Increased safety with luminaires

Especially interesting for
  • manufacturers of luminaires
  • applications in explosion protection

A new development made at PTB allows commercial T5 fluorescent lamps with higher power to be used in luminaires located in potentially explosive atmospheres. In the relevant zone, the hot spots at the surface of the spiral are safely enclosed, so that the surface temperature that is relevant from the point of view of explosion protection is reduced. This development takes not only the tolerance ranges of the T5 lamp diameters of different manufacturers into account, but also the spatial variation of the lamp's axis when the lamp is turned into place inside the socket as well as further degrees of freedom for safe use.
