Description
Technical field
This utility model relates to a kind of power supply, specifically a kind of LED drive power.
Background technology
In today that energy crisis and climate warming problem are increasingly severe, energy-conservation and environmental protection has become social focus subject under discussion.LED
Because of its efficiently, energy-saving and environmental protection, life-span length, rich color, volume flicker little, resistance to, that reliability is high, regulation and control are convenient etc. is all
The features such as many advantages get more and more people's extensive concerning it is considered to be 21 century the most promising lighting source.Traditional white heat
Lamp, daylight lamp efficiency is low, power consumption is high；Fluorescent lamp power saving, but service life is short, frangible, and there is mercury pollution in garbage；High
There is the shortcomings such as efficiency is low, power consumption is high, the life-span is short, hazards of electromagnetic radiation in intensity gas discharge lamp；If can take with LED illumination
For current poor efficiency, the traditional lighting of highly energy-consuming, the most urgent energy shortage and ecological deterioration can be alleviated undoubtedly
Problem.C-V characteristic and temperature characterisitic due to LED self so that it is quick that the sensitivity of electric current is higher than voltage by LED
Sensitivity, therefore can not be powered directly to LED by traditional power supply.Therefore, make lighting source with LED and first will solve electricity
How the problem that source drives, provide that stability is high, the LED power circuit of low cost becomes the research direction of Ge great LED producer.
Utility model content
The purpose of this utility model is to provide a kind of LED drive power, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of LED drive power, including master switch power pack, sampling module, MCU controller and modular converter, described
Master switch power pack connects MCU controller, 220V alternating current and modular converter respectively, and MCU controller is also respectively connected with and turns
Die change block and sampling module, sampling module also connects 220V alternating current.
As this utility model further scheme: described modular converter is 0～10V modular converter, is turned by 0～10V voltage
It is changed to 5V.
Compared with prior art, the beneficial effects of the utility model are: this utility model LED drive power is by input electricity
Pressure and output voltage carry out dual sampling, thus control the voltage that Switching Power Supply output is stable, and are driven LED, this
Sample can be realized as full voltage and covers, and has the effect of dual light modulation, and system structure is simple, and low cost, volume is little, equally
It is also applied for LED lamp, daylight lamp and electric filament lamp etc., applied widely.
Accompanying drawing explanation
Fig. 1 is the schematic block circuit diagram of LED drive power.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, in this utility model embodiment, a kind of LED drive power, including master switch power pack, sampling
Module, MCU controller and modular converter, described master switch power pack connect respectively MCU controller, 220V alternating current and
Modular converter, MCU controller is also respectively connected with modular converter and sampling module, and sampling module also connects 220V alternating current；Institute
Stating modular converter is 0～10V modular converter, and 0～10V voltage is converted to 5V.
Operation principle of the present utility model is: refer to Fig. 1, and master switch power supply provides power supply, master switch power supply unit for LED
Dividing and 220V alternating current is converted to 0～10V voltage output, 220V alternating voltage is sampled by sampling module simultaneously, if handing over
Stream 220V spread of voltage or generation phase shortage situation, send this situation signal to MCU control module, MCU control module
Master switch power pack is adjusted by output PWM ripple；It addition, modular converter master switch power pack is exported 0～10V
Voltage is changed, and the voltage of conversion is also carried out gathering and identifies by MCU control module, thus by PWM ripple to master switch electricity
Source part is also carried out controlling, thus controls the light modulation of LED, it is achieved full voltage covers, the effect of dual light modulation, Er Qiejie
Structure is relatively easy, low cost, and volume is little, can equally be well applied to LED lamp, daylight lamp and electric filament lamp etc., applied widely.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.
Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only comprises
One independent technical scheme, this narrating mode of description is only the most for clarity sake, and those skilled in the art should be by
Description is as an entirety, and the technical scheme in each embodiment can also be through appropriately combined, and forming those skilled in the art can
With other embodiments understood.
