Abstract
The utility model relates to an inner core of a light adjusting base, which overcomes the defects that the inner core of a light adjusting base in the prior art has many devices, the circuit is complex, and the adaptive performance is poor. The inner core of a light adjusting base comprises a mouth tube and a connection end. A thyristor SCR is arranged between one of an electrode end C of the mouth tube and the B point of the connection end; both ends of the thyristor SCR are provided with an adjustable resistor W and a capacitance C connected in series; a trigger diode D is arranged between the connection point D of the adjustable resistor W and the capacitance C and the control pole F of the thyristor SCR. The utility model has the advantages of compact structure, small size, simple electronic circuit, and low cost, and is suitable for alternating current power supply with different voltages.
Description
The utility model relates to a kind of Dimming lamp socket inner core.
Existing Dimming lamp socket inner core is provided with light adjusting circuit between mouth tube and link, this light adjusting circuit as shown in Figure 4, its structure be adjustable resistance and capacitance series at the two ends of power supply, diac is connected between the electric capacity and the silicon controlled control utmost point, constitutes circuits for triggering thus.Because the silicon controlled trigger current has individual limiting value, this electric current is excessive, to puncture controllable silicon, and be directly to be connected on both ends of power during the work of this circuits for triggering, i.e. A, B 2 points, this voltage of 2 is very high, so be serially connected with current-limiting resistance at the adjustable resistance two ends, when preventing that adjustable resistance W from turning down gradually, the electric current that triggers the loop increases, and causes that trigger current is excessive and damages controllable silicon.When supply voltage not simultaneously, be 120 volts or 220 volts as supply voltage, not only to change the adjustable resistance of different resistances, and involve current-limiting resistance and also will become thereupon, make circuit conversion complexity.
The purpose of this utility model is to provide a kind of circuit structure simple, compactness, the Dimming lamp socket inner core of adaptation power source change.
For realizing the purpose of this utility model, described Dimming lamp socket inner core, comprise a mouthful tube, link, wherein be provided with controllable silicon SCR between the B point at described mouthful of one of them electrode tip C of tube and link, also there are the adjustable resistance W and the capacitor C of serial connection in the controllable silicon SCR two ends, are provided with diac D between the control utmost point F of the tie point D of adjustable resistance W and capacitor C and controllable silicon SCR.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model Dimming lamp socket core arrangement figure.
Fig. 2 is the utility model Dimming lamp socket inner core assembly structure figure.
Fig. 3 is the circuit theory diagrams of the utility model Dimming lamp socket inner core.
Fig. 4 is the circuit theory diagrams of original Dimming lamp socket inner core.
Below in conjunction with accompanying drawing, the embodiment of the utility model Dimming lamp socket inner core is described in further detail:
As shown in Fig. 1,2, the Dimming lamp socket inner core comprises the cylindric mouth tube (1) that has rib-loop, the link that links to each other with power line (2), be fixed on the circuit board (3) on mouthful tube (1), on circuit board (3), be provided with adjustable resistance W, capacitor C, controllable silicon SCR and diac D, link (2) is two stringing screws of A, B, is arranged on the circuit board (3).As shown in Figure 3, circuit board (3) is the double-sided circuit structure, its circuit connecting relation is wherein to be provided with controllable silicon SCR between the B point at described mouthful of tube (1) one of them electrode tip C and link (2), also there are the adjustable resistance W and the capacitor C of serial connection in the controllable silicon SCR two ends, between the control utmost point F of the tie point D of adjustable resistance W and capacitor C and controllable silicon SCR, be provided with diac D, constitute trigger control circuit thus controllable silicon SCR.Adjustable resistance W is a potentiometer, is provided with insulating trip (4) between potentiometer and the circuit board (3), and controllable silicon SCR is bidirectional triode thyristor SCR, and diac D is a bidirectional trigger diode.Work as rotational potentiometer, the resistance that makes it is from large to small the time, and the voltage of D, B point-to-point transmission rises, and the bulb that is contained in mouthful tube can brighten gradually; Otherwise the voltage between C, E descends, and bulb is deepening gradually, that is to say that trigger voltage changes with the resistance variations of potentiometer, and trigger current is also along with variation.Described adjustable resistance W has K switch, and its K switch is serially connected between the A point of mouthful tube (1) another electrode tip E and link (2), is convenient to control the on/off of entire circuit.Adopt double-sided PCB, potentiometer can be fixed on the one side of circuit board, controllable silicon SCR, capacitor C, diac D can be welded on the another side of circuit board, and adopt collapsible, controllable silicon SCR, capacitor C lie on the circuit board, make its compact conformation, whole assembly volume is little, is convenient to rivet with mouthful electrode of tube.Owing to saved current-limiting resistance, utilize bulb in the nozzle to carry out the current limliting electronic circuit and become simply, the voltage at the low eight bubble two ends of cost is steady, as long as the replacing potentiometer, just goes for 120,220 volts AC power, and this is that prior art is not accomplished.
The utility model is than prior art owing to adopt double-sided PCB, one of them electrode tip C of mouth tube with Link wherein is provided with controllable silicon SCR between the B point, controllable silicon SCR two ends and adjustable resistance W and electricity that serial connection arranged Hold C, between the control utmost point F of the tie point D of adjustable resistance W and capacitor C and controllable silicon SCR, be provided with triggering two Utmost point pipe D has compact conformation, and volume is little, and electronic circuit is simple, and cost is low, is suitable for the AC power of different voltages Advantage.
