[0049] The embodiments of the present application will be described in detail below.

[0050] Embodiment 1

[0051] Referring to Figures 1-3 , the present embodiment provides a lamp strip with good heat dissipation effect, comprising a shell, a substrate 2, an LED lamp bead 3, a heat transfer plate 4 and a heat sink 5.

[0052] The shell comprises a lower seat 11 and a transparent upper cover 12, and the lower seat 11 has a stepped connecting groove at the opening, and the transparent upper cover 12 has a protrusion 121 matched with the connecting groove. The lower seat 11 and the transparent upper cover 12 are connected by the connecting groove and the protrusion 121, and after being connected, sealing glue is applied at the connecting gap of the lower seat 11 and the transparent upper cover 12 for fixation and waterproofing.

[0053] The transparent upper cover 12 is made of plastic material.

[0054] The lower part of the lower seat 11 has a long strip-shaped heat dissipation hole 111. The lower seat 11 is also made of plastic material.

[0055] The four peripheral edges of the substrate 2 are fixedly connected by the connecting groove of the lower seat 11 and the protrusion 121 of the transparent upper cover 12, and the substrate 2 is provided with a plurality of through holes 21.

[0056] The LED lamp beads 3 are arranged on the upper side of the substrate 2.

[0057] The heat-conducting plate 4 is vertically arranged in the lower seat 11 and is located below the substrate 2 and can conduct heat with the substrate 2. The top of the heat-conducting plate 4 has an extension 41 for contacting the substrate 2, and the extension 41 is horizontally extended to have a larger contact area between the extension 41 and the lower side of the substrate 2. The extension 41 and the substrate 2 are provided with heat-conducting silica gel.

[0058] The heat-dissipating fins 5 are horizontally arranged between the heat-dissipating holes 111 and the substrate 2. The gap between the heat-dissipating fins 5 and the lower seat 11 is filled with sealing glue. One end of the heat-dissipating fins 5 is connected to the side of the heat-conducting plate 4, and the other end extends out of the lower seat 11, so that the hot air is not easy to flow back, and the heat-dissipating effect is better. The heat-dissipating fins 5 and the heat-dissipating holes 111 both have heat-dissipating effects.

[0059] The inner wall of the lower seat 11, the substrate 2 and the heat-conducting plate 4 jointly define a space to form a relatively closed heat-dissipating chamber 13, which is in communication with the inside of the transparent upper cover 12 through the through holes 21 and in communication with the outside environment through the heat-dissipating holes 111. The plurality of heat-dissipating fins 5 are vertically spaced and staggered to form a meandering air path 14 in the heat-dissipating chamber 13. The air path 14 prolongs the path of the gas and has multiple turns, which can block dust and water from entering the transparent upper cover 12. Blocking dust from entering the transparent upper cover 12 can ensure the lighting and heat-dissipating effects. Blocking water from entering the transparent upper cover 12 can ensure the normal use of the LED lamp beads 3.

[0060] The blocking of water from entering the transparent upper cover 12 is embodied in that if water droplets enter the lower seat 11 from the heat-dissipating holes 111, firstly, it is difficult for them to "climb up" / "flow down" into the transparent upper cover 12 through the meandering air path 14 and the through holes 21, and secondly, when the LED lamp beads 3 are working, the heat in the shell is dissipated outward through the through holes 21, the air path 14 and the heat-dissipating holes 111, and the "climbing up" / "flowing down" water droplets are easy to be dried by the hot air. Figure 1 "climbing up" refers to the movement process of the water droplets in the state shown in Figure 1 "flowing down" refers to the movement process of the water droplets when the lamp strip is installed in an inverted manner.

[0061] In other embodiments, the plurality of heat-dissipating fins 5 are vertically aligned and arranged with staggered holes on each heat-dissipating fin 5, which can also form the above-mentioned meandering air path 14.

[0062] Embodiment 2

[0063] Referring to Figures 1-3In the embodiment, the heat dissipation holes 111 extend to the bottom of the lower seat 11; the lamp strip with good heat dissipation effect further comprises a support plate 6, the support plate 6 is connected to the bottom of the lower seat 11, and a vertical spacing is left between the support plate 6 and the bottom of the lower seat 11 to form a flow promoting channel 7; in this way, when the external airflow flows through the relatively narrow flow promoting channel 7, the flow rate is accelerated, which can promote the discharge of hot air in the heat dissipation holes 111, and the heat dissipation effect is better.

[0064] In addition, the support plate 6 can be fixed at a specified position to facilitate the installation of the lamp strip with good heat dissipation effect in the Figure 1 position shown in the figure.

[0065] In the embodiment, the support plate 6 is provided with a pad 61, and the pad 61 is connected to the bottom of the lower seat 11 to facilitate the formation of the flow promoting channel 7. The pad 61 is provided with a sliding rail 62, and the bottom of the lower seat 11 is provided with a sliding groove 15 matched with the sliding rail 62, so as to facilitate the connection between the support plate 6 and the lower seat 11.

[0066] Embodiment 3

[0067] In the embodiment, the lamp strip with good heat dissipation effect is installed in the Figure 4 position shown in the figure, that is, in a hoisting manner; the edges of the support plate 6 are slightly bent to better block water and dust.

[0068] Finally, it should be noted that: the above is only a preferred embodiment of the present application and is not used to limit the present application.
