An LED lamp emitting light almost omnidirectionally comprises a lamp holder (1), an LED power supply (2), a cylindrical thin-wall LED light source (3), a lampshade (4), a metal connecting member (5), a metal heat dissipation member (6), and a flame-retardant-grade plastic connecting member (7). The LED power supply (2) is fixed in the flame-retardant-grade plastic connecting member (7). The flame-retardant-grade plastic connecting member (7) has an upper portion mechanically fixed with the lamp holder (1), and a lower portion mechanically fixed with the lampshade (4) by using the metal heat dissipation member (6). The metal connecting member (5) has one end fixed with the metal heat dissipation member (6), and the other end extending into the lampshade (4). The cylindrical thin-wall LED light source (3) is attached to an outer side surface of the part, extending into the lampshade (4), of the metal connecting member (5). The lamp holder (1), the LED power supply (2), and the cylindrical thin-wall LED light source (3) are electrically connected. The LED lamp has improved overall LED lamp heat dissipation capability, and alleviates the problem of the small emitting angle of the conventional LED bulb. |
