LED driver IC

With the continuous development of led lighting, the led lighting system are increasingly being applied to all led lighting areas .there are not any advantage if the inappropriate led driver is selective. so   the led driver IC(integrated chip)   is important for led lighting design on led lighting field. followings we will talk about technology detail of led drivers.

*The voltage input range should be in DC8-40V, the wide input voltage adapt to various design. the suppose voltage was fluctuations as grid
voltage change. at moment the fluctuations voltage will damaged led.we’ve got to get the wide input voltage on your design.

* The require output currently of led driver as 1.2-1.5A , the input currently of 1W led source as 350mA , the input currently of 3W led source as 700mA . the high power led driver can support high power led source.
so we will require sufficient output currently to driver led source. by the way, the led driver don’t output currently with full energy ,the work status of output currently is best as output rage at 70-90%. the solution can increased led server time.
*The led source will require constant output current and the led source can lit constant bright. the output currently should be as small as possible on same batch of led driver. this best way for discrete control . and it can keep the finial production consistent.
*LED encapsulation help the led chip dissipate heat rapidly.*The key conditional of comply with CE and UL certification is that
the led drive ic has capability of anti nose and anti EMI. it is necessary to select appropriate construct and production technology for your project.
* The work power of led driver should be less than 0.5W, and the work frequency should be big than 120Hz, to avid interference from power frequency noise. the led lighting can not do without led drive ic, so the led source will require multi – function led drives.
