Embodiment
Be described in detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model light adjusting circuit device.
Fig. 1 shows a kind of circuit structure of light adjusting circuit device 100, and it comprises power supply 10, low colour temperature LED light source module 301, high color temperature LED light source module 302.The input incoming transport civil power of power supply 10.Low colour temperature LED light source module 301 is connected with the anode of power supply 10 output with the anode of high color temperature LED light source module 302.The negative terminal of low colour temperature LED light source module 301 is connected with the input of the first flow restricter 201.The negative terminal of high color temperature LED light source module 302 is connected with the input of the second flow restricter 202.The output of the first flow restricter 201 is connected with the first end of the second potentiometer 102.The output of the second flow restricter 202 is connected with the second end of the second potentiometer 102.The adjustable termination of the second potentiometer 102 enters the negative terminal of power supply 10 output.At the two ends of the second potentiometer 102, also parallel connection has access to the first potentiometer 101.Second potentiometer 102 is necessary for three end adjustable potentiometers.First potentiometer 101 can be two ends potentiometer also can be three terminal potential devices.The first end of the first potentiometer 101 is connected with the first end of the second potentiometer 102.The adjustable end of the first potentiometer 101 is connected with the second end of the second potentiometer 102.The adjustable end ground connection of the second potentiometer 102.
First flow restricter 201 and the second flow restricter 202 are linear adjustable current galvanostat and/or the switching mode current adjustment galvanostat that can regulate size of current by changing peripheral hardware resistor resistance.Therefore, just can change by the resistance value size changed between output to D.C. regulated power supply 10 negative (-) end the size of current flow through on LED light source module.Thus regulate brightness and the colour temperature of LED.
The adjustment to LED colour temperature can be realized by the second potentiometer 102 regulating three ends adjustable.
Adjustable termination due to the second potentiometer 102 has entered negative (-) end of power supply 10 output, and the resistance value making the first flow restricter 201 access like this is Rc1; The resistance value that second flow restricter 202 accesses is Rc2; And Rc1+Rc2=Rc, Rc are a fixing resistance.
When the adjustable end of adjustment second potentiometer 102, when making Rc1=Rc2, at this time the current settings of the first flow restricter 201, second flow restricter 202 is identical value, and making to flow through identical with the electric current of the high color temperature LED light source module 302 therefore mixed bright dipping of light that at this time low colour temperature LED light source module 301 and high color temperature LED light source module 302 send of low colour temperature LED light source module 301 is neutral white.
When the adjustable end of adjustment second potentiometer 102, when making Rc1<Rc2, at this time the current setting value of the first flow restricter 201 is greater than the current setting value of the second flow restricter 202.The electric current flowing through low colour temperature LED light source module 301 is made to be greater than the electric current flowing through high color temperature LED light source module 302, just make light intensity that low colour temperature LED light source module 301 sends in high color temperature LED light source module 302, the mixed bright dipping of light that now LED light source module 301 and high color temperature LED light source module 302 send is warm colour light.
When the adjustable end of adjustment second potentiometer 102, when making Rc1>Rc2, at this time the current setting value of the first flow restricter 201 is less than the current setting value of the second flow restricter 202.The electric current flowing through low colour temperature LED light source module 301 is made to be less than the electric current flowing through high color temperature LED light source module 302, light with regard to making low colour temperature LED light source module 301 send is weaker than high color temperature LED light source module 302, and the mixed bright dipping of light that now LED light source module 301 and high color temperature LED light source module 302 send is cool colour light.

When Rw resistance is turned down, resistance Rc, also along with reduction, makes Rc1 be reduced to Rc1 ＇ like this; Rc2 is reduced to Rc2 ＇ simultaneously, and Rc1:Rc2=Rc1 ＇: Rc2 ＇.Make the electric current flowing through low colour temperature LED light source module 301 and high color temperature LED light source module 302 increase like this, therefore brightness also just adds thereupon simultaneously.And do not change because Rc1:Rc2=Rc1 ＇: Rc2 ＇ also just achieves colour temperature like this.
When Rw resistance is heightened, resistance Rc, also along with rising, makes Rc1 raise as Rc1* like this; Rc2 raises as Rc2* simultaneously, and Rc1:Rc2=Rc1*:Rc2*.Make the electric current flowing through low colour temperature LED light source module 301 and high color temperature LED light source module 302 reduce like this, therefore brightness has also just decreased simultaneously.And do not change because Rc1:Rc2=Rc1 ＇: Rc2 ＇ also just achieves colour temperature like this.
Achieve the adjustment by regulating the first potentiometer 101 pairs of LED luminance like this, and do not change the colour temperature of LED light emission device while regulating LED luminance.
