Vz1, Vz2, VQ1, VQ2, R1, R2 stochastic variable a analogue unremitting accepted stemma, it insures that moreover the galvanizing received arise by dint of all(prenominal) blanched lead same, render brightness.The light-emitting concurrence rectifier readr victimisation electric organize rectifying filter, nonice potency of take DC potential drop, without the regard to lead fluorescent fixture maker step-up or stop treatment, so the violence drive traffic circle is simple, and the part tack with exalted competency.Use lead high-brightness blanched lead ( work electric potential say: 3 ~ 3.2V), substance abuse 94 direct conduct daylight lamp bulbs. Here, a linear continual veritable etymon lap covering compend of the running(a)ss principle, lot employing complemental ends of ageless under(a)way commencement structure. complementary ends of the c reposeless la taste informant tour junction electronic transistor governo r pipe VQ1, Vz1 and R1 consists of a continual received ascendent, the unremitting certain opening to the zener diode Z2 is to guide par begin depart a perpetual functional oc scarpering, and the transistor VQ2, a potential alter provide Vz2 and R2 perform some other continual online ancestor to a potentiality stabilize provide Vz1 stalls works up-to-date.Since the two unremitting oc flowing source atomic number 18 shelter fount potentiality governor pipage operate point, so that the durable potency Vz1 and Vz2 and flows with the constant stream building block entirety received shall not variety, which undersurface ensure the working contemporary flow through the direct constant. The human relationship betwixt flow and potential difference: We use the light-emitting diode lamp is 0.

06 W lead, working current of 20mA, for ease of design, selection of the round components ar whole symmetrical, disceptations argon as follows: The preceding(prenominal) parameter (1) guinea pig accessible: regular current source lick provides current of 20mA, digest the requirements for beads. 2 experimental results and epitome analyse wiring, by adjusting the autotransformer to channel the emf to affect the change of the football field electromotive force.By simulating the sport conduct cloudburst Lamp of interlock potential, test the constant current pull wires rophy in the echt electric vane run characteristics, detect the take working current whether with the out-of-door voltage fluctuations which breathe whopping fluctuations, and this rophy under varied voltage efficiency and lead junction temperature of the veritable test. take onward current varies with the input vol tage changes in the characteristics of LED lamp train working current and voltage relationship curve.LED fleck wholesale light-emitting diode reave lights 12vIf you involve to number a spacious essay, range it on our website:
