Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1-3 This utility model provides an LED light strip that can switch between sterilization and lighting, the LED light strip comprising:

[0030] A flexible circuit board, wherein pads 8 are provided on the flexible circuit board;

[0031] LED white light bulb 6, the LED white light bulb 6 is mounted on the pad 8 of the flexible circuit board, and is used to convert electrical energy into visible light to realize the lighting function;

[0032] The UVC and UVA dual-in-one lamp bead 5 is mounted on the pad 8 of the flexible circuit board and is used to convert electrical energy into ultraviolet light to achieve sterilization function.

[0033] The circuit design of the LED white light bead 6 and the UVC and UVA two-in-one bead 5 is designed to be independently connected to a power source, so as to realize arbitrary switching between lighting and sterilization functions.

[0034] This application achieves arbitrary switching between lighting and sterilization functions by mounting a UVC and UVA dual-in-one lamp bead 5 and an LED white light lamp bead 6 onto the same flexible circuit board. The light strip, which can meet both lighting and sterilization needs, saves space, reduces total cost, and improves installation efficiency. It can well meet market demand and is suitable for lighting and sterilization needs in scenarios such as home, medical and cold chain transportation.

[0035] In one embodiment of this utility model, please refer to Figures 1-3 The flexible circuit board is provided with a circuit layer 2 and an insulating layer 3;

[0036] Among them, the insulation layer 3 is made of PI material or PET material, and the circuit layer 2 is made of copper foil, copper-aluminum composite material or aluminum foil.

[0037] The pad 8 is formed by exposing the circuit layer 2 through the cover film 1 by drilling or die cutting, wherein the cover film 1 is made of PI or PET material;

[0038] Furthermore, the pad 8 includes LED lamp bead pads, resistor pads, wiring pads, and UVC and UVA dual-function lamp bead pads.

[0039] The LED lamp bead pad 8 is connected to the LED white light lamp bead 6, and the LED white light lamp bead 6 is connected to DC power to convert electrical energy into light energy, so as to play a lighting role.

[0040] It also includes: a resistor 7, which is mounted on the resistor pad and connected in series with the LED white light bead 6 and the UVC and UVA dual-in-one bead 5, for controlling the current and protecting the bead.

[0041] Resistor 7 is used to control the current and protect the LED white light bead 6 and the UVC and UVA combined bead 5 from the impact of large current. The UVC and UVA combined bead 5 is connected in series with resistor 7. After being connected to DC power, it emits short-wave ultraviolet light and long-wave ultraviolet light to disinfect bacteria and destroy the DNA or RNA molecular structure of microorganisms.

[0042] In one embodiment of this utility model, please refer to Figures 1-3 The flexible circuit board has double-sided adhesive 4 attached to its back for fixing the light strip to an external solid surface, such as an aluminum profile.

[0043] The double-sided adhesive 4 uses double-sided acrylic adhesive, fiberglass thermal conductive adhesive, or aluminum adhesive.

[0044] Please see Figures 1-3The circuit design of the LED white light bulb 6 and the UVC / UVA combined bulb 5 is either a common anode design or a reverse design. In the common anode design, the circuit of the LED white light bulb 6 shares the positive terminal with the circuit of the UVC / UVA combined bulb 5, but each has its own separate negative terminal. In the reverse design, the positive terminal of the LED white light bulb 6 circuit is also the negative terminal of the circuit of the UVC / UVA combined bulb 5, and vice versa. An external controller enables the individual or simultaneous activation of the lighting and sterilization functions.

[0045] There are multiple UVC and UVA dual-in-one lamp beads 5, which are evenly distributed on the flexible circuit board and are alternately mounted with the LED white light lamp beads 6.

[0046] The UVC and UVA dual-in-one lamp bead 5 emits ultraviolet light with wavelengths of 270nm (UVC) and 400nm (UVA).

[0047] In the process of using the light strip, firstly, the flexible circuit board uses flexible copper foil to form a circuit layer 2 through etching or die cutting. A PI film is laminated at the bottom of the circuit layer 2 as an insulating layer 3. An insulating PI film with solder pads 8 is laminated on the top of the circuit layer 2 as a cover film 1. The cover film 1 is made of PI or PET material and exposes the circuit layer 2 to form solder pads 8 through drilling or die cutting. The circuit layer 2 is made of metal copper foil, copper-aluminum composite material or aluminum foil material and forms circuits through etching or die cutting. The insulating layer 3 is made of PI or PET material and laminated to the back of the circuit layer 2 for insulation and protection.

[0048] Secondly, the LED white light bulb 6 is soldered to the circuit layer 2 via the solder pads 8 on the flexible circuit board using metal tin. The LED white light bulb 6 is used to convert electrical energy into visible white light. The UVC and UVA combined bulb 5 is also soldered to the circuit layer 2 via the solder pads 8 on the flexible circuit board using metal tin.

[0049] Therefore, by mounting the UVC and UVA combined LED bead 5 and the LED white light bead 6 onto the same flexible circuit board, and using a three-wire common anode circuit design, there are three solder pads 8. An external controller can be used to control the LED white light bead 6 to light up individually, or the UVC and UVA combined LED bead 5 to light up individually, or simultaneously. With a two-wire reverse design, the controller can control the LED white light bead 6 to light up individually, or the UVC and UVA combined LED bead 5 to light up individually. By sharing a circuit board for both lighting and germicidal LEDs, a shared power supply and controller are achieved, reducing the overall product cost by approximately 30% in terms of insulation layer. Furthermore, the light source assembly process only requires one assembly, significantly improving efficiency and reducing labor costs.

[0050] In summary, this utility model mounts LED white light beads 6 and UVC and UVA band LED purple light beads onto the same circuit board; the LED white light part uses a series resistor 7 to form a complete circuit design, while the UVC and UVA beads are packaged as a single integrated LED; the UVC and UVA integrated LED beads 5 are evenly distributed on the circuit board and are alternately mounted with the LED white light beads 6; the UVC and UVA integrated LED beads 5 are connected in series with the resistor 7 to form a complete circuit design; the circuit design of the LED white light beads 6 and the UVC and UVA integrated LED beads 5 can be independently connected to a power supply, illuminating the LED white light when lighting is needed, and illuminating the UVC and UVA integrated LED beads 5 when sterilization is needed; the density of the UVC and UVA integrated LED beads 5 can be adjusted according to the actual application requirements for the degree of sterilization, and by combining lighting and sterilization functions into one light strip, lighting and sterilization can be switched arbitrarily through the same light strip.
