METAL HALOGENIDE LAMP Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: metal halogenide lamp has burner of quartz glass with hermetically sealed electrodes. Burner is filled with mercury, gallium, lead, aluminium, magnesium and iodine with following molar concentrations of metal ingredients filling volume of burner, μmole/см³: mercury 5.9-29.5; gallium (0.09-0.6), lead (0.03-0.5), aluminium (0.01-0.2), magnesium (0.02-0.3). Ratio of molar concentration of iodine in terms of atomic iodine to sum of molar concentrations of gallium, lead, aluminium and magnesium amounts to 1.1-2.6. EFFECT: increased operational efficiency and stability. 1 tbl
