METAL-HALOGEN LAMP Russian patent published in 2001 - IPC

Abstract RU 2165659 C2

FIELD: electrical engineering. SUBSTANCE: metal- halogen lamp has burner made of optically transparent material with electrodes sealed tight, lamp is filled with inert gas, with mercury in the amount from 0.0001 to 4.3 mg/cu m and with additives to provide burner with halogen-emitting metals of VIII group of periodic table of chemical elements in the amount from 0.0796 to 2.6 mg/cu m. Parameters of lamp are determined proceeding from following relation 9,14 ≥ jl/d2e

l×K·Pl/S ≥ 0,4, where Je is rated current of lamp, A; del is diameter of electrode bar, mm; Pe is power of lamp, W; S is area of surface of burner, sq mm; K is proportionality factor having value 1.0 and size mm4/A W. EFFECT: stabilized ultraviolet radiation flux in the course of service life of lamp. 1 dwg, 1 tbl
