Sylvania MicroLynx 'F' Self-Ballasted Fluorescent

The radical MicroLynx 'F' lamp was conceived by SLI Lighting as a new light source primarily intended for domestic furniture lighting.  Traditionally low voltage halogen capsules are employed in this application, but their significant heat generation presents numerous safety hazards.  MicroLynx was therefore developed to deliver approximately the same light output as the small 10-20W halogen capsules found in this application, but without the heat.  To simplify its use in a domestic environment, a compact electronic ballast is included in the base area, thus the lamp can be driven direct from the mains electricity supply with no auxiliary gear.

At the heart of this engineering prototype lamp is a T2 (7mm diameter) narrow diameter fluorescent tube, which has been formed into a flat grid arrangement by the cut-and-kiss tube joining technique.  A preheated cathode resides at each end of the discharge path and is connected to a tiny electronic ballast in the rear half of the lamp.  A silvered disc separates these two elements, both to act as a reflector and direct light forwards, and also as a heat barrier to prevent overheating of the electronic ballast.  The discharge tube is contained within a polycarbonate cover having a prismatic texture, this serving to almost completely hide the shape of the fluorescent lamp hidden behind it.

Apart from the furniture lighting industry, the extremely low profile of this lamp lends itself well to numerous other applications.  For example, it can be surface mounted in luminaires so slim that they almost have the appearance of recessed downlighters.  The side-lighting of individual steps in a staircase is proving to be particularly popular application, as are pathway lights in exterior and garden environments.
