The LED chip can be divided into low-power, middle power and high-power chips according to different size. The common high power LED chip sizes are 38*38mil,40*40mil,45*45mil (mil is one measurement unit, a mil is one thousandth of an inch, that is 1mil=1/1000inch=0.00254cm=0.0254mm). The chip size can be customized based on customer requirements. And the specific chip size depends on actual production levels of the different chip manufacturers, there are no specific rule.
