摘要： An illuminator has an elongate tubular body containing LEDs on a substrate and a lens forming a bridge over the LEDs. The tubular housing has a transparent top part to act as an outer lens and diffuser. The housing is connected at each end to an end cap via a resilient seal which is moulded into the end cap. The internal lens is compact and provides a versatile choice of illuminator configuration for desired illumination. A convex curved lower lens s profile ensures efficient transmission of emitted light without colour separation. The extent of sealing is very short due to the closed tube nature of the housing and the short perimeters for sealing of the ends of the body to the end caps.

摘要： A sanitizer has substrates which are coated with an optically-activated nanomaterial TiO2 coating for cleaning air which comes into contact with the surfaces of the coating. UV LED light sources are arranged to emit light to be incident on the surfaces to activate the coatings. There is a large surface for impingement of air on the coatings due to a grille arrangement of the substrates, and the LED-emitted UV light being incident at acute angles on the grille honeycomb structure.

摘要： A handle for a cabinet, has a translucent rod with a photocatalytic antimicrobial TiO2 external coating, and a pair of supports each engaging an end of the rod and being affixed to a cabinet door. One support has an array of two LEDs for emission of light into the rod, one LED emitting blue light and the other emitting white light. There is total internal reflection within the rod, for very effective incidence on the coating.
