Description

TITLE: “Lighting apparatus for sanitation of environments”
DESCRIPTION FIELD OF THE INVENTION
The present invention relates to a lighting apparatus for sanitizing environments. BACKGROUND
A known apparatus for surface sterilization is known under the trade name IDROSTERIL This apparatus mounts an 18 W low pressure neon lamp where the glass of the neon completely retains all ultraviolet (UV) radiation including UV-C radiation.
This apparatus was born as a cure for psoriasis.
The processes always take place on the same band but with different wavelengths where some pathogens cannot be reached. Their wavelength stops at 220 nm and is more targeted to influenza viruses, in fact they were used in elementary and nursery schools to reduce the flu load The scope of the present invention is therefore the sanitation of environments, also dedicated to food shops and sanitary facilities, and in particular of the surfaces where bacteria and viruses are deposited and contaminate such environments, increasing the sanitizing effectiveness with respect to the known art.
A further scope is to provide a lighting apparatus for sanitizing environments that can be cataloged as a medical surgical apparatus and as a medical apparatus.
A further scope of the invention is to achieve the above in a simple and economical way. Other scopes and advantages of the invention will become apparent from the following description.
BRIEF SUMMARY OF THE INVENTION
These scopes are achieved by a lighting apparatus for sanitizing environments, where said apparatus comprises a mobile parallelepiped body, where a power supply is mounted on said mobile parallelepiped body to power at least one lamp, where said lamp is a configured lamp to emit radiations in the UV-C band, said radiations being suitable for completely sanitizing the environments in which the lighting apparatus is placed. In particular, the lighting apparatus includes a timer and a control unit configured to carry out a timed sanitation cycle having an adjustable duration.
The invention has numerous and important advantages.
Firstly, the lamps are configured to emit UV-C radiation that can have the maximum sanitizing effect against viruses and bacteria. Secondly, it is possible to correlate the square footage to be sanitized with the time of exposure to UV-C radiation, that is, by increasing the exposure time, the square footage to be sanitized can be increased.
According to an embodiment of the present invention, a proximity sensor configured to operate at 360° is provided in the lighting apparatus in order to cause an immediate blocking of the operation of the lighting apparatus in case of need for the safety and protection of any objects/people.
This feature allows the luminaire to operate in maximum safety.
Not least advantage of the invention is given by the fact that the lighting apparatus is easily transportable, wheels being provided to allow the mobility of the lighting apparatus itself.
Further characteristics of the invention can be deduced from the dependent claims.
BRIEF DESCRIPTION OF THE DRAWINGS
The advantages of the invention are evident from an examination of the figures illustrated in the attached tables, where:
- Figure 1 illustrates a first perspective view of the lighting apparatus for sanitizing environments, according to an embodiment of the present invention; and
- Figure 2 illustrates a second perspective view of the lighting apparatus for sanitizing rooms of Figure 1. DETAILED DESCRIPTION OF THE INVENTION
With reference to Figure 1 , there is a first perspective view of the lighting apparatus for sanitizing environments, according to an embodiment of the present invention, and globally indicated with the reference numeral 10. The lighting apparatus 10 is substantially composed of a parallelepiped body which can be moved by means of wheels (not shown for simplicity), or even by using a trolley (also not shown for simplicity).
The dimensions of the parallelepiped body are 78 cm in height, 68 cm in width and 45 cm in depth. It is quite clear that such dimensions have been mentioned purely by way of non limiting example of the present invention.
The lighting apparatus 10 provides a plurality of lamps 20; in particular a lamp 20 for each side of the parallelepiped body where each of said lamps 20 can be a 250 Watt UV-C lamp, equipped with a protection grid. This advantageously allows to sanitize simultaneously in every direction and therefore being particularly suitable for sanitizing all-round rooms in an efficient and rapid way.
The lifespan of the lamps can be 2,000 hours.
Lamps 20 can be gas discharge arc lamps (Xenon lamps), designed to completely sanitize environments from COVID-19, viruses and bacteria. The lighting apparatus 10 further provides one or more fans 30 for the recirculation of air, both of which are equipped with a grill.
The lighting apparatus 10 also provides a proximity sensor 40 whose function will be better illustrated below.
The lighting apparatus 10 also provides a control display, indicated with the numerical reference 50, to perform control functions of the luminaire itself, for example its timed switching on (also visible in Figure 2).
The lighting apparatus 10 also provides a timer 70 and a control unit 80 configured to carry out a timed sanitation cycle, as better illustrated below. Finally, the lighting apparatus 10 also comprises a 220 V power supply (not shown for simplicity), and an emergency button 60.
In the operation of the lighting apparatus 10, after pressing the start button, the disinfection cycle can start which starts automatically, for example after one minute.
At the beginning of the cycle, the 250 W UV-C lamps are switched on simultaneously, a buzzer is activated, just as the ventilation fan(s) 30 are also activated.
The duration of the disinfection cycle is adjustable from 1 to 10 minutes, and at the end of the cycle the machine switches off automatically.
The motion sensor 40 operates at 360° and can cause an immediate blocking of the operation of the lighting apparatus 10 within an arc of 8 m. This is to protect people who could come into contact with the appliance, as these radiations are known to be harmful to skin / eyes etc. As also mentioned previously, the lighting apparatus 10 for sanitizing environments performs its function in the following way.
Firstly, unlike apparatuss that use high frequencies, the luminaire 10 advantageously does not produce ozone (O3), since this substance if concentrated in closed environments is not recommended. More specifically, the luminaire 10 is equipped with 250 W high pressure Xenon lamps, whose electromagnetic spectrum shows that the ultraviolet falls in the wavelength between 100 and 400 nanometers and more specifically:
UV-A (320NM-400) - UV-B (280-320nm) and UV-C (100-280nm).
Scientific literature shows that the UV-C band can be defined as germicidal par excellence.
This band is able to reach, in addition to said microbes, more aggressive pathogens such as those of the coronavirus family.
In this case, only 5 minutes are sufficient, without the presence of people, to sterilize even the slightest surface. Purines and pyrimidines (thymine) are the main targets of the action of UV-C rays. Thymine absorbs UV-C and changes to such an extent that cells are no longer able to multiply and survive, in fact after exposure the organism dies without offspring and the population of the microorganism rapidly decreases. The inactivation of viruses is demonstrated under controlled laboratory conditions and its effectiveness depends on the following factors: wavelength, power, exposure time, surface area in square centimeters.
Based on the data in the possession of the scientific community, UV-C ultraviolet band germicidal technology plays a decisive role in reducing human-to-human transmission of viruses.
The electromagnetic radiations of the light emitted in this band, for at least 10 seconds, are able to inactivate the COVID-19 virus and two other close relatives coronaviruses or the Sars CoV and the MERS-CoV, and last but not least all the bacteria present on any surface. Inactivation has been demonstrated under controlled laboratory conditions. The process by which UV-Cs work is physical and not chemical. All viruses and bacteria tested to date have been destroyed by the radiation of ultraviolet type C, they act on the structure of DNA and RNA by breaking the bonds.
In conclusion, some examples of known art are reported such as US 2020/085983 where a spot sanitizing lamp is described, i.e. comprising a single unidirectional lamp which therefore allows to sanitize in only one direction at the same time, therefore being suitable for sanitizing objects and / or particular restricted areas, it is not suitable for sanitizing a room as with a single lamp the sanitization of a room would require exaggerated times, requiring continuous rotation. Still, a further example of the known art EP 2174670 describes a sanitizing apparatus comprising a battery of mercury lamps which is known to be a very toxic substance, for which this invention is not practicable as it is very dangerous to handle since the mercury is contained in a fragile part of the object. In particular, the present apparatus is innovatively characterized by the fact that said apparatus comprises a plurality of lamps 20, in particular a lamp 20 for each side of the parallelepiped body where each of said lamps 20 can be a UV-C lamp and in particular the lamps 20 are high-pressure Xenon lamps, this being therefore innovative and solving said problems of the known art.
Naturally, amendments or improvements may be made to the invention as described, dictated by contingent or particular reasons, without thereby departing from the scope of the invention.
