11609 A light fixture has a support formed with a recess having an inner wall. An at least partially transparent lens covers the recess. A fluorescent tube in this recess is surrounded by a transparent and elastomeric cushion sleeve that is in turn covered by a rigid and transparent jacket, both made of synthet? -resin material. Elastomeric holding blocks are engaged betwee? the ?acket an the inner wall of the recess so as to support th? tube via the cushion sleeve and the jacket in the recess of the housing. Thus the tube is effectively protected against shocks of large and small amplitude over a wide frequency range. |
