Description of drawings
Among the figure,
The 1-electricity-saving lamp.
Embodiment
Embodiment; As shown in Figure 1; A kind of electricity-saving lamp is with double relay self-locking trigger control circuit; Comprise normal open switch EN1, normally closed switch EN2, diode D1, diode D2, diode D3, diode D4, three terminal regulator U1, relay K 1 and relay K 2, the model of three-terminal voltage-stabilizing is 7805 or 7812, and normal open switch EN1, normally closed switch EN2 are the soft-touch type key switch.
The termination control power supply of normal open switch EN1; The positive pole of another terminating diode D1 of normal open switch EN1; The negative pole of diode D1 connects the input of three terminal regulator U1, an end of the output relay termination K1 coil of three terminal regulator U1, an end of relay K 2 coils.
The termination control power supply of normally closed switch EN2, the positive pole of another terminating diode D2 of normally closed switch EN2, the negative pole of diode D2 is succeeded the fixed contact of electrical equipment K1.
The normally opened contact of relay K 1 connects the input of three terminal regulator U1; Diode D3 is connected the coil two ends of relay K 1; Diode D4 is connected the coil two ends of relay K 2; The other end ground connection of relay K 1 coil, relay K 2 coils, electricity-saving lamp 1 is connected on the mains supply through the normally opened contact of relay K 2.
After connecting normal open switch EN1, the input of three terminal regulator U1 gets electric, and the output output dc voltage is given the coil of relay K 1, relay K 2; The normally opened contact adhesive of relay K 1, relay K 2; Electric current is the input of the normally opened contact entering three terminal regulator U1 of switch EN2, diode D2, relay K 1 often, and the output output dc voltage is even unclamp normal open switch EN1; Because the self-locking of relay K 1 contact; Relay K 1 still is in attracting state, and the input of three terminal regulator U1 continues and normal power supply, and output continues to have voltage output.The normally open contact adhesive of relay K 2 is connected working power for electricity-saving lamp, makes it get into operating state.Press normally closed switch EN2, the input dead electricity of three terminal regulator U1, relay K 1, relay K 2 coil losing electricities, normally open contact breaks off, and electricity-saving lamp 1 dead electricity is extinguished.
The used components and parts of circuit are few, and cost is low, highly reliable; , relay is matured product, 100,000 times, 1,000,000 times, relay are widely applied, control flexibly; Easy to use, guarantee that circuit operates reliably and with long-term, can effectively solve the short problem of standard machinery formula switch life; Owing to use lower control voltage; So safe, guarantee that circuit operates reliably and with long-term, can effectively solve the short problem of standard machinery formula switch life.
Those skilled in the art will recognize that; Above-mentioned embodiment is exemplary; Be in order to make those skilled in the art can better understand the utility model content; Should not be construed as is the restriction to the utility model protection range, so long as the improvement of being done according to the utility model technical scheme, all falls into the protection range of the utility model.
