The invention relates to a flat discharge lamp (1) comprising two , substantially parallel plates (5 6) and two support areas serving to support both plates against each other. Each support area consists of a component having a high-viscosity (8) and a low viscosity (7) at assembling temperature. Before assembling the discharge vessel the support areas are larger than , final distance envisaged between both plates. The low viscosity component (7) compensates for possible local deviations in the distance between both plates when the discharge vessel are assembled.

Why it's free to use
- Filed April 9, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 9, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
