It utilizes the combination of electrons and holes in semiconductor materials to release energy, causing the energy band (Energy Gat,) level to change, and emitting light to display the released energy; LEDs have the advantages of small size, long lifespan, low driving voltage, low power consumption, fast response rate, good shock resistance, etc., and are widely used in signal indication, digital display and other fields; with the continuous progress of technology, the development of ultra-high brightness LEDs has been successful, especially the successful development of white LEDs, making it more and more used in colored light decoration and even lighting fields.

[0003] In the technical solution of an LED floodlight heat dissipation profile with the publication number CN206496285U, a hollow rib tube is used to enhance heat dissipation, and in order to enhance heat dissipation, the mounting bracket is directly installed on the heat dissipation profile. In this regard, the applicant believes that the heat dissipation profile is arranged outside the LED floodlight, resulting in an overall shape that cannot form a beautiful appearance; and it will also pose a safety hazard, and the edges and corners of its heat dissipation ribs will scratch the operator. Utility Model Content

[0004] The purpose of the present utility model is to provide a heat dissipation component for a floodlight in view of the problem that the existing heat dissipation ribs are arranged outside the floodlight, resulting in an unbeautiful shape of the entire outer shell of the floodlight and the resulting safety problems.

[0005] In order to achieve the above technical purpose, the following technical solution is now provided. A heat dissipation component for a floodlight includes a heat dissipation substrate and a heat dissipation rib group arranged on the heat dissipation substrate. An integrally formed bottom plate is provided at the same end of the heat dissipation substrate and the heat dissipation rib group; wherein, the bottom plate has an inner surface located inside the floodlight and an outer surface located outside the floodlight, and the heat dissipation substrate is vertically arranged on the inner surface of the bottom plate.

[0006] In an implementable manner, the heat dissipation rib group is vertically arranged and includes first heat dissipation ribs respectively located on both sides, and fixing hole groups for fixing the circuit board are arranged on the first heat dissipation ribs.

[0007] In an implementable manner, the bottom plate includes fixing holes for fixing that penetrate the bottom plate, a wire base located on the inner surface for connecting, fixing and leading out wires, and through holes for waterproofing and ventilation.

[0008] In an implementable manner, there are four fixing holes, which are respectively located at the four vertices of the bottom plate, and countersunk rivets are fitted in the fixing holes.

[0009] In an implementable manner, there are three wire bases, which extend into the heat dissipation rib group; there is one through hole; the wire bases and the through hole are linearly arranged in the middle of the bottom plate on the side of the heat dissipation rib group.

[0010] In an implementable manner, the fixing hole group includes at least three first fixing holes, and the first fixing holes are arranged in a column.

[0011] In an implementable manner, the heat dissipation substrate includes a back surface provided with a heat dissipation rib group and a front surface opposite to the back surface; wherein, a plurality of limiting holes for fixing the LED light-emitting board are provided on the front surface, and the limiting holes extend into the heat dissipation rib group.

[0012] The utility model has the following beneficial effects compared with the prior art:

[0013] The heat dissipation profile can be arranged inside the lamp housing of the floodlight, and the bottom plate integrally formed with the heat dissipation substrate and the heat dissipation rib group can be used as the bottom plate of the floodlight, so that the overall appearance can be ensured to be beautiful and smooth, without sharp corners causing potential safety hazards; moreover, the heat of the three-person profile can be directly conducted to the bottom plate for cooling, so the present application takes into account the beauty of the overall appearance of the floodlight while having heat dissipation.

[0014] The fixing holes, the wire bases and the through holes are all arranged on the bottom plate, so that a series of connecting parts are all on the bottom surface that consumers don't pay much attention to, ensuring the beauty of the overall appearance; even the fixing holes are designed in the shape for installing countersunk rivets, further ensuring the integrity of the overall appearance.

[0015] The heat dissipation ribs separate the LED light-emitting board and the circuit board, but can dissipate heat from both at the same time, making the overall heat dissipation structure safe and efficient in heat dissipation. Description of the Drawings
