Abstract (en)
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 ۥ the casing of the cover means ۥ 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.
