专利汇可以提供High pressure sodium lamp专利检索,专利查询,专利分析的服务。并且PURPOSE:To improve efficiency of a lamp by selecting proper conditions for operating the lamp and defining the length of electrodes. CONSTITUTION:End caps 2, 3 are fixed on the both ends of a luminous tube 1 made of light-transmitting polycrystal alumina, and electrodes 6, 7 or electrode conductors 4, 5 whose ends are provided with electrodes 6, 7 are fixed to these end caps. The internal volume of the luminous tube 1 is less than 2cm , in which sodium is charged together with a buffer metal. The ratio We/l of the wall load We(W/cm ) obtained by dividing the rated power fed into the luminous tube 1 by the internal surface of the luminous tube 1 between electrodes 6 and 7 to the shortest length l (cm) from the ends of electrodes 6, 7 on the discharging space side to the inner ends of end caps 2, 3 is adjusted to more than 40.,下面是High pressure sodium lamp专利的具体信息内容。
