    Abstract: A manufacturing method for a photoelectric package structure having a control chip is proposed. The photoelectric package structure concentrates light emitted therefrom, prevents external light interference and can be applied for advertising signs and backlight modules. Using the present invention increases the defect-free ratio and production quality. Applying the present invention for packaging light-emitting diode (LED) or optical sensor chips allows the necessary light-emitting requirements of electronic chips to be easily met. The package structure of the present invention is superior to conventional ones and the installation of the control chip doesn't reduce the light-emitting intensity. The major innovation of the present invention is disposing a photoelectric chip (or multiple photoelectric chips) on a control chip and then installing the control chip upon a substrate. Thus, installation-of the components is more convenient.
