For rectangular voltage when, OUT1, OUT2 export low-voltage simultaneously, warm white, just light simultaneously in vain, different ratios, each group output
Brightness is different, reaches the effect of toning.
Constant flow module：RS1, RS2, RS3, RS4, RS5, RS6, RS7, RS8, U1, U2, adjust RS resistance, thus it is possible to vary
U1, U2 internal reference voltage, so as to reach constant current.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
