[0002] An LED light is a solid-state semiconductor device that converts electrical energy into visible light. It is made by curing silver glue or white glue onto a bracket, then connecting the chip and circuit board with silver wire or gold wire, and sealing it with epoxy resin on all sides.

[0003] The existing utility model with authorization announcement number CN208271890U discloses a flexible LED filament light strip, including one or more LED filaments for emitting light and a colorful and translucent flexible packaging layer. The one or more LED filaments are connected in series or parallel. The LED filament includes a flexible substrate for transmitting electrical energy, one or more LED chips for emitting light, and fluorescent glue. The flexible substrate is provided with lamp bead mounting positions corresponding to the number of LED chips. The LED chips are arranged on the lamp bead mounting positions, and the fluorescent glue is coated on the flexible substrate and the periphery of the LED chips.

[0004] The above technical solution is adopted by using a flexible substrate as a carrier board for the LED filament, setting the LED chip on the flexible substrate, and surrounding the flexible substrate and the LED chip with a layer of fluorescent glue to form an LED filament to achieve the effect of emitting light of different colors. However, the above technical solution can only make the LED filament emit light of a specific color through the fluorescent glue, and the LED filament will generate more heat when working for a long time, and the generated heat cannot be effectively cooled, which easily leads to the problem of reduced service life of the LED filament.

[0005] To this end, we propose a flexible LED filament strip to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that LED filaments generate a lot of heat when working for a long time, and the generated heat cannot be effectively cooled, which easily leads to a reduction in the service life of the LED filament. A flexible LED filament strip is proposed.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] Preferably, four limiting plates are fixedly connected to the outer surface of the transparent protective shell, and the bottom surface of each group of limiting plates is fixedly connected to the upper surface of the flexible substrate.

[0010] Preferably, four thread grooves are formed on the upper surface of the flexible substrate, the inner wall of each set of the limiting plates is threadedly connected with two fixing bolts, and the outer surface of each set of the fixing bolts contacts the inner wall of the thread groove.

[0011] Preferably, a fixing ring is fixedly connected to the outer surface of each metal pin, and one end of each fixing ring close to the flexible substrate is fixedly connected to the front surface of the transparent protective shell.

[0012] Preferably, the outer surface of each group of the fixed outer shells is fixedly connected with four reinforcement frames, and the side surfaces of each group of the reinforcement frames that are away from each other are fixedly connected to the inner wall of the transparent protective shell.

[0013] Preferably, the inner wall of each group of the reinforcement frames is threadedly connected with eight fastening bolts, and the outer surface of each group of the fastening bolts is threadedly connected to the inner wall of the transparent protective shell.

[0014] In summary, the technical effects and advantages of this application are:

[0015] 1. The flexible substrate, the first slot, and the second slot cooperate with each other to facilitate the position restriction of the chip body and the resistor body, achieving the purpose of fixed limit and enhancing the stability of the device.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 5 A flexible LED filament strip includes a flexible substrate 1, a transparent protective shell 2 is fixedly connected to the upper surface of the flexible substrate 1, three first slots 13 and three second slots 14 are opened on the upper surface of the flexible substrate 1, and four limiting plates 4 are fixedly connected to the outer surface of the transparent protective shell 2. The bottom surface of each set of limiting plates 4 is fixedly connected to the upper surface of the flexible substrate 1. The limiting plates 4 can fix the transparent protective shell 2 and the flexible substrate 1, thereby enhancing the stability of the device and preventing its position from shifting.

[0025] The inner wall of each first card slot 13 is fixedly connected to the chip body 11, and the inner wall of each second card slot 14 is fixedly connected to the resistor body 12. Four threaded grooves 9 are provided on the upper surface of the flexible substrate 1. The inner wall of each set of limiting plates 4 is threadedly connected to two fixing bolts 5. The outer surface of each set of fixing bolts 5 is in contact with the inner wall of the threaded groove 9. The fixing bolts 5 can fix the limiting plates 4 and the flexible substrate 1, which has a strong reinforcement effect and prevents the problem of displacement and instability during use.

[0026] Four micro heat sink fins 3 are provided inside the transparent protective shell 2. The outer surface of each group of micro heat sink fins 3 is fixedly connected to two fixed shells 15. The outer surface of each group of fixed shells 15 is fixedly connected to four reinforcement frames 16. The side faces of each group of reinforcement frames 16 that are away from each other are fixedly connected to the inner wall of the transparent protective shell 2. The reinforcement frames 16 can reinforce the fixed shells 15 and the transparent protective shell 2, effectively preventing their positions from shifting during operation.

[0027] The outer surfaces of the three chip bodies 11 and the outer surfaces of the three resistor bodies 12 are fixedly connected with a conductive film 10. The inner wall of each group of reinforcement frames 16 is threaded with eight fastening bolts 17. The outer surface of each group of fastening bolts 17 is threaded with the inner wall of the transparent protective shell 2. The fastening bolts 17 can fix the reinforcement frame 16 and the transparent protective shell 2 to avoid the problem of jitter and displacement of their positions.

[0028] Two metal pins 7 are fixedly connected to the front of the conductive film 10, and a fluorescent shell 8 is provided above the conductive film 10. The outer surface of each metal pin 7 is fixedly connected to a fixing ring 6, and the end of each fixing ring 6 close to the flexible substrate 1 is fixedly connected to the front of the transparent protective shell 2. The fixing ring 6 can fix the metal pin 7 and the transparent protective shell 2 to prevent them from shaking and deviating during use.

[0029] The working principle of the present invention is as follows: when in use, the chip body 11 and the resistor body 12 are first installed in the first card slot 13 and the second card slot 14 on the flexible substrate 1 respectively, and then the fluorescent shell 8 is covered on the surface of the chip body 11, which can convert the blue light emitted by the chip body 11 into white light or other required color light, and then it is packaged, and the transparent protective shell 2 is fixed on the flexible substrate 1 to protect the chip body 11 and the resistor body 12 and other internal components. The transparent protective shell 2 is usually a transparent or translucent resin material, and then the metal pin 7 is connected to the external circuit, so that the flexible LED filament strip can emit bright light. When the internal temperature is high due to long-term work, the heat is transferred from the heat source to the heat sink fins through the micro heat sink fins 3, and then the heat is dissipated to the environment, thereby achieving the purpose of cooling and heat dissipation, enhancing the use effect of the device, and effectively avoiding the problem that the LED filament strip generates more heat when working for a long time and cannot effectively cool the generated heat, resulting in a reduced service life of the LED filament strip.
