Description

FAR UVC LIGHT DEVICE
INTRODUCTlON
Our product is a fixed or portable, single self-contained plug and play light bulb / source, that contains white light and UVC or white Bght and FAR UVC whilst the white light can be incorporated into variable light sources as mentioned herein below. it follows that our product could either be;
(a) FAR UVC (UV frequency below 222 nm) with white fight and incorporated and compatibte/mterchangeable with any normal light bulb (shape or size or base or in any country) , including but not limited to screw in and or bayonet fitting and or any other fitting, including but not limited to incandescent bulbs, strip light , fluorescent , compact fluorescent, halogen , LED (light emitting diode) or any torch light bulb or;
(b) UVC (UV frequency above 222nm but below 253nm) with white light and incorporated with and compatible / interchangeable with any normal light bulb (shape, size or base or in any country ) including but not limited , screw m and or bayonet fitting or any other fittings and including but not limited to incandescent bulbs, fluorescent , strip light , compact fluorescent, halogen , LED (light emitting diode) with Incorporated inter alia timer and/or motion detected safety features. This built in safety device is to avoid any risks such as radiation or red eyes to humans associated with UVC. It's for this reason our UVC will only operate for a maximum period of 30 min (this wilt be less should the railing be lower or the UVC is in a portable unit dose to bacteria) and only operatabfe when there are no human activities.
Our product wMI indude an adjustable / interchangeable filter to change frequency of UVC for different applications
The above will be available in a wide spectrum of voltages to replace any current bulb (shape, size or base or in any country) , used in the widest sense induding house hold, commercial, medical, automotive (eg cars and taxis), as well as used in aviation, as described herein, any ranges between 12v to 380v, with the required safety features when normal UVC is used.
Simply put, this is a single light source comprising of UVC of which the source of UVC is from an LED (with safety features as described above) or FAR UVC source from LED OR adjusted F t!lered UVC, in one single unit, any of which shall be combined with white light embodied into a single unit , and replacing any existing light source in the widest sense / fitting , fixed or portable, used Indoors or outdoors which incorporates (UVC with safety feature or FAR UVC, with the intend and purpose to kill bacteria or other microorganisms, including mould spores, yeast and virus, with UVC and FAR UVC only.
BACKGROUND TO THE INVENTION
It has been found that bacteria or other microorganisms, including mould spores, yeast and virus, can be destroyed on exposed surfaces If they are subjected to ultraviolet light (UV) However, a UVC of a frequency of 253nm has been found to be harmful to humans. To the contrary research now confirms that UCV (FAR UVC) with a frequency of smaller than 222nm has been found not be harmful to humans. The exposure to UV light necessary to kill bacteria (or the "kill" factor) is a product of time and intensity. If the bacteria or mould spores are hidden below the surface of a material or are not in the direct path of the rays, they will not be destroyed. It is for this reason that we have designed a FAR UVC that can be incorporated into a mobile unit such as a torch to serve this purpose and kill such hidden bacterial spores underneath surfaces or UVC with safety features that can kill such bacteria when replaced with an existing light bulb or source. Because of the absolute necessity for antiseptic surroundings, tubes that emit light of the required wavelength are often used in operating rooms, wards and nurseries of hospitals, and, as used today, are fixed to walls or ceilings.
Our product is either fixed or portable, single self-contained plug and play light bulb, that contains white light and UVC or white light and FAR UVC whilst the white light can be incorporated Into variable light sources as mentioned herein below to serve as normal light source or during certain times be activated to use UVC or FAR UVC to kill inter alia harmful bacteria.
It follows that our product could either be;
(a) FAR UVC (UV frequency below 222 nm) with white light and incorporated and compatible/interchangeable with any normal light bulb (shape or size or base or in any country) , including but not limited to screw in and or bayonet fitting and or any other fitting, including but not limited to incandescent bulbs, strip light , fluorescent , compact fluorescent halogen , LED (light emitting diode) or any torch light bulb or;
(b) UVC (UV frequency above 222nm but below 253nm) with white light and incorporated with and compatible / interchangeable with any normal light bulb (shape, size or base or in any country ) including but not limited , screw in and or bayonet fitting or any other fittings and including but not limited to incandescent bulbs, fluorescent , strip tight , compact fluorescent, halogen . LED (light emitting diode) with incorporated inter atia timer and/or motion delected safety features. This built in safety device is to avoid any risks such as radiation or red eyes to humans associated with UVC. It's for this reason our UVC will only operate for a maximum period of 30 min (this will be less should the ceiling be lower or the UVC is in a portable unit dose to bacteria) and only operatabte when there are no human activities. Our product will include an adjustable / interchangeable filter to change frequency of UVC for different applications
The above will be available in a wide spectrum of voltages to replace any current bulb (shape, size or base or in any country) , used in the widest sense including house hold, commercial medical, automotive (eg cars and taxis), as well as used in aviation, as described herein, any ranges between 12v to 380v. with the required safety features when normal UVC is used.
Simply put. this is a single light source composing of UVC of which the source of UVC is from an LED (with safety features as described above) or FAR UVC source from LED OR adjusted Filtered UVC, in one single unit, any of which shall be combined with white light embodied into a single unit . and replacing any existing light source in the widest sense / fitting . fixed or portable, used indoors or outdoors which incorporates UVC with safety feature or FAR UVC, with the intend and purpose to kill bacteria or other microorganisms, including mould spores, yeast and virus, with UVC and FAR UVC only.
OBJECT ON INVENTION
The instant invention is tile first of its kind to enable ali households, businesses both private and commercial, any person who owns a vehicle, aeroplane, helicopter. In other words this product can be used in the automotive and aviation sector, as well as hospitals, medical clinics, food processing centers, normal households, to name a few, concerned with cleaning bacteria and other microorganisms.
Our product is a fixed or portable, single self-contained plug and play light bulb, that contains white light and UVC or white light and FAR UVC whilst the white light can be incorporated into variable light soirees and serve its original purpose as mentioned herein.
Our product will be available in wide spectrum of voltages to replaces any current bulb, shape, size or base in any country. Simply put, this is a single life source which comprise of either UVC with white light, with built in safety features as described herein above or FAR UVC with white light in one single unit replacing any existing light source as described herein above.
