Abstract
PURPOSE:To reduce the power consumption of a lamp by making its outer diameter have a specified length and sealing mercury and the argon having the specified sealing pressure in the bulb. CONSTITUTION:A bulb 1 has a phosphor coat 2 on its inner surface and opposed electrodes 3 and 3 are enclosed on both ends. A specified quantity of mercury is sealed inside this bulb 1. The circular fluorescent lamp with such structure has its outer diameters of 27-30mm. and seals argon as sealing gas. Its sealing pressure is specified as 1.5-3.0 Torr. This specification can reduce the power consumption of the lamp and eliminate its starting difficulty below the rated power voltage by combining an electron starter.
