The structural representation of the light-emitting diode light bar measurement jig 100 that Fig. 1 provides for one embodiment of the invention.This light-emitting diode light bar measurement jig 100 is used for light-emitting diode light bar 200 is carried out testing electrical property.
See also Fig. 2 and Fig. 3, in the present embodiment, this light-emitting diode light bar to be tested 200 comprises
substrate 21 and is arranged on a plurality of
light emitting diodes 22 on this
substrate 21, and these a plurality of
light emitting diodes 22 are located along the same line.
Light emitting diode 22 is encapsulating structure, comprises the structures such as light-emitting diode chip for backlight unit and transparent sealing.Each
light emitting diode 22 has a
positive pole 23 and a negative pole 24.Distance between the outside surface of the
positive pole 23 of each
light emitting diode 22 and the outside surface of
negative pole 24 is the length of this
light emitting diode 22
, the width of each
light emitting diode 22 is
