A LED lamp comprises a lamp-lid, a metal lamp-cup, an insulating layer for connecting a lamp-cap and the metal lamp-cup, and LEDs, a semispherical pallet or an astigmatism plate, and a PCB (Printed Circuit Board) in the metal lamp-cup, characterized in that , one semispherical pallet is provided on said PCB, the semispherical pallet has the same number of holes as that of the LEDs, the LEDs are installed in the holes of the semispherical pallet, electrical connections of the LEDs are connected to the PCB through the semispherical pallet, and provided with power. The LEDs installed in this way are mounted on the semispherical pallet and arranged in semisphere, thus light of the LEDs is radiated in various directions, increasing the light emitting angle of the LEDs, or the semispherical pallet is replaced by the astigmatism plate made of transmparent or subtransparent material, the said metal lamp-cup is a lamp-cup with larger area made of metal material, thus facilitating the heat emission of the LED lamp. |
