Just look the same on the big chip and the small chip. The lamp beads used by led lights are different, according to the number of different lights used under the same lighting brightness, taking into account the heat dissipation requirements of the circuit arrangement, there is a difference in the size of the wick, in principle, there is no good or bad.
Under the same lighting brightness, with the wick of high-power lamp beads, the number of lamp beads is small, the wick will be smaller, and the wick will be larger. There is a cost constraint on the cost performance of the manufacturer.
From that point of view, from the parameter point of view, the small chip is good, because the light efficiency is high from the production point of view, high power is good, because welding an LED is equivalent to welding N low-power LED lights from the cost-effective point of view, medium power is good, his characteristics are between the above two
