The heat sink fixing plate 133 is connected to the power supply fixing plate 22.

[0022] This utility model discloses a top-mounted plant lighting lamp, mainly comprising a lamp body 1 and a power supply body 2. The lamp body 1 mainly includes a lamp plate 11, a heat sink 12, and a heat sink fixing frame 13. The lamp plate 11 is equipped with multiple LED beads and is fixed to the bottom of the heat sink 12 by screws. A plastic wire cover is also provided at one corner of the lamp plate 11 to cover the soldering wires, serving both protective and aesthetic purposes. The heat sink 12 is a finned heat sink, which is the main part of the lamp fixture. It not only serves as a structural connection but also dissipates heat from the lamp plate 11. The fins on the back of the heat sink 12 have a large heat dissipation area, resulting in good heat dissipation. Furthermore, numerous ventilation holes are provided on the fins to create "turbulence" and "flow," further enhancing heat convection. The left and right sides of the heat sink 12 are connected to the heat sink cover plate 132 and the heat sink fixing plate 133, respectively, while the front and rear sides are connected to the side plates 131. The bottom of the side plates 131 is fixed to the heat sink 12 with screws, and the upper parts of the heat sink cover plate 132 and the heat sink fixing plate 133 are also fixed to the side plates 131 with screws, thereby enhancing the sturdiness of the heat sink fixing frame 13. The side plates 131 are folded inwards to cover the heat sink cover plate 132 and the heat sink fixing plate 133, concealing their edges. This not only serves an aesthetic purpose but also protects the user from touching the sharp edges of the heat sink fins. The side plates 131 have multiple slots 134 for easy heat dissipation. After the lamp body is installed, the two ends of the hooks 3 are hooked into the slots 134, making it easy to hang the lamp body 1 on the crossbeam 4.

[0023] When in use, after the lamp body is powered on, the lamp beads emit light and shine on the plants. At the same time, the lamp beads also generate a lot of heat. This heat is transferred to the air through the heat sink 12 and its heat sink fins to achieve the heat dissipation effect.
