An outer, light transmissive envelope surrounds the inner assembly and various fixing arrangements are disclosed for securing the inner assembly to the outer envelope. Three primary mechanisms are a ratchet mechanism, a spring mechanism, or using adhesive to secure the inner assembly to the outer envelope under a predetermined tension.
