Description

Technical Field

[0001] This utility model relates to the field of LED strip technology, and in particular to a COB LED strip with easy heat dissipation. Background Technology

[0002] Currently, COB light strips are used in various aspects of life. As COB light strip technology develops, people have increasingly higher requirements for the brightness and focus of COB light strips. Therefore, high-brightness and high-power LED chips are used to provide light strips with higher brightness. However, these high-brightness and high-power LED chips generate a lot of heat, so the use of these light strips also carries the risk of high temperature and even short circuit. Therefore, a COB light strip with easy heat dissipation is needed.

[0003] This utility model was developed precisely because of the above shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of the prior art and provide a COB light strip that is easy to dissipate heat.

[0010] The connector is provided with two snap-fit ​​grooves, and two flexible bases are provided on both sides of the receiving grooves. The outer side of the mounting base is provided with snap-fit ​​protrusions that can be snapped into the snap-fit ​​grooves. The snap-fit ​​protrusions include two arc-shaped snap-fit ​​parts that are spaced apart vertically. A connecting body is provided between the two snap-fit ​​parts that can be connected to them. The connecting body is provided with two first connecting parts and two second connecting parts that can protrude along its side. The two first connecting parts and two second connecting parts are symmetrically arranged on both sides of the connecting body.

[0011] The outer periphery of the two first connecting parts and the two second connecting parts is arranged in an arc shape, and the arc surface is circular with the arc surface of the arc-shaped snap-fit ​​part.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] like Figures 1 to 6As shown, a heat-dissipating COB LED strip includes: a flexible base 1, a receiving groove 11 with an opening 12 facing downward on the flexible base 1, a plurality of through holes 13 on the surface 100 of the flexible base 1, a flexible substrate 2 disposed in the receiving groove 11, a plurality of LED chips 3 evenly distributed at equal intervals on one side of the flexible substrate 2, an encapsulating colloid 4 disposed on the flexible base 1 to encapsulate the LED chips 3 and the surface 100 of the flexible base 1, a sealing cover 5 connected to the flexible base 1 to close the receiving groove 11, a first heat dissipation component 6 disposed between the sealing cover 5 and the other side of the flexible substrate 2, the first heat dissipation component 6 including a connecting seat 61 disposed on the upper side of the sealing cover 5, a connecting cover 62 connected to the connecting seat 61, a receiving groove 621 disposed on the connecting cover 62, the connecting seat 61 connecting to the connecting cover 62 and covering and sealing the receiving groove 621, and heat dissipation powder 63 disposed in the receiving groove 621.

[0027] When this invention is in use, the heat from the LED chip 3 and the flexible substrate 2 can be conducted through the connecting cover 62 to the heat dissipation powder 63 in the receiving groove 621, where the heat is absorbed by the heat dissipation powder 63. At the same time, the LED chip 3 also dissipates heat to the outside air. Through air heat exchange and heat exchange material heat exchange, the heat dissipation efficiency is improved, and the light strip is prevented from overheating. The flexible base 1 and the sealing cover 5 can protect the LED chip 3 and the flexible substrate 2, which can not only be waterproof, but also be positioned to prevent external damage, thus improving safety.

[0028] The flexible base 1 is connected to a second heat dissipation component 7 at one end. The second heat dissipation component 7 includes a mounting base 71 with a side air vent 711 facing the flexible base 1. A cooling fan 72 is mounted on the mounting base 71. The connecting seat 61 has multiple ventilation slots 611 for airflow from the cooling fan 72. The cooling fan 72 is designed to accelerate airflow, allowing heat to flow through the ventilation slots 611 on the connecting seat 61, resulting in better heat dissipation.

[0029] The flexible base 1 is provided with a positioning frame 8 that can be inserted into the through hole 13. The positioning frame 8 has a positioning space 81 and a reflective surface 82. The positioning frame 8 is used to position the LDE chip 3, which is convenient and accurate. At the same time, the reflective surface 82 can reflect the light source of the LDE chip 3, resulting in better brightness.

[0030] A connecting plate 9 is detachably connected to the flexible substrate 2, and the connecting plate 9 is coated with a light-diffusing layer 91 of phosphor or light-diffusing powder. The light-diffusing layer 91 enables the emitted light to be more uniform.

[0031] The flexible base 1 is provided with two snap-fit ​​grooves 14, which are located on both sides of the receiving groove 11. The mounting base 71 has snap-fit ​​protrusions 712 on its outer side that can snap into the snap-fit ​​grooves 14. Each snap-fit ​​protrusion 712 includes two arc-shaped snap-fit ​​portions 7121 spaced vertically apart. A connecting body 7122 is provided between the two snap-fit ​​portions, allowing them to connect. The connecting body 7122 has two first connecting portions 7123 and two second connecting portions 7124 that protrude along its side. The two first connecting portions 7123 and two second connecting portions 7124 are symmetrically arranged on both sides of the connecting body 7122. The snap-fit ​​protrusions 712 and snap-fit ​​grooves 14 facilitate snap-fit ​​fixing, making the fixing more stable. The two first connecting parts 7123 and the two second connecting parts 7124 can be fixed horizontally, and the two arc-shaped snap-fit ​​parts 7121 and the connecting body 7122 can be fixed vertically, making the fixation more stable.

[0032] The outer periphery of the two first connecting parts 7123 and the two second connecting parts 7124 is arranged in an arc shape, and the arc surface is concentric with the arc surface of the arc-shaped snap-fit ​​part 7121, which facilitates processing and makes the fixing and positioning more stable.

[0033] The sealing cover 5 is also provided with a backstop structure 51, which includes multiple backstop portions 511. The backstop portions 511 can fit against the groove wall of the receiving groove 621 to prevent the first heat dissipation component 6 from sliding when the flexible base is bent.

[0034] The anti-reverse part 511 has a first arc-shaped surface 5111 and a second arc-shaped surface 5112 connected to the first arc-shaped surface 5111, and the endpoints of the first arc-shaped surface 5111 and the second arc-shaped surface 5112 are connected, so that the anti-reverse part 511 is arranged in a rounded arc, so that the anti-reverse part 511 can fit more tightly when it is downward.

[0035] Multiple backstops 511 are symmetrically arranged on both sides of the closed cover 5, and the multiple backstops 511 on the same side are spaced vertically apart, so that a space 512 is formed between two adjacent backstops 511. The space 512 not only allows for ventilation and heat exchange, but also allows the backstops 511 to have sufficient space to move and deform to fit against the groove wall of the receiving groove 621.

[0036] The heat dissipation powder 63 includes carbon-based powder or ceramic powder. The carbon-based powder is graphite powder, etc., which facilitates heat dissipation. The space enclosed by the connecting seat 61 and the connecting cover 62 also facilitates sealing and positioning of the powder, resulting in better heat dissipation.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
