    [0001] [0001] This application claims the benefits of filing US provisional application No. 62 / 694,482, filed on July 6, 2018, and US provisional application No. 62 / 632,716, filed on February 20, 2018, which are incorporated herein by reference in their entirety. Field of Invention
    [0002] [0002] The present invention relates, in general, to a light emitting device and, more particularly, to a very short wavelength ultraviolet light emitting device. Background of the Invention
    [0003] [0003] Pathogens such as bacteria and viruses are everywhere, as on door handles, on telephones, on television remote controls, in public restrooms, on benches, on sidewalks, in the air, etc. Currently, there are many solutions for cleaning hand germs, such as hand sanitizer, baby wipes, etc. These products can help people who are on the move or who want a quick solution to clean their hands when washing with soap is not an option. However, pathogens are everywhere and it is often not feasible to place chemical wipes and / or cleaning solutions on all surfaces and / or in the air to be disinfected.
    [0004] [0004] In addition to chemical wipes and other cleaning solutions, short-wavelength ultraviolet light (UVC) is a proven and effective way to kill bacteria and other pathogens. Current UVC options for killing germs / bacteria, such as portable UVC sticks, fixed stepping mechanisms that help clean the sole of shoes, phone cases, etc., are often expensive and are not readily accessible to the average consumer and / or they usually have a specific specific use (for example, cleaning only the person's shoes or other element or device). In addition, there are risks with UVC light. For example, UVC light can cause skin cancer and / or cataracts. Therefore, there is a need for a human-safe, hand-held and / or portable and / disposable and / or rechargeable device that can be used to clean selected surfaces, localized areas and / or in the air around such surfaces to eliminate pathogens in a format that is readily available and accessible for everyday use by the average consumer. Summary of the Invention
    [0005] [0005] Far-UVC light, which is a narrow spectrum within UVC light, provides the same pathogen eliminating effect as UVC light, but without the detrimental effects of other frequencies or wavelengths. The present invention provides far-UVC in a hand and / or portable and / or disposable and / or refillable format that can be used every day, in common places for cleaning selected surfaces, localized areas and / or air in around a surface, being safe for humans, while eliminating pathogens. The device can be readily available and accessible for daily use by the average consumer.
    [0006] [0006] The handheld device includes a lighting part (invisible and / or visible light) and an activation part that provides illumination in the far-UVC spectrum to generate and emit far-UVC light in selected areas on the surface, located and / or in the air around a surface. The activation part provides selective activation of the lighting part for the duration necessary to generate and emit far-UVC light on the selected surfaces, the localized area and / or air around a surface. The device may include a handle to hold the device and direct the illumination in the far-UVC spectrum towards the selected surface and / or located area, thus generating and emitting far-UVC light on selected surfaces, located areas and / or in the air around a surface.
    [0007] [0007] In one aspect of the invention, a portable handheld device for disinfecting a surface or air around a surface includes a container or structure that includes an activation mechanism. At least part of the device or its container is transparent or translucent and, in response to activation of the activation mechanism, the handheld device emits ultraviolet light through the transparent or translucent part of the device or container for a limited period.
    [0008] [0008] Disclosure implementations may include one or more of the following optional features. In some implementations, the device or container includes a disposable single use device or container. The activation mechanism can include folding the device or container. Optionally, the activation mechanism includes shaking the device or container or exposing the device or container to air. In some implementations, the device or container includes a battery. The device or container can include a solar panel, and the solar panel can be operated to charge the battery when the solar panel is exposed to light (through which the solar panel, which comprises a plurality of photovoltaic cells that convert light energy in electric current, charges the battery). The battery, in some examples, includes a rechargeable battery. The portable handheld device or container may include a multipurpose device. In some implementations, the activation mechanism includes a button or switch.
    [0009] [0009] Another aspect of the disclosure provides a device for disinfecting a surface or air around a surface. The device includes a body, which includes a user input and a far-UVC light emitting source arranged on the body. The device also includes a power source to supply power to the far-UVC light emitting source. In response to user input, the far-UVC light source is powered and emits far-UVC light to disinfect the surface or air around the pathogen surface.
    [0010] [0010] This aspect may include one or more of the following optional features. The far-UVC light emitting source can emit far-UVC light with a wavelength between 200 nm and 230 nm. The far-UVC light emission source comprises a filter that filters light with a wavelength greater than 230 nm. In some instances, the device includes a visible light emitting source arranged on the body, and the visible light emitting source, when powered, emits visible light in the same direction as the far-UVC light emitting source emits far light. -UVC. The visible light emitted can be emitted by the device as visible reticles that illuminate an area that the far-UVC light, when fed, radiates. The visible crosshairs may be in focus when the device is at an ideal distance from the surface to be disinfected, and the visible crosshairs may not be in focus when the device is not at an ideal distance from the surface to be disinfected. In some implementations, the far-UVC light emitting source emits light at 360 degrees around the device.
    [0011] [0011] The device can include a cell phone. The device may include a light source that illuminates the pathogen, which emits light that illuminates the pathogen. The light source that illuminates the pathogen can emit light simultaneously with the far-UVC light source. The device may include a second user input and, in response to the second user input, the light source that illuminates the pathogen emits the light that illuminates the pathogen. The far-UVC light emitting source, in some implementations, emits far-UVC light with a wavelength of 222 nm. The device, in some examples, includes a stopwatch. The timer indicates that a period of time has elapsed after the user input has acted. The stopwatch can visually indicate that the time period has elapsed. The far-UVC light emitting source may automatically turn off after the time has elapsed. The time period can be selected by a user of the device through another user entry.
    [0012] [0012] The device optionally includes a refractor. The refractor can be adjustable to adjust the width of the light emitted. The device may include a base arranged on the body, where rotating the base causes the refractor to adjust the width of the emitted light. The device may include an indicator. The indicator indicates when the device is at an ideal distance from the surface to disinfect the surface. In some implementations, the indicator emits visible light when the device is at an ideal distance from the surface to disinfect the surface. The indicator can also emit an audible indication when the device is at an ideal distance from the surface to disinfect the surface.
    [0013] [0013] Another aspect of the disclosure provides a far-UVC handheld device to generate and emit far-UVC light on selected surfaces, localized areas and air around a surface. The device includes a lighting part. The lighting part provides illumination in the far-UVC spectrum to generate and emit far-UVC light to a surface or space around a surface. The device also includes an activation part. The activation part provides selective activation of the lighting part for a time sufficient to episodically generate and emit far-UVC light to disinfect the surface or space. The device also includes a handle. The handle provides a grip surface for a user to hold the device and direct the lighting part towards the surface or space to be disinfected and emit far-UVC lighting towards the surface or space to be disinfected.
    [0014] [0014] This aspect may include one or more of the following optional features. The surface or space can include at least one of an epidermis or a non-biological surface. The lighting part may include a lamp. The lamp generates and emits illumination with a wavelength equal to or less than 222 nm. The lighting part may include a lamp that generates and emits far-UVC lighting that has a wavelength greater than 222 nm. The device also includes a filter to filter the light emitted with a wavelength greater than 222 nm. The lighting part can include at least one selected from the group consisting of: (i) an excimer lamp and (ii) a light emitting diode. The lighting part may otherwise be any suitable light source or light source or lamp that is capable of emitting UVC and / or far-UVC lighting when energized, powered or activated.
    [0015] [0015] The lighting part can include a spotlight or with a focus medium or feature. The focus feature optically focuses on lighting on the surface or in the air (or point in space not on a surface or structure). The focus feature includes, in some examples, a lens and illuminated evidence. Illuminated signals provide feedback regarding a direction of illumination emitted far-UVC. The lighting part includes, in some embodiments, a reflecting surface, the reflecting surface reflects and intensifies the far-UVC lighting generated by the lighting part for the surface or the air or space.
    [0016] [0016] Another aspect of the disclosure provides a method of disinfecting a surface. The method includes providing a handheld device that includes a first light source that emits far-UVC light and a second light source that emits visible light. The method also includes the emission, by the first light source of the handheld device, of far-UVC light. The method also includes the emission, by the second source of the handheld device, of visible light. Visible light provides a visible indication of the target direction of the far-UVC light emitted. The method also includes directing the far-UVC light emitted towards the surface to be disinfected, directing the visible light emitted on the surface to be disinfected and indicating, by the hand device, when the hand device is at an ideal distance from a surface to be disinfected. In response to the indication that the device is at an ideal distance from the surface to be disinfected, the method includes disinfecting the surface by irradiating the surface with the far-UVC light emitted. Indicating when the handheld is at an ideal distance may include focusing on the visible light emitted on the surface when the handheld is at an ideal distance from the surface to be disinfected.
    [0017] [0017] Another aspect of the disclosure provides a portable device for disinfecting a surface or air around a surface, and the device includes a body that includes a user input. The device also includes a far-UVC light emitting source arranged in the body, and the far-UVC light emitting source emits far-UVC light between 220 nm and 225 nm. The device also includes a visible light emitting source arranged on the body, and the visible light emitting source emits visible light in the same direction as the far-UVC light emitting source emits far-UVC light. The visible light emitted is emitted by the device as visible reticles that illuminate an area that far-UVC light radiates. The visible crosshairs are in focus when the device is at an ideal distance from the surface to be disinfected and the visible crosshairs are not in focus when the device is not at an ideal distance from the surface to be disinfected (such as too close or too far from the surface ). The device also includes a power source to supply power to the far-UVC light emitting source and the visible light emitting source. In response to user input, the visible light emission source and the far-UVC light source are fed and the far-UVC light source emits far-UVC light to disinfect the surface or space where the visible reticles are focused.
    [0018] [0018] These and other objects, advantages, purposes and characteristics of the present invention will become evident after reviewing the following specification together with the drawings. Brief Description of the Drawing

    [0023] [0023] A hand-held and / or portable and / or disposable and / or rechargeable device for disinfecting a surface or air around the surface operates to emit far-UVC light in order to eliminate pathogens. The device includes a unit with an activation mechanism. When the activation mechanism is activated, the device emits ultraviolet light. The device can then be manipulated so that the desired surface and / or air and / or space to be disinfected is irradiated in far-UVC light, thus cleaning the surface and / or air of pathogens.
    [0024] [0024] With reference now to the drawing and the illustrative embodiment shown therein, a device 10 includes a unit 12. The unit 12 can have any suitable shape and at least part of the unit 12 is transparent or translucent. Unit 12 includes an activation mechanism 14. Although the illustrated embodiment shows the activation mechanism as a switch or alternator, it is understood that the activation mechanism can take any number of forms, which are described in more detail below. When the activation mechanism 14 is activated, the unit 12 emits far-UVC light through the transparent or translucent part. Optionally, the unit includes a power source 16.
    [0025] [0025] Pathogens, such as bacteria and viruses, are everywhere, such as on door handles, on telephones, on television remote controls, in public restrooms, on counters, on sidewalks, in the air, etc. Currently, there are easy and affordable solutions for cleaning your hands from germs, such as Purell hand sanitizer, baby wipes, etc. These products help people who are on the move or who want a quick solution to clean their hands if they are unable to wash their hands with soap. However, pathogens are everywhere and it is often not feasible to place chemical wipes and / or cleaning solutions on all surfaces and / or in the air to be disinfected.
    [0026] [0026] In addition to chemical wipes and other cleaning solutions, short-wavelength ultraviolet light (UVC) is a proven and effective way to kill bacteria and other pathogens. While there are currently some UVC options for killing germs / bacteria, such as portable UVC sticks, fixed stepping mechanisms that help clean the sole of shoes, phone cases, etc., these UVC light options are often expensive and they are not readily accessible to the average consumer and often have a specific specific use (for example, just cleaning the person's shoes or other element or device). In addition, there are risks with UVC light (for example, it can cause skin cancer and / or cataracts). Electromagnetic radiation (EM) includes all light or illumination that propagates radiant electromagnetic energy through space with the use of waves. EM radiation, for example, includes visible radiation (to the human eye) and invisible radiation, such as visible light, radio waves, microwaves, ultraviolet, gamma rays, etc. UVC light or illumination is short-wave germicidal ultraviolet EM radiation that is generally 100 nm to 280 nm in wavelength. However, far-UVC light or illumination, which is a narrow spectrum within UVC light (for example, 200 nm to 230 nm), can provide the same effect of killing germs / bacteria without the harmful side effects. As used herein, light and illumination can be used interchangeably to refer to visible or invisible EM radiation.
    [0027] [0027] According to the present invention, a device to reduce germs and increase health, placing the sterilizing power of far-UVC in an inexpensive, disposable and / or single use (or few uses) and portable format for the daily use is provided. The device consists of a small portable unit (which can take various forms) which, when activated, emits far-UVC light. The unit can be activated by any number of means, such as pressing a switch or flexing, pressing, tightening, shaking and / or exposing the unit to air to activate it. After activation, far-UVC light can be used to irradiate surfaces to kill pathogens and remain activated for a limited period (similar to, for example, a typical chemical glow stick or chemical hand warmer). The device can sterilize many types of surfaces (for example, epidermis or a non-biological surface, such as a table). The device can also radiate air to clean and kill pathogens above and / or around surfaces. The device can then be easily disposed of (for example, in a trash can) as soon as the far-UVC light ends. The present invention is more effective and has more applications than traditional chemical wipes or cleaning solutions, is not harmful like traditional UVC light, is easy to activate and allows portability.
    [0028] [0028] The device can use a variety of means to generate energy to power or energize a far-UVC light source (arranged in the body or unit). For example, the device can use disposable or rechargeable batteries, chemicals, solar energy, wind energy and / or any other type of mechanism to activate and / or generate far-UVC light. Optionally, the far-UVC light source can emit light responsive to a chemical reaction when the device or unit is flexed, compressed, agitated or the like. Alternatively, the device can be activated or deactivated using a switch, button, etc.
    [0029] [0029] In another aspect of the invention, the device can use a rechargeable battery to allow multiple uses of the device (where the device can be connected to recharge). In yet another aspect of the invention, the device can comprise any suitable form of mobile device, such as, for example, a cell phone or other mobile device that is operable to switch between regular visible light emission (such as a function flashlight), and ultraviolet light. The device, in some examples, may include a traditional flashlight shape. That is, the device can be a flashlight with a reusable UV light source (LED lamp, fluorescent lamp, excimer lamp, etc.) and a power source (replaceable batteries, rechargeable batteries, non-replaceable batteries, capacitors, etc.) .
    [0030] [0030] The device can emit far-UVC light in several ways. This includes the use of lamps of various technologies (incandescent, fluorescent, LED, excimmer lamp, etc.). When including a lamp, the lamp can take any appropriate shape. For example, the lamp and / or reflector can be shaped to focus the light emitted in a relatively narrow area.
    [0031] [0031] In some implementations, the device may include a stopwatch. The timer can start measuring the time when the user input to power the far-UVC light emitting light source is triggered. The timer can measure a period of time that is sufficient for the far-UVC light to eliminate most pathogens (for example, ten seconds). The stopwatch can include a visual, audible or tactile indication that the time period has elapsed (for example, an LED, an audio signal, vibration, etc.). Optionally, the timer can disable the light source at the end of the time period. The timer can be user configurable or allow selection from a set of predetermined time periods (for example, ten, thirty and sixty seconds). Thus, a user can activate the device by pressing a button, and then the device will operate for a predetermined period of time (without additional input or holding the button by the user) and then automatically turn off.
    [0032] [0032] The device may include a lamp that emits far-UVC light that is generally between 180 nm and 300 nm in wavelength. For example, the lamp can emit light between 200 nm and 235 nm in wavelength. UVC light in this spectrum is believed to kill pathogens. The device may include a filter (for example, chemical filtration, optical filter (s), etc.) to filter UVC light over a narrower spectrum of wavelengths (for example, from 200 nm to 235 nm) . When the light source emits a narrow spectrum of light (for example, 200 nm to 235 nm), the filter can act as a secondary safety measure to ensure that only the appropriate wavelengths are emitted by the device. The light source can also emit a wide range of frequencies and the filter can act as the main method of controlling the wavelength. In some instances, the device can filter UVC light with wavelengths greater than 230 nm. The filter, in some implementations, has a maximum frequency response between 220 nm and 225 nm (for example, 222 nm). UVC light with a wavelength of approximately 222 nm is still capable of destroying pathogens or providing antiseptic solutions without causing damage to the epidermis or the sight of people exposed to light. Therefore, it is desirable to prevent the light from exceeding about 222 nm. Chemical filtration can be included in a bulb of the device or in a filter located elsewhere within the device. An optical filter can be placed so that the light emitted by the device passes through the optical filter. An optical filter can be included in the device's own lamp or as a separate element (for example, like a film on a lens or lamp on the device or between the lens and the lamp). In some instances, lamp 28 can generate only far-UVC light that is at or below about 222 nm, so filtration is not necessary.
    [0033] [0033] According to another aspect of the invention, the device emits light that makes bacteria and other pathogens visible to a user of the device to allow the user to determine the cleanliness of an area. For example, the device can emit fluorescent light that illuminates bacteria. The device can emit the light that illuminates the pathogen simultaneously with the far-UVC light or separately from the far-UVC light. That is, pathogens can be illuminated (ie made visible to the user) when far-UVC light is in use to direct cleaning locations or, alternatively, before and after far-UVC light is used to assist in cleaning and assess effectiveness. The light that illuminates the pathogen can be emitted from the same light source (for example, lamp) as far-UVC light or from a separate light source (that is, a light source that illuminates the pathogen, which emits the light that illuminates the pathogen). The device may include additional user input (for example, button or switch) to activate the light that illuminates the pathogen separately from the far-UVC light.
    [0034] [0034] Referring now to Figures 2A and 2B, a far-UVC 20 light-emitting device includes a base 22 and an upper part 24. The base 22 and the upper part 24, although exemplified as a "lipstick case" box ", can take any suitable shape (for example, rectangular, tubular, triangular, flexible / foldable / adaptable, etc.). The top 24 connects to the base 22 to enclose the device 20 (figure 2A). When the upper part 24 is removed (for example, pulling, twisting, releasing a lock, etc.), the light source or lamp compartment 26 is exposed. Lighting, as defined in this document, refers to the act of lighting an object or the air with visible or invisible light (for a user). The lamp compartment may include a lamp 28 or other light source that emits far-UVC light. Lamp 26 can be any lamp that is capable of producing wavelengths in the far-UVC spectrum (for example, excimer or excilamp, LED, etc.). The lamp compartment 26 can also house a filter 30 that filters the wavelength of the light emitted by the lamp 28. The filter 30 can be activated whenever the light source 28 is activated (for example, by pushing, pressing, pulling, flex, shake, etc. device 20). The device can also be activated using biometrics (for example, fingerprint sensor or facial identification).
    [0035] [0035] The device can also include a lens 32. Lens 32 can focus the light emitted in a narrower or wider beam. The lamp compartment 26 may further include the support 34 and the reflective panel 36 to further direct and control the emitted light. In some implementations, device 20 includes an activation and / or deactivation user input 38 (for example, a switch, slider, alternator, button, etc.). User input 38, when triggered or activated, can power or deactivate lamp 26, thereby causing device 20 to emit far-UVC light or to stop emitting far-UVC light. User input can episodically power lamp 26 for a period of time sufficient to generate and emit far-UVC light to disinfect the target surface or space. The device 20 may further include an energy level 40 which indicates the amount of energy remaining in a power supply. The power supply can be a replaceable battery, a rechargeable battery, an electrical plug-in source, a solar source, etc.
    [0036] [0036] With reference now to figures 3 and 4, device 20 emits far-UVC light to radiate an object or target area to be cleaned. For example, as shown in figure 3, a user can hold the device 20 in one hand, while radiating the other hand to clean the pathogens hand. Device 20 may include a handle 21 for holding the device by the user of the device (for example, holding the device in the user's hand). For example, device 20 may include a rubberized surface for the user to hold on, while directing lighting towards the surface or air to be disinfected.
    [0037] [0037] Device 20 can have an ideal operating distance. That is, device 20 can operate more efficiently when disposed at a predetermined distance from the object or area. For example, device 20 may preferably operate six to eighteen inches from the object or area. The ideal distance can be about 30 centimeters. Device 20 can emit a visible indication to indicate when the device is at optical distance from the object or area. For example, when the device emits visible lattices, as discussed earlier, the lattices can be diffuse and out of focus when the device 20 is closer or further than the ideal distance, and the lattices can be in focus when the device 20 is at the ideal distance. Device 20 can indicate the appropriate distance in other ways (for example, an LED on device 20 or an audible tone). Device 20 can measure distance using another sensor (for example, an infrared distance sensor).
    [0038] [0038] As shown in figure 4, device 20 can emit far-UVC light in a narrow wavelength band (for example, at or near 222 nm). The reflective panel 36 disposed behind the lamp 28 can increase the density of the light in front of the lamp 28, thereby increasing the effective distance between the device 20 and the desired target area. The device 20 may include a refractor to focus the light, for example, opening or closing an aperture or moving or manipulating the lens or the reflective panel. The light can be focused, for example, by twisting the base 22 of the device 20, in much the same way as twisting an adjustable brass hose nozzle. The light can be focused in any other suitable way (for example, by pressing a button, sliding a slider, pushing or pulling the base, turning a button, lens or lamp, etc.). Such an adjustment allows the device 20 to radiate a wider or narrower range of area as desired by the user.
    [0039] [0039] In accordance with the present invention, the device provides a means for disinfecting small surface areas and / or the air around the surface areas. For example, shoes before entering the house, bathroom taps, door handles, public table before eating, utensils, toys, remote control, sinks, office spaces, etc. When activated, the device works to eliminate harmful bacteria and germs that cause diseases that are not visible to the human eye.
    [0040] [0040] Changes and modifications to the modalities specifically described can be made without departing from the principles of the invention, which is intended to be limited only by the scope of the appended claims, as interpreted in accordance with the principles of company law. patents, including the doctrine of equivalents.
