Description
Toename van lichtintensiteit van fosforescerende pigment door middel van licht uitkoppeling met holle glasparels.Increase in light intensity of phosphorescent pigment by means of light coupling with hollow glass beads.
Als wij lichtgevende pigmenten, bestaande uit de 5 chemische samenstelling, SrA1204: Eu, Dy, maar kan tevens bevatten een sulfide samenstelling, of gemaakt zijn van alkaline zeldzame aarde, of andere metalen zoals calcium, strontium, barium, of elk ander lichtgevend pigment dat in staat is om het zichtbaar licht terug te stralen in het 10 donker, droog of nat mengen in een industriële mixer of bijvoorbeeld een blender of op een andere wijze toevoegen binnen een productieproces, met holle transparante of halftransparante glasparels, ontstaat een compositie die bijdraagt om het licht dat het lichtgevend pigment in het 15 donker uitstraalt, optimaal uit te koppelen waardoor de lichtintensiteit van betreffende compositie in zowel een vloeistof of een vaste stof toeneemt.If we use luminous pigments consisting of the chemical composition, SrA1204: Eu, Dy, but may also contain a sulfide composition, or be made from alkaline rare earth, or other metals such as calcium, strontium, barium, or any other luminous pigment that is able to radiate the visible light back into dark, dry or wet mixing in an industrial mixer or, for example, a blender or add it in another way within a production process, with hollow transparent or semi-transparent glass beads, a composition is created that contributes to: to optimally couple the light that the light-emitting pigment emits in the dark, as a result of which the light intensity of the composition in question increases in both a liquid or a solid.
Dit resultaat is meetbaar en aanzienlijk, dit resultaat is zowel gemeten in vloeistoffen, als vaste 20 stoffen, ook als wij de lichtintensiteit van het lichtgevend pigment met de holle glasparels meten boven de vaste stof, of vloeistof of vloeibare stof meten wij een aanmerkelijke toename van de lichtopbrengst in het donker door middel van lichtkoppeling van bovengenoemd 25 lichtgevend pigment en de holle transparante of halftransparante glasparels.This result is measurable and considerable, this result is measured in both liquids and solids, even if we measure the light intensity of the luminous pigment with the hollow glass beads above the solid, or we measure a substantial increase in liquid or liquid the light output in the dark by means of light coupling of the aforementioned luminous pigment and the hollow transparent or semi-transparent glass beads.
I De lichtintensiteit van het afgegeven licht van de vloeistof, vloeibare stof of vaste stof waar, neemt toe.The light intensity of the light emitted from the liquid, liquid or solid substance increases.
Door de lichtuitkoppeling van de holle glasparel 30 ontstaat een toename van de lichtintensiteit van het licht dat het lichtgevend pigment in het donker uitstraalt.The light coupling of the hollow glass bead 30 results in an increase in the light intensity of the light that the light-emitting pigment emits in the dark.
Als wij de zojuist omschreven transparante of halftransparante holle glasparels vervangen door holle 102 9 2 91 2 parels gemaakt van onregelmatig transparant of halftransparant glas of indien wij de holle en transparante of halftransparante glasparels vervangen door holle parels transparante of halftransparante parels 5 gemaakt van plastic materialen zoals; PP,PE,PS,PA,PC,PVC, ABS,ΡΜΜΆ nemen wij een vergelijkbaar resultaat als omschreven in regel 4,5,6,7,8,9,10,11 blad 1.If we replace the transparent or semi-transparent hollow glass beads just described with hollow beads made of irregularly transparent or semi-transparent glass or if we replace the hollow and transparent or semi-transparent glass beads with hollow beads transparent or semi-transparent beads made of plastic materials such as ; PP, PE, PS, PA, PC, PVC, ABS, ΡΜΜΆ we take a similar result as described in rule 4,5,6,7,8,9,10,11 sheet 1.
Indien wij holle of massieve glas of andere parels mengen met metaalpigmenten zoals zilver, goud, aluminium, 10 chromium, aluminium, of een ander metaal, nemen wij ook een toename van de lichtuitkoppeling waar.If we mix hollow or solid glass or other beads with metal pigments such as silver, gold, aluminum, chromium, aluminum, or another metal, we will also notice an increase in light coupling.
Tevens zou ook besloten kunnen worden om deze metalenpigmenten te coaten met een transparante of halftransparante coating, van bijvoorbeeld liquid glas of 15 glas of PP,PE,PS,PA,PC,PVC,ABS,PMMA of andere half tranparante of transparante materialen, om deze vervolgens in te mengen met lichtgevende pigmenten als omschreven in conclusie 1.It could also be decided to coat these metal pigments with a transparent or semi-transparent coating, for example of liquid glass or glass or PP, PE, PS, PA, PC, PVC, ABS, PMMA or other semi-transparent or transparent materials, in order to subsequently mixing them with light-emitting pigments as defined in claim 1.
De zojuist omschreven methodes helpen om een 20 lichtkoppeling plaats te laten vinden die de lichtopbrengst van het lichtgevend pigment, zoals omschreven in conclusie 1,2,3,4,6,9,10,11 verbetert.The methods just described help to have a light coupling take place that improves the light output of the luminous pigment as described in claim 1,2,3,4,6,9,10,11.
Deze composities van holle transparante of halftransparante holle glasparels of solid parels kunnen 25 uitstekend verwerkt worden in vele toepassingen in plastic zoals plastic platen of master batches of films of folies of andere producten gemaakt van PP,PE,PS,PA,PC,PVC, ABS,PMMA of bijvoorbeeld verven en coatings inbegrepen poedercoatings, of inkten of glasobjecten, als toplaag in 30 keramiek en nog vele andere toepassingen.These compositions of hollow transparent or semi-transparent hollow glass beads or solid beads can be excellently processed in many applications in plastic such as plastic plates or master batches or films or films or other products made from PP, PE, PS, PA, PC, PVC, ABS Powder coatings, PMMA or, for example, paints and coatings, or inks or glass objects, as a top layer in ceramics and many other applications.
Daarnaast bemerkte wij dat de parels als omschreven in conclusie 1,2,3,4,9,10,11 ook met een dye the behandelen zijn, waardoor de originele kleur van het lichtgevend pigment als omschreven in conclusie 1,2,3,4,9,10,11 102 9 2 91 3 bestaat: uit het licht van het pigment en de gekleurde lichtuitkoppeling van de parels, de dye die wij gebruikt hebben is een tranparante of halftranparante fluoriserende dye, maar andere dyes kunnen ook gebruikt worden zolang 5 zij tranparant of halftranparant zijn.In addition, we noticed that the pearls as described in claim 1,2,3,4,9,10,11 can also be treated with a dye, whereby the original color of the luminous pigment as defined in claim 1,2,3,4 9,10,11 102 9 2 91 3 consists of: the light from the pigment and the colored light coupling from the beads, the dye we used is a transparent or semi-transparent fluorescent dye, but other dyes can also be used as long as 5 they are transparent or semi-transparent.
Ook kan het halftransparante of transparante pigment direct in de glas of andere parel als omschreven in conclusie 1,2,3,4 verwerkt worden.The semi-transparent or transparent pigment can also be processed directly in the glass or other pearl as described in claim 1,2,3,4.
Tevens is het mogelijk om de coating van het 10 lichtgevend pigment als omschreven in conclusie 1, van een fluoriserende dye te voorzien, onze ervaring is dat de helderheid van het licht van het lichtgevend pigment in het donker aanmerkelijk afneemt, onze voorkeur gaat dus . uit naar een tranparante en halftranparante dye of een van 15 toevoeging van transparante of halftransparante pigmenten in glasparels , bij voorkeur met een fluoriserende dye of pigment, op glas of andere parels als omschreven in conclusie 1,2,3,4.It is also possible to provide the coating of the luminous pigment as described in claim 1 with a fluorescent dye, our experience is that the brightness of the light of the luminous pigment in the dark decreases considerably, so our preference goes. looking for a transparent and semi-transparent dye or one of addition of transparent or semi-transparent pigments in glass beads, preferably with a fluorescent dye or pigment, on glass or other beads as defined in claim 1,2,3,4.
Hierdoor neem de helderheid van het licht verkregen 20 door lichtuitkopeling in de parel wel af, maar wordt wel een andere samengestelde kleur verkregen, deze combinatie bestaat dan uit het zichtbaar licht van het lichtgevende pigment als omschreven in conclusie 1 en de lichtkleur van het glas of andere parel, als omschreven in conclusie 25 1,2,3,4 verkregen door lichtuitkoppeling door middel van het gekleurd glas als zojuist omschreven en het lichtgevend pigment als omschreven in conclusie 1.As a result, the brightness of the light obtained by light excitation in the bead does decrease, but a different composite color is obtained, this combination then consists of the visible light of the luminous pigment as defined in claim 1 and the light color of the glass or another bead as defined in claim 1,2,3,4 obtained by light coupling through the colored glass as just described and the luminous pigment as defined in claim 1.
De andere methode willen wij wel vastleggen omdat dit ook een methode is om de kleur van het lichtgevend pigment 30 te beïnvloeden, voorheen gebruikte methode om lichtgevende pigmenten te kleuren waren het verwerken van het lichtgevende pigmenten en de kleur stof tijdens de bereidingswijze van het lichtgevend pigment, het kleur pigment werd dan vastgesmolten met hoge hitte aan het 1029291 4 lichtgevend pigment, een andere methode was om het pigment van een dye te voorzien met een halftranparante medium, bijvoorbeeld een inkt, bij beide methodes nam het licht van het lichtgevend pigment weg, het verlies in licht 5 bedroeg 20% tot 90% afhankelijk van de kleur, over het algemeen was het lichtverlies rond de 40%.We would like to establish the other method because this is also a method for influencing the color of the light-emitting pigment. Previously used method for coloring light-emitting pigments was the processing of the light-emitting pigments and the dye during the preparation process of the light-emitting pigment. the color pigment was then fused with high heat to the luminous pigment, another method was to dye the pigment with a semi-transparent medium, for example an ink, in both methods the light of the luminous pigment was removed, the loss in light 5 was 20% to 90% depending on the color, generally the light loss was around 40%.
Door gebruik te maken van gekleurde lichtuitkoppeling van glasparels en andere parels als omschreven in conclusie 1,2,3,4 is er geen verlies van lichtopbrengst 10 van het lichtgevende pigment als omschreven in conclusie 1.By using colored light coupling from glass beads and other beads as defined in claim 1,2,3,4, there is no loss of light output from the light-emitting pigment as defined in claim 1.
Er treed lichtverlies op bij de licht uitkoppeling van het licht in de gekleurde glasparel of andere gekleurde parels als omschreven in conclusie 1,2,3,4, tot op heden 15 hebben wij echter geen betere methode gevonden.Loss of light occurred with the light uncoupling of the light in the colored glass bead or other colored beads as defined in claim 1,2,3,4, but to date we have not found a better method.
Het verlies van lichtkoppeling in glasparels door middel van een halftranparante of tranparante dye kan ook als effect gebruikt worden als wij dit combineren met een thermografie pigment, een pigment of dye dat reageert op 20 temperatuur door zijn kleurstelling aan te passen, waardoor het of het lichtgevende effect blokt of juist doorlaat,doordat de reflectie van de achtergrond in kleur kan variëren, bijvoorbeeld naar zwart, zodat licht teruggave van het lichtgevend pigment als omschreven in 25 conclusie 1 bemoeilijkt wordt.The loss of light coupling in glass beads by means of a semi-transparent or transparent dye can also be used as an effect if we combine this with a thermography pigment, a pigment or dye that reacts to temperature by adjusting its color scheme, so that it or the luminous effect blocks or, on the contrary, transmits, because the reflection of the background can vary in color, for example to black, so that light return of the luminous pigment as defined in claim 1 is made more difficult.
