Aluminum alloy shell, light and simple, beautiful and generous; high-power transformer, perfectly combined with the lamp power supply, further highlights its elegant characteristics.

[0003] An existing radiator for an LED spotlight may specifically refer to application number: CN201120180415.3, which includes a radiator body, wherein the radiator body is provided with recessed holes for placing electrical components, and the surface of the radiator body is provided with heat sinks, which are distributed along the circumferential direction of the radiator body. Since the heat sinks are provided on the surface of the radiator body, when the utility model is applied to the LED spotlight, the heat generated by the LED spotlight can be quickly dissipated through the heat sink, thereby extending the service life of the LED spotlight.

[0004] The above device does not provide the heat sink fin seat with components that can be easily installed and removed, so it is difficult to install or remove and is not easy to operate, resulting in a long installation and removal process and reduced work efficiency. Utility Model Content

[0005] The utility model aims to solve the deficiencies of the prior art and provide a heat sink for an LED spotlight so as to facilitate installation and removal.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a heat sink for an LED spotlight, comprising an outer body of the spotlight, a heat dissipation fin seat is arranged at the rear end of the outer body of the spotlight, and a mechanism for easy removal and installation is arranged on the outer side of the outer body of the spotlight.

[0009] Preferably, second fixing blocks are arranged on both sides of one end of the outer body of the spotlight close to the heat dissipation fin seat, and the side end of the outer body of the spotlight is fixedly connected to the bottom end of the second fixing block, a first slot is opened at the top of the second fixing block, the other end of the first plug block is inserted into the first slot, and the first plug block is slidably connected to the first slot.

[0010] Preferably, the first fixed block has sliding grooves on both sides, the first plug-in block has sliding blocks on both sides of one end, the side end of the first plug-in block is fixedly connected to the rear end of the sliding block, the front end of the sliding block is inserted into the second slot, and the sliding block is slidably connected to the second slot.

[0011] Preferably, second plug blocks are provided on both sides of the front end of the heat dissipation fin seat, and the front end of the heat dissipation fin seat is fixedly connected to the rear end of the second plug block, and second slots are opened on both sides of the rear end of the outer body of the spotlight, the front end of the second plug block is inserted inside the second slot, and the second plug block is slidably connected to the second slot.

[0012] Preferably, a plurality of groups of heat dissipation fin bodies are arranged outside the outer body of the spotlight, and the side end of the outer body of the spotlight is fixedly connected to the bottom end of the heat dissipation fin body.

[0013] Preferably, a plurality of heat dissipation holes are provided on both sides of the outer body of the spotlight, and the outer side of the outer body of the spotlight is fixedly connected to the bottom end of the dust cover near the heat dissipation holes.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The existing device does not have a component that can be easily installed and removed on the heat sink fin seat, which makes it difficult to install or remove and is not easy to operate, resulting in a long time spent in the installation and removal process, reducing work efficiency. Therefore, the design of an easy-to-remove installation mechanism improves the convenience of removal and installation.

[0016] 2. The existing LED spotlight body is not provided with a heat dissipation component on the outside, so the heat can only be dissipated through the heat dissipation seat at the rear, resulting in a slow heat dissipation effect. Therefore, the heat dissipation effect can be increased by cooperating with multiple sets of heat dissipation components. BRIEF DESCRIPTION OF THE DRAWINGS
