Shown in Fig. 3 and Fig. 4, the present invention is divided into " full bridge rectifier " part and " constant-current circuit " part, is below " full bridge rectifier " part and " constant-current circuit " part specific works principle.
Full bridge rectifier principle: when X terminals 310 connect that power supply is anodal, Y terminals 320 are while connecing power supply negative pole, due to the unilateral conduction of rectifier diode, the flow direction of electric current is followed successively by X terminals 310, the first rectifier diode 370, some a, " constant-current circuit ", some b, the 4th rectifier diode 400, Y terminals 320; When Y terminals 320 connect that power supply is anodal, X terminals 310 are while connecing power supply negative pole, the flow direction of electric current is followed successively by Y terminals 320, the 3rd rectifier diode 390, some a, " constant-current circuit ", some b, the second rectifier diode 380, X terminals 310.Like this, regardless of the polarity of powering, the inner direction through " constant-current circuit " is always an a to putting b.
Constant-current circuit principle: as described in " full bridge rectifier principle ", the voltage of point a is forever for just, the voltage of point b is forever for negative, when electric current flows through the second resistance 360, the 5th rectifier diode 410, the 6th rectifier diode 420 successively from an a, due to the pressure drop that rectifier diode produces when the conducting, will will produce the voltage of a 1.4V at a c; This voltage is by will producing the voltage of a 0.7V after triode 330 at a d, the voltage of this 0.7V will be constant by 330, triode, and not be subject to the impact of supply power voltage; The electric current that note flows through the first resistance 350 is i4, and this electric current is because the voltage perseverance of a d is 0.7V, and the resistance value of the first resistance 350 is fixed, so i4 also immobilizes; The size of i4 electric current is the current i 3 and current i 2 sums that flow through triode 330 emitters that flows through light-emitting diode 340, and due to the amplification of triode 330, make i4 be far longer than the current value of i2, so i2 can be left in the basket conventionally, the size of current of i3 equals the size of current of i4; In sum, the current i 3 that flows through light-emitting diode 240 can keep constant, not affected by supply power voltage, has completed the function of constant current.
Shown in Figure 2, the present invention in use connected mode is identical with traditional plug, and service cable is connected directly on circuit board, by circuit board, power supply is connected in parallel on Connection Block, and Connection Block is connected on electrical appliance socket again and powers to electrical appliance.
Operating mode one: when the voltage that is applied to X terminals 310 is for just, the voltage of some Y is when negative, and the circuit on circuit board makes it luminous by power-supply rectifying, constant current rear drive light-emitting diode.
Operating mode two: when the voltage that is applied to X terminals 310 is for negative, the voltage of Y terminals 320 is timing, and whole process is with operating mode one.
Operating mode three: in the time being applied to X terminals 310 and being alternating current with the voltage of Y terminals 320, whole process be operating mode one and operating mode two fast alternately.
In the time that power supply is cut off, circuit board loses power supply, and light-emitting diode extinguishes.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
