Technical Field
[0001] This utility model relates to the field of floodlight technology, specifically a fixed floodlight. Background Technology
[0002] Floodlights are a type of direct light distribution lighting fixture that achieves high output light intensity within a defined solid angle through the principles of reflection and refraction. They are also known as spotlights, projectors, or floodlights and are widely used in outdoor venues, industrial plants, or building facades.
[0003] Traditional floodlights are fixed to their working position by using mounting holes on a bracket. However, traditional floodlight brackets mostly adopt a rigid one-piece molded structure. Once the floodlight is installed and fixed, the illumination angle is completely locked. If it is necessary to adjust according to the site layout or move the illumination target in actual use, the floodlight needs to be disassembled, adjusted and then fixed again. This is not only cumbersome and time-consuming, but also reduces the practicality of the floodlight. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a fixed floodlight that solves the problem that once the floodlight is installed and fixed, the illumination angle is completely locked. If adjustments are needed based on the site layout or the target being illuminated needs to be moved during actual use, the floodlight must be disassembled and reassembled, which is not only cumbersome and time-consuming, but also reduces the practicality of the floodlight.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed floodlight includes a housing, a lamp plate on the upper part of the housing, lamp beads fixedly connected to the outer wall of the lamp plate, a lens on the upper part of the lamp plate, a bracket on the lower part of the housing, two mounting holes on the lower part of the outer wall of the bracket, and an adjustment assembly between the bracket and the housing, comprising two sets of the adjustment assembly; the adjustment assembly includes a disc, a rotating shaft, threaded holes, and bolts; the disc is fixedly connected to the side wall of the housing, the end of the bracket is fixedly connected to the rotating shaft, the end of the rotating shaft is rotatably connected to the inner wall of the disc via a bearing, the side wall of the disc has several threaded holes, and a bolt is threadedly connected to the end of the bracket near the rotating shaft, the outer wall of the bolt being threadedly connected to the inner wall of the threaded hole.
[0006] Preferably, a second connecting plate is fixedly connected to the outer wall of the lens, and a first connecting plate is fixedly connected to the upper part of the outer wall of the housing, with the top of the first connecting plate fixedly connected to the bottom of the second connecting plate.

[0009] Preferably, a number of reinforcing ribs are fixedly connected between the shell and the first connecting plate.
[0010] Preferably, a limiting component is provided on the outside of the disc body; the limiting component includes a groove and a slider; the groove is opened on the side wall of the disc body near the threaded hole, and the end of the bracket is fixedly connected to the slider on the side near the disc body, and the outer wall of the slider is slidably engaged with the inner wall of the groove. Beneficial effects
[0011] This utility model provides a fixed floodlight. It has the following advantages: This fixed floodlight, through the cooperation of the disc, rotating shaft, threaded holes, and bolts, allows for angle adjustment of the floodlight without disassembling and reassembling it. This solves the problem that once the floodlight is installed and fixed, the illumination angle is completely locked. If adjustments are needed based on the site layout or the target location, the floodlight must be disassembled and reassembled, which is not only cumbersome and time-consuming but also reduces its practicality.
[0012] The cooperation between the slide and the slider provides guidance for the rotation of the housing, avoiding adjustment jamming caused by shaft offset, and limiting the adjustment range. This solves the problem that in the process of adjusting the angle of the floodlight, the lack of an effective guiding structure causes uneven force on the shaft, resulting in offset, which in turn leads to adjustment jamming or increased operating resistance, and even causes accelerated wear of the shaft and bearing, thus shortening the service life of the components.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Once the floodlight is installed and fixed, the illumination angle is completely locked. If it needs to be adjusted according to the site layout or the target needs to be moved during actual use, the floodlight needs to be disassembled and reassembled. This not only makes the operation process cumbersome and time-consuming, but also reduces the practicality of the floodlight.
[0017] In view of this, the present invention provides a fixed floodlight. Through the cooperation between the disc, the rotating shaft, the threaded hole and the bolt, the angle of the floodlight can be adjusted without disassembling and reassembling the floodlight. This solves the problem that when the floodlight is installed and fixed, the illumination angle is completely locked. If it needs to be adjusted according to the site layout or the illumination target needs to be moved in actual use, the floodlight needs to be disassembled and reassembled. This is not only cumbersome and time-consuming, but also reduces the practicality of the floodlight.
[0018] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.
[0019] Example 1, by Figure 1-4As can be seen, a fixed floodlight in this case includes a housing 1, a lamp plate 6 is provided on the upper part of the housing 1, lamp beads 7 are fixedly connected to the outer wall of the lamp plate 6, a lens 5 is provided on the upper part of the lamp plate 6, a bracket 12 is provided on the lower part of the housing 1, and two mounting holes 13 are provided on the lower part of the outer wall of the bracket 12. An adjustment assembly is provided between the bracket 12 and the housing 1, and two sets of adjustment assemblies are provided. The adjustment assembly includes a disc 15, a rotating shaft 14, threaded holes 16 and bolts 17. The disc 15 is fixedly connected to the side wall of the housing 1, the end of the bracket 12 is fixedly connected to the rotating shaft 14, the end of the rotating shaft 14 is rotatably connected to the inner wall of the disc 15 through a bearing, the side wall of the disc 15 is provided with threaded holes 16, and the end of the bracket 12 near the rotating shaft 14 is threadedly connected to the bolt 17, and the outer wall of the bolt 17 is threadedly connected to the inner wall of the threaded hole 16. In the specific implementation process, it is worth noting that the first connecting plate 2 and the housing 1 are integrally die-cast from 6063 aluminum alloy, the lamp plate 6 is made of FR-4 aluminum-based copper-clad plate, the lamp bead 7 is model SMD5050, with a single power of 3W and a color temperature of 6500K, the bracket 12 is made of Q235 steel, the rotating shaft 14 and bolt 17 are made of 304 stainless steel, and the threaded blocks 16 are arranged in an equidistant manner. When installing the projector, the operator moves the housing 1, thereby moving the bracket 12 to the working position, and fixes the bracket 12 to the working position through the mounting hole 13, thereby installing the projector in the working position and completing the fixing of the projector. When the angle of the projector needs to be adjusted, the operator first rotates the bolts 17 on both sides. The bolts 17 rotate in the bracket 12 and are rotated out of the threaded hole 16, releasing the housing 1 from its fixation. Then, the operator rotates the housing 1, which drives the disc 15 to rotate around the pivot 14, thereby rotating the projector to the specified angle. Finally, the operator rotates the bolts 17 in the opposite direction, rotating them into the corresponding threaded hole 16, fixing the position of the housing 1. This allows the angle of the projector to be adjusted without disassembling and reassembling it. Furthermore, a second connecting plate 3 is fixedly connected to the outer wall of the lens 5, and a first connecting plate 2 is fixedly connected to the upper part of the outer wall of the housing 1. The top of the first connecting plate 2 is fixedly connected to the bottom of the second connecting plate 3. In the specific implementation process, it is worth noting that the second connecting plate 3 and the edge of the lens 5 are fixed together with epoxy resin glue, and the two are locked with M4 stainless steel screws. The lens 5 is made of tempered glass. The staff turns the M4 stainless steel screws to fix the first connecting plate 2 and the second connecting plate 3 together, thereby fixing the position of the lens 5. Furthermore, a sealing ring 8 is bonded to the outer wall of the lamp panel 6 on the side close to the lens 5. The outer wall of the sealing ring 8 is attached to the bottom of the lens 5, and the shape of the sealing ring 8 matches the shape of the lamp panel 6. In the specific implementation process, it is worth noting that the sealing ring 8 is made of fluororubber, which has a weather resistance temperature range of -20℃ to 150℃. It can adapt to outdoor high and low temperature and high humidity environments, and avoid aging and cracking after long-term use. When the first connecting plate 2 and the second connecting plate 3 are locked, the sealing ring 8 is evenly compressed to achieve IP65 level waterproof and dustproof sealing, effectively preventing rainwater and dust from entering the area of the lamp board 6 and extending the service life of the lamp bead 7. Furthermore, a battery compartment 9 is provided on the inner wall of the housing 1, and four batteries 10 are snapped into the inner wall of the battery compartment 9. A PG interface 11 is fixedly connected to the front of the housing 1. In the specific implementation process, it is worth noting that the battery compartment 9 is a rectangular cavity integrally die-cast from the shell 1, with an elastic buckle structure on the inner wall, which can realize the quick installation and removal of the battery 10. The battery 10 is an NCR18650B model, with a single battery capacity of 3400mAh and a voltage of 3.7V. The voltage of 4 batteries connected in series is 14.8V. The battery 10 is connected to the lamp board 6 through gold-plated terminals, with a contact resistance of ≤5mΩ, reducing power loss. The PG interface 11 is made of nylon PA66 material, which is compatible with cables with an outer diameter of 8-12mm. After tightening the locking nut of the PG interface 11, the cable and the shell 1 can be sealed with an IP68 level, preventing moisture from entering the interior of the shell 1 along the cable. The four batteries 10 inside the battery compartment 9 supply power to the aluminum substrate lamp plate 6 through gold-plated terminals. The lamp beads 7 emit light when powered on, and the light is concentrated by the high-transmittance tempered glass lens 5. Specifically, by changing the size of the housing 1, the first connecting plate 2, the second connecting plate 3, the lens 5, the lamp board 6, the battery compartment 9, and the bracket 12, the number of lamp beads 7 and batteries 10 is changed, and the number of batteries 10 is set to two, so that the projector becomes a small projector. Furthermore, a number of reinforcing ribs 4 are fixedly connected between the shell 1 and the first connecting plate 2. In the specific implementation process, it is worth noting that the material of the reinforcing rib 4 is the same as that of the shell 1, and it is integrally die-cast with the shell 1. The cross section of the reinforcing rib 4 is triangular and is evenly distributed along the length of the first connecting plate 2. It can not only enhance the connection strength between the first connecting plate 2 and the shell 1, but also increase the heat dissipation area of the shell 1 and assist the heat of the lamp plate 6 to be conducted to the shell.
[0020] Example 2, by Figure 1 and 4It can be seen that a limiting component is provided on the outside of the disc body 15; the limiting component includes a slide groove 18 and a slider 19; the slide groove 18 is opened on the side wall of the disc body 15 near the threaded hole 16, and the end of the bracket 12 is fixedly connected to the slider 19 near the side of the disc body 15, and the outer wall of the slider 19 is slidably engaged with the inner wall of the slide groove 18. In the specific implementation process, it is worth noting that the slider 19 is made of polytetrafluoroethylene, whose low coefficient of friction ensures that the adjustment process is smooth and without jamming. When adjusting the angle of the projection lamp, the disc 15 drives the slide 18 to rotate, and the slide 18 moves along the surface of the slider 19 to guide the rotation of the housing 1, avoid the adjustment jamming caused by the offset of the rotating shaft 14, and limit the adjustment range to prevent excessive rotation from pulling the internal cables.
