Abstract

An LED lamp comprises an LED light source (1), a cup-shaped radiator (2) and a power supply (3), electrodes (1a) and a heat sink (1b) are provided at the back side of the LED light source (1). The LED light source (1) is provided at the inner side of the bottom of the cup-shaped radiator (2), electrodes (7) are provided at the bottom of the cup-shaped radiator (2). The power supply (3) is provided at the outer side of the bottom of the cup-shaped radiator (2). The electrodes (1a) of the LED light source (1) and the power supply (3) are directly connected with two ends of the electrodes (7) of the cup-shaped radiator (2) respectively. A manufacture method of the LED lamp is also provided. The heat-conduction efficiency of the LED lamp is high, and the heat-dissipation structure of the whole lamp is effectively improved. And heat is dissipated by radiating, and therefore the stability in the indoor illumination environment is high. The manufacture process has high automation degree.
