Abstract
PURPOSE:To obtain a fluorescent lamp having different phosphor layers on a semi- circumference basis per fluorescent lamp by a method wherein each of bulbs coated with different phosphor substances baked on each of them are divided into two portions in the longitudinal direction and two of the portions coated with different phosphor substances are combined into one body. CONSTITUTION:Each of glass bulbs, 1, 1' is coated with a daylight phosphor substance 2 and a warm white phosphor substance 3, respectively. The bulb is divided into halves in the longitudinal direction and separated. The divided halves of the bulbs 1, 1' are combined with each other and inserted into an external glass bulb 4 which is long and has a diameter slightly greater than that of the above combined bulb, of which both ends are fixed by means of binding metals. Next, mounts 7 provided with electrodes 6 each are attached to and sealed at both ends of the external glass bulb 4. By so doing, one fluorescent lamp is allowed to have different phosphor layers on a semi-circumference basis, so that illumination effects in either daylight or warm white color are made available by only turning the bulb by 180 deg..
