Abstract
A light source device is disclosed and includes a reflective cup, a light-emitting chip, and a light transmissive substrate. The reflective cup has an opening. The light-emitting chip has a light-emitting layer, a first light-emitting surface, and a second light-emitting surface. The first and second light-emitting surfaces are opposite right to a first side and a second side of the light-emitting layer. The light-emitting chip is disposed inside the reflective cup, such that light emitted from the first and second sides emits out of the light-emitting chip through the first and second light-emitting surfaces respectively to be reflected by the reflective cup to be emitted out of the reflective cup through the opening. Therefore, the light extraction efficiency of the light-emitting chip can be improved.

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.
