Latest Patents

Van De Ven holds a patent for a low-pressure mercury vapor discharge lamp. This invention features a discharge vessel that encloses a discharge space containing a filling of mercury and a rare gas. The lamp includes an amalgam that communicates with the discharge space, which is designed to maintain an electric discharge. The amalgam composition is critical, comprising a Bi:Sn content in the range of 80:20 ≤ Bi:Sn ≤ 20:80, a Pb content between 0.7% and 12%, and a Hg content ranging from 0.05% to 2%. For compact fluorescent discharge lamps, the amalgam is optimized to include 70:30 ≤ Bi:Sn ≤ 30:70, 1% ≤ Pb ≤ 10%, and 0.25% ≤ Hg ≤ 1.2%. The lamp is noted for its high initial radiation output and short run-up time, achieving effective performance across a wide temperature range.
