Beschreibung
Zusammenfassung:	The utility model relates to an LED street lamp. The LED street lamp comprises a copper substrate, an LED light source and a lamp shade, wherein the LED light source comprises a packaging adhesive layer and more than two LED chips, the LED chips are electrically connected with an external power supply through pins, the LED chips are connected with one another through bonding wires, and all the LED chips are packaged inside a groove on the upper surface of the copper substrate by the packaging adhesive layer. According to the LED street lamp, a plurality of chips are directly packaged on the copper substrate, and the heat is dissipated through the substrate directly, so that the manufacturing technology and cost of a support can be reduced, the cooling effect of reduction of the heat resistance is achieved, and the cooling effect of the LED street lamp is improved.
