[0039] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] Reference Figure 1 、 Figure 4 and Figure 5 The first embodiment of the present application proposes a heat dissipation lamp strip, which includes: a light-emitting module 1, a circuit substrate 2, a copper plate 3 and a fiberboard 4; the light-emitting module 1 is arranged on the circuit substrate 2, and the light-emitting module 1 is electrically connected to the circuit substrate 2; the copper plate 3 is arranged between the circuit substrate 2 and the fiberboard 4.

[0041] The copper plate 3 includes a first copper strip 31, a second copper strip 32, and a connecting diaphragm 33; the first copper strip 31 and the second copper strip 32 are spaced apart and fixed to the two sides of the connecting diaphragm 33; the first copper strip 31 abuts one side of the circuit substrate 2 and is used to electrically connect the positive terminal of the circuit substrate 2 and the positive conductor of the external wire 12, and the second copper strip 32 abuts the other side of the circuit substrate 2 and is used to electrically connect the negative terminal of the circuit substrate 2 and the negative conductor of the external wire 12; the bottom surfaces of the first copper strip 31, the second copper strip 32, and the connecting diaphragm 33 all abut against the fiberboard 4.

[0042] In this embodiment, the copper plate 3 enhances the conductivity between the circuit substrate 2 and the external wires 12, thereby improving the light uniformity of the light-emitting module 1. Furthermore, the first copper tape 31 and the second copper tape 32 enhance the conductivity between the positive and negative terminals of the circuit substrate 2 and the external wires 12, respectively, further improving the light uniformity of the light-emitting module 1.

[0043] The first copper tape 31 and the second copper tape 32 are arranged in parallel at intervals by connecting the diaphragm 33, thereby preventing the first copper tape 31 and the second copper tape 32 from being close to each other, thereby causing the first copper tape 31 and the second copper tape 32 to be electrically connected. It also prevents the first copper tape 31 and the second copper tape 32 from being too far apart, thereby preventing the first copper tape 31 from being unable to electrically connect to the positive terminal of the circuit substrate 2 and the second copper tape 32 from being unable to electrically connect to the negative terminal of the circuit substrate 2, thereby ensuring that the first copper tape 31 and the second copper tape 32 are respectively stably and reliably connected to the positive terminal and the negative terminal of the circuit substrate 2, thereby stabilizing the uniform light effect of the light-emitting module 1; it can also assist in heat dissipation of the copper plate 3 and the circuit substrate 2, and further enhance the heat dissipation effect by setting the first copper tape 31 and the second copper tape 32 at a gap between each other; finally, the fiberboard 4 further assists the heat dissipation of the copper plate 3 and the circuit substrate 2, thereby further enhancing the heat dissipation effect.

[0044] In summary, the heat dissipation light strip of the present invention not only achieves a strong heat dissipation effect inside the light strip, but also enhances the luminous effect of the light strip.

[0045] Specifically, the first copper tape 31 and the second copper tape 32 are electrically connected, that is, the positive terminal and the negative terminal of the circuit substrate 2 are short-circuited.

[0046] Specifically, the connecting diaphragm 33 and the fiberboard 4 are set separately, which can not only realize the gap setting between the first copper belt 31 and the second copper belt 32 and limit the position of the first copper belt 31 and the second copper belt 32, but also facilitate the replacement of the fiberboard 4 to ensure the heat dissipation effect and uniform light effect.

[0047] Specifically, the connecting diaphragm 33 is made of PET, which is relatively hard and can be bent along the axial direction to keep the first copper strip 31 and the second copper strip 32 spaced apart and ensure the bendability of the heat dissipation lamp strip.

[0048] Reference Figure 1 The heat dissipation lamp strip further includes an anti-breaking piece 13 ; the fiberboard 4 is fixed on the anti-breaking piece 13 .

An escape gap 53 is formed between the light emitting module 1 and the wall of the second positioning hole 52 .

[0054] In this embodiment, the lamp housing 5 is used to protect the light-emitting module 1, the circuit substrate 2, the copper plate 3 and the fiberboard 4. Furthermore, the circuit substrate 2, the copper plate 3 and the fiberboard 4 are defined together by the first clearance hole 51, the light-emitting module 1 is placed by the second clearance hole 52, and the avoidance gap 53 is used to prevent the lamp housing 5 from causing damage to the light-emitting module 1 when the lamp housing 5 is subjected to external force.

[0055] Specifically, the lamp housing 5 is made of a transparent visible material, the circuit substrate 2 is an FPC board, and the lamp housing 5 is made of a soft transparent silicone material, so as to facilitate the bendable function of the heat dissipation lamp strip.

[0058] In this embodiment, the first shell 54 is embedded in the first embedding groove 551 to achieve an embedded connection between the first shell 54 and the second shell 55, that is, the first shell 54 and the second shell 55 are detachably connected, which facilitates the disassembly and replacement of the fiberboard 4 to ensure the heat dissipation effect, and also facilitates the replacement of the copper plate 3 to ensure the luminous effect.

[0059] The first housing 54 is embedded in the first embedding groove 551 , and the side groove wall sealing cover of the first embedding groove 551 is arranged under the notch of the clearance groove to achieve the sealing arrangement of the light emitting module 1 , the circuit substrate 2 , the copper plate 3 and the fiberboard 4 .

[0063] In this embodiment, the two ends of the lamp housing 5 are encapsulated by the tail plugs 6. The plugging bases 61 of the two tail plugs 6 define the fitting position of the first shell 54 and the second shell 55 in the axial direction of the light strip. The first extending clamps 62 of the two tail plugs 6 define the fitting position of the first shell 54 and the second shell 55 in the radial direction of the light strip. This achieves a detachable connection between the first shell 54 and the second shell 55 and improves the connection strength between the first shell 54 and the second shell 55.

[0064] Reference Figures 2 to 4 There are three first extension card plates 62 , and the three first extension card plates 62 are connected to each other to form a U-shaped structure.

[0071] In this embodiment, the wire protection head 7 is used to connect the copper plate 3 to the external wire 12, and the outlet position is sealed and protected to prevent the internal light-emitting module 1, circuit substrate 2, copper plate 3 and fiberboard 4 from moisture or contamination, thereby avoiding affecting the conductivity of the copper plate 3 and the heat dissipation effect of the fiberboard 4.

[0072] Specifically, the light emitting module 1 , the circuit substrate 2 , the copper plate 3 , and the external wires 12 are electrically connected in sequence.

[0073] Reference Figure 4 and Figure 6 The heat dissipation light strip further includes a wire plug 9, which includes a first terminal 91, a partitioning rubber section 92, and a second terminal 93.
