Based on this, an efficient heat dissipation structure for LED light sources is proposed. Utility Model Content

[0025] Embodiment 1:

[0026] Reference Figure 1-Figure 5 A highly efficient heat dissipation structure for an LED light source, wherein a back plate 32 is fixedly connected to one side of a keel 31, and a detachable lamp panel 1 is connected to the back plate 32; a plurality of heat conducting plates 33 are fixed to the other side of the back plate 32, and the other end of the heat conducting plates 33 is connected to a bottom plate 34; an air duct 27, an air inlet duct 22 and an air outlet duct 23 are respectively connected to the support frame 21; a heat dissipation fan 26 is fixedly connected to the outer wall of the air duct 27.

[0027] In the utility model, the keel 31 is composed of a transverse keel 31 and a longitudinal keel 31, so as to increase the supporting force of the support frame 21. The keel 31 and the support frame 21 are fixed and installed by bolts, and the keels 31 can be spliced, so as to cope with support frames 21 of different sizes.

[0028] The heat conducting sheet 33 is fixed on the back plate 32 , which can not only effectively conduct the heat received by the back plate 32 , but also limit the position of the keel 31 during installation, thereby facilitating the positioning and installation of the keel 31 .

[0029] The upper and lower ends of the air inlet duct 22 and the air outlet duct 23 are both designed to be open, so as to meet the needs of the cooling fan 26 for high-power operation and avoid the phenomenon of excessive wind pressure inside the air duct causing noise and damage to the equipment due to insufficient air outlets.

[0030] A certain distance is left between the back of the cooling fan 26 and the air inlet duct 22 , so that air can flow into the air guide duct 27 from the back of the cooling fan 26 .

[0031] Embodiment 2:

[0032] Reference Figure 1-Figure 5 , which is basically the same as Example 1, and further, a plurality of air guide grooves 311 are provided on the vertical keel 31, and the height of the air guide grooves 311 is the same as the spacing between the heat conducting plates 33, a wire management hole 25 is provided on the back plate 32, and the wire management hole 25 passes through the heat conducting plates 33 and the bottom plate 34, a detachable power supply fixing frame 24 is fixedly connected to the keel 31, the air outlet 23 is connected to the bottom plate 34, and the air guide 27 is connected to the bottom plate 34, and filters 221 are provided at the ports on both sides of the air inlet duct 22, and air outlets 29 are provided at the positions of the air guide duct 27 corresponding to the cooling fan 26, and a plurality of positioning blocks 28 are fixed to the support frame 21.

[0033] In the utility model, a plurality of small air ducts are formed by a plurality of heat conducting plates 33 and air guide grooves 311, which further enhance the wind guiding capability and the area in contact with the air.

[0034] Air is continuously input into the air duct 27 through the cooling fan 26. After being squeezed, the air is discharged to the air outlet ducts 23 on both sides through the small air duct composed of the back plate 32, the keel 31, the bottom plate 34 and the heat conducting plate 33. During this process, due to the high pressure inside the air duct 27, the air flow direction will not change and the flow rate will not be reduced.

The power supply fixing frame 24 is cross-shaped, so that multiple power supplies can be fixed.

[0036] A filter 221 is provided at the port of the air supply port 29, which can effectively filter out dust in the air and prevent dust accumulation from causing poor internal heat dissipation. The filter 221 is installed on the support frame 21 by screw positioning, thereby facilitating subsequent regular cleaning of the inside of the pipeline and replacement of the filter 221.

[0037] The bottom plate 34 is fixed to the back plate 32 by screws, so as to facilitate the later disassembly for cleaning and maintenance of the internal pipeline lines.

[0038] The positioning block 28 is used to fix the support frame 21 to a wall or a bracket.
