Description
Technical field
The utility model relates to a kind of multistage aperture LED control circuit.
Background technology
Comparatively conventional incandescent and electricity-saving lamp have energy-conserving and environment-protective to LED, long service life, employing solid encapsulation be convenient to the advantages such as transport and installation, under the guide of the strategy of sustainable development, energy-saving and emission-reduction thought is constantly promoted, current country more and more payes attention to lighting energy saving and environmental issue, carrying out energetically using LED bulb, along with the development of LED technology, electricity-saving lamp and incandescent lamp will be replaced by LED in the near future.LED is in application placed in the middle also more and more extensively, has been widely used in pendent lamp, ceiling light, bathroom lamp, cabinet lamp etc. at present.
Traditional LED lamp can only realize overall Kai Heguan usually, optionally cannot light the bulb of certain part specified quantity, easily cause the waste of electric energy.In addition, traditional LED lamp illuminating effect is single, cannot realize the adjustment of multistage aperture.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and supports that multistage different radii aperture regulates, that illuminating effect is good, electric energy loss is low multistage aperture LED control circuit.
The purpose of this utility model is achieved through the following technical solutions: multistage aperture LED control circuit, comprise AC-DC converter, single pole multiple throw and multistage aperture LED, described multistage aperture LED comprises at least two ring-type LED-baseplate, each ring-type LED-baseplate stretches out successively, each ring-type LED-baseplate is provided with a LED string, each LED string comprises multiple LED bulb; The ac input end of described AC-DC converter connects mains supply, the DC output end of AC-DC converter is connected with the power input of single pole multiple throw, the enable signal input connecting valve drive singal of single pole multiple throw, the output of single pole multiple throw is connected with each LED string respectively.
Described multistage aperture LED is three grades of aperture LED lamps, and the quantity of LED string is three.
Described LED string comprises eight LED bulb.
The surface of described ring-type LED-baseplate is provided with reflector.
The beneficial effects of the utility model are:
1) support the adjustment of multistage different radii aperture, can need the luminous aperture of free adjustment according to user, illuminating effect is good and effectively can reduce electric energy loss;
2) reflector that LED-baseplate surface is arranged effectively can strengthen illumination intensity, improves luminous efficiency;
3) adopt single pole multiple throw to realize multi channel selecting, structure is simple and stability is strong, long service life.
Accompanying drawing explanation
Fig. 1 is the utility model circuit structure block diagram;
Fig. 2 is the utility model multistage aperture LED lamp structure schematic diagram;
In figure, 1-ring-type LED-baseplate, 2-LED bulb.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection range of the present utility model is not limited to the following stated.
As shown in Figure 1 and Figure 2, multistage aperture LED control circuit, comprise AC-DC converter, single pole multiple throw and multistage aperture LED, described multistage aperture LED comprises three ring-type LED-baseplate 1, each ring-type LED-baseplate 1 stretches out formation three grades of aperture LED lamps successively, each ring-type LED-baseplate 1 is provided with a LED string, each LED string comprises eight LED bulb 2; The ac input end of described AC-DC converter connects mains supply, the DC output end of AC-DC converter is connected with the power input of single pole multiple throw, the enable signal input connecting valve drive singal of single pole multiple throw, the output of single pole multiple throw is connected with each LED string respectively.Can control single pole multiple throw gating by switching drive signal, the corresponding LED string of conducting, thus achieve the control of three grades of apertures, the LED string luminescence of different iris radius can form different illuminating effects.
In the present embodiment, the surface of described ring-type LED-baseplate 1 is provided with reflector, can increase luminous efficiency.
The above is only preferred implementation of the present utility model, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection range of the utility model claims.
