Abstract

The invention relates to fluorescent tube for use in a fluorescent tube lamp, wherein the fluorescent tube comprises a tubular body (1, 11) made of glass or plastic and a carrier strip (2, 12), on which a plurality of light-emitting diodes (3, 13) are mounted and which is pushed into the tubular body (1, 11), wherein the carrier strip (2, 12) has a bend (6) in the longitudinal direction, wherein the tip of the bend (6) is directed away from the housing (34, 43, 54) of the fluorescent tube lamp in the state in which the fluorescent tube is mounted in the fluorescent tube lamp, and the predominant quantity of the plurality of light-emitting diodes (3, 13) is disposed on the side of the carrier strip (2, 12) that is directed away from the housing (34, 43, 54) of the fluorescent tube lamp in the state in which the fluorescent tube is mounted in the fluorescent tube lamp.
