Abstract (en)
The present invention relates to an LED lamp that can be a direct replacement for an incandescent lamp and comprises a light-pervious bulb shell (1), a lamp cap (7) for connection to a lamp holder, at least one LED substrate (2) arranged inside the bulb shell (1), a drive circuit (8) connected to the LED substrate (2) and the lamp cap (7), a plurality of LED chips mounted on the LED substrate (2) in a manner that the LED chips are located in the vicinity of an inner surface of the bulb shell (1) and emit light towards a plurality of different directions. The heat generated by the LED chips is transferred directly to the outside of the bulb shell through the nearby light-pervious bulb shell (1), and also dissipated by a heat sink mechanism via both heat conduction and heat convection, achieving increased heat dissipation efficiency with a simple structure.
