The present invention discloses an LED module comprising: a waterproof enclosure; an LED accommodated in the waterproof enclosure; a wire for coupling the LED module with other LED modules and a driver; and a radiating unit set in the bottom of the waterproof enclosure and exposed to the external environment. The invention further provides an LED chain comprising the above said LED module and a driver coupled with the LED module. The LED chain according to the invention may have a high waterproof level, for example, IP65. The heat generated during the operation of the high power LED module may be transmitted to the external environment in time via a heat sink set on the LED module, thereby effective thermal management for the LED module and a long service life of the LED module may be obtained. Moreover, the finish surface of the driver may be made handsome by encapsulating the driver through the low pressure molding.
