Abstract

The invention discloses a photoelectric conversion module which comprises a main circuit board and an optocoupler. The main circuit board comprises a bearing surface. The photoelectric conversion module further comprises a sub-circuit board. The sub-circuit board is vertically fixed on the bearing surface and is electrically connected with the main circuit board. The sub-circuit board comprises afirst surface perpendicular to the bearing surface. A number of photovoltaic elements are arranged on the first surface. The optocoupler is provided with a number of first coupling lenses and is fixedon the first surface of the sub-circuit board. Each first coupling lens is aligned by corresponding to a photoelectric element. The photoelectric conversion module provided by the invention has the advantage of easily light path alignment.

Description

[0001] This application is a divisional application of a patent with an application number of 2012104228677 and an application date of October 30, 2012, and an invention titled "photoelectric conversion module". technical field [0002] The invention relates to a conversion module, in particular to a photoelectric conversion module. Background technique [0003] The photoelectric conversion module is used to connect the optical signal transmitting device and the optical fiber or between the optical fiber and the optical signal receiving device to realize the coupling of the optical signal and the mutual conversion between the optical signal and the electrical signal. Existing photoelectric conversion modules are used to bend the surface-emitting laser by 90 degrees to transmit energy to the optical fiber, or to bend the light transmitted by the optical fiber by 90 degrees to be received by the photodetector. The photoelectric conversion module is usually realized by using a ...
