Abstract
The utility model discloses an electronic ballast, which comprises a communicate filter circuit, which is connected with an input power supply, and is provided with a digital control circuit. An output end of the digital control circuit is connected with a main lamp output circuit of the electronic ballast by a semi-bridge driving circuit of the electronic ballast and a LED lighting circuit. For the ballast is provided with the main lamp switch control circuit and the control circuit of the LED lighting power supply through the digital control circuit, when in use, the more than two light sources connected with the ballast can be chosen by switching off the power supply, according to the different demands, and the main lamp lighting and the LED lighting can be realized independently or simultaneously.
Description
Technical field
The utility model relates to a kind of electric ballast of lighting.
Background technology
The electronic ballast function of existing lighting is single, and a ballast can only connect a light source, the two states that can only open or extinguish this light source.In actual use, having many times often only needs low light level illumination to get final product, and because existing ballast can only be opened or close the light source that it connected, its fluorescent lamp is lighted fully, and consume electric power is used inconvenient.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of perfect in shape and function, easy to use, reliable electric ballast.
The technical scheme that the utility model adopted is:
A kind of electric ballast, it is characterized in that: comprise the current rectifying and wave filtering circuit that connects the input power supply, current rectifying and wave filtering circuit is connected with a digital control circuit, one road output of digital control circuit connects electric ballast king light output circuit by the electric ballast half-bridge drive circuit, and this digital control circuit also is connected with the LED lighting circuit.
The beneficial effects of the utility model are: because this ballast is provided with the control circuit of the ON-OFF control circuit and the auxiliary LED mains lighting supply of king light by digital control circuit, during use, can be according to no needs, thereby select the work of the two or more light sources that ballast connected by power cutoff, can be separately or realize that simultaneously king light illumination and LED lighting source are luminous.Ballast of the present utility model is except that keeping original function, when the illumination place does not require too strong light, can be only luminous with the LED lighting source, reach purpose of power saving, and when king light and LED lighting source simultaneously during bright lamp, led light source can satisfy the requirement of throwing light on and the life atmosphere in increase place.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the theory diagram of the utility model electric ballast;
Fig. 2 is physical circuit figure of the present utility model;
Fig. 3 is the schematic appearance of the utility model product embodiments.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of electric ballast of the present utility model, comprise the current rectifying and wave filtering circuit that connects the input power supply, current rectifying and wave filtering circuit is connected with a digital control circuit, one road output of digital control circuit connects electric ballast king light output circuit by the electric ballast half-bridge drive circuit, and this digital control circuit also is connected with the LED lighting circuit.
Wherein, as preferred implementation, digital control circuit can be the block switch circuit, as adopting HL2608 block switch module I C1, by this circuit king light and the luminous element that is connected the LED lighting circuit is carried out segmentation control.
Described LED lighting circuit comprises the drive circuit that is used for the driving LED illumination light-emitting and/or is used for the luminous drive circuit of driving LED flicker.
Wherein, the drive circuit that is used for the driving LED illumination light-emitting is used to connect the LED luminous element that illumination is used as the low light level and drives, this drive circuit comprises the triode Q1 of linking number word control circuit output, and the output pin of this triode Q1 connects LED light string L1-3.In addition, for ease of installing, using, be used for the LED luminous element that drive circuit connects and be directly installed on ballast housing as shown in Figure 3.
Being used for the luminous drive circuit effect of driving LED flicker is to drive the LED lamp string that it connected, as colorful, use when flasher is interspersed the space, increase the atmosphere in place, place, it comprises a flicker control module IC2, the input linking number word control circuit of flicker control module IC2, output connects LED lamp L4-6, L7-9, L10-12 by triode Q2, Q3, Q4.
As preferred embodiment, as shown in Figure 2, this ballast has the king light control circuit simultaneously, be used for the drive circuit of driving LED illumination light-emitting and be used for the luminous drive circuit of driving LED flicker, makes its feature richness, result of use good.
In conjunction with Fig. 2, the course of work of electric ballast of the present utility model is as follows:
Ballast incoming transport power supply, after circuit is switched on for the first time, block switch module I C1 non-output signal, the king light circuit working, promptly king light LAMP is bright; 2, the 7 pin output signals of energising back block switch module I C1 for the second time within the outage back several seconds, triode Q1, Q5 conducting, L1-3 is bright for the LED lamp, and the base current of triode Q7 is by short circuit, so the king light circuit do not work, and promptly king light does not work; Cutting off the power supply within several seconds for the third time once more, 7, the 8 pin output signals of energising back block switch module I C1 make triode Q1 conducting, flicker control module IC2 work, triode Q2, Q3, Q4 circulation conducting, it is its LED lamp L4-6, L7-9, L10-12 that connects bright lamp that circulates, the 2 pin no signals output of block switch module I C1, triode Q5 does not work, the king light circuit working, and king light LAMP is bright.Certainly, use needs according to difference, it is bright with the LED lamp L1-3 while also can be set at circulate bright lamp or LED lamp L4-6, L7-9, L10-12 of independent LED lamp L4-6, L7-9, L10-12.
Certainly, the invention is except above-mentioned execution mode, and other equivalent technical solutions also should be within protection range of the present utility model.
