A LED energy-saving lamp comprises a housing of the energy-saving lamp, LED elements (10) and a power supply (20). The LED elements (10), a metal conductive layer (30) and the power supply (20) for the energy-saving lamp, which are electrically connected with each other, constitute a power supply circuit for the LED elements (10). In the case of the LED elements (10) being encapsulated LEDs, the LEDs are installed onto the metal conductive layer (30) by soldering or welding. In the case of the LED elements (10) being LED crystal chips, the LED crystal chips are installed onto the metal conductive layer (30).The heat radiating surface of the LED elements (10) is connected with one side of the metal conductive layer (30), an insulating layer (60) is arranged on the other side of the metal conductive layer (30), and a heat radiator (40) is set on the other side of the insulating layer (60).A transparent protecting glue (50) is arranged on the LED crystal chips. |
