Description

Technical Field

[0001] The utility model relates to the field of floodlights, in particular to a floodlight with an adjustable light beam diffusion angle. Background Art

[0002] Floodlights are lighting fixtures embedded in the ceiling. They produce concentrated light beams and are widely used in homes, shopping malls and other places. They can be installed on ceilings, windows and other places for decoration or lighting. With the continuous development of lighting technology, floodlights are an important lighting equipment and are widely used in various occasions.

[0003] However, traditional floodlights often have the problem that the beam diffusion angle cannot be adjusted or the adjustment range is limited, which makes it difficult to meet the lighting needs in different scenarios. Therefore, it is particularly important to develop a floodlight that can flexibly adjust the beam diffusion angle. Utility Model Content

[0004] The purpose of the utility model is to provide a floodlight with adjustable light beam diffusion angle to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A floodlight with adjustable beam diffusion angle comprises a base plate, an upper surface of which is fixedly mounted an adjustment mechanism capable of adjusting the irradiation angle, an upper surface of which is fixedly mounted an irradiation mechanism for projecting light, and one side of the irradiation mechanism is provided with a control component for operating the irradiation mechanism.

[0007] Furthermore, the adjustment mechanism includes: a mounting platform, the bottom surface of the mounting platform is fixedly connected to the upper surface of the base plate, two single-sided gear discs are fixedly installed on the upper surface of the mounting platform, a double-sided gear cylinder is meshed and installed between the two single-sided gear discs, a through hole matching the connecting column is opened at the center of the double-sided gear cylinder, and a bracket is fixedly installed on the upper surface of the double-sided gear cylinder.

[0008] Furthermore, an adjustment component for adjusting the beam diffusion angle is arranged inside the irradiation mechanism, and the irradiation mechanism includes: a protective cover, a wire tube is arranged inside the protective cover, an electric lamp body is arranged on one side of the wire tube, and a mounting plate and a fixing plate for mounting the protective cover are arranged on the surface of the wire tube.

[0009] Furthermore, the adjustment assembly includes: four inner diffusion plates, a connecting plate is fixedly installed on one side of the inner diffusion plate, a connecting rod is fixedly installed on the surface of the connecting plate, a rotatable shaft is provided in the middle section of the connecting rod, and one end of the connecting rod is fixedly installed on the side surface of the sliding ring.

[0010] Furthermore, the other side of the sliding ring is fixedly mounted on the output shafts of four electric push rods, one side of the electric push rod is fixedly mounted on a side surface of a fixed disk, and four diffusion outer plates are also fixedly mounted on the outer surface of the wire tube.

[0011] Furthermore, the control assembly includes: a cable, one end of the cable is electrically connected to the lamp body, the other end of the cable is connected to a side surface of the control area, and the outer surface of the cable is sheathed with a protective tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In this scheme, by providing an adjustment component, the beam diffusion angle can be flexibly adjusted. By controlling the extension and retraction of the electric push rod, the sliding ring can be pushed to slide on the lamp tube, thereby driving the connecting rod and the connecting plate to move, so that the inner diffusion plate changes its angle. This design enables the floodlight to adjust the diffusion range of the beam according to different lighting needs and achieve precise control. Whether in areas that require concentrated lighting or places that require extensive lighting, the ideal beam diffusion effect can be achieved by adjusting the component;

By rotating the adjustment knob, the single-sided gear disc and the double-sided gear cylinder can be driven to rotate, thereby changing the direction of the bracket, and then changing the direction of the irradiation mechanism. This design enables the floodlight to easily adjust the irradiation angle to meet the lighting needs of different scenes. Whether it is in a scene where the irradiation direction needs to be changed or the irradiation height needs to be adjusted, it can be achieved through the adjustment mechanism. This flexibility and convenience greatly improves the scope of use and practicality of the floodlight. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the utility model, when in use, the staff installs the floodlight at a desired position through the bottom plate 1 at the bottom thereof, and the bottom plate 1 not only provides a stable installation foundation, but also bears the weight of the entire floodlight;

[0027] The irradiation angle of the floodlight can be flexibly adjusted through the adjustment mechanism.

In addition, four diffusion outer plates 11 are also fixed on the outer surface of the wire tube 18. They work together with the inner diffusion plate 19 to further adjust the diffusion effect of the light beam.

[0029] The control component is responsible for providing power and control functions for the floodlight. The cable 8 connects the lamp body 21 to the control area 5 to ensure power supply.
