Description

TECHNICAL FIELD

[0001] The utility model relates to the field of LED lighting, in particular to a LED lamp strip with heat dissipation structure. BACKGROUND

[0002] LED lamp strip is widely used in household, commercial and landscape lighting fields because of its energy saving, environmental protection, long service life and other advantages. However, a large amount of heat will be generated when the LED lamp strip works, and if the heat dissipation is poor, it will lead to the decrease of light efficiency of LED lamp beads, the shortening of service life, and even the safety hazard. The heat dissipation structure of the existing LED lamp strip is relatively simple, and usually only relies on the flexible substrate for heat dissipation, so the heat dissipation effect is limited, and it is difficult to meet the heat dissipation demand of high-power LED lamp strip. Therefore, how to design a LED lamp strip with high-efficiency heat dissipation structure has become a technical problem to be solved in the field. SUMMARY

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a LED lamp strip with heat dissipation structure, which has the advantages of optimizing the heat dissipation structure, improving the heat dissipation efficiency, and prolonging the service life of the LED lamp strip.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0005] A LED lamp strip with heat dissipation structure, comprising a flexible substrate, a plurality of LED lamp beads arranged on the flexible substrate, and a transparent protective layer covering the surface of the LED, the back surface of the flexible substrate is provided with a heat dissipation fin, the heat dissipation fin is made of high-thermal-conductivity material, the surface of the heat dissipation fin is provided with a plurality of heat dissipation fins, the heat dissipation fins are uniformly distributed along the length direction of the flexible substrate, and the heat dissipation area is increased; the flexible substrate and the heat dissipation fin are fixed by heat-conducting adhesive; a plurality of heat dissipation holes are arranged on the flexible substrate, the heat dissipation holes penetrate through the flexible substrate and the heat dissipation fin, and the air convection heat dissipation is enhanced; an anti-static component is arranged in the heat dissipation hole, and the static electricity accumulation is prevented.

[0006] By adopting the above technical scheme, the LED lamp beads will generate a certain amount of heat when working. By arranging the heat dissipation fin and the heat dissipation fin, the heat dissipation area is increased, the heat dissipation efficiency is improved, the working temperature of the LED lamp bead is effectively reduced, and the service life of the lamp strip is prolonged. The flexible substrate and the heat dissipation fin are fixed by heat-conducting adhesive, the structure is compact, and the flexibility and installation flexibility of the lamp strip are not affected. The heat dissipation holes are arranged on the flexible substrate and the heat dissipation fin, the air convection heat dissipation effect is enhanced, and the heat dissipation performance is further improved. By arranging the anti-static component in the heat dissipation hole, the static electricity accumulation can be effectively prevented, the LED lamp bead and the circuit are protected, and the service life of the lamp strip is prolonged.

[0007] Further arrangement: the anti-static component includes an anti-static coating applied to the inner side wall of the heat dissipation hole, the anti-static coating is connected with a grounding wire, and the grounding wire extends to the outside of the heat dissipation fin for pouring static electricity into the ground.

[0008] By adopting the above technical scheme, through the design of the anti-static coating and the grounding wire, static electricity can be promptly introduced into the ground, and the safety hazard caused by static electricity can be avoided.

[0009] Further arrangement: the anti-static coating is made of conductive polymer, and the thickness is 0.1mm-0.5mm.

[0010] By adopting the above technical scheme, the coating has good conductivity and wear resistance, can effectively absorb and disperse static electricity, and the anti-static coating needs to be firmly attached to the inner side wall of the heat dissipation hole to prevent the coating from falling off due to external force.

[0011] Further arrangement: the heat dissipation fin is made of aluminum alloy, and the thickness of the heat dissipation fin is 0.5mm-1.5mm.

[0012] By adopting the above technical scheme, the heat dissipation fin made of aluminum alloy has good heat conductivity, can quickly conduct the heat generated by the LED lamp beads from the heat source to the heat dissipation fin, and effectively dissipate the heat to the surrounding air through the surface of the heat dissipation fin, avoiding overheating of the LED light bar, and the design of the thickness of 0.5mm-1.5mm can ensure the heat dissipation performance while providing the mechanical strength of the heat dissipation fin.

[0013] Further arrangement: the surface of the flexible substrate is coated with a waterproof coating.

[0014] By adopting the above technical scheme, by coating the waterproof coating on the surface of the flexible substrate, and by seamlessly connecting with the transparent protective layer, water can be effectively prevented from penetrating, the LED lamp beads and the circuit can be protected, the service life of the light strip can be prolonged, and the light strip remains light, thin and flexible.

[0015] Further arrangement: symmetric mounting grooves are formed on both sides of the heat dissipation fin, and magnetic strips are embedded in the mounting grooves.

[0016] By adopting the above technical scheme, by arranging the magnetic strips on both sides of the heat dissipation fin, the user can fix the light strip on the metal surface by magnetic attraction, and the installation and disassembly are more convenient.

[0017] In summary, the utility model has the following beneficial effects:

[0018] This invention increases the heat dissipation area and improves heat dissipation efficiency by setting heat sinks and heat dissipation fins, effectively reducing the operating temperature of LED beads and extending the life of the light strip. The heat sink and flexible substrate are bonded and fixed with thermally conductive adhesive, resulting in a compact structure that does not affect the flexibility and installation flexibility of the light strip. Heat dissipation holes are set on the flexible substrate and heat sink to enhance the air convection heat dissipation effect and further improve the heat dissipation performance. By setting anti-static components in the heat dissipation holes, static electricity accumulation can be effectively prevented, protecting LED beads and circuits and extending the life of the light strip.

[0019] This invention, through the design of an anti-static coating and a grounding wire, can promptly conduct static electricity to the ground, avoiding safety hazards caused by static electricity.

[0020] This invention effectively prevents moisture infiltration by coating a waterproof layer on the surface of a flexible substrate and seamlessly connecting it with a transparent protective layer, thus protecting the LED beads and circuits, extending the lifespan of the light strip, and maintaining its thinness and flexibility.

[0021] This invention features magnetic strips on both sides of the heat sink, allowing users to magnetically attach the LED strip to a metal surface, making installation and removal more convenient. Attached Figure Description
