Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a radiator with a replaceable radiator core and a lamp. Background Art

[0002] Lamp heat sink is a device used to help dissipate heat, usually used in the design and manufacture of various lamps. Its function is to help the heat in the lamp dissipate quickly through effective heat dissipation design, ensure the normal operating temperature of the lamp, and extend the service life of the lamp.

[0003] The invention of the existing application number CN201810353270.9 discloses a lamp radiator, including a radiator body and a fan. The radiator body includes a base and two heat sink groups. The bottom of the heat sink group is connected to the top of the base. The fan is located between the two heat sink groups. The radiator body can use the airflow on both sides of the fan, and the airflow blown by the fan can pass through the heat sink group after a short distance, which is conducive to quickly blowing away the heat, achieving the purpose of rapid cooling, and reducing the power and load of the fan. In addition, the fan is located between the two heat sink groups, which can reduce the distance between the radiator body and the mounting surface, reduce the installation space of the radiator body, and facilitate the installation arrangement of the present invention. Since the radiator is an integrated structure, the size is fixed and it can only be adapted to fixed-size surface-mounted outer ring lamps. In the existing field, the radiator core cannot be disassembled and assembled in a split manner to adapt to the composition of radiators of various sizes, which also brings great inconvenience to replacement and maintenance.

The fast disassembly and assembly of the radiator outer ring 1 and the radiator core 2 can be achieved by means of the buckle 11. Of course, the shape of the radiator outer ring 1 is not limited to a disc shape, but can also be other polygonal shapes.

[0024] In another embodiment, a lamp is provided, including the above embodiment, wherein the lamp further includes a face ring 3 , a reflective cup 4 , a lens 5 , a surface-mounted outer ring 6 and a heat sink core cover 7 .
