The plug contact pin of LED lamp tube ends to be measured of take below snaps in the first deck 11 and the second deck 12 and packs test bracket 10 into and test as example, and the principle of work of the utility model LED fluorescent tube proving installation is specifically described:
According to Fig. 1 shown device, test controller 20 connects after test bracket 10 by five core sockets 27, by ac plug 26 incoming transport civil powers (AC220V), now the direct supply 22 in testing circuit module is started working, electric main is converted to low-voltage DC (DC12V), and constant output low-voltage DC, shown in Fig. 8 in circuit, during original state, change-over switch S1 is in off-state, the first relay K 1, the second relay K 2 and the 3rd relay K 3 are all in normally off, the fixed contact a1 of the first relay K 1 is connected with the normally closed contact a2 of the first relay K 1, the first fixed contact b1 of the second relay K 2 is connected with the first normally closed contact b3 of the second relay K 2, and the second fixed contact b2 of the second relay K 2 is connected with the second normally closed contact b5 of the second relay K 2, the first fixed contact c1 of the 3rd relay K 3 is connected with the first normally closed contact c3 of the 3rd relay K 3, and the second fixed contact c2 of the 3rd relay K 3 is connected with the second normally closed contact c5 of the 3rd relay K 3.
The second relay K 2 is in normally off when initial, therefore the low-voltage DC of direct supply 22 output terminal outputs is through the first fixed contact b1 of the second relay K 2, the first normally closed contact b3 exports respectively the first draw-in groove 111 on the first deck 11 and the first normally opened contact c4 of the 3rd relay K 3 to, simultaneously, the low-voltage DC of direct supply 22 output terminal outputs is through the second fixed contact b2 of the second relay K 2, the second normally closed contact b5 exports respectively the 3rd draw-in groove 121 on the second deck 12 and the second normally opened contact c6 of the 3rd relay K 3 to, be that a DC12V electric current part flows to the first draw-in groove 111 of the first deck 11 and the 3rd draw-in groove 121 of the second deck 12, DC12V electric current another part flows to the first normally opened contact c4 and the second normally opened contact c6 of the 3rd relay K 3.
The plug contact pin of LED fluorescent tube to be measured one end is vertically being snapped in to the first draw-in groove 111 and second draw-in groove 112 of the first deck 11, the plug contact pin of the LED fluorescent tube other end to be measured is vertically snapped in to the 3rd draw-in groove 121 and the 4th draw-in groove 122 of the second deck 12, LED fluorescent tube to be measured snaps in after first deck 11 and the second deck 12 of test bracket 10, the heat-dissipation aluminum sectional material of the first probe 14 and the second probe 15 contact measured LED fluorescent tubes also contacts well, and DC12V electric current enters LED fluorescent tube to be measured inside by the plug contact pin of LED lamp tube ends to be measured immediately.Now, if there is power supply short circuit in LED fluorescent tube to be measured inside, or conductor insulation sheath is crushed and wire touches heat-dissipation aluminum sectional material and causes leaky, DC12V electric current will flow to the first probe 14 and the second probe 15 by electric leakage contact point so, and through the first probe 14, the second probe 15, the first resistance R 1 flows to hummer BE1, hummer BE1 sounding alarm, simultaneously, DC12V electric current is through the first probe 14, the second probe 15, the second resistance R 2 flows to the anode of the first light emitting diode D1, the first light emitting diode D1 luminous alarm, there is leaky in the LED fluorescent tube of the current test of prompting tester, can not carry out next step operation (open test, light test operation), thereby avoid the life security that jeopardizes tester because of the electric leakage of LED fluorescent tube.On the contrary, if there is not power supply short circuit in LED fluorescent tube to be measured inside, or conductor insulation sheath is crushed and wire touches heat-dissipation aluminum sectional material and causes leaky, DC12V electric current will can not flow to the first probe 14 and the second probe 15 so, accordingly, hummer BE1 is sounding not, and the first light emitting diode D1 is not luminous yet, there is not leaky in the LED fluorescent tube of the current test of prompting tester, can carry out next step operation.
In the situation that hummer BE1 and the first light emitting diode D1 do not report to the police, change-over switch S1 is closed, the low-voltage DC (DC12V) of direct supply 22 outputs exports the coil of the first relay K 1 to through change-over switch S1, make the normal open switch of the first relay K 1 closed, the fixed contact a1 of the first relay K 1 is connected with the normally opened contact a3 of the first relay K 1, thereby, the low-voltage DC of direct supply 22 outputs is through the fixed contact a1 of the first relay K 1, normally opened contact a3 exports the coil of the second relay K 2 and the coil of the 3rd relay K 3 to, make the normal open switch of the second relay K 2 and the 3rd relay K 3 also closed, the first fixed contact b1 of the second relay K 2 and the first normally opened contact b4 of the second relay K 2 are connected, and the second fixed contact b2 of the second relay K 2 is connected with the second normally opened contact b6 of the second relay K 2, the first fixed contact c1 of the 3rd relay K 3 is connected with the first normally opened contact c4 of the 3rd relay K 3, and the second fixed contact c2 of the 3rd relay K 3 is connected with the second normally opened contact c6 of the 3rd relay K 3.Now, the electric main (AC220V) of external ac power source 30 outputs is through the first fixed contact c1 of the 3rd relay K 3, the first normally opened contact c4 exports respectively the first draw-in groove 111 of the first deck 11 and the first normally closed contact b3 of the second relay K 2 to, simultaneously, the electric main of external ac power source 30 outputs is through the second fixed contact c2 of the 3rd relay K 3, the second normally opened contact c6 exports respectively the 3rd draw-in groove 121 of the second deck 12 and the second normally closed contact b5 of the second relay K 2 to, thereby, an AC220V electric current part flows to the first normally closed contact b3 and the second normally closed contact b5 of the second relay K 2, AC220V electric current another part flows to the first draw-in groove 111 of the first deck 11 and the 3rd draw-in groove 121 of the second deck 12, to drive LED lamp tube starting to be measured.
In the situation that the 3rd draw-in groove 121 of the first draw-in groove 111 of the first deck 11 and the second deck 12 is connected electric main, if the plug T-shape sheet metal of LED fluorescent tube to be measured does not occur that screw from not being marked or screw are screwed to a phenomenon, the electric current flowing to so on the first draw-in groove 111 of the first deck 11 and the 3rd draw-in groove 121 of the second deck 12 flows to the second draw-in groove 112 of the first deck 11 and the 4th draw-in groove 122 of the second deck 12 by the plug T-shape sheet metal of LED fluorescent tube to be measured immediately, now, the second draw-in groove 112 of the first deck 11, the 3rd resistance R 3, the second light emitting diode D2, the 4th draw-in groove 122 of the second deck 12 forms loop, the second light emitting diode D2 is luminous, LED lamp tube starting, there is not screw from not being marked or the stubborn incomplete phenomena of screw in the LED fluorescent tube of the current test of prompting tester.On the contrary, if there is screw from not being marked or screw and twist incomplete phenomena in the plug T-shape sheet metal of LED fluorescent tube to be measured, be that open circuit phenomenon appears in LED fluorescent tube to be measured, the electric current flowing to so on the first draw-in groove 111 of the first deck 11 and the 3rd draw-in groove 121 of the second deck 12 will can not flow to the second draw-in groove 112 of the first deck 11 and the 4th draw-in groove 122 of the second deck 12, the second light emitting diode D2 is not luminous, LED fluorescent tube is not lighted, the LED fluorescent tube of the current test of prompting tester occurs that screw from not being marked or screw are screwed to a phenomenon, there is open circuit problem in the LED fluorescent tube that is current test, belong to substandard product.Thereby complete rapidly the test step of LED fluorescent tube, avoid underproof LED fluorescent tube to enter next process and cause potential safety hazard.
