Abstract

PURPOSE:To make a metal halide lamp high efficient as wel as make its starting easier by forming the inner turn of two-layered coil into a roughly wound structure and also by properly designating the relation between the filament diameter of primary and secondary coils of the two-layer coil and the winding pitch of the inner turn of the two-layered coil. CONSTITUTION:The heat-resistant, light-permittive luminous tube 2 is filled with an inert gas for starting, mercury, and a metal halide. The electrodes 3 and 3' are made up by winding a double coil around a pole core in two layres so that the inner turn of the two-layered coil is roughly wound. In this case, the diamteter D of the electrode pole core is set up to satisfy the relationship, O<d2/d1<=0.6(L/d3-1) and d3<L<=3d3, where d1 is the filament diameter of the primary coil of the double coil, d2 is the filament diameter of the secondary coil, d3 is the diameter of double coil consisting the primary coil and the secondary coil, and L is the winding pitch of the inner turn of the two-layered coils of double coil.
