[0043] Embodiment

[0044] Reference Figures 1-3 The embodiment provides a lamp strip which comprises a shell, a substrate 2, LED lamp beads 3, a heat transfer plate 4 and radiating fins 5.

[0045] The shell comprises a lower seat 11 and a transparent upper cover 12. The lower seat 11 is provided with a stepped connecting groove at an opening thereof, and the transparent upper cover 12 is provided with a protrusion 121 at an opening thereof. The lower seat 11 and the transparent upper cover 12 are connected through the connecting groove and the protrusion 121, and are fixed and waterproofed by applying sealing glue at a connecting gap between the lower seat 11 and the transparent upper cover 12 after the connection.

[0046] The transparent upper cover 12 is made of plastic.

[0047] The lower seat 11 is provided with long-strip-shaped radiating holes 111 at a lower side thereof. The lower seat 11 is also made of plastic.

[0048] The substrate 2 is fixed by being pressed and combined together by the connecting groove of the lower seat 11 and the protrusion 121 of the transparent upper cover 12, and is provided with a plurality of through holes 21.

[0049] The LED lamp beads 3 are arranged on an upper side of the substrate 2.

[0050] The heat transfer 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 heat transfer plate 4 is provided with an extension part 41 at a top thereof for contacting the substrate 2, and the extension part 41 is horizontally extended so that a larger contact area is formed between the extension part 41 and the lower side of the substrate 2. Heat-conducting silica gel is arranged between the extension part 41 and the substrate 2.

[0051] The radiating fins 5 are horizontally arranged between the radiating holes 111 and the substrate 2. A gap between the radiating fins 5 and the lower seat 11 is coated with sealing glue. One end of the radiating fins 5 is connected with a side of the heat transfer plate 4, and the other end extends out of the lower seat 11, so that hot air is not easy to flow back, and the radiating effect is better. The radiating fins 5 and the radiating holes 111 both have a radiating effect.

[0052] The inner wall of the lower seat 11, the substrate 2 and the heat transfer plate 4 jointly define a space to form a relatively closed radiating chamber 13. The radiating chamber 13 is communicated with an inside of the transparent upper cover 12 through the through holes 21, and is communicated with an outside environment through the radiating holes 111. The radiating fins 5 are vertically spaced and staggered arranged, so as to form a meandering gas path 14 in the radiating chamber 13. The gas path 14 prolongs the path of the gas and has a plurality of turns, and can block dust and water from entering the transparent upper cover 12. Blocking the dust from entering the transparent upper cover 12 can ensure the lighting and radiating effects. Blocking the water from entering the transparent upper cover 12 can ensure the normal use of the LED lamp beads 3.

[0053] The water is prevented from entering the transparent upper cover 12 in that if water drops enter the lower seat 11 through the heat dissipation holes 111, firstly, it is difficult for the water drops to "climb up" or "flow down" into the transparent upper cover 12 through the winding air path 14 and the through hole 21, and secondly, when the LED lamp beads 3 are working, the heat in the shell is dissipated outward through the through hole 21, the air path 14 and the heat dissipation holes 111, and the water drops that "climb up" or "flow down" are easily dried by the hot air. "Climb up" refers to the movement process of the water drops in the state shown in Figure 1 "Flow down" refers to the movement process of the water drops when the lamp strip is installed in an inverted manner. Figure 1

[0054] In other embodiments, a plurality of heat dissipation fins 5 are arranged in vertical intervals, and the holes are arranged in a staggered manner on the heat dissipation fins 5, and the winding air path 14 described above can also be formed.

[0055] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications, and the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other without conflict. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.​
