Abstract

The utility model provides a low voltage incandescent lamp electron energy saving device, which can convert the commercial power into the direct current power needed by a low-voltage incandescent lamp without using a transformer. The utility model comprises an AC voltage reducing circuit, a rectification circuit composed of a rectifier diode; a filter circuit and a voltage regulation circuit, wherein, the ac voltage reducing circuit is a voltage reducing capacitor which is connected in series with the rectification circuit of the rectifier diode. The both ends of the capacitor is connected in parallel with a discharge tube; a protective resistor is connected with the rectifier diode. The capacitor can be protected by the discharging of the discharge tube when the current is too great; the rectifier diode can not be broken down with the protection of the connected protective resistor. Because the transformer is omitted, the utility model has the advantages that the cost is low, the energy can be saved, and the luminous efficiency of the low voltage incandescent lamp is high.

Description

Low voltage incandescent lamp electron energy saving device

The utility model relates to and a kind of civil power is transformed to the required galvanic battery lamp Electronic energy saver of battery lamp.

At present civil power is transformed to adopt by what power transformer, rectification, filtering and voltage stabilizing circuit were formed of the required galvanic device of battery lamp more and becomes the stabilized voltage power supply of low-voltage DC by alternating current.This converting means makes its cost height because of adopting the transformer step-down, transformer power consumption itself, thereby power consumption is bigger.

Task of the present utility model provides and a kind ofly civil power is transformed to the required galvanic device of battery lamp, i.e. battery lamp Electronic energy saver without transformer.

Task of the present utility model is finished as follows; this battery lamp Electronic energy saver is a kind ofly to become the required galvanic stabilized voltage power supply of incandescent lamp by the 220V alternating current; it includes rectification circuit, filter circuit and the voltage stabilizing circuit of ac buck circuit, rectifying tube formation; it is characterized in that the ac buck circuit is a decompression capacitor that is connected on the rectifying tube rectification circuit; the electric capacity two ends are parallel with discharge tube, are connected to protective resistance on the rectifying tube of rectification circuit.

This Electronic energy saver just connects corresponding incandescent lamp according to output voltage, because the current break of electric capacity, discharge tube discharge prevention electric capacity when electric current is excessive, rectifier diode are connected to protective resistance can be not breakdown because of voltage jump yet.Owing to save step-down transformer, not only cost was low but also energy-conservation, and the luminous efficiency height.The incandescent lamp that adopts this energy-saving appliance and common 220V illuminating lamp are under the identical situation of brightness energy-conservation 50% to 60%.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is a kind of circuit diagram of the battery lamp Electronic energy saver that provides of the utility model;

Fig. 2 is the another kind of circuit diagram of the battery lamp Electronic energy saver that provides of the utility model.

In the accompanying drawings, the 220V civil power is through capacitor C 1 step-down, and the Y of discharge battalion that is connected in parallel on the C1 plays a protective role, and this circuit adopts by rectifier diode D ₁～D ₄The bridge rectifier that constitutes is in order to protect diode D ₁～D ₄, add protective resistance R ₁～R ₄Be attempted by on each diode, also can be at four diode D ₁～D ₄The diagonal angle on connect two protective resistance (see figure 2)s, by voltage-stabiliser tube DW voltage stabilizing, capacitor C ₂Filtering is through current-limiting resistance R ₅Output is for battery lamp D ₁Illumination is that the multiple of incandescent lamp rated voltage is several according to the voltage stabilizing output voltage, is connected in series several incandescent lamps, is advisable for general 1～3.
