INHERENTLY FLAME RETARDANT COMPOUND TO DIFFUSE VISIBLE LIGHT FROM FIXTURES CONTAINING LIGHT EMITTING DIODES AND PANELS MADE THEREFROM
Visible light actually emitted by a light emitting diode (LED) at a point source is perceived by a viewer of that LED to be sufficiently diffuse to hide the point source. A panel between the LED and the viewer is made from a mixture of polyvinyl halide polymer in a continuous phase and visible light refracting polymeric particles in a discontinuous phase. The polyvinyl halide has a refractive index different from the particles, and both have a different refractive index from air. Optical refraction causes the diffusion, providing "hiding power" to the panel, which is beneficially, inherently flame retardant because of the use of the polyvinyl halide as the continuous phase. Mixtures made with large visible light refracting polymeric particles can cause during profile extrusion randomly uneven surfaces to increase diffusion and reduce gloss.

To address the risk the outlet could become blocked in use, whilst avoiding the need to depressurize and/or stop the flow or polymer in extruder (19), the injection apparatus includes a spool (34) which is rotatably mounted within wall (35) of the extruder and is arranged to be rotated about an axis which extends substantially perpendicularly to the elongate extent of the extruder through which a polymer stream (18) flows. The spool may be moved between a first configuration and a second configuration wherein a flow path is interrupted, but wherein molten polymer continues to flow in said polymer flow conduit.
