Connecing between the positive terminal of device and negative pole end can be by wire jumper short circuit, between the positive terminal and negative pole end of first connector with wire jumper short circuit simultaneously
Ground connection, with wire jumper short circuit between the positive terminal and negative pole end of end connector；
Several fictitious load groups, there are one the fictitious load groups for concatenation between connector described in each two.
Optionally, each fictitious load group includes the bridge heap (bridge diode) that several are connected in series with.
Optionally, the bridge heap uses the electronic component of model US8KB80R.
Optionally, the first fictitious load group includes five bridge heaps being connected in series with, remaining each fictitious load group includes
Two bridge heaps being connected in series with.
Optionally, the pressure drop of each bridge heap is 1.4V.
Optionally, the connector number is 17, and the number of the fictitious load group is 16.
Optionally, it in addition to first connector, is connected in series between the positive terminal and ground of remaining each connector luminous
Diode and resistance.
Compared to the prior art, using the LED power aging testing jig of the present invention, in use, will need to carry out old
The LED power cathode for changing test connects first connector, the connector that the connection of LED power anode is chosen, the connection chosen
Respectively with wire jumper short circuit between the positive terminal and negative pole end of each connector between device and the first connector so that institute
It states the overall presure drop after each fictitious load string formation connection between the connector chosen and the first connector and is more than LED to be tested electricity
Source output voltage 80% and less than or equal to its output voltage.Since the LED power of the different output voltages of correspondence carries out aging
Test, it is only necessary to corresponding connector positive terminal is selected to be connect with LED power anode, and by the connector chosen with it is described first
Respectively with wire jumper short circuit between the positive terminal and negative pole end of each connector between connector, you can reach.Therefore, it only needs
A set of jig is the LED power burn-in test that may achieve different size, and design is simple, easy to operate；And it does not need to use water
Mud resistance, jig is small, light-weight；The use of light emitting diode can more detect whether LED power normally exports.

【Specific embodiment】
Referring to Fig. 1, Fig. 1 is schematically shown as the electrical block diagram of LED power aging testing jig of the present invention.
In order to achieve the above object, LED power aging testing jig provided by the invention, including：
Several connectors 100 are connected in series between each connector 100, and each connector 100 has positive terminal 101 and negative
Extreme 102, between the positive terminal 101 of each connector 100 and negative pole end 102 can by wire jumper short circuit, first connector 100
It with wire jumper short circuit and is grounded between positive terminal 101 and negative pole end 102, end is between the positive terminal 101 of connector 100 and negative pole end 102
With wire jumper short circuit；
Several fictitious load groups, between connector 100 described in each two concatenation there are one the fictitious load group, wherein,
Each each fictitious load group can be to include bridge heap 200 that several are connected in series with (please in conjunction with referring to Fig.2, Fig. 2 is schematically shown as
The electrical block diagram of a preferred embodiment of the present invention jackshaft heap), the bridge heap 200 is, for example, the electronics of model US8KB80R
Element, the pressure drop of each bridge heap 200 is 1.4V.
In the present embodiment, the first fictitious load group includes five bridge heaps 200 being connected in series with, remaining each fictitious load
Group includes two bridge heaps 200 being connected in series with.Described 100 numbers of connector are 17, and the number of the fictitious load group is 16
It is a.
Using the LED power aging testing jig of the present invention, in use, the LED power that progress burn-in test will be needed
Cathode connects first connector 100, the connector 100 that the connection of LED power anode is chosen, the connector 100 chosen and institute
It states between the positive terminal 101 of each connector 100 and the negative pole end 102 between first connector 100 respectively with wire jumper short circuit,
