Abstract

The utility model discloses an LED fluorescent lamp circuit comprising an AC power supply, a ballast filter module, a rectifying module, a filter module and an LED load which are connected in sequence. As the fluorescent lamp circuit adopts an inductive ballast of the existing traditional fluorescent lamp, the LED fluorescent lamp circuit does not need to modify the original circuit when the LED fluorescent lamp is installed, simplifies the installation process of the lamp, and can be directly installed and used; and simultaneously, the LED fluorescent lamp circuit does not need to produce electronic ballasts, can directly adopt the inductive ballast in the installing seat of the traditional fluorescent lamp, save the production and manufacture costs, and can really realize general matching and general use of the LED fluorescent lamp and the traditional fluorescent lamp.

Description

A kind of LED daylight lamp circuit

[affiliated technical field]

The utility model relates to a kind of daylight lamp circuit, refers in particular to a kind of LED daylight lamp circuit.

[background technology]

LED as the 4th generation lighting source begin to enter common lighting field with its advantages of energy saving and environmental protection, be the approval that the house illuminating product of representative has obtained market with LED daylight light fixture.Existing fluorescent lamp divides electronic ballasting and inductance type ballast, and LED daylight light fixture product all adopts is electric ballast, this makes also must rectify and improve original circuit when adopting LED daylight light fixture to change traditional daylight light fixture, change electric ballast, this has caused inconvenience for installing and using of LED daylight light fixture, and the electric ballast cost of manufacture is higher than Inductive ballast far away, the manufacturing cost of light fixture itself is increased, so people are badly in need of the LED daylight lamp circuit that a kind of cost of manufacture is cheap, be convenient to change traditional inductance type fluorescent lamp.

[utility model content]

In order to solve the problems of the technologies described above, the purpose of this utility model is to provide the LED daylight lamp circuit that a kind of cost of manufacture is cheap, be convenient to change traditional electrical minor fluorescent lamp.

The utility model is that to reach the technical scheme that above-mentioned technical purpose adopts be a kind of LED daylight lamp circuit, it is characterized in that this circuit comprises AC power supplies, ballast filtration module, rectification module, filtration module and the LED load that connects successively.

The utility model beneficial effect compared with prior art is: because daylight lamp circuit of the present utility model has adopted and the identical Inductive ballast of existing traditional fluorescent lamp tool, when being installed, LED daylight light fixture need not to rectify and improve original circuit, simplified the lamp installation process, can directly install and use; Need not to produce electric ballast simultaneously, can directly adopt the inductance rectifier in the traditional fluorescent lamp tool mount pad, saved and manufactured cost; The wildcard that can really realize LED daylight light fixture and traditional fluorescent lamp tool by this circuit is general.

Preferably, described LED load is composed in series by a plurality of LED luminescence units, and described LED luminescence unit comprises LED module and voltage stabilizing didoe, described LED module and voltage stabilizing didoe reverse parallel connection.

Preferably, described LED module comprises at least two LED that are connected in parallel.

Preferably, described filtration module comprises the filter resistance parallel with one another and second filter capacitor.

Preferably, described ballast filtration module comprises a ballast inductance and first filter capacitor that is connected with the ballast inductance.

Preferably, also be in series with first voltage stabilizing didoe between described rectification module and the filtration module.

Fig. 1 is the structured flowchart of the utility model circuit.

Fig. 2 is the schematic diagram of the utility model circuit.

[embodiment]

In order more clearly to introduce the utility model, circuit structure of the present utility model is done further detailed description below in conjunction with accompanying drawing.

As shown in Figure 1, circuit of the present utility model comprises connection successively: AC power supplies S, ballast filtration module W, rectification module B, filtration module E and LED load F.

As shown in Figure 2: circuit of the present utility model comprises AC power supplies S, and live wire L that is connected with AC power supplies S and zero line N, live wire L connect the first filter capacitor C1 that is connected in parallel behind the ballast inductance L1 between live wire L and zero line N; The first filter capacitor C1 is mainly used to filter the clutter that exchanges end, and the ballast inductance L1 and the first filter capacitor C1 constitute ballast filtration module W; After the first filter capacitor C1, connect a rectifier bridge Q, live wire L is connected with the first input end a of rectifier bridge Q, zero line N is connected with the second input c of rectifier bridge Q, the negative pole end d of described rectifier bridge Q connects ground connection behind the first voltage stabilizing didoe D1, and the described rectifier bridge Q and the first voltage stabilizing didoe D1 constitute rectification module B; The cathode output end b of described rectifier bridge Q connects the second voltage stabilizing didoe D2, and the output of the described second voltage stabilizing didoe D2 connects filtration module E; This filtration module E comprises the filter resistance R parallel with one another and the second filter capacitor C2, and the described second filter capacitor C2 adopts electrochemical capacitor, the output connection LED of filtration module E load F, the negative pole end ground connection of described LED load F; Described LED load F is composed in series by a plurality of LED luminescence unit G, described LED luminescence unit G is made up of reverse parallel connection LED module M and voltage stabilizing didoe D together, described LED module M comprises at least two LED that are connected in parallel, above-mentioned voltage stabilizing didoe D has the effect of by-path turn-on, from having improved the service efficiency of entire circuit.

Because daylight lamp circuit of the present utility model has adopted and the identical Inductive ballast of existing traditional fluorescent lamp tool, when being installed, LED daylight light fixture need not to rectify and improve original circuit, simplified the lamp installation process, can directly install and use; Need not to produce electric ballast simultaneously, can directly adopt the Inductive ballast in the traditional fluorescent lamp tool mount pad, saved and manufactured cost; The wildcard that can really realize LED daylight light fixture by this circuit is general.

Above only the act the present invention in the spiritual category that does not break away from the utility model creation, is familiar with any simple modification and the distortion that those skilled in the art did of this technology conveniently to illustrate, still belongs to protection range of the present utility model.
