[embodiment]

For above-mentioned purpose, the feature and advantage that make the utility model can be more obviously understandable, the embodiment of the utility model is done detailed explanation below in conjunction with accompanying drawing.A lot of details have been set forth in the following description so that make much of the utility model.But the utility model can be implemented much to be different from alternate manner described here, and those skilled in the art can do similar popularization under the situation of the utility model intension, so the utility model does not receive the restriction of following disclosed practical implementation.

See also Fig. 1 and Fig. 2, the LED module measurement jig 100 of an embodiment comprises pedestal 10, support 20 and portable plate 30.

Pedestal 10 is roughly square box body, and its end face offers a locating slot 11.Contain a PCBA positioning seat 13 through fixtures such as screws in the locating slot 11.PCBA jigsaw (figure does not show) can be fixed on the PCBA positioning seat 13.Through changing PCBA positioning seat 13, can realize fixing without the PCBA jigsaw of shape or single PCBA cell board.

Please consult Fig. 3 and Fig. 4 in the lump, the back side of pedestal 10 is provided with voltage input socket 15.In the present embodiment, voltage input socket 15 comprises leg-of-mutton high pressure input socket 151 and circular low pressure input socket 153.The front of pedestal 10 is provided with the high pressure input switch 171 of control high pressure and the low pressure input switch 173 of control low pressure.The front of pedestal 10 also is provided with a plurality of detection CSs 19.

Support 20 is roughly a vertical square plate, and it is fixedly set in the edge of pedestal 10 end faces.Support 20 is provided with a reometer 21 and a voltage table 23 near the position at top.The both sides of support 20 respectively are provided with a guidepost 25 vertical with pedestal 10.
