Abstract
Disclosed is a device without a ballast and a starter, which can be used to start a fluorescent lamp normally for operation under the condition that voltage fluctuation is greater (100 volts to 240 volts). The utility model is electrically connected with a switch, capacitors, diodes and an inductor. The utility model is characterized in that a voltage-double rectification circuit is formed by the two capacitors and the two diodes; the input end of the voltage-double rectification circuit is electrically connected with the power switch; the positive pole output end of the power switch is electrically connected with one end of the inductor; an output end is formed by the negative pole output of the end of the power switch and the other end of the inductor.
Description
The utility model relates to a kind of device that makes fluorescent lamp normal starting and work under the situation of voltage fluctuation big (100-240 volt).
Starting of fluorescent lamp at present and work is generally by Inductive ballast with starter is common realizes that fluorescent lamp can't start when voltage is lower than 190 volts, thus limited the scope of application of fluorescent lamp, particularly in the use in vast rural area.
The purpose of this utility model provides a kind of under the very big or lower situation of voltage fluctuation, also the device that fluorescent lamp is normally started.
The purpose of this utility model is achieved in that in insulation crust, switch, electric capacity, diode, inductance and output line are electrically connected, two electric capacity and two diodes constitute voltage doubling rectifing circuit, its input is electrically connected with mains switch, its cathode output end is electrically connected with an end of inductance, and its negative pole output constitutes output with the other end of inductance.The input AC electricity obtains a high-voltage pulse electricity at output after voltage doubling rectifing circuit, be added to the fluorescent tube two ends again behind inductor filter, and it is luminous to make it build-up of luminance.The output voltage of the voltage-multiplying circuit among the present invention changes with the variation of load resistance.Fluorescent lamp belongs to the negative resistance load, prestart, and resistance is bigger, so circuit produces higher starting voltage with the starting fluorescent lamp, after the starting, the fluorescent lamp resistance decreasing is so that the operating voltage of lamp tube ends is tending towards automatically is normal.The utility model needs only with the combined use that just can satisfy the fluorescent lamp of different capacity of electric capacity, the inductance of different capabilities.
Advantage of the present utility model is simple in structure, use it to need not ballast, starter, open promptly bright, light and promptly go out, main is economize on electricity about 30%, prolonging lamp tube service life, the low pressure starting, dependable performance is so be specially adapted to big area of voltage fluctuation and long-term voltage small towns, rural area on the low side.
The utility model is as long as be contained in electric capacity, diode, inductance, switch etc. in the insulation box by designing requirement.
Description of drawings.Accompanying drawing is the utility model circuit theory diagrams.
Among the figure 1, power input line; 2, switch; 3, diode; 4, electric capacity; 5, inductance; 6, fluorescent lamp.
