Description

Integrated electronic ballast

The utility model relates to the integrated electric sub-ballast that a kind of fluorescent lamp uses.

Existing all kinds of fluorescent lamp ballast all selects for use a large amount of electronic component to form rectification circuit, delay control circuit etc., its weak point is a complex structure, poor stability during use, and be not suitable under water or adverse circumstances that acid-base value is high in work.

The purpose of this utility model designs a kind of simple in structure exactly, use reliable and stable, and the integrated electric sub-ballast that can in various adverse circumstances, work.

The purpose of this utility model realizes by following structure: the integrated electric sub-ballast, include current rectifying and wave filtering circuit, it is characterized in that: be connected to the integrated circuit JC01 that produces the built-in oscillation signal potential at the output of current rectifying and wave filtering circuit, be connected to a NC101 integrated circuit that is subjected to the power output excitation fluorescent lamp of its control at the output of JC01; Power supply produces built-in oscillation signal potential about 20,000 frequency 3V through input JC01 behind the current rectifying and wave filtering circuit during use, alternately controls NC101 power excitation fluorescent lamp work when defeated.

The utility model is owing to select for use two integrated circuits to replace a large amount of electronic components, thereby simple in structure, easily produce, and the fixing oscillator signal current potential of integrated circuit output, thereby use reliable and stable.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is enclosed construction figure of the present utility model;

Among the figure: 1 current rectifying and wave filtering circuit, 2 fluorescent tubes, 3 connect power end, 4 and connect fluorescent lamp two ends, 5 resin-encapsulated layers.

The utility model will be further described below in conjunction with drawings and Examples;

As shown in Figure 1: the utility model includes current rectifying and wave filtering circuit, be connected to the multivibrator JC01 that to produce the stream signal potential that fixedly shakes at the output of current rectifying and wave filtering circuit, be connected to an intermediate power amplifier NC101 integrated circuit model JD-1 who is subjected to the power output excitation fluorescent lamp of its control at the output of JC01; Can work under water or in the adverse circumstances sour, that basicity is higher in order to make the utility model, improve that it is anticorrosion, moistureproof, the performance of waterproof, acid-proof, alkali prevention, this ballast adopts the integrated seal structure that closes of resin solidification, at outer curing one deck resin envelope shape layer 5 of its electronic component printed panel etc., as shown in Figure 2.
