Abstract

PURPOSE:To decrease the mutual shielding effect due to tube bodies of a lamp and obtain a desired characteristic of the light distribution, by curving the tube bodies of the lamp in a plurality of planes intersecting each other. CONSTITUTION:In planes perpendicularly intersecting each other is curved a tube body 1 of the fluorescent lamp. At both ends of the tube body 1 are provided base parts 2. In this way, the tube body 1 of the lamp is curved in a plurality of planes intersecting each other capable of obtaining the fluorescent lamp with a large tube length without enlarging its height h.
