Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, specifically to an LED lamp with antibacterial function. Background Technology

[0002] Ultraviolet (UV) germicidal lamps possess bactericidal and bacteriostatic effects. The principle of UV sterilization is that UV light photocatalyzes nano-semiconductor materials, activating these materials to strongly oxidize organic matter, bacteria, viruses, formaldehyde, TVOCs, etc., in the air, decomposing them into carbon dioxide and water, thus achieving the purpose of sterilization and bacteriostatic effects. However, because UV germicidal lamps can cause the death of growing or regenerating cells, they cannot be used when people are present. Yet, in densely populated environments, without air sterilization and bacteriostatic effects, bacterial infections can easily occur. Existing LED lights are commonly used harmless light sources that only provide illumination and do not possess the function of sterilizing and bacteriostatically inhibiting bacteria in the air without affecting the health of users, resulting in poor functionality. Furthermore, existing LED lights typically use glue or screws to bond the lamp housing and bottom sealing plate together. While this secures the lamp housing and sealing plate, disassembly and replacement are troublesome and time-consuming when the internal LED beads are damaged. Therefore, we propose an LED light with antibacterial function to solve the problems mentioned in the background technology. Summary of the Invention

[0003] The purpose of this invention is to provide an LED light with antibacterial function, which has the advantages of multi-functionality and convenient installation and disassembly, and solves the problems of existing LED lights having single function and inconvenient installation and disassembly.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an LED lamp with antibacterial function, comprising a housing cover, a sealing frame at the bottom of the housing cover, an antibacterial plate snapped onto the top of the sealing frame, the antibacterial plate being made of nano-semiconductor material, an aluminum substrate inside the housing cover, a controller connected to the aluminum substrate by wires and bolted to the top of the housing cover, LED beads welded to the bottom of the aluminum substrate, blue light source and red light source respectively welded inside the LED beads, and phosphor sprayed inside the LED beads, a sliding groove being formed on the surface of the sealing frame, a locking block being provided inside the sliding groove, a return spring being provided between the locking block and the sliding groove, and the locking block cooperating with the housing cover.

[0005] The present invention is further configured such that the top of the shell cover is symmetrically threaded with positioning bolts, and the top of the aluminum substrate is threadedly connected to the positioning bolts via a connector.

[0006] The above technical solution is used to limit the position of the aluminum substrate.

[0007] The present invention is further configured such that the surface of the shell cover is provided with heat dissipation holes, and a dustproof mesh for use with external dust is installed inside the heat dissipation holes.

[0008] The above technical solution facilitates heat dissipation for the LED chips.

[0009] The present invention is further configured such that both ends of the reset spring are bolted with fixing members, and the two fixing members are respectively bolted to the locking block and the sealing frame.

[0010] The above technical solution is adopted to limit the position of the reset spring.

[0011] The present invention is further configured such that a slider is bolted to the bottom of the locking block, and a groove for cooperating with the slider is provided inside the sliding groove.

[0012] The above technical solution is adopted to limit the position of the locking block.

[0013] The present invention is further configured such that a mounting bracket is bolted to the top of the shell cover, and the number of the mounting brackets is two.

[0014] The above technical solution facilitates the installation of the device.

[0015] The present invention is further configured such that the blue light source uses a wavelength of 460nm and the red light source uses a wavelength of 660nm.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention, by installing blue and red light sources inside the LED beads and using a phosphor layer, can obtain a light source with a wavelength of 570nm-590nm that is harmless to the eyes and skin. The light source with a wavelength of 570nm-590nm activates the antibacterial plate, enabling the antibacterial plate to kill and inhibit bacteria in the air, achieving the function of ultraviolet sterilization without harming the human body, thus improving its practicality and benefiting thousands of households.

[0018] This invention features a sliding groove on the sealing frame. With the help of a locking block and a return spring inside the sliding groove, the sealing frame can be locked at the bottom of the cover to limit its position. This eliminates the need for screws or glue, achieving the purpose of installation and improving the speed of installation and disassembly during subsequent maintenance. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1:

[0026] Please see Figure 1 , Figure 2 ,and Figure 3As shown, an LED light with antibacterial function includes a housing 1. Two mounting brackets 18 are bolted to the top of the housing 1 to facilitate installation. Positioning bolts 13 are symmetrically threaded onto the top of the housing 1. The top of an aluminum substrate 4 is threadedly connected to the positioning bolts 13 via a connector to limit the position of the aluminum substrate 4. Heat dissipation holes 14 are provided on the surface of the housing 1, and a dustproof mesh is installed inside the heat dissipation holes 14 to facilitate heat dissipation of the LED beads 6. A sealing frame 2 is provided at the bottom of the housing 1, and an antibacterial plate 3 is snapped onto the top of the sealing frame 2. The antibacterial plate 3 is made of nano-semiconductor material. An aluminum substrate 4 is disposed inside the housing 1, and a controller 5, which is electrically connected to the aluminum substrate 4, is bolted to the top of the housing 1. At the bottom of component 4, LED beads 6 are welded together. Inside LED beads 6, blue light source 7 and red light source 8 are welded together. Blue light source 7 uses a wavelength of 460nm and red light source 8 uses a wavelength of 660nm. Inside LED beads 6, a phosphor layer 9 is sprayed, which is a mixture of red and yellow phosphors. By installing blue light source 7 and red light source 8 inside LED beads 6, and using phosphor layer 9, a light source with a wavelength of 570nm-590nm that is harmless to the eyes and skin can be obtained. The light source with a wavelength of 570nm-590nm activates the antibacterial plate 3, enabling the antibacterial plate 3 to kill and inhibit bacteria in the air, achieving the function of ultraviolet sterilization without harming the human body, thus improving its practicality and benefiting thousands of households.

[0027] Brief description of usage: Two wavelength light sources, red light source 8 and blue light source 7, are integrated on an LED bead 6. A phosphor layer 9, composed of a mixture of red and yellow phosphors, ultimately emits light with a color temperature between 3000-5500K. Exciting the yellow phosphor in phosphor layer 9 with the 460nm blue light source 7 produces cool white light. Using the 660nm red light source 8 in combination with the phosphor excited by the 460nm blue light source 7 makes the spectrum appear less violet, achieving an effect similar to decorative white light, but with the spectral components including red and blue light, fixing the dominant wavelength at 560K. The light emitted at -600nm continuously irradiates the antibacterial plate 3 made of nano-semiconductor material. This excites the activity of the nano-semiconductor material, causing electrons to be excited from the valence band to the conduction band, leaving holes. As a result, oxidation and reduction reactions occur on the surface of the antibacterial plate 3. The holes have high reactivity and react with water or hydroxide ions adsorbed on the surface to form highly oxidizing hydroxyl radicals, which are active oxygen. Electrons react with oxygen in the air to generate superoxide ions, which in turn generate hydroxyl radicals. These radicals strongly oxidize organic matter, bacteria, viruses, formaldehyde, TVOC, etc. in the air and decompose them into carbon dioxide and water, thus achieving the purpose of sterilization and bacteriostasis.

[0028] Example 2:

[0029] Please see Figure 1 , Figure 2 and Figure 4 As shown, an LED light with antibacterial function has a sliding groove 10 on the surface of the sealing frame 2. A locking block 11 is provided inside the sliding groove 10. A slider 16 is bolted to the bottom of the locking block 11. A sliding groove 17 is provided inside the sliding groove 10 to cooperate with the slider 16 and limit the locking block 11. A return spring 12 is provided between the locking block 11 and the sliding groove 10. Both ends of the return spring 12 are bolted with fixing parts 15. The two fixing parts 15 are respectively bolted to the locking block 11 and the sealing frame 2 to limit the return spring 12. The locking block 11 cooperates with the shell cover 1. By using the sliding groove 10 on the sealing frame 2, and cooperating with the locking block 11 and the return spring 12 inside the sliding groove 10, the sealing frame 2 can be locked at the bottom of the shell cover 1 to limit the sealing frame 2, so that screws or glue are not used, thus achieving the purpose of installation and improving the speed of installation and disassembly during subsequent maintenance.

[0030] Brief description of the usage process: When installation is required, simply attach the sealing plate to the bottom of the cover 1. Under the action of the return spring 12, the locking block 11 will lock onto the bottom of the cover 1 at the vertical edge connecting the strip. After installation, the locking block 11 will lock the sealing frame 2, thereby limiting the sealing frame 2. When disassembling, simply move the locking block 11 in the opposite direction to make the sealing frame 2 and the cover 1 lose their limiting ability, thus removing the sealing frame 2.
