Abstract
The utility model provides a power transformer for a combined lamp composed of an incandescent lamp and a daylight lamp. The utility model is characterized in that one end of a rectifying circuit made of full-wave rectifying silicon stacks is connected to an AC power supply; the output end is connected to a filter circuit composed of capacitors; one end of a control element thermistor is connected to a phase wire of the AC power supply, and the other end is connected to a midpoint of the filter circuit; the output end of the power transformer is connected with a one-path or multipath combined lamp formed by the method that a filament lamp and a daylight lamp are connected in series. The utility model is used for avoiding the defects that high energy consumption caused by a ballast and a starter shortens the service life of a lamp tube, etc.
Description
The utility model relates to a kind of electric power conversion apparatus, especially a kind of supply convertor of the Assembled lamp of being made up of incandescent lamp and fluorescent lamp.
Traditional fluorescent lamp Inductive ballast, starter and the electric ballast that occurred afterwards, generally all exists make fluorescent tube useful life short, energy consumption is high, circuit structure is complicated and a fluorescent tube need be joined one and overlapped the defective that accessory promptly can't be lighted many fluorescent tubes.
At above shortcoming, the utility model provides a kind of supply convertor, it can drive one or more by an incandescent lamp and the Assembled lamp that fluorescent lamp is concatenated into, and has avoided the fault that caused by ballast and starter, can prolong the useful life of light fixture and save electric energy.
The utility model is achieved in that it comprises rectification circuit, control circuit and filter circuit, directly receive the AC power end by the rectification circuit that the full-wave rectification silicon stack constitutes, its output is received in the filter circuit of being made up of electric capacity, control circuit is a thermistor, it one terminates on the phase line of AC power, and the other end is connected on the mid point of filter circuit.
The output of supply convertor can connect one or more by an incandescent lamp and the Assembled lamp that fluorescent lamp is concatenated into.
Use this Assembled lamp supply convertor, do not need to use in addition ballast or starter, thereby avoided for example burning out filament easily and making the shortcoming that lamp tube service life is short, energy consumption is high by what they brought, incandescent lamp and fluorescent lamp are serially connected in the circuit, the heat energy that produces in the annex can be become luminous energy, increase the brightness of light, saved electric energy.
Below in conjunction with accompanying drawing the utility model embodiment is described.
Fig. 1 is a circuit diagram of the present utility model.
Among the figure, the full-wave rectification silicon stack of being made up of diode D1, D2, D3 and D4 constitutes rectification circuit, its input is received the AC power end, output is received in the filter circuit of being made up of one group of capacitor C 1 and C2, automatic control circuit is a thermistor Rt, it one terminates on the phase line of AC power, and the other end is connected on the mid point of filter circuit.Output at supply convertor can connect one or more by an incandescent lamp and the Assembled lamp that fluorescent lamp is concatenated into, and present embodiment connects one the tunnel.Connecting alternating current moment, when the A point was positive half cycle, diode D1 conducting was charged to C1, and during negative half period, diode D4 conducting is charged to C2, and output voltage is
Direct voltage, this voltage directly is added in the fluorescent lamp two ends, and it enough makes fluorescent lamp excitation and luminous.After fluorescent lamp is luminous, there is electric current to pass through incandescent lamp, make the tungsten filament combustion extremely incandescent and luminous, this moment, circuit was got back to normal operating conditions automatically, when the A point is positive half cycle, D1 and D3 conducting, and to C1 and C2 charging, during negative half period, D2 and D4 conducting, to C1 and C2 charging, output voltage is after the rectification
220V=311V, it is kept Assembled lamp and continues shinny.
For making the utility model cost is that economy is durable again, and rectification silicon stack is withstand voltage should to be chosen in more than the 800V, and filter capacitor is selected withstand voltage more than 400V, and the control element thermistor is withstand voltage also should to be chosen in more than the 400V.
Claims (2)
1. Assembled lamp supply convertor, comprise rectification circuit, control circuit and filter circuit, it is characterized in that rectification circuit is made of the full-wave rectification silicon stack, and receive the AC power end, its output is received in the filter circuit of being made up of electric capacity, and the automatic control circuit one that is made of thermistor terminates on the phase line of alternating current, and the other end is connected on the mid point of filter circuit.
2. Assembled lamp supply convertor according to claim 1 is characterized in that connecting one or more by an incandescent lamp and the Assembled lamp that the fluorescent lamp serial connection forms at the output of Assembled lamp supply convertor.
