An ultrathin LED light engine () comprises a protective cover (), a driving circuit board (), an aluminum substrate () and at least one LED module (). A double-sided high-viscosity heat conducting plate () covers the first surface of the aluminum substrate () to fix the driving circuit board (); the at least one LED module () is fixed on the first surface and insulated from the aluminum substrate () by means of an insulating layer () on the first surface; a conductive circuit for electrically connecting the at least one LED module () and the driving circuit board () is arranged on the insulating layer (); and the size of the aluminum substrate () at least at the local peripheral outer area is greater than that of the driving circuit board (), so that the double-sided high-viscosity heat conducting plate () on the first surface at least locally fixes the protective cover (). The LED light engine () realizes ultrathin design and built-in integration of drive and control devices, and realizes heat conduction and fixation of the PCB and the protective cover by using a double-sided high-viscosity film.
