The rotary cover drives the lens to move axially in the inner cavity of the lamp body through the transmission structure, thereby adjusting the distance between the light output component and the lens to achieve the purpose of focusing. However, this structure has the following disadvantages: there is a gap between the rotary cover and the end of the lamp body. In outdoor use scenarios, external rainwater can enter the inner cavity of the lamp body through the aforementioned gap, thereby affecting use. Utility Model Content

[0037] The following is a detailed description of the implementation of the present invention in conjunction with the accompanying drawings. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention.

[0038] See also Figure 1-Figure 3 In this embodiment, a floodlight includes:

[0039] The lamp body 1 has a sealed light source cavity 11, and a light emitting component 12 is arranged in the light source cavity 11;

[0040] The cylinder 2 is coaxially sleeved on the outer side of the lamp body 1;

[0041] The lens 21 is coaxially disposed at one end of the barrel 2 away from the lamp body 1 . The barrel 2 can slide along the axial direction of the lamp body 1 and drive the lens 21 to move relative to the light emitting assembly 12 .

[0042] In the prior art, as shown in the attached Figure 4 As shown in the figure, it includes a lamp body 3, a transmission structure 31, a rotary cover 32 rotatably matched with the lamp body 3, and a lens 33 built into the inner cavity of the lamp body 3. The rotary cover 32 drives the lens 33 to move axially in the inner cavity of the lamp body 3 through the transmission structure 31.

[0043] In this embodiment, the lens 21 is arranged on the outside of the lamp body 1 through the barrel 2, and the barrel 2 is used to slide relative to the lamp body 1 to drive the lens 21 to move relative to the light-emitting component 12 to achieve the focusing effect. Compared with the prior art, the present application cancels the internal transmission structure and the rotating cover for driving, which can avoid the appearance of a gap at the end of the lamp body 1, thereby achieving a better waterproof effect, simplifying the structure, and reducing the cost of production. On the other hand, compared with the built-in lens 21, the external lens 21 can reduce the absorption of light, which is beneficial to improving the light efficiency of the product; in the setting scheme of the built-in lens 21, due to the gap between the light-emitting component 12 and the light-emitting plate A larger space is left, and the aforementioned space is used to assemble the lens 21 and prevent the lens 21 from moving axially, and the space also includes components for supporting the lens 21. Therefore, when the light is emitted, most of the light is absorbed, thereby affecting the light effect of the product. In this embodiment, an external lens 21 is used to meet the basic focusing requirements, while reducing the axial size of the light source cavity 11 and reducing the absorption of light, thereby improving the light effect of the product. It is particularly suitable for large-angle application scenarios. The light-emitting component 12 of this embodiment includes a circuit board and LED lamp beads arranged on the circuit board, and the circuit board is electrically connected to an external power supply through wires.

[0044] In this embodiment, an annular boss is provided outwardly at the edge of the lens 21, and an annular assembly portion is provided inwardly at the inner cavity of the cylinder 2. The annular boss is bonded to the annular assembly portion by glue.

[0045] Preferably, it also includes:

[0047] In this embodiment, the anti-glare cover 22 is in a semi-arc shape, having a highest point and a lowest point, and the anti-glare effect is achieved by using the anti-glare cover 22 .

[0048] Preferably, it also includes:

[0049] The first limiting structure 23 acts on the barrel 2 and can limit the barrel 2 from sliding relative to the lamp body 1 in the axial direction.

[0050] In this embodiment, when focusing, the barrel 2 is moved axially relative to the lamp body 1, driving the lens 21 to move axially relative to the light-emitting component 12 until the distance between the lens 21 and the light-emitting component 12 is appropriate, and the first limiting component is used to act on the barrel 2 to keep the current distance between the lens 21 and the light-emitting component 12.

[0051] Preferably, it also includes:

[0052] The second limiting structure 13 acts on the barrel 2 and can limit the barrel 2 from rotating relative to the lamp body 1 in the circumferential direction.

[0054] In this embodiment, when the tensioning screw 231 is turned outward, the resisting force on the bottom wall of the strip groove is cancelled, so that the barrel 2 can slide axially relative to the lamp body 1. In the above state, the inner end of the tensioning screw 231 is still located in the strip groove, which can serve the purpose of sliding guide; when the tensioning screw 231 is turned inward, the inner end of the tensioning screw 231 resists against the bottom wall of the strip groove, thereby limiting the axial sliding of the barrel 2 relative to the lamp body 1. In addition, the inner end of the tensioning screw 231 is always located in the strip groove to limit the rotation of the barrel 2 in the circumferential direction relative to the lamp body 1, so as to ensure that the highest point of the anti-glare cover 22 is always located on the same axis.

[0055] Preferably, a screw cap 233 is provided at the outer end of the tightening screw 231 .

[0056] In this embodiment, the outer peripheral wall of the screw cap 233 is provided with anti-slip stripes to facilitate the user to tighten the loosening screw 231 .

[0057] Preferably, it also includes:

[0058] An assembly plate 14, disposed in the light source cavity 11 and used to support the light emitting assembly 12;

[0059] The light-transmitting plate 15 can cover the light source cavity 11 , and the light-emitting end of the light-emitting component 12 faces the light-transmitting plate 15 .

[0069] One end of the second connection portion 172 is rotatably connected to the first connection portion 171 via the rotating shaft 173 , and the other end is provided with an external thread.

[0070] In this embodiment, the first connecting portion 171 and the second connecting portion 172 that can rotate relatively are used to adjust the direction of the light emitting end of the lamp body 1, thereby meeting more usage requirements.

[0071] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention.
