Abstract
The utility model discloses a light-emitting diode (LED) bulb lamp with a non-isolated power supply. The LED bulb lamp comprises the non-isolated power supply and LED lamp beads which are in electric connection with the non-isolated power supply and fixed on a bakelite printed circuit board (PCB). A printed circuit is arranged on one surface of the bakelite PCB, wherein the printed circuit is used for being in electric connection with the LED lamp beads and the non-isolated power supply. The other surface of the bakelite PCB is connected with an arranged radiator in a welded mode, and a soldering paste layer is arranged between the bakelite PCB and the radiator. The radiator is a lamp housing which is in a cylindrical structure, and a globe holder is arranged at the front end of the lamp housing. The LED bulb lamp with the non-isolated power supply has the advantages that a direct heat dissipation effect is achieved, the structural size of the LED bulb lamp is reduced at the same time, the non-isolated power supply can be adopted due to the insulation effect of the bakelite PCB, and heat dissipation sources are reduced. Compared with a traditional LED lamp with the same radiator size, the power of the LED bulb lamp can be improved by 50%-80%, the lighting effect can be improved by 20%-50%, and the luminous flux can be improved by 80%-200%.
