Description
Technical field
The utility model relates to the fluorescent lamp technical field, is specifically related to a kind of electronic starter for fluorescent lamp.
Background technology
In a lot of local voltage at night phenomenons at the inclined to one side end that still exist, the fluorescent lamp that adopts the inductance type rectifier is opened Chang Buneng with conventional starter light fluorescent lamp at present.
The utility model content
Technical problem to be solved in the utility model is how a kind of electronic starter for fluorescent lamp is provided, and this starter can be lighted fluorescent lamp under the very low situation of voltage.
The technical problem that the utility model proposed is to solve like this: construct a kind of electronic starter for fluorescent lamp, it is characterized in that, comprise resistance-capacitance depressurization circuit, current rectifying and wave filtering circuit and delay circuit, wherein, the resistance-capacitance depressurization circuit connects current rectifying and wave filtering circuit, current rectifying and wave filtering circuit and delay circuit parallel connection; Described resistance-capacitance depressurization circuit is made of resistance R 5 and capacitor C 1 parallel connection, and described current rectifying and wave filtering circuit is made of bridge rectifier and capacitor C 2 parallel connections, and described delay circuit comprises that time-base circuit NE555, variable resistor RP, capacitor C 3, capacitor C 4 and K switch constitute.
According to electronic starter for fluorescent lamp provided by the utility model, it is characterized in that described bridge rectifier is by rectifier diode (VD1～VD4) constitute.
The utility model can be lighted fluorescent lamp to voltage is very low, and this product configurations is simple, and is safe and reliable, easy to install, not only one open promptly bright, but also life-span that prolonging lamp tube is used.
Description of drawings
Fig. 1 circuit structure diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model is formed resistance-capacitance depressurization by C1, R5, through VD1-VD4, C2 rectifying and wave-filtering, for NE555 provides 5V direct voltage, the time-delay break-make that the delay circuit that NE555 and RP, C3 form comes control relay is lighted fluorescent lamp after realizing turning on light several seconds by force.Its operation principle: behind the S that closes a switch, because the C3 both end voltage is zero, and 2,6 pin of NE555 are low level, 3 pin output high level makes relay coil energising, K switch adhesive, and this moment, starter was prepared in filament of fluorescent lamp energising preheating.Simultaneously, power supply charges to C3 by RP, through R, C after the time-delay several seconds 2,6 pin be high level, NE555 upset, i.e. 3. pin output low level, the relay coil dead electricity, the K switch open circuit, fluorescent lamp is lighted.
Main component parameter: R:420K Ω C1:0.047uF/630V C2:150uF C3:22uFC4:0.01uF RP:100k Ω potentiometer, just regulate RP to determine the starter delay time according to voltage.Relay 9V direct current relay.
The utility model also can be made various flexible mode, more than by embodiment by the accompanying drawing illustrated embodiment, be to further describing that foregoing of the present utility model is made, but this should be interpreted as that the scope of the theme that the utility model is above-mentioned only limits to described example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements and change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
