any of the foregoing elements and all possible variations thereof.
