Abstract
Description
Technical Field
[0001] The present invention relates to an antibacterial composition and insect-proof antibacterial lighting including the same.
Background Art
[0002] Generally, lighting fixtures include various lighting fixtures such as LED lighting, fluorescent lamps, incandescent lamps, or halogen lamps, and are essentially installed in offices, homes, reading rooms, schools, hospitals, or industrial facilities, etc., and are used as a limited function of illuminating dark places such as a function of illuminating the interior brightly. Among these lighting fixtures, LED lighting fixtures are dominant from the viewpoints of luminous efficiency and energy saving in order to use power efficiently.
[0003] In addition, in an indoor environment such as an office, a reading room, an examination hall (one-room type staying facility), or a house where various lighting fixtures including LED lighting fixtures are installed, if ventilation is not sufficiently performed, the indoor humidity rises, and as a result, a humid environment is maintained, and problems such as bad odors and bacteria breeding and threatening the health of residents occur. Also, in modern society, not only bacteria but also diseases such as so-called "sick house syndrome" are spreading due to volatile organic compounds such as formaldehyde, xylene, toluene, benzene, or acetone.
[0004] Furthermore, in the case of outdoor lighting, there is a problem that many insects are attracted in summer, and although insect-proof lighting is used to prevent this, there is also a problem that this has limitations.
[0005] Therefore, research on lighting fixtures having a deodorizing function and an insect-proof effect simultaneously is required.

[0046] The aforementioned lighting device is not limited to any device that can illuminate a certain area, such as direct lighting that directly emits light including a light source, or indirect lighting that indirectly emits light via reflected light from an external light source, and can refer to conventional lighting modules, lighting fixtures, and lighting, etc. Specific examples include LED lighting, fluorescent lamps, incandescent lamps, ceiling lights, downlights, spotlights, searchlights, horizon lights, multi-light pendants, floor lamps, chandeliers, pool lights, wall-mounted lights, kitchen lights, living room lights, flat edge lights, square ceiling lights, round ceiling lights, cross lights, line lights, square button sensor lights, round sensor lights, round surface-mounted lights, elliptical surface-mounted lights, underground lighting, parking lot lighting, FPL fluorescent lamps (Fluorescent Parallel Lamps), PL luminaires (Parallel Lighting fixtures can be used to illuminate such as insect-repellent and antibacterial lighting, selected from any of the following: lamps, short ball bulbs, long ball bulbs, one-room button type lights, square button type lights, cross lights, long stand lights, mood lights, factory lights, desk stand lights, slim surface lighting, bathroom lights, sink lights, shoe rack lights, flat edge futures, flat bezel edges, square floodlights, signal lights, sensor lights, surface-mounted lights, recessed floodlights, signboard lights, flat lights, surface lighting, marine floodlights, landscape lighting, factory floodlights, tunnel lights, waterproof surface flat lights, emergency lighting downlights, LED lighting for gas stations, guide lights, emergency lighting, lighting for high temperature and high humidity environments, emergency lighting flat lights, sports lighting, floodlights, and landscape lighting, parking lot lights, moisture-proof lights, parking lamp lights, security street lights, pedestrian crossing floodlights, street lights, garden lights, security lights, tree lights, and automobile headlights. Specifically, LED lighting fixtures can be used, but are not limited to these.
[0047] According to one aspect of the present invention, the LED lighting fixture may be a bulb type, a bar type, a street light type, or a floodlight type.
[0048] According to one aspect of the present invention, an insect-repellent and antibacterial lighting fixture can be provided in which the insect-repellent and antibacterial composition is coated onto an LED light fixture. By applying the insect-repellent and antibacterial composition to the LED light fixture, not only are antibacterial and deodorizing effects achieved, but the phenomenon of insects and other pests being attracted to light can also be suppressed.
[0049] According to one aspect of the present invention, the LED lighting may have a color temperature range of 2,000K to 6,000K, and more specifically, 2,000K to 3,000K. If the color temperature range of the LED lighting is 3,000K or less, it can emit yellow light, and if it is 3,000K or more, it can emit white light.
[0050] If the aforementioned color temperature range is 2,000K to 3,000K, the number of insects attracted to the light emitted from the LED can be further suppressed.
[0051] According to one aspect of the present invention, by using LED lighting that satisfies the aforementioned color temperature range and has a wavelength band of 510 to 700 nm, the number of insects attracted to the light can be significantly suppressed.
[0052] Figure 4 is a table showing the wavelength range of insect-repellent and antibacterial lighting, the wavelength range of commercially available LED lighting, and the blue light cut rate.
[0053] Conventional LED lighting uses wavelengths in the 300-700nm range, but in this invention, in order to effectively suppress insect attraction, wavelengths in the 300-500nm range may be blocked, and specifically, LED lighting with a wavelength range of 510-700nm may be used.
[0054] By using LED lighting having a wavelength range of 510 to 700 nm, the insect repellent effect is excellent, and in particular, when the insect-repellent and antibacterial composition is applied to the LED lighting with a wavelength range of 510 to 700 nm, the antibacterial, deodorizing, and insect repellent effects can be further enhanced.
[0055] The LED manufacturing process is carried out in the following order: epi wafer manufacturing, chip production, packaging, and module production. The epi wafer may be, but is not limited to, a SiC substrate.
[0056] Furthermore, as another aspect of the LED manufacturing process, a packaging process may be introduced, which may include, but is not limited to, a step of connecting the manufactured chip and lead and packaging them so that the maximum amount of light is emitted to the outside, and a module process step of mounting the LEDs onto a certain frame using the packaged LEDs.
[0057] Furthermore, in the present invention, as a method for realizing a blue light or blue light blocking LED in the 300-500 nm wavelength band, an LED can be used as an excitation light source, and a fluorescent material that emits yellow (510-700 nm) YAG (Yttrium Aluminum Garnet) may be used as the excitation light source. However, this is merely one example, and the invention is not limited to this, as long as it can remove the 300-500 nm wavelength band.
[0058] In particular, according to one aspect of the present invention, by applying the antibacterial composition to an LED lamp, not only an insect-repellent effect but also a photocatalytic effect can be achieved.
[0059] The aforementioned photocatalytic effect refers to the effect of reducing air pollutants such as NOx and SOx to water and carbon dioxide, but the general photocatalytic effect is not limited to this.
[0060] The present invention will be described in more detail below based on examples and comparative examples. However, the following examples and comparative examples are merely examples to illustrate the present invention in more detail, and the present invention is not limited to the following examples and comparative examples.
