When the output voltage of the

pins

3 and 4 of the voltage stabilizing circuit U1 is higher than the output voltage of the pin 3.2V, NPN triode Q1, the collector of the triode Q1 is conducted to output low level and enters the power input end of the cathode of the relay J, the low level can also be subjected to voltage reduction and current limitation through the resistor R1 and enters the cathode of the light emitting diode VL1, and then the light emitting diode VL1 can be powered to emit light to give a prompt to a user, and at the moment, the output power of the voltage stabilizing. This novel change LED lamp pearl or voltage stabilizing circuit U1 of damage time, only need screw down lower cover 6, then take off cartridge type casing 3 and go up circuit board 11 respectively, just can conveniently change LED lamp pearl or voltage stabilizing circuit U1 of damage, in inserting two metal inserted bars 12 respectively in two 8 lower extremes of going up metal intubate after having changed, two metal inserted bars 14 insert two metal intubate 13 respectively down in, the internal thread screw in 5 lower extreme internal threads of lamp shade of lower cover 6, just can be to go up circuit board 11, cartridge type casing 3 from top to bottom installs once more in lamp shade 5. The resistance value of the adjustable resistor RP needs to be determined before production, when the resistance value is determined, the voltage stabilizing circuit U1 is converted into an output-adjustable AC-to-DC power supply module, two power supply input ends of a voltmeter and a control circuit are respectively connected to the power supply output ends of the voltmeter and the control circuit, then an adjusting handle of the AC-to-DC power supply is adjusted, the output power supply of the AC-to-DC power supply is enabled to be 3.2V, a debugging worker slowly adjusts the handle of the adjustable resistor RP, the adjusting purpose is achieved when an NPN triode Q1 is just switched on and a light emitting diode VL1 emits light, and the light emitting diode VL1 emits light when the output power supply of a U voltage stabilizing circuit 1 in the use of subsequent products is; then, a debugging person disconnects the power supply and tests the resistance value of the adjustable resistor RP, the measured resistance value is the curing resistance value of the adjustable resistor RP of all subsequent products (the resistance value of the adjustable resistor RP is directly adjusted in place in the subsequent production without testing), and the adjustable resistor RP can be replaced by a fixed resistor with the same resistance value in the actual production. The resistance value of the adjustable resistor RP is 4.7M; leds VL1, VL2 are red and yellow leds, respectively; the resistances of the resistors R1 and R2 are 160 omega; diode VD (VDN) type 1N 4007; relay J is a DC4100 model small 3V relay of the brand song. The utility model discloses can automatic disconnection a plurality of LED lamp pearls's input power supply after voltage stabilizing circuit output voltage is higher than 3.2V, prevent that LED lamp pearl from damaging because excessive pressure overflows, and when voltage stabilizing circuit output voltage is too high, give the user suggestion through first luminous of instructing emitting diode, when voltage stabilizing circuit damages not output voltage, only instruct emitting diode not give out light through the second and give the user suggestion, thereby the user can in time master the reason when whole LED lamp pearls do not give out light, in time change when voltage stabilizing circuit damages, the change speed has been improved.
