The electronic ballast is provided with a rectification circuit formed by four diodes in the bridge type connection. The voltage discrimination and operating state execution circuit is provided with a bidirectional controlled silicon TS. The bidirectional controlled silicon TS is connected with an intelligent sampling circuit G, and is formed into a bridge type or voltage multiplying rectification filter circuit with capacitances C1 and C2 and resistances R1 and R2 in the electronic ballast. The structure can adapt to the different power source voltages in each region of the present world, and can normally work in the region of the instable power source voltage. The utility model is increased with a small quantity of electronic elements, having low cost, high energy efficiency and reliable performance.
Description
Technical field the utility model relates to lamp, especially electricity-saving lamp.
The common electricity-saving lamp of background technology can only use under certain rated voltage as shown in Figure 1, will cause work undesired or burn when the range of nominal tension is used when surpassing.In order to adapt to the different supply power voltage in regions of the world, general electricity-saving lamp adopts the PWM-type electric ballast that has overvoltage, overcurrent protection, though its performance is good, and its complex circuit, the cost height, the user is difficult for accepting, and therefore is difficult to promote; Or adopt electronic ballast energy-saving lamp with the power regulator that limits supply voltage, as shown in Figure 2, its relative cost is low, when mains switch is closed, power supply is regulated by the electric energy of power regulator 2, overvoltage and superhigh pressure is limited in selected electric ballast 3 and fluorescent tube 4 both can be lighted, but again in the voltage range of trouble free service, yet because this power regulator is again to play regulating action by pressure limiting, therefore when supply voltage is higher, can produce a large amount of energy consumptions, especially during the supply voltage superelevation, energy consumption is bigger, does not reach the energy-conservation effect of electricity-saving lamp.
The summary of the invention the purpose of this utility model provides a kind of low energy consumption, low cost, and be applicable to the electricity-saving lamp of multiple supply voltage.
For realizing above purpose, the utility model is to adopt following scheme: electricity-saving lamp comprises power supply input circuit, voltage identification and operating state executive circuit, electric ballast and supporting fluorescent tube, electric ballast is provided with the rectification circuit that four diode bridge connect into, voltage identification and operating state executive circuit are provided with bidirectional triode thyristor TS, this bidirectional triode thyristor TS links to each other with intellegent sampling circuit G, and forms bridge-type or voltage multiplying rectifier filter circuit with capacitor C 1, C2, resistance R 1, R2 in the electric ballast.
The utility model electricity-saving lamp adopts the not mode of operation of deboost, be suitable for the wide 80V-280V that reaches of voltage, can adapt to each department, world today different electrical power voltage, also can be in the unsettled regional operate as normal of supply voltage, owing to only increase a spot of electronic component, cost is low, the efficiency height, dependable performance has the large market prospect.
Now the utility model is described in further detail in conjunction with the accompanying drawings for description of drawings:
Fig. 1 is the common energy-saving lamp working circuit diagram;
