Description
Korte aanduiding: Werkwijze voor het creëren van een steriele ruimteShort indication: Method for creating a sterile space
BeschrijvingDescription
De uitvinding heeft betrekking op een werkwijze voor het creëren van een steriele omgeving in een ruimte.The invention relates to a method for creating a sterile environment in a space.
Het is van algemene bekendheid om een steriele omgeving in een ruimte te creëren door de wanden van die ruimte te voorzien van een antibacteriële, nano-oxidedeeltjes bevattende coating, bijvoorbeeld een Ti02-coating, hierna aangeduid met oxidecoating (zie bijvoorbeeld www.nanoservi-ces.nl/include/Antibacteriele_nano_RIVM_-_KIRnano.pdf).It is generally known to create a sterile environment in a space by providing the walls of that space with an anti-bacterial nano-oxide particle-containing coating, for example a TiO2 coating, hereinafter referred to as oxide coating (see, for example, www.nanoservices). .nl / include / Antibacteriele_nano_RIVM _-_ KIRnano.pdf).
Een dergelijke coating maakt het oppervlak zelfreinigend en zelfontsmettend, door het creëren van een hoog elektropo-tentiaal op de wand, wat de vorming van radicalen stimuleert. De ruimte wordt hiermee zelfsteriliserend. De coating wordt onder invloed van daglicht geactiveerd. Door de lichtenergie (fotonen) valt de oxidecoating uiteen in negatieve ionen en positieve ionen. Deze positieve ionen zijn altijd 0+-ionen (vrije zuurstofradicalen). Die vrije zuurstof radicalen breken door "oxygenatie" organische verbindingen af die zich als ongewenste verontreinigingen in de betreffende ruimte bevinden. Vervolgens komen het 0+-ionen weer vrij en binden zich dan in veel gevallen weer met het oorspronkelijk negatieve ion.Such a coating makes the surface self-cleaning and self-disinfecting, by creating a high electrical potential on the wall, which stimulates the formation of radicals. This makes the space self-sterilizing. The coating is activated under the influence of daylight. Due to the light energy (photons), the oxide coating breaks down into negative ions and positive ions. These positive ions are always 0 + ions (free oxygen radicals). These free oxygen radicals break down organic compounds through "oxygenation" that are present in the space concerned as undesirable impurities. Then the 0 + ions are released again and in many cases bind with the original negative ion again.
Voorwaarde voor een effectieve werking van de coating is wel dat de ruimte voldoende licht ontvangt met de juiste golflengte. Elke coating heeft gelijktijdig meerdere specifieke golflengtes nodig, om de coating-moleculen op te splitsen in ionen. Dit laatste is echter een probleem in veel ruimtes, met name in ziekenhuizen en kantoren, etc. die veelal zijn voorzien van daglicht-filterende beglazing en/of zonneweringen etc., om de warmte en lichtinval te beperken. Hierdoor is er onvoldoende aanbod in J/m2 van de benodigde golflengtes om het proces te activeren.A condition for effective coating operation is that the room receives sufficient light with the correct wavelength. Each coating requires several specific wavelengths at the same time, in order to split the coating molecules into ions. The latter, however, is a problem in many spaces, in particular in hospitals and offices, etc. which are often equipped with daylight-filtering glazing and / or sun blinds, etc., to limit heat and light. As a result, there is insufficient supply in J / m2 of the required wavelengths to activate the process.
De onderhavige uitvinding beoogt een oplossing voor dit probleem te bieden.It is an object of the present invention to provide a solution to this problem.
Ter ondervanging van het genoemde probleem voorziet de uitvinding in een werkwijze voor het creëren van een steriele omgeving in een ruimte met geen of beperkte toetreding van natuurlijk daglicht, omvattende de stappen van: - het aanbrengen van een oxidecoating op de wanden van de betreffende ruimte; - het aanbrengen van een of meer verlichtingsarmaturen die zijn ingericht voor het in de ruimte afgeven van kunstmatig opgewekt full spectrum daglicht, waardoor de benodigde golflengtes in voldoende mate worden aangeboden.To overcome the above-mentioned problem, the invention provides a method for creating a sterile environment in a space with no or limited natural daylight access, comprising the steps of: - applying an oxide coating to the walls of the space in question; - installing one or more lighting fixtures that are arranged for emitting artificially generated full spectrum daylight into the room, so that the required wavelengths are offered to a sufficient extent.
Daar waar door het aanbrengen van een oxidecoating niet het beoogde steriliserende/zelfreinigende en/of -ontsmettende effect kan worden bereikt als gevolg van het ontbreken van een voldoende hoeveelheid daglicht, wordt dit tekort volgens de uitvinding ondervangen door het aanbrengen van een of meer verlichtingsarmaturen die zijn ingericht voor het in de ruimte afgeven van kunstmatig opgewekt full spectrum daglicht, door middel van verlichtingsarmaturen die zijn voorzien van volspectrum-daglichtlampen, bij voorkeur vol-spectrum-daglicht-LEDs, vaak aangeduid als "full spectrum daylight" (fsd) LEDs, daar die laatstgenoemde uiterst energiezuinig zijn.Where the provision of an oxide coating cannot achieve the intended sterilizing / self-cleaning and / or disinfecting effect due to the lack of a sufficient amount of daylight, this deficiency according to the invention is overcome by installing one or more lighting fixtures that are adapted to emit artificially generated full spectrum daylight into the room by means of lighting fixtures provided with full-spectrum daylight lamps, preferably full-spectrum daylight LEDs, often referred to as "full spectrum daylight" (fsd) LEDs, the latter being extremely energy efficient.
Vol spectrum daglicht is nodig om de volgende redenen: het verbetert het lichtbeeld en contrastweergave, zodat de ruimte gewoon gebruikt kan worden, voor de functie waarvoor deze is ingericht en gelijktijdig worden de golflengtes met voldoende energie aangeboden om de coating te activeren. Wanneer enkel gekozen wordt om de voor oxygenatie benodigde golflengtes aan te bieden, dan is de ruimte niet meer te gebruiken voor zijn normale gebruiksfunctie of er moeten extra verlichtingspunten worden geïnstalleerd om dit te herstellen. Bijvoorbeeld maken de volspectrum-daglicht-leds deel uit van pseudo- of led tl-buizen, die zijn ingericht en uitgevoerd als vervangers van conventionele tl-buizen die daardoor simpelweg (of na enige aanpassing) in conventionele tl-armaturen kunnen worden geïnstalleerd.Full spectrum daylight is needed for the following reasons: it improves the light image and contrast rendering, so that the space can be used as normal, for the function for which it is designed and at the same time the wavelengths are provided with sufficient energy to activate the coating. If it is only chosen to offer the wavelengths required for oxygenation, the room can no longer be used for its normal use function or additional lighting points must be installed to restore this. For example, the full spectrum daylight LEDs are part of pseudo or LED fluorescent tubes, which are arranged and designed as replacements for conventional fluorescent tubes that can therefore simply (or after some adjustment) be installed in conventional fluorescent luminaires.
Het door de verlichtingsarmaturen geproduceerde licht heeft bij voorkeur een kleurtemperatuur van ten minste 5500K, bij meer voorkeur ten minste 6000K en bij de meeste voorkeur ca. 6450K bij een kleurweergave-index (CRI) van ten minste 80, bij meer voorkeur ten minste 90 en bij de meeste voorkeur ca. 98, wat gerealiseerd wordt met full spectrum daglicht. Zie voor de begrippen kleurtemperatuur en kleurweergave-index www.wikiwand.com/nl/Kleurtemperatuur resp. www.wikiwand.com/nl/Kleurweergave-index.The light produced by the lighting fixtures preferably has a color temperature of at least 5500K, more preferably at least 6000K and most preferably about 6450K with a color rendering index (CRI) of at least 80, more preferably at least 90 and most preferably around 98, which is achieved with full spectrum daylight. For the terms color temperature and color rendering index, see www.wikiwand.com/en/Color Temperature resp. www.wikiwand.com/nl/Color rendering index.
