Abstract
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.
