摘要:
An optical engine of a light emitting diode (LED) light module comprises a heat dissipation device, an LED light bar and an optical component. The heat dissipation device comprises a base plate and a plurality of fin plates vertically welded onto a surface of the base plate. The LED light bar is disposed on an opposite surface of the base plate so that the LED light bar can dissipate heat through the fin plates. The optical component having a space for accommodating the LED light is provided to form a desired light distribution pattern.

An LED lamp includes an illumination apparatus and a heat-dissipating waterproof cover. The illumination apparatus includes LED modules; and the heat-dissipating waterproof cover is configured to cover the LED modules. The heat-dissipating waterproof cover includes a plurality of drain members, and a gap is formed between every two drain members so as to increase the air convection, thereby increasing heat dissipation efficiency of the LED modules. Every two adjacent drain members are partially overlapping in vertical to prevent the intrusion of water.
