Description

Driver of daylight lamp

The utility model is a kind of fluorescent lamp driver, has the effect of starter and ballast concurrently.

Present fluorescent lamp provides starting resistor by starter when starting, provide operating voltage by ballast behind the fluorescent start.Starter only uses when fluorescent start, does not promptly re-use behind the fluorescent start.

The purpose of this utility model promptly is to design a kind of fluorescent lamp driver, and the starting resistor of fluorescent lamp is provided as starter when fluorescent start, and the operating voltage and the electric current of fluorescent lamp is provided as ballast behind fluorescent start.

The utility model comprises casing and the movement that is contained in the casing, movement by diode (D1) and (D2), electric capacity (C1) and (C2), and resistance (R) constitute, diode (D1) is connected in series with (D2), electric capacity (C1) is connected in series with (C2), the forward end of diode (D1) links to each other with electric capacity (C1), the negative end of diode (D2) links to each other with electric capacity (C2), resistance (R) input be connected on (D2) and (C2) between.

Diode (D1) and (D2), electric capacity (C1) and (C2) and resistance (R) constitute rectification, filtering and a voltage stabilizing circuit, resistance (R) also has the effect of current limliting simultaneously.

Compared with prior art, the utility model volume is little, in light weight, simple in structure, cost is low, have the double action of starter and ballast concurrently, and the safe and reliable life-span is long.Can be operated in 110～250V, can economize on electricity 30～50%.

Accompanying drawing is an embodiment of the present utility model.

Accompanying drawing 1 is the general structure cross-sectional schematic.

Accompanying drawing 2 is circuit theory diagrams.

Among the figure, 1 casing, 2 movements, D1 and D2 diode, C1 and C2 electric capacity, R resistance.

Each component parameters value is as follows:

D1、D2 IN4007；

C1、C2 2μF，450V；

R 150～200Ω，5W；

Below in conjunction with accompanying drawing, the utility model will be further described.

In this embodiment, the utility model comprises casing (1) and is contained in movement (2) in the casing (1), movement (2) by diode (D1) and (D2), electric capacity (C1) and (C2), and resistance (R) constitutes, diode (D1) is connected in series with (D2), electric capacity (C1) is connected in series with (C2), the forward end of diode (D1) links to each other with electric capacity (C1), the negative end of diode (D2) links to each other with electric capacity (C2), resistance (R) input be connected on (D2) and (C2) between, input power cord (A) and (B) be connected on respectively diode (D1) and (D2) between and electric capacity (C1) and (C2) between it, output line (C) and (D) be connected on resistance (R) output and (D1) and (C1) respectively.

In addition, (A), (B), (C), (D) four binding posts or binding post are housed on casing (1).This embodiment is the driver that is used for fluorescent lamp below 20 watts.

In use, before fluorescent lamp also is not activated after the energized, charge to electric capacity by diode, because volt voltage surplus can being charged to 300 on each electric capacity, voltage addition on two electric capacity, volt surplus the voltage at fluorescent lamp two ends finally is raised to 600, the fluorescent material in the fluorescent tube under high pressure are excited luminous and cause fluorescent lamp and be activated; After fluorescent lamp is activated, output line (C) and (D) between conducting voltage descend, the rectification filtering voltage stabilizing circuit that diode after this of the present utility model, electric capacity, resistance constitute is kept the work of fluorescent lamp for fluorescent lamp provides a stable pulse direct current operating voltage.

The parameter that this embodiment adjusts electric capacity and resistance promptly can be used for driving the fluorescent lamp of other various power.As electric capacity is replaced by 4.7 μ F, resistance is replaced by 300 Ω 8W promptly can be used for fluorescent lamp below the 40W.
