A controllable LED lamp capable of emitting light in all directions comprises a lamp holder (1), a lamp body (2), and a lampshade (10). The lampshade (10) is in the shape of an inverted bowl. A plurality of vertical side cooling fins (7) is evenly disposed on the outer side of the lampshade (10). Side lamp beads (6) are mounted between the side cooling fins (7). A plurality of bottom lamp beads (11) is evenly disposed on the bottom sunken portion of the lampshade (10). Bottom cooling fins (8) are disposed between the bottom lamp beads (11). The bottom cooling fins (8) and the bottom lamp beads (11) are all mounted on a base plate. A light-pervious cover is disposed outside the base plate. The lamp body (2) comprises a heat dissipation layer (3) provided with a heat dissipation device and a circuit board layer (4) provided with a circuit board. A switch (9) controlling the side lamp beads (6) is disposed on the outer side of the lamp body (2). The lamp holder (1) is electrically connected to the circuit board, the switch (9), the side lamp beads (6) and the bottom beads (11). |
