Abstract

The utility model provides a Power transformer for a combination lamp, composed of an incandescent lamp and a daylight lamp. The utility model is formed by that two electrolytic condensers inversely connected in series according to polar phases is connected in series with a diode and a thermistor; the utility model can drives one route combination lamp or multiple routes of combination lamps each of which is formed by that an incandescent lamp and a daylight lamp are connected in series; the defects of high energy consumption and short service life of a lamp tube caused by a ballast and a starter are avoided. The utility model has the advantages of simple structure, convenient operation and low cost.

Description

The Assembled lamp supply convertor

The utility model relates to a kind of supply convertor, especially a kind of supply convertor that is used for the Assembled lamp be made up of incandescent lamp and sight lamp.

Can't drive many fluorescent tubes simultaneously at present existing fluorescent lamp ballast and starter, promptly a fluorescent tube need be joined a cover ballast and a starter, and existence makes lamp tube service life short, shortcomings such as energy consumption height, the applicant once designed a kind of Assembled lamp supply convertor, and applied for patent to Patent Office of the People's Republic of China, its patent No. is: 99216339.0, it can drive one or more simultaneously by an incandescent lamp and the Assembled lamp that fluorescent lamp composes in series, do not need to adorn starter and ballast in the circuit, avoided the fault that causes by ballast and starter, prolonged the useful life of light fixture and save electric energy.Because this supply convertor output voltage is a direct voltage, so when using this converter, also need install a two-direction switch in the circuit additional, in addition, also there is the circuit structure complexity in this Assembled lamp supply convertor, cost height, the shortcoming of complicated operation.

The purpose of this utility model is to provide a kind of and has above function equally, but structure is simpler, more convenient operation, Assembled lamp supply convertor that cost is lower.

Technical solution of the present utility model is: the Assembled lamp supply convertor constitutes by discharging and recharging partly to connect with rectification circuit, discharge and recharge part and be equivalent to an electrodeless electric capacity by the opposite serial connection of polarity by two electrochemical capacitors, each electrochemical capacitor all respectively and be connected to a diode, rectification circuit is made of a diode and a thermistor series connection.

The utlity model has following advantage: 1. do not need in the circuit to install two-direction switch again additional, structure is simpler, more convenient operation.2. during lamp works, can not produce fog in the pipe, use two can not turn black for a long time yet.3. lamplight brightness can change as required.As a 30W fluorescent tube and the combination of an incandescent lamp serial connection, fluorescent tube can be worked as 18W and be used to 45W, adds the power that incandescent lamp consumes, and is identical with traditional fluorescent lamp power consumption, and total brightness doubles.

Describe the utility model below in conjunction with accompanying drawing and implement structure.

Fig. 1 is the circuit diagram that the utility model is implemented structure.

Fig. 2 is the another kind of circuit diagram that the utility model is implemented structure.

Among Fig. 1, circuit by electrochemical capacitor C1 and C2 by the opposite serial connection of polarity after, be followed in series to form with diode D3, thermistor Rt, electrochemical capacitor C1 also is connected to diode D1, C2 and is connected to diode D2 and make protective circuit and use.

The utility model is implemented structure can also adopt circuit structure as shown in Figure 2, and its effect is the same.Among Fig. 2, electrochemical capacitor C1, diode D3, thermistor Rt and electrochemical capacitor C2 connect successively, and wherein, the connection of electrochemical capacitor C1 and C2 is opposite polarity, and on C1 and be connected to diode D1, C2 is last and be connected to diode D2 and make protective circuit and use.

Its operation principle is: alternating current 220V is added in the supply convertor input, capacitor charging and filtering ripple behind over commutation, if connect Assembled lamp at output, Assembled lamp is shinny when thermistor is opened a way, capacitor discharges and recharges in turn along with alternating current changes, and increases Assembled lamp two ends direct current numerical value and reduces gradually along with discharging and recharging several, reaches 0V at last, alternating voltage rises to 220V by 0V, discharges and recharges end light and settles out.

Claims

1. Assembled lamp supply convertor, comprise and discharge and recharge part and rectification circuit, it is characterized in that: discharge and recharge part and be in series with rectification circuit, wherein discharging and recharging part is made of by the opposite serial connection of polarity two capacitor C 1 and C2, on the capacitor C 1 and be connected to diode D1, on the capacitor C 2 and be connected to diode D2, rectification circuit is made of diode D3 and thermistor Rt series connection.
