Length, fast response time, safe, environmentally protective, LED has not only been successfully applied to some general occasions illuminations, but also it at present
Special advantage such as luminous intensity is high, service life is long, the environmentally protective demand that disclosure satisfy that special occasions, with the day of resource
Beneficial exhausted, LED illuminations will substitute lighting source of the traditional lighting as mainstream.
But at present since the specification of LED is different, LED drive power is also required to export same power ability point
Bright LED, this is resulted in just needs to use different driving powers for different products, different which results in needing to purchase
Material variety specification produces different driving powers, to purchasing management brings inconvenience, while stock can be caused more, accounts for
With substantial amounts of space and fund.
Utility model content
The utility model aim is：A kind of LED drive power with PCU Power Conditioning Unit is provided, which can fit
With the LED of plurality of specifications, need to only purchase the material change of minority can produce driving power, greatly reduce cost, reduce company
Burden.
The technical solution of the utility model is：A kind of LED drive power with PCU Power Conditioning Unit, includes filtering successively
Circuit, rectification circuit, circuit of power factor correction, pwm control circuit, voltage conversion circuit and rectification circuit, further include at the same time
One PCU Power Conditioning Unit, the input terminal of the PCU Power Conditioning Unit and the sampling end of voltage conversion circuit connect, the power tune
The output terminal of regulating device is connected with pwm control circuit, and the PCU Power Conditioning Unit is used to change the pwm control circuit output
Watt level.
Further, the PCU Power Conditioning Unit is potentiometer or toggle switch.
Further, the PCU Power Conditioning Unit includes signal detection module and power conditioning module, wherein, the work(
Rate adjustment module includes multichannel and adjusts circuit, including at least one resistance and current for being opened and closed per the adjusting circuit all the way
The switch of circuit is adjusted, the signal detection module is used to detect the big of the currently used total resistance value of the PCU Power Conditioning Unit
It is small.
Further, the resistance sizes are identical or different.
Further, including at least three road power conditioning circuitries.
During concrete application, according to the LED of different size, when needs use PCU Power Conditioning Unit constantly to open or close
One or more in the PCU Power Conditioning Unit adjusts circuit, by varying the size of resistance, to change the size of electric current, from
And change the size of pwm control circuit output power.
The utility model has the advantages that：The LED of the applicable plurality of specifications of the driving power, therefore only need in process of production
A small number of materials is purchased, cost is greatly reduced, reduces the burden of company, reduce the pressure of company stock and fund.
