Abstract
An ultrathin LED light engine (100) comprises a protective cover (106), a driving circuit board (101), an aluminum substrate (103) and at least one LED module (104). A double-sided high-viscosity heat conducting plate (102) covers the first surface of the aluminum substrate (103) to fix the driving circuit board (101); the at least one LED module (104) is fixed on the first surface and insulated from the aluminum substrate (103) by means of an insulating layer (200) on the first surface; a conductive circuit for electrically connecting the at least one LED module (104) and the driving circuit board (101) is arranged on the insulating layer (200); and the size of the aluminum substrate (103) at least at the local peripheral outer area is greater than that of the driving circuit board (101), so that the double-sided high-viscosity heat conducting plate (102) on the first surface at least locally fixes the protective cover (106). The LED light engine (100) 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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
