The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference Figure 1 As shown in FIG. 1 , an improved light strip 1000 with good heat dissipation according to an embodiment of the present invention is shown, comprising a mounting housing 100, an aluminum substrate 200, a heat dissipation structure 300 and a heat conducting layer 400. Figure 1 and Figure 2As shown, the mounting shell 100 has a mounting cavity 110, the side wall of the mounting cavity 110 is provided with a supporting structure, the bottom of the mounting shell 100 is provided with a heat dissipation hole 120, the aluminum substrate 200 is provided with a plurality of groups of LED lamp beads 210, the aluminum substrate 200 is arranged in the mounting cavity 110, the aluminum substrate 200 is connected to the supporting structure, the aluminum substrate 200 divides the mounting cavity 110 into a light-emitting cavity 111 and a heat-dissipating cavity 112, the light-emitting cavity 111 and the heat-dissipating cavity 112 are respectively located on both sides of the aluminum substrate 200, the LED lamp beads 210 are located in the light-emitting cavity 111, and the heat-dissipating hole 120 is connected to the heat-dissipating cavity 112. The heat dissipation structure 300 is disposed in the heat dissipation cavity 112. The heat dissipation structure 300 includes a connection portion 310 and a plurality of heat dissipation fin portions 320. The connection portion 310 connects the plurality of heat dissipation fin portions 320. The heat dissipation fin portions 320 extend along the length direction of the mounting housing 100. The plurality of heat dissipation fin portions 320 are arranged at intervals along the width direction of the mounting housing 100. The length direction of the mounting housing 100 is the front-to-back direction, and the width direction of the mounting housing 100 is the left-to-right direction. A heat dissipation channel 330 is formed between two adjacent heat dissipation fin portions 320. The heat dissipation channel 330 is connected to the heat dissipation hole 120. The heat conductive layer 400 is located between the aluminum substrate 200 and the heat dissipation structure 300. The heat conductive layer 400 is used to conduct the heat of the aluminum substrate 200 to the heat dissipation structure 300.

[0030] In this embodiment, a support structure is provided, and the support structure can suspend the aluminum substrate 200, so that the contact area between the aluminum substrate 200 and the mounting shell 100 is small, thereby preventing the mounting shell 100 from hindering heat dissipation. By providing a heat dissipation structure 300 and a heat conductive layer 400, the heat conductive layer 400 conducts the heat of the aluminum substrate 200 to the heat dissipation structure 300. The multiple heat sinks 320 of the heat dissipation structure 300 can absorb heat and quickly dissipate the heat. The hot air can flow to the heat dissipation holes 120 through the heat dissipation flow channels 330 and be discharged to the outside through the heat dissipation holes 120, thereby improving the heat dissipation effect of the aluminum substrate 200, so that the heat generated by the LED lamp beads 210 can be quickly conducted to the outside, thereby protecting the LED lamp beads 210.

[0031] Reference Figure 1As shown, according to some embodiments of the utility model, the mounting shell 100 is made of plastic material, and the support structure is arranged on the opposite side walls of the mounting cavity 110. The support structure includes a first boss 130 and a second boss 140 that are spaced apart. The first boss 130 is located above the second boss 140.

The contact area between the aluminum substrate 200 and the first boss 130 and the second boss 140 is small, thereby avoiding poor heat dissipation. During installation, the aluminum substrate 200 can be directly inserted from the side, and the installation operation is convenient. In addition, when installing the heat dissipation structure 300, the heat dissipation structure 300 can be directly pushed into the heat dissipation cavity 112 from the side, and the installation operation is convenient.

The waterproof performance can be improved, even if the external water enters the heat dissipation cavity 112 from the heat dissipation hole 120, the external water will not enter the light emitting cavity 111 due to the barrier of the glue and silicone layer. The end cap 500 also has a sealing function.

[0033] Reference Figure 2 As shown, according to some embodiments of the present invention, the extension direction of the heat dissipation hole 120 is perpendicular to the length direction of the mounting shell 100, and the extension direction of the heat dissipation hole 120 is the left-right direction, so that the extension direction of the heat dissipation hole 120 is staggered with the extension direction of the heat sink portion 320, which can avoid the heat sink portion 320 passing through the heat dissipation hole 120. Specifically, the heat dissipation hole 120 can be a waist-shaped hole, which is more convenient to manufacture.
