Abstract
A protector for a light tube, particularly an ultra
violet sun bed lamp or fluorescent lighting tube is made
of a flexible plastics material such as PVC, acrylic or
polyethylene and encloses the tube, making contact with
it at least at spaced positions, so as to contain any
glass fragments if the tube should shatter. Several
embodiments are described including the use of loose
polyethylene sleeve (l0) retained by circlips (l3) or an
extruded acrylic tube (l4) having internal ribs (l5)
providing partial spacing from the surface of the light
tube (ll), the acrylic sheath being extruded over sized
and shrunk onto the light tube by the application of heat
applied either externally or using the tube itself as a
heat source. In an alternative form, a flexible PVC
sleeve (l6) is expanded by compressed air so that the
light tube (ll) can be inserted, the sleeve then retur
ning to its normal size. In a further alternative, a
self-shrinking material such as cellulose is used in
extruded form, soaked in water to expand it onto the
light tube and dried to shrink onto the surface of the
tube.
