Abstract
The utility model relates to a high-power electronic ballast which comprises two same ballast units which have independent functions; output ends of the two ballast units are respectively and independently connected with two lamp filaments of a fluorescent lamp; circuits of the two ballast units are arranged on a printed circuit board (PCB); and the PCB is provided with a mains supply input interface and a lamp filament output interface. By adopting the technical scheme, the high-power electronic ballast leads the two ends of a lamp tube to be charged and then discharged, and the lamp tube is lightened in the way, so that the service life of the lamp tube is improved.
Description
Technical field
The utility model belongs to electronic technology field, specifically is a kind of electric ballast that is used for fluorescent lamp.
Background technology
In the prior art, fluorescent lamp is widely used, but some shortcomings is also arranged because of its brightness power consumption ratio is high:
1, in actual life, fluorescent tube is used of a specified duration, and the pipe root can turn black, and break to filament to a certain degree, and fluorescent tube has just given up.Survey with universal instrument, the fluorescent tube that has has a filament still to be communicated with.As seen two filament suffered consumes in the same period are unequal, and the use of whole fluorescent tube just is affected useful life.
2, use history to see such process from fluorescent lamp, a period of time, be economize on electricity, the small-power fluorescent tube sells well very much.Now, people's living standard improves a lot, and the elderly's eyesight is aging in addition, and low power fluorescent tube light is obviously felt very dim, and demand has had variation, needs to use powerful fluorescent tube.Meanwhile, to the fluorescent lamp of illuminating 30W such as commerce, industry, institutional settings office or 40W, the general still Inductive ballast of usefulness, not energy-conservation.
The design production requirement height of high-power ballast, and along with power consumption improves, heat-energy losses is also very big, and along with power improves, it is more that cost improves.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of new electric ballast that is used for high-power fluorescent lamp, concrete technical scheme is as follows:
A kind of great-power electronic ballast comprises independently ballast unit of two identical, functions; The output of two ballast unit is two filaments of separate connection fluorescent lamp respectively; Described two ballast unit circuit are located on the same pcb board, are provided with civil power input interface and filament output interface on pcb board.
On described pcb board, described civil power input interface and filament output interface position are provided with the golden finger corresponding with standard sockets.
Described filament output interface has two or three.
Described two filament output interfaces connect the output of two ballast unit respectively.
In described three filament output interfaces, there are two filament output interfaces to connect the output of two ballast unit respectively, any one in the output of two ballast unit of the 3rd filament output interface connection.
General electric ballast from electronic circuit, is that the end to fluorescent lamp charges by electric capacity all the time, and then discharge, thereby lights fluorescent tube.The technical program makes the two ends of fluorescent tube all have an opportunity to charge and then discharge, and lights fluorescent tube with this mode, has improved fluorescent tube useful life.
Now with two independently capacitive character ballast use experiments in parallel.This method is lighted fluorescent lamp and be facts have proved through use and be fine.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
A kind of great-power electronic ballast comprises independently ballast unit of two identical, functions; The output of two ballast unit is two filaments of separate connection fluorescent lamp respectively; Described two ballast unit circuit are located on the same pcb board, are provided with civil power input interface and filament output interface on pcb board.
As shown in Figure 1, be to adopt two general ballast unit, these two same rectifier bridges of units shared, two ballast unit inversions are handled, and export to two filaments that connect fluorescent lamp respectively.
On described pcb board, described civil power input interface and filament output interface position are provided with the golden finger corresponding with standard sockets.The filament output interface can have 2 or 3.For 2 situation, be that the output that is used for two ballast unit connects 2 filament output interfaces respectively.For 3 situation, be that the output that is used for two ballast unit connects 2 filament output interfaces respectively; Another one filament output interface connects the output of any ballast unit, and the connection that is used for traditional approach is answered, and promptly connects two filaments simultaneously.
Like this, can modular this ballast of use.
As shown in Figure 2, on the edge of pcb board, be provided with and civil power input interface and the corresponding golden finger of filament output interface; Golden finger inserts in 15 slots of standard.On slot, also be provided with location notch.Simultaneously, the respective pin of slot connects the socket of two filaments of civil power and fluorescent lamp.On the edge of slot and pcb board, also be provided with corresponding positioning tooth.
A is that golden finger, b are that standard 15 slots, c are that the first filament output interface, d are that the second filament output interface, e are that positioning tooth, f are test interfaces among Fig. 2.
Fluorescent tube connects c point and d point, and this loop is a normal operating condition.The f point is to draw from the positive pole of rectifier bridge, and keeping somewhere the f interface is to judge loop between f point and the c point for test, or the loop has or not and opens a way or short circuit etc. has and do not damage usefulness between f point and the d point.
