Utility model content

The purpose of the utility model is to provide a heat dissipation shell with simple and reasonable structure, flexible operation, good heat dissipation effect and a downlight containing the heat dissipation shell, so as to overcome the deficiencies in the prior art.

A heat dissipation housing designed according to this purpose includes a mounting seat, and its structural feature is that it also includes a heat dissipation seat connected to the mounting seat. The bottom of the heat dissipation seat is provided with a heat dissipation hole and a heat dissipation fin extending outward. The heat dissipation hole clip It is located between two adjacent heat sinks.

Further, a hollow upper cover is provided on the mounting base, and the light-condensing sheet is arranged in the middle of the upper cover.

Further, the inner side of the upper cover is also provided with assembly threads.

Further, more than two positioning posts are provided on the mounting base, and positioning holes for inserting the positioning posts are provided at the bottom of the upper cover.

Further, more than two assembly slots are provided on the outside of the mounting seat.

Further, the bottom of the mounting seat is provided with more than two assembly stubs.

Further, more than two vent holes are provided on the bottom of the mounting base, and the vent holes are located inside the area where the short column is assembled.

Further, more than two heat insulating ribs are provided on the bottom of the mounting seat, and the heat insulating ribs are arranged vertically or obliquely.

Furthermore, a downlight includes a heat dissipation housing, and its structural feature is that it also includes an LED lamp, and the LED lamp is arranged in the mounting seat.

The utility model is provided with heat dissipation holes and outwardly extending heat dissipation fins at the bottom of the heat dissipation seat. The heat dissipation holes are sandwiched between two adjacent heat dissipation fins, which enlarges the heat dissipation area, improves the heat dissipation effect, and reduces the heat dissipation of the heat dissipation shell. surface temperature during operation.

The utility model is provided with more than two positioning columns on the mounting base, and the bottom of the upper cover is provided with positioning holes for inserting the positioning columns, and the assembly between the upper cover and the mounting base is quick.

The utility model is provided with more than two assembling stubs at the bottom of the mounting seat, and the LED lamp can be directly installed in the mounting seat, thereby reducing the assembly strength.

The utility model has the characteristics of simple and reasonable structure, flexible operation and good heat dissipation effect.
