Description

Technical Field

[0027] Embodiment 1:

[0028] like Figures 1 to 6 As shown, a spotlight heat sink includes a heat dissipation base 1, a plurality of heat dissipation fins 11 are arranged at intervals on the outside of the heat dissipation base 1, a heat dissipation groove 12 is formed between two adjacent heat dissipation fins 11, an accommodating cavity 13 is opened at the left end of the heat dissipation base 1, and a plurality of heat dissipation channels 14 are also opened thereon, the heat dissipation channel 14 penetrates the heat dissipation base 1 along the lateral direction of the heat dissipation base 1, and the left end thereof is communicated with the accommodating cavity 13.

[0029] The accommodating cavity 13 designed at the left end of the heat dissipation base 1 is intended to accommodate the LED light group. Its design feature is that it can provide sufficient heat dissipation space for the LED light group, effectively accommodating and dispersing the generated heat; at the same time, the accommodating cavity 13 is connected to the outside of the heat dissipation base 1 through the heat dissipation channel 14, and the accumulated heat can be quickly discharged to the external environment. In addition, the synergistic effect of the heat dissipation fins 11 and the heat dissipation grooves 12 further enhances the heat dissipation effect, forming a dual heat dissipation mechanism, effectively preventing heat from accumulating inside the spotlight radiator, and significantly improving the heat dissipation efficiency. This design not only optimizes the heat dissipation performance, but also improves the service life and stability of the spotlight, providing a strong guarantee for the long-term stable operation of the product.

[0030] Furthermore, the heat dissipation channel 14 includes a straight channel 141 on the left, a tapered channel 142 on the right, and a middle narrow channel 143 connected between the straight channel 141 and the tapered channel 142; the right end of the straight channel 141 gradually shrinks from left to right to connect with the left end of the middle narrow channel 143; the left end of the tapered channel 142 is connected to the right end of the middle narrow channel 143, and its right end gradually expands from left to right. The purpose is to form a "Laval" channel, thereby achieving the Laval effect, and then quickly conduct the heat accumulated in the accommodating cavity 13 to the external environment.

[0031] Furthermore, a concave portion 131 which gradually sinks from left to right is provided on the right side of the accommodating cavity 13. The concave portion 131 is hemispherical in shape. The concave portion 131 is conducive to expanding the connection area with the heat dissipation channel 14, so as to facilitate the heat dissipation channel 14 to further accelerate the heat dissipation in the accommodating cavity 113.

[0032] Furthermore, an LED light group connecting position 1311 for connecting the LED light group is provided in the middle of the recess 131, and its purpose is to realize the connection and installation of the LED light group.

[0033] Embodiment 2:

[0034] like Figures 7 and 8 As shown, the difference between this embodiment and embodiment 1 is that:

[0035] The heat dissipation channel 14 includes a small-diameter heat dissipation channel 14a and a large-diameter heat dissipation channel 14b. There are multiple small-diameter heat dissipation channels 14a, and they are arranged outside the large-diameter heat dissipation channel 14b. The structures of the small-diameter heat dissipation channel 14a and the large-diameter heat dissipation channel 14b are the same as the structures of the heat dissipation channel 14 in Example 1, so they are not repeated here. When the large-diameter heat dissipation channel 14b is arranged in the middle of the present application, its purpose is to align it with the LED lamp group installed in the middle position, so as to effectively accelerate the heat dissipated by the LED lamp group to be exported to the external environment.

[0036] The present application also mentions a spotlight, comprising the spotlight heat sink as described in Example 1 or Example 2.

[0037] The above is an implementation method provided in combination with specific content, and it is not considered that the specific implementation of this application is limited to these descriptions. Any similarity or similarity with the method, structure, etc. of this application, or any technical deduction or replacement made on the premise of the concept of this application, shall be deemed to be within the scope of protection of this application.
