Beschreibung
Zusammenfassung:	The utility model discloses an LED lamp high in heat dissipation performance. The LED lamp comprises a lampshade, a thermal conductive plate, a radiator and an LED chip, wherein the radiator is installed on the lampshade, the thermal conductive plate is installed in a reflective cover, one side of the thermal conductive plate is connected with the radiator, the LED chip is installed on the other side of the thermal conductive plate, and the LED chip comprises a first support, a second support, adhesive with electrical conductivity, a PN joint, a sapphire and fluorescent powder. The LED lamp is characterized in that the first support and the second support serve as a P-type semiconductor and an N-type semiconductor respectively, the near end of the first support and the near end of the second support are coated with the adhesive with electrical conductivity, the two ends of the bottom of the PN joint are connected with the first support and the second support through the adhesive with electrical conductivity r
