PROBLEM TO BE SOLVED: To resolve some problems found in the conventional LED lamp that a weight of LED lamp of long straight type becomes heavy due to the fact that a configuration of arrangement of a supporting plate and a heat sink is essential in the straight pipe and it is hard to use it as a replacing product for a fluorescent lamp.SOLUTION: This invention provides a fluorescent LED lamp comprising a long glass pipe 0301 coated at its inner surface with fluorescent substance lit with ultraviolet rays and non-parallel ultraviolet LED element 0302 arranged at a lateral section of the long glass pipe with its optical axis being in non-parallel with a longitudinal central axis of the long glass pipe. Thus, even if the straight pipe is long, its weight is light, it can be used as a replaceable product for a fluorescent lamp and it becomes possible to provide a fluorescent LED lamp capable of attaining full surface light generation over 360 degrees in respect to a longitudinal central axis of the straight pipe.SELECTED DRAWING: Figure 3 |
