Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
As shown in Figures 1 and 2, the light path converting module 13 that the embodiment of the present invention provides is applied in optical-fiber coupling connector 10 and is used for changing light path.
Optical-fiber coupling connector 10 also comprises circuit board 11, optical-electric module 12 and optical fiber 14 except comprising light path converting module 13, optical-electric module 12 is arranged on circuit board 11, light path converting module 13 be used for changing light the direction of propagation so that light between optical-electric module 12 and optical fiber 14, be coupled.
Optical-electric module 12 comprises light emitting diode 121 and photodiode unit 122, and light emitting diode 121 emits beam, and photodiode unit 122 is used for receiving light and is converted into electric signal.Light emitting diode 121 comprises one or plural light emitting diode, and photodiode unit 122 comprises one or plural photodiode equally.
Light path converting module 13 is being used for changing the direction of light between optical-electric module 12 and optical fiber 14 between optical-electric module 12 and optical fiber 14, light path converting module 13 comprises and being set up in parallel and two light pipe 13a that structure is identical.Can glue coating between light pipe 13a etc. resisting medium so that light pipe 13a combine closely.
Light pipe 13a comprises body 130, lays respectively at first lens 131 and second lens 132 at body 130 two ends and be positioned at the coating 133 on body 130 outside surfaces.
In alternate manner, the number of light pipe 13a in light path converting module 13 can equal the number sum of light emitting diode 121 and photodiode unit 122, i.e. each light emitting diode 121 and all corresponding light pipe 13a of each photodiode unit 122; Perhaps, light emitting diode 121 and photodiode unit 122 are total to same light pipe 13a.
