The first overlapping plate 24 and the first plate 141 are arranged at intervals, and the second sealing groove 242 and the second overflowing glue groove 224 can pass through the gap between the first overlapping plate 24 and the first plate 141 and the third sealing groove. 262 connectivity. Therefore, the glue overflowing from the first glue sealing groove 144 and the first glue overflow groove 145 can communicate with the third glue sealing groove 262 through the second glue overflow groove 224 .

During the assembly process, firstly, glue is applied in the third sealing groove 262 , so as to snap and seal the end cover 20 and the heat dissipation housing 10 to form the assembly cavity 110 . Subsequently, glue is applied in the first glue groove 144 and the second glue groove 242 to seal and fix the cover plate 40 . If there is too much glue in the third sealing groove 262, the overflowing glue will flow into the second sealing groove 242, if there are more glues in the first sealing groove 144 and the second sealing groove 242, then the excess Part of the glue will flow into the first glue overflow groove 145 and the second glue overflow groove 224 , and part of it will flow into the third glue sealing groove 262 to enhance the connection between the second bonding plate 26 and the heat dissipation housing 10 . Therefore, by arranging the first sealing groove 144, the second sealing groove 242, the third sealing groove 262, the first overflowing groove 145 and the second overflowing groove 224 which communicate with each other, not only can the excess glue be avoided from exposing the cover The plate 40 and the heat dissipation housing 10 can also save the amount of glue used, so that the connection between the end cover 20 and the heat dissipation housing 10 is more stable and the sealing effect is better.

Further, as shown in FIG. 2 and FIG. 4 , the floodlight 100 also includes a power supply assembly 50 and a light source assembly 60 , the power supply assembly 50 is assembled in the power assembly groove 112 , and the light source assembly 60 is assembled in the light source assembly assembly groove 114 . In the embodiment of the present invention, the power supply assembly 50 is arranged inside the assembly cavity 110 , which can reduce the damage of the external environment to the power supply assembly 50 , thereby protecting the power supply assembly 50 and prolonging the service life of the power supply assembly 50 .

Different from the prior art, the present invention provides a floodlight 100 on the one hand, by setting end caps 20 on opposite sides of the heat dissipation housing 10, and setting a first positioning part on the surface of the end caps 20 facing the assembly cavity 110 21. The second positioning part 31 is provided on the reflector 30. When the reflector 30 is placed in the assembly cavity 110, the second positioning part 31 is positioned and matched with the first positioning part 21, thereby limiting the reflector 30 in relation to the outgoing light. The movement in the two directions perpendicular to the outgoing direction, when the cover plate 40 of the floodlight 100 is covered on the assembly cavity 110, the cover plate 40 will abut the reflector 30, thereby limiting the reflector 30 in the emission of the emitted light. direction, and then fix the reflector 30 in the assembly cavity 110 , thereby improving the disassembly efficiency of the reflector 30 . On the other hand, the present invention also provides a heat dissipation housing 10. By forming a first glue overflow groove 145 on the side of the first glue sealing groove 144, when the cover plate 40 is covered on the first plate 141, from the first The excess glue overflowing from the sealing groove 144 will enter the first overflowing glue groove 145 and be blocked by the third plate 143, so that the surface of the cover plate 40 will not be exposed, which not only makes the appearance of the floodlight 100 more beautiful, It can also avoid the need to set up a separate station to clean up the overflowing glue, thereby reducing the production complexity of the floodlight 100 and speeding up production efficiency.

The above is only the embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process conversion made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technologies fields, all of which are equally included in the scope of patent protection of the present invention.
