[0044] According to one embodiment of the present invention, the insect-repellent and antibacterial composition may further include Picardin.

[0045] The aforementioned Picardin, also known as Icardin, is an environmentally friendly raw material certified by the World Health Organization (WHO).

[0046] By further adding Picardine to the insect-repellent and antibacterial composition, not only can excellent antibacterial and deodorizing effects be maintained, but the attraction of insects and the like can also be significantly inhibited.

[0047] According to one embodiment of the present invention, the insect-repellent and antibacterial composition may further include 0.01 to 10 parts by weight of Picardine relative to 100 parts by weight of water, but is not limited thereto.

[0048] The prepared insect-repellent and antibacterial composition is not limited to the type of substrate to which it can be coated, and can be specifically coated on walls, ceilings, floors, fabrics, and lighting fixtures, etc.

[0049] In particular, when the insect-repellent and antibacterial composition is coated onto a lighting device, the light emitted by the lighting device can be used to repel insects and other potentially attracted insects.

[0050] The lighting device specifically includes a light source, which can be direct lighting (direct illumination) or indirect lighting (indirect illumination) through reflected light from an external light source. It is not limited to illuminating a specific area, and can include existing lighting modules, lighting fixtures, and various lighting devices. Specific examples include LED lighting, fluorescent lamps, incandescent lamps, ceiling lights, downlights, spotlights, searchlights, horizontal lights, multi-lamp chandeliers, floor lamps, chandeliers, full-lighting systems, wall lamps, kitchen lights, living room lights, flat edge lights, square room lights, round room lights, cross lights, strip lights, square sensor lights, round sensor lights, round ceiling lights, oval ceiling lights, underground lighting, parking lot lighting, FPL fluorescent lamps (Fluorescent Parallel Lamps), PL luminaires (Parallel Lamps), short bulbs, long bulbs, single-room push-button lights, square push-button lights, cross lights, long floor lamps, ambient lights, factory lights, and desk floor lamps. The following are examples of lighting fixtures that can be used for purposes such as insect-repellent and antibacterial lighting: slim panel lights, bathroom lights, sink lights, shoe cabinet lights, flat panel edge lights, flat panel slim frame lights, square floodlights, signal lights, sensor lights, ceiling lights, recessed floodlights, advertising lights, flat panel lights, panel lights, marine floodlights, landscape lights, factory floodlights, tunnel lights, waterproof panel lights, emergency downlights, gas station LED lighting, guide lights, emergency lighting, high temperature and high humidity environment lighting, emergency flat panel lights, sports lighting, floodlights and landscape lighting, parking lot lights, moisture-proof lights, parking lights, safety street lights, pedestrian crossing floodlights, courtyard lights, safety lights, tree lighting, and car headlights.

[0051] According to one embodiment of the present invention, the LED lighting fixture can be any one of bulb type, tube type, street lamp type or floodlight type.

[0052] According to one embodiment of the present invention, an insect-repellent and antibacterial lighting fixture can be provided by coating the LED lighting fixture with the insect-repellent and antibacterial composition. By coating the LED lighting fixture with the insect-repellent and antibacterial composition, not only can antibacterial and deodorizing effects be achieved, but also the attraction of insects and other organisms to light can be suppressed.

[0053] According to one embodiment of the present invention, the color temperature range of the LED lighting fixture can be from 2000K to 6000K, specifically from 2000K to 3000K. When the color temperature of the LED lighting fixture is below 3000K, it can emit yellow light; when the color temperature is above 3000K, it can emit white light.

[0054] When the color temperature range is 2000K to 3000K, the number of insects attracted by the light emitted by the LED can be further suppressed.

[0055] According to one embodiment of the present invention, by using LED lighting that satisfies the above-mentioned color temperature range and has a wavelength range of 510 to 700 nm, the number of insects attracted by light can be significantly suppressed.

[0056] Figure 4 shows a table of wavelength ranges for insect-repellent and antibacterial lighting, wavelength ranges for ordinary commercially available LED lighting, and blue light removal rates.

[0057] In existing LED lighting, light with a wavelength range of 300nm to 700nm is typically used. However, in order to effectively suppress the attraction of insects, this invention can shield light in the 300 to 500nm band. Specifically, LED lighting with a wavelength range of 510 to 700nm can be used.

[0058] Excellent insect repellency can be achieved by using LED lighting with a wavelength range of 510 to 700 nm. In particular, the antibacterial, deodorizing and insect repellency effects can be further enhanced when the insect-repellent and antibacterial composition is coated on the LED lighting with wavelength range.

[0059] The LED manufacturing process specifically includes steps such as Epi (epitaxy) wafer manufacturing, chip production, packaging, and modularization. The Epi wafer can be a SiC substrate, but is not limited to it.

[0060] In addition, another embodiment of the LED manufacturing process may include a packaging process, wherein the packaging process includes steps of connecting the manufactured chip with leads and packaging it to emit light outward as much as possible, and steps of using the packaged LED to mount it onto a module on a specific frame, but is not limited thereto.

[0061] Furthermore, in this invention, to achieve blue light or blue light blocking LEDs in the 300 to 500 nm wavelength band, LEDs can be used as excitation light sources, and YAG (Yttrium Aluminum Garnet) fluorescent materials that emit yellow light (510 to 700 nm) can be used on the excitation light source. However, this is only one example, and any method that can remove light in the 300 to 500 nm wavelength band is not limited.

[0062] In particular, according to one embodiment of the present invention, by coating the antibacterial composition onto an LED lamp, not only can an insect-repellent effect be achieved, but a photocatalytic effect can also be produced. The photocatalytic effect refers to the effect of reducing atmospheric pollutants such as NOx and SOx into water and carbon dioxide, but is not limited to general photocatalytic effects.

[0063] The present invention will be further illustrated below by way of examples and comparative examples. However, it should be understood that the examples and comparative examples are only for further illustration of the present invention and are not intended to limit the present invention, which is not limited thereto.

[0064] [Deodorization Properties Test] After construction in the living room, bedroom, and bathroom of a newly built high-rise apartment, the air purification capacity was measured using the gas detection tube method (GASTEC product GSP-200 detection tube 91PL & 122P).

[0065] In addition, the changes in total volatile organic compounds (TVOC) and formaldehyde (HCHO) release were measured on days 1, 7, 14, and 21 for 3.5T of domestically produced MDF (medium-density fiberboard) and domestically produced HDF (high-density fiberboard) used in general construction.

[0066] Blue light removal efficiency The spectra of the insect-repellent and antibacterial lighting of the present invention and ordinary LED lighting at different wavelengths are listed in Table 1.

[0067] Table 1 [Insect Attraction Inhibition Test] An antibacterial composition was coated onto a 1m x 1m white cloth and dried to prepare a coated cloth. At night, the coated cloth was laid on the wall of an outdoor building, and the cloth was illuminated with light to count the number of insects attracted.
