[0002] Flexible light strips are slender, bendable, brightly colored lighting devices that consist of multiple small energy-saving light-emitting diodes (LEDs). Flexible light strips have uniform and continuous lighting effects, and because of their excellent corrosion resistance, weather resistance, and high protection performance, they can be widely used both indoors and outdoors. Therefore, flexible light strips are widely used in various outdoor building lighting projects, scenic spot landmark outlines, indoor space art decorations, advertising signs, holiday decorations, and commercial entertainment venue atmosphere decorations.

[0003] In order to reduce the thickness of the flexible light strip, a flexible circuit board is usually used to install the LED lamp. However, the flexible circuit board is very thin and is easy to break when pulled by external force. In order to protect the flexible light strip, it is usually used together with a protective shell. The thickness of the protective shell is thick, which will cause the flexible light strip to lose its ultra-thin characteristics. In addition, since the LED lamp is welded on the copper foil of the flexible circuit board, the copper foil is very thin. When the light strip is bent, the lamp pins of the LED are easily forced to fall off, causing a dead light phenomenon. Therefore, an ultra-thin flexible light strip is proposed to solve the above problems. Utility Model Content

[0007] As a further technical solution of the utility model, a flat soft shell is installed on a side of the flexible circuit board away from the flexible soft pad, and the flat soft shell is covered on the flexible circuit board.

[0008] As a further technical solution of the utility model, the flexible soft pad includes a thermally conductive silicone pad, and a plurality of strip grooves are opened on the side of the flexible soft pad away from the flexible circuit board.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-5 As shown, an ultra-thin flexible light strip comprises a flexible circuit board 1 and a plurality of LED lamps 2 equidistantly installed on the flexible circuit board 1. In this embodiment, an electrical component (not shown) for controlling the LED lamps 2 is also arranged on the flexible circuit board 1. A flexible soft pad 3 is installed on the side of the flexible circuit board 1 away from the LED lamp 2 to facilitate protection of the flexible circuit board 1. The flexible soft pad 3 comprises a thermally conductive silicone pad, which not only facilitates heat conduction and improves the heat dissipation effect of the flexible light strip, but also has good insulation and shock absorption properties, which is beneficial to improving the protection effect of the flexible circuit board 1. The flexible soft pad 3 is arranged along the length direction of the flexible circuit board 1.

[0023] A plurality of flexible metal strips 4 are installed on the flexible pad 3. The flexible metal strips 4 have good tensile strength, so that when the flexible light strip is pulled by external force, the flexible metal strips 4 are not easily stretched along the length direction of the light strip, so that the flexible light strip is not easy to cause the flexible circuit board 1 to break when pulled by external force. In addition, the thermal conductivity of the flexible metal strips 4 is utilized to conveniently absorb the heat on the flexible pad 3 and improve the heat dissipation effect of the flexible light strip. A plurality of strip grooves 8 are provided on the side of the flexible pad 3 away from the flexible circuit board 1. The flexible metal strips 4 are fixedly installed in the strip grooves 8, and the flexible metal strips 4 are flush with the notches of the strip grooves 8. The strip grooves 8 are utilized to facilitate the inlay installation of the flexible metal strips 4 on the flexible pad 3.

[0024] A protective member 5 is installed on one side of the flexible circuit board 1 close to the LED lamp 2. The protective member 5 covers the LED lamp 2 to facilitate protection of the LED lamp 2. The protective member 5 includes a ceramic block 501 and a light-transmitting cover plate 502. The ceramic block 501 is fixedly connected to the flexible circuit board 1, and a rectangular through groove 6 is penetrated through the center of the ceramic block 501. The LED lamp 2 is located in the rectangular through groove 6. The light-transmitting cover plate 502 is encapsulated at the notch position of the rectangular through groove 6, which is convenient for protecting the LED lamp 2 and avoiding the use of a traditional thick protective shell, so that the flexible light strip can achieve ultra-thin characteristics. The ceramic block 501 includes a magnesium oxide ceramic block. The magnesium oxide ceramic block has good insulation and thermal conductivity, which is convenient for improving the heat dissipation effect of the light strip.

[0025] A flat soft shell 7 is installed on the side of the flexible circuit board 1 away from the flexible soft pad 3. The flat soft shell 7 is covered on the flexible circuit board 1, so as to provide covering protection for the side of the flexible circuit board 1 away from the flexible soft pad 3. The side of the flat soft shell 7 close to the flexible soft pad 3 is open, and a plurality of rectangular openings 9 are provided on the top of the flat soft shell 7. The rectangular openings 9 correspond to the positions of the ceramic block 501, and the side of the ceramic block 501 away from the flexible circuit board 1 is flush with the top of the flat soft shell 7, so as to facilitate the contact between the ceramic block 501 and the external environment, thereby dissipating heat to the external environment. A plurality of evenly distributed heat dissipation grooves 10 are provided on the side of the ceramic block 501 away from the flexible circuit board 1, so as to effectively increase the heat dissipation area of ​​the ceramic block 501 and improve the heat dissipation efficiency. The plurality of heat dissipation grooves 10 are distributed circumferentially along the rectangular through groove 6.

[0026] The working principle of the utility model is as follows: the bottom of the flexible circuit board 1 is covered and protected by the flexible soft pad 3, and the flexible metal strips 4 are used together, which will not affect the flexibility of the light strip, and the flexible metal strips 4 have good tensile strength, so that the flexible light strip is not easy to cause the flexible circuit board 1 to break when being pulled by external force. At the same time, the flexible soft pad 3 is convenient for conducting the heat generated by the flexible circuit board 1, and the high thermal conductivity of the flexible metal strips 4 is convenient for improving the heat dissipation effect. The ceramic block 501 is provided with a rectangular through groove 6, so that the LED lamp 2 on the flexible circuit board 1 can be enclosed, and the light-transmitting cover is used for packaging, so as to protect the LED lamp 2, avoid the traditional thick protective shell, and make the flexible light strip achieve ultra-thin characteristics. Since the ceramic block 501 is not only insulated, but also has strong hardness, the hard ceramic block 501 is installed on the flexible circuit board 1, so that no matter how the light strip is bent, the part of the flexible circuit board 1 corresponding to the ceramic block 501 will not be bent by force, so that the lamp foot of the LED lamp 2 at this place will not fall off due to the bending of the flexible circuit board 1, which is conducive to improving the service life of the LED lamp 2.
