Definitions

  • the present invention relates generally to the field of antimicrobial lighting fixtures. More particularly, the present invention relates to mitigating or controlling bacterial growth in lighting fixture applications at healthcare facilities.
  • Silver is a powerful, natural antibiotic and is one of the oldest antimicrobial agents on record. Silver derives its broad spectrum antimicrobial activity from the ability of silver ions. Silver ions released from the antimicrobial agent, come in contact with microbes and the microbes are inhibited.
  • antimicrobial agents have been found to be useful blended with materials such as plastics, paintings and coatings, which also have applications in facilities such as hospitals.
  • antimicrobial agents have been adapted for incorporation within plastic, paint, and coating compositions to produce industrial, consumer and household products, which exhibit antimicrobial characteristics.
  • Various embodiments relate to antimicrobial functions for lighting systems and components.
  • Various embodiments relate to a lighting method and system with blended antimicrobial additives transferred onto micro-structured patterned surfaces for the purpose of reducing bacterial growth and maintaining a sanitary environment, for example, in a healthcare facility.
  • Still other embodiments provide a lighting system including lights, such as LED lights used, for example, in hospital LED lighting.
  • the lighting system includes components, such as a diffuser, made from antimicrobial material comprising a nano/micro-sized pattern surface.
  • the surface pattern is configured to diffuse light to create the required light distribution, such as Lambertian and Bat-wing etc.
  • Lambertian and Bat-wing etc. With the surface exhibiting a Lambertian distribution, for example, all incident light is scattered from the light source with the radiance being the same for all directions. Thus, the light falling is scattered such that the apparent brightness to an observer is the same regardless of the observer's angle of view.
  • the nano/micro structure surface pattern can be configured as either symmetric or asymmetric, depending on the lighting distribution requirements and appearance. Namely, the surface patterns can be applied uniformly, non-uniformly, (i.e., discontinuous) or geometrically, in particular in the form of symmetrical or asymmetrical patterns, distributed in a random or ordered way on the surface of the blended antimicrobial component. Regardless of the configuration of the surface patterns, this layer provides a functional pattern so as to provide the benefit of decreasing bio-adhesion between microbes and the substrate and preventing the growth of microbes.
  • One approach to reducing veiling glare is to place a diffuser in front of the light source. This lowers the surface luminance of the light fixture, but also reduces the loss of directional control of the light, which can result in veiling glare.
  • the present invention is capable of preventing bio-adhesion and providing optical veiling and diffusing effects to meet the light distribution requirements.
  • FIG. 4 depicts a method 400, also similar to the method 200 and including the step 210.
  • step 420 after antimicrobial additives are blended into a substance, this blend is applied to the surface of the lighting component.
  • the surface patterns is then formed by one of the known processes noted above.

Abstract

La présente invention concerne un système améliorant la régulation de la croissance bactérienne par la combinaison d'additifs antimicrobiens et de motifs de micro-structure de surface sur des surfaces extérieures d'un dispositif, tel qu'un appareil d'éclairage. Le système diminue physiquement la bio-adhésion entre des microbes et des substrats appliqués sur les surfaces extérieures. Ce système combine un composant micro-structuré de surface et un composant antimicrobien pour générer un composant unique.
