led light solution
At present, led light drive solution is divide into two type: SMPS—Switching Mode Power Supply and AC/DC led driver.what are the characteristics of these two led light solution?
1、reliability
In the wake of developments in led wafer technology. the led light resource can reach more than 50000 hours ~ 100000 hours. but SMPS is unreliable and low in efficiency .
AC/DC led driver removes the bottleneck problem restricting the development of SMPS .
and it stability of work temperature. in the course of energy conversion, led production want to do best job in good conditions. the method can insure that led life time can reach more than 500000 hours ~ 100000 hours.
SMPS IC
Integrate IC led power
Discrete components led power
2、Cost
The SMPS—Switching Mode Power Supply is complex solutions also increase the total cost of the led driver solution. AC/DC led driver is simpler to design, AC/DC led driver is the key to designing a led light solution that truly meets optimization goals.
it has advantage of low cost and high reliability to control led light solution by AC/DC led driver.
