The LED chips, the IC control switch, and the current-limiting resistor are sealed on the substrate through the packaging layer, and a part of the two conductive electrodes is exposed outside the packaging layer.
[0004] Adopting the above technical solution, by connecting the IC control switch with the LED chips and the current-limiting resistor and arranging them inside the filament strip, it can cooperate well with automated production equipment, enabling large-scale automated production and improving production efficiency. However, in the above technical solution, connecting the IC control switch with the LED chips and the current-limiting resistor and arranging them inside the filament strip can only improve production efficiency. During the use of the LED lamp, heat is generated and there is a temperature difference with the external environment, which easily causes water vapor in the air to adsorb on the internal components of the LED lamp, resulting in the internal electrical components of the LED lamp being affected by moisture and reducing its service life.
[0005] Therefore, we propose an LED filament strip and an LED lamp to solve the above problems. Summary of the Utility Model

A fluorescent shell is jointly arranged outside the two LED chip bodies, and the bottom surface of the fluorescent shell is fixedly connected to the upper surface of the substrate. Two metal pins are fixedly connected to the front surface of the conductive film. A fixing frame is fixedly connected to the right side surface of each micro heat dissipation fin, and a first activated carbon plate is fixedly connected to the inner wall of each fixing frame. Two first air outlets and two second air outlets are formed on the upper surface of the substrate, and a second activated carbon plate is fixedly connected to the inner wall of each second air outlet.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0024] Refer to Figures 1 - 5, an LED filament strip is proposed, which includes a substrate 1. A protective housing 2 and a conductive film 13 are fixedly connected to the upper surface of the substrate 1. Two micro heat dissipation fins 6 are fixedly connected to the inner wall of the protective housing 2. Two limit frames 7 are fixedly connected to the outer surface of the protective housing 2. The bottom surface of each limit frame 7 is fixedly connected to the upper surface of the substrate 1. Through the limit frames 7, the protective housing 2 and the substrate 1 can be fixed to prevent the position of the protective housing 2 from shifting and becoming unstable.
[0025] Two LED chip bodies 14, two resistor bodies 15 and an LED lamp body 3 are fixedly connected to the upper surface of the conductive film 13. A fluorescent shell 8 is jointly arranged outside the two LED chip bodies 14. Two fixing plates 18 are fixedly connected to the outer surface of each micro heat dissipation fin 6. The right side surface of each group of fixing plates 18 is fixedly connected to the left side surface of the protective housing 2. Through the fixing plates 18, the micro heat dissipation fins 6 and the protective housing 2 can be fixed, enhancing the stability of the device and effectively preventing the problem of its position jittering and shifting.
[0026] The bottom surface of the fluorescent shell 8 is fixedly connected to the upper surface of the substrate 1. Two metal pins 5 are fixedly connected to the front surface of the conductive film 13. Two fixing bolts 19 are threadedly connected to the inner wall of each group of fixing plates 18. The outer surface of each group of fixing bolts 19 is threadedly connected to the inner wall of the protective housing 2. Through the fixing bolts 19, the fixing plates 18 and the protective housing 2 can be fixed, playing a strong reinforcement role and effectively avoiding the problem of shaking during its reuse.
[0027] A fixing frame 9 is fixedly connected to the right side surface of each micro heat dissipation fin 6. A first activated carbon plate 10 is fixedly connected to the inner wall of each fixing frame 9. Two first air outlets 16 and two second air outlets 17 are opened on the upper surface of the substrate 1. A second activated carbon plate 11 is fixedly connected to the inner wall of each second air outlet 17. A reinforcing frame 12 is fixedly connected to the outer surface of each second activated carbon plate 11. The bottom surface of each reinforcing frame 12 is fixedly connected to the upper surface of the substrate 1. Through the reinforcing frame 12, the second activated carbon plate 11 and the substrate 1 can be reinforced, having a strong fixing effect and preventing it from swaying during operation.
[0028] One end of each metal pin 5 far from the conductive film 13 sequentially penetrates through the fluorescent shell 8 and the protective housing 2 and extends to the outside of the protective housing 2. A fixing ring 4 is fixedly connected to the outer surface of each metal pin 5. One end of each fixing ring 4 close to the substrate 1 is fixedly connected to the front surface of the protective housing 2. Through the fixing ring 4, the metal pin 5 and the protective housing 2 can be fixed to prevent the problem of shaking and shifting during their use.
[0029] In this embodiment, an LED filament strip is also proposed, including the above-mentioned LED filament strip.
[0030] The working principle of the present utility model is as follows: When in use, first install the LED chip body 14, the LED lamp body 3, and the resistor body 15 on the conductive film 13. Then, cover the fluorescent shell 8 on the surface of the LED chip body 14, which can convert the blue light emitted by the LED chip body 14 into white light or light of other required colors. Next, perform the encapsulation work, fix the protective housing 2 on the substrate 1 to protect the LED chip body 14, the resistor body 15, the LED lamp body 3, and other internal components. And the protective housing 2 is made of a transparent or translucent resin material. Furthermore, by connecting the metal pins 5 to an external circuit, the LED chip body 14 and the LED lamp body 3 in the device can emit light. When the temperature inside the device is relatively high, the heat is transferred from the heat source to the heat dissipation fins through the micro heat dissipation fins 6, and then the heat is dissipated into the environment to achieve the purpose of cooling and heat dissipation. And through the first air outlet 16 and the second air outlet 17, ventilation and heat dissipation work can be carried out inside the protective housing 2. When the air circulates inside the device, the first activated carbon plate 10 and the second activated carbon plate 11 can absorb the water vapor in the air, playing a strong moisture-proof role, and can effectively avoid the problem that the LED lamp emits heat during use and generates a temperature difference with the external environment, which easily causes the water vapor in the air to adsorb on the internal components of the LED lamp, resulting in the internal electrical components of the LED lamp being affected by moisture and reducing its service life.
