## Abstract

An LED lamp with a built-in means of dissipating working heat includes top and bottom covers, a connector between the two, and an integrated device which is received by the top and bottom covers. The integrated device includes a radiator, a control circuit, and a plurality of LED chips. The control circuit and LED chips are disposed on the main surface and are electrically connected to the control circuit. One end of the connector is electrically connected to an external power source and the other end of the connector supplies power to the LED chips. The LED lamp being integrated with a radiator device, a control circuit, and an illumination device, the lighting efficiency and working life of the LED chip is improved.
