Antibacterial lamp

Abstract

To provide an antibacterial lamp that can have both lighting and antibacterial effects. [Solution] The antibacterial lamp 100A includes a light-transmitting cover 1, a substrate placed inside the light-transmitting cover, a plurality of light-emitting diode chips 3 placed on the substrate, and a nano-coating placed on the light-transmitting cover. The light-transmitting cover has a housing space SP. The substrate is placed in the housing space. The light-emitting diode chips are placed in the housing space. The light-emitting diode chips are connected in series to form a high-voltage circuit HVC, and when power is supplied to the high-voltage circuit, a high-voltage electric field is generated around the light-transmitting cover. The nano-coating is placed on the light-transmitting cover. The nano-coating then dissociates antibacterial ions upon receiving radiation from the high-voltage electric field. As a result, the antibacterial lamp provides both a lighting effect and an antibacterial effect simultaneously.

Description

Technical Field

[0001] The present invention relates to an antibacterial lamp, and particularly to an antibacterial lamp capable of dissociating to form antibacterial ions in a high-voltage electric field.

Background Art

[0002] In the antibacterial treatment of conventional antibacterial lamps, the energy of ultraviolet rays is harmful to the human body, and people around have to stay away from the irradiation area of existing antibacterial lamps. Also, ultraviolet rays with low penetration power are easily absorbed by dust particles, significantly reducing the antibacterial effect. Therefore, existing antibacterial lamps are limited to use in an environment with less particles.

[0003] Therefore, the inventors of the present invention considered that the above drawbacks could be reduced, and through intensive research and application of scientific principles, finally proposed the present invention with a reasonable design that effectively reduces the above drawbacks.

Means for Solving the Problems

[0005] To solve the above technical problem, one of the technical solutions adopted by the present invention is to provide an antibacterial lamp. This antibacterial lamp includes a light-transmitting cover having an accommodation space, a substrate disposed in the accommodation space, a plurality of light-emitting diode chips (LED chips) disposed on the substrate and connected in series to form a high-voltage circuit that generates a high-voltage electric field surrounding the light-transmitting cover when energized, and a nano-coating disposed on the light-transmitting cover that dissociates antibacterial ions when irradiated by the high-voltage electric field.

[0006] More preferably, the antimicrobial lamp further includes a photocatalytic coating that can dissociate hydroxide ions (OH-) upon irradiation of the plurality of light-emitting diode chips.

[0007] Furthermore, it is desirable that the nanocoating and photocatalytic coating be applied to the light-transmitting cover or mixed into the light-transmitting cover.

[0008] Furthermore, it is desirable that the total number of the multiple light-emitting diode chips be 80 or more.

[0009] Furthermore, it is desirable that the voltage of the high-voltage circuit be 400 volts or higher.

[0011] Furthermore, it is desirable that the multiple light-emitting diode chips be arranged within the light-transmitting cover in a single U-shape. [Effects of the Invention]

[0012] In summary, the antibacterial lamp disclosed by the embodiment of the present invention is configured such that "a high-voltage circuit is formed by connecting a plurality of light-emitting diode chips in series," and "the high-voltage electric field generated by this high-voltage circuit irradiates a nanocoating, thereby dissociating antibacterial ions," and can have both a lighting effect and an antibacterial effect.

[0024] In this specification, terms such as “first,” “second,” and “third” may be used to describe various components or signals, but it should be understood that components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term “or” as used herein may, as necessary, include one or more combinations of the related items listed.

[0025] Referring to Figures 1-5, this embodiment presents an antibacterial lamp 100A. As shown in Figures 1 and 2, the antibacterial lamp 100A includes a light-transmitting cover 1, a substrate 2 disposed inside the light-transmitting cover 1, a plurality of light-emitting diode chips 3 (LED chips) disposed on the substrate 2, and a nano-coating 4 and a photocatalytic coating 5 (e.g., TiO2) disposed on the light-transmitting cover 1.

[0026] As shown in Figures 1 and 2, in this embodiment, the light-transmitting cover 1 has a tubular hollow structure made of a light-transmitting material (e.g., glass, transparent acrylic, etc.). The light-transmitting cover 1 also has a housing space SP. The shape of the light-transmitting cover 1 can actually be adjusted according to the designer's requirements. For example, in another embodiment shown in Figure 5, the light-transmitting cover 1 of the antibacterial lamp 100B has a general bulb shape. In yet another embodiment shown in Figure 6, the light-transmitting cover 1 of the antibacterial lamp 100C has a general flat shape (e.g., ceiling lamp).

[0027] As shown in Figures 2 and 3, the substrate 2 is placed within the housing space SP. In this embodiment, the substrate 2 has a long plate-like structure. Multiple light-emitting diode chips 3 are evenly arranged on the substrate 2 and connected in series to form a high-voltage circuit (HVC). This high-voltage circuit (HVC) can generate a high-voltage electric field (HE) around the light-transmitting cover 1 when power is supplied. Of course, Figures 2 and 3 show only one embodiment of the present invention, and the present invention is not limited thereto. For example, an application form of the present invention may be an antibacterial lamp 100D, as shown in Figure 7, in which the substrate 2 and multiple light-emitting diode chips 3 are arranged to mimic a filament light bulb.

[0028] In the context of the high-voltage circuit (HVC), "high voltage" refers to a voltage higher than the 100 volts of a typical lighting device, and a voltage at which the high-voltage circuit (HVC) can generate a high-voltage electric field with sufficient energy to irradiate the nano-coating 4. The voltage of the high-voltage circuit (HVC) is preferably 400 volts or higher, but the present invention is not limited to this.

[0029] Preferably, the total number of the multiple light-emitting diode chips 3 is 80 or more, according to the voltage specifications of currently available light-emitting diode chips. This allows the high-voltage circuit (HVC) formed by connecting the light-emitting diode chips 3 in series to have the aforementioned "high voltage". Furthermore, when the number of the multiple light-emitting diode chips 3 is 80 or more, the light pattern (or illuminated area) formed by the coordinated action of the light-emitting diode chips 3 is more uniform, and the multiple light-emitting diode chips 3 can have a better heat distribution effect under the same power.

[0030] As shown in Figures 2 and 4, in this embodiment, the nanocoating 4 and photocatalytic coating 5 are uniformly applied or mixed on the outside of the light-transmitting cover 1. The thickness of the nanocoating 4 and photocatalytic coating 5 is designed so as not to affect the passage of light rays generated by the multiple light-emitting diode chips 3, but the present invention is not limited thereto. For example, the nanocoating 4 and photocatalytic coating 5 may also be applied or mixed on the inside of the light-transmitting cover 1.

[0031] When the nanocoating 4 is irradiated with a high-voltage electric field (HE) or light rays generated by multiple light-emitting diode chips 3, the nanocoating 4 further dissociates antimicrobial ions. In practice, the nanocoating 4 may be made of nanosilver, nanocopper, or nanozinc. That is, the antimicrobial ions may be nanosilver ions, nanocopper ions, or nanozinc ions, but the present invention is not limited thereto. In this embodiment, the antimicrobial ions are represented as nanosilver ions.

[0032] When the photocatalytic coating 5 is irradiated by multiple light-emitting diode chips 3, it dissociates hydroxide ions (OH-). As a result, the dissociated antimicrobial ions and hydroxide ions diffuse around the light-transmitting cover 1, which can suppress the growth and reproduction of microorganisms.

[0033] It should be emphasized that when the number of multiple light-emitting diode chips 3 is 80 or more, the thermal energy generated by them is evenly transferred to the photocatalytic coating 5. The photocatalytic coating 5 becomes more active when heated by the multiple light-emitting diode chips, thereby promoting the efficiency of the photocatalytic coating 5 in generating hydroxide ions when irradiated with light.

[0034] Furthermore, it is noteworthy that in this embodiment, multiple light-emitting diode chips 3 use light that can be used as illumination (for example, white light), and a large number of light-emitting diode chips 3 are connected in series to generate a high-voltage electric field, which in turn generates antimicrobial ions and hydroxide ions. As a result, the antimicrobial lamp 100A of this invention can simultaneously provide good illumination and good antimicrobial effects without affecting human health.

[0035] In other words, "antibacterial lamps that connect a large number of light-emitting diode chips (LED chips) in series but do not generate a high-voltage electric field for generating antibacterial ions," or "antibacterial lamps that use light rays (e.g., ultraviolet rays) that affect human health," are not considered antibacterial lamps in this invention.

[0036] Of course, in other embodiments of the present invention not shown, the antimicrobial lamp may be configured such that, at the designer's request, only the nanocoating 4 is applied or mixed in to suppress the growth and proliferation of microorganisms by antimicrobial ions dissociated from the nanocoating (i.e., the photocatalytic coating 5 is omitted). This method also maintains the original technical effects of the present invention.

[0037] Furthermore, when multiple light-emitting diode chips 3 are connected in series and arranged in a straight line, the high-voltage electric field decreases in the order of connection. For example, assuming that the voltage corresponding to the first light-emitting diode chip 3 is 1200 volts, the voltage corresponding to the middle (i.e., the N / 2th) light-emitting diode chip 3 is 600 volts. The voltage corresponding to the last (i.e., the Nth) light-emitting diode chip 3 may be only 3 volts, which means that half of the light-emitting diode chips 3 arranged in a straight line may not have a voltage field sufficient to generate antimicrobial ions and hydroxide ions.

[0038] Table 1 below shows the data obtained from ATP bacterial testing. As is clear from Table 1, when multiple light-emitting diode chips 3 are connected to a voltage of 100 volts (V), the antibacterial effect (i.e., reduction in bacteria) achieved by the nanocoating 4 is approximately 21.9%. When multiple light-emitting diode chips 3 are connected to a voltage of 1200 volts (V), the antibacterial effect (i.e., reduction in bacteria) achieved by the nanocoating 4 is approximately 86.8%. In other words, multiple light-emitting diode chips 3 in the low-voltage section produce an antibacterial effect in cooperation with the nanocoating 4, but this effect is compared to the antibacterial effect achieved by the cooperation of multiple light-emitting diode chips 3 in the high-voltage section and the nanocoating 4.

[0039] [Table 1]

[0040] Therefore, as shown in Figures 8 and 9, the multiple light-emitting diode chips 3 of the antibacterial lamp 100E or antibacterial lamp 100F of the present invention are arranged in a U-shape within the light-transmitting cover 1 so that the nano-coating 4 and photocatalytic coating 5 on the light-transmitting cover 1 are reliably irradiated by the first to N / 2nd light-emitting diode chips 3 having a high-voltage electric field, either by forming two opposing U-shapes or a single U-shape. [Effects of the invention]

[0041] In summary, the antibacterial lamp disclosed in the embodiment of the present invention can simultaneously provide both a lighting effect and an antibacterial effect by "connecting multiple light-emitting diode chips in series to form a high-voltage circuit" and "irradiating a nanocoating with the high-voltage electric field generated by the high-voltage circuit to dissociate antibacterial ions."
