(57) The invention provides a LED fluorescent lamp (10), comprising a lamp cap (800),
a bulb shell (100), a control circuit (600), at least two LED light sources (400),
at least two light source panels (300) on which the at least two LED light sources
are secured, respectively, heat-conducting means (500) and cover (700) means. The
heating-conducting means (500) comprises at least two thermally conductive base plates
which are disposed at an angle oblique to a longitudinal central axis of the heat-conducting
means, and on which base plates the at least two light source panels are secured in
a thermally conductive manner, the base plates extending downward from their bottom
ends to form a receiving chamber. The cover means (700) comprises a casing, and a
hollow barrel (710) for accommodating the control circuit, the casing is engaged snugly
with the heat-conducing means such that the heat-conducting means is coupled thermally
to the cover means. The cover means have a plurality of radiating fins (721) on its
outer surface. A path having good thermal conduction and thermal dissipation is created
along the light source panels - the heat-conducting means ― the casing of the cover
means ― the radiating fins. The LED fluorescent lamp exhibits excellent thermal conduction
and thermal dissipation to provide a solution to the problem associated with the thermal
dissipation of the LEDs.
