The technology for LED Driver

Do you know what is LED driver?

Or do you know what is the standard of best LED driver?

LED is the solid state light source.How can we keep the current characteristic working steady especially in current variation? 

Here are the key points:

  1. Avoid the driver current to exceed the maximum rating to keep the LED load working steady.
  2. Keep all the illuminate and CRI in accordance to get higher output.
  3. Guarantee the load current of LED is steady all the time.

Also,the main technology requirement of LED driver:

  1. Power
  2. Maximum power output
  3. Working temperature range 
  4. PF >0.9
