Description

Technical Field

[0001] The present application belongs to the technical field of floodlight structures, and in particular relates to an LED floodlight with an integrated housing. Background Art

[0002] A floodlight, also known as a spotlight, is a lamp that provides a higher illuminance on a designated illuminated surface than the surrounding environment. Typically, it can be aimed in any direction and is designed to be unaffected by climatic conditions. It is primarily used in large-scale work areas and mines, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, nearly all large-area outdoor lighting fixtures can be considered floodlights.

[0003] To this end, in a high-power LED floodlight with publication number CN215522982U, a high-power floodlight with high waterproofness and good sealing is provided; the specific structure includes a metal shell, a layout plate is connected to the metal shell, a number of lamp beads are arranged on the layout plate, and light-blocking grids are fixedly provided on the layout plate around the lamp beads. The light-blocking grids are connected to a transparent panel, and the transparent panel is fixedly connected to the metal shell. A number of heat dissipation plates are evenly distributed and fixed on the metal shell, and a waterproof mechanism for connecting wires is provided on the metal shell.

[0004] In the floodlight structure described in the reference document, the layout plate is directly fixed to the housing with screws, merely transferring the heat generated by the lamp beads to the heat sink. In actual operation, heat is generated not only by the lamp beads but also by the components that operate them, and even the entire housing itself. This heat needs to be directed away from the housing, which renders the existing structure unsatisfactory. In the floodlight structure described in the reference document, the heat sink is located outside the metal housing, resulting in a complex, unsightly back shape and a potential safety hazard. Utility Model Content

[0005] The purpose of the utility model is to solve the existing problems and provide a floodlight that can fix lamp beads and electronic components on a heat sink and guide heat to the bottom surface through the heat sink, so that the entire shell can be made into a smooth surface.

[0006] In order to achieve the above technical objectives, the following technical solution is provided: an LED floodlight, comprising a cover base, the cover base having a first opening, the first opening being a placement opening for the LED light on the front side, the cover base being integrally formed with a second opening, the second opening being located on one of the side surfaces adjacent to the first opening, and serving as the bottom surface of the floodlight; a bottom plate having a closed second opening on the bottom surface, the bottom plate being integrally formed with an LED substrate located in the cover base; an LED light located at the first opening being fixed on the front side of the LED substrate; a heat dissipation rib group being integral with the LED substrate on its back side, a component group being fixed behind the heat dissipation rib group; and a plurality of conductive wire groups being provided on the bottom plate for connection with the internal component group.

[0007] In an practicable manner, a fixing mechanism is provided between the second opening and the bottom plate.

[0008] The fixing mechanism includes a fixing base, which is located at the four vertices of the second opening, two of which are connected to the front side as first base blocks, and the remaining two are connected to the back side as base strips penetrating the cover base;

[0009] Bolt holes, wherein the first base block is provided with bolt holes perpendicular to the bottom surface, and the base bar is also provided with bolt holes perpendicular to the bottom surface;

[0010] The bolt rod is set in the bolt hole and is a countersunk bolt.

[0011] In an practicable manner, an auxiliary component for limiting and protecting the LED light is provided in the first opening.

[0012] The auxiliary component includes base blocks located at the four vertices of the first opening, wherein the two base blocks located at the bottom are first base blocks; and the remaining two base blocks located at the top are second base blocks;

[0013] a limiting rod, provided on the first base block and the second base block and pointing to the first opening;

[0014] The decorative plate is sleeved on the limiting rod, and the center thereof is engaged with each LED light bead;

[0015] The glass baffle is glued to the inner side of the first opening and contacts the free end of the limiting rod.

[0016] In an practicable manner, the cover base is provided with connecting legs of a fixing bracket on a pair of side surfaces on both sides of the first opening, and the fixing bracket can pass through the front of the second opening when the connecting legs are rotated to a suitable angle.

[0017] In an practicable manner, the connecting foot is provided with a dial for displaying the rotation angle, and the dial and the connecting foot are matched and fixed to the cover base by countersunk rivets.

[0018] In an practicable manner, a light shield is provided between the cover base and the connecting pin and is sleeved outside the cover base. The light shield has an extension at the first opening. The light shield slides along the first opening when being installed or removed.

[0019] In an practicable manner, the heat dissipation rib group is vertically arranged and includes first heat dissipation ribs located on both sides, and the first heat dissipation ribs are provided with a fixing hole group; the fixing hole group includes at least three first fixing holes, and the first fixing holes are arranged in a row;

[0020] At least two first fixing holes in the fixing hole group are used to fix the circuit board in the component group, and the circuit board has a power module fixed on it; and at least one first fixing hole is used to fix the control board in the component group.

[0021] In an operative manner, the heat dissipation rib group further includes a middle heat dissipation rib located between the first heat dissipation ribs, wherein the middle heat dissipation rib has a plurality of limiting holes for fixing the LED light-emitting panel, and the limiting holes are embedded in the heat dissipation rib group from the front side of the LED substrate.

[0022] In an practicable manner, the bottom plate is further provided with a wire base for connecting, fixing and leading out the conductive wire group, and a through hole for waterproofing and ventilation.

[0023] In an practicable manner, there are three wire bases extending into the heat dissipation rib group; there is one through hole; and the wire bases and the through hole are linearly arranged in the middle of the bottom plate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The heat dissipation rib group is fixed with light-emitting lamp beads and electronic components. When the floodlight is working, the heat of the lamp beads and the heat of the components will be transferred to the heat dissipation rib group, and then transferred from the base plate to the outside of the floodlight, which makes the heat dissipation inside the floodlight more efficient.

[0026] The cover base is designed as an integrated body, one of the openings is a light-emitting opening as the front, and the other opening is an inlet and outlet of the components as the bottom, so that the easily observable surfaces of the floodlight are all smooth, which is more conducive to achieving aesthetics with the design shape, and is different from the problem of only having a heat dissipation strip in the existing technology.

[0027] The baseplate, LED substrate, and heat dissipation ribs are integrally formed, reducing the number of parts required for the floodlight. Installation is simple: simply slide the housing onto the baseplate. No visible bolts are visible on the top, back, or sides. Countersunk rivets are used to secure the few bolts, ensuring a tight fit with the housing.

[0028] In summary, the present application can not only solve the heat dissipation problem, but also ensure that the surface of the outside of the floodlight is smooth, and the entire floodlight is more sealed. Even if rainwater stays on the floodlight, it will not enter the inside of the cover base through the gap on the bottom surface. BRIEF DESCRIPTION OF THE DRAWINGS
